METHOD FOR CONSTRUCTING RIGID-FRAMED STRUCTURE
PROBLEM TO BE SOLVED: To join a joint part and a column together without making a reinforcing bar penetrate the joint part from above the joint part.SOLUTION: A method for constructing a rigid-framed structure of an overpass comprises: a process of setting columns 20A, 20B upright at intervals in an overpass width direction; a connection process of lifting PC members 31A, 32, 31B above the columns 20A, 20B such that they are arrayed in the overpass width direction, connecting the PC members 31A, 32, 31B so as to form a connection body which has joint parts 40 corresponding to the columns 20A, 20B and a cross-beam 30 connecting those joint parts 40, and then arranging the joint parts 40, 40 of the connection body above the columns 20A, 20B and the cross-beam 30 of the connection body above the columns 20A, 20B and between the columns 20A, 20B; and a lowering process of lowering the connection body thereafter to insert main reinforcing bars 31c, projecting from one of lower end parts of the joint parts 40, 40 and upper end parts of the columns 20A, 20B into sleeve joints 23 provided to the other.SELECTED DRAWING: Figure 7
【課題】鉄筋を仕口部の上から仕口部に貫通させることなく、仕口部と柱とを接合できるようにする。【解決手段】高架橋のラーメン構造を構築する方法は、柱２０Ａ，２０Ｂを橋幅方向に間隔を置いて立設する工程と、ＰＣ部材３１Ａ，３２，３１Ｂを橋幅方向に配列するよう柱２０Ａ，２０Ｂの上方に揚重し、ＰＣ部材３１Ａ，３２，３１Ｂを接続することによって、柱２０Ａ，２０Ｂに対応する仕口部４０とそれら仕口部４０を接続する横梁３０とを有する接続体を形成し、接続体の仕口部４０，４０を柱２０Ａ，２０Ｂの上方に配置し、接続体の横梁３０を柱２０Ａ，２０Ｂの上方の柱２０Ａ，２０Ｂ間に配置する接続工程と、その後に、接続体を下降させて、仕口部４０，４０の下端部と柱２０Ａ，２０Ｂの上端部のうち一方から突出した主筋３１ｃを他方に設けられたスリーブ継手２３に挿入する下降工程と、を備える。【選択図】図７
