Abstract
Disclosed is a column reinforcing structure using V-shaped tie bars, in which V-shaped tie bars and reinforcing tie bars are used together in a pre-assembled reinforcement when reinforcing an existing column by concrete jacketing such that it is possible to effectively confine the concrete while preventing buckling of main reinforcing bars without installing cross ties and construction can be carried out very quickly and simply.
Claims5
A column reinforcing structure, comprising:
- a column formed of reinforced concrete;
- a pre-assembled reinforcement installed such that the pre-assembled reinforcement surrounds an outer surface of the column;
- and
- concrete covering the pre-assembled reinforcement such that the pre-assembled reinforcement is embedded in the concrete,
- wherein the pre-assembled reinforcement includes:
- a plurality of main reinforcing bars extending in a longitudinal direction and spaced apart from each other;
- a plurality of V-shaped tie bars, each of which is bent in a shape of “V” with a bent part and one pair of legs parts such that an inside of the bent part comes into contact with one of the main reinforcing bars and ends of the leg parts face the outer surface of the column;
- and
- reinforcing tie bars coupled with the plurality of main reinforcing bars in a lateral direction.
