Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and more specifically to a device for replacing stone curtain wall panels. Background Technology

[0002] In stone curtain wall projects, the joint width is typically 6-8mm, which is usually less than the insertion depth of the hangers. This makes it difficult to remove the bolts of the rear hangers without damaging the panel. Currently common post-installation methods are not ideal: one is to use stainless steel L-shaped hangers, but this requires partial cutting of the stone mounting edge and relies entirely on epoxy resin adhesive for bonding and fixing. The long-term safety of the stone depends solely on the durability of the adhesive, posing a safety hazard of aging and detachment; another method is to use "angled inserts + epoxy resin adhesive," but angled inserts themselves have been explicitly prohibited and phased out by industry standards, making them unfeasible in terms of compliance.

[0021] Existing methods for replacing stone curtain wall panels rely on epoxy resin adhesive for fixation, posing significant safety hazards. To address this issue, the basic idea of ​​this invention is to create a snap-fit ​​connection between an aluminum alloy profile and the upper row of aluminum alloy mounting brackets, allowing the stone to be rotated during installation. This reduces damage to surrounding stone, minimizes operating space, reduces installation errors, and improves safety.

[0022] refer to Figures 1 to 15 This utility model discloses a stone curtain wall panel replacement device, including a main keel 1 and a secondary keel 2 fixedly connected to the main keel 1. The secondary keel 2 includes a first keel 21 and a second keel 22. An upper row of aluminum alloy hanger bases 4 are fixed on the first keel 21, and a lower row of aluminum alloy hanger bases 7 are fixed on the second keel 22. A 2mm thick EPDM hard pad 5 is added between the upper and lower row of aluminum alloy hanger bases 4 and 7 and the secondary keel 2. The upper and lower row of aluminum alloy hanger bases 4 and 7 are fastened to the secondary keel 2 using a stainless steel bolt assembly 6. An aluminum alloy serrated limit adjustment block 3 is installed between the stainless steel bolt assembly 6 and the upper and lower row of aluminum alloy hanger bases 4 and 7. The stone curtain wall panel replacement device also includes... The first aluminum alloy hanger 9 is housed in the lower row of aluminum alloy hanger base 7. The first aluminum alloy hanger 9 can be inserted into the lower row of aluminum alloy hanger base 7 to achieve the connection between the first aluminum alloy hanger 9 and the lower row of aluminum alloy hanger base 7. A through hole can also be opened at the top of the first aluminum alloy hanger 9. Tightening the adjusting screw 8 can make it abut against the lower row of aluminum alloy hanger base 7, thereby achieving relative stillness between the first aluminum alloy hanger 9 and the lower row of aluminum alloy hanger base 7. The elevation of the stone 19 can be adjusted by adjusting the adjusting screw 8. The position of the second aluminum alloy hanger 12 is set according to the corresponding position of the lower row aluminum alloy hanger base 7 on the second keel 22. Generally speaking, two lower row aluminum alloy hanger bases 7 are set and evenly located in the middle of the second keel 22 so that the force is evenly distributed. The second aluminum alloy hanger 12 should also be set in the corresponding position of the lower row aluminum alloy hanger base 7, otherwise the two will be difficult to match. The second aluminum alloy bracket 12 can be fixedly connected to the stone 19, such as by using a back bolt 11 to firmly connect the second aluminum alloy bracket 12 to the stone 19, preferably using a stainless steel back bolt; The second aluminum alloy hanger 12 is hinged to the first aluminum alloy hanger 9. The second aluminum alloy hanger 12 can rotate relative to the first aluminum alloy hanger 9. That is, the second aluminum alloy hanger 12 can rotate around the hinge axis of the two. Correspondingly, the stone 19 also rotates around the hinge axis. The third aluminum alloy hanger 14 is positioned according to the corresponding position of the upper row aluminum alloy hanger base 4 on the first keel 21. It can be seen that there are two upper row aluminum alloy hanger bases 4, which are evenly located in the middle of the first keel 21 to ensure that the force is evenly distributed. The third aluminum alloy hanger 14 should also be positioned in the corresponding position of the upper row aluminum alloy hanger base 4, otherwise the two will be difficult to match. The third aluminum alloy bracket 14 can be fixedly connected to the stone 19, such as by using a back bolt 11 to firmly connect the third aluminum alloy bracket 14 to the stone 19, preferably using a stainless steel back bolt. The third aluminum alloy bracket 14 houses the aluminum alloy profile 15. When the second aluminum alloy bracket 12 rotates 90 degrees relative to the first aluminum alloy bracket 9, the aluminum alloy profile 15 can be engaged with the upper row of aluminum alloy bracket bases 4, thereby achieving the effect of rotating the stone, reducing damage to the surrounding stone, reducing operating space, and minimizing installation errors.

[0023] Specifically, at least one side of the aluminum alloy profile 15 is provided with a stop portion 151. The aluminum alloy profile 15 is placed into the cavity of the third aluminum alloy hanger 14 from the side. When the third aluminum alloy hanger 14 is in a vertical position, the aluminum alloy material 15 is provided with a stop portion 151, so that it will not fall off the bottom of the third aluminum alloy hanger 14.

[0024] Preferably, both sides of the aluminum alloy profile 15 are provided with a stop portion 151, which is strip-shaped, so that its movement within the third aluminum alloy hanger 14 is more balanced and does not tilt or other phenomena.

[0025] In some embodiments, the upper opening of the third aluminum alloy hanger 14 is provided with a hole, and a spring nail 17 is provided at a position corresponding to the hole. The spring nail 17 can pass through the hole and abut against the top surface of the aluminum alloy profile 15. The bottom surface of the aluminum alloy profile 15 is constructed into a wedge shape to facilitate effective engagement with the upper row of aluminum alloy hanger bases 4. After engagement, the spring nail 17 can hold the top surface of the aluminum alloy profile 15, so that the two are firmly connected and not easily loosened.

[0026] It should be noted that a groove can also be constructed at the upper opening of the third aluminum alloy pendant 14, which can accommodate a metal card 16. The metal card 16 has a through hole, the size of which matches the size of the hole in the third aluminum alloy pendant 14. The spring on the spring nail 17 is fixedly connected to the metal card 16, such as by welding or other connection methods. Pulling the spring nail 17 can place the metal card 16 into the groove. When the through hole on the metal card 16 corresponds to the hole on the third aluminum alloy pendant 14, the spring nail 17 is released, and the nail head enters the cavity of the third aluminum alloy pendant 14.

[0027] The top of the spring nail 17 is connected to a traction rope 18. Pulling or releasing the traction rope 18 can move the spring nail 17 away from or close to the top surface of the aluminum alloy profile 15, making it easier for the aluminum alloy profile 15 to engage with the upper row of aluminum alloy hanging base 4. After engagement, the traction rope can be cut through the gap between the stones and dropped directly into the interior of the stone.

[0028] In some embodiments, the second aluminum alloy bracket 12 and the first aluminum alloy bracket 9 are hinged together by a stainless steel shaft 13. That is, the stainless steel shaft 13 passes through the connecting hole of the first aluminum alloy bracket 9 and the connecting hole of the second aluminum alloy bracket 12.

[0029] Preferably, a small hole is formed at the end of the stainless steel shaft 13, and an iron wire 10 in a bow shape is inserted into the small hole. The two ends of the iron wire 10 are bent to fix the stainless steel shaft 13 and prevent it from coming out.

[0030] The basic steps of this method for replacing stone curtain wall panels are as follows: The upper row of aluminum alloy hanger base 4 is fixedly connected to the first keel 21, and the lower row of aluminum alloy hanger base 7 is fixedly connected to the second keel 22. The first aluminum alloy hanger 9 is hinged to the second aluminum alloy hanger 12, the second aluminum alloy hanger 12 is fixedly connected to the stone 19, and the third aluminum alloy hanger 14 is fixedly connected to the stone 19. Insert the aluminum alloy profile 15 into the third aluminum alloy bracket 14; Rotate the second aluminum alloy bracket by 90 degrees to engage the aluminum alloy profile 15 with the upper row of aluminum alloy bracket base 4.

[0031] In some embodiments, it is necessary to first set up a barrier, remove the damaged stone and its aluminum alloy stone hanging parts to prevent fragments from falling; after installation, use a level to calibrate the flatness and verticality of the stone to ensure that the gap width is consistent; clean the dust layer in the gap, fill it with foam rods, and apply silicone weather-resistant sealant.

[0032] Specifically, the upper and lower rows of aluminum alloy hanger bases are fastened to the secondary keel with stainless steel bolts; according to the site positioning, holes are drilled on the back of the stone, and the second and third aluminum alloy hangers are fixedly connected to the stone with stainless steel back bolts. The first and second aluminum alloy hangers are hinged by a stainless steel shaft. The stone is rotated around the stainless steel shaft, and the stainless steel spring nail is pulled by a traction rope, so that the aluminum alloy profile and the upper row of aluminum alloy hanger bases are interlocked.

[0033] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. If any person skilled in the art, inspired by this description, designs a similar structure to the present invention without departing from its inventive spirit, such design shall fall within the protection scope of the present invention.
