[0002] As a green building system, steel structure buildings have the characteristics of high rigidity, high strength, light weight and high degree of industrialization. However, the disadvantage of easy rust in a humid environment is a fatal disadvantage that affects the mechanical properties of steel structures, among which the waterproof performance of the roof is the key to the durability of steel structure buildings.
[0003] As the steel structure building system is becoming more and more perfect, the waterproofing of the overlapped joints of the fusion roof panels often has the following problems: the roof panels are fully covered with waterproof membranes. If the 360° vertical seam locking technology is still used, the curvature performance of the material and the airtightness of the locking edge are required to be high; if the roof panels are only covered with waterproof membranes at the troughs, the overall waterproof level of the roof will be reduced. In order to adapt to the overlap of fusion board roof panels, improve the waterproofing and sealing performance of the roof system, and increase the service life of metal roof panels, these have become urgent problems to be solved for fusion roof panels.

[0008] As a further improvement of the above scheme, a glue layer is provided on the inner side of the top of the TPO wave peak cover sheet, and the glue layer is bonded to the locking edge of the roof panel by chemical bonding. The inner sides at both ends of the TPO wave peak cover sheet are respectively welded and fixed to the waterproof base pad at the trough of the roof panel by physical heating. The TPO wave peak cover sheet selects different bonding methods according to the physical properties of the material of the contact parts, which is beneficial to improve the sealing of the overlap of the roof panel and also improves the reliability of the connection between the components.
