Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel structure building, specifically relates to a node connecting structure for steel structure building assembly. BACKGROUND

[0002] In the steel structure technology, the connection at the beam-column joint is required to be high, and needs to meet the design specification and requirement. The connection at the beam-column joint directly determines the connection quality of the whole connection frame. In the prior art, the beam-column joint connecting structure is usually designed to be connected by bolts penetrating the steel beam and the column to ensure the connection strength.

[0003] In the prior art, the Chinese utility model patent document with the authorization announcement number CN222632512U discloses a steel structure anti-continuous collapse beam-column joint, which comprises an H-shaped steel beam and an H-shaped steel column. The H-shaped steel beam is connected on both sides of the H-shaped steel column. Box-shaped plates are arranged on both sides of the H-shaped steel column. The box-shaped plates are welded to the web of the H-shaped steel beam and the inner side of the flange of the H-shaped steel beam. Steel bars are arranged through both sides of the two box-shaped plates and the flange of the H-shaped steel column. The ends of the steel bars are connected with nuts through threads. A plurality of first stiffening ribs are arranged at the right-angle connection position of the H-shaped steel beam and the H-shaped steel column.
