Abstract
The utility model discloses an anti-progressive-collapse beam-column connecting joint of a steel structure, and belongs to the field of steel structures. The device comprises an H-shaped steel beam and an H-shaped steel column, the H-shaped steel beam is connected to the two sides of the H-shaped steel column, box-shaped plates are arranged on the two sides of the H-shaped steel column respectively, the box-shaped plates are welded to a web of the H-shaped steel beam and the inner side of a flange of the H-shaped steel beam, reinforcing steel bars penetrate through the two sides of the two box-shaped plates and the flange of the H-shaped steel column, and the two ends of the reinforcing steel bars are connected with nuts in a fastened mode through threads. The box-shaped plates are utilized, the steel bars are connected between the H-shaped steel beams and the H-shaped steel columns, and the box-shaped plates and the steel bars can greatly improve the tension bearing capacity of the beam-column joint, so that a catenary mechanism of the structure can be fully exerted, and the progressive collapse resistance of the structure is improved. The device is simple in structure and convenient to construct.
