[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In one embodiment, a metal wall panel is provided, combining Figure 1 As shown, the metal wall panel includes a wall panel body 1, which is pressed by metal materials, and the metal materials include aluminum, iron, copper, etc., but are not limited to these materials. A first wave peak portion 11 and a second wave peak portion 12 are respectively provided on both sides of the wall panel body 1. The first wave peak portion 11 and the second wave peak portion 12 are symmetrical, and a V-shaped wave trough portion 13 is provided between the first wave peak portion 11 and the second wave peak portion 12. A sub-mouth 14 is provided on one side of the bottom of the first wave peak portion 11. The sub-mouth 14 is a plate-shaped plug formed by folding inwardly at the lower end of the first wave peak portion 11, and a female mouth 15 is provided on one side of the bottom of the second wave peak portion 12. The wall panel body 1 is located at the bottom of the first wave peak portion 11 and is bent to one side to form the sub-mouth 14. A B-shaped bend 16 is provided on the outer side of the wall panel body 1 at the bottom of the second wave peak portion 12, and the female mouth 15 is located at the inward bending of the B-shaped bend 16, as shown in FIG. Figure 1 As shown, the female opening 15 is a gradually narrowing opening shape, and the shape of the sub-opening 14 can be inserted into the female opening 15 and ensure that the sub-opening 14 can be firmly inserted.

[0022] Compared with the metal corrugated sheet currently used in buildings, the metal siding is provided with a first wave crest portion 11 and a second wave crest portion 12 on both sides of the siding body 1, and then a V-shaped wave trough portion 13 is provided between the first wave crest portion 11 and the second wave crest portion 12. This structure reduces the number of bent corrugations compared with the current sheet material, and can save sheet material to the greatest extent. In addition, the V-shaped wave trough portion 13 between the first wave crest portion 11 and the second wave crest portion 12 is a large-angle trough, which is not easy to accumulate dust, and is convenient for self-cleaning by washing with rainwater on rainy days. The first wave crest portion 11 and the second wave crest portion 12 are symmetrical, which is convenient for stacking and transportation. When the metal siding is in use, a plurality of metal sidings of this shape are connected end to end in sequence to form an outer wall surface, and adjacent metal sidings are connected by a socket connection of a sub-mouth 14 and a female mouth 15, which is convenient to install and leaves no gaps in the outer wall surface, which is more beautiful, and rainwater will not penetrate into the outer wall surface.

[0023] Further, in another embodiment, Figure 1As shown, the metal wall panel is provided with a plate screw fixing plate section 2 on the outside of the B-shaped bend 16 on the wall panel body 1, a screw groove 21 is provided on the plate screw fixing plate section 2, and a flange 22 is provided on the edge of the plate screw fixing plate section 2. The wall panel body 1 and the plate screw fixing plate section 2 are formed by pressing a metal material into one body. By providing the plate screw fixing plate section 2, the plate screw fixing plate section 2 can be covered by the first wave crest portion 11 of the adjacent metal wall panel, and the screw groove 21 provided on the plate screw fixing plate section 2 can also be covered. When the metal wall panel is installed, it is fixedly connected to the building frame by screwing in the screw groove 21. Since the screw groove 21 is covered, it is prevented from being wetted by rainwater and rusting. Providing a flange 22 on the edge of the plate screw fixing plate section 2 can prevent the installer from being cut and the side of the metal wall panel from being exposed and rusting.

[0024] Further, in another embodiment, Figure 1 As shown, a plurality of reinforcing ribs 17 are provided on the plate body on both sides of the V-shaped trough portion 13 of the metal wall panel. The reinforcing ribs 17 are wavy structures formed on the plate body on both sides of the V-shaped trough portion 13. By providing the reinforcing ribs 17, the strength of the metal wall panel can be improved, and no local deformation will occur during installation.

[0025] Further, in another embodiment, Figure 1 As shown, the angle α between the plate body on both sides of the V-shaped trough 13 of the metal wall plate and the horizontal plane is 9° to 11°, preferably 10°. The angle is conducive to ensuring that rainwater is washed away, and on the other hand, it is conducive to ensuring the strength of the metal wall plate.

[0026] Further, in another embodiment, Figure 1 As shown, the intersection of the bottom corner plate body of the V-shaped trough portion 13 of the metal wall panel is treated with a smooth arc, and the two top corners of the first wave peak portion 11 and the second wave peak portion 12 and other bent parts are also treated with a smooth arc. The peak spacing D2 between the first wave peak portion 11 and the second wave peak portion 12 is 350 mm, and the peak height H of the first wave peak portion 11 and the second wave peak portion 12 is 35 mm. The wall panel body 1 is located at the bottom of the first wave peak portion 11 and is bent 90° to the right to form a sub-mouth 14. The folding length D1 of the inward bending of the B-shaped bend 16 to form the mother mouth 15 is 17 mm, and the bending radius of the inward bending of the B-shaped bend 16 is 2 mm. The effective width D of the wall panel body 1 is 370 mm. The effective width refers to the distance between the sub-mouth 14 and the mother mouth 15. These specific dimensions can be set according to on-site usage requirements. There is a 10 mm height difference between the top of the first crest portion 11 and the second crest portion 12 and the lower end of the V-shaped trough portion 13 , so there is enough space on the lower side. When installing the rock wool board, it is not easy to cause local protrusion of the V-shaped trough portion 13 and affect the overall flatness and shape of the metal wall.

[0027] The metal wall panel is pressed from a metal plate with a width of 300mm to 800mm during processing. The structure of the metal wall panel is specially designed to maximize the utilization rate of the plate without affecting the rigidity and strength of the metal plate.

[0028] Combination Figure 2-4 As shown, in one embodiment, a metal wall is also provided, which is formed by connecting a plurality of the above-mentioned metal wall panels. Figure 2 As shown, the sub-port 14 of the metal wall plate on the right is inserted into the female port 15 of the metal wall plate adjacent to the left side to achieve the connection between the two metal wall plates. Figure 3 and Figure 4 As shown, the metal wall is vertically laid on the wall frame by the above-mentioned metal wall panels, and the wall frame is provided with a vertical frame composed of wall vertical purlins 34 and wall horizontal purlins 35 on the brick wall foundation 36. The metal wall 3 in this embodiment is formed by connecting adjacent metal wall panels end to end in sequence, and the metal wall 3 is laid on the outside of the vertical frame. A gutter 31 is provided on the inside of the vertical frame, and the gutter 31 is located on the inside of the bottom of the parapet 33 for drainage. A roof frame composed of roof purlins 38 is provided on the inside of the gutter 31, and a roof panel 32 is provided on the roof frame. A flashing 37 is provided on the outside of the bottom of the metal wall 3. The metal wall 3 is fixed by self-tapping screws at the screw grooves 21 of each metal wall panel. The position of the self-tapping screws only penetrates one metal wall panel and the position of the self-tapping screws is completely hidden on the inner side of another metal wall panel, which will not cause erosion and water seepage by rainwater, prevents rust and damage of the plate, and increases the service life of the plate. The corrugated plate after installation has a smooth and beautiful appearance and is easy to clean.
