Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to an exterior wall panel. Background Art

[0002] At present, exterior wall panels are mainly divided into flat exterior wall panels, L-shaped exterior wall panels and U-shaped exterior wall panels. Figure 7 As shown, the existing L-shaped exterior wall panel mainly includes an L-shaped metal decorative panel 10, which is composed of a metal panel 1 and metal side panels 2, and an insulation panel 3 and insulation side panels 4. The insulation panel 3 is fixed to the metal panel 1 with glue 100, and the insulation side panels 4 are also fixed to the metal side panels 2 with glue 100. Although the glue fixing method can quickly and conveniently fix the insulation panel, insulation side panels and L-shaped metal decorative panel together, it still has the following shortcomings in actual application:

[0003] First, after gluing, it needs to be left for 4 to 5 hours to set to ensure that the glue is dry and solidified, to avoid displacement between the boards, and to ensure the stability and reliability of the gluing. However, this is very time-consuming and affects production efficiency.

[0004] Secondly, after being used for a period of time, the glue will age, making it easy for the insulation panel, insulation side panel and L-shaped metal decorative panel to separate, resulting in an unreliable connection and a major safety hazard.

[0005] Third, the glue contains a certain amount of volatile organic compounds such as formaldehyde and benzene, which is very environmentally unfriendly and will pollute the environment and affect the health of production workers.

[0006] Therefore, in view of the above-mentioned deficiencies of the existing exterior wall panels, it is very necessary to design an exterior wall panel that does not require glue to fix and bond, so as to better meet people's application needs. Utility Model Content

[0007] The purpose of the present utility model is to solve the above-mentioned problems and shortcomings and to provide an exterior wall panel. The exterior wall panel is fixedly connected together with an L-shaped metal decorative panel through a sliding connection superimposed elastic locking structural design. Not only is it firmly installed and will not loosen, eliminating safety hazards, but it is also fixed without screws and does not require the aid of tools, which greatly improves the convenience of assembly. After assembly, it does not need to be placed and shaped, which is very convenient, fast, time-saving and efficient. It does not need to be fixed with glue, and the use of glue is completely abandoned, which is more environmentally friendly and avoids pollution to the environment and affects the health of production workers.

[0008] The technical solution of the present utility model is implemented as follows: an exterior wall panel, including an L-shaped metal decorative panel composed of a metal panel and a metal side panel, and an insulation panel and insulation side panels, wherein the metal panel and the metal side panels are respectively provided with T-shaped slide rails, and the insulation panel and the insulation side panels are respectively provided with T-shaped slide seats, the insulation panel is slidably connected to the metal panel through the sliding cooperation between the T-shaped slide seat and the T-shaped slide rail, and the insulation side panels are also slidably connected to the metal side panels through the sliding cooperation between the T-shaped slide seat and the T-shaped slide rail; the two T-shaped slide rails are also respectively provided with limiting lock holes, and the two T-shaped slide seats are also respectively provided with elastic retractable locking parts that can be embedded in the limiting lock holes to lock the insulation panel, the insulation side panels and the L-shaped metal decorative panel together.

[0009] Preferably, a buckling protrusion and a buckling groove that are buckled and connected to each other are further provided between the insulation side panel and the insulation panel.

[0010] Preferably, the length A of the T-shaped slide rail of the metal panel is the same as the width B of the thermal insulation panel, and the length C of the T-shaped slide rail of the metal side panel is the same as the width D of the thermal insulation side panel.

[0011] Preferably, the elastic telescopic locking member includes a locking pin and a spring, and the T-shaped slide is provided with a guide hole.

[0025] like Figure 1 and Figure 2As shown, the exterior wall panel described in the present invention includes an L-shaped metal decorative panel 10 integrally composed of a metal panel 1 and a metal side panel 2, and a thermal insulation panel 3 and a thermal insulation side panel 4. In order to achieve the purpose proposed by the present invention, the metal panel 1 and the metal side panel 2 are respectively provided with a T-shaped slide rail 5, and the thermal insulation panel 3 and the thermal insulation side panel 4 are respectively provided with a T-shaped slide seat 6. The thermal insulation panel 3 is slidably connected to the metal panel 1 through the sliding cooperation between the T-shaped slide seat 6 and the T-shaped slide rail 5, and the thermal insulation side panel 4 is also slidably connected to the metal side panel 2 through the sliding cooperation between the T-shaped slide seat 6 and the T-shaped slide rail 5; as shown Figure 5 and Figure 6 As shown, the two T-shaped slide rails 5 are respectively provided with a limit lock hole 51, and the two T-shaped slide seats 6 are respectively provided with an elastic retractable locking member 7 that can be embedded in the limit lock hole 51 to lock the insulation panel 3, the insulation side panel 4 and the L-shaped metal decorative panel 10 together. The present invention uses a structural design of sliding connection superimposed with elastic locking to fix the insulation panel 3, the insulation side panel 4 and the L-shaped metal decorative panel 10 together. Not only is the installation firm and will not get loose, eliminating safety hazards, but it is also screw-free and tool-free, greatly improving the convenience of assembly. After assembly, there is no need to place it for shaping, which is very convenient, fast, time-saving and efficient. It also does not need to be fixed with glue, completely abandoning the use of glue, which is more environmentally friendly, avoids pollution to the environment, and avoids affecting the health of production workers. Through the elastic expansion and contraction effect of the elastic expansion and contraction locking piece 7, when the T-shaped slide 6 slides, the elastic expansion and contraction locking piece 7 shrinks under the pressure of the T-shaped slide rail 5 to avoid affecting the sliding of the T-shaped slide 6. When the elastic expansion and contraction locking piece 7 moves to the limiting lock hole 51 with the T-shaped slide 6, the elastic expansion and contraction locking piece 7 is no longer pressed by the T-shaped slide rail 5 and elastically extends and embeds into the limiting lock hole 51, thereby achieving the locking purpose.

[0026] During actual installation, Figure 5 and Figure 6 As shown, the insulation panel 3 is first installed on the metal panel 1, and then the insulation side panel 4 is installed on the metal side panel 2, so that one end of the insulation side panel 4 abuts against the back of the insulation panel 3. Of course, the insulation side panel 4 can also be installed on the metal side panel 2 first, and then the insulation panel 3 is installed on the metal panel 1, so that one end of the insulation panel 3 abuts against the back of the insulation side panel 4.

[0027] like Figure 2 As shown, the length A of the T-shaped slide rail 5 of the metal panel 1 is the same as the width B of the insulation panel 3, and the length C of the T-shaped slide rail 5 of the metal side panel 2 is the same as the width D of the insulation side panel 4. This can limit the sliding range of the insulation panel 3 and the insulation side panel 4 without affecting their assembly.

[0028] like Figure 2As shown, the T-shaped slide rail 5 is a T-shaped convex track structure, and the T-shaped slide seat 6 is a slide seat structure with a T-shaped slide groove, and the T-shaped slide groove can be slidably mounted on the T-shaped slide rail 5.

[0029] In actual application, the thermal insulation panel 3 and the thermal insulation side panels 4 are both polyurethane rigid foam boards. The polyurethane material has very good thermal insulation and waterproof properties, thereby improving the thermal insulation and waterproof properties of the exterior wall panel.

[0030] In order to enhance the structural strength of the insulation panel 3 and the insulation side panel 4, Figure 3 and Figure 4 As shown, a metal frame 8 is embedded within each of the insulation panel 3 and the insulation side panels 4, and the T-shaped slide 6 is disposed on the metal frame 8. Specifically, the T-shaped slide 6 is secured to the metal frame 8 by welding. In actual use, the metal frame 8 is a mesh-like metal frame, which allows the polyurethane foam material to be easily coated on the metal frame 8, thereby allowing the metal frame 8 to be embedded in the insulation panel 3 or the insulation side panels 4.

[0031] In order to further improve the stability of the overall assembly of the exterior wall panels, such as Figure 5 and Figure 6 As shown, a snap-fitting protrusion 81 and a snap-fitting groove 82 that are snap-fitted together are provided between the insulation side panel 4 and the insulation panel 3. Specifically, the snap-fitting protrusion 81 is provided on the insulation side panel 4, and the snap-fitting groove 82 is provided on the insulation panel 3. Of course, the installation positions of the snap-fitting protrusion 81 and the snap-fitting groove 82 can also be interchanged. By increasing the assembly connection structure between the insulation side panel 4 and the insulation panel 3, the stability of the connection between the insulation side panel 4 and the insulation panel 3 can be enhanced, thereby making the overall assembly stability of the exterior wall panel better and preventing it from loosening. More specifically, the snap-fitting protrusion 81 is integrally formed on the metal frame 8 of the insulation side panel 4, and the snap-fitting groove 82 is provided on the metal frame 8 of the insulation panel 3, and a through hole that passes through to the snap-fitting groove 82 is provided on the outer wall of the insulation panel 3, so that the snap-fitting protrusion 81 can penetrate into the interior of the insulation panel 3 and can be snap-fitted on the snap-fitting groove 82.

[0032] In order to further improve the structure of the elastic telescopic locking member 7, make it simple, scientific and reasonable, and easy to manufacture, as Figure 6 As shown, the elastically retractable locking member 7 includes a locking pin 71 and a spring 72. The T-shaped slide 6 is provided with a guide hole 61. The spring 72 and the locking pin 71 are sequentially embedded in the guide hole 61. As a result, under the elastic pressure of the spring 72, one end of the locking pin 71 extends out of the guide hole 61 and is embedded in the position-limiting locking hole 51. The provision of the spring 72 ensures that the locking pin 71 always remains embedded in the position-limiting locking hole 51 and does not become loose, thereby ensuring the reliability of the locking connection.

[0033] like Figure 6 As shown, the T-shaped slide 6 is further provided with a housing box 63 with a housing cavity 62. The guide hole 61 extends into the housing cavity 62, and the locking pin 71 and spring 72 are disposed in the housing cavity 62. The provision of the housing box 63 expands the space on the T-shaped slide 6 for accommodating the elastically retractable locking member 7, ensuring that the locking pin 71 and spring 72 have sufficient space for expansion and contraction. Furthermore, when the metal frame 8 is embedded in the insulation panel 3 or insulation side panel 4, the polyurethane foam material will not be poured into the housing cavity 62 and the guide hole 61, thereby preventing the expansion and contraction of the locking pin 71 and spring 72 from being affected. Specifically, the housing box 63 is fixed to the T-shaped slide 6 by welding.

[0034] In order to make the assembly of exterior wall panels more convenient and quick, Figure 6 As shown, the locking pin 71 is also provided with a guiding bevel 711. This eliminates the need to manually press the locking pin 71 during the sliding installation of the insulation panel 3 and insulation side panel 4. As the locking pin 71 slides over the T-shaped slide rail 5, it automatically retracts, making installation of the insulation panel 3 and insulation side panel 4 more convenient and quick. Specifically, the guiding bevel 711 of the locking pin 71 on the insulation panel 3 is located on the side facing the metal side panel 2, while the guiding bevel 711 of the locking pin 71 on the insulation side panel 4 is located on the side facing the metal panel 1.

[0035] In order to reduce the gap between the insulation panel 3, the insulation side panel 4 and the L-shaped metal decorative panel 10, as shown in FIG. Figure 2 As shown, the insulation panel 3 and the insulation side panels 4 are both provided with a storage groove 30, and the T-shaped slide 6 is embedded in the storage groove 30. This allows the surface of the insulation panel 3 to be in contact with the back of the metal panel 1, and the surface of the insulation side panel 4 to be in contact with the back of the metal side panel 2, thereby achieving a closer contact between the insulation panel 3, the insulation side panels 4 and the L-shaped metal decorative panel 10, and improving the stability of the connection. Specifically, the front surface of the T-shaped slide 6 of the insulation panel 3 is flush with the front surface of the insulation panel 3, and the front surface of the T-shaped slide 6 of the insulation side panel 4 is flush with the front surface of the insulation side panel 4.
