A composite environmental protection decorative board

Abstract

The invention discloses a composite environmental protection decorative board, which comprises a composite board main body, the composite board main body comprises a wear-resistant layer, a reinforced stability layer, a balance layer and a noise reduction layer, a plurality of moisture-proof bases are fixedly connected to the bottom of the composite board main body, and the composite board main body A pair of connecting bars are fixedly connected to the side walls, the connecting bars are in a "U" shape, a mortise block is fixedly connected to the bottom of the side wall of the connecting bar, and one end of the mortise block is provided with a mortise plate; compared with the prior art, the present invention has As the use time of the board increases, the board will deform, so that both ends of the connecting strip can be squeezed, and the tenon block can be pushed to move inside the tenon groove. The tenon block is cut by the tapered end under the action of mutual extrusion, and the cut part of the tenon block is pressed to both ends under the action of the inclined plate, so that the tenon block can be clamped in the tenon groove. Slowing down the deformation of the main body of the composite board after long-term use can increase the service life of the board.

Description

technical field [0001] The invention relates to the technical field of environmental protection building materials, in particular to a composite environmental protection decorative board. Background technique [0002] A composite board refers to a board composed of two or more materials. In fact, the concept and production method of composite panels are also different for panels of different materials. In daily life, metal composite panels, wood-plastic composite panels and glass fiber reinforced plastic composite panels are often used. [0003] With the improvement of people's living standards, most of the decorative floors in the house use the floor, and the installation of the floor is to buckle the small strips one by one to form a whole, but the wood board will deform or bulge after long-term use, resulting in small pieces of board The looseness of the fastening between them will not only affect the beauty of the indoor floor, but also cause certain safety hazards, an...

Problems solved by technology

[0003] With the improvement of people's living standards, flooring is mostly used as the decorative floor in the house. The installation of the floor is to buckle the small strips one by one to form a whole, but the wooden boards will be deformed or bulged after long-term use, resulting in small boards. The fastening between them is loose, which not only affects the appearance of the indoor floor, but also creates certain safety hazards. Moreover, it is very troublesome to replace the floor. Environmentally friendly decorative panels are used to solve the above problems
