Shaped temporary steel stair
The invention belongs to the field of construction temporary facilities of construction sites, and particularly relates to a shaped temporary steel stair. The shaped temporary steel stair comprises stair sections, railings, railing inserting grooves, connecting pieces, first magnets, second magnets, third magnets, cavities, hydraulic cylinders and valves. The railing inserting grooves are fixed tothe stair sections, the railings are directly connected with the railing inserting grooves in an inserted mode, the railings are in lap joint with an outer frame through hook rings, and the connecting pieces are used for building the railings. Clamping grooves are formed in the two ends of each stair section and used for buckling connection between the stair sections and the outer frame. The railings are built temporarily, the cavities communicate with the hydraulic cylinders, the third magnets are fixedly connected to piston rods of the hydraulic cylinders, the second magnets are located onthe upper portions of the third magnets, the first magnets are horizontally and slidably connected with the side walls of the railing inserting grooves, the second magnets and the third magnets are vertically and slidably connected with the side walls of the railing inserting grooves, the second magnets attract the first magnets to loosen the railings, and the third magnets repel the first magnetsto lock the railings. The steel stair is convenient to go up and down, and convenient and easy to build and can further be recycled.
本发明属于建筑工地的施工临时设施领域，具体涉及一种定型化临时钢楼梯。包括楼梯梯段、栏杆、栏杆插槽、连接件、第一磁体、第二磁体、第三磁体、空腔、液压缸与阀门。栏杆插槽固定在楼梯梯段上，栏杆与栏杆插槽直接插入式连接，栏杆与外架勾环搭接，连接件用于搭建栏杆。楼梯梯段两端设有卡槽，用于楼梯梯段和外架进行卡扣连接。栏杆临时搭建。空腔与液压缸连通，第三磁体固定连接在液压缸活塞杆上，第二磁体位于第三磁体上方，第一磁体与栏杆插槽侧壁水平滑动连接，第二磁体与第三磁体与栏杆插槽侧壁竖直滑动连接，第二磁体吸引第一磁体松开栏杆，第三磁体排斥第一磁体锁紧栏杆。本方案钢楼梯上下方便，搭建方便容易，还可以循环利用。
