Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a PTFE membrane fixing structure for large-span irregular steel structure roofs. Background Technology
[0002] In recent years, with the development of the construction industry, traditional buildings have been given new requirements. While meeting the functional requirements, they must also reflect distinctive cultural features in their design. As a result, there is an increasing number of buildings with complex shapes and varied forms.
[0003] Roof steel structures generally adopt a three-dimensional grid single-layer reticulated shell steel structure. Traditional three-dimensional grid single-layer reticulated shell steel structures are mostly used for flat roofs with relatively simple support. However, the roof of a large museum project has a complex design with a curved surface that fluctuates significantly vertically. Consequently, the three-dimensional grid single-layer reticulated shell steel structure of the roof fluctuates significantly vertically, and the top support points may not be on the same horizontal plane. If the traditional PTFE membrane fixing construction method is used, the advantages and effects of the membrane material will certainly not be able to be demonstrated. Therefore, there is an urgent need for a PTFE membrane fixing structure for large-span irregular steel structure roofs to ensure that each membrane unit can demonstrate the advantages and effects of the membrane material in terms of curvature, curves, and curved surfaces.
