[0036] This application provides a wall panel mounting structure. To enable those skilled in the art to better understand the technical solution of this application, the following description is provided in conjunction with the appendix. Figure 1-8 The technical solutions of this application will be further described in detail below with reference to specific embodiments.

[0037] like Figure 1 As shown, the wall panel installation structure provided in this application includes a wall panel 100, an upper connecting component 200, and a fixing component 300.

[0038] The wall panel 100 includes a decorative panel 101, and an upper connecting component 200 is fixed to the back side of the upper edge of the decorative panel 101 (i.e., the side of the decorative panel 101 facing the wall 1000). The upper connecting component 200 is provided with a connecting hole A. The wall 1000 is provided with a fixing hole B that aligns with the connecting hole A on the upper connecting component 200.

[0039] The fixing component 300 includes a mesh sleeve 301, expansion bolts 302, and adhesive 303 filled in the mesh sleeve 301. The mesh sleeve 301 is installed in the fixing hole B, and the length of the mesh sleeve 301 is greater than the length of the fixing hole B. When the mesh sleeve 301 is installed in the fixing hole B, the end of the mesh sleeve 301 away from the decorative panel 101 is located outside the fixing hole B. The expansion bolts 302 are sequentially inserted into the connecting hole A and the mesh sleeve 301 filled with adhesive 303. When the expansion bolts 302 expand, the mesh sleeve 301 deforms along with them. After the expansion bolts 302 expand, at least part of the mesh sleeve 301 and at least part of the adhesive 303 will be covered on the expansion head, thereby forming the anchoring part C. The bolt head of the expansion bolt 302 and the anchoring part C cooperate to fix the upper connecting component 200 to the wall 1000. After fixing, part of the upper connecting component 200 and part of the wall 1000 are anchored between the bolt head of the expansion bolt 302 and the anchoring part C.

[0040] When installing the decorative panel 101, first, a fixing hole B is opened on the wall 1000, then a mesh sleeve 301 is installed in the fixing hole B, and then adhesive 303 is filled into the mesh sleeve 301. Then, the expansion bolt 302 is inserted into the connecting hole A of the upper connecting component 200 and into the mesh sleeve 301 filled with adhesive 303. In this way, after the expansion bolt 302 expands, the expansion head will be covered with at least part of the mesh sleeve 301 and at least part of the adhesive 303, thus forming an anchoring part C with a large cross-sectional area.

[0041] The above-described installation structure utilizes the bolt heads of expansion bolts 302 and the expansion heads covered with mesh sleeves 301 and adhesive 303 to secure the upper connecting component 200 to the wall 1000. This ensures the installation firmness of the wall panel 100 on the hollow brick wall, thereby solving the problems of insufficient tensile strength and poor wind resistance faced when the wall panel 100 is installed on the hollow brick wall 1000. Of course, this installation structure can also be used on solid brick walls.

[0042] Specifically, Figure 1 In this design, the wall panel 100 also includes an insulation layer 102, which is adhered to the back side of the decorative panel 101. Expanding foam 900 is filled between the insulation layer 102 and the wall 1000. The insulation layer 102, decorative panel 101, and upper connecting component 200 can be prefabricated together in the factory. This way, on-site installation only requires filling the space between the insulation layer 102 and the wall 1000 with expanding foam 900 and fixing the upper connecting component 200 to the wall 1000. Alternatively, the decorative panel 101 and upper connecting component 200 can be prefabricated together in the factory, and the bonding of the insulation layer 102 and the decorative panel 101 can be performed on-site.

[0043] Specifically, Figure 1 In the middle, the upper connecting assembly 200 includes a connecting plate 201 and a wall connecting member 202. Both the connecting plate 201 and the wall connecting member 202 are approximately "L"-shaped. The vertical part of the connecting plate 201 is bonded to the back side of the decorative panel 101. The back side of the decorative panel 101 has a groove, and the vertical part of the connecting plate 201 has a protrusion that inserts into the groove, thereby enhancing the connection strength between the decorative panel 101 and the connecting plate 201. The horizontal part of the wall connecting member 202 is connected to the horizontal part of the connecting plate 201 by screws. The holes on the wall connecting member 202 and / or the connecting plate 201 for passing screws are elongated holes, so that the wall connecting member 202 can be appropriately adjusted inward and outward and / or left and right relative to the connecting plate 201. Figure 1 (The direction perpendicular to the paper is the left-right direction). The vertical part of the wall connector 202 abuts against the wall 1000, and the connecting hole A is set on the vertical part of the wall connector 202. In actual implementation, the structure of the upper connecting component 200 is not limited to this, as long as it can be reliably connected to the back side of the decorative panel 101 and fixed to the wall 1000.

[0044] Specifically, Figure 1In this design, the expansion bolt 302 is an umbrella-shaped expansion bolt, meaning that the cross-sectional area of ​​the expanded head gradually increases towards the bolt head after expansion. Using an umbrella-shaped expansion bolt 302 ensures a larger contact area between the formed anchoring part C and the wall 1000, thus improving the connection strength between the upper connecting component 200 and the wall 1000. Of course, other types of expansion bolts can also be selected.

[0045] Specifically, Figure 1 In this design, the mesh sleeve 301 is a metal mesh sleeve. The high strength of the metal mesh sleeve ensures a strong anchoring point C, thus enhancing the connection strength between the upper connecting component 200 and the wall 1000. Of course, other materials for the mesh sleeve 301 can also be chosen, such as plastic or nylon mesh sleeves.

[0046] Specifically, the joints between the decorative panels 101 were sealed by first filling the joints with foam 1100 and then filling the joints with sealant 1200.

[0047] In some embodiments, such as Figure 2 and Figure 3 As shown, a lower insert 500 is fixed to the back side of the lower edge of the decorative panel 101. An upper slot D is formed between the upper connecting component 200 and the back side of the decorative panel 101. The upper slot D is used to insert the lower insert 500 connected to the back side of the lower edge of the upper decorative panel 101. The portion of the lower insert 500 inserted into the upper slot D is bonded to the back side of the decorative panel 101 and the upper connecting component 200. Alternatively, a lower slot can be formed between the lower insert 500 and the back side of the decorative panel 101. The lower slot is used to insert the upper connecting component 200 connected to the back side of the upper edge of the lower decorative panel 101. The portion of the upper connecting component 200 inserted into the lower slot is bonded to the back side of the decorative panel 101 and the lower insert 500.

[0048] During installation, the lower insert 500 connected to the back side of the lower edge of the upper decorative panel 101 is inserted into the upper slot D on the back side of the adjacent lower decorative panel 101, and the portion of the lower insert 500 inserted into the upper slot D is bonded to the back side of the decorative panel 101 and the upper connecting assembly 200. Alternatively, the upper connecting assembly 200 connected to the back side of the upper edge of the lower decorative panel 101 is inserted into the lower slot on the back side of the adjacent upper decorative panel 101, and the portion of the upper connecting assembly 200 inserted into the lower slot is bonded to the back side of the decorative panel 101 and the lower insert 500.

[0049] Specifically, Figure 2In the middle, the upper connecting assembly 200 includes a connecting plate 201, a wall connecting member 202, and a wall embedded member 203. The wall embedded member 203 is connected to the wall connecting member 202 via a threaded connector. The connecting plate 201, the wall connecting member 202, and the wall embedded member 203 can be finely adjusted in relative positions in the up-down, left-right, and in-outward directions through elongated holes, so that the connecting hole A can be adjusted to be precisely aligned with the fixing hole B on the wall 1000.

[0050] like Figure 4 As shown, two adjacent decorative panels 101 can be installed flush, meaning the seam of the upper decorative panel 101 and the seam of the adjacent lower decorative panel 101 are aligned vertically. When the two adjacent decorative panels 101 are installed flush, the lower insert 500 connected to the upper decorative panel 101 can be inserted into the upper slot D on the back of the lower decorative panel 101, thereby bonding it to the back of the decorative panel 101 and the upper connecting component 200. Alternatively, the upper connecting component 200 connected to the lower decorative panel 101 can be inserted into the lower slot on the back of the upper decorative panel 101, thereby bonding it to the back of the decorative panel 101 and the lower insert 500. Therefore, a reliable connection between the two adjacent decorative panels 101 can be achieved.

[0051] like Figure 5 As shown, two adjacent decorative panels 101 can be installed with staggered joints, meaning the joints of the upper decorative panel 101 and the adjacent lower decorative panel 101 are staggered in the left-right direction. When two adjacent decorative panels 101 are installed with staggered joints, the lower insert 500 connected to the upper decorative panel 101 may be misaligned with the upper slot D on the back of the lower decorative panel 101 in the left-right direction. This prevents the lower insert 500 connected to the upper decorative panel 101 from being inserted into the upper slot D on the back of the lower decorative panel 101, thus preventing it from bonding with the upper connecting component 200 connected to the lower decorative panel 101. Similarly, it may also prevent the upper connecting component 200 connected to the lower decorative panel 101 from bonding with the upper decorative panel 101. The lower slots on the back of 101 are staggered in the left-right direction, which prevents the upper connecting component 200 connected to the lower decorative panel 101 from being inserted into the lower slot on the back of the upper decorative panel 101, thus preventing it from being bonded to the lower plug 500 connected to the upper decorative panel 101. Therefore, when two adjacent decorative panels 101 are installed with staggered joints, the lower plug 500 may not be able to be inserted into the upper slot D or the upper connecting component 200 may not be able to be inserted into the lower slot, making it impossible to achieve a reliable connection between the two adjacent decorative panels 101.

[0052] To ensure a reliable connection between adjacent decorative panels 101 during staggered installation, such as Figure 1As shown, when installing the upper decorative panel 101, the clamping assembly 400 is first installed at the upper edge of the lower decorative panel 101. The clamping assembly 400 includes an inner clamping plate 401, an outer clamping plate 402, and screws 403. The screws 403 connect the inner clamping plate 401 and the outer clamping plate 402 together. Structural adhesive 404 is provided on the outer side of the inner clamping plate 401. After installation, the inner clamping plate 401 is bonded to the back side of the upper edge of the lower decorative panel 101, and the outer clamping plate 402 is located on the front side of the upper edge of the lower decorative panel 101. The screws 403 are supported on the upper side of the lower decorative panel 101. A gap is formed between the inner clamping plate 401 and the outer clamping plate 402, and the gap is located above the lower decorative panel 101. Then, insert the upper decorative panel 101 into the slot between the inner clamping plate 401 and the outer clamping plate 402, and then tighten the screws 403 of the clamping plate assembly 400 so that the inner clamping plate 401 and the outer clamping plate 402 clamp the upper decorative panel 101. Then, after the structural adhesive 404 has cured, remove the outer clamping plate 402 and the screws 403. After installation, as shown... Figure 1 and Figure 6 As shown, the inner panel 401 is bonded to the back side of the lower edge of the upper decorative panel 101 and the back side of the upper edge of the adjacent lower decorative panel 101, thereby achieving a reliable connection between the two adjacent decorative panels 101.

[0053] Specifically, the two adjacent decorative panels 101 can be reliably connected entirely by bonding with the inner panel 401 (e.g., Figure 6 As shown), that is, the lower edge of the decorative panel 101 may not have the aforementioned lower insert 500 on its back side. Alternatively, two adjacent decorative panels 101 can also achieve a reliable connection by simultaneously bonding with the inner clamping plate 401 and bonding the lower insert 500 with the upper connecting assembly 200 (as shown). Figure 7 As shown), that is, the lower edge of the decorative panel 101 can be provided with the aforementioned lower insert 500, and the upper edge of the decorative panel 101 can also be provided with the aforementioned inner clamping plate 401.

[0054] Specifically, such as Figure 6 As shown, some inner panels 401 are long panels, which span the joint of two adjacent decorative panels 101 on the same layer and are bonded to the back side of the upper edge of the two decorative panels 101.

[0055] In some embodiments, such as Figure 8As shown, the wall panel mounting structure includes a replacement decorative panel 600, a replacement insert 700, and a wall mounting assembly 800. At least one replacement insert 700 is fixed to the back side of the left and right edges of the replacement decorative panel 600. At least one set of wall mounting assemblies 800 is provided on the back side of the decorative panels 101 on both the left and right sides of the replacement decorative panel 600. The wall mounting assemblies 800 are fixed to the wall 1000 and form slots with the back of the decorative panels 101. The replacement decorative panels 600 connected to the back sides of the left and right edges of the replacement decorative panel 600 are respectively inserted into the slots on the same side and fixed to the wall mounting assemblies 800 on the same side by threaded fasteners 1300. The threaded fasteners 1300 are inserted from the joint between the replacement decorative panel 600 and the decorative panel 101.

[0056] When a decorative panel 101 of the wall panel 100 is damaged, the damaged decorative panel 101 can be replaced with a replacement decorative panel 600. The replacement includes the following steps: First, at least one set of wall-mounting components 800 is installed on the back side of the decorative panel 101 on the left and right sides of the position to be replaced, and the wall-mounting components 800 are fixed to the wall 1000, so that the left wall-mounting component 800 and the back side of the decorative panel 101 form a left slot, and the right wall-mounting component 800 and the back side of the decorative panel 101 form a right slot; then, the replacement plugs 700 connected to the back side of the left edge and the back side of the right edge of the replacement decorative panel 600 are inserted into the left slot and the right slot, respectively; then, threaded fasteners 1300 are inserted into the joint between the replacement decorative panel 600 and the decorative panels 101 on the left and right sides, and the threaded fasteners 1300 fix the replacement plugs 700 connected to the back side of the left edge and the back side of the right edge of the replacement decorative panel 600 to the wall-mounting components 800 on the left and right sides, respectively.

[0057] Specifically, Figure 8 In the wall mounting assembly 800, there are a first connector 801 and a second connector 802. Both the first connector 801 and the second connector 802 are approximately "L"-shaped. The first connector 801 is fixedly connected to the replacement plug-in 700 by a threaded fastener 1300, and the first connector 801 is fixedly connected to the second connector 802 by screws. The second connector 802 is fixed to the wall 1000 by expansion bolts. Alternatively, the second connector 802 can also be fixed to the wall 1000 by the aforementioned fixing assembly 300.

[0058] The above embodiments can be freely combined without conflict.

[0059] The above examples illustrate the principles and implementation methods of this application. The descriptions of the embodiments are merely for the purpose of helping to understand the methods and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
