Description

Technical Field

[0001] The utility model relates to the technical field related to steel structures, and in particular to a high-strength prefabricated steel structure beam-column connection node. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and regularly maintained. Steel structures need to use connection devices when connecting. Therefore, a high-strength prefabricated steel structure beam-column connection node is particularly needed.

[0003] However, the existing high-strength prefabricated steel structure beam-column connection nodes are prone to generate large residual stresses during on-site welding, which affects the force-bearing performance of the nodes. The construction procedures are complicated, and the construction speed and quality are often difficult to guarantee.
