Spoke type cable truss structure annular and radial cable system connecting device and using method thereof
The invention discloses a bidirectional cable clamp for a spoke type cable truss structure. The clamp is used for being connected with annular and radial cables of a full-tension structure system, isintegrally of a rectangular plate structure and comprises a plate body, cable grooves, cover plates, force control bolts and a radial connecting lug plates The cable grooves are formed in the upper plate face and the lower plate face of the plate body, the annular cable is arranged in the cable grooves, and the cable groove and the annular cable have the same extension direction; the cover platescovers the cable grooves; the force control bolts are vertically arranged at the two sides of the cable grooves, penetrate through the cover plates and then are fixedly connected with plate bodies atthe two sides of the cable grooves, and the friction force between the cover plates and the annular cable is controlled through rotation; and the radial connecting lug plate is vertically arranged onthe outer side face, close to the radial cable, of the plate body and connected with an anchorage device pin shaft at the end of the radial cable through a pin hole. The bidirectional cable clamp is simple in structure and convenient to construct, the torque of the force control bolts is determined through an anti-sliding test of the cable clamp and the cables, sliding is prevented through friction resistance between the cables and the cable clamp, certain pretension is applied to the annular cable, effective connection of the bidirectional cables and effective transmission of the pretension are ensured, and sliding of a connecting point is prevented.
一种用于轮辐式索桁架结构的双向索夹，用于连接全张力结构体系的环径向索，整体为矩形板块结构，包括板块本体、索槽、盖板、控力螺栓和径向连接耳板；索槽设于板块本体的上下板面上，环向索设于索槽内，两者延伸方向相同；盖板盖设于索槽之上；控力螺栓竖向设于索槽两侧，贯穿盖板后与索槽两侧的板体固连，通过旋转控制盖板与环向索的摩擦力大小；径向连接耳板竖向设于板块本体靠近径向索的外侧面，其与通过销孔与径向索端部的锚具销轴连接。本发明结构简单，施工方便，通过索夹与索的抗滑移试验，来确定控力螺栓的扭矩，索与索夹之间通过摩擦阻力防止滑移，对环向索施加一定的预张力，确保双向索有效连接、预张力的有效传递、防止连接点的滑移。
