Description

Technical Field

[0001] The present invention belongs to the technical field of building decoration, and particularly relates to a prefabricated wall panel system and an installation method thereof. Background Art

[0002] As a new type of building material, the wood-plastic board has the advantages of waterproof, moisture-proof, environmental protection, recyclable, good fire performance, etc., and has excellent physical stability and mechanical properties. However, the current construction of wood-plastic boards mainly uses the method of directly nailing self-tapping screws on the steel structure keel. This method requires a large number of nails, which not only easily damages the wood-plastic board and reduces its secondary utilization efficiency, but also results in a low degree of assembly due to excessive nailing, seriously affecting the wall aesthetics. With the continuous improvement of the construction industry's pursuit of environmental protection, efficiency and aesthetics, there is an urgent need for a new prefabricated wall panel system and installation method to solve these problems. Summary of the Invention

[0003] Aiming at the problems and deficiencies existing in the above-mentioned prior art, the present invention provides a prefabricated wall panel system and an installation method thereof. Through innovative structural design and installation process, the damage to the wood-plastic board is reduced, the degree of assembly and the wall aesthetics are improved, and at the same time, the secondary utilization efficiency of the wood-plastic board is increased to meet the development needs of the construction industry.

[0004] The present invention is achieved by the following technical solutions:

[0005] A prefabricated wall panel system includes square tubes, outer plate connectors and horizontal wood-plastic boards. The square tubes are in a vertical state and fixed to the wall, and at least two square tubes are provided. The outer plate connectors are fixed to the square tubes and at least two are provided along the extension direction of the square tubes. The outer plate connectors include a bottom plate and two horizontal buckles and two vertical buckles fixed to the bottom plate. The two horizontal buckles and the two vertical buckles are distributed in a cross shape. The horizontal wood-plastic boards are installed between adjacent two square tubes, and at least two horizontal wood-plastic boards are provided in the extension direction of the square tubes. The horizontal wood-plastic boards include a horizontal exterior board and a horizontal strip board, an upper bearing convex board and a lower insertion concave board located inside the horizontal exterior board. The horizontal strip board is snapped to the horizontal buckle. Between two adjacent horizontal wood-plastic boards up and down, the lower insertion concave board of the upper horizontal wood-plastic board is inserted into the upper bearing convex board of the lower horizontal wood-plastic board, so that the two horizontal exterior boards are spliced into a whole. The basic structure of the prefabricated wall panel system is constructed. The square tubes provide support, the outer plate connectors provide interfaces for the installation of the wood-plastic boards, and the horizontal wood-plastic boards are spliced by snapping and inserting, greatly improving the degree of assembly and reducing the damage to the boards caused by nailing.

[0006] Furthermore, the prefabricated wall panel system further includes vertical wood-plastic panels, which are installed between two adjacent horizontal wood-plastic panels on the same wall surface. The vertical wood-plastic panel includes a vertical exterior panel and a vertical clamping strip panel located inside the vertical exterior panel. The vertical clamping strip panel is clamped to the vertical snap fastener, and the inner wall of the vertical exterior panel abuts against the outer wall of the horizontal exterior panel. This improves the wall structure, enhances the wall tightness and aesthetics, enriches the wall assembly methods, and meets the requirements of different wall layouts.

[0007] Furthermore, square tubes are installed at the ends of the outer wall of the wall. Outer panel connectors are installed on both the outer wall and the side wall of the square tube located at the end of the wall. The prefabricated wall panel system further includes end wood-plastic panels, which are installed on the outer panel connectors on the side wall of the square tube located at the end of the wall. The end wood-plastic panel includes an L-shaped exterior panel, a vertical clamping strip panel fixed to the inside of the L-shaped exterior panel, and a transition angle plate connecting the L-shaped exterior panel. The vertical clamping strip panel is clamped to the vertical snap fastener, the inner wall of the L-shaped exterior panel abuts against the outer wall of the horizontal exterior panel, and the transition angle plate abuts against the end of the wall. This effectively decorates and protects the end of the wall, enhances the stability and aesthetics of the corner part, and solves the installation problem at the corner.

[0008] Furthermore, the wall has an inner corner. The prefabricated wall panel system further includes an inner corner connector and an inner corner wood-plastic panel. The inner corner connector includes a triangular rib plate body, two inner corner plates fixed to the triangular rib plate body, and an inner corner snap fastener. The triangular rib plate body is an isosceles triangle. An inner corner plate is provided at each base angle of the triangular rib plate body. The inner corner snap fastener is located at the apex angle of the triangular rib plate body. The angle between the two inner corner plates is the same as the angle of the inner corner of the wall. Two triangular weight-reducing holes are provided inside the triangular rib plate body. The inner corner wood-plastic panel includes two inner corner exterior panels and an inner corner clamping strip panel connected to each other. The angle between the two inner corner exterior panels is the same as the angle of the inner corner of the wall. The inner corner clamping strip panel is fixed to the connection of the two inner corner exterior panels and is located on the symmetry plane of the two inner corner exterior panels. The inner corner clamping strip panel is clamped to the inner corner snap fastener, and the inner wall of the inner corner exterior panel abuts against the outer wall of the horizontal exterior panel. Specifically designed for the inner corner of the wall, it realizes the sealing and decoration at the inner corner, adapts to the installation requirements of the inner corner wall surface, and improves the aesthetics and practicality of the inner corner part.

[0009] Further, the wall has an outer corner. The prefabricated wall panel system further includes an outer corner connector and an outer corner wood-plastic board. The outer corner connector includes a cylindrical main body, two outer corner boards fixed to the cylindrical main body, and an outer corner snap. The two outer corner boards are tightly fixed to the outer corner of the wall, and the included angle between the two outer corner boards is the same as the angle of the outer corner of the wall. An arc-shaped groove is formed at the connection of the cylindrical main body and the two outer corner boards. The outer corner snap is fixed to the side of the outer corner board away from the arc-shaped groove. The outer corner wood-plastic board includes two outer corner decorative boards connected to each other, a rib plate main body connecting the two outer corner decorative boards, and an outer corner strip board. The included angle between the two outer corner decorative boards is the same as the angle of the outer corner of the wall. The outer corner strip board is located on the symmetry plane of the two outer corner decorative boards. The outer corner strip board is snapped to the outer corner snap, and the inner wall of the outer corner decorative board abuts against the outer wall of the horizontal decorative board. It meets the installation requirements of the outer corner of the wall, realizes sealing and decoration at the outer corner, and ensures the aesthetics and stability of the outer corner part.

[0010] Further, screw strip grooves are formed on the upper bearing convex plate. The extending direction of the screw strip grooves is the same as the extending direction of the horizontal wood-plastic board, and the screw strip grooves penetrate through the horizontal wood-plastic board. During the installation process, fixing screws can be installed in the screw strip grooves as needed to further enhance the connection stability between the horizontal wood-plastic board and the square pipe, and ensure the firmness of the entire wall panel system.
