Description

Technical Field

[0001] The utility model relates to the technical field of metal roofing systems, in particular to a position limiting and anti-loosening structure of a standing edge locking metal roofing system. Background Art

[0002] With the widespread construction of large-span projects, the use of aluminum alloy metal roofing systems has become more and more widespread. The vertical lock seam metal roofing system is connected by fixing the support and the roof panel. The fixed support of the traditional vertical lock seam roofing system adopts round head, square head, semicircular head, plum head and triangular head, among which the most commonly used end head form in China is plum head. When the roof panel connected by this support is subject to a large wind suction force, the metal roof panel deforms and bends upward, causing the edge to deform. Since the roof panel and the support have less bite surface, the friction area between the fixed support and the roof panel is small, which makes the roof system prone to wind damage.

[0003] The utility model with publication number CN 205777141 U discloses an I-shaped metal roof standing seam fixing support, comprising a base plate, a web plate and an upper end head, wherein the base plate, the web plate and the upper end head are of equal length and the corresponding ends are aligned, and the cross section of the upper end head adopts an inverted I-shaped structure.

[0004] As shown in the above-mentioned utility model, the existing metal roof upright lock edge adopts an inverted I-shaped upper end with a wide upper flange and a narrow lower flange to form a double-layer bite structure with the roof panel to increase the bite area between the roof panel and the fixed support, increase the constraint points when the roof is disengaged and damaged, and increase the mechanical bite force between the roof panel and the support, thereby achieving a certain anti-loosening effect. However, this method is generally suitable for metal roof structures with I-shaped edges, and cannot be fixedly installed for metal roofs of other shapes, and its scope of application is relatively small.
