Hollow steel structure stair construction method
The invention relates to a hollow steel structure stair construction method. The hollow steel structure stair construction method comprises installed steel structure stair section beams, T-shaped prefabricated steel plates, L-shaped steel plates and the like, wherein a steel structure is integrally designed in a construction period of a main body structure, the stair section beams connected to the main body structure are constructed in advance, the elevation of the steel beams is determined according to a design drawing, the T-shaped steel plates of the inclined faces of the steel beams are pre-lofted, machined and manufactured by a prefabricated framework machining factory according to the length of stair sections, after being transported to the site, the stair section beams are firmly welded along the span direction of the stair section, generally, the number of the steel structure stair main steel beams is two, only the T-shaped steel plates need to be welded with two main steel pipes, the space between the welded T-shaped plates is hollow, at the moment, L-shaped steel plates are manufactured and processed in a processing factory according to the size of drawings, and after being transported to the site, the L-shaped steel plates are welded with the T-shaped plates to form a treading surface. According to the hollow steel structure stair construction method, the stair finished by the method is good in integrity, high in rigidity and light in self-weight, welding can be performed according to defense lines during construction, and the probability of quality problems caused by human factors is low.
本发明涉及一种镂空钢结构楼梯施工方法，包括安装完成的钢结构梯段梁、T型预制钢板、L型钢板等；其中在主体结构施工期间对钢结构整体设计，预先施工同主体结构连接的楼梯梯段梁，并按照设计图纸确定钢梁的标高，钢梁斜面的T型钢板为预制构架加工厂按照梯段长度预先放样，加工制作，运至现场后沿着梯段跨度方向同梯段梁进行焊接牢固，一般钢结构楼梯主钢梁为两根，只需将T型钢板同两根主钢管焊接即可，其中焊接完成的T型板与T型板之间为镂空的，此时根据图纸大小尺寸在加工厂制作加工L型钢板，运至现场后同T型板焊接，形成踏面。本发明完成的楼梯整体性好，刚度大，自重轻，施工时按照防线进行焊接即可，人为原因造成的质量问题概率小。
