technical field

The invention relates to the field of steel structures, in particular to a shock-absorbing steel structure node member.

Background technique

Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect components or parts. Because of its light weight and simple construction, it is widely used in large workshops, venues, super high-rises and other fields.

When the existing steel structure is connected, the shock absorption effect of the node position is poor, so that when the shear force is large, it is easy to cause the bolt at the node to break, which affects the stability of the steel structure.
