Description

Technical Field

[0001] The utility model relates to the field of construction, and more specifically, to a composite wall panel member. Background Art

[0002] A composite wall panel is a kind of wall decoration material composed of a variety of different materials, aiming to provide more functions and performances to meet the diverse needs of building walls. As a high-performance interior partition board for buildings, compared with traditional brick and tile building materials, the composite wall panel not only has higher strength and lighter weight, but also has the characteristics of fast construction and convenient installation. Therefore, it is deeply welcomed by consumers and has become a wall material more commonly used by owners in modern buildings.

[0003] When installing the composite wall panel, multiple splicings are usually carried out. However, the sealing performance at the splicing joints is weak. When it is winter, the temperature of the wall is low, but the indoor air temperature is high. The gas easily contacts the wall surface through the splicing joints, and it is easy to condense and mildew on the wall.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0018] The following combines the drawings and embodiments to describe the utility model in detail.

[0019] The composite wall panel member, as Figure 1 and Figure 2 shown, includes a board body. The board body includes a moisture-proof layer 1, a surface layer 2, and a thermal insulation layer 3. The moisture-proof layer 1 is located between the surface layer 2 and the thermal insulation layer 3. By providing the moisture-proof layer 1, the board body has a moisture-proof effect. And connection slopes 4 are provided at both ends of the moisture-proof layer 1. When adjacent moisture-proof layers 1 are attached, the connection slopes 4 can increase the contact surface of the moisture-proof layer 1, improving the sealing effect of the moisture-proof layer 1. One end of the surface layer 2 is integrally formed with a clamping portion 6, and a clamping groove 7 is provided at the end of the surface layer 2 facing away from the clamping portion 6. The clamping groove 7 is used to accommodate the clamping portion 6 of another board body. By providing the clamping portion 6 to be clamped into the clamping groove 7 of an adjacent board body, the connection between adjacent board bodies can be improved.

[0020] As Figure 1 shown, sealing strips 5 are bonded to both ends of the thermal insulation layer 3. The sealing strips 5 are made of ethylene propylene diene monomer rubber material. Thus, when the board body is installed, after adjacent thermal insulation layers 3 are attached, the adjacent sealing strips 5 are attached, increasing the sealing performance of the thermal insulation layer 3 after the board body is installed. The cross-section of the clamping portion 6 is triangular, and the cross-sectional area of the clamping groove 7 is the same as the cross-sectional area of the clamping portion 6. Thus, when the board body is installed, it is convenient for the clamping portion 6 to enter the clamping groove 7. Two fixing holes 8 are provided on the thermal insulation layer 3. Thus, screws can pass through the fixing holes 8 to be connected to the wall surface, thereby improving the connection strength between the board body and the wall surface.

[0021] As Figure 1 andFigure 2 As shown, the heat insulation layer 3 is an extruded board, so that while the heat insulation layer 3 has good heat insulation performance, it also has good strength. The surface layer 2 is a calcium silicate board, so that the surface layer 2 has good hardness and moisture resistance. The moisture-proof layer 1 is made of expanded perlite material, and expanded perlite can block moisture, so that the moisture-proof layer 1 has good water-blocking performance.

[0022] Working process: When installing the wall panel, the installer first cuts one end of the panel body with the clamping part 6 until the surface layer 2, the moisture-proof layer 1 and the heat insulation layer 3 at this end are aligned. Then the installer aligns the heat insulation layer 3 of this panel with the wall surface, and then the installer presses the aligned side tightly against the corner of the wall, and the heat insulation layer 3 fits against the wall surface. Then the installer screws in screws at the position of the fixing holes 8 of the heat insulation layer 3 to connect the panel body to the wall surface. Then the installer takes out another panel body and aligns the clamping part 6 on the surface layer 2 of this panel body with the clamping groove 7 of the previous panel body. Then the installer fits these two panel bodies together. During this process, the connecting inclined surface 4 also fits, and the sealing strip 5 on the heat insulation layer 3 also fits. Then the installer uses the same method to fix the heat insulation layer 3 to the wall surface to complete the connection between the two panel bodies.

[0023] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
