High-altitude cable bent tower cross beam construction bracket pre-pressing assembly
The invention discloses a high-altitude cable bent tower beam construction bracket pre-pressing assembly which comprises a plurality of upper carrying pole beams arranged in parallel and a plurality of beam supports arranged on the upper portions of the upper carrying pole beams, the ends, close to a tower column, of the upper carrying pole beams are fixed to the tower column, and a plurality of installation point positions are evenly arranged on the upper carrying pole beams. A steel strand is arranged on each mounting point position in a matched mode, and the steel strands are fixed to the mounting point positions of the upper carrying pole beam through upper anchoring assemblies and fixed to the lower cross beam through lower cross beam anchoring assemblies; the pre-stressed steel strand is used for tensioning the support, the jack is used for applying pre-pressing load to the steel strand, non-elastic deformation of the support is eliminated, huge balance weight is replaced, operation and construction in a high-altitude narrow site are facilitated, and more accurate loading can be achieved according to the actual bearing state of the cross beam structure. The problems that an existing conventional support pre-pressing method is difficult to hoist, high in safety risk, high in labor consumption, long in time consumption and uncontrollable in load are solved.
本发明公开了一种高空索塔横梁施工托架预压组件，包括若干根平行设置的上扁担梁、若干个设置于上扁担梁上部的横梁支架，上扁担梁靠近塔柱的一端与塔柱固定，上扁担梁上均匀布置有多个安装点位，每一安装点位上配合设置一钢绞线，钢绞线采用上锚固组件固定于上扁担梁的安装点位处，采用下横梁锚固组件固定于下横梁；采用预应力钢绞线对支架进行张拉，采用千斤顶对钢绞线施加预压荷载，消除支架非弹性变形，代替了巨大的配重且便于高空狭窄场地的操作施工，可根据横梁结构实际承载状态更精准加载，解决目前常规支架预压方法的吊装困难、安全风险高、费工多耗时长、荷载不可控的难题。
