[0002] With the improvement of my country's industrialization level, the functions and forms of buildings are becoming more and more diversified. Steel structure buildings are widely used in various industrial plants, warehouses, large shopping malls and other fields due to their low cost and short construction period. The roof of steel structure buildings usually adopts metal roof system, which is usually composed of metal roof panels, fixed supports and substructures. Usually the substructure refers to purlins. When in use, the metal roof panels are connected to the substructure through fixed supports.

[0003] However, the fixed supports of the existing metal roofing systems are all metal fixed supports, which are in direct contact with the metal roof panels and substructures during use, which are prone to chemical reactions, resulting in obvious hot and cold bridge effects between the metal roof panels and the substructures, which is not conducive to energy saving of buildings; in addition, the metal roof panels will expand and contract under the influence of thermal expansion and contraction and slide relative to the fixed supports. Since both are made of metal materials, they are prone to generate large friction resistance and noise when sliding relative to each other, which not only causes noise pollution to the environment, but also the in-plane force between the fixed supports and the metal roof panels is more obvious, especially when the length of the metal roof panels is greater than 40m, the in-plane force between the fixed supports and the metal roof panels is more obvious.
