Problems solved by technology

But now the installation personnel in the industry have uneven skills. When installing the brackets, they are crooked, causing the brackets on the roof panel to not be on the same straight line. In this way, the ribs of the installed panels are not straight, which will cause the panels to be unable to freely expand and contract during thermal expansion and contraction. As for the deformation of the roof panel caused by thermal expansion and contraction cannot be eliminated, it often leads to cracking of the roof, distortion of the bracket due to deformation, and water leakage on the roof.

Embodiment 1

[0046] A lock seam metal roof panel system constructed asfigure 1 Shown, comprise roof panel, modular ruler and the connection bracket 7 that roof panel is fixedly connected on the modular ruler.

[0047] The structure of the roof panel is as figure 2 As shown, it includes a flat bottom plate 12 and a male rib 8 and a female rib 9 arranged at both ends of the flat bottom plate 12 , the male rib 8 and the female rib 9 are connected to the flat bottom plate 12 through a bent plate 11 . The male rib 8 comprises a horizontal lower plate 81, a vertical plate 82 and a male rib hook plate 83 connected in sequence, the horizontal lower plate 81 and the vertical plate 82 are perpendicular to each other, and the horizontal lower plate 81 passes through the curved plate 11 and the flat bottom plate 12. side connection.

[0048] The female rib 9 comprises a horizontal bottom plate 91, a long vertical plate 92 and a female rib hook plate 93 connected in sequence. The horizontal bottom pl...

Embodiment 2

[0057] A lock seam metal roof panel system, its structure is basically the same as that of Example 1, the difference is that in this example, the method of forming and fixing the roof panel is different from that of Example 1, and its process is as follows Figure 5 As shown, the following steps are taken:

[0058] (1) The roof panel is pre-bent when forming, pre-bending 0-70°, wrapping the female rib 9 of the roof panel on the male rib 8 of the adjacent roof panel to form a seam, and then the vertical seam of the seam The straight section is toward the end of the male rib 8. In this embodiment, in order to obtain the best effect, the middle part of the vertical section is pre-bent 30° toward the end of the male rib;

[0059] (2) bending and compressing the front end of the female rib 9 on the outer side of the male rib 8;

[0060] (3) Use the undercutting machine to occlude the male rib 8 and the female rib 9 and press the bending section to form a 360° locking seam to fix t...

Embodiment 3

[0063] A lock seam metal roof panel system, the structure of which is basically the same as that of Embodiment 1, the difference is that the front end of the male rib hook plate 83 used in this embodiment also has a male rib that is bent inward to form a hook-shaped structure. Rib reinforcing edge 84 also has inwardly bending at the front end of female rib hook plate 93 equally, forms the female rib reinforcing edge 94 of crotch structure, as Figure 7 , 8 shown. Through the design of the above-mentioned reinforced edge, the mechanical strength of the roof panel itself can be further improved during use due to the use of the edge-wrapping design, and on the other hand, it can also protect the end of the roof panel from wear and tear. The service life is reduced, and the third can also improve the sealing performance and safety performance. Adding the reinforced small side can not only solve the problem of the edge wave of the board, but also solve the overall strength of the...

Abstract

The invention relates to a lock stitch metal roof board system comprising a roof board, a modulus ruler and a connecting support fixedly connecting the roof board on the modulus ruler; the roof boardcomprises a plane base plate, and a male rib plate and a female rib plate arranged on two ends of the plane base plate; a slide hook is arranged between two metal roof boards; the female rib plate wraps the slide hook and the top of the male rib plate of the adjacent metal roof board, and a 360-degree lock stitch is formed via an undercut machine through one-time bending; the modulus ruler comprises a horizontal bottom and lugs located on two sides of the horizontal bottom; the support bottom is connected in support mount holes of the modulus ruler; the slide hook is clamped on top of the support. The lock stitch metal roof board system is good in wind resistance and waterproof performances, high in mounting precision, and more suitable for existing light steel building roof systems.

Description

technical field [0001] The invention relates to a metal roof panel, in particular to a locking seam metal roof panel system. Background technique [0002] At present, the metal roof panels commonly used in construction are mainly divided into the following three forms in terms of installation methods: nailing type, buckle type and lock seam type. The construction speed of the nailed roof panel is slow, and the temperature and stress are concentrated at the nailed joint, which is prone to edge formation and cause leakage; although the buckled roof is easy to install, sometimes false buckling occurs due to the lack of construction experience of the workers. In addition, the snap-fit ​​roof panel has low wind suction resistance, and its watertight and airtight performance is not ideal. The standing lock seam roof panel improves the problems of the above two roof panels. [0003] Standing lock seam roof means that adjacent panels are locked together along the longitudinal edge...
