Description

Technical Field

[0001] The utility model relates to the technical field of PVC wall panels, in particular to a PVC wall panel for building thermal insulation. Background Technique

[0002] The thermal insulation wall panel is, to put it simply and understandably, a board used for building thermal insulation and is often used in construction projects. The building thermal insulation exterior wall panel is a board pasted on the exterior wall of a building.

[0003] The thermal insulation wall panel has the advantages of light weight, high strength, multiple environmental protections, thermal insulation, sound insulation, moisture regulation by respiration, fire prevention, rapid construction, and reduction of wall cost. The prior art discloses a building thermal insulation and decoration wall panel with the application number: 201520759510.7, in particular to a wall panel, which includes a composite board body. The composite board body includes an outer color steel plate, an inner color steel plate, and a fireproof and thermal insulation material filled between the outer color steel plate and the inner color steel plate. Convex interfaces and concave interfaces that cooperate with each other are respectively arranged on both sides of the composite board body. A bolt head receiving groove and a bolt hole are arranged on the convex interface. A sealing strip is arranged on one side of the concave interface close to the outer color steel plate, and a notch and a nut receiving groove are arranged on one side of the concave interface close to the inner color steel plate. However, the prior art is slightly insufficient in indoor thermal insulation, resulting in relatively fast dissipation of indoor temperature. In order to improve the actual thermal insulation performance of the wall panel, the utility model provides a PVC wall panel for building thermal insulation. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related art to a certain extent. For this reason, an object of the utility model is to provide a PVC wall panel for building thermal insulation, which has the characteristics of light weight, simple structure, good thermal insulation performance, quick connection between wall panel bodies, and stable structure.

[0005] The technical solution is as follows:

[0006] A PVC wall panel for building thermal insulation includes a wall panel body. The wall panel body is hollowly arranged. The interior of the wall panel body is divided into upper and lower inner cavities by a partition layer, namely an a-side inner cavity and a b-side inner cavity. The a-side inner cavity is filled with a thermal insulation filler, and a heat insulation layer is arranged in the b-side inner cavity. The heat insulation layer is distributed in a wavy shape. A positioning groove is arranged on one side of the wall panel body. Both ends of the positioning groove are open. Correspondingly, a matching positioning block protrudes on the other side of the wall panel body.

[0007] Further, the thermal insulation filler is selected as thermal insulation cotton.

[0008] Further, the heat insulation layer is selected as a foam board.

[0009] Furthermore, the upper side and the lower side of the heat insulation layer are respectively fixedly connected to the top and the bottom of the inner cavity on the b side. A plurality of heat insulation cavities are formed between the top of the heat insulation layer and the top of the inner cavity on the b side, and between the bottom of the heat insulation layer and the bottom of the inner cavity on the b side. The heat insulation cavities are evenly distributed.

[0010] Advantages of the utility model:

[0011] By hollowing out two inner cavities in the wallboard main body and respectively arranging heat preservation fillers and a heat insulation layer in the two inner cavities, the heat preservation and heat insulation properties of the heat preservation fillers and the heat insulation layer effectively improve the heat preservation and heat insulation properties of the utility model.

[0012] By hollowing out two inner cavities in the wallboard main body and selecting relatively light heat preservation cotton and foam board to be arranged in the two inner cavities, the mass of the wallboard of the utility model is effectively made lighter. With the positioning grooves and positioning blocks symmetrically arranged on both sides of the wallboard main body, the wallboard of the utility model is easier to splice and install.

[0017] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0018] Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model and should not be construed as a limitation to the utility model.

[0019] Please refer to Figures 1 to 2As shown in the figure, a PVC wall panel for building thermal insulation includes a wall panel main body 1. The wall panel main body 1 is hollowly arranged. The interior of the wall panel main body 1 is divided into upper and lower inner cavities by a partition layer 102, namely an a-side inner cavity and a b-side inner cavity. The a-side inner cavity is filled with a thermal insulation filler 2, and the thermal insulation filler 2 is selected as thermal insulation cotton. The b-side inner cavity is provided with a heat insulation layer 3, and the heat insulation layer 3 is selected as a foam board. The heat insulation layer 3 is distributed in a wavy shape. The upper side and the lower side of the heat insulation layer 3 are respectively fixedly connected to the top and the bottom of the b-side inner cavity. A plurality of heat insulation cavities 103 are formed between the top of the heat insulation layer and the top of the b-side inner cavity and between the bottom of the heat insulation layer 3 and the bottom of the b-side inner cavity. The heat insulation cavities 103 are evenly distributed. One side of the wall panel main body 1 is provided with a positioning groove 101. Both ends of the positioning groove 101 are open. Corresponding to the positioning groove 101, a matching positioning block 104 protrudes on the other side of the wall panel main body 1.

[0020] According to the above scheme, the wall panel of the present utility model effectively improves the heat preservation and heat insulation properties of the wall panel of the present utility model by arranging two inner cavities in the wall panel main body 1, filling the a-side inner cavity with the thermal insulation filler 2 selected as thermal insulation cotton, and arranging the wavy heat insulation layer 3 made of a foam board in the b-side inner cavity. Moreover, the foam board also has a certain sound insulation performance, which can further improve the practicality of the wall panel of the present utility model.

[0021] Arranging two inner cavities in the wall panel of the present utility model can also effectively reduce the self-weight of the wall panel main body. Moreover, fillers such as thermal insulation cotton and foam board are light in weight, which can make the wall panel main body 1 more convenient for installation. At the same time, with the positioning grooves 101 and positioning blocks 104 symmetrically arranged on both sides of the wall panel main body 1, the wall panel main bodies 1 of the present utility model are also convenient for positioning connection and splicing assembly.

[0022] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
