How to cut fiberglass reinforcement

Before filling the foundation, you need to correctly knit reinforcement for greater strength and stability of the structure. This allows you to tie the reinforcement into a single design, thereby creating a supporting frame of the building. The power of the total foundation design must be provided with additional stiffeners. This will need:

Important! The knitting wire should be a round section, you should not take a square, since when twisting, the wire can damage itself. There are several types of hooks for knitting:

There are several types of hooks for knitting:

The named materials must be chosen very carefully. For example, the knitting wire should be quite thick to avoid its ruptures when the concrete is supplied to the frame. Otherwise, the ligaments may burst, and the design of the strip base will turn out asymmetric, which cannot be allowed in any way.

The transverse rods of the lower layer are laid on the reinforcing fixers, which are installed before work. Shared rods are cut and laid at the distance required from each other, they are noted on them. At right angles to shared rods, jumpers are installed, each of which is connected in the marked places. If the knitting is carried out with wire, then it must be folded in half and firmly fixed with a hook. If clamps are used, then each of them is tightened more. After completing work on the construction of the first row of the grid, you can make the rest of the frame. Perpendicular segments are attached from the inside of the cells in the same way.

Particularly carefully need to approach the strapping of the corners. In construction stores you can buy special elements that are easily installed in the place of angles

Important! In the corners, the reinforcement can only be knitted manually, without thermal exposure. The finished frame is laid in the formwork in the horizontal position of the nets

The finished frame is laid in the formwork in the horizontal position of the nets.

This method is very common among the builders with whom the knitting of the reinforcement is carried out with their own hands. In addition to him, there are several more options for fastening the reinforcement for the strip foundation:

Important! Before starting work, you need to clearly determine which loads are planned for the strip foundation, and what is the volume of work. This is interesting: ideas for painting walls with water.based paint. we set forth in order

How to make a reliable frame for the foundation

In order to correctly make the basis for the strip foundation for which fiberglass reinforcement will be used, you can watch the training video and use simple recommendations. So, the algorithm for manufacturing such a frame looks as follows.

Before knitting reinforcement, you need to draw up a drawing of your future frame and cut all the elements for its manufacture in the exact sizes. The transverse rods of the lower layer of the reinforcing cage are positioned using special latches. Such elements can be installed both before the start of the assembly of the reinforcing frame, having previously measured the size of its cells, and after its readiness. The size of the cells depends primarily on the size of the strip foundation that you are going to strengthen. This size can vary wide enough: 15-30 cm. The longitudinal rods of the reinforcing skeleton before knitting, it is better to pre.lay out on the ground and make markers in those places where transverse elements will be fixed on them. Starting to knit reinforcement, you should ensure that the elements are fixed with each other strictly at right angles. The transverse jumpers should be knitted with longitudinal elements of the frame on their bottom. In order for the reinforcing skeleton and, accordingly, the future foundation turns out reliable and stable, plastic clamps or knitting wire in places of joints should be knitted. The horizontal layers of the reinforcing frame are originally made, only then you should knit them with vertical jumper

It is also necessary to fix vertical jumpers on the inside of the frame cells, this will allow you to get a reliable and stable design that will not be separated in the process of pouring concrete and will perfectly perform your reinforcing functions. Corners are a special place of the reinforcing structure, and they need to pay separate attention. Fiberglass reinforcement is not recommended to bend on its own under the influence of heating, which can most negatively affect its strength characteristics

Therefore, the corner elements of the reinforcing skeleton are best knitted from the already bent rods that can be purchased today, or carefully perform a bend without thermal exposure. After the reinforcing structure is completely ready, it must be carefully placed in the inside of the already prepared formwork.

If you knit elements of the reinforcing frame using wire, then to facilitate your work you can make a knitting hook, for which it is convenient to use the old screwdriver. How to make such a hook and knit with it a reinforcing cage, you can also familiarize yourself with the corresponding video.

The manufacture of a reinforcing frame of rods made of fiberglass is a simple process, which can be judged even by a training video, where it is shown in detail how to knit it. To work with a material such as fiberglass, you will not need special tools and complex equipment, it is easy to cut and knit, it has an easier weight than the reinforcement made of metal.

The history of the appearance of fiberglass reinforcement in construction

Fiberglass reinforcement is actually not a novelty in the construction market, it was developed and began to be produced back in the 60s of the last century. However, its high cost at the time of the start of production contributed to the fact that it was used to reinforce only those structures in which steel strengthening elements were actively corrosion: concrete structures operated in harsh climatic conditions, bridges and others supports, etc.

Fiberglass reinforcement will be the best solution for the construction of concrete structures in contact with sea water

The active development of the chemical industry led to the fact that over time, the cost of production of fiberglass reinforcement has decreased significantly, which made it possible to start using it more actively. The widespread use of this material was also facilitated by the fact that in 2012 the state standard (31938-2012) was approved, according to which the requirements not only for production, but also for testing of fiberglass reinforcement were determined.

According to the requirements of the above regulatory document, the fittings made of fiberglass materials can be available in the diameter interval of 4 to 32 mm. But the greatest use, especially in low.rise construction, acquired products whose diameter is 6, 8 and 10 mm. Unlike similar steel products, fiberglass reinforcement is released to the customer not in the form of separate rods, but wound in the bay.

Armature SP: comfortable, light, stable and elastic

In the normative document, in addition to the technical characteristics of fiberglass reinforcement, the requirements for the state of its outer surface are stipulated. According to these requirements, on the surface of such products it is not allowed to have chips, relaxation, dents and other defects.

How to cut fiberglass reinforcement?

On the one hand, if we talk just about all possible options, then composite fiberglass reinforcement can be cut in different ways:

Bite with a bolt cutter; Cut off an ax; Cut with a hacksaw for metal; Cut an angle grinding machine (“corner grinding”).

But the most correct option of all listed above is the use of “corner grinding” with ordinary abrasive or diamond circle. The fact is that the first two methods cause a strong impact on the adjacent areas of the reinforcing rod, leading to its deformation, painting and splitting in these areas. Thus, the adjacent ends of the reinforcing rod will be very split, approximately, as shown in the photo on the right (click on it for viewing in full). Do not be alarmed, in fact, a segment of composite reinforcement is depicted in this photo, destroyed as a result of the compression test, but the nature of the destruction of the edge in the form of longitudinal cracking is the same as when sniffing the composite reinforcement or cutting with an ax. Such breakdown is extremely undesirable, since the resulting cracks can be invisible to the naked eye, but to go quite deeply into the body of a reinforcing rod. Such cracks in the body of the core of composite reinforcement will be capillary channels to get into the water rod, alkalis when pouring concrete. In the first case, there is a danger of further development of cracks due to the cycles of freezing and thawing. In the second case, the destructive effect of the alkaline environment of concrete on the reinforcing rod is aggravated (now this effect is not only outside, but also from the inside). We draw your attention to the fact that before cutting fiberglass reinforcement. take care of protecting the eyes, hands and respiratory organs. over, pay special attention to the latter! Do not forget that you are going to cut glass or basalt fibers and the dust formed will be a completely unnecessary guest in your lungs! You can protect yourself from this dust using a respirator. But remember that the respirator should fit tightly to the face, excluding the possibility of inhalation of dust bypassing the filter element. To protect the hands from thin, almost invisible splinter in the form of glass or basalt fibers, having a thickness comparable to the thickness of the human hair, to use ordinary x/w gloves is not suitable! You will need the so.called “awake” gloves or at least m/a gloves with a continuous layer of PVC or latex applied to their inside.

Cutting composite reinforcement with a hacksaw for metal

Pros of cutting fiberglass reinforcement with a hacksaw for metal

The optimal combination we consider the presence and use of an angular grinder and bolt cutter. “Corner grinder” cut the main part of the volume, and trim the “tails” with a bolt cutter. (Of course, if there is electricity on the site).

How can you cut fiberglass reinforcement?

Composite glass.plastic reinforcement is a material that can be cut in different ways. Such reinforcement is often used in construction in both abroad. One of the main methods of cutting fiberglass reinforcement are:

• Cut off with reinforcing scissors (bolt cutter);
• chopping off with an ax;
• sprinkling with a hacksaw for metal;
• Cutting an angle grinding machine (corner grinding).

Choosing the best option of all of the above, it is worth giving preference to a corner grinder with a detachable circle. As for all other options, the first 2 are bad for cutting the reinforcement, as they will have a great influence on the adjacent parts of the material, deforming its edges. Cutting with an ax, the use of bolt cutter or hacksaw for metal can leave almost inconspicuous cracks in the material, which will go deep into the body of the reinforcement.

Important! Cracks that have arisen in the process of sawing or cutting off, become channels into which water and alkali falls. When water enters the microcracks, there is a probability of increasing cracks in size. This is due to the process of freezing and thawing. In addition, the alkali, which is contained in concrete, penetrates the rod inside and destroys the reinforcement from the inside. Thus, the best way to cut fiberglass reinforcement is using a corner grinder. This tool minimally damages the edges of the material, while the pruning process will be as fast as possible. You can buy composite reinforcement and in the region right now with the help of our site. The price of our reinforcement will pleasantly please you.

note! If you are going to cut fiberglass reinforcement, it is worth taking care of protecting the eyes, limbs and respiratory organs. It is worth remembering that in the process of cutting fibers, dust can be created, which negatively affects the respiratory system of a person. In this case, it is necessary to use a respirator. Pay attention to him to fit well. Pay attention also to protect the hands and body. Thin fibers of basalt or other materials can easily penetrate under the skin during operation. You can protect against this with gloves that have a continuous layer of PVF and latex.

To the question: where I will buy high.quality materials for construction, we offer profitable solutions at affordable prices.

Types of reinforcement and how to cut it quickly

The secret is simple. it is the combination of reinforcement with concrete that allow you to create very strong structures, and a large selection of core reinforcement allows you to choose metal for “your” construction task.

The ability to purchase a rod of various shapes and sections at a favorable price is offered by the company “Metal Stroy Region”. You can buy metal rolling in our company in any volumes, deliveries are carried out in the software and Moscow. After all, the pace of construction depends on the timeliness of the transportation of materials, so any delay is fraught with “force majeure”. Reinforcing rods and rods are produced by various lengths, as the nomenclature requires. The reinforcement with a diameter of less than 10 mm is supplied in skeins if the diameter is above 10 mm. the rods are brought in rods of various lengths. Here the main catch is “hiding”. in construction work, the use of reinforcement is practically not necessary, and the reinforcement is necessary for each task is necessary.

How to cut reinforcement?. the use of high.quality and professional tools allows you to reduce the time of work by an order of magnitude. If we are talking about a small amount of reinforcement with a diameter of 8-10 mm, it is enough to use reinforcing nippers (another name bolt cutter or reinforcing scissors). Due to the double lever, the efforts attached are doubled, respectively, the workflow is “more fun”. Another “win-win” version of high-quality and fast cutting is if the reinforcement diameter is more than 12 mm and its physical and mechanical properties are characterized by high strength, an angular grinder is used (corner grinder)

Important! Nobody canceled the safety rules, and when cutting the reinforcement with a corner grinder, several “axiom” should be clearly held: protective glasses, gloves, reinforcing rod should be raised above the ground and reliably fixed. As a rule, when cutting long reinforcement, an assistant is necessary

What are the advantages of this method. a corner grinder can be used literally everywhere, minimal skills are enough, cutting of the reinforcement is performed quickly. One of the most convenient, fast and safe methods of cutting reinforcement, which is used on an industrial scale is the so.called “guillotine” (electric end saw).

The company “Metal Stroy Region”, offering a reinforcement, the price for which is located on the site, uses just such professional equipment for cutting metal rolling to the size of customers. The use of guillotine allows you to quickly, efficiently and carefully process a large batch of metal rolling in a record time. Economic “pluses”. it is not required to use long.range cars for transporting long rods, when the already cut reinforcement is cut the desired length to the construction site, builders immediately start work.

The principle of guillotine operation. pre.marked reinforcement is installed on the base, cut off by a lowered disk and extended to the next mark. Quickly, efficiently and neatly, without the slightest deviation from the given sizes. the use of guillotine allows you to cut the reinforcement of any profile and any thickness. Due to the increasing popularity of reinforcement as material in the construction market, our company has significantly expanded the range.

The proposed reinforcement, the price of which is indicated on our website, will be delivered as clearly agreed terms. Each party is necessarily accompanied by certificates, because reputation is just a concept that “you can’t buy for money”, and the quality control of our products is carried out by the company’s specialists more than strictly. Timely delivery of software and mo, the ability to order any batch of metal rolling, cutting metal to the dimensions of the customer, the quality and breadth of choice. to cooperate with the “metal system of the region” is easy, convenient and profitable.

We make clamps

The most common way to knit the reinforcing cage in the manufacture of strip foundations, columns, beams and crossbars is the use of clamps that allow you to protect the reinforcement from displacement when laying concrete. The step of installation of clamps is 30-50 cm, so there will be a lot of them. over, they should be the same in shape and size.

The wire must first be cut into pieces equal in length perimeter of the clamp plus 10 cm. If the wire is curtailed in the bay, it is convenient to make a semicircular template in the shape of a bay from the first segment and cut the remaining pieces of wire without unwinding it. The resulting curved pieces of wire must be straightened with a hammer on a wooden bar.

Cutting when buying

If you buy reinforcement in a store or in a small number, ask the workers to cut it into segments of the length you need right there. Usually, many sellers provide such a service (paid or free), trying to lure as many buyers as possible, since cutting the reinforcement in this way is much more profitable:

• You do not have to look for a car and transport long rods of reinforcement;
• The reinforcement at your construction site will arrive already cut into parts of the desired length, and you can immediately start working with it;
• You do not need to cut the reinforcement yourself and look for the necessary tool for this.

Just do not forget to calculate the quantity and length of the reinforcing rods you need in advance.

How can you cut composite reinforcement

One of the main advantages of composite reinforcement is the simplicity of its cutting. Cutting fiberglass reinforcement is carried out directly at the place of work, which significantly reduces the construction time. To cut the rods in size, use the following tools:

Consider the advantages and disadvantages of each tool.

Angle.grinding machine

When the question arises, how to cut fiberglass reinforcement for the foundation (we already wrote more about the material itself here), builders primarily recall the corner grinder. This tool allows you to cut a large amount of material with qualitatively, quickly and with minimal effort.

The advantages of using an angle grinding machine include:

• high speed of work;
• With the help of corner grinder, you can immediately cut a bunch of rods;
• Mechanized cutting does not require large muscle strength;
• the possibility of using disks with any cutting edge (for metal or stone).

Before cutting fiberglass reinforcement with a corner grinder, you need to take into account the minuses of work with this tool:

• cut fiberglass with a corner grinder without dust, it will not work. The high speed of the disk leads to the spraying of small particles of fiberglass in the air. Air vanity for cooling the tool of the tool contributes to the even greater spread of composite dust. Therefore, when working with an angle grinding machine, you need to use the means of protecting the eyes and respiratory organs, especially if you have to saw the reinforcement in the room;
• For the operation of a corner grinder, you must have an electricity connection point.

Kryazuvka for metal

If only a few cuts have to be performed, you can use the usual hacksaw for metal.

The use of a manual tool gives the following advantages:

• The metal hacksaw is found in every owner. This is the easiest and cheapest way to cut a small amount of rods for a bunch of reinforcing frame;
• Lack of spraying small particles, as in the case of angular grinder.

Negative moments of the use of hacksaw for metal for cutting composite reinforcement:

• low speed of work;
• high load on the employee, if it is necessary to perform a large amount of work;
• the possibility of use only in individual construction for small volumes of work.

Boltorez

Before cutting composite reinforcement using bolt cutter, you should also study the pros and cons of working with this tool. You need to understand that boltores does not cut a composite bar, but rather a snack, which affects the technical characteristics of the material.

Advantages of using bolt cutter:

• no connection to the mains is required;
• When working, a large number of small particles is not formed by a bolt cutter, so you can prepare rods in size indoors;
• You can move and work anywhere with a bolt cutter in your hands (there are no wires).

Disadvantages of the use of bolt cutter:

• With the help of bolt cutter, more than 3 rods cannot be cut at the same time;
• When working with this tool, it is necessary to use significant muscle efforts;
• Boltoresis is rarely in the list of home tools. To work, he will have to rent or buy, which is economically impractical;
• The use of bolt cutter causes deformation of the material at the site of the cut (at the end of the rod there are crumbs of material and longitudinal cracks). Such deformation reduces the bearing capacity of the reinforcement, and reduces its service life.

Axe

With limited means, an ax can be used to prepare reinforcement. He, like boltores, cuts off the bar, which affects the condition of the reinforcement at the place of the breakdown.

• Any owner has an ax. It is not required to separate the tool separately;
• speed. When preparing the basis for cutting reinforcement, you can perform work quite quickly.
• The inaccuracy of the cut. Not every master can accurately and strongly get an ax to the right place to cut a composite bar;
• Deformation of the tip of the rod. During operation, water, cement, alkali can fall into longitudinal cracks, which will lead to a violation of the technical characteristics of fiberglass and weakening the entire structure. With changes in temperature, split reinforcement inside the product will change in volume, which will lead to the destruction of concrete.

How to cut fiberglass reinforcement

Unsable production is one of the main advantages of composite reinforcement. Unlike metal, it can be easily cut into pieces of the desired length and use them without a residue.

How to saw reinforcement:
• corner grinder. One disk is enough for cutting with a machine
• Kusachki if the reinforcement has a small diameter
• scabbard for cutting metal

How to connect composite reinforcement

Fiberglass reinforcement is associated not only with each other, but also with metal rods. How to do it? Most often for this purpose, knitting wire of millimeter thickness is used. With large volumes of work, it is convenient to bind the rods with wire with a special manual or electric tool. The knitting hook is used for medium volumes of work. If you need to tie a small number of rods, you can do without auxiliary devices and perform work manually.

To knit reinforcement, brackets and plastic clamps are also used. Note that the method of binding the rods is not of fundamental value. The main goal of the procedure is to fix the rods in the right position before pouring concrete. As soon as the concrete froze, the rods will no longer budge. However, wire or other binding material should be quite thick and durable. this will ensure the integrity of the frame when the concrete is submitted.
