Technical Field
[0001] This invention relates to the field of building exterior wall decorative panels, and more specifically, to a fixing device for prefabricated building exterior wall decorative panels. Background Technology
[0002] Currently, the most common exterior wall decorative panels on the market include stone panels, metal panels, and composite panels. In actual construction, the "dry hanging method" is a commonly used construction method for stone panels. By pre-installing metal keels (such as galvanized steel or aluminum alloy) and hangers on the exterior wall of the building, the decorative panels can be suspended and fixed to the outside of the base wall.
[0003] The most common type of fastener is the T-shaped clip. In actual construction, grooves are made on the top and bottom sides of the board, and then the connecting ends of the T-shaped clips are inserted into the corresponding grooves of the two boards. A certain amount of adhesive material is then injected into the grooves, and the board can be indirectly fixed to the keel by the T-shaped clips.
[0004] However, this installation method is quite difficult to replace when removing exterior wall panels. Not only is it necessary to remove the adhesive material in the gaps between the panels, but it is also necessary to cut off the T-shaped clips in order to remove the panels without damage, or the panels can only be removed by breaking them. This will significantly reduce the recycling value of the panels, especially marble panels. For commercial buildings such as shopping streets and hotels that need to frequently renovate their facades to maintain their brand image and competitiveness, this is not only inconsistent with the concept of environmental protection, but also significantly increases the renovation cost. Summary of the Invention
[0005] The present invention provides a prefabricated building exterior wall decorative panel fixing device, which aims to solve the following problem: In the existing "dry hanging method" for decorative panel installation, the metal keel and hanger components used not only require the removal of the adhesive material in the gaps between the panels when replacing the exterior wall decorative panels, but also require cutting off the T-shaped clips to remove the panels without damage. This makes the replacement difficult, or the panels can only be broken and removed, which greatly reduces the recycling value of the panels, not only does it not conform to the concept of environmental protection, but also significantly increases the renovation cost.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a fixing device for prefabricated building exterior wall decorative panels, comprising: The exterior wall has several decorative panels arranged in an array on its outer side; The keel consists of several columns fixedly installed on the outside of the exterior wall. All columns are vertically installed and arranged in an array. Several horizontal columns are installed horizontally on the outside of the columns and arranged in an array. Several support shafts are arranged in an array on the horizontal columns. The support mechanism includes a support seat movably sleeved on the support shaft, a support cylinder fixedly installed on the outside of the support seat, a connecting rod slidably installed on the support cylinder, and a plug-in seat installed at the end of the connecting rod away from the support seat. The decorative panel includes a panel body, and two back bolt buckles are arranged vertically on the inner side of the panel body. The back bolt buckles engage with the corresponding plug-in seats.
[0007] In a preferred embodiment, a through groove is provided at one end of the support cylinder near the support base, and a wedge plate is slidably disposed in the through groove. The end of the connecting rod near the support base is spherically shaped, and the outer side of the wedge plate abuts against the end of the connecting rod near the support base.
[0008] In a preferred embodiment, a positioning mechanism is provided on the outer side of the column. The positioning mechanism includes several positioning cylinders, on which rotating rods are movably mounted. A hollow shaft is rotatably mounted on the end of the positioning cylinder away from the corresponding column. A rectangular groove is provided on the hollow shaft. A rectangular rod is provided on the rotating rod, and the rectangular rod is adapted to the rectangular groove. A lever is fixedly sleeved on the hollow shaft. A U-shaped hook is provided on the wedge plate, and the U-shaped hook is adapted to the corresponding lever.
[0009] In a preferred embodiment, a spring is provided inside the positioning cylinder, and the spring abuts against the rotating rod. The positioning cylinder is provided with two sets of slots, which are used to fix the angle of the rotating rod after rotation.
[0010] In a preferred embodiment, two guide sleeves are provided on the column, and a limit rod is slidably provided on the guide sleeve. An L-shaped rod is provided at the end of the limit rod away from the corresponding support seat, and a sliding frame is provided at one end of the L-shaped rod. The sliding frame is movably connected to the rotating rod.
[0011] In a preferred embodiment, the support base includes a horn groove that communicates with a limiting hole, and a limiting rod that is adapted to the corresponding limiting hole.
[0012] In a preferred embodiment, the support cylinder is provided with a guide groove, and the connecting rod is provided with a guide bar, which is adapted to the guide groove.
[0013] In a preferred embodiment, a connecting strip is provided on the side of the support base away from the horizontal column, and a connecting groove is provided on the side of the wedge plate near the support base, with the connecting strip and the connecting groove being adapted to each other.
[0014] In a preferred embodiment, two adjacent wedge plates on the same column are arranged symmetrically about the axis of their corresponding positioning cylinders, and two adjacent L-shaped rods on the same column are arranged symmetrically about the axis of their corresponding positioning cylinders.
[0015] In a preferred embodiment, the back bolt buckle is provided with an adjusting bolt, which is used to adjust the position of the sheet body.
[0016] The beneficial effects of this invention are as follows: 1. This invention, by setting up a support mechanism and a positioning mechanism in conjunction with a back bolt buckle, can not only firmly fix the decorative panels to the exterior wall without using hangers such as "T-shaped buckles" that would securely connect the panels to each other, but also allow for quick and non-destructive removal of the panels when partial replacement is required. This effectively improves construction efficiency and panel recycling rate, thereby further reducing the cost of building renovation.
[0017] 2. By setting up a support base that provides rotational freedom for the board, the board to be replaced can be pulled out horizontally in a "cross" state with the surrounding boards when partially replacing the board. This gives the operator enough operating space to grab the two sides of the board. At the same time, the board below can be used to provide some support for the board to be replaced during the removal process. This not only effectively reduces the difficulty of operation for the operator, but also significantly reduces the risk of the board slipping and being damaged, and further improves the recycling rate.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0021] The exterior walls of commercial buildings such as shopping streets and hotels often require landscape lighting and festive decorations, which can easily scratch or damage the stone slabs during these construction operations. Meanwhile, with rapid economic development, storefronts in commercial streets are frequently transferred and renovated, and construction efficiency significantly impacts opening times. Therefore, efficient replacement devices for decorative panels are urgently needed.
[0022] Example 1 (refer to the appendix of the instruction manual) Figure 1 and Figure 10 This embodiment proposes a prefabricated building exterior wall decorative panel fixing device to solve the problem that in the existing "dry-hanging method" for decorative panel installation, the metal keel and hanger components used not only require removing the adhesive material between the panels when replacing the exterior wall decorative panels, but also cutting off the T-shaped clips to remove the panels without damage. This makes replacement difficult, or it may only require breaking the panels for removal, which significantly reduces the recycling value of the panels, not only failing to meet environmental protection standards, but also significantly increasing renovation costs. The device includes: The outer wall 1 has several decorative panels 5 arranged in an array on its outer side; It should be noted that exterior walls constructed using the "dry-hanging method" are mostly made of stone slabs, the most common being marble decorative slabs. Some high-end marble decorative slabs have high recycling value.
[0023] The keel 2 includes several columns 21 fixedly installed on the outside of the outer wall 1. The columns 21 are all vertically installed and arranged in an array. Several horizontal columns 22 are horizontally installed on the outside of the columns 21 and arranged in an array. Several support shafts 23 are arranged in an array on the horizontal columns 22. It should be noted that the arrangement of the keel 2 is a prerequisite for construction. The columns 21 and the horizontal columns 22 can be fixed to the exterior wall 1 by welding or bolting. Similarly, the support shaft 23 can be fixed to the horizontal column 22 in a similar way. Furthermore, the number, installation position, and spacing of the columns 21, horizontal columns 22, and support shafts 23 are all adapted to the specifications of the decorative panel 5.
[0024] The support mechanism 3 includes a support seat 31 movably sleeved on the support shaft 23. A support cylinder 32 is fixedly installed on the outside of the support seat 31. A connecting rod 33 is slidably installed on the support cylinder 32. A plug-in seat 34 is installed at the end of the connecting rod 33 away from the support seat 31. The decorative panel 5 includes a panel body 51. Two back bolt buckles 52 are arranged vertically on the inner side of the panel body 51. The back bolt buckles 52 are engaged with the corresponding plug-in seats 34.
[0025] It should be noted that after the decorative panel 5 is installed, the connecting rod 33 is located at the farthest end from the support base 31, and the connecting rod 33 is fixed by the wedge plate 35. The distance that the connecting rod 33 can slide in the support cylinder 32 is the operating space range of the worker. Its specific size can be designed according to actual needs. It is a mature technology well known to those in the art, and will not be described in detail in this embodiment.
[0026] Refer to the instruction manual appendix Figure 1 and Figure 10 In this embodiment, a through groove is provided at one end of the support cylinder 32 near the support base 31, and a wedge plate 35 is slidably disposed in the through groove. The end of the connecting rod 33 near the support base 31 is spherically disposed, and the outer side of the wedge plate 35 abuts against the end of the connecting rod 33 near the support base 31.
[0027] It should be noted that the wedge plate 35 is hollowed out to reduce weight and save material costs. The specific dimensions of the wedge plate 35 can be modified according to the actual situation. This is a mature technology well known to those in the art, and will not be described in detail in this embodiment.
[0028] In this embodiment, the specific implementation scenario is as follows: In the renovation of decorative panels, there are usually two situations. The first is complete replacement, such as replacing all the decorative panels on an entire wall or even the entire building facade. In this case, the staff can disassemble and install them step by step from top to bottom. The other is partial replacement, which is common in some office buildings, apartments and other buildings, because each floor of the building may be an independent hotel or company. These companies usually install signs on the facade of the corresponding floor or install distinctive panel bodies 51 to improve recognition. Therefore, only partial replacement of panel bodies 51 can be carried out. When installing the plate body 51, a certain gap is usually left between adjacent plate bodies 51. These gaps are usually sealed with sealant or other materials. First, remove the adhesive at the joints between the plate bodies 51. Then, the worker holds a pry bar in each hand. The front end of the pry bar has a fork-like structure. By engaging the two pry bars with the two ends of the rotating rod 42 respectively, and then pushing the rotating rod 42 inward in sync, the rotating rod 42 can slide inward and finally disengage from the slot on the positioning cylinder 41. At this time, the hollow shaft 44 is unlocked. Then, the worker rotates the two pry bars clockwise, which can drive the rotating rod 42 and the lever 45 to rotate synchronously. At this time, the lever 45 will push the two wedge plates 35 to slide out of the corresponding through groove in sync through the cooperation of the U-shaped hook 36, thereby releasing the locking of the convex surface of the wedge plate 35 to the connecting rod 33. Furthermore, when the operator rotates the rotating rod 42 clockwise to its maximum rotatable angle, the pry bar is retracted. The spring 43 pushes the rotating rod 42 back into another set of slots. At this point, the operator can retract the pry bar. The maximum diameter of the pry bar is less than the gap between two adjacent plate bodies 51. At this point, the plate body 51 is in the unlocked state. By pushing the plate body 51 inward, the operator can separate this plate body 51 from the surrounding plate bodies 51. Then, by lifting this plate body 51 upward, the back bolt buckle 52 can be disengaged from the connector 34. At this point, the plate body 51 that needs to be replaced can be removed without damage without affecting the surrounding plate bodies 51. When installing a new plate body 51, the above steps are reversed.
[0029] Example 2, based on Example 1, proposes a positioning mechanism 4 to address the problem in the prior art where the fixed-angle support cylinder 32 makes it difficult for workers to remove the partially replaced panel body 51. This requires workers to grasp the two sides of the panel body 51, rotate it to an inclined angle, and then remove it from the gap between the surrounding panel bodies 51. Furthermore, for some heavier panel bodies 51, workers find it difficult to remove them independently. Alternatively, two people can use suction cups to directly adhere to the outer surface of the panel body 51. However, this requires the outer surface of the panel body 51 to be flat and clean. When encountering panel bodies 51 with dirt, such as those on the exterior of buildings above open-air barbecue restaurants, or those with rough surfaces due to acid rain corrosion, it is difficult to ensure the stability of the suction cups, easily causing the panel body 51 to fall off during operation and resulting in damage.
[0030] Refer to the instruction manual appendix Figure 4 and Figure 5In this embodiment, a positioning mechanism 4 is provided on the outer side of the column 21. The positioning mechanism 4 includes several positioning cylinders 41. A rotating rod 42 is movably provided on the positioning cylinder 41. A hollow shaft 44 is rotatably provided at the end of the positioning cylinder 41 away from the corresponding column 21. A rectangular groove is provided on the hollow shaft 44. A rectangular rod is provided on the rotating rod 42. The rectangular rod is adapted to the rectangular groove. A lever 45 is fixedly sleeved on the hollow shaft 44. A U-shaped hook 36 is provided on the wedge plate 35. The U-shaped hook 36 is adapted to the corresponding lever 45.
[0031] It should be noted that the length of the rectangular rod is matched with the maximum sliding distance of the rotating rod 42 in the positioning cylinder 41 to ensure that the hollow shaft 44 is always limited by the rotating rod 42. The specific dimensions of the U-shaped hook 36 can be modified according to the actual situation to ensure that the lever 45 is not interfered with when it rotates along the axis of the support shaft 23.
[0032] Refer to the instruction manual appendix Figure 4 and Figure 8 In this embodiment, a spring 43 is provided inside the positioning cylinder 41. The spring 43 abuts against the rotating rod 42. Two sets of slots are provided on the positioning cylinder 41. The slots are used to fix the angle of the rotating rod 42 after rotation.
[0033] It should be noted that, through the cooperation of spring 43 and two sets of slots, the rotating rod 42 can automatically remain in the two states of unlocking and locking, which correspond to the installation of the plate body 51 and the installation of the plate body 51.
[0034] Refer to the instruction manual appendix Figure 1 and Figure 10 In this embodiment, two guide sleeves are provided on the column 21. A limit rod 37 is slidably provided on the guide sleeve. An L-shaped rod 38 is provided at the end of the limit rod 37 away from the corresponding support seat 31. A sliding frame 39 is provided at one end of the L-shaped rod 38. The sliding frame 39 is movably connected to the rotating rod 42.
[0035] It should be noted that by adjusting the position of the limit rod 37, the rotation of the support base 31 can be controlled, so that after the plate body 51 is installed, the support base 31 is locked and cannot rotate, thereby improving the installation stability of the plate body 51.
[0036] Refer to the instruction manual appendix Figure 1 and Figure 10 In this embodiment, the support base 31 includes a horn groove 311, which is connected to a limiting hole 312, and the limiting rod 37 is adapted to the corresponding limiting hole 312.
[0037] It should be noted that by setting the horn groove 311, it is easier for workers to perform the locking operation when resetting the support base 31, thereby further improving construction efficiency.
[0038] Refer to the instruction manual appendix Figure 7 and Figure 9 In this embodiment, a guide groove is provided on the support cylinder 32, and a guide strip is provided on the connecting rod 33, with the guide strip matching the guide groove.
[0039] It should be noted that the movable range of the connecting rod 33 along the length of the support cylinder 32 needs to be limited to ensure the stability of the plate body 51 after installation and to effectively ensure the verticality of the connecting rod 33.
[0040] Refer to the instruction manual appendix Figure 7 and Figure 8 In this embodiment, a connecting strip is provided on the side of the support base 31 away from the horizontal column 22, and a connecting groove is provided on the side of the wedge plate 35 close to the support base 31. The connecting strip is adapted to the connecting groove.
[0041] It should be noted that the sliding range of the wedge plate 35 within the support cylinder 32 needs to be limited. At the same time, the connection groove and connecting strip ensure that the wedge plate 35 cannot move along the length of the support cylinder 32, further improving the stability of the wedge plate 35 in use.
[0042] Refer to the instruction manual appendix Figure 5 and Figure 6 In this embodiment, two adjacent wedge plates 35 on the same column 21 are arranged symmetrically with respect to the axis of the corresponding positioning cylinder 41, and two adjacent L-shaped rods 38 on the same column 21 are arranged symmetrically with respect to the axis of the corresponding positioning cylinder 41.
[0043] It should be noted that, through the above settings, the limiting effect of the two back bolts 52 on the plate body 51 can be controlled simultaneously, thereby optimizing and reducing the overall structure and thus reducing the cost of use.
[0044] Refer to the instruction manual appendix Figure 10 In this embodiment, the back bolt buckle 52 is provided with an adjusting bolt 53, which is used to adjust the position of the plate body 51. It should be noted that by rotating the adjusting bolt 53, the height of the plate body 51 installed on the plug socket 34 can be adjusted, which makes it easier for the staff to make fine adjustments to the plate body 51, thereby further improving the installation accuracy.
[0045] In this embodiment, the specific implementation scenario is as follows: when the sliding lock of the panel body 51 towards the outer wall 1 is released by rotating the rotating rod 42, the lock between the limiting rod 37 and the support base 31 is also released simultaneously. At this time, after pushing the panel body 51 inward, the angle of the panel body 51 can be rotated. Therefore, the panel body 51 can be pulled out horizontally in a "cross" state with the surrounding panel bodies 51, so that the staff has enough operating space to grab the two sides of the panel body 51. At the same time, the angle of the panel body 51 can be adjusted by temporarily placing it under the panel body 51 during the removal process. This effectively reduces the operating difficulty for the staff and provides a certain support for the panel body 51 during the removal process, significantly reducing the risk of the panel body 51 slipping and being damaged, and further improving the recycling rate.
[0046] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
