Construction method of high-pier Y-shaped bent cap and bracket for construction of high-pier Y-shaped bent cap
The invention provides a construction method of a high-pier Y-shaped cover beam and a bracket for construction of the high-pier Y-shaped cover beam, the bracket for construction of the high-pier Y-shaped cover beam comprises a bracket, a lower truss, an upper truss and an opposite-pulling device, the bracket is installed on a pier column through a pier body embedded part, the lower truss is erected on the bracket, the upper truss is arranged on the lower truss, and the opposite-pulling device is arranged on the bracket. Unloading blocks and distribution beams are arranged between the lower truss and the upper trusses, the two sets of upper trusses are arranged on the two sides, in the bridge direction, of a pier stud cover beam, and the opposite-pulling device is connected with the two sets of upper trusses so as to limit the upper trusses. According to the construction method, flexible division can be conducted in combination with the design condition of the capping beam, the load generated in capping beam construction is transmitted to the pier column through the upper truss, the distribution beam, the unloading block and the lower truss and then transmitted to the pier column through the bracket, the poured pier column can be fully utilized for bearing, the occupied area is small, high-altitude operation is little, and construction safety is high.
本申请提供一种高墩“Y”型盖梁的施工方法及其施工用托架，其中，所述高墩“Y”型盖梁施工用托架包括牛腿、下桁架、上桁架及对拉装置，所述牛腿通过墩身预埋件安装在墩柱上，所述下桁架架设在所述牛腿上，所述上桁架设于所述下桁架上，且所述下桁架与所述上桁架之间设有卸荷块及分配梁，所述上桁架位于墩柱盖梁沿顺桥向的两侧设置两组，所述对拉装置连接两组所述上桁架以对上桁架进行限位。本申请能够结合盖梁设计情况灵活的划分，将盖梁施工中产生的荷载通过上桁架、分配梁、卸荷块、下桁架，再由牛腿传递给墩柱，能够充分利用已浇筑的墩柱来进行承载，并且占地面积小，高空作业少，施工安全性高。
