Lightweight assembly type beam-type scissors stair
The invention belongs to the field of fabricated buildings, and particularly relates to a lightweight fabricated beam type scissor stair. The beam type scissor stair comprises a stair step plate and two longitudinal beams, the two longitudinal beams are integrally connected to the left side and the right side of the bottom face of the stair step plate, reserved anchoring steel bars are arranged at the upper beam ends of the two longitudinal beams, and reserved holes are formed in the first step of the stair step plate. Hanging nails are arranged in overlapped areas of the stair step plates and the longitudinal beams; according to the light-weight assembly type beam-type scissor stair, a plate-type scissor stair is optimized into the beam-type scissor stair, the weight of the assembly type scissor stair is optimized while the strength requirement of the assembly type stair is met, the stair weight is reduced to 3.1 tons from 5.1 tons, the potential safety hazard of hoisting is reduced, and the hoisting efficiency is improved. And the hoisting requirement can be met only by configuring the 6015 tower crane, so that the leasing cost of the tower crane is greatly saved.
本发明属于装配式建筑领域，具体涉及一种轻量化装配式梁式剪刀楼梯；梁式剪刀楼梯包括楼梯踏步板和两道纵梁，两道纵梁一体连接于楼梯踏步板的底面左右两侧，两道纵梁的上部梁端设置预留锚固钢筋，楼梯踏步板的第一级台阶设置预留孔；楼梯踏步板和纵梁叠合区域设置吊钉；本发明提供的一种轻量化装配式梁式剪刀楼梯，将板式剪刀楼梯优化为梁式剪刀楼梯，在满足装配式楼梯强度要求的同时优化了装配式剪刀楼梯的重量，楼梯重量由5.1吨减为3.1吨，不仅降低了吊装的安全隐患，而且只需配置6015塔吊即可满足吊装需求，大大的节省了塔吊租赁成本。
