Prestressed steel inhaul cable tensioning and tightening device and construction method
The invention provides a prestressed steel inhaul cable tensioning and tightening device and a construction method, and relates to the technical field of steel structure building construction. The prestressed steel inhaul cable tensioning and tightening device comprises a fixed support, two high-strength ropes and a hoisting device; the fixed support is fixed into the middle of an adjusting screwrod; the two high-strength ropes are respectively wound at two ends of the adjusting screw rod; and one end of each high-strength rope is fixed to the fixed support, and the other end of each high-strength rope is connected with the hoisting device. According to the prestressed steel inhaul cable tensioning and tightening device, the two wound high-strength ropes are pulled through the hoisting device, the high-strength ropes generate torque to the adjusting screw rod, so that the adjusting screw rod rotates, inhaul cables at the two ends move towards the middle, and the effect of tightening the steel inhaul cables is achieved. Therefore, prestress tensioning and tightening of the steel inhaul cables can be easily achieved, the device can be suitable for inhaul cables with large diametersand large pre-tightening cable force, the tightening force is easy to control, traditional chain wrench tightening construction can be replaced, thus the situation that a wrench is bent and a chain iscollapsed and cannot be used is avoided, and high safety is achieved.
本发明提供了一种预应力钢拉索张拉拧紧装置及施工方法，涉及钢结构建筑施工技术领域，包括固定支架、高强绳和起重装置；固定支架固定于调节螺杆的中部；高强绳设有两根，分别缠绕于调节螺杆的两端；其中每根高强绳的一端固定于固定支架上，另一端与起重装置连接。本发明通过起重装置，拉动两根缠绕高强绳，高强绳对调节螺杆产生扭矩，使调节螺杆转动，使两端的拉索均向中间移动，起到拧紧钢拉索的作用。因此可以轻松地实现钢拉索预应力张拉拧紧，可适用于大直径索预紧索力较大的拉索，本发明装置拧紧力易控制，可取代传统的链条扳手拧紧施工，从而避免扳手被扳弯及链条崩坏无法使用情况，具有较高的安全性。
