Full-hanging multi-curve-surface special-shaped twisting steel structure ladder
The invention relates to a full-hanging multi-curve-surface special-shaped twisting steel structure ladder. The full-hanging multi-curve-surface special-shaped twisting steel structure ladder comprises an outer side beam, a middle beam, and an inner side beam, the outer side beam and the inner side beam pass through an arc hanging path from the bottom face of a concrete structure beam to be fixedto a transverse beam of the concrete structure beam, a ladder face is mounted between the outer side beam and the inner side beam, the ladder face is composed of a ladder step steel plate, the ladderface is spliced with the outer side beam and the inner side beam to form an H steel shape through the steel plate curving manner, and the ladder has the advantages that through the outer side beam, the middle beam and the inner side beam, the ladder face is provided with fixed points on the outer side, the inner side and the middle, the whole ladder face and three beams form a whole body, whole stress is achieved, meanwhile, the whole steel-structure ladder is designed to be in the H steel shape, steel does not deform, a profile stress structure is not affected, and whole stress of the full-hanging large-radian ladder is met.
本发明涉及一种全悬空多曲面异型扭弯钢结构楼梯，所述的异形扭弯钢结构楼梯，所述的钢结构楼梯包括外侧梁、中间梁、内侧梁；所述的外侧梁和内侧梁均是从混凝土结构梁的底面经弧形悬空的路径直到固定在混凝土结构梁的横向梁上；所述的外侧梁和内侧梁之间设置有楼梯面；所述的楼梯面由梯步钢板组成的，所述的楼梯面通过钢板弯弧的方式与外侧梁以及内侧梁拼装成H型钢状。其优点表现在：通过设置外侧梁、中间梁以及内侧梁，使得楼梯面在外侧、内侧以及中间均具有固定点，使得整个楼梯面与三根梁形成一块整体，达到整体受力，同时将整个钢结构楼梯设计成H型钢状，钢材不变形，不影响型材受力结构，能满足全悬空大弧度的楼梯的整体受力。
