Steel-concrete composite structure sliding support damping stair and construction method thereof
The invention relates to a steel-concrete composite structure sliding support damping stair and a construction method thereof, and belongs to the field of stairs. The stair comprises steel stair columns, steel stair beams, stair rest platform plates and stair step plates, and the stair rest platform plates and the stair step plates are cast-in-place reinforced concrete structure plates. Cast-in-place reinforced concrete structures and stair facing bricks are bonded through mortar, construction is convenient, the effect is attractive, and the common quality problems such as hollowing are not likely to happen. The tops of the stair step plates and the stair rest platform plates at the upper ends are integrally formed through pouring, and the bottoms of the stair step plates are slidably connected with the stair rest platform plates at the lower ends through polytetrafluoroethylene sliding plates. According to the steel-concrete composite structure sliding support damping stair, the steelbeams and the steel columns which are reliably connected a main body steel structure are adopted to form an independent stair steel frame, the influence of earthquake force on the stair is reduced, the high energy dissipation and shock absorption effects are achieved, and a shock isolation layer is formed between an upper stair section and an lower stair section. The stair rest platform plates are in sliding connection with the stair step plates, so that the resonance effect of walking and running of people is reduced.
本发明的钢‑混凝土组合结构滑动支座减震楼梯及其施工方法属于楼梯领域，该楼梯包括钢梯柱、钢梯梁、楼梯休息平台板和楼梯踏步板，楼梯休息平台板和楼梯踏步板为现浇钢筋混凝土结构板。现浇钢筋混凝土结构与楼梯饰面砖采用砂浆粘结，施工便捷，效果美观，不易产生空鼓类质量通病。楼梯踏步板的顶部与其上端的楼梯休息平台板一体浇筑成型，底部与其下端的楼梯休息平台板之间通过聚四氟乙烯滑动板滑动连接。发明采用与主体钢结构可靠连接的钢梁、钢柱形成独立的楼梯间钢框架，降低地震力对楼梯的影响，具有较高的消能减震作用，还在上下梯段间形成隔震层。楼梯休息平台板与楼梯踏步之间为滑动连接，降低人群行走、跑动的共振效应。
