Description

Technical Field

[0001] This utility model relates to the field of wall insulation structure technology, specifically a building wall insulation structure. Background Technology

[0002] Thermal insulation walls play a vital role in buildings. They effectively reduce heat exchange between indoors and outdoors, improve building energy efficiency, lower heating and cooling costs, and also provide some sound insulation, enhancing living comfort. EPS (Expanded Polystyrene) moldings are commonly used for exterior wall decoration, offering advantages such as lightweight, thermal insulation, and waterproofing, enhancing both the aesthetics and functionality of the walls.

[0003] A search revealed that utility model patent CN205617736U discloses an EPS line, which includes a polystyrene foam board base layer at the bottom and a coating surface layer. An adhesive mesh fabric layer is provided between the polystyrene foam board layer and the coating layer. An anti-crack mortar layer is provided between the adhesive mesh fabric layer and the coating layer. A flame retardant layer is provided between the anti-crack mortar layer and the mesh fabric layer.

[0004] However, existing EPS trim is prone to problems such as crooked installation and poor adhesion during installation. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a building wall insulation structure that solves the problems of existing EPS lines being easily installed crookedly and not firmly adhered.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building wall insulation structure, comprising a wall, an adhesive layer bonded to the surface of the wall, EPS lines bonded to the surface of the adhesive layer, an intermediate layer bonded to the surface of the EPS lines, a decorative layer coated on the surface of the intermediate layer, and anchor nails embedded inside the EPS lines, the anchor nails penetrating the adhesive layer and embedded in the wall.

[0007] Preferably, the anchor nail is integrally formed with a tapered pin, which is embedded in the wall. The tapered pin increases the strength of the bond between the EPS line and the wall.

[0008] Preferably, the EPS line has multiple grooves on the side closest to the wall, and the adhesive layer fills the grooves. The grooves increase the bonding strength between the EPS line and the adhesive layer.

[0009] Preferably, the adhesive layer is a flexible crack-resistant primer layer. By selecting an adhesive layer with a flexible crack-resistant primer, gaps on the wall surface can be filled, the flatness of the EPS lines can be improved, and they can better bond with the wall.

[0010] Preferably, the intermediate layer is a fiberglass mesh layer. By bonding a layer of fiberglass mesh to the surface of the EPS line, the surface strength of the EPS line can be increased.

[0011] Preferably, the decorative layer is an anti-UV topcoat layer. As the outermost layer of the EPS line, the decorative layer serves an aesthetic purpose, while the use of an anti-UV topcoat prevents the EPS line from oxidizing due to prolonged exposure to sunlight.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model significantly improves the bonding strength between EPS lines and the wall by using a double fixing design with tapered pins and an adhesive layer, effectively preventing the lines from falling off or shifting. Moreover, the groove on the back of the EPS line and the interlocking design of the adhesive layer further increase the contact area and adhesion, ensuring long-term stability. In addition, the flexible crack-resistant primer, as an adhesive layer, can not only fill the gaps on the wall surface, but also adapt to minor deformations of the wall, reducing the risk of cracking.

[0014] 2. This utility model involves setting an intermediate layer and a decorative layer on the outer surface of EPS lines. The decorative layer uses an anti-UV topcoat, which effectively blocks ultraviolet rays from sunlight and external erosion, preventing fading and embrittlement caused by oxidation or aging of the EPS lines, thus extending their service life. Simultaneously, this topcoat gives the wall a rich color and texture, meeting diverse decorative needs. Furthermore, the fiberglass mesh fabric, as the intermediate layer, prevents surface cracking, ensuring a smooth and aesthetically pleasing decorative layer. The overall structure balances functionality and aesthetics. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 A building wall insulation structure includes a wall 1. An adhesive layer 2, 1-2 mm thick, is bonded to the surface of the wall 1. EPS (Expanded Polystyrene) strips 3 are bonded to the surface of the adhesive layer 2. An intermediate layer 5 is bonded to the surface of the EPS strips 3. A decorative layer 6 is coated on the surface of the intermediate layer 5. Anchor nails 4 are embedded inside the EPS strips 3, penetrating the adhesive layer 2 and embedded in the wall 1. Multiple anchor nails 4 are provided and spaced apart along the length of the EPS strips 3. A tapered pin 41 is integrally formed on each anchor nail 4 and embedded in the wall 1. The tapered pin 41 increases the bonding strength between the EPS strips 3 and the wall 1. Multiple grooves 31 are formed on the side of the EPS strips 3 closest to the wall 1, and the adhesive layer 2 fills the grooves 31. The grooves 31 further increase the bonding strength between the EPS strips 3 and the adhesive layer 2.

[0020] Please see Figure 1-2 The adhesive layer 2 is a flexible crack-resistant primer layer. By using the flexible crack-resistant primer in the adhesive layer 2, gaps on the surface of the wall 1 can be filled, improving the flatness of the EPS line 3 and allowing for better bonding with the wall 1. The intermediate layer 5 is a fiberglass mesh layer. By bonding a layer of fiberglass mesh to the surface of the EPS line 3, the surface strength of the EPS line 3 can be increased. The decorative layer 6 is a UV-resistant topcoat layer. As the outermost layer of the EPS line 3, the decorative layer 6 serves an aesthetic purpose, while the use of a UV-resistant topcoat prevents the EPS line 3 from oxidizing due to prolonged exposure to sunlight.

[0021] The specific implementation process of this utility model is as follows: First, use a roller or scraper to evenly apply the flexible crack-resistant primer adhesive layer 2 to the surface of the wall 1, ensuring complete coverage of the base layer and filling of small cracks. Then, attach the EPS line 3 to the surface of the wall 1, adjust its position to make it flat and aligned. At this time, the EPS line 3 is bonded to the adhesive layer 2, and the anchor nails 4 on the EPS line 3 are embedded in the pre-drilled holes in the wall 1. At the same time, a small amount of adhesive layer 2 will also seep into it. Then, apply polymer mortar evenly to the surface of the EPS line 3, and then press in the intermediate layer 5, ensuring that there are no hollows or wrinkles. After the intermediate layer 5 is completely dry, apply the UV-resistant topcoat, i.e., the decorative layer 6, by spraying or rolling. This completes the overall construction.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
