Pre-stressed tendon auxiliary positioning structure and threading sleeve head matched with pre-stressed tendon auxiliary positioning structure
The invention provides a pre-stressed tendon auxiliary positioning structure and a threading sleeve head matched with the pre-stressed tendon auxiliary positioning structure, the pre-stressed tendon auxiliary positioning structure comprises a guide cylinder and a clamping mechanism, the clamping mechanism is used for being erected on a reinforcing bar, the outer wall of the guide cylinder is provided with a plurality of first sinking grooves, and the groove bottoms of the first sinking grooves are communicated with the interior of the guide cylinder through first round holes; a sleeve assembly is installed outside the guide cylinder, a plurality of second sinking grooves are correspondingly formed in the inner wall of the sleeve assembly, balls are clamped between the corresponding first sinking grooves and second sinking grooves in a rolling mode, and the balls stretch into the guide cylinder through the first round holes; the threading sleeve head is used for fixing the prestressed tendons inserted into the sleeve through a plurality of pointed screws; the auxiliary positioning structure can be erected on a steel bar structure to provide positioning and auxiliary moving effects for subsequent laying of prestressed tendons, and the threading sleeve heads can be mounted at the ends of the prestressed tendons to prevent loosening of steel wire ropes at the ends of the prestressed tendons from affecting threading and dragging, so that the prestressed tendons can penetrate through the auxiliary positioning structure, and operation and construction are facilitated.
本发明提供了一种预应力筋辅助定位结构及配套使用的穿引套头，辅助定位结构包括导向筒及卡紧机构，卡紧机构用于搭架在钢筋条上，导向筒的外壁设有多个第一沉槽，第一沉槽的槽底通过第一圆孔与导向筒内部连通；导向筒的外部安装有套筒组件，套筒组件的内壁对应设有多个第二沉槽，对应的第一沉槽与第二沉槽之间滚动卡放有滚珠，滚珠经第一圆孔伸入导向筒的内部；而穿引套头通过多个尖头螺钉对插放在套管内的预应力筋进行固定；辅助定位结构可搭架在钢筋结构上，为后续预应力筋的铺设提供定位及辅助移动的效果，穿引套头可安装在预应力筋的端部，防止预应力筋端部钢丝绳的松散影响穿设拖拉，以便穿过辅助定位结构，便于作业施工。
