Stair-beam-free multi-runway concrete cantilever stair
The invention relates to a stair-beam-free multi-runway concrete cantilever stair which comprises stair flight plates, platform plates and main beams. The stair-beam-free multi-runway concrete cantilever stair is characterized in that each stair flight plate comprises a first stair flight and a second stair flight, each platform plate comprises a first platform and a second platform, and each first stair flight, the corresponding first platform, the corresponding second stair flight and the corresponding second platform are connected in sequence to form a multi-runway stair unit; and each second platform is connected to the corresponding main beam, reinforcing steel ribs are embedded in the stair flight plates, the platform plates and the main beams, and the reinforcing steel ribs are connected to form steel rib frameworks. Compared with the prior art, the stair-beam-free multi-runway concrete cantilever stair has the advantages that the shear torsion resistance can be effectively enhanced and the like, and a structural design scheme is provided for the concrete cantilever stair with multiple runways, without stair beams and without the unfavorable conditions of plate constraint at the other sides of support main beams and the like.
本发明涉及一种无梯梁多跑混凝土悬挑楼梯，包括梯段板、平台板和主梁，其特征在于，所述梯段板包括第一梯段和第二梯段，所述平台板包括第一平台和第二平台，所述第一梯段、第一平台、第二梯段和第二平台依次连接，形成一个多跑楼梯单元，所述第二平台连接到主梁上，所述梯段板、平台板和主梁内均预埋有加强钢骨，各加强钢骨相连接形成钢骨骨架。与现有技术相比，本发明具有可有效加强抗剪扭能力等优点，为多跑、无梯梁、支座主梁另一侧无板约束等不利情况下的混凝土悬挑楼梯提供一种结构设计方案。
