Description

Technical Field

[0001] This invention relates to the field of prefabricated wall panel technology, and in particular to a prefabricated wall panel installation structure and construction method. Background Technology

[0002] To enhance the multi-element style of architectural decoration and improve the aesthetic appeal of the building structure, decorative wall panels need to be installed during the architectural renovation process. There are many types of decorative wall panels, generally divided into interior wall panels and exterior wall panels. The surface of the decorative wall panels is decorated with a variety of decorative paintings, and users can choose their favorite decorative paintings according to their own preferences.

[0003] Chinese utility model patent with publication number CN207582871U discloses an outdoor thermal insulation decorative wall panel installation structure, including a main wall and a number of thermal insulation decorative wall panels installed on the main wall. Each thermal insulation decorative wall panel has a snap-fit ​​groove at one end and a snap-fit ​​strip at the other end that is inserted into the snap-fit ​​groove of the adjacent thermal insulation decorative wall panel. The side of the thermal insulation decorative wall panel closest to the main wall is provided with a connector for fixed installation with the main wall.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: During daily use, the decorative layer on the surface of the decorative wall panel is easily graffitied, affecting its aesthetics. When using the aforementioned decorative wall panel, if a damaged or graffitied decorative wall panel is to be replaced individually, the surrounding wall panels need to be removed before the decorative wall panel to be replaced can be removed and replaced, which is a cumbersome operation. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a prefabricated wall panel installation structure and construction method.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a prefabricated wall panel installation structure, comprising an L-shaped block fixed to the wall surface and an installation block fixed to the surface of the decorative wall panel near the wall. An installation groove is provided on the side wall of the installation block away from the decorative wall panel. A movable groove with a width greater than the width of the installation groove and communicating with the installation groove is provided inside the installation block. A sliding block is provided in the movable groove and slidably engages with the movable groove. A limiting block is hinged to the top of the sliding block away from the decorative wall panel, abutting against the vertical portion of the L-shaped block. The side walls on both sides of the limiting block are respectively attached to the side walls on both sides of the installation groove. A driving assembly for driving the limiting block to rotate around the hinge axis between the limiting block and the sliding block is provided on the side of the decorative wall panel away from the wall. The distance between the hinge axis between the limiting block and the sliding block and the bottom surface of the limiting block is less than the distance between the side wall of the vertical portion of the L-shaped block near the wall and the wall.

[0007] By adopting the above technical solution, during use, the sidewall of the limiting block away from the wall panel abuts against the sidewall of the vertical part of the L-shaped block near the wall, and the sidewall of the decorative wall panel near the wall abuts against the sidewall of the vertical part of the L-shaped block away from the wall, thus enhancing the stability of the decorative wall panel during use. When a damaged decorative wall panel needs to be replaced, the operator only needs to use the drive component to drive the limiting block to rotate around the hinge axis between the limiting block and the sliding block. The restriction of the distance between the bottom surface of the limiting block and the hinge axis allows the limiting block to rotate around the hinge axis and retract into the mounting groove until the height of the limiting block is greater than the height of the top of the vertical part of the L-shaped block. At this point, the operator can easily disassemble and replace the damaged decorative wall panel individually.

[0008] Furthermore, an outer receiving groove is provided on the side wall of the decorative wall panel away from the wall, and an inner receiving groove is provided inside the decorative wall panel that communicates with the outer receiving groove. The driving assembly includes an operating block that engages with the outer receiving groove, a first spring that is fixed to both the side wall of the inner receiving groove near the wall and the side of the operating block near the wall, and a pull rope that is fixed to the side wall of the operating block near the wall. The pull rope passes through the decorative wall panel and is fixed to the side wall of the limiting block near the wall.

[0009] By adopting the above technical solution, when the driving component drives the limiting block to rotate around the hinge axis between the limiting block and the sliding block, the operator only needs to pull the operating block toward the side away from the wall, so that the pull rope pulls the limiting block and makes the limiting block rotate around its hinge axis until the limiting block rotates into the installation groove, so that the operator can disassemble and replace the decorative wall panel.

[0010] Furthermore, a second spring is fixed between the bottom wall of the movable groove and the bottom surface of the sliding block, and a magnet that is magnetically attracted to the limiting block is embedded in the side wall of the mounting block near the wall, and the magnet is located near the bottom of the mounting block.

[0011] By adopting the above technical solution, the magnet has a good attraction effect on the limiting block, which enhances the stability of the connection between the limiting block and the vertical part of the L-shaped block. The setting of the second spring enhances the stability of the sliding block in the movable groove.

[0012] Furthermore, a fixing rod is fixed to the top of the mounting block, and a fixed pulley that cooperates with and tensions the pull rope is rotatably installed at the end of the fixing rod. The connection point between the pull rope and the limiting block is located near the bottom of the limiting block.

[0013] By adopting the above technical solution, the setting of the fixed pulley ensures the stability of the pull rope during the movement of the limit block, and reduces the probability of the pull rope being scratched by the edge of the mounting groove during the movement of the limit block.

[0014] Furthermore, the decorative wall panel is provided with an annular groove that communicates with the outer receiving groove and is located on the side of the inner receiving groove away from the wall. An annular airbag is attached and fixed to the inner wall of the annular groove. An inflation tube is fixed and connected to the side of the annular airbag away from the wall. The inflation tube passes through the operating block and is gap-fitted with the operating block. A cap that is threadedly connected to the inflation tube is provided on the side of the inflation tube away from the wall.

[0015] By adopting the above technical solution, in order to facilitate the staff to pull the operating block in the outer receiving groove toward the side away from the wall, the staff only needs to inflate the annular airbag through the inflation tube. After the annular airbag inflates, it can lift the operating block out of the outer receiving groove, thereby facilitating the staff to pull the operating block located in the outer receiving groove, and causing the pull rope to pull the limiting block until the limiting block separates from the L-shaped block.

[0016] Furthermore, the cap operating block has a receiving hole for accommodating the cap on the side away from the wall, and a decorative cover plate is fixed on the side of the cap away from the wall, which is coaxially arranged with the operating block. The surface of the decorative cover plate on the side near the wall is flush with the surface of the decorative wall panel on the side away from the wall.

[0017] Furthermore, the decorative wall panel includes a base plate and a decorative panel fixed to the surface of the base plate away from the wall. The operating block includes a base block and a decorative layer fixed to the surface of the base block away from the wall. The thickness of the decorative cover plate is 1mm. The intersection between the side wall of the decorative cover plate away from the wall and the side wall of the decorative cover plate is rounded. The decorative cover plate is provided with an internal hexagonal groove at the position corresponding to the cap.

[0018] By adopting the above technical solution, the decorative cover plate is thinner, and its surface is printed with decorative patterns of the same type and color as the decorative wall panel, ensuring the consistency and aesthetics of the decorative wall panel structure. The rounded corners make the connection between the decorative cover plate and the decorative wall panel smoother and more natural. The internal hexagonal slot allows workers to easily rotate the decorative cover plate using an internal hexagonal wrench, reducing the difficulty of rotating the cover plate.

[0019] Furthermore, a chamfer is provided at the intersection between the bottom surface of the limiting block and the side wall of the limiting block away from the decorative wall panel.

[0020] By adopting the above technical solution, the chamfer setting allows workers to easily remove and replace damaged decorative wall panels by simply pressing and pushing the panel towards the wall. When the chamfer on the limiting block contacts the sidewall of the L-shaped block's vertical section away from the wall, it drives the limiting block to slide upwards along the mounting groove. Simultaneously, the sliding block slides upwards along the movable groove until the bottom surface of the limiting block aligns with the top of the L-shaped block's vertical section. Workers then continue pushing the decorative wall panel towards the wall. When the sidewall of the limiting block away from the wall aligns with the sidewall of the L-shaped block's vertical section near the wall, the sidewall of the decorative wall panel near the wall aligns with the sidewall of the L-shaped block's vertical section away from the wall, thus completing the installation of the decorative wall panel.

[0021] This application also discloses a construction method for a prefabricated wall panel installation structure, comprising the following steps:

[0022] S1. When installing decorative wall panels on a wall, the L-shaped blocks must first be fixed to the wall with screws or expansion bolts.

[0023] S2. Assemble the decorative wall panel, mounting block, limiting block, fixed pulley, and drive assembly. Press and push the decorative wall panel towards the side closest to the wall. After the chamfer on the limiting block touches the side wall of the vertical part of the L-shaped block away from the wall, it can drive the limiting block to slide upward along the mounting groove. At the same time, the sliding block slides upward along the movable groove. After the bottom surface of the limiting block is in contact with the top of the vertical part of the L-shaped block, the worker continues to push the decorative wall panel towards the side closest to the wall. When the side wall of the limiting block away from the wall is in contact with the side of the vertical part of the L-shaped block close to the wall, the side wall of the decorative wall panel close to the wall is in contact with the side of the vertical part of the L-shaped block away from the wall, and the installation of the decorative wall panel is completed.

[0024] S3. When disassembling and replacing the decorative wall panel, the worker needs to rotate the decorative cover plate through the internal hexagonal groove until the cap separates from the inflation tube. At this time, the worker can inflate the annular airbag through the inflation tube, causing the annular airbag to inflate. The annular airbag moves the operating block from the outer receiving groove to the side away from the wall. The worker can then pull the pull rope through the operating block, causing the limiting block to move around its hinge axis into the installation groove until the height of the limiting block is greater than the height of the top of the vertical part of the L-shaped block. The worker can then easily remove the decorative wall panel from the wall. Repeat step S2 to replace the decorative wall panel that needs to be replaced.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. In this application, when it is necessary to replace a damaged decorative wall panel, the worker only needs to drive the limiting block to rotate around the hinge axis between the limiting block and the sliding block through the drive component. The limitation of the distance between the bottom surface of the limiting block and the hinge axis of the limiting block allows the limiting block to rotate around the hinge axis and retract into the mounting groove until the height of the limiting block is greater than the height of the top of the vertical part of the L-shaped block. Then the worker can easily disassemble and replace the damaged decorative wall panel individually.

[0027] 2. This application simplifies the disassembly of decorative wall panels and reduces the difficulty of replacing damaged decorative wall panels. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] like Figure 1-4As shown in the figure, this application discloses an assembled wall panel installation structure, including an L-shaped block 1, an installation block 2, and a driving assembly 3. The L-shaped block 1 is a block structure with an L-shaped cross-section, and the horizontal end of the L-shaped block 1 is fixed to the surface of the wall 4. The installation block 2 is a block structure with a rectangular cross-section. One side wall of the installation block 2 is fixed to the surface of the decorative wall panel 5 near the wall 4. The decorative wall panel 5 is arranged parallel to the wall 4. The distance between the side wall of the installation block 2 near the wall 4 and the wall 4 is less than the distance between the vertical part of the L-shaped block 1 and the wall 4. In this embodiment, an installation groove 21 is provided on the side wall of the installation block 2 away from the decorative wall panel 5. An movable groove 22 with a width greater than the width of the installation groove 21 and communicating with the installation groove 21 is provided in the installation block 2. A sliding block 221 that slides with the movable groove 22 is provided in the movable groove 22.

[0035] The top of the sliding block 221, away from the decorative wall panel 5, is hinged to a limiting block 6 that abuts against the vertical part of the L-shaped block 1. The side walls on both sides of the limiting block 6 are respectively attached to the side walls on both sides of the mounting groove 21. The distance between the hinge axis between the limiting block 6 and the sliding block 221 and the bottom surface of the limiting block 6 is less than the distance between the side wall of the vertical part of the L-shaped block 1 near the wall 4 and the wall 4.

[0036] An outer receiving groove 51 is formed on the side wall of the decorative wall panel 5 away from the wall 4, and an inner receiving groove 52 communicating with the outer receiving groove 51 is provided inside the decorative wall panel 5. The driving component 3 is located on the side of the decorative wall panel 5 away from the wall 4, and is used to drive the limiting block 6 to rotate around the hinge axis between the limiting block 6 and the sliding block 221. The driving component 3 includes an operating block 31 that engages with the outer receiving groove 51, a first spring 32 that is fixed to both the side wall of the inner receiving groove 52 near the wall 4 and the side of the operating block 31 near the wall 4, and a pull rope 33 that is fixed to the side wall of the operating block 31 near the wall 4. The pull rope 33 passes through the decorative wall panel 5 and is fixed to the side wall of the limiting block 6 near the wall 4. A second spring 222 is fixed between the bottom wall of the movable groove 22 and the bottom surface of the sliding block 221. A magnet 23 that is magnetically attracted to the limiting block 6 is embedded in the side wall of the mounting block 2 near the wall 4, and the magnet 23 is located near the bottom of the mounting block 2.

[0037] A fixing rod 24 is fixed to the top of the mounting block 2. A fixed pulley 241 is rotatably mounted at the end of the fixing rod 24, which cooperates with and tightens the pull rope 33. The connection point between the pull rope 33 and the limiting block 6 is located near the bottom of the limiting block 6. During use, the side wall of the limiting block 6 away from the wall panel abuts against the side wall of the vertical part of the L-shaped block 1 near the wall 4, and the side wall of the decorative wall panel 5 near the wall 4 abuts against the side wall of the vertical part of the L-shaped block 1 away from the wall 4, thus enhancing the stability of the decorative wall panel 5 during use. When a damaged decorative wall panel 5 needs to be replaced, the worker only needs to pull the operating block 31 toward the side away from the wall 4, so that the pull rope 33 pulls the limiting block 6 and makes the limiting block 6 rotate around its hinge axis. The distance between the bottom surface of the limiting block 6 and the hinge axis of the limiting block 6 is limited, so that the limiting block 6 can rotate around the hinge axis and retract into the mounting groove 21 until the height of the limiting block 6 is greater than the height of the top of the vertical part of the L-shaped block 1, so that the worker can disassemble and replace the decorative wall panel 5.

[0038] To facilitate the removal of the operating block 31 from the outer receiving groove 51 and the pulling of the pull rope 33 via the operating block 31, the decorative wall panel 5 is provided with an annular groove 53 that communicates with the outer receiving groove 51 and is located on the side of the inner receiving groove 52 away from the wall 4. An annular airbag 7 is attached and fixed to the inner wall of the annular groove 53. An inflation tube 71 is fixed and connected to the side of the annular airbag 7 away from the wall 4. The inflation tube 71 passes through the operating block 31 and is clearance-fitted with the operating block 31. A cap 711 is provided on the side of the inflation tube 71 away from the wall 4 and is threadedly connected to the inflation tube 71. A receiving hole 310 for receiving the cap 711 is provided on the side of the operating block 31 away from the wall 4. A decorative cover plate 8 is fixed on the side of the cap 711 away from the wall 4 and is coaxially arranged with the operating block 31. The surface of the decorative cover plate 8 near the wall 4 is flush with the surface of the decorative wall panel 5 away from the wall 4.

[0039] In this embodiment, a chamfer 61 is provided at the intersection of the bottom surface of the limiting block 6 and the side wall of the limiting block 6 away from the decorative wall panel 5. The decorative wall panel 5 includes a base plate 54 and a decorative plate 55 fixed to the surface of the base plate 54 away from the wall 4. The operating block 31 includes a base block 311 and a decorative layer 312 fixed to the surface of the base block 311 away from the wall 4. The thickness of the decorative cover plate 8 is 1mm. A rounded corner 81 is provided at the intersection of the side wall of the decorative cover plate 8 away from the wall 4 and the side wall of the decorative cover plate 8. An internal hexagonal groove 82 is provided at the corresponding position of the decorative cover plate 8 and the cap 711. The decorative cover plate 8 has a small thickness, and the surface of the decorative cover plate 8 is printed with a decorative pattern of the same type and color as the surface of the decorative wall panel 5, ensuring the consistency and aesthetics of the structure of the decorative wall panel 5. The rounded corner 81 makes the connection between the decorative cover plate 8 and the decorative wall panel 5 smoother and more natural. To facilitate the operation block 31 in the outer receiving groove 51 to be pulled away from the wall 4, the operator only needs to use the hex wrench that matches the hex socket 82 to rotate the decorative cover plate 8. Then, the air can be inflated into the annular airbag 7 through the air inflating pipe 71. After the annular airbag 7 inflates, it can lift the operation block 31 out of the outer receiving groove 51, so that the operator can pull the operation block 31 in the outer receiving groove 51 and cause the pull rope 33 to pull the limiting block 6 until the limiting block 6 separates from the L-shaped block 1.

[0040] The operating principle of the prefabricated wall panel installation structure in this embodiment is as follows: During use, the side wall of the limiting block 6 away from the wall panel abuts against the side wall of the vertical part of the L-shaped block 1 near the wall 4, and the side wall of the decorative wall panel 5 near the wall 4 abuts against the side wall of the vertical part of the L-shaped block 1 away from the wall 4, thus enhancing the stability of the decorative wall panel 5 during use. When a damaged decorative wall panel 5 needs to be replaced, the operator only needs to pull the operating block 31 towards the side away from the wall 4, so that the pull rope 33 pulls the limiting block 6 and causes the limiting block 6 to rotate around its hinge axis. The distance between the bottom surface of the limiting block 6 and the hinge axis of the limiting block 6 is restricted, allowing the limiting block 6 to rotate around the hinge axis and retract into the mounting groove 21 until the height of the limiting block 6 is greater than the height of the top of the vertical part of the L-shaped block 1, so that the operator can disassemble and replace the decorative wall panel 5.

[0041] This embodiment also discloses a construction method for a prefabricated wall panel installation structure, including the following steps:

[0042] S1. When installing decorative wall panels 5 on wall 4, the L-shaped block 1 must first be fixed to wall 4 with screws or expansion bolts.

[0043] S2. Assemble the decorative wall panel 5, mounting block 2, limiting block 6, fixed pulley 241, and drive assembly 3. Press and push the decorative wall panel 5 towards the side closest to the wall 4. After the chamfer 61 on the limiting block 6 touches the side wall of the vertical part of the L-shaped block 1 away from the wall 4, it can drive the limiting block 6 to slide upward along the mounting groove 21. At the same time, the sliding block 221 slides upward along the movable groove 22. After the bottom surface of the limiting block 6 is in contact with the top of the vertical part of the L-shaped block 1, the worker continues to push the decorative wall panel 5 towards the side closest to the wall 4. When the side wall of the limiting block 6 away from the wall 4 is in contact with the side of the vertical part of the L-shaped block 1 close to the wall 4, the side wall of the decorative wall panel 5 close to the wall 4 is in contact with the side of the vertical part of the L-shaped block 1 away from the wall 4, and the installation of the decorative wall panel 5 is completed.

[0044] S3. When disassembling and replacing the decorative wall panel 5, the worker needs to rotate the decorative cover plate 8 through the internal hexagonal groove 82 until the cap 711 separates from the inflation tube 71. At this time, the worker can inflate the annular airbag 7 through the inflation tube 71, causing the annular airbag 7 to inflate. The annular airbag 7 moves the operating block 31 from the outer receiving groove 51 toward the side away from the wall 4. The worker can then pull the pull rope 33 through the operating block 31, causing the limiting block 6 to move around its hinge axis into the mounting groove 21. When the height of the limiting block 6 is greater than the height of the top of the vertical part of the L-shaped block 1, the worker can easily remove the decorative wall panel 5 from the wall 4. Repeat the steps of S2 to replace the decorative wall panel 5 that needs to be replaced.

When the side wall of the limiting block (6) away from the wall (4) is in contact with the side of the vertical part of the L-shaped block (1) close to the wall (4), the side wall of the decorative wall panel (5) close to the wall (4) is in contact with the side of the vertical part of the L-shaped block (1) away from the wall (4). With one side attached, the installation of the decorative wall panel (5) is completed; S3, when disassembling and replacing the decorative wall panel (5), the worker needs to rotate the decorative cover plate (8) through the inner hexagonal groove (82) until the cap (711) separates from the inflation tube (71). At this time, the worker can inflate the annular airbag (7) through the inflation tube (71) and make the annular airbag (7) bulge. The annular airbag (7) moves the operating block (31) from the outer receiving groove (51) toward the side away from the wall (4). The worker can then pull the pull rope (33) through the operating block (31) so that the limiting block (6) moves around its hinge axis into the installation groove (21) until the height of the limiting block (6) is greater than the height of the top of the vertical part of the L-shaped block (1). The worker can then easily remove the decorative wall panel (5) from the wall (4). Repeat the steps of S2 to replace the decorative wall panel (5) that needs to be replaced.
