Large-span prefabricated box girder anti-cracking device and method
The invention belongs to the technical field of prefabricated box girder construction, and particularly relates to a large-span prefabricated box girder anti-cracking device and method. A containing groove is formed in the inner wall of the connecting base. Hydraulic cylinders are embedded in the inner walls of the two sides of the containing groove. Clamping plates are mounted at the telescopic ends of the hydraulic cylinders; a plurality of limiting holes which are uniformly formed are formed in the surface of the clamping plate; a connecting assembly is jointly installed between the multiple clamping plates. The connecting assembly comprises a plurality of connecting rods; through cooperation between the multiple connecting rods and the connecting base, axial torsion of the prefabricated box girder is limited, and the situation that in the process of transporting the prefabricated box girder through the girder transporting vehicle, one side of the prefabricated box girder is stressed due to bumping and the like, and consequently large-angle axial torsion of the prefabricated box girder occurs is avoided; further, the prefabricated box girder is cracked, so that subsequent construction is influenced.
本发明属于预制箱梁施工技术领域，具体地说是一种大跨度预制箱梁防裂装置及方法，包括多个连接座；所述连接座的内壁开设有容纳槽；所述容纳槽的两侧内壁均镶嵌有液压缸；所述液压缸的伸缩端均安装有夹持板；所述夹持板的表面开设有多个均匀设置的限位孔；多个所述夹持板之间共同安装有连接组件；所述连接组件包括多个连接杆；所述连接杆的一端转动连接有套筒，通过多个连接杆与连接座之间的配合，使得预制箱梁的轴向扭转受到限制，避免运梁车在运输的预制箱梁的过程中，由于颠簸等原因而导致预制箱梁的一侧受力，而导致预制箱梁发生大角度轴向扭转，进而造成预制箱梁产生裂缝，从而影响之后的施工建设。
