Permanent and temporary combined tensioning prefabricated assembly component connecting and fixing structure and fixing method
The invention relates to a permanent and temporary combined tensioning prefabricated assembly component connecting and fixing structure and fixing method. The method comprises the steps that 1, unit assembly is conducted, wherein an upper split body and a lower split body of a prefabricated component are assembled and then vertically and temporarily tensioned to form a unit; 2, unit connection is conducted, wherein every two units are longitudinally arranged into a group to be connected and longitudinally and temporarily tensioned; 3, tensioning and longitudinal permanent tensioning are conducted, wherein temporary tensioning between every two adjacent units is sequentially dismantled for tensioning, and steel strands penetrate into the units for permanent tensioning; 4, vertical permanent tensioning is conducted, wherein permanent tensioning is conducted on a vertical prestress threaded steel bar of each unit, and mud jacking and anchor sealing are conducted; and 5, the fourth steps are repeated, and vertical and longitudinal connection is completed. According to the permanent and temporary combined tensioning prefabricated assembly component connecting and fixing structure and fixing method, through the permanent and temporary combined tensioning mode, the seam width between every two adjacent components meets the requirement, waterproof rubber strips are fully extruded to achieve a good waterproof effect, every five units of the component are integrated, and the problem of local settlement of the prefabricated component under the poor geological condition is effectively solved.
本发明涉及一种永临结合张拉的预制拼装构件连接固定结构及固定方法，包括：第一步，拼装单元：预制构件的上分体和下分体拼装后竖向临时张拉形成一个单元；第二步，单元连接：以两个单元纵向排列为一组连接并纵向临时张拉；第三步，放张及纵向永久张拉：按顺序先后拆除相邻两个单元之间临时张拉进行放张，并穿入钢绞线永久张拉；第四步，竖向永久张拉：对每个单元竖向预应力螺纹钢棒进行永久张拉，并压浆、封锚。第五步，重复上述四步，完成竖向、纵向连接。本发明通过永临结合张拉方式既保证相邻构件间缝宽满足要求，使防水胶条充分挤压达到较好的防水效果，又保证了构件每五个单元为一个整体，有效解决在不良地质条件下的预制构件局部沉降问题。
