Cutting window openings

Modern technologies make it possible to implement any consumer requests for the modification of premises during a major overhaul. At the same time, more often than not just replacing windows, but a full-fledged modeling of the space. It becomes necessary to cut a window in a brick wall or expand an existing opening. The new design allows you to individualize the room, improve lighting, and, using modern technologies, also avoid heat loss.

It is noteworthy that not only apartment owners in multi-storey buildings are striving to modify the premises, but also people in private houses. The question of how to cut a window opening in a brick wall is rarely of interest to apartment owners in new buildings, where this is most often not allowed by the standards.

Technologically, using diamond cutting, you can cut or expand an opening of any size and structural complexity. However, the work is not always feasible, for example, the bearing wall of the basement floors is under high loads, which means that cutting is permissible only after careful research. In new buildings, enlarging or creating new holes is not allowed. But in private houses, problems with modifications practically do not arise. cardinal design ideas, such as expanding a window opening, will require only the experience of specialists, and not complex architectural calculations and permissions.

According to the material of the structure, various types of walls are distinguished. brick, lightweight concrete, monolithic (concrete) and many others. Each type has its own standards for thickness, withstand load, material processing features. For example, if you want to make a window in a brick wall, then you need to be aware of the risk of masonry destruction and methods to prevent it. Concrete and metal structures have their own equally important characteristics.

Diamond cutting of window openings

Diamond cutting of window openings

Many people believe that the easiest and most affordable way to increase openings is manual work. But few people take into account that the seams are uneven, require additional finishing, and the work itself is very dusty and dirty. But the cost of these manipulations is low. And although diamond cutting cannot boast of a cheap price, otherwise this technology only shows its best side.

The advantages of cutting with a tool with diamond segments are:

  • High speed of work carried out.
  • Hygienic. no dust when cutting with a hydraulic saw.
  • The absence of vibrations, which is essentially the answer to the question of how to cut a window in a brick wall in an old building without provoking destruction.
  • The noise level is significantly lower than when performing similar tasks with a hammer drill. And, as we know, noise level control in Kiev is an important issue.
  • Smooth cut of any shape.

It will not be difficult for residents of the capital to order the creation of new openings at the best price. Almarez provides drilling, cutting, expansion, dismantling and reinforcement services. Each task is performed in accordance with the rules and standards for performing similar tasks.

Punching openings in brick walls: how to cut and enlarge a window opening using diamond cutting?

Each construction material has its own characteristics. Expanding the doorway in a concrete wall allows you to get an even cut along the entire length, which cannot be said about brickwork. When working with masonry, some precautions must be taken to avoid additional deformations.

Before expanding the doorway in the brickwork, reinforcement must be made directly above the door. For this, a row of bricks is knocked out about 150-300 mm wider than the opening and a jumper is laid there. After that, markings are carefully made on both sides of the wall. The wall is cut a little more than half on each side and after that the cut area is carefully dismantled.

For more convenience in the production of work, the opening can be cut in several stages, dividing the dismantled area into several smaller ones. This will make it easier to dispose of construction waste after the end of the work.

Expansion of a window opening in a brick wall is carried out in the same way. But at the same time, it becomes necessary to perform work at height. To do this, it is imperative to comply with the safety rules for working at heights and the use of safety equipment. In the absence of experience in such work, it is better to refuse to perform them independently, and invite industrial climbers.

Dust-free diamond cutting of openings in concrete: how to make an opening in a load-bearing wall or move it; how to expand a window opening?

Typical apartment layouts do not always meet the wishes of their owners, and often there is a need for redevelopment. Changes in the boundaries and sizes of premises are often associated with the transfer or expansion of openings, both door and window. This type of work requires not only an accurate calculation, but also the use of a special tool.

The simplest, but not the most effective, method is to punch and widen the holes with a hammer drill or electric jackhammer. But this method is very laborious and requires a lot of physical effort. In addition, a large amount of dust and debris appears in the process. Much more efficient and faster and less noisy diamond cutting of doorways and windows. It is this technology that is increasingly used in redevelopment.

Doorways in load-bearing walls: dust-free cutting of wall openings, enlargement and relocation

When starting redevelopment, it is necessary to take into account building codes, as well as structural features. Moving or expanding the doorway in the load-bearing wall should not weaken the structure of the house and lead to deformations. That is why the project of any redevelopment must be approved by the supervisory authorities.

When constructing an opening in a load-bearing wall, it is necessary to take into account the change in loads and, if necessary, perform reinforcement. This is achieved by additional reinforcement of the new opening, reinforcement with metal structures, and in some cases, buttresses are used. Often, during operation, a temporary reinforcing structure is required, which reduces the load at the site of the new opening.

For cutting openings in load-bearing walls, it is most effective to use a cutting tool with diamond discs. Of course, the noise level during diamond cutting is lower than during the operation of a hammer drill, but it is still available, and in this regard, it is better to carry out work during the day on weekdays, so as not to create discomfort for your family and neighbors. It will not be possible to completely get rid of dust, but its amount can be significantly reduced by using an industrial vacuum cleaner in conjunction with a cutting tool. Do not forget about personal protective equipment: respirator, goggles or mask and earmuffs from noise.

Of particular difficulty are curved openings, for example, arched. The wall is cut out in separate segments that coincide as much as possible with the shape of the future opening. However, it will not be possible to achieve a complete match using only the cutting tool. The final look of the arch is given using plaster or drywall sheets.

Diamond cutting and reinforcement of openings

First of all, it is a low level of vibration and noise during operation. This effect is achieved thanks to the shock-free technology and high speed of rotation of the cutting wheel. Of no small importance is the safety of diamond cutting. in the process there is no scattering of concrete fragments, and the amount of dust that rises into the air is minimal.

The equipment used in this technology is very accurate, so all the specified parameters will be observed without the slightest deviation. The wall will be cut exactly according to the markings, and the corner will be intact. It also eliminates the risk of cracking when cutting concrete or brick walls. So this method can be safely used in residential premises.

According to the existing legislation, the creation of holes and openings in the walls that are load-bearing requires a preliminary development of the project with the receipt of documentation for it. And the work can begin no earlier than you have a technical conclusion on hand, indicating that redevelopment is possible. Diamond cutting of openings in load-bearing walls, without permission, at best threatens with a fine from the supervisory authorities.

One of the design stages is an engineering survey, the purpose of which is to clarify the technical condition of a building and its structures. In the process, you will have to provide access not only to your apartment. The engineer should be able to inspect the apartment below and above the riser. for any redevelopments that have already been made. Based on the information received, a decision will be made whether it is possible to make an opening in the load-bearing wall.

[/ vc_toggle] [vc_toggle title = “What are the steps involved in cutting doorways?” open = ”false”]

To make a doorway in a load-bearing wall, you will need to perform the following work:

  • Wall markings.
  • Drilling test holes in the bulkhead.
  • Waterproofing the floor in the room where the work will be carried out.
  • Perimeter cutting or perimeter cutting into transportable parts. if the house is panel.
  • Installation of metal structures that reinforce the opening.
  • Breakdown of large pieces of the wall with a concrete breaker and taking them out of the working field.

[/ vc_toggle] [vc_toggle title = “What are the ways to strengthen openings in load-bearing walls?” open = ”false”]

The device of openings in load-bearing walls is necessarily accompanied by their strengthening. And it can be done in several ways:

  • Double-row, box-type. this is a whole complex of works to create a complex structure from a channel and a corner, and sometimes using I-beams. It is used to create openings in load-bearing walls, very thick or requiring special security measures.
  • Single-row. using the installation of an H-shaped structure from a steel channel. This reinforcement is mounted on both sides of the wall, before the start of cutting. The construction is very reliable and with a high load-bearing capacity.
  • Corner. the edging of the opening is made with a steel corner. Most often, this method is used when organizing openings in the walls of panel houses (type P44T). The parameters of the corner change depending on the dimensions of the floors and the number of storeys of the house.

[/ vc_toggle] [vc_toggle title = “What kind of diamond cutting attachments can I work with a brick wall?” open = ”false”]

Punching openings in brick walls can be done with two types of tools. For interior work, or in rooms with a fine finish, it is better to use a hand cutter, on an electric or gas drive. Diamond discs in such devices are small, up to 40 cm in size.Accordingly, the maximum cutting depth is up to 80 cm.The tool does not require serious preparation of the room for work, which allows you to use the room in almost the same mode.

Wall saws are also used, which already belong to construction equipment. They should be chosen if there is a large-scale redevelopment in the apartment, with subsequent finishing work. Such a machine works more accurately and at a higher speed than a hand cutter, and its maximum cutting depth is greater.

[/ vc_toggle] [vc_toggle title = “How is window openings reinforced?” open = ”false”]

Cutting window openings, as well as door openings, involves the installation of reinforcement. over, the type of its construction and the moment of installation depends on what material the wall itself is made of. So, when expanding a window opening in brickwork, preliminary strengthening is required. That is, first, above the window, you need to hollow out holes for a channel or I-beam, on both sides. Further, the mounts are recessed into the wall and pulled together with studs. Only then can you start cutting.

Openings in panel or monolithic walls are reinforced after cutting. Here, work is carried out using a steel corner. it is framed by the inner and outer edges of the window. The strips are attached to the wall with anchors, and welded together. Further, both edges, using welding, are tied with strips of steel equal in thickness to the angle. The dressing step should be at least 20 cm from one strip to another.

[/ vc_toggle] [vc_toggle title = “What points should you pay special attention to when expanding wall openings?” open = ”false”]

Expanding the opening in the load-bearing wall is half the battle. And the second half is its high-quality strengthening. And there are a few secrets here:

  • You cannot fasten the channel or corner to the wall by drilling both elements through and welding them together with a pin. The sides of the structure must be attached to the wall independently. each with its own pin.
  • Steel tie strips should be welded to the reinforcement system along the entire length of their sides, and not at several points.
  • The pin sockets must be drilled at a 45 degree angle. Next, we weld the pins adjacent to the channel. The remaining length immediately, while the metal is heated by welding, bend it with a sledgehammer and scald.
  • After completing the installation of the reinforcing structure, it is imperative to fill in all the voids between the metal and the wall body. This is done using a sand-concrete mixture marked M200 or M300.

OPENING IN THE BEARING WALL

The production of an opening in the load-bearing wall is due to interference with the load-bearing elements of the building. For such a reconstruction of the wall, a project (calculation) for the manufacture and, if necessary, permission for redevelopment of the premises is required.

Opening in the load-bearing wall. this is cutting out a part or fragment of a load-bearing wall, followed by reinforcing this part with a metal frame.

FOR DIAMOND CUTTING OF OPENINGS

The cost of manufacturing the opening includes: cutting along the contour, dismantling for lifting parts up to 40-60 kg. The price is valid for the diameter of the reinforcement up to 18mm, the cell is not less than 20x20cm, no more than 2 layers. Making holes from saw cuts. by agreement.
The cost of work does not include: removal of garbage, final cleaning of the premises, pasting with foil of nearby objects and structures. negotiated separately (furniture, double-glazed windows, floor coverings, walls, ceiling).

When working at night, height over 2 meters: 20% to the cost of work.
Minimum cost of work: Moscow, within the Moscow Ring Road: from 8,000 rubles. Outside the Moscow Ring Road: from 10,000 rubles. Over 10 km: 30 rubles / km.

The noise level during cutting has permissible standards determined by the Resolution of the Government of Moscow N 73-PP “On the procedure for reorganization and (or) redevelopment of residential and non-residential premises in residential buildings on the territory of the city of Moscow”.

TECHNOLOGY

Sawing the structure into “fragments” with concrete saws using diamond tools. called diamond cutting of openings.

DIAMOND CUTTING OF OPENINGS. WORK FOR A PROFESSIONAL

Today, on the market of construction services, any team of workers is ready to undertake work on the manufacture of an opening, using an “angle grinder” and other unacceptable shock-destructive equipment. When using this technique, concrete (reinforced concrete) can lose its properties, the connection between reinforcement and concrete is disrupted, microcracks are formed, which leads to a decrease in the overall resistance of the building.

A gross violation of the production technology and deviation from design decisions can create a dangerous situation: an opening in the load-bearing wall made by unqualified “specialists” can lead to sad consequences. Do not trust inexperienced teams and incompetent specialists to carry out the work. It is more difficult and more expensive to fix a defective opening than to make a new one.

HOW WE PERFORM DIAMOND CUTTING OF OPENINGS

Cutting, like diamond drilling for walls, is a versatile and best method to create openings in floors and walls when you need windows, doors and other holes.

SAW IN PARTS

When cutting out, the falling of concrete fragments on the floor is not allowed. This situation can lead to the formation of cracks or collapse of the floor. Therefore, diamond cutting of openings in concrete, in apartment buildings, is carried out by us into separate parts, weighing about 40 kg.

ACCURACY AND SAFETY OF WORK

According to the requirements of design organizations, we make openings in the walls using the diamond cutting method. the result is precise dimensions and smooth concrete parts without visible chips and cracks.

Using temporary unloading racks in our work, we guarantee the integrity of the walls and floors.

DUST AND DIRT

The manual concrete machines we use, such as Husqvarna, Messer, are equipped with a wet cutting kit with low water consumption, which prevents the formation of dust.

Concrete-water sludge is absorbed into a special rag or absorbed by a special mixture, which prevents possible leaks to the lower floors in apartment buildings. In rooms with decoration, it is necessary to paste over the wallpaper, ceiling and nearby objects with foil.

NOISE

2 simple hacks for drilling without making a mess

During operation, the resulting noise has an acceptable level. For example. the noise from the punch is much louder.

WORKING TIME

On average, a standard opening is 2100x900mm, in panels up to 20 cm thick. It is made (cutting) in 1-2 days. We work every day and on weekends, where there are no restrictions.

EXPERIENCE

With years of experience in the industry, our safety standards and work practices will benefit you and your project.

TYPES OF MADE OPENINGS

We offer safe cutting of walls using so-called concrete saws. As a result, the edges remain smooth and do not require any additional processing. To minimize dust formation, water is used to also cool the disc.

CUTTING DOOR OPENINGS

We have extensive experience in expanding and cutting new wall openings for doors. You can be sure that your doors will be installed correctly and evenly.

As a rule, we manufacture doors in concrete and brick walls, with a thickness of 10.60 cm and more. This is achieved with specialized wall saws that cut the material evenly and achieve precise dimensions.

What openings can we cut?

  • doorways in “high-rise buildings”
  • openings in individual houses and buildings
  • separate entrance to the building
  • in the basement, entrance to the basement
  • firefighters
  • garage door
  • doorways and interior openings in houses, cottages and premises (private and industrial sector)

Please contact our company. your opening must be done correctly the first time!

CUTTING OPENINGS IN THE FLOOR

An opening in the floor, for example for a staircase, may be needed during a new construction or during the renovation of your apartment, building or house.

When converting an attic or basement into a living space, as well as in the process of combining apartments. Horizontal sawing is ideal for creating passages or holes in concrete floors.

These are, as a rule, flat surfaces, such as reinforced concrete floors, floors, pavements, as well as other concrete and asphalt surfaces.

CUTTING OF WINDOW OPENINGS

Sometimes replacing old windows may require cutting large holes for more modern windows. In addition, some customers may decide to change the location of the window opening to create a completely new look.

Many older houses have small windows in the basement. They do not let in enough light and they do not allow a person to leave in case of an emergency. Thus, cutting or widening a basement window is a great way to increase the flow of light and to ensure the safety of people in the basement. Cutting a window opening can be done from any side, both from the inside and outside.

Working outside is preferable as the slurry (a mixture of concrete and water) simply sinks into the ground. If cut from the inside. additional costs can often arise in connection with the necessary preparation of the drainage system. Using diamond cutting allows you to create perfect, precise corners, without chips or irregularities. Depending on your needs, our specialists can skillfully expand or cut a new window in reinforced concrete, brickwork, wall panels. A clean cut helps maintain the integrity and appearance of your property.

If you are building or renovating a house, our company is ready to do the job quickly and efficiently. Contact us to find out how we can help you.

CUTTING OPENINGS IN LOADING WALLS

Work on the reconstruction of load-bearing walls should be carried out in ways that do not create significant dynamic loads. Nowadays, execution in panel and monolithic houses is carried out with diamond cutters (discs) in accordance with the requirements presented by design organizations. In this case, the cut out concrete wall fragment is cut into lifting parts weighing about 40 kg. Before cutting, if necessary, unloading racks-jacks are installed to transfer the bearing loads

REINFORCEMENT OF THE OPENING IN THE LOADING WALL

Reinforcement of the opening in the load-bearing wall. a prerequisite for the production of work. The need to strengthen the load-bearing elements of building structures arises as a result of increased loads caused by changes in part of the structure or premises. There are load calculations according to which the amplification scheme and metal specification are selected.

In each individual case, when it is necessary to make an opening in the load-bearing wall, an individual project is developed, including the obligatory calculation of the redistribution of loads on the variable part, taking into account the type and material of the structure, number of storeys, previous redevelopment works on the lower and upper floors. The work must be carried out strictly in the manner prescribed by the project documentation.

DELIVERY OF WORKS

In accordance with the decree of the Moscow government dated 25.10.2011 No. 508 “On the organization of the reconstruction or redevelopment of residential and non-residential premises in apartment buildings” after the opening, the reinforcement work must be handed over to the representative of the design organization that developed the reinforcement project.

We focus on redevelopment, reconstruction and modernization of the existing housing and commercial stock.

Cutting openings in Kiev

Diamond cutting of openings is one of the most popular ways to work with various types of walls. The popularity of this method is due to the fact that cutting openings without dust occurs at a high speed of work, no noise and high quality of work. Diamond cutting equipment is used both for capital construction and for minor repairs in an apartment. The main machine, which is often used for making holes, is the diamond cutting machine. Blades with diamond segments are used for cutting:

  • concrete;
  • fiber-reinforced concrete;
  • reinforced concrete;
  • bricks;
  • other artificial and mineral materials.

Our company will help in carrying out these works. Before starting the project, our professionals will inspect the work site and advise on where it is best to make an opening in the wall, taking into account the materials from which it is made. After the inspection has been carried out, a work project is drawn up.

Next, the holes are marked in the corners, and the workers proceed directly to dismantle it. To cut an opening in the ceiling, you need to spend about 3-5 hours of time. The provision of dismantling services is the main focus of our organization, therefore our employees have at their disposal all the necessary modern equipment. Thus, diamond cutting of openings, the price of which is negotiated in advance individually, is performed safely and without damaging the finish. The cost depends on taking into account some factors:

  • the material on which the work is carried out;
  • wall thickness;
  • the need for reinforcement;
  • reinforcement;
  • the need to remove garbage left after the end of work.

Punching openings with obsolete equipment has long faded into the background due to high vibration, low efficiency and high labor costs. But keep in mind that cutting openings in load-bearing walls, even with a diamond installation, is allowed only in certain types of houses and not anywhere. To perform such tasks, it is better to contact professionals who will determine whether it is possible to carry out the work.

Although making an opening in a load-bearing wall is not an easy task, since this procedure has certain difficulties, thanks to modern innovations, in particular, diamond cutting, it is possible to cut openings in walls and ceilings of virtually any thickness in the shortest possible time. Before cutting an opening in the wall, the price is negotiated in advance after inspecting the place of future work.

Arched doorway

Arched openings represent a design solution that visually divides the room, while making it more spacious. The arch can be pointed and round. Also, arches can be made of various materials: concrete, brick, plastic, wood and others. Increasing the opening for the arch will allow you to apply modern solutions in construction, visually increase the volume of the room and, in fact, improve lighting.

Our experts perform high-quality cutting from concrete, brick and other materials. Also, if necessary, reinforcement of doorways with metal structures is carried out and a project for future redevelopment is agreed. By contacting us, you can significantly save time and receive high-quality services.

How to cut a brick wall. How to trim brick by hand

A regular hacksaw or brick saw will not work. It will quickly become dull, and it will take too much time for each stone. Therefore, if you just need to reduce the size of the brick along a straight mowing line, use the splitting method.

To do this, you need a pencil, a building corner and a small building pickaxe.

For splitting, choose bricks without cracks and other visible defects. On them, with the help of a square, markings are applied along all the edges, and with the help of a sharp tool, a groove is made on one of them.

Then they turn the brick with a furrow down, take it in the left hand so that the greater half is in it, and with a sharp and strong blow of a pickaxe on the markings, they split it.

In this case, the tool should be strictly perpendicular to the brick surface. When struck at an angle, the chip is uneven. The same happens when the master holds the brick by the smaller half or in the place of the split.

The pictures show the sequence of work. The last picture is an example of a wrong grip and strike.

Note. This method is suitable for well-fired bricks. If it is not of the best quality, 5 mm deep grooves will have to be made on all edges.

Experienced craftsmen get by with one pickaxe and do not make grooves. But if this is your first time trying to divide bricks with your own hands, it is better to do everything according to the rules.

The manual method has disadvantages:

  • Low accuracy.
  • The split will not be perfectly flat anyway.

It takes experience and training to get an even chip.

Advice. If it cannot be left inside the masonry, you can gently beat off the protruding parts and rub the cut against another brick.

  • Brick can only be split at right angles.

  • Availability of pipes and fittings.

Is there a chimney, and where is it located?

Such information cannot be obtained by routine inspection; a metal detector must be used.

Tip: The detection of any obstacles does not mean that you cannot make a passage in the wall. In this case, it is necessary to properly prepare for the work.

To fix problems, when doing it yourself, you must:

  • Move electrical wiring to another location.
  • Step back from the chimney at least three meters.
  • To move the pipes, you need to invite a specialist. Preparation for work
  • Cut an opening in a capital wall: how to cut through

    First of all, it is necessary to calculate the doorway in the load-bearing wall, taking into account the following points:

  • Its dimensions are selected in accordance with SNIP or building codes. over, in the load-bearing wall:
  • the height should be no more than 2.1 meters;
  • width within 0.7. 2 meters. For an apartment located on the ground floor, the width of the opening cannot exceed 0.9 meters.
  • Optimal placement. center of the wall.
  • The top of the hole must match the cement joint of the masonry.
  • The opening must be arranged so that between the wall and the door frame there is a gap of 25 millimeters on the sides, and 6 on top.
  • Tip: An opening that is no more than 90 centimeters wide does not need to be reinforced further. With a greater width, the wall must be strengthened.

    Tools and materials for work Before transferring the passage, regardless of its purpose, for work you need to purchase the tools presented on

    To work you need tools:

  • angle grinder or hammer drill.
  • Locksmith chisel and hammer.
  • Triangle.
  • Building level.
  • High quality roulette. Materials required:
  • Wooden bars.
  • Reinforced concrete beams.
  • Steel corners or channels.
  • Cement mortar. Punching in the partition
  • Before making a doorway in a concrete wall or brickwork, you need to carefully consider the existing documentation for the house. It usually indicates all communications, the laying of the power supply system. In the place of planning the opening, holes are drilled.

    Punching passages is accompanied by a lot of dust. This requires special protective clothing:

  • Respirator.
  • Safety glasses.
  • Gloves.
  • Tip: To settle the resulting dust, the wall should be sprayed with water from a spray.

    Any opening is made in the shape of the letter “T”. A crossbar is mounted in the upper part, which will hold the brickwork. In the manufacture of the crossbar can be used from a regular wooden board. The load-bearing wall requires the installation of a reinforced concrete beam.

    The partition is usually made of small thickness, which makes it easier to punch a hole in it. The work instruction offers:

  • Use a square and a ruler to make the appropriate markings, taking into account that the opening should have a wider width than the door to be installed.
  • The section of the wall is freed from all types of finishing materials, up to brickwork.
  • Cleaning the surface from the finish

  • On the lines applied during the marking, cuts are made of an angle grinder with a disc with a diameter of more than 200 millimeters, on which there is a diamond dusting. Such cuts will become edging for the future opening.
  • Holes are drilled at the seams for laying bricks.
  • With the help of a chisel and a hammer, several bricks are knocked out.
  • Tip: The first brick should be knocked out with a rotary hammer drill. It can be replaced with a large diameter drill.

  • A hole is punched for the installation of the crossbar.
  • Wooden board inserted.
  • Crossbar for opening

  • Cement mortar is poured. This stage of making the opening cannot be ignored, otherwise cracks may appear in the wall. Opening in the supporting structure The cost of work for the supporting structure will be higher. In this case, punching the opening is performed with minor differences and includes the following stages:
  • The coating is removed before the brickwork.
  • How much does it cost to make an opening in a brick wall. Wall repair cost in 2019.

    How to cut a hole in a brick wall without dust. How to cut a doorway in a brick wall?

    Brick walls are most often found in houses of the old foundation. These are pre-war houses. Also, sometimes brick walls are found in country houses. Brick is not as durable material as some people think. It is obtained by firing clay with other materials. And, accordingly, it can break to crumble, undergo cracks. The most common mistake when working with masonry is haste. Brick requires careful and careful handling. Otherwise, you are guaranteed chips and other damage.

    The standard brick size is 25012065 millimeters. In construction, standard bricks are used to eliminate the possibility of uneven surfaces. The bricks are also laid one at a time, fastened to the cement mass. This process is time-consuming, but the strength of the structure being erected exceeds the strength of other types of masonry. Since the point nature of such a surface allows you to maintain the structure, even in the absence of one or more elements. In addition, the dismantled element can be easily replaced with a new one. This is the main advantage of brick walls. When building country houses, bricks of the m-75 and m-100 brands are usually used. Brand stands for power. For example, a brick of the m-75 brand can withstand a load of 75 kilograms per 1 square centimeter. Typically, load-bearing walls are laid with bricks in two rows and have a width of 240 millimeters, respectively. This is one fourth of a meter. Such walls are especially difficult to break, because the bricks are not stacked one after the other, but in a checkerboard pattern. It is no exaggeration to say that such a wall will stand for more than one century. Partitions between rooms are 60 millimeters wide, that is, half a brick (bricks are placed on their side). Such a partition, although less durable than a load-bearing brick wall, is more durable than a drywall wall, for example.

    How to make a niche in a brick wall. Niche in a brick wall. Purpose and features of surface selection

    • Niches in brick walls are often made not entirely with decorative intent, which does not negate such an opportunity as a whole.
    • Often the need for its creation is justified by the small dimensions of the premises. Only a dozen centimeters are not enough for furniture or household appliances to fall into place. And sometimes it is needed to hide heating radiators in the recess.

    Before you tackle the hammer drill and provide your neighbors with a few noisy hours, you should know this:

    • a niche in a brick wall is built to a depth of no more than 15 cm (this is half a brick);
    • the notch must be reinforced with a jumper on top;
    • it is important to make sure that the wall to be “retrofitted” is a thick load-bearing structure. For apartment buildings, the standard for its thickness is 40 cm. This is the surface in which the entrance door is located, the wall along the building and the outer foundations. It is better not to touch the latter, since they perform an important constructive function, and in addition to violating the integrity of a residential building, thermal insulation can also be damaged. Such interventions are considered illegal. Considering the above, there is only one target left for “improvements”. this is the wall in the center of the apartment. It is usually located along the corridor;

    Another fundamental point: regardless of the described standards for the location of walls in apartments of residential buildings, before carrying out work, it is imperative to check the plans of the builders.

    How to make an opening in a cinder block wall.

    Forum guest created a topic:

    In order to make the correct overlap of the window and door opening in a cinder-concrete building, it is necessary to use jumpers that meet the requirements of GOST 13015.0-83.
    Jumper types
    To cover the openings of windows and doors, ordinary reinforced concrete, steel lintels are used. Brick lintels are made in the form of an arched, arched, wedge-shaped floor.
    If jumpers are installed on a load-bearing wall, then it must withstand the load not only from the masonry above the window opening, but also the load from the floor slabs. Therefore, a reinforcing row is installed on the load-bearing walls made of cinder block, which takes all the load on itself.
    Lintels installed on non-bearing walls take the load only from the above masonry. Here, they mainly use bar lintels, having a width equal to the width of the block of the erected wall.
    For cinder block buildings, bar or slab reinforced concrete lintels are mainly used. The length of the lintel for non-load-bearing walls must exceed the opening on both sides by 120 mm, and lintels to be installed on the load-bearing walls must exceed the opening length by 250 mm. If the jumper block is longer than this size, then it will be necessary to deepen the landing socket in the wall for the block. The width of any lintel must match the width of the wall on which it will be installed.
    Facade lintels
    Usually, the PF beam for the front lintel is lowered below the main carrier by one brick. This is done in order to create a quarter for further fastening of the window block. For the front lintel, you can use a corner with a shelf of 100 mm. Lay the corner so that the vertical side of the shelf is on the inside of the facing row and is located in front of the backing masonry. It is important: that the plane of the edge of the installed corner is flush with the back side of the facing brick. That is, when a metal-plastic window is installed, it will have to enter close to a quarter of the window together with a corner.
    Reinforced concrete lintels
    On-site fabrication of reinforced concrete lintels is easier and more economical. Before installing the lintel formwork, it is necessary to fill the voids with the mortar of the block on which the lintel will rest. Then you need to put two solid bricks on the mortar. This will strengthen the anchor point for the jumper.
    Now we install the bottom of the formwork for the lintel, for this we take a board with a thickness of at least 20 mm, preferably having a width equal to the width of the wall. We fix it flush with the backing masonry block. From below, the shield is supported by installed supports, which must be very strong in order to withstand the power load of the poured concrete and the reinforcing row. The side shield, using self-tapping screws and a screwdriver, is attached to the side of the horizontal shield.
    Now, every 30 cm, screw the self-tapping screws into the side of the shield. Using a knitting wire, we fix the upper part of the side shield for self-tapping screws and for the reinforcing mesh of the facing row.
    We put reinforcing material at the bottom of the resulting formwork. For reinforcement, is a reinforcement having a section diameter? 14-15 mm. The fittings are laid in 3-4 rows in width and in 2 rows in height. The rows are connected with anchor pins from the same reinforcement, welding them together with a step of 20 cm.
    Now it is necessary to lay an insulating material between the facing wall and the backing masonry. It is advisable to lay the sides in these places with solid bricks. Then we fix the pumpan insulation on top.
    Pour the solution into the formwork by 2-3 cm. We put the support blocks from the scraps of reinforcement for the reinforcing structure and after its installation, fill in the entire required volume. The width of the reinforced concrete lintel should be equal to the height of the masonry block. The result should be a flat surface of the lintel and a row of masonry.
    The side formwork can be removed after 2 weeks. The lower formwork panel is removed not earlier than after 35 days.

    Diamond wall cutting technology: advantages and application features

    Today, diamond cutting of walls is considered the most advanced technology. With its use, dismantling work, revision of the layout and cutting of openings in the walls of residential and utility premises are carried out. By combining the interior design in various ways, an experienced craftsman can work with material of almost any thickness and strength, regardless of the degree of its reinforcement. Let’s dwell on the features of this technology and the options for using devices of various classes. In the video. work on a load-bearing wall:

    hole, wall, dust

    Sequence of work

    Before making holes in the concrete with your own hands, you need to make sure that this does not compromise the strength of the building. Bearing walls can only be cut after consultation with specialists.

    Redevelopment works are carried out in the following sequence:

    • decide on the size of the opening;
    • cover household items with foil;
    • dismantle a used door or window;
    • wear safety glasses, gloves and a hard hat;
    • connect the tool and cut the opening of the given configuration.

    The cut edges after diamond cutting are smooth and do not need additional processing.

    How To Catch Dust When Drilling

    Strengthening window openings

    Since the windows are installed in load-bearing walls, any change in the configuration of the opening entails a weakening of their bearing capacity. An emergency situation can be prevented by reinforcing the cut made. This event is held immediately after the dismantling of the window sill block is completed. Competent strengthening of the opening allows not only to preserve, but also to increase the bearing capacity of the wall.

    Cutting openings in the floor

    In the process of redeveloping an apartment or for carrying out communications, it may be necessary to cut a hole in the floor. Depending on the conditions of the project, openings are made of rectangular or round shape. For this, a diamond cutter or drill rig with a large diameter diamond core bit is used. The part of the floor to be removed is divided into segments, which are pre-fixed before final cutting and extraction.

    Types of openings

    Diamond cutting of walls allows you to cut holes of this shape:

    • square;
    • rectangular;
    • round;
    • oval;
    • arched.

    With the help of diamond equipment, openings are made in walls and floors, at right angles and inclination.

    Expanding wall openings

    Expansion of openings in load-bearing walls is done in cases when it becomes necessary to increase the area of ​​windows or to put a large entrance door. Depending on the thickness of the wall, cutting is done from one or both sides. When performing work on the lower levels of multi-storey buildings, cutting is carried out only after preliminary strengthening of the structure.

    Brick wall cutting

    Drilling holes in a brick wall must be carried out with a minimum vibration amplitude. From the concussion, the masonry is destroyed. To prevent this, it is necessary to use diamond-coated bits and discs, since clay bricks are highly durable. Before cutting an opening or making a large hole, it is advisable to reinforce the wall. For this, a lintel made of steel or reinforced concrete is used. It is inserted and glued into a pre-made niche cut with a diamond disc.
