External prestressing lower slideway beam device for translation and construction method
The invention discloses an external prestressing lower slideway beam device for translation and a construction method. The external prestressing lower slideway beam device comprises a reusable prestressing inhaul cable, a prestressing anchorage device, front back counter-force beams and a lower slideway beam. During use, the counter-force beams are arranged on a traditional lower slideway beam atintervals in the length direction, holes are reserved in the counter-force beams, and the prestressing inhaul cable penetrates through the holes reserved in the counter-force beams to be tensioned andanchored. According to the external prestressing lower slideway beam device, the prestressing inhaul cable can be used for bearing horizontal jacking force during jacking translation, the number of longitudinal steel bars in the translation lower slideway beam is reduced, the external prestressing inhaul cable can be disassembled and assembled in a segmented mode to be alternately used forwards,and the prestressing inhaul cable can be recycled after a project is finished; an external prestressing lower slideway beam device is adopted in overall translation of a building, the device is simplein structure, the high strength of the prestressing inhaul cable is fully utilized, the prestressing inhaul cable is alternately reused in a segmented mode and reused after being recycled, the usingamount of steel bars in the lower slideway beam can be reduced, and the construction cost is reduced.
本发明公开了一种平移用体外预应力下滑道梁装置及施工方法，包括可以重复利用的预应力拉索、预应力锚具、前后反力梁、下滑道梁。使用时，在传统下滑道梁长度方向上间隔设置反力梁，反力梁预留洞口，预应力拉索穿过反力梁预留洞口后张拉锚固。本发明可以利用预应力拉索承担顶推平移时的水平顶推力，减少平移下滑道梁内的纵向钢筋数量，体外预应力拉索可以分节段拆卸拼装交替向前倒用，并且项目结束后预应力拉索可以回收重复利用；建筑整体平移中采用体外预应力下滑道梁装置，该装置结构简单，充分利用预应力拉索高强度，分节段交替倒用，回收后重复利用，可以减少下滑道梁中钢筋用量降低工程造价。
