[0015] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, apparently, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments, based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0016] EMBODIMENT

[0017] Please refer to Figure 1 、 Figure 2 and Figure 3 , the utility model provides a technical scheme: a new zinc-aluminum-magnesium color steel profiled steel plate wall panel, including steel plate main body 1, the surface of steel plate main body 1 is equipped with anticorrosion plating 11, specifically, anticorrosion plating 11 is zinc-aluminum-magnesium plating, zinc-aluminum-magnesium plating is composed of primary zinc phase, zinc / zinc-magnesium binary eutectic phase and zinc-aluminum-magnesium ternary eutectic phase, forms a dense, effective barrier to prevent corrosion factor penetration, steel plate main body 1 is pressed to form with several recesses 2, the both ends of steel plate main body 1 are equipped with first buckling edge 3 and second buckling edge 5 respectively, first buckling edge 3 is L-shaped, and second buckling edge 5 is hook-shaped, and first buckling edge 3 and second buckling edge 5 are adapted, and the bottom surface of first buckling edge 3 is equipped with bent end 4, and bent end 4 is lapped on second buckling edge 5 to form water guide.

[0018] The top surface of second buckling edge 5 is equipped with first limiting hook 6, and first limiting hook 6 is adapted with first buckling edge 3.

[0019] The oblique side of first buckling edge 3 is equipped with second limiting hook 7, and second limiting hook 7 is adapted with second buckling edge 5.

[0020] Bent end 4 is 180 ° edge curl compaction.

[0021] In the embodiment, the zinc-aluminum-magnesium coating is composed of primary zinc phase, zinc / zinc-magnesium binary eutectic phase and zinc-aluminum-magnesium ternary eutectic phase, forms a dense barrier effectively preventing corrosion factors from penetrating, and greatly improves the corrosion resistance. The magnesium component in the zinc-aluminum-magnesium coating is conducive to promoting the formation of a fine protective film with very stable state and meticulous structure. The protective film generates on the surface of the coating and maintains a film-shaped covering layer, thereby exerting excellent corrosion resistance. Even after the coating is cut or damaged, the coating components are continuously dissolved to form a dense protective film mainly composed of zinc hydroxide, basic zinc chloride and magnesium hydroxide, etc., which has obvious inhibitory effect on corrosion. The zinc-aluminum-magnesium metal substrate is selected due to its excellent corrosion resistance, light weight, high strength and good processability. Through special alloy ratio, the wind pressure resistance and snow load capacity are further improved.

[0022] Through cooperation of the first buckling edge 3, the bent end 4 and the second buckling edge 5, a water guide is formed at the lap joint of the two steel plate bodies 1, the water guide cuts off the capillary pipeline caused by the adhesion of the two steel plates, and the water column in the water guide also balances the atmospheric pressure difference between the indoor and outdoor to prevent rainwater from penetrating into the indoor. The bent end 4 is arranged at the lap joint and is rolled and compacted by 180 degrees, so that the non-layered cutout is not exposed to the outdoor, and the corrosion resistance is enhanced.

[0023] The lap joint mode of the scheme is relatively simple and easy to operate. The construction personnel only need to ensure that the first buckling edge 3 and the second buckling edge 5 of the two steel plate bodies 1 are tightly attached and form the required cavity, which helps to improve the construction efficiency and reduce the construction cost.
