Rebar planting is the operation of drilling holes in concrete and placing rebar inside it. In fact, rebar planting is used as reinforcement and concreting to strengthen concrete, improve dimensions or add a new member to the existing concrete structure. This process is applicable in all concrete sections with different thicknesses
The rebar planting process is applicable in all concrete sections with different thicknesses. For example, if there is a weakness in the bearing capacity of a part of the structure that requires its local strengthening, in most cases, it is not possible to destroy and rebuild, therefore, by planting rebar and adding a new part to it, the bearing capacity can be increased. significantly increased.
What is the use of rebar planting in concrete?
Reinforcement of columns in concrete structures and foundations
Installation of metal plates in order to implement the facade in the structure
Reinforcement of the building by concrete jacketing method
Connecting building facilities equipment to columns and roofs (such as air ducts and electrical ducts)
Installing connecting plates to build a new beam or column
Adding new parts such as roof, shear wall, beam and column to the implementation structures done
Steps to plant rebar in concrete
Drilling holes in concrete with a drill or a corer
Cleaning the concrete hole with an air blower
Cleaning the walls with a brush
Repeating cleaning the walls and blowing air
Injection of adhesive and retainer inside the hole
Installation of rebar in concrete
Be patient for sticking the rebar according to the type of rebar
What are the standards of rebar planting?
Matching the strength of the existing structure with calculations
Required drilling methods
Structure connection direction (top, horizontal and vertical)
Ambient and concrete temperature during planting
Concrete type and conditions (cracked, carbonized)
access and geometrical limitations
determination of rebar location in reinforced concrete
The planting of the rebar in the column
Planting rebar in the column can be done in order to extend the column in the existing structure, connect the concrete beam to the column, plant the rebar in the column to implement the stair railing, connect the new structural element to the column or access other purposes.
Influential factors in the planting of rebars can be mentioned the minimum distance between the rebars and the location of all the rebars inside the chamout and maintaining the concrete cover or concrete cover. Planting rebar in the column is of particular importance due to the limitation of the planting space, because if any execution error occurs, the structural performance of the existing column can be affected.
Rebar implantation in the foundation
Planting rebar in the foundation in order to integrate the existing foundations, increase the height of the foundation in order to carry the load as well as possible, or modify the dimensions of the foundation from one or more aspects, or other cases of this category.
The best drilling method for planting rebar in the foundation is to use the drilling system, the use of drilling system is not recommended due to the cutting of the buried reinforcements in the section, because this process can cause damages in terms of load bearing and safety for the project. brought.
Before any action to plant rebar in the foundation, the size of the desired rebar for planting rebar in the foundation should be determined according to the type of load and taking into account all the restrictions related to rebar planting, then the planting depth The rebar is also calculated and the execution process takes place.
