Description

Technical Field

[0001] The utility model relates to the technical field of high-rise steel structure buildings, in particular to a circular tube column node structure. 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 frames and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect the components or parts. 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 maintained regularly. Structural nodes are one of the main elements of the building structure system. Generally speaking, the components are limited to the maximum size of production or transportation, so the components that connect two or more fixed bodies are called structural nodes. At the same time, because of the large selection of node types, special node structures are sometimes deliberately designed to increase structural toughness or reduce structural internal forces.

[0003] The publication number CN218622930U discloses a circular tube column corbel node structure, including a circular tube column, several groups of corbels, at least one group of through holes opened on the circular tube column, the corbels are inserted into the through holes to penetrate the circular tube column, and the corbels are connected and fixed to the circular tube column, which fully solves the stress problem of the circular tube column and meets the requirement of not pouring concrete on the outside of the circular tube column, which is more suitable for the needs of buildings with larger spaces. This steel structure node is assembled by plug-in connection, and the web directly penetrates the circular tube column. Although the structure is simple and the stability of the corbel is enhanced, for the steel frame transfer layer structure of the high-rise steel structure, this node structure is too simple to play a role in strengthening the strength of the node structure, reducing the stability of the high-rise steel structure.
