MEMBER JOINING METHOD AND MEMBER JOINING STRUCTURE FOR PRECAST CONCRETE STRUCTURE
To improve the degree of freedom of construction in a precast concrete structure and to reduce the cost.SOLUTION: A first member (12) having a first reinforcement receiving hole (23) on a side surface is erected at a predetermined position, and a temporary support member (28) is attached to the first member (12) (ST1, ST2). A second member (13) having a second reinforcement receiving hole (22) on an end surface is placed on the temporary support member (28), and the first reinforcement receiving hole (23) and the second reinforcement receiving hole (22) are opposed to each other (ST3). A falling-off prevention reinforcement 24 is arranged so as to extend over the first reinforcement receiving hole (23) and the second reinforcement receiving hole (22) (ST4). A filling material 14 is filled (ST5) in a gap G between the second member (13) and the first member (12), a tension material 15 is arranged (ST6), and after the filling material 14 is cured, prestress is introduced (ST7) into the second member (13) and the first member (12) by applying tensile force to the tendon 15. Thereafter, the temporary support member (28) is removed (ST8).SELECTED DRAWING: Figure 5
【課題】プレキャストコンクリート構造物における施工の自由度を向上し、且つコストを低減する。【解決手段】第１鉄筋受容孔（２３）を側面に有する第１部材（１２）を所定の位置に立設し、第１部材（１２）に仮支持部材（２８）を取り付ける（ＳＴ１、ＳＴ２）。第２鉄筋受容孔（２２）を端面に有する第２部材（１３）を仮支持部材（２８）の上に載置し、第１鉄筋受容孔（２３）と第２鉄筋受容孔（２２）とを対向させる（ＳＴ３）。第１鉄筋受容孔（２３）と第２鉄筋受容孔（２２）とに亘るように脱落防止筋２４を配置する（ＳＴ４）。第２部材（１３）と第１部材（１２）との間の空隙Ｇに充填材１４を充填し（ＳＴ５）、緊張材１５を配置し（ＳＴ６）、充填材１４が硬化した後に、緊張材１５に緊張力を付与することで第２部材（１３）及び第１部材（１２）にプレストレスを導入する（ＳＴ７）。その後、仮支持部材（２８）を撤去する（ＳＴ８）。【選択図】図５
