Abstract

The invention discloses a strip-shaped reinforced joint for connection of an H-shaped steel beam and the short edge of a wide steel pipe concrete column. A flange of the H-shaped steel beam is rigidly connected to the side face of the wide steel pipe concrete column through strip-shaped reinforcing plates; a web plate of the H-shaped steel beam is rigidly connected to the side face of the wide steel pipe concrete column through combination of a connecting plate and high-strength bolts; the web plate of the H-shaped steel beam is connected with one end of the connecting plate through the high-strength bolts, and the other end of the connecting plate is welded to the side face where the short edge of the wide steel pipe concrete column is located; the end faces of the flange of the H-shaped steel beam are welded to the strip-shaped reinforcing plates; the strip-shaped reinforcing plates are closely attached and fixed to the side face where the short edge or the long edge of the wide steel pipe concrete column is located; and an inserting plate penetrating through the wide steel pipe concrete column is connected between the two strip-shaped reinforcing plates arranged on the opposite side faces of the wide steel pipe concrete column. The strip-shaped reinforced joint is easy to construct and machine and effective, machining and manufacturing difficulty is reduced, the rigidity and strength of the joint and a joint area are guaranteed, and it is guaranteed that concrete in a pipe has the good pouring quality.

Description

technical field [0001] The invention relates to a belt-shaped reinforced joint used for connecting H-shaped steel beams and short sides of wide steel-filled concrete columns, which can be widely used in the rigid connection between H-shaped steel beams and the short sides of wide steel-filled concrete columns in multi-high-rise steel structures . Background technique [0002] In the multi-story steel structure, the steel beams are mostly H-shaped steel beams, and the steel columns are mostly rectangular wide concrete-filled steel tube columns. The rigid connection of steel beams and steel columns is the most basic measure to provide the overall rigidity and seismic performance of the structure. At present, the commonly used rigid connection is to set a transverse diaphragm at the position corresponding to the beam flange of the steel column, and the internal force of the steel beam flange is transmitted to the steel column through the diaphragm, thus forming a rigid connect...
