Corner junction and its bonding method of the rebar or steel reinforced concrete structure and the various columnar structures

摘要

PROBLEM TO BE SOLVED: To provide a corner angle joint structure and a joining method to simplify a work to arrange a reinforcing bar or a steel framed reinforced concrete structure and a columnar structure and provide a sufficient bearing and rigidity. ;SOLUTION: In a corner angle joint between a reinforced bar or a steel framed reinforced concrete structure 1 and a columnar structure, the columnar structure is a concrete-filled steel pipe 2-1, and an outer steel pipe 4 having diameter larger than the diameter of the concrete-filled steel pipe 2-1 and length at least approximately equal to the diameter is arranged at the periphery of a corner angle joint between the concrete-filled steel pipe 2-1 and the columnar structure. A reinforcing bar 5 for joining extending from a main reinforcing bar 3-1 on the first side and a main reinforcing bar 3-2 on the second side of the concrete structure 1 and is arranged to a position equivalent to the length of an outer steel pipe. A gap between the concrete-filled steel pipe 2-1 and the outer steel pipe is filled with concrete to fix the concrete-filled steel pipe 2-1, the outer steel pipe, and the reinforcing bar 5 for joining to form a corner angle joint between a concrete structure 1 and the concrete filled steel pipe 2-1.;COPYRIGHT: (C)1999,JPO
