The first method:
The first method is one of the traditional methods in which the workers were forced to demolish a part of the concrete structure to plant rebars so that part of the previous rebars could be removed and they could install new bolts. Due to the shocks and vibrations that are applied to the concrete while working in this method, the concrete is weakened and there is a possibility of its destruction with small impacts. As a result, the use of this method is less common today.
The second method:
In this method, the concrete structure is drilled in specific places and distances for rebar planting, and the rebars or reinforcements are connected to concrete with the help of glue. These adhesives have high resistance and even weather conditions do not separate them. As a result, they are useful in terms of strengthening and the concrete bed does not weaken. However, different adhesives with different qualities are available in the market; Therefore, choosing the type of glue is very important in connecting concrete and reinforcement as well as possible.
Advantages of strengthening the structure by planting rebar
Rebar planting has worked so well in strengthening structures that other methods of strengthening structures have become less important. Among the advantages of planting rebar in structures, the following can be mentioned:
⚜️ By using the method of planting rebar, the dimensions of the foundation can be changed in internal and external walls.
⚜️ It is possible to convert a single foundation into a strip and a strip into a wide one by planting rebar.
⚜️ By using rebar planting, you can build new walls and enlarge the building without the need to destroy and rebuild the building.
⚜️ The use of planting rebar can be used to make handles and extend cantilever beams. In structures such as large commercial buildings or villas, new concrete columns and beams can be made by planting rebar, which make the building stronger. .
⚜️ To change the use of buildings, for example, from residential to commercial, the best and most economical thing is to use rebar planting; Because with this method, the construction space can be easily enlarged without destruction, and new floors can be built. It is possible to prevent the destruction of the walls by planting rebar.
Rebar planting method
The purpose of planting rebar is to connect old concrete to new and to connect steel structures to concrete structures by planting reinforcement and bolts. As we mentioned before, today this work is done through special adhesives between two elements. These connections must be able to withstand external forces entering the structure in every way; Therefore, it is very important to have a skilled and expert person who has the necessary knowledge and awareness about the design and implementation of the installation of reinforcement and bolts and supervises the performance of this work. On the other hand, choosing the right adhesive to resist external forces is also important and needs attention. Usually, reinforcement should be planted in such a way that the tensile strength of the concrete is greater than the tensile strength of the rebar.

How to plant rebar in the column
It is possible to plant rebar in the columns for various reasons. Some of these reasons are:
⚜️ lengthening a column in the building
⚜️ connecting a concrete beam to the column
⚜️ planting rebar in the column to make a sword staircase< br>⚜️ Connecting new structural parts to the column
The things that can have a great effect on planting rebar in the column include the minimum size of the distance between the rebar, the position of planting the rebar and maintaining the concrete cover. In addition, due to the lack of space in the column, it is more difficult to plant rebar in it than in wide spaces, and the smallest execution error can affect the performance of the entire structure.
Rebar planting steps in concrete
For each rebar planting project in concrete, the following steps should be done in order:
- Creating regular holes with a diameter suitable for the rebar with a rotary device or an electric drill with a certain depth
- Cleaning and removing the material from the hole Working in the holes using special blowing devices
- Injecting enough glue and connecting mortar in each hole
- Installing the reinforcement in the place of the glued holes
- 24-hour maintenance of reinforcement and bolts
