Thin-wall square steel tube concrete column stiffened by crosspiece
The thin-wall square steel tube concrete column comprises a thin-wall square steel tube, a plurality of crosspieces and filled concrete, the crosspieces are square rings, are tightly attached to the inner wall of the thin-wall square steel tube and are evenly arranged in the length direction of the thin-wall square steel tube at intervals, and the crosspieces are filled with the filled concrete. And the outer side length of the cross section of the crosspiece is parallel to the inner side length of the cross section of the thin-wall square steel tube. And the thin-wall square steel tube is filled with concrete. The thin-wall square steel tube and the crosspiece are connected through mucilage glue or self-tapping screws, the problems of stress concentration, overlarge residual stress and the like at a welding seam caused by stiffening of a traditional steel member are effectively solved through the mucilage glue, damage to the steel tube is reduced, and the advantages of being convenient to disassemble, reliable in connection and the like are achieved through the self-tapping screws. And meanwhile, transverse deformation of the thin-wall square steel tube is effectively limited by adding the transverse wood, so that the plasticity of steel can be fully developed, the ductility of the structure is effectively improved, and the anti-seismic property of the thin-wall square steel tube concrete column is favorably improved.
本发明的目的是提供一种以横木加劲的薄壁方钢管混凝土柱，包括薄壁方钢管、若干个横木和内填混凝土，横木为方形环，紧贴薄壁方钢管内壁，在薄壁方钢管长度方向上均匀间隔布置，且横木横截面的外边长与其紧贴的薄壁方钢管横截面的内边长平行。薄壁方钢管内部填充混凝土。薄壁方钢管和横木之间采用粘胶或自攻螺钉连接，粘胶的使用有效避免了传统钢构件加劲带来的焊缝处应力集中、残余应力过大等问题，使钢管受损减小，自攻螺钉的使用具有拆卸方便、连接可靠等优点，同时横木的加入有效限制了薄壁方钢管的横向变形，使钢材的塑性能够充分发展，有效提高了结构的延性，有利于提升薄壁方钢管混凝土柱的抗震性能。
