Plastic fittings: reviews. Plastic reinforcement for the foundation: reviews. Application and characteristics of plastic fittings

Fiberglass reinforcement is a building material created on the basis of complex fibers. It is made on the basis of basalt, glass and carbon fiber, and they can be combined. However, the most popular are basalt-plastic reinforcement and fiberglass.

What is made of?

It can be divided into two parts. The first is the trunk, due to which high material strength is achieved. The fibers are bonded together by the polyester resin of the composite. The outer layer serves for reliable adhesion to concrete: this fibrous body, which is wound around the trunk in a spiral. It is thanks to this composition that the plastic fittings reviews received positive as a reliable material for construction. There are various variations of the reinforcement models, some of them quite unusual. For the production of this building fittings, fiberglass is used. Its peculiarity is that there are practically no analogues in the world, and positive qualities significantly expand the scope of application. In addition, this material is modern and effective, and therefore as best as possible meets the requirements of the construction process.

At the heart of any fiberglass reinforcement are two components. The first is directly reinforcing material, the second is a binder (a mixture based on epoxy resin). The ratio of these components is 75 to 25. In composite reinforcement, all mechanical loads fall on the reinforcing component, while the binding materials are a kind of matrix that evenly distributes the load to the entire length of the rod and protects it from external influences.

The most common recipe can be considered the following: as a reinforcing link are glass-roving or basalt fiber, for the use of epoxy resin, in addition, the composition of the material will include a hardener and an accelerator. However, the universal composition does not exist, because each manufacturer builds its own technological process.

What is the secret of popularity?

It must be said that compared with metal materials, plastic products are in demand much more today. And plastic reinforcement is used in any construction process. This is achieved through several qualities:

1. Resistance to corrosion, aggressive environment, including alkaline environment of concrete. Unlike metal, plastic does not rust and does not collapse. These qualities contribute to the fact that plastic structures are widely used in equipping berths, fencing structures on water bodies.
2. Reliability and durability, which plastic products have more than steel. It is reliability that makes it possible to use them when building structures of various purposes and volumes.
3. High tensile strength.
4. Lightness of the reinforcement: for example, compared with the steel variety, plastic is five times smaller in weight and 11 times smaller in diameter. Such indicators indicate that you can save on construction work, as well as on the transport of material to the facility.
5. Low thermal conductivity, due to which the room does not penetrate the cold. It is no accident that plastic reinforcement for the foundation is increasingly used: when it is erected it is possible to achieve high energy efficiency due to economical materials.
6. Resistant to radio waves.
7. Possibilities of application in various temperature modes: from -70 to +100 degrees.
8. Cost: to buy a running meter of plastic fittings will be much cheaper compared, for example, with a piece of one meter of metal rod.

Features of composite fiberglass

Composite fiberglass reinforcement appeared on the domestic market not so long ago and today it is considered a new technology. Such plastic fittings reviews also received good, because it has a number of advantages over metallic analogs. Firstly, such structures have a low weight, so the foundation will not be too heavy, which means that the building will last much longer. Secondly, due to the high tensile strength, such reinforcement can be used to erect objects that are complex in terms of design features. Thirdly, the composite material is resistant to an aggressive environment and does not conduct an electric current.

On the other hand, the composite plastic reinforcement has a weaker modulus of elasticity compared to steel products. Especially strong elasticity is lost when heated to 600 degrees of the composite. But on the other hand, it is this characteristic that speaks in favor of the fact that the plastic reinforcement has been applied to the installation of the foundation, where the tensile strength is very important.

Where do you need composites?

SNiPy and other rules recommend the use of composite reinforcement in the following works:

1. In slabs: as a rule, the reinforcement is placed in the upper or lower zone of concrete, while the concrete class should be B25.
2. When reinforcing structures made of concrete and reinforced concrete.
3. When erecting foundations that have a zero mark of occurrence.
4. In reinforced structures that are subject to the influence of an aggressive environment.
5. In the repair work associated with damage to concrete due to the influence of aggressive media.
6. For reinforcing brickwork, especially if it is performed in winter.

Where is the fiberglass reinforcement used?

The scope of this building material is extensive:

1. For foundation installation. In view of the tensile strength, it is advisable to use GRP specifically for erecting a base for objects. First, the installation will be simple. Secondly, the foundation will be strong. Plastic reinforcement for the foundation reviews get positive thanks to the fact that it allows you to create a monolithic foundation. It is placed directly in the concrete solution during the pouring process, so that the bonding of the materials becomes stronger. To prevent the formation of pores and cavities at the junction, specialists use special vibration equipment.
2. When equipping a high voltage power line. Since the material does not conduct current, the energy will be lost minimally, while its operation will be safe.
3. Plastic reinforcement builder feedback gets positive due to its versatility. So, it can be used to strengthen the strength of the roadway, supports, bridges.
4. Composite materials underlie the production of sleepers. Because of the intense vibration, under the influence of which the concrete breaks down, a new material was needed, and the fiberglass reinforcement became a correct and effective solution.
5. The metal is not resistant to aggressive media, high humidity, solvents and acids, respectively, the life of its not very large. Fiberglass, used in the construction of docks, quays, various fences on the shoreline, shows the best performance.
6. Used plastic fittings and in the equipment of mines with a special mesh, which protects the walls and vaults of the mine from caving and fixes them.
7. Do not do without this material and when fixing the insulation or facing material on the finished wall.

Varieties of fiberglass reinforcement

Plastic fittings in construction today are used increasingly, which is due to its unique characteristics. In addition, today we mean a number of nonmetallic structures under the composite reinforcement, which significantly expand the scope of their application. So, modern manufacturers offer fiberglass and basalt plastic reinforcement. At the same time, a variety of substances can act as polymer resins that bind fibers, each of which has its own characteristics.

Any building material is used on the basis of certain rules and requirements. Concerning this and the composite reinforcement. Plastic fittings, the characteristics of which are so diverse, is used in construction on the basis of SNiP, approved in 2003. By the way, each kind of material is controlled by the manufacturer, and therefore the armature must necessarily correspond to the parameters that were declared initially.

Fittings for the foundation: how to choose?

Today in private housing construction, plastic reinforcement for the foundation is increasingly used. Experts advise, when choosing it, to contact the official dealers and reliable manufacturers, as the strength and durability of the building as a whole will depend on the quality of the material. An important role is played by the quality of the product, as well as the density of the winding of the glass winding along the entire length of the rod. The coils should also be filled with quality. Materials of good quality - this is the most optimal choice for equipping any foundation - plate, tape or columnar. The choice of type follows, depending on what the bearing capacity of the soil, as well as the load on the building as a whole.

Reinforcement of the foundation is necessary in order to make the load on the foundation of the building more even during operation. Concrete has a compressive strength, but its structural integrity can be disturbed by the stresses. It is with the help of reinforcement and more adhesion to concrete, respectively, the foundation becomes stronger and more reliable. The main requirements for the selection of fittings are the following:

• Providing rigid adhesion to concrete;
• durability;
• flexibility;
• Resistance to rust and corrosion.

The armature can be working, that is, reducing stress and external loads, as well as distributing, when the load is evenly distributed to each rod - this helps maintain the correct arrangement of the working rods. With the help of clamps, the rods are connected to the frame, protecting the concrete from cracking. The transverse rods are protected from the occurrence of inclined cracks in the foundation, and longitudinal - from the vertical.

Plate foundation

When erecting this type of base, you need a reinforcement with a ribbed surface with a diameter of at least 10 mm. It is the diameter that affects how strong the reinforcement will be. Plastic reinforcement for the foundation, the reviews about which are so good, should be selected depending on the type of soil. Suppose, on a non-poppy and dense, that is, with good bearing capacity and resistance to deformations, the thickness and diameter can be small. If the house is massive, but on a weak ground, the reinforcement should be thicker - about 14-16 mm. With this option, the reinforcement of the plate will be upper and lower, and the total number of bars is more than 100. Viscous Can be performed in several ways. For example, first the bars of the reinforcement can be joined in the lower belt longitudinally and transversely, then vertical bars are attached to them, then again laterally and longitudinally. When tying fiberglass reinforcement it makes sense to use clamps and ties from plastic. This is the so-called viscous reinforcement plastic clamps.

Ribbon foundation

As a rule, the tape base has a height greater than the width. Accordingly, the tape at the expense of a small size differs tendency to bend, and therefore when building such a foundation it is possible to use reinforcement with a smaller diameter. The peculiarity of this basis is that two reinforcement belts will be needed, regardless of what its height will be. The process of laying the reinforcement will be as follows: in the upper and lower part of the foundation, at a distance of up to 5 cm from the surface of the concrete, rods are laid longitudinally - they will have all the load in case of deformation. Reinforcement in several bars can be used for weak or mobile soil, as well as when erecting oversized houses. The fiberglass reinforcement is ideal for the erection of a foundation foundation - grades f6 and f7 (for houses in one floor), marks f8 and f10 - for residential objects with an attic or in two floors.

Column foundation

Good plastic fittings (reviews confirm this) and when constructing this design. When reinforcing the columns, metal fittings with a diameter of 10 mm or fiberglass f6 are useful. As vertical bars it is better to choose a reinforcement with a ribbed surface, and horizontal ones are only needed to bind the rods into a single frame. The reinforcement frame is 2-4 bars long with the height of the post. For example, when reinforcing a pole with a height of 2 meters and a diameter of 20 cm, four bars of f6 will be needed. They need to be placed 10 cm apart, and also to bandage them with smooth reinforcement with a diameter of φ4 or φ5. For any type of foundation, you will also need an armature for plastic pipes.

Features of mating reinforcement

The foundation is an important component of any building, its quality and reliability is a guarantee that it will last a long time and will serve reliably. The reinforcement of the base must be approached wisely. Let's consider, how the binding of plastic armature for a tape base is carried out, as it is applied most often in a private house-building. The mating is necessary in order to make the construction of the reinforcing cage one and more durable. Bars are connected in the places where they intersect. A piece of wire bends in the middle, then it is put on a special hook, which is applied to the armature and tightened. An easier way of knitting involves the use of plastic ties.

When creating a reinforcement system, a plastic shut-off valve is important. Its main function is to promote a more durable and reliable fixing of plastic rods to each other. The most popular items in this regard are fixators, which are special mortgage details and contribute to the creation of a protective layer with a certain thickness in concrete. The retainer for the plastic fittings is created by the high-pressure polyethylene casting method. They are needed in order to reliably fix in the space reinforcing bars, frames, which will provide a protective layer in a concrete or reinforced concrete structure. Lockers can be designed for horizontal and vertical surfaces, as well as for creating formwork.

How is the plastic armature made?

Deciding to build your house, pay attention to a lot of small things and start with the construction of the foundation. Many are interested in the question of where to buy plastic fittings. Experts advise to address to the checked up companies as from the basis of the house, its quality and reliability depends service life of the construction. Equipment for the production of fittings is quite expensive, the quality of materials depends on its quality.

Plastic fittings, which are manufactured on high-tech equipment, can be produced in different diameters - 4-24 mm. Depending on the type of line, a different number of bars will be produced, as well as different cross-sections. Typically, the delivery package includes a number of devices - from the device for heating the threads and the impregnating bath to the drawer and the control cabinet. Thus, the equipment for plastic fittings should be selected correctly in order to make the technological process efficient.

Plastic fittings: customer reviews

In their reviews, builders - experienced and not very - agree on one thing: for the installation of a foundation, plastic fittings are just perfect. For example, some used a combination of steel and plastic rods: base plates and basement walls were created on the basis of plastic, and overlapping, where stronger materials are needed, were built on the basis of steel. Mark many and the convenience of knitting in comparison with the metal armature, which is supplied by one rod. By the degree of tensile strength and resistance to decay, there is also no better than plastic reinforcement.

But, on the other hand, it does not do without negative reviews. True, judging by them, these shortcomings are more than offset by merits. For example, there is an opinion that after the work with fiberglass, hands are scratched. In addition, to bend it to produce, for example, angles in the form of letters G or P is almost impossible. In this case, the manufacturers themselves focus on the fact that fiberglass reinforcement should be used exclusively for the installation of the foundation.

Steel or plastic: what to choose

For a beginner in construction, the choice of materials is always an important issue. For example, when decorating a foundation, it is important to perform a competent binding of the reinforcement. Of course, in the case of the construction of a bath you can use simple metal rods, but what to choose for a good house? Today, a choice is offered between steel and plastic structures, each of which has its own distinctive features and disadvantages. If we talk about the merits, then they can be reduced to the following points:

Apparently, the advantages of the plastic variety are still greater. The disadvantages of steel are: the occurrence of corrosion and a large weight of the structure, while the plastic reinforcement is only difficult in terms of performing bending. Thus, the technical characteristics of fiberglass reinforcement in no way inferior to steel, while it is cheaper. On the other hand, it is very important to remember the peculiarities of the construction of a particular house. For example, if you want to join the lining material and the wall, you can use a plastic-based fixture. But with the equipment of concrete floors with reinforcement, it is better to use metal structures, because in view of their high weight they will not surface when pouring concrete. Thus, when choosing the structures for reinforcement, several factors should be taken into account at once, which means that it is better to use the professional help of specialists.
