PURPOSE: To facilitate execution and, at the same time, to anchor main reinforcing bars of beams surely and firmly by placing the main reinforcing bars of beams at right angles of an RC structure in the shape of a lattice in a jointing section of a column and beam, and welding and anchoring both main reinforcing bars of beams to each other.
CONSTITUTION: Main reinforcing bars 4, 4, 5 and 5 of beams 2 and 2 at right angles of an RC structure are placed in the shape of a lattice in a joint section of a column and beam, and the both main reinforcing bars 4 and 5 of beams are welded and anchored to each other. According to the constitution, execution can be carried out without using any anchoring metal fixture such as an anchoring plate, etc., and, at the same time, filling efficiency of concrete can be so maintained that it is not lowered.
