[0002] Composite plates are generally divided into: metal composite plates, wood composite plates, color steel composite plates, rock wool composite plates, etc. A composite plate is a plate composed of different materials with different functions in layers. For example, a three-in-one plate for roofing, which consists of concrete, a foam insulation layer and a surface waterproof layer, and a sandwich panel is also a kind of composite plate.

[0003] After retrieval, the existing patent (Publication No.: CN221646240U) discloses a composite plate for preventing deformation, which includes a first plate body for support, a left clamping block, a wear-resistant layer, a reinforcing rib and an anti-corrosion honeycomb core. The outer side of the left clamping block is clamped and connected with a second plate body. The inner side of the wear-resistant layer is fixedly connected with a decorative layer. The upper and lower ends of the reinforcing rib are closely attached with an adhesive layer. The upper and lower ends of the calcium silicate fiber fireproof layer are closely attached with an adhesive layer. The upper and lower ends of the anti-corrosion honeycomb core are provided with reinforcing ribs. This composite plate for preventing deformation can prevent the plate from deforming. If it is accidentally hit by a heavy object during use, the plate will not deform. It can quickly join the plates together, and the plates can be fixed without using cement. It can be fireproof and waterproof. When a fire occurs on a single floor, it can prevent the fire from spreading to the lower floor, or if the household accidentally spills water, it can prevent the floor from seeping.
