Connecting structure of special-shaped concrete filled steel tubular column and H-shaped steel beam

ZHENG HUAHAI / LI YUANQI / XIE CHAO

The special-shaped concrete filled steel tubular column and H-shaped steel beam connecting structure comprises an upper column and a lower column of the special-shaped concrete filled steel tubular column, a steel structure node area and an H-shaped steel beam, the steel structure node area is a steel structure component which is formed by a plurality of H-shaped through steel beams and is the same as the special-shaped concrete filled steel tubular column in cross section shape; an upper column and a lower column of the special-shaped concrete filled steel tubular column are welded to an upper flange and a lower flange of the H-shaped through steel beam of the steel structure node area respectively, and the upper flange and the lower flange of the H-shaped steel beam are welded to the upper flange and the lower flange of the H-shaped through steel beam of the steel structure node area respectively. Webs of the H-shaped steel beams and webs of the H-shaped through steel beams of the steel structure node area are connected through connecting plates and bolts. The method has the advantages of less on-site welding work, no influence on concrete pouring in the steel pipe, high construction speed, no projection of the node out of the cylindrical surface, reliable node connection and the like.

异形钢管混凝土柱与H形钢梁连接结构，其包括：异形钢管混凝土柱的上柱及下柱、钢结构节点域及H形钢梁；所述钢结构节点域由若干H形贯通钢梁构成与异形钢管混凝土柱的横截面形状相同的钢结构构件；所述异形钢管混凝土柱的上柱和下柱分别焊接于所述钢结构节点域的H形贯通钢梁的上翼缘和下翼缘，所述H形钢梁的上下翼缘分别与钢结构节点域的H形贯通钢梁的上翼缘、下翼缘焊接，H形钢梁的腹板和钢结构节点域的H形贯通钢梁的腹板通过连接板及螺栓连接。本发明具有现场焊接工作少，不影响钢管内混凝土浇筑，施工速度快、节点不突出柱面，节点连接可靠等优点。
