Description

Technical Field

[0001] The utility model relates to the field of PVC wall panels, in particular to a fire-proof and flame-retardant PVC wall panel. Background Art

[0002] PVC wall panels perform well in terms of fire resistance and flame retardancy. Their material has been specially treated to have good flame retardancy and can usually meet the B1 fire retardancy standard. This means that when a fire occurs, PVC wall panels can effectively slow the spread of the fire and buy valuable time for personnel evacuation and fire rescue. At the same time, PVC wall panels produce less toxic smoke during the combustion process, which helps reduce the harm of fire to people. Therefore, it is suitable for places that pay attention to fire safety, such as schools, hospitals, shopping malls, etc.

[0003] The inventors of this application have found the following problems in practical use:

[0004] During the installation and use of existing PVC wall panels, most of them are installed and fixed by splicing them end to end and fastening them with screws. However, there is a problem in the installation. Specifically, in order to improve the convenience of splicing, traditional PVC wall panels are usually in the form of direct insertion. Considering the strength of the splicing structure, some products will set blocks and slots on the inside. Through the deformation of the PVC wall panels, the blocks are snapped into the inside of the slots. The splicing structure between these wall panels on the market still has the problem of unstable connection structure between adjacent PVC wall panels. Therefore, the inventor urgently needs to design a PVC wall panel with a stable splicing structure to cope with the current unstable splicing structure of PVC wall panels.

[0005] Therefore, it is necessary to provide a fire-retardant PVC wallboard to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the present invention is that the current splicing structure of PVC wall panels is unstable. In view of the above-mentioned defects of the prior art, a fire-resistant and flame-retardant PVC wall panel is provided.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: a fire-retardant PVC wall panel, comprising a first wall panel and a second wall panel, wherein a first snap-on module and a second snap-on module are respectively provided on both sides of the first wall panel and the second wall panel, and the opposite sides of the first wall panel and the second wall panel are snap-on connected through the first snap-on module and the second snap-on module, the first snap-on module comprises a fixing plate, and a snap-on groove is formed between one side of the fixing plate and the wall panel, the second snap-on module comprises a snap block, and the cross-section of the snap block is a "J"-shaped structure.

[0008] By adopting the above technical solution, the second wall panel is placed next to the first wall panel at an angle of 30 degrees. This angle design facilitates the smooth alignment and insertion of the buckle block into the buckle groove of the first wall panel. Then, by slowly moving the second wall panel, it is rotated around the axis of the buckle block. During this process, the buckle block, due to its unique "J"-shaped structure, can gradually and tightly engage with the buckle groove, thereby ensuring a stable connection between the first wall panel and the second wall panel.

[0009] It is further provided that the buckle block is buckled with the buckle groove, and the corners of the buckle block are in an arc-shaped structure.

[0010] By adopting the above technical solution, the corners of the buckle block are set to an arc-shaped structure, which plays an important guiding role in the splicing process. When the buckle block is inserted into the buckle groove, the arc-shaped corners can reduce friction and resistance, making the buckle process smoother and avoiding jamming or damage caused by sharp corners.

[0011] It is further provided that a limiting block is fixedly provided on one side of the fixing plate, and a limiting groove which is opposite to and fits with the limiting block is formed on one side of the buckle block.

[0012] By adopting the above technical solution, accurate positioning is ensured during the splicing process. When the buckle block of the second wall panel is inserted into the buckle groove of the first wall panel, the fit between the limit groove and the limit block provides a second stable support point for the wall panel, effectively preventing the wall panel from shifting during the splicing process and ensuring the accuracy and stability of the splicing.

[0013] It is further provided that a plurality of mounting grooves are equidistantly provided on the surface of the fixing plate for providing screw mounting points for the first wall panel, the second wall panel and the wall.

[0014] By adopting the above technical solution, through these preset installation slots, installers can accurately position and tighten the screws to ensure a stable connection between the wall panel and the wall, effectively preventing the wall panel from falling off or loosening due to external forces.

[0015] It is further provided that a plurality of cavities are formed at equal intervals on the inner sides of the first wall panel and the second wall panel.

[0016] By adopting the above technical solution, compared with traditional solid wall panels, this design with a cavity makes the wall panels lighter, easier to transport and install while maintaining sufficient structural strength, thereby reducing construction difficulty and cost.

[0017] It is further provided that a plurality of structural blocks are equidistantly provided on the back of the first wall panel and the second wall panel for providing an adhesive connection structure with an external wall.

[0018] By adopting the above technical solution, a stable and reliable adhesive foundation is provided for the connection between the wall panel and the external wall. The presence of the structural block increases the surface area and roughness of the back of the wall panel, allowing the adhesive to adhere more firmly to the wall panel, thereby improving the bonding strength between the wall panel and the wall and ensuring the stable installation of the wall panel.

[0019] It is further provided that the surfaces of the first wall panel and the second wall panel are coated with a flame retardant coating, and the outer sides are affixed with a flame retardant film.

[0020] By adopting the above technical solution, the flame-retardant coating can effectively prevent the spread of flames and reduce the spread of fire, thus buying valuable time for personnel evacuation and fire fighting and rescue. At the same time, the flame-retardant film serves as another layer of protective barrier, further enhancing the flame-retardant effect of the wall panels, allowing the wall panels to maintain stability for a longer period of time when encountering a fire, thereby reducing the damage caused by the fire to the building.

[0021] Compared with the related art, the fire-retardant PVC wallboard provided by this utility model has the following advantages:

[0022] Beneficial effects:

[0023] The utility model provides a fire-proof and flame-retardant PVC wall panel. When the second wall panel is spliced ​​with the first wall panel through a first snap-joining module and a second snap-joining module, the snap block on one side of the second wall panel is accurately placed into the snap-joining groove on one side of the first wall panel. Then, the second wall panel is slowly moved to rotate around the position of the snap block. During this process, the snap block can gradually and tightly snap into the snap-joining groove due to its "J"-shaped structural design, which not only improves the stability of the splicing structure, but also the "J"-shaped end is larger in size than the traditional card block form, further enhancing the structural strength of the snap-joining.

[0024] The utility model provides a fire-proof and flame-retardant PVC wall panel, which adopts limit blocks and limit grooves to further ensure the connection stability between the wall panels. At the same time, in this process, the interlocking of the limit grooves and the limit blocks plays a vital auxiliary role. They constitute the second installation support point, which not only further strengthens the connection between the wall panels, but also effectively prevents the wall panels from being displaced in the horizontal or vertical direction after splicing, thereby greatly improving the splicing structural stability of the two adjacent wall panels. Specifically, the precise cooperation between the limit grooves and the limit blocks is equivalent to adding an additional locking mechanism between the wall panels. When the buckle block is inserted into the buckle groove and the initial buckle is completed, the mutual engagement of the limit grooves and the limit blocks provides an additional support point for the wall panel. This support point can disperse the external pressure on the wall panel and enhance the overall wind pressure resistance and earthquake resistance of the wall panel.

DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0031] Example 1:

[0032] like Figure 1 As shown, a fire-retardant PVC wall panel of the present invention includes a first wall panel 101 and a second wall panel 102. The first wall panel 101 and the second wall panel 102 are respectively provided with a first buckle module 2 and a second buckle module 3 on both sides, and the first wall panel 101 and the second wall panel 102 are buckled together on opposite sides through the first buckle module 2 and the second buckle module 3. The first buckle module 2 includes a fixing plate 201, and a buckle groove 202 is formed between one side of the fixing plate 201 and the wall panel. The second buckle module 3 includes a buckle block 301. The cross section of the buckle block 301 is a "J"-shaped structure. The second wall panel 102 is placed next to the first wall panel 101 at an angle of 30 degrees. The angle design facilitates the smooth alignment and insertion of the buckle block 301 into the buckle groove 202 of the first wall panel 101. Subsequently, the second wall panel 102 is slowly moved to rotate around the axis of the buckle block 301. During this process, the buckle block 301, due to its unique "J"-shaped structure, can gradually and tightly engage with the buckle groove 202, thereby ensuring a firm connection between the first wall panel 101 and the second wall panel 102. Compared with traditional card blocks, the "J"-shaped end design of the buckle block 301 is not only larger in size and enhances the structural strength of the buckle, but also effectively avoids the difficulty of engaging due to deformation during the traditional splicing process of PVC wall panels, significantly improving the convenience and efficiency of splicing.

[0033] like Figure 2 、 Figure 3As shown, the buckle block 301 is buckled with the buckle groove 202, and the corners of the buckle block 301 are arc-shaped. The corners of the buckle block 301 are set to an arc-shaped structure, which plays an important guiding role in the splicing process. When the buckle block 301 is inserted into the buckle groove 202, the arc-shaped corners can reduce friction and resistance, making the buckling process smoother and avoiding jamming or damage caused by sharp corners. At the same time, the arc-shaped structure also enhances the contact area between the buckle block 301 and the buckle groove 202, disperses stress, and improves the firmness and durability of the buckle.

[0034] Example 2:

[0035] like Figure 3 As shown, a limiting block 203 is fixedly provided on one side of the fixing plate 201, and a limiting groove 302 is formed on one side of the buckle block 301, which is opposite to and fits with the limiting block 203, ensuring precise positioning during the splicing process. When the buckle block 301 of the second wall panel 102 is inserted into the buckle groove 202 of the first wall panel 101, the fit between the limiting groove 302 and the limiting block 203 provides a second stable support point for the wall panel, effectively preventing the displacement of the wall panel during the splicing process, ensuring the accuracy and stability of the splicing. At the same time, the use of the limiting block 203 and the limiting groove 302 also significantly enhances the structural strength after splicing. The close fit between them forms a stable connection point, which can disperse and withstand various external forces that the wall panel may be subjected to during use, such as wind, vibration, etc., thereby extending the service life of the wall panel.

[0036] like Figure 4 As shown, a plurality of mounting grooves 6 are equidistantly provided on the surface of the fixing plate 201 for providing screw mounting points for the first wall panel 101, the second wall panel 102 and the wall. Through these preset mounting grooves 6, the installer can accurately position and tighten the screws to ensure a stable connection between the wall panel and the wall, effectively preventing the wall panel from falling off or loosening due to external forces. At the same time, the equidistant mounting grooves 6 also ensure the uniformity and consistency of the wall panel installation. Each mounting groove 6 is arranged at a fixed spacing, so that the screws are more evenly distributed on the wall panel, thereby avoiding the situation where the local force on the wall panel is too large or too small due to uneven distribution of screws.

[0037] like Figure 2 、 Figure 3 As shown, a plurality of cavities 4 are formed at equal intervals on the inner sides of the first wall panel 101 and the second wall panel 102. Compared with traditional solid wall panels, this design with cavities 4 makes the wall panels lighter while maintaining sufficient structural strength, and is convenient for transportation and installation, thereby reducing construction difficulty and cost. At the same time, the presence of multiple cavities 4 also enhances the sound insulation and heat insulation performance of the wall panels. The cavities 4 can effectively block the propagation path of sound and heat, forming a natural sound insulation and heat insulation barrier.

[0038] like Figure 3 As shown, a plurality of structural blocks 5 are equidistantly arranged on the back of the first wall panel 101 and the second wall panel 102, which are used to provide an adhesive connection structure with the external wall, providing a stable and reliable adhesive basis for the connection between the wall panel and the external wall. The presence of the structural blocks 5 increases the surface area and roughness of the back of the wall panel, so that the adhesive can be more firmly attached to the wall panel, thereby improving the bonding strength between the wall panel and the wall, ensuring the stable installation of the wall panel. At the same time, the design of equidistant distribution of multiple structural blocks 5 also ensures the uniformity and consistency of the adhesive connection. Each structural block 5 bears a part of the role of the adhesive, and jointly shares the connection pressure between the wall panel and the wall, avoiding the connection weakness caused by uneven distribution of the adhesive.

[0039] like Figure 4 As shown, the surfaces of the first wall panel 101 and the second wall panel 102 are coated with a flame retardant coating 701, and the outer sides are coated with a flame retardant film 702. The flame retardant coating 701 can effectively prevent the spread of flames and reduce the spread of fire, thereby buying valuable time for personnel evacuation and fire fighting and rescue. At the same time, the flame retardant film 702 serves as another layer of protective barrier, further enhancing the flame retardant effect of the wall panel, so that the wall panel can maintain stability for a longer time when encountering a fire, reducing the damage to the building caused by the fire. In addition, the combined use of the flame retardant coating 701 and the flame retardant film 702 also improves the weather resistance and durability of the wall panel. They can resist the erosion of external factors such as ultraviolet rays, moisture, and corrosion, extend the service life of the wall panel, and reduce the cost of maintenance and replacement.

[0040] In practice, when the first wall panel 101 and the second wall panel 102 need to be spliced ​​and installed, first, the first wall panel 101 is pre-installed on the surface of the wall, and the first wall panel 101 is fixed to the wall by screwing the screws through the installation slot 6 at a certain time. Figure 3 As shown, the second wall panel 102 is placed at an angle of 30 degrees to the first wall panel 101, and then the buckle block 301 on one side of the second wall panel 102 is placed into the buckle groove 202 on one side of the first wall panel 101. After that, the second wall panel 102 is slowly moved, causing the second wall panel 102 to rotate around the position of the buckle block 301 until the buckle block 301 is gradually buckled with the buckle groove 202. Because the buckle block 301 is a "J"-shaped structure, the splicing structural stability of the first wall panel 101 and the second wall panel 102 can be improved. In this splicing embodiment, the "J"-shaped end of the buckle block 301 is larger than the traditional card block form, which can further improve its buckling structural strength and avoid the deformation and clamping process of the traditional splicing form of PVC wall panels, thereby improving its splicing convenience. During the splicing, the limit groove 302 is buckled with the limit block 203, providing a second installation support point, further improving the splicing structural stability of the two adjacent wall panels.

[0041] The advantages of this technical solution in practical applications include but are not limited to the following:

[0042] 1. The buckle block, due to its "J"-shaped structure, can gradually and tightly buckle with the buckle groove, which not only improves the stability of the splicing structure, but also the "J"-shaped end is larger in size than the traditional card block, further enhancing the structural strength of the buckle;

[0043] 2. When the buckle block is inserted into the buckle groove and the initial buckling is completed, the mutual engagement between the limit groove and the limit block provides an additional support point for the wall panel, further enhancing the structural strength of the splicing between the first wall panel and the second wall panel.
