[0002] With the intensification of the energy crisis and the improvement of environmental awareness, building energy conservation has received more and more attention. Traditional roof structures have certain limitations in terms of insulation and waterproofing, and cannot meet the needs of modern buildings for energy conservation and environmental protection. In addition, for example, in a high temperature environment, the temperature of the metal roof can reach more than 70°C. How to ensure the overall stability of the metal roof under uneven temperature is a long-term problem that needs to be solved. Therefore, the development of a new type of energy-saving roof structure has important practical significance. For the general tourist center roof, it is a non-walkable slope roof, the construction conditions are relatively dangerous, and it needs to be formed in one time and cannot be reworked. The roof has a large number of curved surfaces, and the roof formed by conventional roof tiles is uneven as a whole and has an unsightly appearance. Summary of the invention

Otherwise, the hot melt adhesive pad is in the form of a hard gasket. Considering the impact of temperature on the metal fish scale plate roof, the metal heat conduction will be uneven when heated, which will affect the deformation of the metal roof, especially at the installation position. The use of hot melt adhesive pads can solve the above problem.
