Connecting and locking device for building formwork
The invention discloses a connecting and locking device for a building formwork, and belongs to the field of building instruments. According to the technical scheme, the upper end and the lower end ofa threaded roller are connected with first threaded rods through threads, rotating handles are fixedly welded to the ends, away from the threaded roller, of the first threaded rods, a first connecting rod is fixedly welded to one side of the threaded roller, a sleeve is fixedly arranged at the end, away from the threaded roller, of the first connecting rod, a second connecting rod is connected toan inner cavity of the sleeve in a sleeved mode, and a second threaded rod is fixedly welded to the end, away from the sleeve, of the second connecting rod. A pre-tightening spring column is arranged, so that when the space between a first building formwork and a second building formwork is loosened, namely a prestress fixing nut is loosened, a pre-tightening spring column extends by utilizing the elastic force of the pre-tightening spring column, therefore, whether the prestress fixing nut is loosened or not can be directly judged from the appearance, accidents are reduced, and the fasteningdegree between the first building formwork and the second building formwork can be judged more visually by inlaying and installing a graduated scale on the surface of the top of a guide rod.
本发明公开了一种用于建筑模板的连接锁紧装置，属于建筑器械领域。本发明技术方案要点：其螺纹滚筒上下两端均通过螺纹连接有第一螺纹杆，第一螺纹杆远离螺纹滚筒的一端固定焊接有转动把手，螺纹滚筒一侧固定焊接有第一连接杆，第一连接杆远离螺纹滚筒的一端固定设有套筒，套筒内腔套接有第二连接杆，第二连接杆远离套筒的一端固定焊接有第二螺纹杆，通过设置预紧弹簧柱利用预紧弹簧柱的弹力当第一建筑模板与第二建筑模板之间松动即预应力固定螺母松动时，预紧弹簧柱伸长，以此可以直接从外观上判断预应力固定螺母是否松动，减小事故发生，通过在导向杆顶部表面镶嵌安装刻度尺可以更直观的判断第一建筑模板与第二建筑模板之间的紧固程度。
