Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and in particular relates to a steel hanging column pin shaft connection node structure of a suspension structure. Background Art

[0002] With the development of the construction industry, an unconventional steel structure, the inclined suspended structure, has gradually emerged. This inclined suspended structure has the overall shape of an inverted trapezoid, with a larger top and a smaller bottom. Its structural characteristics include a central core tube and a top-level steel truss. The suspended structure is connected to the top-level steel truss through a hanging structure, and the lower part is connected to each floor through inclined steel suspenders, thus creating a column-free space on the lower floors.

[0003] Conventional suspension structure steel columns are in a vertical state, and the suspension nodes are usually connected by steel sleeve threads. However, the steel columns of inclined suspension structures are inclined from top to bottom toward the main structure, and the installation using steel sleeve threaded connections is difficult and inconvenient to construct. If the traditional steel structure pin connection is used, that is, the pin lug is welded to the cover plate or bottom plate at the end of the steel member, this type of pin lug connection is prone to stress concentration and damage. The safety of the suspension structure is highly dependent on the stability of each node, and the failure of any node may have a serious impact on the safety of the entire structure. Therefore, the development of a new type of suspension connection node that is suitable for inclined suspension structures and can ensure the safety of the node is crucial to ensuring the stability and safety of the entire suspension structure.
