Description

Technical Field

[0001] This invention relates to the field of building decoration materials technology, specifically a wall panel installation structure and its installation method. Background Technology

[0002] Current wall panel installations mostly employ on-site adhesive bonding, but this method suffers from drawbacks such as low efficiency, poor reliability, and insufficient sealing. On one hand, on-site adhesive application involves brushing, pressing, and curing, a cumbersome process that leads to a long construction period. On the other hand, traditional adhesive layers are thin and rigid, lacking cushioning and leveling capabilities, and are highly dependent on the flatness of the substrate. When there are unevenness deviations in the wall surface, localized point contact easily forms between the wall panel and the wall, resulting in insufficient effective bonding area and an inability to compensate for gaps, easily leading to hollowing, loosening, or even detachment. Furthermore, the joints between panels typically lack effective sealing structures, allowing moisture to easily penetrate and affecting the lifespan of both the wall panel and the wall structure.

[0003] Therefore, there is an urgent need to provide a wall panel installation structure that is quick to install, highly adaptable to wall substrates, has a buffering and leveling function, and excellent waterproof performance. Summary of the Invention

[0004] The existing wall panel installation methods, as mentioned above, mostly employ on-site adhesive bonding, which suffers from low efficiency, poor reliability, and insufficient sealing. The technical solution adopted by this invention to address these problems is as follows: A wall panel installation structure includes two or more wall panels. Each wall panel has a locking structure and an adhesive assembly on its back. The locking structure includes a raised locking strip and a locking groove that engages with the raised locking strip. The adhesive assembly has a substrate, adhesive on both sides of the substrate, and release paper covering the outside of the adhesive. Adjacent wall panels are locked together by the raised locking strip and the locking groove. After the release paper is removed, the adhesive assembly is used to adhere the wall panel to the wall surface.

[0005] Furthermore, the locking structure is provided on all four sides of the wall panel, and at least two sets of adhesive components are provided and arranged in parallel.

[0006] Furthermore, the thickness of the adhesive component is between 0.5-4mm, forming a buffer space between the wall panel and the wall surface.

[0007] Furthermore, the substrate includes one of polyester, polyvinyl chloride, polypropylene, polyethylene, polyurethane, acrylic foam, acrylic foam, polyethylene foam, and EVA foam, and the adhesive includes one of acrylic adhesive and rubber-based adhesive.

[0008] Furthermore, the initial tack of the adhesive component is greater than 22N, the peel force is greater than 35N, and the adhesive component can withstand a load of 2kg per square inch at 40°C for more than 72 hours and a load of 3kg per square inch at 25°C for more than 48 hours.

[0009] Furthermore, the adhesive assembly includes a first double-sided adhesive and a first fastener attached to the wall, a second double-sided adhesive attached to the wall panel, and a second fastener connected to the second double-sided adhesive.

[0010] Furthermore, the thickness of the raised locking bar is between 1.5 and 2.5 mm, the height of the raised locking bar is between 3.5 and 4.5 mm, and the end of the raised locking bar is provided with a bevel or an arc surface.

[0011] Furthermore, the lock groove includes a lock groove opening into which the protruding lock bar extends, a first extension on one side of the lock groove opening, and a second extension on the other side of the lock groove opening. The extension length of the first extension is greater than the extension length of the second extension. The second extension is provided with a guide surface. The protruding lock bar extends into the lock groove after abutting against the first extension and / or the second extension.

[0012] Furthermore, the raised locking bar has a first step on one side and opposite to the first extension, and a second step on the other side and abutting against the second extension. The thickness of the wall panel is between 3-8 mm, the thickness of the second step is between 1-2 mm, and a gap is formed between the top of the first step and the bottom of the first extension, with a gap height of between 0.5-1 mm.

[0013] Another object of the present invention is to provide an installation method for a wall panel mounting structure, applicable to the wall panel mounting structure described above, comprising the following steps: S1. Clean the wall surface and attach the adhesive components to the wall and / or wall panel; S2. After peeling off all the release paper, attach the wall panel to the wall and press it to make the adhesive components contact the wall. S3. Adjacent wall panels are interlocked through a locking structure to achieve splicing and overall leveling.

[0014] The beneficial effects of this invention are as follows: 1. The wall panel installation structure of the present invention uses an adhesive component with release paper pre-placed on the back of the wall panel. The adhesive component of the present invention has reliable bonding, and the locking structure can enhance the overall integrity and prevent warping and deformation. While ensuring a stable connection, it simplifies the on-site construction process.

[0015] 2. This invention is convenient and efficient to install, eliminating the need for on-site adhesive application and prolonged pressing for curing, thus greatly shortening the installation time. By utilizing a flexible colloid to provide a compression buffer space, this invention can absorb local height differences in the wall, ensuring full contact of the adhesive surface. The locking structure helps to level the wall panels, maintaining the overall flatness of the finish. The joints between the wall panels are physically sealed through small flat openings, thereby preventing moisture intrusion and improving the sealing performance of the joint area.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2 and Figure 6 The wall panel installation structure shown includes two or more wall panels 1. Each wall panel 1 is provided with a locking structure and an adhesive assembly 5 located on its back. The locking structure includes a raised locking strip 2 and a locking groove 3 that cooperates with the raised locking strip 2. The adhesive assembly 5 is provided with a substrate 51, adhesive 52 located on both sides of the substrate 51, and release paper 53 covering the outside of the adhesive 52. Adjacent wall panels 1 are locked together by the raised locking strip 2 and the locking groove 3. After the release paper 53 is removed, the adhesive assembly 5 is used to adhere the wall panel 1 to the wall surface 100.

[0025] The wall panel installation structure of this invention offers convenient installation, eliminating the need for on-site adhesive mixing and application; it allows for immediate peeling and pasting, significantly improving construction efficiency. Simultaneously, its adhesive components provide cushioning, reducing the requirements for wall surface flatness and achieving stress release, thus exhibiting high adaptability. Furthermore, the synergistic effect of mechanical locking and chemical bonding enhances the overall integrity of the wall panel, preventing deformation and improving its structural stability. In addition, its physical locking structure extends the moisture penetration path, improving waterproof and moisture-proof performance. It also possesses excellent sealing properties.

[0026] The wall panel installation structure of this invention simplifies on-site construction procedures by pre-installing an adhesive assembly with release paper on the back of the wall panel. During construction, there is no need for on-site mixing and application of adhesive; the wall panel is simply peeled off the release paper and adhered to the wall surface. Locking is achieved through the engagement of protruding locking strips and locking grooves between adjacent wall panels. This method reduces on-site wet work and helps shorten the installation time for a single wall panel.

[0027] Meanwhile, the mechanical engagement of the raised locking strip and the locking groove, together with the adhesive bonding of the back adhesive components, forms a mechanical locking structure, which helps to limit the relative displacement of the wall panel during the adhesive curing process. Combined with the adhesive force of the adhesive components, this reduces the risk of the wall panel loosening or falling off.

[0028] Furthermore, the interlocking structure creates a meshing effect at the joints of adjacent wall panels, increasing the penetration path length at the joints. Combined with the back adhesive layer, this helps improve the sealing performance of the joint area. The prefabricated adhesive components also help control the thickness and uniformity of the adhesive layer, reducing issues such as hollow areas or adhesion failures caused by uneven on-site adhesive application, thus improving the consistency of installation quality.

[0029] like Figure 1 and Figure 2 The wall panel installation structure shown has locking structures on all four sides of the wall panel 1, and at least two sets of adhesive components are provided and arranged in parallel.

[0030] Specifically, the wall panel installation structure of the present invention provides locking structures on all four sides of the wall panel, enabling a single wall panel to mechanically engage with adjacent wall panels in multiple directions. This helps to limit the relative displacement of the wall panels in the installation plane and reduce misalignment of the panel edges caused by local flatness deviations of the base layer or shrinkage of the adhesive layer, thereby improving the uniformity of the joint width at the joint of adjacent wall panels.

[0031] Meanwhile, the interlocking structure on all four sides forms a continuous interlocking interface after the wall panels are spliced, which increases the length of the penetration path at the joints. Combined with the sealing effect of the adhesive components on the back, it helps to reduce the possibility of moisture invading the interior of the wall from the joint area.

[0032] The adhesive components are set in at least two sets and arranged in parallel, so that the bonding area between the wall panel and the wall is distributed in multiple areas. This helps to disperse the stress generated by the self-weight of the wall panel and external loads, and reduces the risk of interface peeling due to local stress concentration in a single bonding area.

[0033] In addition, the parallel adhesive components can provide multiple support reference points for the wall panels during construction, which helps operators control the pasting posture of the wall panels, reduces the deflection of the panels due to insufficient initial adhesion during pressing and bonding, and helps improve the flatness of the wall surface after large-area paving.

[0034] Furthermore, such as Figure 5 As shown, the thickness of the adhesive component is between 0.5-4mm, and a buffer space 200 is formed between the wall panel 1 and the wall surface 100.

[0035] Specifically, after removing the release paper, the thickness of the adhesive assembly is set to 0.5-4mm, creating an adjustable buffer space between the wall panel and the wall surface. The wall panels of this invention interlock through a locking structure and utilize this buffer space to achieve overall leveling. When there are localized flatness deviations on the base wall surface, the adhesive within this thickness range can fill the gaps through deformation, helping to ensure an effective contact area between the back of the wall panel and the adhesive layer, reducing the risk of hollow areas caused by poor contact.

[0036] At the same time, the buffer space can absorb displacement stress caused by changes in ambient temperature or minor settlement of the wall, reducing the direct transmission of stress to the wall panel surface, thereby reducing the possibility of wall panel cracking or adhesive layer peeling.

[0037] Furthermore, a certain adhesive layer thickness provides the adhesive with room for flow and deformation, which is beneficial for the adhesive to wet the micropores on the substrate surface and improve the bonding stability of the interface. This thickness setting also helps to form a physical barrier layer between the wall panel and the wall, which helps to improve moisture penetration and sound transmission.

[0038] Optionally, in some embodiments, the thickness of the adhesive component can be selected to be between 0.5 and 4 mm, and its thickness is not limited to 1 mm, 2 mm, 3 mm, or 4 mm. A thickness of 0.5 mm is suitable for scenarios where the wall surface is very smooth. The thickness of the adhesive component can be considered as the sum of the substrate thickness and the thickness of the two adhesive layers.

[0039] Furthermore, the substrate 51 includes one of polyester, polyvinyl chloride, polypropylene, polyethylene, polyurethane, acrylic foam, acrylic foam, polyethylene foam, and EVA foam, and the adhesive 52 includes one of acrylic adhesive and rubber-based adhesive.

[0040] Specifically, the adhesive assembly adopts a layered structure consisting of a substrate and adhesives located on both sides of the substrate. Release paper covers the outside of the adhesive. The release paper can isolate dust and moisture from contaminating the adhesive interface, which helps to ensure the performance consistency of the adhesive before construction, reduce the risk of local bonding failure caused by adhesive surface contamination, help maintain the morphological stability of the adhesive assembly during storage and transportation, and achieve rapid exposure of the adhesive interface by tearing off the release paper during construction.

[0041] Optionally, thin-film substrates such as polyester and polyvinyl chloride in the substrate can provide tensile support for the adhesive layer, which helps maintain the dimensional stability of the adhesive components during installation; foam substrates such as acrylic foam and EVA foam have compression resilience, which can adapt to the microscopic unevenness of the base wall surface in conjunction with the thickness of the adhesive components, thereby increasing the effective bonding area.

[0042] Optionally, an acrylic adhesive or a rubber-based adhesive can be used. Acrylic adhesives have better resistance to temperature changes and aging, while rubber-based adhesives usually have higher initial tack. The two can be selected according to the actual use environment and construction requirements to balance initial positioning ability and long-term bonding reliability.

[0043] Furthermore, the initial tack of the adhesive component is greater than 22N, the peel force is greater than 35N, and the adhesive component can withstand a load of 2kg per square inch at 40°C for more than 72 hours and a load of 3kg per square inch at 25°C for more than 48 hours.

[0044] Specifically, the initial tack of the adhesive components is greater than 22N, which helps the wall panel to obtain sufficient initial fixing force after being attached to the wall surface, reducing the risk of slippage or displacement caused by its own weight before the adhesive is fully cured, and facilitating position adjustment and fixation during construction.

[0045] Specifically, a peel force greater than 35N helps to enhance the bonding strength between the adhesive layer and the wall panel and wall surface, reduce the possibility of edge lifting or delamination caused by interface stress concentration, and improve the long-term reliability of the connection structure.

[0046] Specifically, the adhesive properties of the adhesive components, which can withstand a load of 2 kg per square inch at 40°C for more than 72 hours and a load of 3 kg per square inch at 25°C for more than 48 hours, help ensure the creep resistance of the adhesive under specific temperature and load conditions. This ensures that the adhesive layer does not undergo excessive plastic deformation or failure under high temperature environment or long-term self-weight load, adapting to different climatic conditions and long-term use requirements.

[0047] Furthermore, such as Figure 7As shown, the adhesive assembly 5 includes a first double-sided adhesive 54 and a first fastener 55 connected to the wall surface 100, a second double-sided adhesive 56 connected to the wall panel 1, and a second fastener 57 connected to the second double-sided adhesive 56.

[0048] Specifically, the adhesive assembly employs a structure where a first double-sided adhesive and a first fastener work together, and a second double-sided adhesive and a second fastener work together, creating a composite connection between the wall panel and the wall surface that combines chemical bonding and mechanical interlocking. The mushroom-shaped fastener achieves mechanical connection through the interlocking of its head structure. It features repeated opening and closing; when replacing a panel or inspecting the interior of the wall, the fastener can be separated by applying a peeling force, facilitating non-destructive disassembly of the wall panel and reducing the risk of damage to the wall panel and substrate during later maintenance. The double-sided adhesive and the mushroom-shaped fastener work synergistically. The double-sided adhesive provides continuous interfacial bonding to maintain airtightness and initial positioning, while the mushroom-shaped fastener provides mechanical anchoring to enhance shear and peel resistance. Together, they help disperse stress generated by external loads, reducing the possibility of overall loosening due to partial failure of a single connection method. Furthermore, the changes in mechanical resistance generated during the fastening process of the mushroom-shaped fastener provide installation feedback for the installer. Combined with the initial adhesion of the double-sided adhesive, this helps control the wall panel position during the pressing and bonding stage, reducing panel displacement caused by insufficient initial adhesion or operational errors.

[0049] The composite component, formed by combining double-sided tape and mushroom-shaped fasteners, has a certain thickness. This thickness can work together to absorb the microscopic flatness deviations of the base wall surface through the buffer space, and dissipate vibration energy through the elastic contact of the fastener structure.

[0050] Specifically, when using the mushroom-shaped hook and loop fastener to disassemble the wall panel, the fastener can be opened by sliding the first and second hook and loop fasteners together, and then the wall panel can be peeled off the wall. If necessary, the first hook and loop fastener or the first double-sided tape can be removed from the wall by pressing one end of the first hook and loop fastener or the first double-sided tape against the wall and slowly pulling the other end.

[0051] Specifically, the first and second fasteners are mechanical fasteners that can be repeatedly opened and closed. Optionally, the first and second fasteners are hook and loop fastener structures that cooperate with each other, or mushroom-shaped fasteners.

[0052] Compared to adhesive components with release paper pre-installed on the back of the wall panel, the separate first and second fasteners, first double-sided adhesive and second double-sided adhesive provided in this embodiment allow operators to easily arrange the adhesive components according to the site conditions.

[0053] like Figure 1 and Figure 2The wall panel installation structure shown has a thickness of 1.5-2.5mm for the raised locking strip 2, a height of 3.5-4.5mm for the raised locking strip 2, and an end with a bevel or arc surface.

[0054] like Figure 2 As shown, the thickness 'a' of the raised locking strip is set to 1.5-2.5mm, and the height 'b' is set to 3.5-4.5mm. This helps ensure sufficient cross-sectional strength of the locking strip, reducing the risk of bending deformation or breakage during installation or long-term use, thereby maintaining the mechanical stability of the locking structure. The beveled or curved surface structure at the end of the locking strip acts as a guide when splicing adjacent wall panels, helping to correct minor alignment deviations, reducing resistance when the locking strip is inserted into the locking groove, and reducing edge damage caused by hard impacts. Within this size range, the locking strip and locking groove, when mated, help form a tight joint interface, reducing gaps at the panel joints and positively impacting the sealing performance of the connection. Furthermore, the height design of the locking strip, in conjunction with the thickness of the adhesive components, ensures that the locking structure maintains an effective mating depth when the wall panel is adjusted to accommodate deviations in the flatness of the substrate, reducing the risk of locking failure due to wall surface undulations.

[0055] like Figure 1 and Figure 2 The wall panel installation structure shown includes a locking groove 3 with a locking groove opening 33 for the protruding locking bar 2 to extend into, a first extension 31 located on one side of the locking groove opening 33, and a second extension 32 located on the other side of the locking groove opening 33. The extension length of the first extension 31 is greater than the extension length of the second extension 32. The second extension 32 is provided with a guide surface 321. The protruding locking bar 2 extends into the locking groove 3 after abutting against the first extension 31 and / or the second extension 32.

[0056] Specifically, in the asymmetrical structure of the first and second extensions, the longer first extension, in the locked state, can form a larger overlapping mating area with the raised locking strip, which helps to distribute the load at the joint and reduce the risk of deformation caused by local stress concentration. The guide surface of the second extension can guide the raised locking strip into the locking groove during wall panel splicing. Combined with the limiting effect of the first extension, it helps to correct minor alignment deviations during installation and reduce the resistance of the locking operation. In addition, the mating method of the raised locking strip extending into the extension after contact allows the wall panel to be initially aligned at a certain angle before locking. This design is adaptable to installation operations in narrow spaces or edge areas. The length difference between the first and second extensions can also form a directional mating feature, which helps construction personnel identify the installation direction and reduces mating abnormalities caused by reverse installation.

[0057] Optionally, in some embodiments, the second extension 32 is close to the wall 100, and the protruding locking bar 2 first approaches the first extension 31 from bottom to top and moves upward along the first extension 31. With the alignment and cooperation of the second extension 32, the protruding locking bar 2 extends into the locking groove 3.

[0058] Optionally, in some embodiments, when the first extension 31 is close to the wall 100 and the protruding locking bar 2 is inclined to extend into the locking groove 3, the protruding locking bar 2 cooperates with the guide surface 321 and the protruding locking bar is adjusted to extend into the locking groove 3.

[0059] Optionally, in some embodiments, the first extension 31 is close to the wall 100. When the protruding locking bar 2 is inclined into the locking groove 3, the protruding locking bar 2 cooperates with the guide surface 321. The protruding locking bar 2 continues to be inclined into the first extension 31 and abuts against the first extension 31. The protruding locking bar is adjusted to extend into the locking groove 3.

[0060] like Figure 1 and Figure 2 The wall panel installation structure shown has a raised locking strip 2 with a first step 21 on one side and opposite to the first extension 31, and a second step 22 on the other side and abutting against the second extension 32. The wall panel 1 has a thickness of 3-8 mm, the second step 22 has a thickness of 1-2 mm, and a gap 4 is formed between the top of the first step 21 and the bottom of the first extension 31. The height of the gap 4 is between 0.5-1 mm.

[0061] like Figure 2 As shown, the abutment between the second step and the second extension helps to determine the relative position of the wall panel after installation. With a wall panel thickness of 3-8mm c, it can provide structural rigidity for the connection and reduce the risk of deformation under pressure.

[0062] Specifically, the wall panel is one of the following: rigid stone-plastic composite board (Rigid SPC board), plywood, MDF, or wood-plastic composite board (WPC board). Rigid SPC boards and WPC boards, among other composite materials, possess good dimensional stability, high strength, impact resistance, and waterproof sealing properties, reducing post-installation deformation caused by changes in moisture content and helping to maintain the fitting accuracy of the locking structure. Plywood and MDF are easy to cut on-site, and combined with the beveled or curved guide design at the end of the locking strip in this invention, the installation difficulty of irregularly shaped parts can be reduced.

[0063] like Figure 2 As shown, a gap e with a height of 0.5-1mm is provided between the top of the first step 21 and the bottom of the first extension 31. This gap provides displacement adjustment margin for the locking structure, which helps to absorb the flatness deviation of the base wall or the cumulative error of the board processing, and avoids the warping of the wall panel caused by rigid interference.

[0064] like Figure 2 As shown, the thickness d of the second step is set to 1-2 mm, which helps to ensure that the locking root has a sufficient shear-resistant section and reduces the risk of cracking caused by stress concentration. In addition, this gap size is coordinated with the buffer thickness of the adhesive component. When the adhesive layer undergoes compression deformation due to unevenness of the base layer, the gap inside the locking structure can accommodate the corresponding displacement adjustment, reduce structural stress resistance, and improve installation adaptability.

[0065] like Figure 3 and Figure 4 As shown, the first extension 31 is provided with a first extension engagement end 311, and the protruding locking strip 2 is provided with a protruding locking strip engagement end 23 that cooperates with the first extension engagement end 311. By cooperating with the first extension engagement end 311 and the protruding locking strip engagement end 23, the connection stability between adjacent wall panels 1 is improved.

[0066] Furthermore, an installation method for a wall panel mounting structure, applied to the wall panel mounting structure described above, includes the following steps: S1. Clean the wall surface 100 and attach the adhesive component 5 to the wall surface and / or wall panel 1; S2. After peeling off all the release paper 53, attach the wall panel 1 to the wall surface 100 and press it to make the adhesive components contact the wall surface 100. S3. Adjacent wall panels 1 are interlocked through a locking structure to achieve splicing and overall leveling.

[0067] Specifically, this installation method simplifies the on-site construction process by using pre-installed adhesive components and locking structures, reducing it to steps such as wall cleaning, pre-installation of adhesive components, pressing and bonding after removing the release paper, and locking adjacent wall panels. The pre-fabricated adhesive components reduce the need for on-site adhesive mixing and application, helping to minimize fluctuations in adhesive quality due to variations in manual operation and improving the consistency of bonding results under different construction conditions. The initial tack provided by the adhesive components after removing the release paper allows the wall panels to achieve initial positioning after pressing and bonding, reducing the need for temporary fixing measures. Combined with the mechanical cooperation of the subsequent locking steps, this helps to shorten the installation time for a single wall panel.

[0068] Specifically, during the pressing process, the adhesive components with a specific thickness can undergo adaptive deformation, providing initial compensation for local flatness deviations of the base wall surface. Subsequently, through the cooperation of the interlocking structure of adjacent wall panels, the relative positions of multiple wall panels can be constrained, making the panels tend to be coplanar during the splicing process. This synergistic effect has a positive effect on improving the surface flatness after large-area paving.

[0069] Furthermore, this method primarily utilizes dry or semi-dry operations, reducing adhesive contamination and solvent evaporation from on-site wet work, thus improving the construction environment and reducing the difficulty of protecting finished products and subsequent cleaning. When partial replacement of individual panels is required, disassembly can be achieved by releasing the locking connections and peeling off the adhesive components. This method carries a low risk of damage to the wall panel itself and the substrate, and offers a degree of maintainability.

[0070] Example 1 like Figure 1 , Figure 2 , Figure 5 and Figure 6 The wall panel installation structure shown includes two or more wall panels 1. Each wall panel 1 has a locking structure and an adhesive assembly 5 on its back. The locking structure includes a raised locking strip 2 and a locking groove 3 that mates with the raised locking strip 2. The adhesive assembly 5 has a substrate 51, adhesive 52 on both sides of the substrate 51, and release paper 53 covering the outside of the adhesive 52. Adjacent wall panels 1 are locked together by the raised locking strip 2 and the locking groove 3. After the release paper is removed, the adhesive assembly 5 is used to adhere the wall panel 1 to the wall surface 100. The wall panel 1 is a rigid stone-plastic composite panel.

[0071] The wall panel 1 has locking structures on all four sides, and the adhesive components 5 are provided in four sets, spaced apart and arranged in parallel. The adhesive components 5 are arranged vertically.

[0073] The substrate 51 is acrylic foam, and the adhesive 52 is acrylic glue.

[0074] The adhesive component has an initial tack greater than 22N and a peel force greater than 35N. The adhesive component can withstand a load of 2kg per square inch for more than 72 hours at 40°C and a load of 3kg per square inch for more than 48 hours at 25°C.

[0075] The thickness a of the raised locking bar 2 is 2.0 mm, the height b of the raised locking bar 2 is 4.0 mm, and the end of the raised locking bar 2 is provided with an arc surface.

[0076] The lock groove 3 includes a lock groove opening 33 into which the protruding lock bar 2 extends, a first extension 31 located on one side of the lock groove opening 33, and a second extension 32 located on the other side of the lock groove opening 33. The extension length of the first extension 31 is greater than the extension length of the second extension 32. The second extension 32 is provided with a guide surface 321. After the protruding lock bar 2 abuts against the first extension 31 and the second extension 32, it extends into the lock groove 3.

[0077] The raised locking bar 2 has a first step 21 on one side and opposite to the first extension 31, and a second step 22 on the other side and abutting against the second extension 32. The wall panel 1 has a thickness c of 5.1 mm, the second step 22 has a thickness of 1.5 mm, and a gap 4 is formed between the top of the first step 21 and the bottom of the first extension 31. The height of the gap 4 is 0.7 mm.

[0078] An installation method for a wall panel mounting structure, applied to the wall panel mounting structure described above, includes the following steps: S1. Clean the wall surface 100, peel off the release paper 53 on one side of the adhesive component 5, and attach the adhesive component 5 to the wall panel 1. S2. After peeling off all the release paper 53, attach the wall panel 1 to the wall surface 100 and press for 30 seconds to make the adhesive component 5 contact the wall surface 100. S3. Adjacent wall panels 1 are interlocked through a locking structure to achieve splicing and overall leveling.

[0079] Example 2 Example 2, based on Example 1, also has the following implementation method: like Figure 7 As shown, the adhesive assembly 5 includes a first double-sided adhesive 54 and a first fastener 55 connected to the wall surface 100, a second double-sided adhesive 56 connected to the wall panel 1, and a second fastener 57 connected to the second double-sided adhesive 56. The adhesive assembly 5 is arranged vertically. The first fastener 54 and the second fastener 57 are mushroom-shaped fasteners that cooperate with each other. The adhesive assembly 5 includes a double-sided adhesive tape structure.

[0080] An installation method for a wall panel mounting structure, applied to the wall panel mounting structure described above, includes the following steps: S1. Clean the wall surface 100, attach the first double-sided adhesive 54 to the wall surface 100, attach the first fastener 55 to the surface of the first double-sided adhesive 54, attach the second fastener 57 to the first fastener 55, and attach one side of the second double-sided adhesive 56 to the wall panel 1; press for 30 seconds to bring the first double-sided adhesive 54 into contact with the wall surface 100.

[0091] Comparative Example 1 The difference between Comparative Example 1 and Example 1 is that wall panel 1 is a regular flat plate, and adjacent wall panels are spliced ​​together by sealing and bonding with adhesive 52.

[0092] This invention provides a wall panel structure and installation method to solve the problems of complex installation procedures, reliance on wall flatness, lack of cushioning capacity, and insufficient waterproof sealing of traditional wall panels.

It can withstand high temperatures of 70°C for 5-8 hours and undergoes a load-bearing test in a humid environment at 40°C and 90% relative humidity, remaining stable for 30 days. The individual wall panel dimensions are 150mm in length, 60mm in width, and 5.1mm in thickness (c). The adhesive component 5 includes a double-sided adhesive tape structure; for each wall panel, two sets of double-sided adhesive tape are symmetrically arranged along the central axis of the wall panel.

[0093] In Example 1: Each set of double-sided tape measures 54*16mm, and a pair of double-sided tapes can support a weight of 0.63kg.

[0094] Each set of double-sided tape measures 94*12mm, and a pair of double-sided tapes can support a weight of 1.4kg.

[0098] In Example 2: Each set of double-sided tape measures 54*16mm, and a pair of double-sided tapes can support a weight of 0.68kg.

[0099] Each set of double-sided tape measures 94*12mm, and a pair of double-sided tapes can support a weight of 1.48kg.

[0100] Each set of double-sided tape measures 70*19mm, and a pair of double-sided tapes can support a weight of 1.45kg.

[0106] Each set of double-sided tape measures 94*19mm, and a pair of double-sided tapes can support a weight of 1.51kg.

[0107] Each set of double-sided tape measures 112*22mm, and a pair of double-sided tapes can support a weight of 1.83kg.

[0108] Specifically, this invention refers to GB / T 4852-2002 for initial tack test; refers to GB / T 2792-2014 for peel force test; and refers to GB / T 4851-2014 for holding performance test at 40°C with a load of 2 kg per square inch for a time and at 25°C with a load of 3 kg per square inch for a time.

[0109] Table 1. Performance tests of Examples 1 to 6 and Comparative Example 1

[0110] As shown in Table 1, the rubber-type adhesive used in Example 6 exhibits a significant advantage in initial tack at the same thickness, making it suitable for scenarios requiring rapid positioning. The acrylic adhesives used in the other examples demonstrate superior temperature resistance and tack, making them suitable for long-term load-bearing requirements. In Example 5, the substrate has a slightly lower elastic modulus, and with a reduced overall thickness, the peel force and tack performance are slightly lower than in Example 1.

[0111] The comparison of load-bearing capacity between Example 2 and Example 1, as well as the superior peel strength and adhesion of Examples 2 to 4 compared to Example 1, indicate that the composite connection of adhesive and mechanical interlocking can improve interface reliability.

[0112] Comparative Example 1 data shows that, compared to the load-bearing capacity of Example 1, when relying solely on adhesive bonding without the cooperation of the protruding locking strip and locking groove to reduce moisture penetration, the peel force and holding power are significantly reduced.

[0113] The optimized installation process in Example 3 results in a more thorough adhesion of the adhesive interface, leading to slightly better performance than Example 2. Example 4, through optimized installation sequence, improves construction convenience and also slightly outperforms Example 2. Example 3 addresses the technical challenge of not being able to directly apply pressure to the adhesive layer on the wall surface when large wall panels are obstructing the view, thus ensuring sufficient wetting of the double-sided adhesive to the wall substrate. Therefore, Example 3's performance is slightly superior to Example 4.

[0114] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples. Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
