PROBLEM TO BE SOLVED: To provide a connection structure that reduces possibilities of a fall-out of a second member from a first member, due to destruction of first concrete between an inner peripheral surface of a hollow tubular part and a main reinforcement.SOLUTION: In a connection structure 1, a first member 10 includes a hollow tubular part 11 and first concrete 12 filled inside the hollow tubular part 11, and a second member 20 includes a main reinforcement 21 arranged inside the hollow tubular part 11, with an edge part passing through an opening edge, as well as a tie-hoop 22 arranged to surround the main reinforcement 21, and second concrete cast to cover a part of the main reinforcement 21 and the tie-hoop 22 that is not located inside the hollow tubular part 11. A fall-out prevention reinforcement 50 is provided from an outer peripheral part of the hollow tubular part 11 into the hollow tubular part 11, for preventing fall-out of the second member 20 from the first member 10.SELECTED DRAWING: Figure 2 |
