Quick connection structure and method of cast-in-place joint section of cable tower beam prefabrication and assembly construction
The invention discloses a quick connection structure and method of a cast-in-place joint section of cable tower beam prefabrication and assembly construction. The structure comprises a tower column horizontal steel bar (1) of a cable tower column (5). The tower column horizontal steel bar (1) is fixedly connected with a pre-embedded frame stiff skeleton (2). An pre-embedded supporting key box (3)is arranged on the pre-embedded frame stiff skeleton (2), a prefabricated frame stiff skeleton (9) is fixedly connected with a beam horizontal steel bar (8), a prefabricated beam supporting key box (10) is arranged on the prefabricated frame stiff skeleton (9), and a horizontal steel beam (4) is fixed through the pre-embedded supporting key box (3) and the prefabricated beam supporting key box (10). According to the method, steel bar binding and steel bar welding construction of the joint section of the cable tower and the cross beam are omitted, a total construction period is shortened by about 30%-40%, construction cost is reduced by 20%-30%, meanwhile, a part of aloft work is reduced, and an aloft construction operation risk is decreased.
本发明公开了一种索塔横梁预制拼装施工现浇接缝段快速连接构造及方法，其特征在于，包括索塔塔柱（5）的塔柱水平钢筋（1），塔柱水平钢筋（1）与预埋框架劲性骨架（2）固定连接，预埋框架劲性骨架（2）上设有预埋支承键盒（3），预制框架式劲性骨架（9）与横梁水平钢筋（8）固定连接，预制框架式劲性骨架（9）上设有预制横梁支撑键盒（10），通过预埋支承键盒（3）和预制横梁支撑键盒（10）固定水平钢梁（4）。本发明的方法取消了索塔与横梁接缝段钢筋绑扎和钢筋的焊接施工，总工期减少近30%‑40%，降低施工成本20%‑30%，同时减小了一部分高空作业，降低了高空施工作业风险。
