Easy-to-install shallow-buried concrete-filled steel tubular column foot structure
The invention discloses an easy-to-install shallow-buried concrete-filled steel tubular column foot structure. The easy-to-install shallow-buried concrete-filled steel tubular column foot structure comprises a concrete-filled steel tubular column and H-shaped steel brackets, the H-shaped steel brackets are located on the four sides of the root of the concrete-filled steel tubular column and connected with the concrete-filled steel tubular column in an equal-strength welding mode to form a cross-shaped column foot, H-shaped steel supports are arranged on the lower sides of the ends of the H-shaped steel brackets, the upper ends of the H-shaped steel supports are welded to the H-shaped steel brackets, and the lower ends are in spot welding connection with a bottom fixing steel plate through bolts. According to the structure, the axial force and bending moment transmission capacity of the column foot of the concrete-filled steel tubular column is greatly enhanced, and the requirement for the embedding depth of the column foot is not high. Compared with a normatively suggested method for guaranteeing the axial force and bending moment transmission capacity by increasing the column foot embedding depth, the invention is easy to construct, small in excavation depth and good in economical efficiency, the structural stress requirement can be met, on-site construction and installation can be convenient, the column foot can be directly placed on a foundation cushion layer, the structure can be widely applied to structural engineering in which the axial force and bending moment of the bottom of the concrete-filled steel tubular column need to be reliably transmitted, and the column foot embedding depth is not suitable for being too large.
一种易安装的浅埋式钢管混凝土柱柱脚构造，包括钢管混凝土柱和H型钢牛腿。H型钢牛腿位于钢管混凝土柱根部四侧，与钢管混凝土柱等强焊连接组成十字形柱脚；在H型钢牛腿端部下侧设置H型钢支撑，H型钢支撑上端与H型钢牛腿焊接连接，下端通过螺栓和底部固定钢板点焊连接。该构造极大增强了钢管混凝土柱柱脚传递轴力和弯矩的能力，且对柱脚埋置深度要求不高。相对于规范建议的通过增大柱脚埋置深度来保证其传递轴力、弯矩能力的方法，本发明施工简单、开挖深度小、经济性好，既能满足结构受力要求，又能使现场施工安装方便，可直接搁置于基础垫层之上。可广泛应用于需要可靠传递钢管混凝土柱柱底轴力、弯矩，但柱脚埋置深度不宜过大的结构工程。
