Large-span disassembly-free stepped structure based on steel bar truss floor support plate and construction method of large-span disassembly-free stepped structure
The invention discloses a large-span disassembly-free stepped structure based on a steel bar truss floor support plate and a construction method of the large-span disassembly-free stepped structure, and belongs to the technical field of building construction. The large-span disassembly-free stepped structure comprises a bottom cross beam, a top cross beam, and a plurality of inclined steel beams, ladder plates and steps, which are connected between the bottom cross beam and the top cross beam; and a plurality of steel supporting plates are connected to the tops of the inclined steel beams in a spacing manner in the length direction of the inclined steel beams, the ladder plates are sequentially spliced into a ladder shape through a plurality of integrally-connected ladder plate units, the ends of the ladder plates are erected at the tops of the steel supporting plates, and concrete is poured between the ladder plates and the steps. According to the stepped structure, a supporting system does not need to be erected on site, wood formworks do not need to be erected, jacking treatment is locally conducted according to the span requirement of the steel beams on site, the construction period is shortened, in addition, galvanized steel sheets of steel bar truss floor support plates do not need to be dismantled, and the site construction time is shortened. After structure construction is completed, only part of steel bars need to be bound for fixing, and the construction period is remarkably shortened.
本发明的基于钢筋桁架楼承板的大跨度免拆阶梯结构及其施工方法属于建筑施工技术领域，该大跨度免拆阶梯结构包括底部横梁、顶部横梁、以及连接在底部横梁和顶部横梁之间的多个斜钢梁、梯板和踏步，斜钢梁的顶部沿其长度方向间隔连接有多个钢托板，梯板由若干个一体连接的梯板单元依次拼接成阶梯状，梯板的端部搭设在钢托板的顶部，梯板和踏步之间浇筑混凝土。该阶梯式结构无需在现场搭设支撑体系，不需要支设木模板，只需要根据现场钢梁跨度要求，局部进行回顶处理，缩短工期，另外钢筋桁架楼承板的镀锌钢板无需拆除，减少现场施工时间。结构施工完成后只需要绑扎部分钢筋进行固定，显著缩短工期。
