Description

Technical Field

[0001] The utility model relates to the technical field of space trusses, in particular to a tie rod structure of a space truss. Background Art

[0002] At present, the steel truss structure is developing rapidly. Many airports, stations, gymnasiums and other buildings widely adopt this type of structure. This type of structure usually has a large span and can meet the requirements of the building function for space. The tie rod, as an important component of the spatial steel structure truss, mainly plays the role of connecting the main rod and the role of the structural secondary beam. The conventional tie rod is mainly a single rod structure. It is used in places with high structural strength requirements, such as places with large spans and large spacings;

[0003] In the Chinese patent with publication number CN220225928U, a tie rod structure for space trusses is mentioned. The tie rod structure does not increase the additional installation volume. When the span or spacing increases, there is no need to increase the number of tie rods, which greatly saves the installation cost, improves the economic benefits of the enterprise, and solves the problem of easy loosening and snow accumulation of the steel structure truss covering; however, the tie rod structure is connected to the truss main rod through the fixed plates at both ends, but the installation between the fixed plates and the truss main rod is not firm enough, which affects the connection effect between the tie rod structure and the space truss and reduces the practicality. Therefore, we introduce a tie rod structure for space trusses. Utility Model Content
