Description

Technical Field

[0001] This invention relates to the field of building exterior wall decoration construction technology, specifically a method for dry-hanging stone on the walls of public buildings. Background Technology

[0002] Large-scale dry-hanging stone cladding is widely used in the exterior wall decoration of public buildings. Stone, with its clean appearance, substantial texture, and dignified style, is a key material for shaping the professional image and functionality of buildings. Existing stone installation techniques are mainly divided into wet-laying and dry-hanging methods.

[0003] Traditional wet-laying techniques use cement mortar or adhesives to directly bond stone to the substrate. Because individual stone panels on the exterior walls of public buildings are quite heavy, they are prone to hollowing, cracking, and even detachment under temperature changes, material aging, and wind loads. Detached stone can not only damage building fixtures but also endanger personal safety in densely populated public areas, potentially leading to public safety incidents.

[0004] While existing dry-hanging technology avoids the drawbacks of wet installation, the existing hanging system lacks a mechanical locking structure to prevent loosening of large stone materials. Under long-term vibration or temperature difference, the connectors are at risk of creeping and loosening, which cannot fully meet the stringent requirements of public buildings for zero risk of long-term detachment. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a construction method for dry-hanging stone cladding on the walls of public buildings that can be installed quickly and has strong stability.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A method for dry-hanging stone cladding on the walls of public buildings includes the following steps:

[0008] S1: The pre-supported back panel with positioning grooves is fixedly installed on the exterior wall of the main building structure.

[0009] S2: Provides a stone bracket. The upper and lower corners of the stone bracket are equipped with retractable grabs. The back of the stone bracket is equipped with a clip that is opposite to the positioning groove of the back plate and can be engaged. Adjust the retractable grab to the preset length and lock it through the anti-reverse device.

[0010] S3: Place the exterior wall stone between the retractable corner brackets. A soft sponge layer is pasted on the inside of the retractable corner brackets. Adjust the retractable corner brackets at the top and bottom of the exterior wall stone so that the retractable corner brackets at the top and bottom of the exterior wall stone clamp the exterior wall stone. When the retractable corner brackets clamp the exterior wall stone, the soft sponge layer is in a compressed and deformed state to ensure that the stone can be fixed firmly.

[0011] S4: Move the assembled exterior wall stone bracket to the back panel, aligning the clips on the back of the stone bracket with the positioning grooves on the back panel.

[0012] S5: Apply pressure to press the clips of the stone bracket into the positioning groove of the back plate until the clips of the stone bracket and the positioning groove are engaged and locked.

[0013] S6: Repeat steps S2-S5 and fill the joints between adjacent exterior wall stones with grout, so that the grout completely covers and wraps the ends of the retractable corner.

[0014] Furthermore, the retractable gripper is extended and retracted by rotating the adjustment knob to drive the internal gear mechanism; it can provide a relatively uniform and controllable extension stroke adjustment, which makes it easy for operators to make precise adjustments according to the actual size of the stone. At the same time, the gear mechanism has a self-locking characteristic, which helps to keep the gripper position stable after adjustment.

[0015] Furthermore, the anti-reverse device prevents the retractable clamp from retracting in the locked state; after the retractable clamp clamps the stone, it prevents the clamp from loosening and retracting due to vibration or external force, thereby maintaining a continuous clamping force on the stone and reducing the risk of the stone loosening during long-term use.

[0016] Furthermore, the back plate is made of high-strength aluminum alloy, and the opening of the positioning groove is provided with a guide chamfer; it provides guidance when the clip is inserted, reduces the difficulty of alignment, and reduces the possibility of the clip getting stuck on the edge of the groove during installation.

[0017] Furthermore, the engagement method between the clip and the positioning groove is an elastic press-type locking structure; when pressure is applied, it can quickly snap into place and form a stable lock after engagement. The installation process does not require additional tools or complicated operations. At the same time, this structure allows the lock to be released through a specific operation when needed, which is convenient for later maintenance or replacement of stone.

[0018] Furthermore, the grout is a weather-resistant sealant; it helps to resist ultraviolet rays, temperature changes and moisture erosion in the long term.

[0019] Furthermore, the back panel is fixed to the main building structure by anchor bolts; it has high tensile and shear bearing capacity, making it suitable for use in public building exterior walls and other occasions with high safety requirements.

[0020] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0021] The method described in this invention pre-fixes a back plate with positioning grooves to the main building structure and uses a stone bracket with retractable corner brackets and back clamps to clamp and lock the exterior wall stone. This effectively solves the problems of hollowing, cracking, and even falling off caused by the stone's own weight, temperature changes, and wind loads in traditional wet-laying processes. It also overcomes the shortcomings of existing dry-hanging systems, such as the lack of mechanical anti-loosening structures and the tendency of connectors to creep and loosen under long-term vibration or temperature differences. The retractable corner brackets are locked to a preset length by a backstop device, and when clamping the stone, the soft... The high-quality sponge layer is in a compressed and deformed state, which can adapt to stones of different sizes and provide stable clamping force. The elasticity of the sponge can also reduce stress concentration. The press-type locking of the clips and positioning grooves can achieve quick mechanical locking and anti-loosening effect, preventing the stone from shifting or falling off during long-term use. In addition, the grout completely covers and wraps the retractable corner ends, further enhancing the sealing of the joints and the overall stability. This meets the stringent requirements of public buildings for zero risk of long-term detachment, while improving installation efficiency and construction consistency. Attached Figure Description

[0028] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown in the figure, this embodiment provides a method for dry-hanging stone cladding on the walls of public buildings, including the following steps:

[0030] S1: The pre-supported back plate 3 with positioning grooves is fixedly installed on the outer wall of the main building structure 1.

[0031] S2: Provide a stone bracket 4. The upper and lower corners of the stone bracket 4 are respectively provided with retractable grab angles 41. The back of the stone bracket 4 is provided with a clip 43 that is opposite to the positioning groove of the back plate 3 and can be engaged. Adjust the retractable grab angles 41 to a preset length and lock them through the anti-reverse device 42.

[0032] S3: Place the exterior wall stone 5 between the retractable angle brackets 41. A soft sponge layer is pasted on the inside of the retractable angle brackets 41. Adjust the retractable angle brackets 41 at the top and bottom of the exterior wall stone 5 so that the retractable angle brackets 41 at the top and bottom of the exterior wall stone 5 clamp the exterior wall stone 5. When the retractable angle brackets 41 clamp the exterior wall stone 5, the soft sponge layer is in a compressed and deformed state to ensure that the stone can be fixed firmly.

[0033] S4: Move the assembled exterior wall stone 5 stone bracket 4 to the back plate 3, so that the clip 43 on the back of the stone bracket 4 is aligned with the positioning groove of the back plate 3.

[0034] S5: Apply pressure to press the clip 43 of the stone bracket 4 into the positioning groove of the back plate 3 until the clip 43 of the stone bracket 4 engages and locks with the positioning groove.

[0035] S6: Repeat steps S2-S5 and fill the joints between adjacent exterior wall stones 5 with grout so that the grout completely covers and wraps the ends of the retractable corner 41.

[0036] The retractable gripping angle 41 extends and retracts by rotating the adjustment knob to drive the internal gear mechanism; it can provide a relatively uniform and controllable extension stroke adjustment, which makes it easy for operators to make precise adjustments according to the actual size of the stone. At the same time, the gear mechanism has a self-locking characteristic, which helps to keep the gripping angle position stable after adjustment.

[0037] The anti-reverse device 42 prevents the retractable gripper 41 from retracting in the locked state; after the retractable gripper 41 clamps the stone, it prevents the gripper from loosening and retracting due to vibration or external force, thereby maintaining a continuous clamping force on the stone and reducing the risk of the stone loosening during long-term use.

[0038] The back plate 3 is made of high-strength aluminum alloy, and the opening of the positioning groove is provided with a guide chamfer; it provides guidance when the clip 43 is inserted, reduces the difficulty of alignment, and reduces the possibility of the clip 43 getting stuck with the edge of the groove during the installation process.

[0039] The engagement method between the clip 43 and the positioning groove is an elastic press-type locking structure; it can quickly snap into place when pressure is applied and form a stable lock after engagement. The installation process does not require additional tools or complicated operations. At the same time, the structure allows the lock to be released by a specific operation when needed, which is convenient for later maintenance or replacement of stone.

[0040] Grout is a weather-resistant sealant; it helps to resist ultraviolet rays, temperature changes and moisture erosion in the long term.

[0041] The back plate 3 is fixed to the main building structure 1 by anchor bolts 2; it has high tensile and shear bearing capacity and is suitable for use in public building exterior walls and other occasions with high safety requirements.

[0042] The method described in this invention pre-fixes the back plate 3 with positioning grooves to the main building structure 1, and uses a stone bracket 4 with retractable grab angles 41 and back clips 43 to clamp and lock the exterior wall stone 5. This effectively solves the problems of hollowing, cracking, and even falling off caused by the weight of the stone, temperature changes, and wind loads in traditional wet-laying processes. At the same time, it overcomes the shortcomings of existing dry-hanging systems, such as the lack of mechanical anti-loosening structures and the easy creep and loosening of connectors under long-term vibration or temperature difference. The retractable grab angles 41 are locked to a preset length by the anti-reverse device 42, and the clamping stone... The material is designed to keep the soft sponge layer in a compressed and deformed state, which can adapt to stones of different sizes, provide stable clamping force, and reduce stress concentration through the elasticity of the sponge. The press-type locking of the clip 43 and the positioning groove achieves a quick mechanical locking and anti-loosening effect, preventing the stone from shifting or falling off during long-term use. In addition, the grout completely covers and wraps the end of the retractable corner 41, further enhancing the sealing and overall stability of the joint, thereby meeting the stringent requirements of public buildings for long-term zero risk of falling off, while improving installation efficiency and construction consistency.

[0043] The above description is merely a preferred embodiment of the present invention and does not limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
