Description

Technical Field

[0001] This utility model relates to the field of stone hanging accessories, and in particular to a three-dimensional adjustable stone hanging accessory. Background Technology

[0002] Dry-hanging stone cladding, also known as air-hanging, is a new construction technique in wall decoration. This method involves directly suspending the cladding stone from the wall or onto a steel frame using metal hangers, without the need for grouting or adhesive. The principle is to establish main load-bearing points on the main structure and then fix the stone to the building using metal stone hangers, forming a stone decorative curtain wall.

[0003] During the installation of stone decorative curtain walls, stone hangers need to be adjusted to ensure the flatness of each stone slab, thereby guaranteeing the aesthetics of the stone decorative curtain wall. Currently, most stone hangers, when fixing stone slabs, can only adjust one of the following positions: vertical, front-back, or horizontal. This adjustment is inconvenient and reduces the work efficiency of the staff. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a three-dimensional adjustable stone pendant.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a three-dimensional adjustable stone pendant, including a lower connector and an L-shaped plate connected to an angle iron. A first oblong hole is provided on the horizontal section of the L-shaped plate. A screw passes through the first oblong hole and is screwed into the fixing hole of the angle iron to fix the L-shaped plate. The length direction of the first oblong hole is consistent with the length direction of the angle iron. A square block is horizontally arranged on the vertical section of the L-shaped plate. A threaded hole is horizontally provided on the square block. The lower part of the lower connector is connected to the upper part of the stone plate. A second oblong hole is vertically arranged on the upper part of the lower connector. A fixing bolt is provided in the second oblong hole. A fixing nut is provided on the fixing bolt. The end of the fixing bolt is screwed into the threaded hole.

[0006] By adopting the above technical solution, an L-shaped plate, a square block, a lower connector, a fixing bolt, and a fixing nut are set up. When the stone slab needs to be fixed, first, the screw is passed through the first oblong hole and screwed into the fixing hole of the angle iron. At this time, the screw does not need to be tightened. Then, the fixing nut is unscrewed. After that, the fixing bolt is passed through the second oblong hole, and the fixing nut is screwed back onto the fixing nut. At this time, the fixing nut does not need to be tightened. Then, the fixing bolt is screwed into the threaded hole. Due to the setting of the first oblong hole, the L-shaped plate can move left and right, so that the left and right position of the stone slab can be adjusted. After the left and right position of the stone slab is adjusted, the screw is tightened to fix the L-shaped plate. Due to the setting of the second oblong hole, the up and down position of the stone slab can be adjusted. By turning the fixing bolt, the front and back position of the stone slab can be adjusted. After the up and down and front and back positions of the stone slab are accurately adjusted, the fixing nut is tightened onto the head of the fixing bolt, so that the head of the fixing bolt locks the lower connector with the fixing bolt, thereby completing the fixing of the stone slab. When fixing stone slabs, the stone hanger can be adjusted in terms of vertical, front-back, and left-right positions, and the adjustment is convenient, which improves the work efficiency of the staff.

[0007] Furthermore, the lower connector includes a first fixing plate connected to the upper part of the stone slab. A first connecting plate is horizontally arranged on the first fixing plate, and a vertical plate is vertically arranged on the first connecting plate. A second oblong hole is opened on the vertical plate. A fixing ring is sleeved on the head of the fixing bolt. The thickness of the fixing ring is consistent with the distance from the vertical plate to the stone slab.

[0008] By adopting the above technical solution, a first fixing plate, a first connecting plate, a vertical plate, and a fixing ring are set up so that after the stone slab is fixed, its inner side plate surface contacts the fixing ring, thereby enhancing the fixing effect on the stone slab.

[0009] Furthermore, an upper connector is provided above the lower connector. The upper connector includes a second fixing plate connected to the lower part of the stone slab. A second connecting plate is horizontally provided on the second fixing plate. A locking plate is provided at the bottom of the second connecting plate away from the second fixing plate. A locking groove is provided at the bottom of the locking plate to cooperate with the square block. Fixing blocks are provided on both sides of the square block. The distance from the side of the locking plate adjacent to the stone slab to the stone slab is the same as the distance from the side of the fixing block away from the stone slab to the stone slab.

[0010] By adopting the above technical solution, a second fixing plate, a second connecting plate, a clamping plate, a clamping groove, and a fixing block are set up. When fixing the stone slab, the clamping plate is first inserted between the fixing block and the L-shaped plate, so that the clamping groove cooperates with the square block. Since the distance from the side of the clamping plate near the stone slab to the stone slab is the same as the distance from the side of the fixing block away from the stone slab to the stone slab, the clamping plate contacts the fixing block, and the clamping plate cooperates with the fixing ring, further increasing the fixing effect on the stone slab.

[0011] Furthermore, a wedge-shaped block is provided on the top of both fixing blocks and the square block, and the lower edge of the inclined surface of the wedge-shaped block contacts the top edge of the side of the fixing block away from the stone slab.

[0012] By adopting the above technical solution, a wedge-shaped block is set together on the top of the two fixed blocks and the square block, which makes it easy for the lower part of the card plate to slide into the space between the fixed block and the L-shaped plate.

[0013] Furthermore, the distance from the fixing block to the L-shaped plate is consistent with the thickness of the card plate.

[0014] By adopting the above technical solution, the distance between the fixing block and the L-shaped plate is set to be consistent with the thickness of the clamping plate, so that the clamping plate can be clamped between the fixing block and the L-shaped plate, thereby increasing the stability of the clamping plate.

[0015] Furthermore, an upper connecting bolt is provided on the upper part of the inner side panel of the stone slab, a first through hole is provided on the first fixing plate, and an upper connecting nut is spirally provided on the upper connecting bolt.

[0016] By adopting the above technical solution, an upper connecting bolt and an upper connecting nut are set. First, the upper connecting nut is unscrewed from the upper connecting bolt. Then, the first fixing plate is moved so that the upper connecting bolt passes through the first through hole. Then, the upper connecting bolt is screwed onto the upper connecting bolt to fix the first fixing plate, thereby making the lower connecting piece stably connected to the stone slab.

[0017] Furthermore, a lower connecting bolt is provided on the upper part of the inner side panel of the stone slab, a second through hole is provided on the second fixing plate, and a lower connecting nut is spirally provided on the lower connecting bolt.

[0018] By adopting the above technical solution, a lower connecting bolt and a lower connecting nut are set. First, the lower connecting nut is unscrewed from the lower connecting bolt. Then, the second fixing plate is moved so that the lower connecting bolt passes through the second through hole. The lower connecting bolt is then screwed onto the lower connecting bolt to fix the second fixing plate, thereby making the upper connecting part stably connected to the stone slab.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, an L-shaped plate, a square block, a lower connector, a fixing bolt, and a fixing nut are provided. When fixing the stone slab, first, the screw is passed through the first oblong hole and screwed into the fixing hole of the angle iron. At this time, the screw does not need to be tightened. Then, the fixing nut is unscrewed. After that, the fixing bolt is passed through the second oblong hole, and the fixing nut is screwed back onto the fixing nut. At this time, the fixing nut does not need to be tightened. Then, the fixing bolt is screwed into the threaded hole. Due to the setting of the first oblong hole, the L-shaped plate can move left and right, so that the left and right position of the stone slab can be adjusted. After the left and right position of the stone slab is adjusted, the screw is tightened to fix the L-shaped plate. Due to the setting of the second oblong hole, the up and down position of the stone slab can be adjusted. By turning the fixing bolt, the front and back position of the stone slab can be adjusted. After the up and down and front and back positions of the stone slab are accurately adjusted, the fixing nut is tightened onto the head of the fixing bolt, so that the head of the fixing bolt and the fixing bolt lock the lower connector, thereby completing the fixing of the stone slab. When fixing stone slabs, the vertical, front-back, and left-right positions of the stone slabs can be adjusted, and the adjustment is convenient, which improves the work efficiency of the staff.

[0021] 2. In this application, a second fixing plate, a second connecting plate, a clamping plate, a clamping groove, and a fixing block are provided. When fixing the stone slab, the clamping plate is first inserted between the fixing block and the L-shaped plate, so that the clamping groove cooperates with the square block. Since the distance from the side of the clamping plate near the stone slab to the stone slab is the same as the distance from the side of the fixing block away from the stone slab to the stone slab, the clamping plate contacts the fixing block, and the clamping plate cooperates with the fixing ring, further increasing the fixing effect on the stone slab.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] like Figure 1-7 As shown in the illustration, this application discloses a three-dimensional adjustable stone hanger, including an L-shaped plate 30, a lower connector 10, and an upper connector 50. Several horizontally arranged angle irons 1 are vertically spaced on the wall, and the angle irons 1 can be connected to the wall using chemical bolts. The stone hanger has several angle irons 1. The lower connector 10 connects to the upper part of the lower stone slab of the hanger, and the upper connector 50 connects to the lower part of the upper stone slab of the hanger, thereby fixing the stone slab. The workers install the stone slab from bottom to top.

[0032] Specifically, the L-shaped plate 30 is used to connect with the angle iron 1. A first oblong hole 31 is provided on the horizontal section of the L-shaped plate 30. Several fixing holes are provided on the angle iron 1. The fixing holes are screw holes. The screw passes through the first oblong hole 31 and is screwed into the fixing hole of the angle iron 1 to fix the L-shaped plate 30. The fixing hole can also be a round hole. After the screw passes through the first oblong hole 31 and the fixing hole, it is connected to the nut to fix the L-shaped plate 30. The length direction of the first oblong hole 31 is consistent with the length direction of the angle iron 1. A square block 32 is horizontally provided on the vertical section of the L-shaped plate 30. A threaded hole 33 is horizontally provided on the square block 32. The lower part of the lower connector 10 is connected to the upper part of the stone slab. A second oblong hole 11 is vertically arranged on the upper part of the lower connector 10. A fixing bolt 20 is provided in the second oblong hole 11. The fixing bolt 20 can move freely. A fixing nut 21 is provided on the fixing bolt 20. The end of the fixing bolt 20 is screwed into the threaded hole 33. When fixing the stone slab, first pass the screw through the first oblong hole 31 and screw it into the fixing hole of the angle iron 1. At this time, the screw does not need to be tightened. Then unscrew the fixing nut 21. After that, pass the fixing bolt 20 through the second oblong hole 11 and screw the fixing nut 21 back onto the fixing nut 21. At this time, the fixing nut 21 does not need to be tightened. Then screw the fixing bolt 20 into the threaded hole 33. Due to the setting of the first oblong hole 31, the L-shaped plate 30 can move left and right, thereby allowing the stone slab to move left and right. The position is adjustable. After adjusting the left and right positions of the stone slab, tighten the screws to fix the L-shaped plate 30. Due to the setting of the second oblong hole 11, the vertical position of the stone slab can be adjusted. Tightening the fixing bolt 20 can adjust the front and back positions of the stone slab. After the vertical, horizontal, and back positions of the stone slab are accurately adjusted, tighten the fixing nut 21 onto the head of the fixing bolt 20, so that the head of the fixing bolt 20 locks the lower connecting piece 10 with the fixing bolt 20, thereby completing the fixing of the stone slab. When fixing the stone slab, this stone hanger can adjust the vertical, front and back, and left and right positions of the stone slab, and the adjustment is convenient, improving the work efficiency of the staff.

[0033] During installation, the lower connector 10 includes a first fixing plate 12 connected to the upper part of the stone slab. A first connecting plate 13 is horizontally mounted on the first fixing plate 12, and a vertical plate 14 is vertically mounted on the first connecting plate 13. A second oblong hole 11 is formed on the vertical plate 14. An upper connecting bolt 70 is provided on the upper part of the inner side surface of the stone slab. A first through hole 71 is formed on the first fixing plate 12, and an upper connecting nut 72 is screwed onto the upper connecting bolt 70. First, the upper connecting nut 72 is unscrewed from the upper connecting bolt 70. Then, the first fixing plate 12 is moved so that the upper connecting bolt 70 passes through the first through hole 71. The upper connecting bolt 70 is then screwed onto the upper connecting bolt 70 to fix the first fixing plate 12, thereby ensuring a stable connection between the lower connector 10 and the stone slab. The upper connecting bolt 70 is an expansion bolt. A hole is first drilled in the upper part of the stone slab, and then the upper connecting bolt 70 is installed in the hole.

[0034] An upper connector 50 is provided above the lower connector 10. The upper connector 50 includes a second fixing plate 51 connected to the lower part of the stone slab. A second connecting plate 52 is horizontally arranged on the second fixing plate 51, and a retaining plate 53 is provided at the bottom of the second connecting plate 52 away from the second fixing plate 51. A lower connecting bolt 80 is provided on the upper part of the inner side surface of the stone slab. A second through hole 81 is opened on the second fixing plate 51. A lower connecting nut 82 is screwed onto the lower connecting bolt 80. First, the lower connecting nut 82 is unscrewed from the lower connecting bolt 80. Then, the second fixing plate 51 is moved so that the lower connecting bolt 80 passes through the second through hole 81. Then, the lower connecting bolt 80 is screwed onto the lower connecting bolt 80 to fix the second fixing plate 51, thereby making the upper connector 50 stably connected to the stone slab. The lower connecting bolt 80 is an expansion bolt. First, a hole is opened in the upper part of the stone slab, and then the lower connecting bolt 80 is installed in the hole.

[0035] In the specific setup, a fixing ring 40 is fitted onto the head of the fixing bolt 20. The thickness of the fixing ring 40 is consistent with the distance between the upright plate 14 and the stone slab, so that after the stone slab is fixed, its inner surface contacts the fixing ring 40, enhancing the fixing effect on the stone slab. A slot 54 is provided at the lower part of the clamping plate 53 to mate with the square block 32. Fixing blocks 60 are provided on both sides of the square block 32. The distance from the side of the clamping plate 53 adjacent to the stone slab to the stone slab is consistent with the distance from the side of the fixing block 60 away from the stone slab to the stone slab. When fixing the stone slab, the clamping plate 53 is first inserted between the fixing block 60 and the L-shaped plate 30, so that the slot 54 mates with the square block 32. Since the distance from the side of the clamping plate 53 adjacent to the stone slab to the stone slab is consistent with the distance from the side of the fixing block 60 away from the stone slab to the stone slab, the clamping plate 53 contacts the fixing block 60, and the clamping plate 53 mates with the fixing ring 40, further increasing the fixing effect on the stone slab.

[0036] The distance between the fixing block 60 and the L-shaped plate 30 is the same as the thickness of the clamping plate 53, allowing the clamping plate 53 to be secured between the fixing block 60 and the L-shaped plate 30, increasing the stability of the clamping plate 53. A wedge-shaped block 61 is provided on the top of both fixing blocks 60 and the square block 32. The lower edge of the inclined surface of the wedge-shaped block 61 contacts the top edge of the side of the fixing block 60 away from the stone slab, facilitating the lower part of the clamping plate 53 to slide between the fixing block 60 and the L-shaped plate 30.

[0037] The working principle of a three-dimensional adjustable stone hanger in this embodiment is as follows: When it is necessary to fix the stone slab on the lower side of the stone hanger, first, pass the screw through the first oblong hole 31 and screw it into the fixing hole of the angle iron 1. At this time, the screw does not need to be tightened. Then, unscrew the fixing nut 21, and then pass the fixing bolt 20 through the second oblong hole 11. Then, screw the fixing nut 21 back onto the fixing nut 21. At this time, it is also not necessary to tighten the fixing nut 21. Then, screw the fixing bolt 20 into the threaded hole 33. After moving the L-shaped plate 30 to adjust the left and right position of the stone slab, tighten the screw to fix the L-shaped plate 30. Due to the setting of the second oblong hole 11, the vertical position of the stone slab is adjusted. Adjustment is possible by turning the fixing bolt 20 to adjust the front and back position of the stone slab. After the stone slab is accurately adjusted in terms of its vertical and horizontal position, tighten the fixing nut 21 onto the head of the fixing bolt 20, so that the head of the fixing bolt 20 locks the lower connecting piece 10 with the fixing bolt 20, thereby completing the fixing of the stone slab on the lower side of the stone hanger. Then, connect the upper connecting piece 50 to the upper stone slab of the stone hanger. When installing the upper stone slab of the stone hanger, the worker moves the stone slab so that the clamping plate 53 is inserted between the fixing block 60 and the L-shaped plate 30. The clamping plate 53 cooperates with the fixing ring 40 to fix the lower part of the upper stone slab of the stone hanger.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
