CONSTRUCTION METHOD OF PRECAST MEMBER

PROBLEM TO BE SOLVED: To provide a construction method of a precast member capable of improving a degree of freedom of a joining method between a second precast member and a column member, while reducing labor of drawing work of a mechanical joint, in the present invention.SOLUTION: The construction method of the precast member comprises a first process of inserting and connecting a beam main reinforcement 24 projecting from an upper column member 12A into and to a fixed mechanical joint 36 embedded in one end part 30A of an upper beam member 30, by moving the upper beam member 30 in the lateral direction to the upper column member 12A, a second process of placing an upper column member 12B on a lower column member 14B by lowering from above on the other end part 30B side of the upper beam member 30 and a third process of connecting a beam main reinforcement 34 embedded in the upper beam member 30 and the beam main reinforcement 24 embedded in a column-beam connection part 16 of the upper column member 2B by a weld joint. 【課題】本発明は、機械式継手の引き出し作業の手間を低減しつつ、第２プレキャスト部材と柱部材との接合方法の自由度を向上することができるプレキャスト部材の施工方法を得ることを目的とする。【解決手段】プレキャスト部材の施工方法は、上柱部材１２Ａに対して上梁部材３０を横方向へ移動させ、上柱部材１２Ａから突出する梁主筋２４を上梁部材３０の一端部３０Ａに埋設された固定機械式継手３６に挿入して接続する第１工程と、上梁部材３０の他端部３０Ｂ側に、上柱部材１２Ｂを上方から降ろし、下柱部材１４Ｂの上に載置する第２工程と、上梁部材３０に埋設された梁主筋３４と上柱部材１２Ｂの柱梁仕口部１６に埋設された梁主筋２４とを溶接継手によって接続する第３工程と、を有している。【選択図】図４
