Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structure connection, in particular to a steel structure grid connection structure. Background Art
[0002] Steel structure grid is a structural form widely used in construction and industrial fields. It has high strength, high stability and good spatial layout capabilities. However, the traditional steel structure grid connection structure has some limitations in design. It cannot effectively adapt to the connection of steel pipes of different sizes, nor can it meet different connection requirements.
[0003] First, traditional connection structures can usually only adapt to steel pipes of specific sizes. For steel pipes of different diameters or wall thicknesses, customized design or processing is often required, which not only increases manufacturing costs but also prolongs the construction period. In addition, due to the changes in the sizes of different steel pipes, traditional connection methods may also have problems in connection strength and stability, posing a potential threat to the safety of the overall structure; secondly, traditional connection structures lack flexibility in adjusting the connection angle. In actual applications, the connection angle of the steel structure grid may need to be adjusted according to specific needs to meet the spatial layout and functional requirements of buildings or industrial facilities. However, traditional connection methods often cannot meet this requirement, resulting in design limitations and construction inconveniences.

[0037] Example 2
[0038] like Figure 2 and Figure 4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a limiting groove 11 is provided on the upper part of the base 1, and a slide groove 13 is provided on the lower part of the base 1. The inner cavity of the slide groove 13 is symmetrically slidably connected with a first fixed structure 12. The first fixed structure 12 includes a connecting plate 121. The connecting plate 121 is slidably connected with the inner cavity of the slide groove 13. A guide rod 122 is symmetrically fixedly connected to one side of the connecting plate 121. The outer surface of the guide rod 122 is wound with a spring 123. The two springs 123 are fixedly connected to a block 124 on one side away from the connecting plate 121.
