<p>PROBLEM TO BE SOLVED: To achieve manpower saving and shortening of a construction period by enabling a beam to be constructed by relatively small-scale timbering, in regard to beam construction using a precast member.SOLUTION: Second and third precast members are joined via a joint part on both sides of a first precast member including a column-beam joint and a beam part equivalent to one span. The first precast member comprises a sheath pipe that penetrates between joint surfaces, and a splice reinforcement that is provided along the sheath pipe. A beam main reinforcement straddling the first and second precast members and a beam main reinforcement straddling the first and third precast members are inserted into the sheath pipe, and a lap joint is formed by the splice reinforcement. A grout material is injected into the sheath pipe.</p> |
