Inner lining steel pipe stiffened thin-wall square steel pipe concrete column
The invention discloses an inner lining steel pipe stiffened thin-wall square steel pipe concrete column. The concrete column comprises a thin-wall square steel pipe, an inner lining steel pipe and filling concrete. Open plug weld holes are formed in the thin-wall square steel pipe, the inner lining steel pipe is arranged in the thin-wall square steel pipe, and the thin-wall square steel pipe is connected with the inner lining steel pipe through a plug weld; and the thin-wall square steel pipe is filled with the filling concrete. According to the concrete column, the thin-wall square steel pipe is connected with the inner lining steel pipe through the plug weld, so that the welding workload is remarkably reduced, damage to the steel pipes is reduced, the problems of centralized weld concentration, large residual stress and the like are well avoided, adverse effects caused by welding are reduced to a great extent, and the stress performance of the inner lining steel pipe stiffened thin-wall square steel pipe concrete column is improved.
本发明公开了一种以内衬钢管加劲的薄壁方钢管混凝土柱，包括薄壁方钢管、内衬钢管和内填混凝土，所述的薄壁方钢管管壁开塞焊孔，所述的内衬钢管设置在薄壁方钢管的内部，所述的薄壁方钢管与内衬钢管通过塞焊缝连接；所述的薄壁方钢管内部填充混凝土。本发明的薄壁方钢管和内衬钢管之间采用塞焊缝连接，显著减小了焊接工作量，减小了钢管损伤，较好的避免了焊缝集中、残余应力较大等问题，很大程度上减少焊接带来的不利影响，有利于改善以内衬钢管加劲的薄壁方钢管混凝土柱的受力性能。
