Rebaring is the method of insertion of the Steel bars when,
there is change in design or there is some extension of the present structure.
When Steel rod as per drawing has not been installed.
Rebaring technique is reinforced concrete construction is a method for proper fabrication and placement of reinforcement bar as per the design and drawing of RCC work.
2) Need of Rebaring
The rebars are mainly provided at the junction where the formwork of structural element is closed as well as at the point where a new structural element needs to be bond with the former one.
Change in the design and sudden extension in structure
Steel bars are not placed according to as per design
Various conditions that rebaring process and equipment are changed.
rebaring technique in reinforced concrete construction.
Rebaring technique on a Pre-casted structure.
3) Process of rebaring in reinforced concrete construction.
The three main operations carried out in rebaring for reinforced concrete construction bars are cutting, bending, tying.
The diameter of reinforcement bars used reinforced concrete works mainly ranges from 6 to 42 mm these reinforcement bars comes from the Steel mills in specified lengths.
So during installation the reinforcement bars must be cut into required size.
The design engineer show the details about the bar bending and related work based on which the workers proceed the work.
4) Equipments used for rebaring techniques.
The equipments that is used for Rebaring operation is developed with the time as the size of Bar is increases. large size of bars are difficult to be handled by hand operation.
The uses of chisel and hammer was an early effect is used for bar bending.
