Composite floor

Disclosed is a composite floor, comprising four floor boards of a plate face layer, a ductile layer, a rigid layer and an elastic layer from top to bottom, and the bottom layer is flexible and can be compounded on the ground. The firstly layer generally adopts plant material, and deformation exists certainly, the second layer is an elastic board made by flexible inorganic material, and can perfectly buffer the force produced during deformation of the first layer, meanwhile, the second layer is elastic and can digest the deformation of the first layer to the elastic material, and the third layer is a rigid layer, and enhances the intensity and equilibrating action of the floor by the inorganic board, and has strong adhesive force and adaptability. The ductile material can prevent the ground humidity from rising, and can be adhered and flatly placed on different grounds. The utility model solves the deformation problem of the floor concisely, and combines different materials into one body in the meanwhile, so t
