Description

Technical Field

[0001] The utility model relates to the technical field of large-span steel structure building construction, and particularly relates to an assembled diamond-shaped diagonal web member truss structure. Background Art

[0002] Steel trusses are widely used in various large-span steel structure buildings or structures. There are many factors affecting the height of the truss, such as load, span, service function, etc. Selecting an appropriate truss height can save steel consumption and meet the stiffness requirements. Steel trusses often adopt the construction method of being processed into pieces in the factory and then transported to the site for assembly into a whole. This construction method can ensure the processing quality of components and improve construction efficiency to the greatest extent. However, the transportation conditions limit the fixed height of the truss. Therefore, a truss with diamond-shaped diagonal web members that can divide the truss into two parts in the height direction emerges as the times require. It can not only ensure the processing quality of components and construction efficiency, but also break through the limitation of transportation conditions on the truss height.

Each group of three vertical web members is evenly distributed on the side walls of the upper chord and the chord. High-strength bolt structures are screwed between the corresponding upper and lower vertical web members. Eight diagonal web members are fixedly welded to the side walls of both the upper chord and the lower chord. The eight diagonal web members are inclined and connected end to end. Every four diagonal web members are grouped and distributed between adjacent two vertical web members. A welding block is fixedly welded in the middle of each group of diagonal web members. The welding block is welded between the adjacent two diagonal web members. High-strength bolt structures are screwed between the upper and lower welding blocks. The diagonal web members are arranged in a diamond shape.
