Compared with the prior art, the present invention has good wind resistance and waterproof performance and is more suitable for the current light steel building roof system.

Description

Technical Field

[0001] The invention relates to a building roof, in particular to a standing seam metal roof panel. Background Art

[0002] At present, the metal roof panels commonly used in buildings are mainly divided into the following three types based on the installation method: nailing, snap-on and lock-seam. The construction speed of nailing roof panels is slow, and the temperature stress is concentrated at the nailing point, which is easy to produce edges and lead to leakage; although the snap-on roof is easy to install, sometimes false snap-on occurs due to the lack of construction experience of workers. In addition, the snap-on roof panel has low wind suction resistance, and its watertight and airtight performance is not ideal. The vertical lock-seam roof panel improves the problems of the above two roof panels.

[0003] Standing seam roof means that adjacent panels are locked together along the longitudinal edges of the panels during installation, forming a lock seam perpendicular to the roof. The panels are connected by the lock seam to form a tightly connected and almost rigid roof system. The sliding hook hidden in the middle of the lock seam can make the roof panel expand and contract with temperature changes, and connect the roof panel to the secondary structure system, reducing the use of through-plate screws. The standing seam series of panels have their unique advantages, that is, they are fastened together by male and female buckles, and then bitten into shape by a biting machine to meet the requirements of wind resistance.

[0004] However, since the conventional 360° lock-seam roof system panels are connected by brackets and roof purlins, they lack wind resistance and are easily damaged by typhoons in some typhoon areas, causing significant economic losses and even casualties. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a vertical locking seam metal roof panel with strong wind resistance and good waterproof performance.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A vertical lock seam metal roof panel comprises a plane bottom plate and male ribs and female ribs arranged at both ends of the plane bottom plate, a sliding hook is arranged between the two metal roof panels, the female ribs cover the sliding hooks and the top of the male ribs of the adjacent metal roof panels and are bent once by a biting machine to form a 360° lock seam, the straight edge of the 360° lock seam is bent twice by 50 to 70° toward the male rib side, and as a preferred embodiment, the straight edge of the 360° lock seam is bent twice by 60° toward the male rib side. Through the above-mentioned secondary bending, the bite tightness of the plate type can be greatly increased, and the difficulty of the plate type being disengaged when exposed to wind is also increased, thereby greatly increasing the wind resistance performance.

[0008] The described male rib plate includes a horizontally lower plate, a vertical plate, and a male rib hook plate that are integrally formed and connected in sequence. The horizontally lower plate is connected to one end of the planar bottom plate through a bent plate.

[0009] The described female rib plate includes a horizontally bottom plate, a long vertical plate, and a female rib hook plate that are integrally formed and connected in sequence. The horizontally bottom plate is connected to the other end of the planar bottom plate through a bent plate. The long vertical plate is attached to the vertical plate of the adjacent male rib plate, and the female rib hook plate is attached to and wraps the male rib hook plate of the adjacent male rib plate.

[0010] The described female rib hook plate is bent by a hemming machine to be pressed against the long vertical plate for a 360° lock seam, and the attached long vertical plate and vertical plate are bent secondarily towards the male rib plate side.

[0011] Both the male rib plate and the female rib plate adopt straight edges, which increases the angle of the female buckle shape. When strong winds come, it will not be blown up, causing property losses or even casualties.

[0012] An adhesive layer is provided on the inner side of the described female rib plate. For example, an adhesive layer can be used and can be provided at the connection between the long vertical plate and the female rib hook plate. This increases the tightness between the female rib plate, the sliding hook piece, and the male rib plate, thereby increasing the wind resistance and waterproofness.

[0013] The end of the described male rib hook plate is also provided with a reinforcing edge that bends inward.

[0014] The end of the described female rib hook plate is also provided with a reinforcing edge that bends inward.

[0015] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0016] (1) The 360° lock seam is bent secondarily. Especially, by bending the straight edge part of the 360° lock seam 50 - 70° towards the male rib plate side, the tightness between the metal roof panels is increased, thereby increasing the wind resistance. This is because, if the bending degree is greater than 70°, the hemming machine cannot perform hemming. If large-angle (greater than 70°) hemming is to be achieved, the upper plate type size must be increased, but this increases the material consumption and cost, which is not conducive to the market promotion of the product. Thus, below 70° is both a limit angle that can meet hemming and does not require additional materials, that is, on the basis of fixed materials, the wind resistance of the plate type is optimal. When the angle is too small (less than 50°), when bearing wind load, the two plates are likely to separate from the plate seam. If they are bitten at a certain angle, the difficulty of separation is increased, that is, the wind resistance of the plate is increased.

[0017] (2) The inner side of the female rib plate is coated with an adhesive layer, making the connection of the metal roof panels have good waterproofness. At the same time, due to the secondary bending, the tightness between the metal roof panels is further improved, increasing the waterproof performance.

[0018] (3) The male and female ribs of the plate type adopt the method of adding reinforcing small edges at the edge part. Adding the reinforcing small edges can not only solve the problem of the wave at the edge of the plate, but also solve the overall strength after the plate type is engaged, and enhance the wind resistance of the plate.

An adhesive 4 is coated on the inner side of the connection between the long vertical plate 22 and the female rib hook plate 23.

[0038] The bent plate 5 is a "V" plate, one side of which is connected to the flat bottom plate 6, and the other side is connected to the male rib plate 1 or the female rib plate 2; the bent plate 5 connected to the flat bottom plate 6 is 20mm wide and 18mm high; the bent plate 5 connected to the male rib plate 1 or the female rib plate 2 is 17mm wide and 28mm high. The width of the flat bottom plate 6 is 486mm.

[0039] When the present invention is connected and installed, its process steps are as follows Figure 7 As shown, the first step is to stack the male rib plate, the sliding hook plate of one metal roof panel, and the female rib plate of another metal roof panel in sequence, the long vertical plate is fitted with the vertical plate of the adjacent male rib plate, and the female rib hook plate is fitted with the male rib hook plate of the adjacent male rib plate; the second step is to bend the front end of the female rib hook plate of the female rib plate to wrap the sliding hook plate and the top end of the horizontal upper plate of the male rib plate; the third step is to bend along the connection between the male rib hook plate and the vertical plate of the male rib plate, bend 90°, and form a 360° lock seam; the fourth step is to use a biting machine to bend the straight edge part of the 360° lock seam toward the male rib plate side by another 50-70°.

[0040] Figure 8 This is a partial enlarged view of the structure of the connection part of two metal roof panels. In this embodiment, the straight edge part is bent 60°, which not only greatly increases the bite tightness of the panel type, but also increases the difficulty of the panel type to be disengaged when affected by wind, thereby greatly improving the wind resistance performance.

[0041] Example 2

[0042] A standing seam metal roof panel, the structure of which is substantially the same as that of the first embodiment, except that the front end of the male rib hook plate 13 used in the present embodiment is also bent inwardly to form a male rib plate reinforcement edge 14 with a hook-shaped structure, and the front end of the female rib hook plate 23 is also bent inwardly to form a female rib plate reinforcement edge 24 with a hook-shaped structure, such as Figure 9 , 10 As shown. Through the design of the reinforced edge, the mechanical strength of the roof panel itself can be further improved during use due to the edge wrapping design. On the other hand, it can also protect the ends of the roof panel from being reduced in service life due to wear. Thirdly, it can also improve the sealing performance and safety performance. Adding a reinforced small edge can not only solve the problem of the edge wave of the board, but also solve the overall strength of the board after the board is bitten, and enhance the wind resistance of the board.
