Description

Wood-plastic composite wallboard Technical Field The utility model belongs to the technical field of wallboards, and particularly relates to a wood-plastic composite wallboard. Background The traditional wood-plastic wallboard adopts an integral extrusion molding process, and a hollow channel is arranged in the middle, so that the strength is mainly improved, and a certain sound insulation effect can be attached at the same time, but the effect is not ideal. Disclosure of Invention The utility model aims at solving the problems in the prior art, and provides a wood-plastic composite wallboard which has the characteristic of good sound insulation effect. The aim of the utility model can be achieved by the following technical scheme: a wood-plastic composite wallboard comprising: The first plate body is provided with a first arched part, a plurality of extrusion parts are arranged in the first arched part, and one end of the first plate body is provided with a tenon structure; The second plate body is provided with a second arched part corresponding to the first arched part, the first arched part and the second arched part form a cavity, the extrusion part is positioned in the cavity, the other end of the first plate body is combined with the second plate body to form a female tenon structure, and the female tenon structure corresponds to the male tenon structure; And the soundproof cotton is arranged at the bottom of the second arched part and is fixed by extrusion of the extrusion part. In the wood-plastic composite wallboard, the first board body and the second board body are connected through screws, and the first board body is exposed at the outer side position. In the wood-plastic composite wallboard, the screw penetrates through the second board body, the soundproof cotton and is fixedly connected with the extrusion part. In the wood-plastic composite wallboard, the extrusion parts are arranged at the bottom of the first arch part at equal intervals. In the wood-plastic composite wallboard, the two ends of the first board body are provided with the first connecting grooves, the two ends of the second board body are provided with the second protrusions, and the two second protrusions can be inserted into the two first connecting grooves. Compared with the prior art, the application has the following advantages: According to the application, the first arched part of the first plate body and the second arched part of the second plate body form a corresponding structure, so that the integral structural stability of the wallboard can be effectively improved, the plurality of extrusion parts in the first arched part are positioned in the cavity, the supporting forces in the first plate body and the second plate body are enhanced, the dispersed stress structure is formed by matching with the second arched part, the deformation risk under the impact of external force is reduced, the split design of the first plate body and the second plate body is used for facilitating the installation of soundproof cotton, the soundproof cotton can be fully covered, the specially arranged soundproof cotton is positioned at the bottom of the second arched part and is extruded and fixed through the extrusion parts, the soundproof cotton can be ensured to be stably filled in the cavity, and the obvious soundproof effect is improved.
