Preset assembly type bracket for bridge 0 # block pouring and construction method
The invention discloses a preset assembly type bracket for bridge 0 # block pouring and a construction method, and is suitable for the technical field of bridge 0 # block construction. Bracket steel boxes are symmetrically embedded in the two side walls of a pier body of a bridge pier in the upward direction of the bridge, opposite-pull-rod hole channels are reserved, triangular brackets arranged on the two side walls of the pier body are oppositely pulled through pull rods penetrating through the opposite-pull-rod hole channels, the upper end and the lower end of each triangular bracket are connected through a hanging base, and each hanging base comprises a hanging base body; a bracket shear key is arranged on the outer side of the hanging seat body, the bracket shear key is inserted into the bracket steel box in a matched mode, a bracket assembly is arranged over the hanging seat body, a through hole corresponding to the opposite-pull-rod hole channel is transversely formed in the bracket assembly, and a pull rod penetrates through the through hole in the bracket assembly and the opposite-pull-rod hole channel to oppositely pull the triangular brackets on the two side walls of the pier body. The bracket structure is of an assembly type structure, damage to a pier body caused by the mode that the bracket is fixed through a welding technology is avoided, and the effects of being convenient to disassemble, low in construction difficulty and high in efficiency are achieved.
本发明公开了桥梁0号块浇筑的预设装配式托架及施工方法，适用于桥梁0号块施工技术领域。本发明托架顺桥向上在桥墩墩身两侧壁对称预埋托架钢盒和预留对拉杆孔道，设置于墩身两侧壁的三角托架通过穿入对拉杆孔道的拉杆对拉，每一所述三角托架上下两端均通过挂座连接，挂座包括挂座本体，挂座本体外侧具有一牛腿剪力键，所述牛腿剪力键匹配插入托架钢盒内，挂座本体正上方设有牛腿组件，牛腿组件上横向开设有与对拉杆孔道对应的通孔，拉杆穿入牛腿组件上的通孔和对拉杆孔道将墩身两侧壁的三角托架对拉。本发明托架结构为装配式结构，避免了采用焊接工艺固定托架的方式造成墩身的损伤，具有拆卸方便施工难度小效率高的作用。
