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

Embodiment 2

[0085] Please also refer to Figure 6 and Figure 7 , is a schematic diagram of the node structure of the multi-joint steel member provided by Embodiment 2 of the present invention. The difference between the joint structure 200 of the multi-joint steel member provided by the second embodiment of the present invention and the joint structure 100 of the multi-joint steel member provided by the first embodiment of the present invention is that:

[0086] In this embodiment, the main component 10 is provided with a node area steel pipe 201 corresponding to the connection node area 11, and the node area steel tube 201 is connected to the inner wall of the main component 10, and the wall thickness of the node area steel tube 201 is greater than that of the main component 10. wall thickness. Specifically, since the connection node region 11 is an important stress-bearing region, the wall thickness of the steel pipe 201 in the node region should be greater than that of the main memb...

Embodiment 3

[0092] Please also refer to Figure 8 to Figure 11 , is a schematic diagram of the node structure 200 of the multi-joint steel member provided by Embodiment 3 of the present invention. The difference between the joint structure 300 of the multi-joint steel member provided by the third embodiment of the present invention and the joint structure 100 of the multi-joint steel member of the first embodiment of the present invention is that:

[0093] The main component 10 includes a first part 301 and a second part 302, the first part 301 is a straight pipe arranged vertically, the second part 302 is an oblique pipe arranged obliquely relative to the vertical center of the first part 301, the second part 302 is connected with the top end of the first part 301 to form a first inclined angle C. That is to say, the main component 10 is a partially inclined pipe, and in order to ensure the stress and facilitate the force analysis, the first angle C of inclination should not be too larg...

Abstract

The invention discloses a joint structure of a multi-coupled steel component. The joint structure of the multi-coupled steel component comprises a main component and a plurality of connecting components, the main component is of a hollow tubular structure, the main component is provided with a connection joint area, a plurality of first inner strengthening ring plates are arranged in the position,corresponding to the connection joint area, in the main component, 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 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 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 node structure of multi-joint steel components. Background technique [0002] At present, in the design of intersecting joints 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, and then connects other joints with the main member. Components intersect. [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 is narrow.
