Overhanging type prefabricated steel stair suitable for thick wall
The invention discloses an overhanging type prefabricated steel stair suitable for a thick wall. The overhanging type prefabricated steel stair comprises a pre-buried steel section, a post-installed overhanging beam, a post-installed longitudinal edge beam, a post-installed longitudinal secondary beam and a post-installed stair track plate. The pre-embedded steel section is used for connecting the post-mounted cantilever beam and a bearing wall, and a splicing seam is arranged between the pre-embedded steel section and the bearing wall; according to the embedded steel sections, connection of the afterloading stairway plate and the load-bearing wall is achieved through the anchoring welding nails and the anchoring steel bars, and the stress reliability of the connecting part is guaranteed. The rear-mounted cantilever beam transmits the load to the load bearing wall, and the steel structure cantilever beam is light in structure and good in visual effect. The rear-mounted cantilever beam is large in stress and remarkable in free end deflection, after the rear-mounted longitudinal boundary beam is arranged, the rear-mounted cantilever beam can be cooperatively stressed, structural integrity is improved, the free end deflection of the rear-mounted cantilever beam is reduced, and the structure is smoother. The rear-mounted longitudinal secondary beams can increase the structural integrity, reduce the transverse span of the rear-mounted stairway plate, increase the rigidity of the rear-mounted stairway plate and improve the walking comfort of pedestrians.
本发明公开了一种适用于厚墙的悬挑式预制钢楼梯，包括预埋钢节段、后装悬挑梁、后装纵向边梁、后装纵向次梁和后装楼梯道板；所述预埋钢节段用于连接所述后装悬挑梁和承重墙，所述预埋钢节段与所述承重墙之间设置有拼接缝；本发明预埋钢节段通过锚固焊钉和锚固钢筋实现后装楼梯道板和承重墙的连接，保证连接部位受力的可靠性。后装悬挑梁将荷载传递至承重墙，钢结构悬挑梁结构轻盈，视觉效果较好。后装悬挑梁受力较大且自由端挠度显著，设置后装纵向边梁后，可协同受力，增加结构整体性，减小后装悬挑梁自由端挠度，使结构更加平顺。后装纵向次梁可增加结构整体性，减小后装楼梯道板横向跨径，增大后装楼梯道板刚度，提高行人行走舒适性。
