Reinforcement is called Steel fixer in English and is one of the vital steps in the implementation process of various metal and concrete structures. In this technique, the used rebars and steel sections are placed in places that have been determined in advance and on the map. After completing this step, the concrete pouring operation is performed on it, thus making the building as resistant as possible. Reinforcement of steel includes various steps, in each step of which types of rebars must be used in appropriate sizes.
In fact, the reinforcement of the building is carried out to prevent the collapse of the concrete used in the structure and to withstand tensile forces in it. This operation is carried out in order to fully observe and implement the principles of engineering in the construction process. It should be noted that this step should be done before the concrete pouring operation in the building.

? What is reinforcement
Reinforcement includes specific steps that are performed on the rebars used in structures. In fact, the process of cutting, bending and fastening the rebars with reinforcing wire and also placing them in concrete is called steel reinforcement. It should be noted that the rebars are connected to each other by means of welded and metal joints. In carrying out this operation, the specifications of the types of rebar and their thickness are largely taken into account. Rebars, or cut and bent rebars, play an effective role in shaping the concrete skeleton, absorbing energy, ductility, increasing tensile strength, flexibility and preventing cracking of walls.
Types of reinforcement
There are different types of reinforcement, including:
Roof reinforcement
One of the important applications of gridded rebars, or roof reinforcement, is their use in the roof. When using these rebars in the roof, it is necessary to cut and bend various types of yoke and longitudinal beam rebars. Then they are installed in the desired location. Then they are removed from the longitudinal beam reinforcements and placed at the specified distances. In the next step, in order to prevent the beams from twisting and to properly distribute the pressure on the beams in the roof, they are formed around the beams and installed the beams. Finally, in the last step, the supports and rebars are installed. It should be noted that in implementing this technique in the roof, negative moment rebar and EDKA rebar are used.
Column reinforcement
In column reinforcement, where gridded rebars are used in columns, longitudinal reinforcements are cut. Then, among the overlap, forging or coupling methods, one is selected as the most appropriate method to connect the rebars to the column root in the foundation. To determine the length of the column reinforcements, the numbers in the drawing related to the slab thickness, the length of the reinforcement, and the height of the column of the entire skeleton must be added together. After completing this step, the rebars are cut and bent and placed in the desired location from the top.
Floor reinforcement
Floor reinforcement is one of the most important stages of building construction because it plays an important role in the strength and safety of the building. In fact, the purpose of implementing flooring with concrete and gridded rebar is to prevent additional costs to compensate for damage to the building and also to save time.
Reinforcement of the scaffolding
First of all, it should be said that the reinforcement of the slats means the connecting beam between the individual foundations, which creates a kind of foundation similar to a strip foundation. The purpose of using gridded rebar in the slats is to transfer and distribute the pressure applied to the individual foundation to the other foundations. The slats can be used like a connecting beam and prevent it from contacting the soil.
Steps to implement reinforcement
Reinforcement is used in all parts of the building. However, its application in each part is different. The size of the bars, the shape of the arrangement, the thickness and the way they are connected to the foundation are among the differences in the use of this type of technique. The steps for implementing this technique include the following.
Buying and selecting rebar
This work should be done by experts and executive engineers. Because, as mentioned, every part of the building requires some kind of rebar. In general, galvanized rebar should be used for all parts to prevent rust.
Rebar transfer
Since the rebars are very long, they must be transported by truck. This is necessary to prevent damage to the rebars. It should be noted that iron straps are used to transport the rebars and keep them stable along the way. Also, a crane must be used to unload the rebars.
Cutting and bending rebars
Rebars must be cut and bent based on their application and location. Bending rebars is very sensitive because the slightest mistake in the cutting process can cause cracking and breaking of the concrete. Rebars are bent by hand or by power tools.
Installing reinforcement and choosing the method for doing it
Several methods are used to install reinforcement, and the methods used vary depending on the type and location of the reinforcement.
Conclusion
In the above text, we examined reinforcement from zero to one hundred. The use of this practical technique in construction has become essential, and along with the Mannesmann pipe, colored iron sheets and steel slabs are used in the construction of concrete and metal structures.
