Threaded hole arrangement structure, bridge support and broken bolt replacement method
The invention relates to the technical field of constructional engineering, in particular to a threaded hole arrangement structure, a bridge support and a broken bolt replacement method.The threaded hole arrangement structure comprises a base body provided with a mounting hole, a connecting column inserted into the mounting hole and a locking mechanism used for locking the connecting column to the base body, and a stop groove is formed in the bottom of the mounting hole; a guide groove is formed in the side wall of the mounting hole; the first end of the connecting column is provided with a threaded hole, and the outer side of the second end of the connecting column is provided with a stop protrusion. When the connecting column is inserted into the mounting hole, the stopping protrusion can enter the stopping groove along the guide groove, the stopping protrusion entering the stopping groove can be staggered with the first end of the guide groove by rotating the connecting column, axial stopping of the connecting column is achieved, and then the locking mechanism is used for locking the connecting column so that the connecting column can be fixed relative to the base body. And after the bolt is broken, the connecting column can be detached from the base body, so that maintenance personnel can conveniently take out the broken bolt left in the threaded hole.
本发明涉及建筑工程技术领域，特别是涉及一种螺纹孔布置结构、桥梁支座及断裂螺栓更换方法，螺纹孔布置结构包括设有安装孔的基体和插设再安装孔中的连接柱以及用于将连接柱锁定在基体上的锁定机构，安装孔的孔底设有挡止槽，安装孔的侧壁设有导向槽；连接柱的第一端设有螺纹孔，连接柱的第二端外侧设有挡止凸起；将连接柱插入安装孔时挡止凸起可沿导向槽进入挡止槽，转动连接柱，可使进入挡止槽的挡止凸起与导向槽的第一端错位，实现对连接柱的轴向挡止，之后利用锁定机构锁定连接柱可使得连接柱相对于基体固定，螺栓断裂后能够先将连接柱从基体上拆除，便于维护人员取出断裂残留在螺纹孔中的螺栓。
