Large-cantilever prestressed bent cap fabricated bracket and construction method
The invention belongs to the technical field of bridge construction, particularly relates to a large-cantilever prestressed bent cap fabricated bracket and a construction method, and provides the following scheme aiming at solving the problem that a pin rod on an existing prestressed bent cap fabricated bracket needs to bear a great load, so that the pin rod is stressed and deformed to finally influence the construction quality of a bridge. Comprising two symmetrical pier columns, a straining beam is arranged between the two pier columns, two symmetrical trusses are arranged outside the two pier columns, supporting frames are arranged on the trusses, four symmetrical reserved holes are formed in each pier column, and pin rods are arranged in the reserved holes. According to the large-cantilever prestress bent cap fabricated bracket and the construction method, the pin rod bearing the construction load can be effectively supported, so that deformation caused by the fact that the pin rod bears the load exceeding the yield limit of the pin rod in the construction process is reduced, and the situation that the bracket on the pin rod deforms or displaces is avoided; and the construction quality is ensured.
本发明属于桥梁施工技术领域，尤其是一种大悬臂预应力盖梁装配式托架及施工方法，针对现有的预应力盖梁装配式托架上的销棒需要承受极大的荷载，会使销棒受力变形最终影响到桥梁的施工质量，现提出以下方案，包括两个对称的墩柱，两个所述墩柱之间设置有系梁，且两个墩柱的外部设置有两个对称的桁架,桁架上均设置有支撑架，所述墩柱上均开设有四个对称的预留孔,预留孔内均设置有销棒。本发明公开的一种大悬臂预应力盖梁装配式托架及施工方法可以有效的对承受施工荷载的销棒进行支撑，从而减少在施工过程中销棒承受到超过其屈服极限的荷载而发生的形变，从而避免销棒上的托架产生形变或位移的情况，保证了施工的质量。
