冷弯薄壁型多箱体踏步钢结构圆弧悬旋楼梯设计与制造

Design and Manufacture of Cold-formed Thin-walled Multi-box Stepped Steel Curved Arc

选用冷弯薄壁型多箱体踏步钢结构设计制造的圆弧悬空旋转楼梯,理论上可建造任意大型、任意旋转曲度、任意跨度、任意载重的高精准度实用楼梯(这种无中间支撑的任意旋转楼梯以下表述为"圆弧悬旋楼梯")。圆弧悬旋楼梯有四大要素,强度、刚度、精准度和美观度,其设计原则和计算方法与之前钢结构楼梯设计理论有很大不同。新技术趋于完善实用,使"圆弧悬旋楼梯"在设计制造安装全程中实现了数字化、系统化和规范化。

The use of cold-formed thin-walled multi-box stepper steel structure design and manufacture of circular floating rotary staircase,theoretically,you can build any large,arbitrary rotation,any span,any load of high precision practical staircase(This non-intermediate support of any rotating staircase described below as 'arc hanging staircase'). Arc hanging staircase has four elements,strength,stiffness,accuracy and aesthetics,its design principles and calculation methods with the previous steel staircase design theory is very different. This new technology tends to improve and practical,so that 'arc hanging staircase' in the design and manufacture of the whole process to achieve a digital,systematic and standardized.
