Prefabricated steel structure stair with handrail convenient to replace
The invention discloses a prefabricated steel structure stair with handrails convenient to replace. The prefabricated steel structure stair comprises rear beam columns, a wall face, brackets and the handrails, wherein connecting plates are fixedly welded to the left ends and the right ends of the rear beam columns and the left ends and the right ends of front beam columns, the rear beam columns are arranged behind the front beam columns, a first platform and a second platform are fixedly installed on the front side of the wall face, and the first platform is arranged on the left of the second platform. According to the prefabricated steel structure stair with the handrails convenient to replace, the handrails, studs and rotary connecting pieces are arranged, screws and embedded nuts are matched to pull the two adjacent handrails, the two adjacent handrails are made to be tightly attached to the rotary connecting pieces, meanwhile, sliding blocks slide in sliding grooves, the size compensation effect is achieved, and then the studs at the bottom of the spliced handrails penetrate through a wooden pedal and a supporting plate, fastening nuts are rotated, the effect of fixing the handrails is achieved, splicing and mounting of the handrails can be completed without welding, subsequent dismounting and replacement of a new handrail are facilitated, and using is more practical.
本发明公开了一种便于更换扶手的预制钢结构楼梯，包括后梁柱、墙面、托架和扶手，所述后梁柱左右两端以及前梁柱左右两端均焊接固定有连接板，且后梁柱设置在前梁柱后方，所述墙面前侧固定安装有第一平台与第二平台，且第一平台设置在第二平台左方。该便于更换扶手的预制钢结构楼梯，设置有扶手、螺柱和旋转连接件，螺杆与预埋螺母配合拉动相邻的两个扶手，使相邻的两个扶手贴紧旋转连接件，同时滑块在滑槽内滑动，起到尺寸补偿的作用，随后拼接完成的扶手底部的螺柱贯穿木质踏板以及托板，转动紧固螺母，起到固定扶手的作用，无需使用焊接即可完成扶手的拼接和安装，便于后续拆卸更换新的扶手，使用起来更具有实用性。
