Curved vertical seam metal roof panel system

Abstract

The invention relates to a curved vertical seam metal roof panel system used for long-span light roof covers, such as, civil engineering, stations, airports, and the like, and especially relates to a wind-resisting metal roof panel and a supporting base. The curved vertical seam metal roof panel system is characterized in that a curved vertical seam supporting base 1-1 is meshed with a left curved vertical seam roof panel rib 2-1 and a right curved vertical seam roof panel rib 2-2, so that the curved vertical seam metal roof panel system is formed; or a folded curved vertical seam supporting base 1-2 is meshed with a left folded curved vertical seam roof panel rib 3-1 and a right folded curved vertical seam roof panel rib 3-2, so that a folded curved vertical seam metal roof panel system is formed. The curved vertical seam metal roof panel system has the advantages that the meshing capacity among the metal roof panels is enhanced, the constraint force of the supporting base for the roof panel is increased and the capacity of the metal roof panel for resisting wind is increased.

Problems solved by technology

[0002] In recent years, with the widespread use of metal roof panels in my country, more and more building roof panels use standing seam metal roof panels. However, this kind of standing seam metal roof panels have insufficient wind resistance. The metal roof was torn, resulting in a large area of ​​rain leakage, which may endanger the safety and normal use of the building and its internal personnel and facilities

[0003] Utility model patents "Safe structure of standing seam metal roof against wind (authorization announcement number CN 203613740U)", "uniform pressure and wind resistance accessories for standing seam metal roof panels (authorization announcement number CN 203429908U)", "wind resistance of metal roof panels Clamp (Authorized Announcement No. CN 103291008A)" and "A Wind-resistant Fixture for Angle Type III Metal Roof Panels (Authorized Announcement No. CN 103883079A)", the above patents use different types of clip locks to fix the upright seams, and the clip locks pass through Bolt fastening, although it can play a certain role in wind resistance, but the bolt joints are prone to water leakage, corrosion, loosening and destroying the overall aesthetics of the roof panel

This kind of roof panels connected by vertical seams has strong pressure-bearing and rainproof ability, but because the ribs of two adjacent roof panels are not integrally engaged with each other, especially there is no connection structure at the vertical seams, the roof panels are When encountering strong winds, the roof panels are separated and disengaged due to negative pressure suction on the top surface of the roof panels, causing tearing of the metal roof panels, which affects its ability to resist wind exposure

[0006] Based on the above patents, theoretical novelty checks and practical engineering applications, the current technology for metal roof panels that require wind resistance is single, and the wind resistance performance is poor. In heavy wind and rain, it is easy to cause roof panels to tear and leak.
