Description

Technical Field

[0001] This utility model belongs to the field of building decoration technology, specifically relating to a prefabricated wall panel connection device. Background Technology

[0002] Prefabricated wall decoration typically involves attaching large decorative wall panels to the building's structural walls using structural adhesives or hooks. Compared to the traditional method of "applying cement mortar to the structural walls and then tiling or painting," prefabricated decoration offers the advantage of faster construction. It also significantly reduces manual labor involved in tasks such as plastering cement mortar, tiling, and painting; therefore, prefabricated decoration is becoming increasingly popular. Currently, decorative wall panels are mostly installed onto the wall using "integrated connectors" (such as "I"-shaped or "T"-shaped integrated connectors). The installation has a specific sequence requirement. For example, if the decorative wall panels are installed from right to left, assuming the first decorative wall panel on the right has already been installed, the "I"-shaped integrated connector needs to be inserted into the left side of the first decorative wall panel. Then, screws are used to fix the "I"-shaped integrated connector to the horizontal joist. Next, the second decorative wall panel is inserted into the left slot of the "I"-shaped integrated connector, following the sequence: "Decorative wall panel → integrated connector". The installation process is repeated in the order of "→decorative wall panel→integrated connector...". If a decorative wall panel is skipped in the middle, it will be impossible to install the next decorative wall panel in that position because it will be blocked by the limiting part of the integrated connector. This method is inflexible in terms of installation. At the same time, this assembly method also has the problem of inconvenient maintenance. For example, if a wall has ten decorative wall panels, and the fifth decorative wall panel from the right is damaged and needs to be replaced, the installation order must be reversed from left to right. The five decorative wall panels on the left must be removed first, and only then can the decorative wall panel that needs to be replaced be removed.

[0003] Currently, there is a need to develop a new type of prefabricated wall panel connection device to reduce the difficulty of wall panel installation and disassembly, and to facilitate wall panel maintenance. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a prefabricated wall panel connection device, which can reduce the difficulty of wall panel installation and disassembly, and facilitate wall panel maintenance.

[0005] The present invention adopts the following technical solution: A prefabricated wall panel connection device includes a connecting assembly and a second limiting member. The connecting assembly includes a connecting seat and a first limiting member. The connecting seat is directly or indirectly connected to a wall. The connecting seat has a first limiting groove for connecting to one side of the wall panel. The connecting seat also has a second limiting groove for connecting to the first limiting member. The second limiting member is disposed on the connecting seat, or the second limiting member is detachably disposed on a set structure and located below the connecting seat. The second limiting member is used to prevent the first limiting member from falling out of the second limiting groove. The first limiting member is detachably connected in the second limiting groove to limit the wall panel.

[0012] Furthermore, a prefabricated wall panel connection device further includes a magnetic connector; the magnetic connector is disposed on the wall panel; the wall panel is attracted and fixed to the set vertical keel by the magnetic connector, and the wall panel is connected to the connecting seat at a set position.

[0013] Furthermore, a prefabricated wall panel connection device also includes a joint sealant strip; the joint sealant strip is used to be disposed between two adjacent wall panels.

[0014] Further, the connecting seat includes a first L-shaped plate, a second L-shaped plate, a third L-shaped plate, and a fourth L-shaped plate; the first L-shaped plate is connected to the fourth L-shaped plate; the second L-shaped plate is connected to the first L-shaped plate and forms the first limiting groove; the third L-shaped plate is connected to the fourth L-shaped plate and forms the second limiting groove; the third L-shaped plate is adjacent to the first L-shaped plate, and a gap is formed between the third L-shaped plate and the first L-shaped plate for the first limiting member to be installed, the gap communicating with the second limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a prefabricated wall panel connection device, comprising a connecting component and a second limiting member.

The existence of this connecting component and the second limiting member reduces the difficulty of installing and disassembling the wall panel and facilitates the maintenance of the wall panel.

Preferably, the first fastener 421 is a wood screw.

[0026] Reference Figures 1 to 14 In one embodiment, the connecting body 41 is a tubular body with an open cross-section, wherein an open cross-section means that the front cross-section of the tubular body is open; the length of the connecting body 41 is less than the length of the vertical keel 3. Preferably, the front cross-section of the tubular body is a square cross-section, and the square cross-section has an opening.

[0027] Reference Figures 1 to 14 In one embodiment, the vertical keel 3 is a tubular keel with an open cross-section, where an open cross-section means that the front cross-section of the tubular keel is open. Preferably, the vertical keel 3 is fitted onto the outer side of the connecting body 41 and locked to the connecting body 41 by a second fastener 43. Preferably, the second fastener 43 is a screw.

[0028] Reference Figures 1 to 14 In one embodiment, the length of the connector 41 is less than the length of the vertical keel 3; a single vertical keel 3 can be vertically connected to multiple connectors 41; this utility model chooses to vertically arrange multiple connectors 41 to connect to a single vertical keel 3, instead of designing the connector 41 as a component of the same length as the vertical keel 3. This design is beneficial for saving component materials and reducing decoration costs.

[0029] Preferably, the vertical keel 3 serves as the leveling keel for the wall panel 2, which helps the wall panel 2 to be neatly fixed to the wall 9.

[0030] Reference Figures 1 to 14In one embodiment, a prefabricated wall panel connection device further includes a bottom component 5, which is used to be disposed at the bottom position of the vertical keel 3; the bottom component 5 includes a base 51; the base 51 is connected to the vertical keel 3; the base 51 is provided with a third limiting groove 511 for connecting with the bottom of the wall panel 2.

[0031] Reference Figures 1 to 14 In one embodiment, the base 51 is connected to the vertical keel 3 by a third fastener 53. Preferably, the third fastener 53 is a screw.

[0032] Reference Figures 1 to 14 In one embodiment, the base 51 has a set length (e.g., a bottom crossbeam), the base 51 is arranged laterally at the bottom of the vertical keel 3, and the base 51 is connected to several of the vertical keels 3; after the base 51 is set, the length direction of the base 51 is consistent with the lateral direction of the wall 9, and the base 51 is fixed to the vertical outer surface of the vertical keel 3 (the surface away from the wall 91), which is beneficial to providing space for vertical pipelines X to pass through vertically (which helps to avoid structural and pipeline conflicts).

[0033] Reference Figures 1 to 14 In one embodiment, the bottom component 5 further includes a first cover 52, which is snap-fitted to the base 51 for easy installation and removal. After the first cover 52 is connected to the base 51, it conceals the third fastener 53 within the base 51 to ensure the aesthetic appearance of the decorative structure.

[0034] Reference Figures 1 to 14 In one embodiment, a prefabricated wall panel connection device further includes a top component 6, which is used to be disposed at the top of the vertical keel 3; the top component 6 includes a top seat 61, which is connected to the vertical keel 3; the top of the wall panel 2 is connected to the top seat 61.

[0035] Reference Figures 1 to 14 In one embodiment, the top seat 61 is connected to the vertical keel 3 by a fourth fastener 63; preferably, the fourth fastener 63 is a screw.

[0036] Reference Figures 1 to 14In one embodiment, the top seat 61 has a set length (e.g., a top beam), and the top seat 61 is arranged horizontally on the top of the vertical keel 3. The top seat 61 is connected to several of the vertical keels 3. After the top seat 61 is set, the length direction of the top seat 61 is consistent with the horizontal direction of the wall 9. The top seat 61 is fixed to the vertical outer surface of the vertical keel 3 (the surface away from the wall 91), which is beneficial for providing space for vertical pipelines X to pass through vertically (which helps to avoid structural and pipeline conflicts).

[0037] Reference Figures 1 to 14 In one embodiment, the top component 6 further includes a second cover 62, which is snap-fitted to the top seat 61 for easy installation and removal. After the second cover 62 is connected to the top seat 61, the second cover 62 conceals the fourth fastener 63 within the top seat 61 to ensure the aesthetic appearance of the decorative structure.

[0038] Reference Figures 1 to 14 Preferably, after the wall panel 2 is fixed on the vertical keel 3, the top back of the wall panel 2 is in contact with the top seat 61; after the second cover 62 is connected to the top seat 61, the second cover 62 is in contact with the top surface of the wall panel 2.

[0039] Reference Figures 1 to 14 In one embodiment, the connecting seat 11 is provided with a second connecting hole E, and the connecting seat 11 is fixed to a set structure (such as a vertical keel 3) through the second connecting hole E. Preferably, an assembled wall panel connecting device further includes a fifth fastener 13, which passes through the second connecting hole E to fix the connecting seat 11 to the vertical keel 3; preferably, the fifth fastener 13 is a screw.

[0040] Reference Figures 1 to 14 In one embodiment, the connecting seat 11 includes a first L-shaped plate 111, a second L-shaped plate 112, a third L-shaped plate 113, and a fourth L-shaped plate 114; the first L-shaped plate 111 is connected to the fourth L-shaped plate 114; the second L-shaped plate 112 is connected to the first L-shaped plate 111 and forms the first limiting groove B; the third L-shaped plate 113 is connected to the fourth L-shaped plate 114 and forms the second limiting groove C; the third L-shaped plate 113 is adjacent to the first L-shaped plate 111, and a gap F is formed between the third L-shaped plate 113 and the first L-shaped plate 111 for the first limiting member 12 to be installed, the gap F communicating with the second limiting groove C; the fourth L-shaped plate 114 is provided with a plurality of second connecting holes E.

[0041] One side of the wall panel 2 can be limited and connected to the first L-shaped plate 111. At that time, the first L-shaped plate 111 is inserted and connected to the connecting groove 21, and a part of the wall panel 2 is inserted into the first limiting groove B.

[0042] Reference Figure 2 In the first embodiment of the second limiting member D, the second limiting member D is disposed on the first L-shaped plate 111. The second limiting member D is a protrusion on the first L-shaped plate 111, which is used to restrict the first limiting member 12 from falling out of the second limiting groove C (such as falling down).

[0043] Reference Figure 1 In a second embodiment of the second limiting member D, the second limiting member D is a magnetic limiting block. After the first limiting member 12 is connected to the second limiting groove C at a set position, the magnetic limiting block is attracted to the vertical steel keel 3, and the magnetic limiting block is positioned below the second limiting groove C of the connecting seat 11. The magnetic limiting block is used to prevent the first limiting member 12 from falling out of the second limiting groove C. Specifically, after the wall panels are installed, there is a gap between the wall panels. At that time, the magnetic limiting block is attracted to the vertical steel keel 3 through this gap, and the magnetic limiting block is positioned below the second limiting groove C of the connecting seat 11, so that the magnetic limiting block abuts against the first limiting member 12 in the second limiting groove C, thereby preventing the first limiting member 12 from falling out of the second limiting groove C. The "setting structure" mentioned above, which is the vertical keel 3 made of steel, refers to the "setting structure" that is detachably mounted on the setting structure and located below the connecting seat 11.

[0044] In a third embodiment of the second limiting member, the second limiting member is one of a pin, a limiting block, or a screw. The vertical keel 3 has a third connecting hole for connecting with the second limiting member. After the first limiting member 12 is installed into the designated second limiting groove C, the second limiting member is then connected to the third connecting hole, placing the second limiting member below the second limiting groove C of the connecting seat 11 to prevent the first limiting member 12 from falling out of the second limiting groove C. Similarly, the second limiting member can be installed using the gap between wall panels, where it connects to the third connecting hole at the gap. If the second limiting member is a pin, the third connecting hole is a round hole, and the second limiting member can be inserted into the third connecting hole; if the second limiting member is a limiting block, the third connecting hole is a square hole, and the second limiting member can be inserted into the third connecting hole; if the second limiting member is a screw, the third connecting hole is a threaded hole, and the second limiting member can be rotated into the third connecting hole.

[0045] Reference Figures 1 to 14In one embodiment, the first limiting member 12 is a limiting member with a "U" shaped cross-section; the first limiting member 12 limits and connects one side of the wall panel 2 to the third L-shaped plate 113.

[0046] Reference Figure 5 , Figure 6 and Figure 7 Preferably, a connecting plate 14 is connected to the first limiting member 12. The connection between the connecting plate 14 and the first limiting member 12 is a weak part G, which has a groove G1, such that the thickness of the weak part G is less than the thickness H of the connecting plate 14. Through the connecting plate 14, the first limiting member 12 can be inserted into a set position in the connecting groove 21 of the wall panel 2, and the first limiting member 12 can be moved down to connect with the second limiting groove C of the connecting seat 11. When the first limiting member 12 connects one side of the wall panel 2 to the third L-shaped plate 111 of the connecting seat 11, the connecting plate 14 can be broken through the weak part G, thereby hiding the first limiting member 12 between two adjacent wall panels 2. At that time, if the wall panel 2 needs to be disassembled, the first limiting member 12 can be picked out from the bottom to the top of the second limiting groove C along the connecting groove 21 using some existing tools (such as screwdrivers), thereby releasing the limiting connection of the first limiting member 12 and finally removing the wall panel 2.

[0047] Reference Figures 1 to 14 In one embodiment, a prefabricated wall panel connection device further includes a magnetic connector 7; the magnetic connector 7 is disposed on the wall panel 2; the wall panel 2 is attracted and fixed to the set vertical keel 3 by the magnetic connector 7, and the wall panel 2 is connected to the connecting seat 11 at a set position.

[0048] Reference Figures 11 to 13 In one embodiment, the magnetic connector 7 is a square magnet block.

[0049] Reference Figure 7 In one embodiment, the magnetic connector 7 is fixed to the back of the wall panel 2 by structural adhesive Y, and the wall panel 2 is adsorbed and fixed to a set vertical keel 3 (such as adsorbed and fixed to a steel vertical keel 3) by the magnetic connector 7.

[0050] Compared to the past, where wall panels were directly fixed to the horizontal keel with structural adhesive, it is now much more difficult to remove the wall panels without damage once they are fixed. It is necessary to cut the structural adhesive to remove the wall panels, which increases the difficulty of wall panel removal and makes wall panel maintenance difficult.

[0051] The newly designed magnetic connector 7 of this utility model solves the problem that the wall panel 2 is not easy to remove from the leveling keel after installation.

[0052] Reference Figures 1 to 14 In one embodiment, a prefabricated wall panel connection device further includes a joint sealant strip 8; the joint sealant strip 8 is used to be disposed between two adjacent wall panels 2.

[0053] In one embodiment, because the flatness of the wall surface 91 is sometimes low, wall panels cannot be directly installed. Therefore, a leveling joist is needed to install the wall panels. The leveling joist creates a cavity between the wall panel and the wall 9, which can accommodate electrical, water supply, and other pipelines. Previously, leveling joists were horizontally arranged. When a horizontally arranged joist encounters a vertically arranged pipeline X, the horizontal joist needs to be disconnected, making the installation of the leveling joist extremely troublesome. Therefore, the joist newly designed in this utility model is vertically arranged (in conjunction with...). Figure 7 , Figure 8 and Figure 13 (For understanding purposes), it will not conflict with the vertical pipeline X in terms of layout, facilitating the installation of the vertical keel 3 (i.e., the leveling keel) and the vertical pipeline X. In this utility model, the cavity between the wall panel 2 and the wall 9 only carries the vertical pipeline X; while the pipelines along the horizontal direction of the wall surface 91 of the wall 9 are run in the ground or ceiling (in conjunction with...). Figure 8 (This section discusses understanding the pipework X, the finished floor surface J, and the finished ceiling surface K.)

[0054] After the wall panel 2 of this utility model is installed, the connecting seat 11 and the first limiting member 12 are hidden in the structure. The connecting seat 11 and the first limiting member 12 cannot be seen from the outside of the wall panel 2. This design of this utility model ensures the aesthetics of the wall 9 and the wall surface 91 after decoration.

[0055] Another objective of this utility model is to provide an installation method for a prefabricated wall panel connection device, so as to reduce the installation difficulty of wall panels and improve the installation efficiency of wall panels.

[0056] Reference Figures 1 to 14 An installation method for a prefabricated wall panel connection device, based on the aforementioned prefabricated wall panel connection device, includes the following steps: S1. Install vertical keel 3, so that vertical keel 3 is directly or indirectly connected to wall 9; S2. Install the base 51 of the bottom component 5, so that the base 51 is connected to the vertical keel 3; Install the top bracket 61 of the top component 6 so that the top bracket 61 is connected to the vertical keel 3; S3. Install the connecting seat 11 on the set vertical keel 3; S4. Install the pre-designated wall panel 2; S41. Fix the magnetic connector 7 onto the wall panel 2; S42. Insert the bottom of the wall panel 2 into the third limiting groove 511 of the base 51; S43. Make the magnetic connector 7 on the wall panel 2 adhere and fix it to the set vertical keel 3; S5. Repeat steps S3 to S4 until all the connecting seats 11 and wall panels 2 are in place; Alternatively, repeat step S4 directly until all wall panels 2 are in place; S6. The first limiting member 12 is used to connect the connecting groove 21 on one side of the wall panel 2 to the second limiting groove C of the connecting seat 11, and the first limiting member 12 is prevented from falling out of the second limiting groove C by the locking of the second limiting member D, thereby realizing the limiting and fixing of the wall panel 2. S7. Insert caulking strip 8 between two adjacent wall panels 2; S8. Install the first cover 52 of the bottom component 5, so that the first cover 52 is connected to the base 51; Install the second cover 62 of the top assembly 6 so that the second cover 62 is connected to the top seat 61; S9. Complete the prefabricated decoration of the walls.

[0057] In one embodiment, in step S1, the vertical keel 3 is indirectly connected to the wall 8 via a fixing component 4; step S1 includes the following steps: S11. Fix the plastic expansion tube 422 into the mounting hole on the wall 9; S12. After the first fastener 421 passes through the first connecting hole 411, it is connected to the plastic expansion tube 422, and the connector 41 is locked and connected to the wall 9. S13. The vertical keel 3 is fitted onto the outer side of the connector 41, and the vertical keel 3 and the connector 41 are locked together by the second fastener 43. S14. Complete the indirect connection of the vertical keel 3 to the wall 9.

[0058] In the first embodiment (in combination) Figure 2 (For understanding), in step S6, if the second limiting member D is a protrusion on the first L-shaped plate 111, and only one connecting seat 11 is provided on a vertical keel 3, then when installing the first limiting member 12, the first limiting member 12 can be inserted from the connecting groove 21 at the top of one side of the wall panel 2, and then the first limiting member 12 is adjusted to connect with the second limiting groove C, and the second limiting member D is made to block the first limiting member 12 to prevent the first limiting member 12 from falling out of the second limiting groove C (such as falling down), and finally, the wall panel 2 is fixed in place.

[0059] If a vertical keel 3 has multiple connecting seats 11 from top to bottom, when installing the first limiting member 12, it can also be inserted from the connecting groove 21 at the top of one side of the wall panel 2. However, the first limiting member 12 needs to be adjusted one by one to connect with the corresponding connecting seat 11. For example, if the bottom connecting seat 11 requires the first limiting member 12, after the first limiting member 12 is inserted from the connecting groove 21 at the top of one side of the wall panel 2, the wall panel 2 needs to be pulled "outward" (the wall panel is relatively large and thin, and there is a possibility of local elastic deformation adjustment) so that the first limiting member 12 has enough space to "skip" the connecting seat 11 above (to avoid being blocked by the second limiting member on the upper connecting seat and unable to fall), so that it can be smoothly adjusted along the connecting groove 21 to the bottom and connect with the second limiting groove C of the corresponding connecting seat 11 below.

[0060] In the second embodiment (in combination with) Figure 1 (For understanding), in step S6, if the second limiting member D is a limiting member independent of the connecting seat 11 (such as a magnetic limiting block), and a vertical keel 3 has multiple connecting seats 11 from top to bottom, then when installing the first limiting member 12, the first limiting member 12 can be inserted from the connecting groove 21 at the top of one side of the wall panel 2. The first limiting member 12 can slide smoothly down the connecting groove 21 to connect with the corresponding second limiting groove C below. When the first limiting member 12 is adjusted down to connect with the corresponding second limiting groove C, the second limiting member D is then installed on the vertical keel 3 through the "board gap between the wall panels" so that the second limiting member D is located below the second limiting groove C of the corresponding connecting seat 11, thereby preventing the first limiting member 12 from falling out of the corresponding second limiting groove C.

[0061] Combination Figure 13 To illustrate this, in one embodiment, two wall panels 2 are indirectly connected to the wall 9 as an example, so that people can understand how the prefabricated wall panel connection device of this utility model facilitates the installation of the wall panel 2.

[0062] Specifically, the vertical keel 3 is provided with five keels, from right to left (see reference). Figure 13 The M (illustrated) represent the first vertical keel, the second vertical keel, the third vertical keel, the fourth vertical keel N, and the fifth vertical keel P; these six vertical keels 3 are fixed to the wall 9 by fixing components 4 respectively; The base 51 is arranged horizontally and connected to the five vertical keels 3 one by one; The top seat 61 is arranged horizontally and connected to the five vertical keels 3 one by one; A connecting seat 11 is installed on the first vertical keel, and a connecting seat 11 is installed on the third vertical keel; A magnetic connector 7 is provided on the back of the first wall panel R, wherein the magnetic connector 7 is connected to the back of the first wall panel R by structural adhesive Y. Insert the bottom of the first wall panel R into the third limiting groove 511 of the base 51, so that the magnetic connector 7 on the back of the first wall panel R is attracted and fixed to the second vertical keel. Push the first wall panel R to the right (slightly) so that the right side of the first wall panel R is connected to the first limiting groove B of the connecting seat 11 on the first vertical keel; the left side of the first wall panel R rests on the connecting seat 11 on the third vertical keel; the top and back of the first wall panel R rests on the top seat 61. A connecting seat 11 is installed on the fifth vertical keel P; A magnetic connector 7 is provided on the back of the second wall panel Q, wherein the magnetic connector 7 is connected to the back of the second wall panel R by structural adhesive Y. Insert the bottom of the second wall panel Q into the third limiting groove 511 of the base 51, so that the magnetic connector 7 on the back of the second wall panel Q is attracted and fixed to the fourth vertical keel N. Push the second wall panel Q to the right (slightly) so that the right side of the second wall panel Q is connected to the first limiting groove B of the connecting seat 11 on the third vertical keel; the left side of the second wall panel Q rests on the connecting seat 11 on the fifth vertical keel P; the top and back of the second wall panel Q rests on the top seat 61. The first limiting member 12 is inserted into the connecting groove 21 on the left side of the first wall panel R, and then moved down to connect with the second limiting groove C of the connecting seat 11 on the third vertical keel, thereby fixing the first wall panel R. Similarly, the first limiting member 12 is inserted into the connecting groove 21 on the left side of the second wall panel Q, and then moved down to connect with the second limiting groove C of the connecting seat 11 on the fifth vertical keel P, thereby fixing the second wall panel Q. Insert caulking strip 8 between the first wall panel R and the second wall panel Q; Next, install the first cover 52 and connect it to the base 51; then install the second cover 62 and connect it to the top seat 61.

[0063] Finally, the prefabricated decoration of wall 9 and wall surface 91 was completed.

[0064] When there are three or more wall panels to be installed, this utility model can still install the wall panel even if a wall panel in a certain position is skipped and not installed temporarily. Unlike traditional "I"-shaped integrated connectors, it will not have the problem of wall panels not being able to be installed.

[0065] In another embodiment, the wall panel 2 is installed from left to right. (Combined with...) Figure 13For understanding, for example, there are five vertical keels 3, from left to right: the fifth vertical keel P, the fourth vertical keel N, the third vertical keel, the second vertical keel, and the first vertical keel; after each vertical keel 3, base 51, and top seat 61 are installed in place, they are: First, install the connector 11 on the fifth vertical keel P; Install the second wall panel Q; Then install the connecting seat 11 on the third vertical keel, so that the first limiting groove B of the connecting seat 11 is connected to the right side of the second wall panel Q (the second wall panel Q remains relatively stationary). Next, install the first wall panel R; Then install the connector 11 on the first vertical keel, so that the first limiting groove B of the connector 11 is connected to the right side of the first wall panel R (the first wall panel R remains relatively stationary). After all wall panels 2 and connecting seats 11 are in place, the first limiting member 12 is installed so that the first limiting member 12 can limit and fix the wall panels 2. Then install the sealant strip 8; After the sealant strip 8 is installed, install the first cover part 52 and the second cover part 62. Finally, the prefabricated decoration of the walls and surfaces is completed.

[0066] In one embodiment, the step of removing wall panel 2 includes the following steps: A1. Remove the second cover 62 of the top assembly 6 so that the second cover 62 is no longer connected to the top seat 61; Remove the joint sealant strip 8 so that it is no longer installed between the wall panels; A2. Lift the first limiting member 12 from bottom to top along the connecting groove 21 so that the first limiting member 12 no longer connects the second limiting groove C of the connecting seat 11 with the connecting groove 21 on one side of the wall panel 2. A3. Lift the wall panel 2 upwards so that the bottom of the wall panel 2 is disengaged from the third limiting groove 511 of the base 51; A4. Pull the wall panel 2 to one side (such as the left side) so that the other side of the wall panel 2 (such as the right side) is disengaged from the first limiting groove B of the connecting seat 11 at another set position, and the wall panel 2 can be removed.

[0067] When the wall panel 2 of this utility model needs maintenance, the corresponding wall panel 2 can be directly disassembled, without having to disassemble them one by one in reverse order to the corresponding wall panel position in the traditional way before the wall panel that needs to be replaced can be removed.
