Description

Technical Field

[0001] The utility model relates to the technical field of metal buildings, in particular to a fixing device based on a metal roof panel. Background Art

[0002] Metal roofing refers to a roofing form that uses metal sheets as roofing materials and combines the structural layer and the waterproof layer into one. There are many types of metal sheets, including galvanized sheets, aluminum-zinc sheets, aluminum alloy sheets, aluminum-magnesium alloy sheets, titanium alloy sheets, copper sheets, stainless steel sheets, etc. Metal sheet roofing has various forms and is used in large public buildings, factories, warehouses, residences, etc.

[0003] In the prior art, metal roof panels are mostly fixed by fasteners or self-tapping screws. The sealant around the self-tapping screws is prone to aging, while the fastener connection method has the problem of poor fixing strength and the connection seam is easy to expand after being stressed, which cannot meet the actual needs of users. Therefore, we propose a fixing device based on metal roof panels to solve the above problems. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Refer to Figure 1-2 , a fixing device based on a metal roof panel, including a panel body 1, a folding edge is arranged at the edge of the panel body 1, and further includes a limiting component for clamping the folding edge;

[0019] The limiting component includes a left clamping plate 2 and a right clamping plate 3. Sinking grooves 4 are formed on the sides of the left clamping plate 2 and the right clamping plate 3 close to each other. A push block 5 is slidably connected in the sinking grooves 4. Threaded holes 6 are formed in the left clamping plate 2, and set screws 7 are arranged in the threaded holes 6. A wedge-shaped block 8 is fixedly connected to the side of the push block 5 close to the set screw 7. A through hole 9 for the set screw 7 to pass through is formed in the right clamping plate 3, and the right clamping plate 3 is fixedly connected to a support plate 10 by the set screw 7;

[0020] Based on the above design, the limiting assembly uses the left clamping plate 2 and the right clamping plate 3 to clamp the folding edges of two adjacent panel bodies 1 or the folding edges of a single panel body 1, and then screws the fixing bolt 7 into the threaded hole 6. During the process of screwing the fixing bolt 7 in, the fixing bolt 7 abuts against the wedge block 8, driving the push block 5 to move toward the direction of the panel body 1, thereby squeezing and deforming the part of the folding edge located in the sink 4. After that, after the tightening bolt passes through the through hole 9, the fixing bolt 7 is tightened with a nut to complete the fixation of the panel body. Although this design will cause the folding deformation to occur, it has a better fixing effect on the panel body 1. At the same time, there is no need to splice the folding edges of the two adjacent panel bodies 1 with more effort, and the installation operation is more convenient. In addition, in this design, the allowable range of processing error for the folding edge is larger. At the same time, during the transportation of the panel body 1, the deformation of the folding edge will not have a significant impact on the subsequent assembly.

[0021] Furthermore, a pressure strip 11 is fixedly connected to one side of the left clamping plate 2 close to the right clamping plate 3, and a clearance groove is provided on the side wall of the right clamping plate 3 close to the pressure strip 11. In this design, the pressure strip 11 cooperates with the clearance groove to squeeze and deform part of the folding edge between the left clamping plate 2 and the right clamping plate 3, so that the gap between the folding edge and the left clamping plate 2 and the right clamping plate 3 is smaller, thereby avoiding water seepage between the folding edges on two adjacent panel bodies 1, and at the same time, the limiting component can also better fix the folding edge.

[0022] Furthermore, the inner wall of the trough 4 away from the push block 5 is fixedly connected with a conical block 12, and the conical block 12 is set against the folding edge. The setting of the conical block 12 can make the folding edge, after being squeezed by the push block 5, use the conical block to extrude a more complex shape on the folding edge, so that the folding edge is completely stuck in the trough 4 and cannot be separated.

[0023] Furthermore, the folding edge includes a bending edge 13 fixedly connected to the panel body 1, and one end of the bending edge 13 far from the main body is provided with a special-shaped edge 14, wherein the special-shaped edge 14 is arc-shaped or spiral-shaped;

[0024] In this design, the bent edge 13 is bent at 90° to assemble the two panel bodies 1 together, while the special-shaped edge 14 is used to be squeezed and deformed in the limiting component to ensure the fixing effect of the limiting component on the panel body 1.

[0025] Furthermore, grooves are provided at one ends of the left clamping plate 2 and the right clamping plate 3 away from the set bolt 7, and a sealing strip 15 is fixedly connected in the grooves. The sealing strip 15 is provided to seal the gap between the clamping plate and the panel body 1, preventing water vapor from entering the sunk groove 4. Since the folding edge is easily damaged by the extrusion of the push block 5 on the anti-rust structure on the surface of the panel body 1, the sealing strip 15 is provided for waterproofing to avoid the rust of the folding edge located in the sunk groove 4, which may cause the fixing effect of the limiting component to deteriorate.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
