Technical Field

[0003] A search revealed a weather-resistant, heavy-duty anti-corrosion, and crack-resistant flooring structure with announcement number CN217924631U. This structure includes a sand and gravel base layer, upon which two concrete base layers (one and two) are poured. A crack-resistant reinforcing layer connects the two concrete base layers. The lower and upper reinforcing wire mesh layers are fixedly connected at both ends by a connecting frame. Several intersecting inclined reinforcing ribs (one and two) connect the lower and upper reinforcing wire mesh layers, forming a cavity between them. An anti-corrosion base layer is provided on the concrete base layer. This structure is simple, easy to use, and effectively increases the overall structural strength of the flooring, preventing cracking. It also provides excellent anti-corrosion and moisture-proof performance.

[0004] For very large floor structures, when pouring concrete, the steel cage is directly used in conjunction with the concrete material. Since there are relatively few structural layers, dampness and cracking are likely to occur later, shortening the service life.

[0005] Therefore, a moisture-proof device for preventing cracking in ultra-large area flooring is proposed to address the above problems. Utility Model Content

[0011] Preferably, the concrete material covers the outer part of the reinforcing cage, and the bottom of the concrete pouring layer is in contact with the surface of the waterproof coating layer.

[0012] Preferably, the crack-resistant protective layer includes a floor paint coating sprayed onto the surface of the concrete pouring layer, and the surface of the floor paint coating is sprayed with an anti-corrosion protective layer.
