Formwork flexible connecting and anchoring device
The invention relates to the technical field of formwork fixing devices, in particular to a formwork flexible connecting and anchoring device. The device comprises a supporting disc, a stud, a pre-tightening nut, a fixing short sleeve and a puller bolt which are sequentially arranged from left to right; a clamping sleeve is arranged in the fixing short sleeve, the pre-tightening nut is in threaded connection to the stud, and the overall appearance of the clamping sleeve is in a circular truncated cone shape with the small left portion and the large right portion; and the clamping sleeve is formed by splicing at least two petal bodies, and the left end face of the puller bolt abuts against the right end faces of the petal bodies. Through the arrangement of the petal-shaped clamp, when the puller bolt is screwed into the fixing short sleeve, the puller bolt can push the clamp to move towards the main pressing contact surface with the inner diameter gradually reduced, the petal-shaped clamp is extruded by the main pressing contact surface to be gradually shrunk and finally enclasped on a tie bar, then the pre-tightening nut is screwed, so that the pre-tightening nut gradually abuts against the left end face of the fixing short sleeve, according to the characteristic that the action of force is mutual, the supporting disc abuts against the outer wall of the formwork, and therefore tensioning and fixing of an inner formwork and an outer formwork are achieved.
本申请涉及模板固定装置的技术领域，是一种模板灵活连接锚固装置，其包括从左至右依次设置的支撑盘、螺柱、预紧螺母、固定短套、顶紧螺栓，固定短套内设置有夹套，预紧螺母螺纹连接在螺柱上，夹套的整体外形呈左小右大的圆台状，夹套由至少两个的瓣体拼合而成，顶紧螺栓的左端面顶紧在瓣体的右端面上。通过设置瓣状的夹具，当顶紧螺栓向固定短套内旋拧时，顶紧螺栓可以推动夹具向内径逐渐缩小的主压触面移动，瓣状夹具受到主压触面的挤压会逐渐收缩，并最终抱紧在拉筋上，再通过旋拧预紧螺母，使预紧螺母逐渐顶紧在固定短套的左端面上，根据力的作用是相互的这一特点，使支撑盘顶紧在模板的外壁上，从而实现内外模板的拉紧、固定。
