Regardless of purpose, each building needs preliminary design and creating a rather strong foundation. The implementation of this structure of the structure is impossible without the use of reinforcement. With the help of it, you can qualitatively strengthen the reinforced concrete structure, as it takes on the entire load.
The reinforcement is necessary not only to make the foundation more durable and reliable, but also to bind its individual elements. It is necessary to approach the choice of this material with all responsibility. Let us consider in more detail what should be taken into account in the process of choosing reinforcement.
Types of reinforcement for the foundation
To perform a strong foundation frame, it is recommended to use fiberglass reinforcement. This material has such positive characteristics that make it more acceptable for the construction of the foundation, namely:
– affordable cost;
– long period of operation;
– low temperatures resistance;
– Corrosion resistance;
– increased strength of the material.
Also, steel reinforcement made on a periodic or smooth profile is perfect for the implementation of the reinforced concrete foundation. The question immediately arises: what is a periodic profile? It is a rod with a certain corrugation, which is the protrusion of the metal located at an angle to the axis. The main function of such a rifting is as strong as possible and best combine reinforcement and concrete.
When choosing reinforcement, you need to think about its reliability. This quality can be determined based on the properties of a particular material.
Also important when buying reinforcement is a step of transverse corrugation. The smaller the distance between the steps, the better the adhesion of concrete and reinforcement will be.
The main and fundamental quality of reinforcement is its transverse diameter. For the construction of the foundation during the construction of a small building or house, rods with a diameter of 10-12 mm are suitable. Also, a reinforcing mesh made of flattened steel in the form of a circle is often used for the foundation. It is able to provide structures with an increased level of strength.
The grid frame
To date, thanks to scientific and technical achievements, there is an opportunity to make a mesh frame at home. To do this, you need to have a special gun with which the rods of the reinforcement are connected with annealed wire made of metal 1-3 mm in diameter.
Such devices make it possible not to spend a lot of time to perform this work (to make one section is needed about two seconds of time). It also increases its quality. What kind of deformation or skew of the frame in this case is impossible due to a stable tightening force of wire.
Among the advantages of a special gun required for this work, they distinguish that it is very easy and convenient to manage. Even a novice builder will be able to cope with him. To work with it, you need to perform only two following actions: install the nozzle and press the “Start” button.
In the process of fixing the reinforcement, it is necessary to adhere to some rules that will allow to obtain a reinforcing cage of a high level of reliability.
First of all, it is worth paying attention to the fact that the external boundaries of the frame should play for the formwork slightly. Due to this, the correct thickness is created equal to at least 50 mm.
In addition, a small space should be made between the frame and the bottom of the trench. To do this, often use special plastic nozzles. In the absence of such parts, bricks or wooden beam are placed under the frame, after which they are attached to the ground using wire pins, thanks to this they provide reinforcement stability in one position when pouring the foundation.
There should be no dust, dirt, garbage or rust on the reinforcing cage and formwork. If necessary, all this must be removed. After that, you can fill the foundation. Cleaning surfaces is necessary so that the concrete sucks successfully.
