The steel structure stair prestress zipper mechanism comprises a stainless steel stair body and stand columns fixedly installed on the two sides of the two ends of the stainless steel stair body, open grooves are formed in the outer walls of the outer sides of the inner sides of the stand columns, and hydraulic cylinders are fixedly installed at the bottoms of inner cavities of the open grooves; a hydraulic cylinder is fixedly installed at the top of the stainless steel stair body, an adjusting block is fixedly installed at the output end of the hydraulic cylinder, tension bars are arranged on the two sides of the top of the stainless steel stair body, and the two ends of each tension bar are movably installed on the outer wall of the outer side of the adjusting block. Due to the arrangement, the stress of the tension bar is large, the possibility of breakage is increased, in addition, the breakage of the tension bar reduces the improvement on the prestress of the stainless steel stair body, the use of the stainless steel stair body is influenced, and the service life of the stainless steel stair body is shortened.
本发明公开了一种钢结构楼梯预应力拉锁机构及其使用方法，包括不锈钢楼梯本体和固定安装在不锈钢楼梯本体两端两侧处的立柱，所述立柱内侧的外侧外壁上均开设有开槽，开槽内腔的底部处固定安装有液压缸，液压缸的输出端固定安装有调节块，不锈钢楼梯本体顶部的两侧处均设置有拉力杆，拉力杆的两端均活动安装在调节块的外侧外壁上，本发明通过加强组件的设置可以增强拉力杆的强度，避免通过直接通过拉力杆来实现对预应力的改善，此设置会导致拉力杆的受力较大，增加断裂发生的可能性，此外拉力杆的断裂会降低对不锈钢楼梯本体预应力的改善，会影响不锈钢楼梯本体的使用，降低其的使用寿命。
