Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a PTFE membrane fixing structure for irregular roof support cylinders. 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 three-dimensional grid single-layer reticulated shell steel structures. Traditional three-dimensional grid single-layer reticulated shell steel structures are mostly used for flat roofs, and the support is relatively simple. However, the roof of a large museum project has a complex design and is a curved surface with large vertical fluctuations. The support points at the top may not be on the same horizontal plane, which makes the structure of its support tube more complex. If the traditional PTFE membrane fixing construction method is used during the PTFE membrane fixing construction, the advantages and effects of the membrane material will certainly not be able to be brought out. Therefore, there is an urgent need for a PTFE membrane fixing structure for irregular roof support tubes to ensure that each membrane unit can bring out the advantages and effects of the membrane material in terms of curvature, curves, and curved surfaces.
