The invention discloses a steel structure elevator derrick and a design method thereof, and belongs to the technical field of elevator derricks. The steel frame columns are attached to the side wall of the foundation pit, the bottoms of the steel frame columns are connected with the concrete foundation through column foot fixing pieces, and the sides of the steel frame columns are connected with the side wall of the foundation pit through side embedded pieces. The steel frame beams are arranged between the adjacent steel frame columns, are connected with the main body structure beams through cross beam connecting pieces, and comprise side surface beams, back surface beams, reinforcing beams and lifting hook beams; and the gate posts are arranged between the two back beams of each floor. Only the steel frame columns can be seen from the outside of the elevator, the derrick contour line is simple, and the appearance is attractive; when sightseeing is conducted from inside to outside, visual segmentation is avoided, and the sightseeing effect is enhanced; the steel frame column is attached to the side wall of the foundation pit, and the stability of the steel frame column is improved; the problem that the stability of the frame column cannot be met during calculation according to a normative method is solved by adopting an envelope design method for inversely calculating the length coefficient of the column through buckling analysis and assuming that part of the column is unstable and damaged.
本发明公开了一种钢结构电梯井架及其设计方法,属于电梯井架技术领域,包括钢框柱、钢框梁和门柱;钢框柱与基坑侧壁贴合设置,底部通过柱脚固定件与混凝土基础连接,侧部通过侧埋件和与基坑侧壁连接;钢框梁设置在相邻的钢框柱之间,并通过横梁连接件与主体结构梁连接,钢框梁包括侧面梁、背面梁、加固梁和吊钩梁;门柱设置在每个楼层的两根背面梁之间。本发明从电梯外部只能看到钢框柱,井架轮廓线简洁,外形美观;在电梯内向外部观赏时,避免视觉分割,增强观光效果;钢框柱与基坑侧壁贴合设置,提高钢框柱的稳定性;采用屈曲分析反算柱计算长度系数和假设部分柱子已失稳破坏的包络设计方法,解决按规范法计算时框架柱稳定性无法满足的问题。
