Anti-typhoon, anti-seepage and cold-bridge-breaking double-layer waterproof metal roofing system

Abstract

The invention discloses an anti-typhoon, anti-seepage and cold-bridge-breaking double-layer waterproof metal roofing system. The anti-typhoon, anti-seepage and cold-bridge-breaking double-layer waterproof metal roofing system comprises first waterproof roofing plates and second waterproof roofing plates, wherein the first waterproof roofing plates and the second waterproof roofing plates are eachof a U-shaped structure and are arranged up and down. The second waterproof roofing plates are fixedly connected with a structure layer located below the second waterproof roofing plates through second fixed seats. The first waterproof roofing plates are fixedly connected with the second waterproof roofing plates through first fixed seats. A first panel occlusion piece and a second panel occlusionpiece are arranged on each first fixed seat and each second fixed seat correspondingly, wherein small angles are formed between each first panel occlusion piece and the corresponding first fixed seatas well as each second panel occlusion piece and the corresponding second fixed seat, and each first panel occlusion piece and the corresponding first fixed seat as well as each second panel occlusion piece and the corresponding second fixed seat are connected relatively and rotationally. The side edges of the two adjacent second waterproof roofing plates are in fixed occlusion with the upper part of the corresponding second panel occlusion piece and then a second roofing occlusion part is formed. The lower part of each first fixed seat and the corresponding second roofing occlusion part formdetachable fixed connection. The side edges of the two adjacent first waterproof roofing plates are in fixed occlusion with the upper part of the corresponding first panel occlusion piece and then afirst roofing occlusion part is formed. According to the anti-typhoon, anti-seepage and cold-bridge-breaking double-layer waterproof metal roofing system, fatigue damage caused by long-term friction between the roofing plates and the fixed seats is avoided, and wind resistance, the water tightness and the gas tightness are excellent.

Description

technical field [0001] The invention relates to the technical field of building roof systems, in particular to a double-layer waterproof metal roof system with anti-typhoon, anti-leakage and broken cold bridges. Background technique [0002] At present, the main structure of large-scale long-span public buildings is mostly constructed in the form of steel structure. In the maintenance structure system, the roof generally adopts the standing seam metal roof system in the form of complex multi-layer structure. [0003] First of all, in the standing seam roof system, the metal roof panel and the fixed seat are connected by a tight seam. In areas such as coastal typhoon cities with high wind pressure, the panel is prone to deformation, resulting in relative displacement between the panel and the fixed seat. And come off, produce wind lift and water leakage accident. [0004] Secondly, the metal roof panel in the standing seam roof system is a free expansion and contraction syst...

AI Technical Summary

Problems solved by technology

[0013] The purpose of the present invention is to solve the problems of the traditional standing seam metal roof system, such as weak wind resistance, easy leakage, easy to produce expansion and deformation damage, weak secondary waterproof function, easy to produce cold bridges, etc., to provide a typhoon-resistant, anti-seepage Double-layer waterproof metal roof system with leakage and broken cold bridge
