Cantilever bent cap of prefabricated formwork and temporary stiffening truss and construction method of cantilever bent cap
The invention relates to the technical field of bridge construction, in particular to a cantilever bent cap of a prefabricated formwork and a temporary stiffening truss and a construction method of the cantilever bent cap of the prefabricated formwork and the temporary stiffening truss. A temporary stiffening truss is detachably and fixedly installed on the upper side face of the prefabricated formwork through a plurality of pin shaft inserting grooves, the temporary stiffening truss comprises a plurality of sets of reinforcing units laid on the outer side face of the straight web plate, and the reinforcing units are fixedly installed on the outer side face of the straight web plate through pin shafts used in cooperation with the pin shaft inserting grooves. Connecting joints are arranged in the reinforcing units, every two adjacent reinforcing units on the same layer are fixedly connected through the connecting joints, and every two adjacent reinforcing units on different layers are fixedly connected through bolts. The temporary stiffening truss is temporarily anchored with the outer wall of the prefabricated formwork and is stressed and deformed together with the prefabricated formwork, but the rigidity of the temporary stiffening truss is larger than that of the prefabricated formwork, so that the temporary stiffening truss can bear more force of post-pouring concrete, deformation of the prefabricated formwork is reduced, and engineering quality and safety are guaranteed.
本发明涉及桥梁施工技术领域，具体的是一种预制模壳及临时加劲桁架的悬臂盖梁及其施工方法，本发明包括预制模壳，预制模壳上设置有销轴插槽；预制模壳上侧面通过多个销轴插槽可拆卸式固定安装有临时加劲桁架，临时加劲桁架包括有多组平铺在直腹板外侧面上的加固单元，加固单元通过与销轴插槽配合使用的销轴固定安装在直腹板的外侧面上；加固单元中设置有连接接头，同层相邻的两组加固单元之间通过连接接头进行固定连接，异层相邻的两组加固单元之间通过螺栓固定连接；通过临时加劲桁架通过与预制模壳外壁进行临时锚固，与预制模壳共同受力变形，但因其刚度较预制模壳大，可以承受较多后浇混凝土的力，从而减小预制模壳变形保证工程质量和安全。
