Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and in particular to a curtain wall stone hanging component connection structure and its construction process. Background Technology

[0002] Due to its advantages such as convenient construction, excellent surface effect, and minimal impact on the load of the main building structure, the dry-hanging stone process has become the mainstream construction method for modern building curtain wall stone decoration. Its core relies on the stone hanging component connection structure to achieve reliable fixing of the stone and the building keel. The stability, anti-slip properties, and construction adaptability of the connection structure directly determine the construction quality and safety of the curtain wall project.

[0003] Currently, most curtain wall stone cladding connection structures use conventional bolts with aluminum alloy brackets. However, this technology reveals several drawbacks during actual construction and use: First, the main bracket and stone bracket are connected by bolts and anti-slip pads. Incorrect placement of the anti-slip pads during construction can lead to a lack of anti-slip effect. When the stone is subjected to impact, vibration, or temperature deformation, slippage can occur, reducing the overall stability of the curtain wall connection and posing safety hazards. Second, errors are prone to occur during on-site layout. The fixed overlap dimensions and positions of traditional brackets cannot effectively compensate for these errors, resulting in insufficient overlap lengths or height differences between the main bracket and the stone bracket, requiring on-site adjustments. This not only increases construction steps but also affects construction accuracy. Third, the locking and adjustment of traditional bracket connections rely heavily on specialized tools such as wrenches and screwdrivers. Insufficient tool availability or poor tool compatibility during construction can directly lead to delays in construction procedures and project timelines.

[0004] To address the technical problems of existing curtain wall stone cladding connection structures, such as poor anti-slip properties, inability to compensate for on-site layout errors, reliance on specialized tools, and low efficiency, there is an urgent need to develop a curtain wall stone cladding connection structure that offers stable connections, excellent anti-slip performance, adaptability to on-site construction errors, and tool-free rapid operation. Furthermore, it is essential to develop a corresponding efficient construction process to compensate for the shortcomings of existing technologies and improve the construction quality, efficiency, and safety of dry-hanging curtain wall stone projects.

[0005] How to solve the above-mentioned technical problems is the challenge facing this invention. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a reasonably designed, safe, and reliable curtain wall stone hanging component connection structure and its construction process. Through the interlocking of the anti-slip structure, the potential for slippage is fundamentally eliminated, ensuring high anti-slip reliability. The elongated hole design effectively absorbs construction errors, guaranteeing connection quality. The manual locking components greatly improve installation efficiency and convenience. The overall system is highly integrated, significantly improving the construction quality, efficiency, and safety of curtain wall projects.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a curtain wall stone hanging component connection structure, including a vertical bearing base, fixed to the building keel; The L-shaped connection assembly includes a horizontal overlap portion that matches the vertical bearing base, and a vertical connection portion disposed at one end of the horizontal overlap portion; and the vertical connection portion is provided with an elongated adjustment hole extending along its length direction, and an adjustment screw unit for connecting with the curtain wall stone is disposed in the elongated adjustment hole. The locking cap covers the horizontal overlap of the L-shaped connecting assembly; The locking assembly is sequentially connected to the locking cover, the horizontal overlapping part of the L-shaped connecting assembly, and the vertical bearing base, and the three are pressed and fixed together; the locking assembly is provided with an integrally formed operating part for the operator to drive by hand. The top surface of the vertical bearing base, the top and bottom surfaces of the horizontal overlapping part, and the bottom surface of the locking cover are all provided with mutually compatible anti-slip structures.

[0008] Furthermore, the anti-slip structure includes a series of parallel anti-slip ripples with a continuous sinusoidal wave pattern on the top surface of the vertical bearing base, the top and bottom surfaces of the horizontal overlap, and the bottom surface of the locking cover.

[0009] Preferably, one or two elastic rubber strips are embedded in the top and / or bottom surface of the horizontal overlapping portion of the L-shaped connecting component, and the surface of the rubber strips is provided with micro-protrusions.

[0010] Furthermore, the locking assembly includes two sets of locking units symmetrically arranged on the vertical support base, each set of locking units including two locking units respectively arranged on both sides of the horizontal overlap; and the vertical support base and the locking cover are provided with locking screw grooves that cooperate with the locking units; The locking assembly includes a locking screw that passes through the locking screw groove, and one end of the locking screw is provided with an adjustment handle for constituting the operating part.

[0011] The adjusting handle is configured as a foldable T-shaped handle hinged to the head of the locking screw, and the locking screw is provided with fasteners.

[0012] The fastener is configured as a fastening nut or a fastening pin.

[0013] In the above-mentioned screw structure, the screw is provided with a washer and an anti-slip washer that cooperate with the locking nut or fastening nut or wing nut.

[0014] Preferably, the vertical connecting part is fixedly connected to the stone curtain wall by back bolts, washers and nuts, with the back bolts passing through the elongated adjustment holes.

[0015] The adjusting screw unit includes a back bolt screw fixed to the stone, and the back bolt screw is provided with a back bolt nut, a back bolt washer and an anti-loosening washer.

[0016] Furthermore, the adjusting screw unit is equipped with a joint adjusting component for controlling the gap between two adjacent curtain wall stones.

[0017] The seam adjusting assembly includes a circular patch with a circular groove that mates with the back bolt screw. The circular patch has a first strip and a second strip, which are perpendicular to each other. Both the first strip and the second strip have seam control blocks.

[0018] Preferably, the seam control block has a groove that mates with the first or second adhesive strip, and the seam control block is provided with a seam control screw.

[0019] A method for constructing curtain wall stone, characterized by comprising the following steps: S1. Fix the vertical bearing base to the building keel; S2. Connect the L-shaped connecting component to the back bolt pre-installed on the back of the stone through the elongated adjustment hole of its vertical connecting part, and adjust the position of the L-shaped connecting component relative to the stone along the elongated adjustment hole; S3. Place the horizontal overlapping part of the L-shaped connecting component with stone connected in step S2 on the top surface of the vertical bearing base, so that the anti-slip structure provided on the top surface of the vertical bearing base and the bottom surface of the horizontal overlapping part makes initial contact. S4. Cover the top surface of the horizontal overlap with the locking cap, so that the anti-slip structure on the bottom surface of the locking cap initially contacts the anti-slip structure on the top surface of the horizontal overlap. S5. By manually operating the operating part of the locking assembly, the locking assembly is driven to connect and press the locking cover, the horizontal overlapping part and the vertical bearing base in sequence until the anti-slip structures on each component interlock, thus completing the installation of a single stone piece.

[0020] Furthermore, after step S2 and before step S3, step S2a is also included: installing the joint adjustment component on the back bolt on the back of the stone. The joint adjustment component includes a strip with a joint control block; after the installation of a single stone is completed, the component further includes step S5a: fitting the joint control block against the sidewall of the adjacent installed stone to control the width of the gap between the stones.

[0021] Furthermore, after step S5, step S6 is also included: checking whether the anti-slip structure of the vertical bearing base, the horizontal overlapping part and the locking cover is tightly engaged, and the locking status of the locking assembly.

[0022] This invention integrates mutually compatible anti-slip structures on the bottom surfaces of the vertical bearing base, the horizontal overlap of the L-shaped connecting component, and the locking cap, forming a "sandwich"-like multi-dimensional interlocking under the pressure of the locking component. This design transforms the anti-slip function from an error-prone additional pad into the component's own structure, completely eliminating the possibility of incorrect installation and failure of the anti-slip element. A rigid mechanical interlock is formed between the interlocking surfaces, providing anti-slip capability far exceeding traditional friction anti-slip methods, significantly enhancing the stability and safety of the connection node under dynamic loads.

[0023] The L-shaped connecting component of this invention features elongated adjustment holes in its vertical connecting portion, allowing for stepless vertical position adjustment when connected to stone. This design endows the structure with strong error absorption capabilities, effectively compensating for errors generated during the initial installation of the keel, layout, and stone processing. It ensures effective and sufficient overlap between the hangers under any working conditions, avoiding secondary on-site processing and guaranteeing a high first-time installation success rate and final connection strength.

[0024] This invention employs a locking assembly with an integrated operating unit. Construction workers do not need to carry or operate external wrenches or other specialized tools; they can complete the final locking operation entirely by hand. This not only simplifies the process, reduces tool management costs and the risk of tools falling, but also significantly improves the convenience and efficiency of high-altitude operations, making it particularly suitable for projects with tight schedules or limited operating space.

[0025] This invention provides a physical benchmark for flatness and a rigid limit for gap width in stone installation through an optional joint adjustment component. Construction workers can simultaneously control installation quality through intuitive observation and simple operation, reducing over-reliance on personal experience. This makes controlling the flatness and gap uniformity of the curtain wall simple, standardized, and reliable, effectively improving the overall aesthetics of the finish. Attached Figure Description

Detailed Implementation

[0032] See Figures 1 to 5 As shown, a curtain wall stone hanging component connection structure includes a vertical bearing base 100, which is fixed to the building keel 900; The L-shaped connecting assembly 200 includes a horizontal overlapping portion 210 that matches the vertical bearing base 100, and a vertical connecting portion 220 located at one end of the horizontal overlapping portion 210. The vertical connecting portion 220 is provided with an elongated adjustment hole 230 extending along its length direction. An adjustment screw unit 300 for connecting with the curtain wall stone is provided in the elongated adjustment hole 230. The length margin of the elongated adjustment hole 230 is used to absorb and compensate for unavoidable errors in layout, keel installation, or stone processing during on-site construction, thereby ensuring that accurate and reliable overlapping of the hangers can still be achieved even when errors exist.

[0033] A locking cap 400 covers the horizontal overlap portion 210 of the L-shaped connecting assembly; The locking assembly 500 is sequentially connected to the locking cap 400, the horizontal overlapping part 210 of the L-shaped connecting assembly 200, and the vertical bearing base 100, and the three are pressed and fixed together. The locking assembly 500 is provided with an integrally formed operating part for the operator to drive by hand. It abandons the traditional bolt connection mode that must rely on external wrenches and other special tools. Its manual operation significantly improves the convenience and safety of high-altitude operations and reduces tool management costs and operating threshold.

[0034] The top surface of the vertical bearing base 100, the top and bottom surfaces of the horizontal overlapping portion 210, and the bottom surface of the locking cap 400 are all equipped with mutually compatible anti-slip structures 600. Under the immense normal clamping force provided by the locking assembly 500, they interlock, and the anti-slip mechanism transitions from traditional static friction anti-slip to structural interlocking anti-slip. When there is lateral shear force such as the weight of the stone or wind load, the teeth, grooves, or corrugated sides of the interlocking surfaces will generate direct mechanical interference, providing resistance far exceeding that of planar friction, fundamentally eliminating the risk of slippage between the hanging components.

[0035] Preferably, regarding the anti-slip structure 600 mentioned above, several structural designs are provided, as follows: Firstly, the anti-slip structure includes a series of parallel anti-slip ripples with a continuous sinusoidal wave pattern on the top surface of the vertical bearing base 100, the top and bottom surfaces of the horizontal overlapping portion 210, and the bottom surface of the locking cover 400. The sinusoidal wave pattern has the advantages of uniform stress distribution and no stress concentration, ensuring smooth contact during clamping and can accommodate minor installation non-parallelism.

[0036] Preferably, the continuous sinusoidal wave pattern is designed with smooth transitions between peaks and troughs, a wave height of 1.0–3.5 mm, and a wavelength of 4–10 mm. This achieves the best balance between ensuring sufficient engagement depth and avoiding excessive local stress.

[0037] Secondly, the anti-slip structure 600 includes a series of parallel convex teeth and grooves with serrated or trapezoidal cross sections on the top surface of the vertical bearing base 100, the top and bottom surfaces of the horizontal overlapping part 210, and the bottom surface of the locking cover 400.

[0038] Preferably, in the three-layer stacked structure consisting of the vertical bearing base 100, the horizontal overlapping part 210, and the locking cover 400, there are two sets of upper and lower adjacent surfaces. The tooth grooves on these two sets of upper and lower adjacent surfaces are aligned, and the size of the protruding teeth is slightly smaller than that of the grooves, so that they can be interlocked during compression. The sawtooth or trapezoidal protruding teeth and the grooves form a mechanical keyway-type limit after compression. The protruding teeth are embedded in the grooves to create a rigid engagement, and no relative sliding will occur even under horizontal thrust or temperature difference deformation.

[0039] Thirdly, the anti-slip structure 600 includes uniformly distributed, three-dimensional diamond-shaped protrusions, wave-shaped ridges, or hemispherical protrusion arrays processed or pressed on the top surface of the vertical bearing base 100, the top and bottom surfaces of the horizontal overlapping part 210, and the bottom surface of the locking cover 400; and the protrusion array patterns on the upper and lower surfaces correspond to each other.

[0040] Preferably, in the three-layer stacked structure consisting of the vertical bearing base 100, the horizontal overlapping part 210, and the locking cover 400, there are two sets of upper and lower surfaces. The tooth grooves on these two sets of upper and lower surfaces are aligned, and the size of the protruding teeth is slightly smaller than that of the grooves, so that they can interlock during compression. The array of diamond-shaped protrusions, wavy ridges, or hemispherical protrusions forms multi-point extrusion friction after the three layers are compressed. The protrusions interlock with the corresponding concave points to create point-to-surface contact limiting, resulting in low local stress and excellent fatigue resistance, making it particularly suitable for environments with large temperature variations.

[0041] Preferably, one or two elastic rubber strips are embedded in the top and / or bottom surface of the horizontal overlapping portion 210 of the L-shaped connecting assembly 200, and the surface of the rubber strips is provided with micro-textures. When compressed, the embedded elastic rubber strips work together with the metal anti-slip structure 600 to provide additional damping and auxiliary friction, absorb vibration energy, and further improve anti-slip reliability.

[0042] Preferably, the L-shaped connecting assembly 200 is integrally formed from high-strength aluminum alloy. The integral forming of high-strength aluminum alloy ensures that the horizontal overlapping part 210 and the vertical connecting part 220 have sufficient bending stiffness, while reducing the overall weight and facilitating high-altitude transportation and installation.

[0043] Preferably, the vertical connecting part 220 may be provided with shallow indentations or scale marks for auxiliary positioning, which facilitates quick judgment and recording of the adjustment position during construction; the shallow indentations or scale marks can intuitively display the adjustment distance, which facilitates construction personnel to quickly verify the position and record data, thereby improving installation accuracy and traceability.

[0044] Preferably, the horizontal overlap 210 has a length of 80-150mm and a width of 40-60mm, and the vertical connection 220 has a height of 60-100mm and a thickness of 6-10mm.

[0045] The L-shaped connecting component 200 can be designed as a series of standard parts with different lengths, widths, or thicknesses according to different stone specifications and load levels. However, its interface dimensions with the vertical bearing base 100 and locking cap 400 remain consistent, such as the anti-slip texture tooth pitch and the hole diameter of the locking component 500, to ensure the universality and interchangeability of the components. The serialized design allows the same set of interface standards to be adapted to various types of stone, reducing the variety of items in inventory and enabling quick replacement and maintenance.

[0046] Regarding the structural design of the locking component 500, several preferred structural designs are provided, as follows: In the first structure, the locking assembly 500 includes two sets of locking units symmetrically arranged on the vertical support base 100. Each set of locking units includes two locking units respectively arranged on both sides of the horizontal overlapping part 210. The vertical support base 100 and the locking cover 400 are provided with locking screw grooves that cooperate with the locking units. The locking assembly 500 includes a locking screw 510 that passes through the locking screw groove, and one end of the locking screw 510 is provided with an adjusting handle 520 for constituting the operating part. The two sets of locking units arranged symmetrically achieve uniform clamping through synchronous manual operation, avoiding tilting or loosening caused by force on one side.

[0047] For this screw structure, several preferred structural designs are provided, as follows; Firstly, the locking assembly 500 further includes a locking seat, which is provided with a connecting screw that connects to the vertical bearing base 100 or the locking cover 400. The locking seat has a locking groove that cooperates with the locking screw 510. The adjusting handle 520 is connected to the locking seat through an eccentric wheel, and the eccentric wheel cooperates with the locking screw 510. The locking screw 510 is provided with a locking element that cooperates with the eccentric wheel.

[0048] The locking element is configured as a locking nut or a locking pin; the extension height of the locking screw 510 is controlled by the eccentric wheel. The rotation of the eccentric wheel changes the extension height of the screw, achieving rapid self-locking, preventing reverse loosening, and ensuring long-term stability.

[0049] Secondly, the adjusting handle 520 is configured as a foldable T-shaped handle hinged to the head of the locking screw 510, and the locking screw 510 is provided with fasteners.

[0050] The fastener is configured as a fastening nut or a fastening pin. The foldable T-handle can be folded and stored when not in operation, reducing the risk of collisions during high-altitude operations, and provides a larger lever arm when unfolded, making it easier to apply force by hand.

[0051] Thirdly, the threaded section of the locking screw 510 adopts a fine-pitch thread or a modified thread with self-locking characteristics. The adjusting handle 520 is set as a wing nut, and the wing nut has large, ergonomically designed wings on both sides for hand tightening. The fine-pitch self-locking thread combined with the wing nut wing design allows the operator to complete high-torque tightening with one hand. At the same time, the washer and anti-slip washer 540 enhance the friction of the contact surface and prevent the thread from loosening.

[0052] In the above-mentioned screw structure, the screw is provided with a locking washer 530 and an anti-slip washer 540 that cooperate with the locking nut or fastening nut or wing nut.

[0053] The second structure includes two sets of locking modules symmetrically arranged on both sides of the vertical support base 100. Each locking module includes a latch base fixed to the locking cover 400 and a pressing lever mounted on the side of the vertical support base 100 or the locking cover 400 via a rotating shaft. The end of the pressing lever has a hook-like part, and the latch base has a protruding locking platform. Its structure is similar to current latch structures. The pressing lever rotates via the rotating shaft to make the hook-like part engage with the locking platform, achieving instantaneous self-locking. Tightening can be completed with a single press, making the operation fast and operable with one hand.

[0054] The third structure includes two locking modules, one on each side of the vertical L-shaped connecting assembly 200. Each locking module includes a support with a wedge-shaped inclined groove integrally or fixedly connected to the vertical support base 100, and an independent wedge block. The locking cover 400 has a square hole or clearance groove at a corresponding position to allow the wedge block to pass through. When the wedge block is tapped or pushed along the inclined groove, it generates a progressive wedging force. The square hole and clearance groove ensure accurate positioning of the wedge block, achieving rapid locking without rotation.

[0055] Preferably, the vertical connecting part 220 is fixedly connected to the stone curtain wall 800 by back bolts, washers, and nuts, with the back bolts passing through the elongated adjustment holes 230. The back bolt unit 310 cooperates with the elongated adjustment holes 230 to form a slidable connection, which ensures the transfer of stone load and allows for fine-tuning of the position on site.

[0056] The adjusting screw unit 300 includes a back bolt screw 310 fixed on the stone, and the back bolt screw 310 is provided with a back bolt nut 320, a back bolt washer 330 and an anti-loosening washer 340.

[0057] Furthermore, the adjusting screw unit 300 is provided with a joint adjusting component 700 for controlling the gap between two adjacent curtain wall stones.

[0058] The joint adjustment component 700 includes a circular patch 710, which has a circular groove that mates with the back bolt 310. The circular patch 710 is provided with a first strip 720 and a second strip 730, which are perpendicularly arranged. Both the first strip 720 and the second strip 730 are provided with a joint control block 740. The circular patch 710 of the joint adjustment component 700 is in close contact with the back of the stone. The first strip 720 and the second strip 730 control the horizontal and vertical joint gaps respectively. After sliding, the joint control block 740 adheres to the sidewall of the adjacent stone, forming a rigid limiting reference.

[0059] To balance construction efficiency and adjustment flexibility, the joint adjustment component 7 preferably provides the following two structural designs: Firstly, the joint adjustment component 700 adopts a factory-prefabricated structure. The joint control block 740 and the first or second adhesive strip 720 are fixed together during the production stage through integral molding, welding, or high-strength adhesive bonding, forming a non-adjustable rigid structure. This structure allows for prefabrication in the factory for different sizes and specifications of stone, specifically adapting to the stone installation needs of particular projects. This significantly improves on-site assembly efficiency, enabling immediate positioning upon installation and avoiding time losses caused by secondary on-site adjustments. It is a core component for achieving industrialization and standardization in curtain wall construction.

[0060] Secondly, the seam adjustment component 700 is configured as an adjustable structure. The seam control block 740 has a groove that mates with the first adhesive strip 720 or the second adhesive strip 730, and a seam control screw 750 is provided on the seam control block 740. Tightening the seam control screw 750 fixes the seam control block 740 in the groove position, achieving permanent and precise control of the bidirectional seam gap.

[0061] This structure can be flexibly adjusted in size according to the actual on-site construction conditions, effectively adapting to various complex on-site construction situations, and providing post-construction compensation for deviations in stone processing or keel installation. Compared to fixed structures, it has stronger adaptability and a wider range of applications, ensuring installation accuracy when facing irregular walls or irregularly shaped stones in large-scale construction.

[0062] A method for constructing curtain wall stone, characterized by comprising the following steps: S1. Fix the vertical bearing base 100 onto the building keel 900; S2. Connect the L-shaped connecting assembly 200 to the back bolt 310 pre-installed on the back of the stone through the elongated adjustment hole 230 of its vertical connecting part 220, and adjust the position of the L-shaped connecting assembly 200 relative to the stone along the elongated adjustment hole 230; utilize the adjustment capability of the structure itself to absorb early errors, creating conditions for subsequent precise installation. S3. Place the horizontal overlap 210 of the L-shaped connecting component 200 with stone connected in step S2 on the top surface of the vertical support base 100, so that the anti-slip structure 600 provided on the top surface of the vertical support base 100 and the bottom surface of the horizontal overlap 210 initially contact each other. S4. Cover the top surface of the horizontal overlap 210 with the locking cap 400, so that the anti-slip structure 600 on the bottom surface of the locking cap 400 and the anti-slip structure 600 on the top surface of the horizontal overlap 210 are in initial contact. S5. By manually operating the operating part of the locking assembly 500, the locking assembly 500 is driven to sequentially connect and press the locking cover 400, the horizontal overlapping part 210, and the vertical bearing base 100 until the anti-slip structures 600 on each component interlock, completing the installation of a single stone piece. The manual operation in step S5 utilizes the operating part of the locking assembly 500 (rotation, pressing, or pushing) to achieve simultaneous pressing of the three components. After the anti-slip structures 600 interlock, they generate mechanical limiting and frictional force, ensuring connection rigidity and anti-slip performance.

[0063] In step S2, the operation of adjusting the position of the L-shaped connecting component 200 is used to compensate for errors in on-site layout or stone processing.

[0064] In step S5, the manual operation includes rotating the adjustment handle 520, turning the pressing lever, or hammering in the wedge block, and no external special tools such as wrenches or screwdrivers are used during the operation.

[0065] Furthermore, after step S2 and before step S3, step S2a is also included: installing the joint adjustment component 700 on the back bolt 310 on the back of the stone. The joint adjustment component 700 includes a strip with a joint control block 740; after the installation of a single stone is completed, the component further includes step S5a: fitting the joint control block 740 against the side wall of the adjacent installed stone to control the width of the gap between the stones.

[0066] Preferably, when the joint control block 740 of the joint adjustment component 700 has a groove, in step S5a, the joint control block 740 is slid to fit against the side wall of the stone, and then the joint control screw 750 is tightened to fix it.

[0067] Furthermore, after step S5, step S6 is also included: checking whether the anti-slip structure 600 between the vertical bearing base 100, the horizontal overlapping part 210 and the locking cover 400 is tightly engaged, and the locking status of the locking assembly 500.

[0068] Repeat steps S2 to S5 to install adjacent stones. When installing adjacent stones, control the flatness between adjacent stones by observing or ensuring that the joint adjustment component 700 strip is fully in contact with the back of the stone. During repeated installation, the joint adjustment component 700 strip serves as a common reference surface, achieving interlocking control of the flatness and verticality of multiple stones, thus ensuring the overall surface finish quality.

[0069] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
