Problems solved by technology

[0003] However, with the method of cast steel joints, due to the long processing period of cast steel joints and the low strength of cast steel parts, the phenomenon of low strength at the connection between high-strength steel components and steel castings is prone to occur
The method of increasing the wall thickness of the main component is mainly applicable to the situation where the size of the main component is much larger than that of other joints, so the scope of application is narrow

Abstract

The invention discloses a connection joint structure of a multi-coupled steel component. The connection joint structure of the multi-limb steel component comprises a main component and a plurality ofconnecting components, the main component is of a hollow tubular structure, the main component is provided with a connection joint area, and the wall thickness of the connecting joint area is greaterthan the wall thickness of the main component; the main component is internally provided with a plurality of first inner strengthening ring plates, and all the first inner strengthening ring plates are arranged in the height direction of the main component at intervals in an arrayed mode; and the multiple connecting components are fixedly connected with the main component, and the ends, fixedly connected with the main component, of the multiple connecting components are located in the connecting joint area. The connection joint structure of the multi-coupled steel component can effectively optimize local force of the main component, an existing method by adopting cast steel joints or increasing the wall thickness of the main component is replaced, the wall thickness of the main component is effectively controlled, the machining period is shortened, and the weight of the multi-coupled steel component is reduced. Therefore, the whole structure cost of the connection joint structure of the multiple-limb steel component is lower than that of the method by adopting cast steel joint design and increasing the wall thickness of the main component.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a connection node structure of multi-joint steel components. Background technique [0002] At present, in the intersection node design of steel structural members, when multi-joint members intersect, the joint design mostly adopts cast steel joints or increases the wall thickness of the main member to the maximum, and then connects other joint members with The main member is intersecting. [0003] However, with the method of cast steel joints, due to the long processing period of cast steel joints and the low strength of cast steel parts, it is prone to the phenomenon of low strength at the connection between high-strength steel components and steel castings. The method of increasing the wall thickness of the main component is mainly applicable to the situation that the size of the main component is much larger than that of other joints, so the scope of application i...
