Description

Technical Field

[0001] The utility model relates to the field of roofs, in particular to a roof structure. Background Art

[0002] Nowadays, many industrial buildings and public buildings have higher and higher requirements for large spans and large spaces, so most of the roof structures are designed as steel roof panel structures;

[0003] After searching, it was found that the Chinese patent publication number CN205822544U disclosed "A Factory Roof Structure". The factory roof structure described in the utility model has a roof body that is set to a structure made of multi-layer materials, which can effectively improve the sealing performance of the roof body, and different layer components can also play different roles. The supporting grid effectively ensures the bearing capacity safety of the entire factory roof structure, ensures the overall supporting performance of the roof structure, and avoids the problem of collapse or bending. The setting of the insulation layer isolates the heat exchange between the inside and outside of the factory building, achieving the purpose of thermal insulation. The waterproof layer can ensure that there is no leakage and infiltration of gas and liquid inside and outside the factory building, further improving the sealing performance. The factory roof structure described in the utility model has a simple structure and is easy and quick to manufacture. Through the cooperation of various components, it not only has a strong bearing capacity safety, but also can play an effective isolation and waterproof sealing function for the inside of the factory building. The main purlins and secondary purlins can bear the load on the roof body, preventing the roof body from deforming due to its own weight, causing cracks between the roof bodies of different roof components, and improving the reliability of the roof body in use;

[0004] At present, a waterproof layer and a thermal insulation layer are generally set between the roof layer and the steel structure. The waterproof layer and the thermal insulation layer are used to improve the thermal insulation and waterproof performance of the roof structure. When the roof is impacted (such as hail weather), extreme weather will cause a certain impact on the roof layer, and the roof layer is required to have a certain compressive strength and protective performance. It is more practical to fill a rubber layer between the steel structure and the roof, which can not only play a certain waterproof role, but also has a certain buffering and protective performance, but the rubber layer needs a certain height limit to facilitate the filling of the rubber layer.
