Description

Technical Field

[0001] This utility model relates to the field of curtain wall decoration technology, and in particular to a screwless hanging system for sunshade profiles of large cantilever curtain walls. Background Technology

[0002] With the continuous development of modern architectural design concepts, curtain walls, as an important component of building envelopes, are receiving increasing attention for their functionality and aesthetic appeal. In the pursuit of energy conservation and the creation of unique facade designs, the application of curtain wall sun-shading decorative lines is becoming increasingly widespread. These sun-shading lines not only effectively block solar radiation and reduce indoor energy consumption, but also enrich the layers of the building facade and enhance the overall artistic effect.

[0003] However, traditional installation methods for curtain wall sunshade decorative lines generally use direct screw connections, a fixing method that has revealed numerous problems in practical applications. First, screw connections have limited load-bearing capacity. Especially when the sunshade lines need to achieve a large overhang, the increased lever arm causes the front end of the line to sag and deform, severely affecting the flatness and aesthetics of the building's appearance, which is inconsistent with the refined and high-quality requirements of modern architecture. Second, fixing screws through curtain wall beams or columns often damages the integrity of the profiles, creating potential leakage hazards. Over time, the sealant at the screw holes may age and fail, allowing rainwater to seep into the curtain wall, affecting the building's waterproofing performance and internal environment. Furthermore, the installation process with screw connections is usually cumbersome, requiring precise hole alignment and tightening, increasing construction difficulty and labor costs. Disassembly is also relatively inconvenient if repairs or replacements are needed.

[0004] While some experimental improvement solutions exist in existing technologies, most fail to fundamentally resolve the contradiction between structural stability, waterproofing, and installation efficiency of overhanging sunshade lines. For example, increasing the number or diameter of screws to improve load-bearing capacity still carries the risk of leakage due to screw penetration and causes greater damage to the profile; alternatively, welding can be used, but on-site welding is not only limited by the environment but may also affect the surface treatment and material properties of the profile.

[0005] Solving the aforementioned technical problems is the challenge facing this utility model. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a reasonably designed, safe, and reliable heavy-duty door floor spring anti-sway reinforcement support device.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a screwless hanging system for sunshade profiles of large cantilevered curtain walls.

[0008] It includes several cantilever arms horizontally set on the curtain wall beam, the curtain wall beam is provided with a connecting groove that cooperates with the cantilever arms, and one end of the cantilever arm is provided with a connecting point that slides with the connecting groove.

[0009] A sunshade decorative strip is provided between two adjacent cantilever arms, and a connection slot that mates with the cantilever arm is provided on both sides of the sunshade decorative strip; in use, the sunshade decorative strip is located between the upper and lower curtain walls, and curtain wall columns that are fixedly connected to the wall surface are provided at both ends of the curtain wall beam.

[0010] The preferred design provides two types of connection points and corresponding connection slots, as detailed below:

[0011] Firstly, the connecting hook is a hook-shaped structure that can be inserted into the connecting slot and locked in the vertical direction. The connecting hook and the cantilever arm are fixedly connected by riveting, casting or integral molding to achieve rapid assembly and firm positioning of the cantilever arm.

[0012] Secondly, the connecting groove has a dovetail structure, and the connecting point is a T-shaped or L-shaped point that matches the dovetail structure. The cantilever arm is slidably connected to the dovetail connecting groove on the curtain wall beam through the T-shaped or L-shaped point.

[0013] The cross-section of the cantilever arm is rectangular or I-shaped to enhance its structural strength and load-bearing capacity.

[0014] Furthermore, the curtain wall beam is horizontally provided with an upper connecting groove and a lower connecting groove, and a connecting slide plate is provided at one end of the cantilever arm. The connecting slide plate is provided with an upper connecting point that cooperates with the upper connecting groove, and a lower connecting point that cooperates with the lower connecting groove. In use, the cantilever arm slides into the curtain wall beam from the side end, so that the cantilever arm and the curtain wall beam are connected as one unit.

[0015] Preferably, an elastic buffer pad is provided between the connecting slide plate of the cantilever arm and the curtain wall beam, and an elastic buffer pad or sealing strip is provided inside the connecting groove to enhance the connection stability between the sunshade decorative strip and the cantilever arm and the overall sealing performance of the system, prevent water leakage and improve durability.

[0016] Preferably, the distance between the upper connecting hanging point and the lower connecting hanging groove is 80-150mm, and the cross-sectional width of the cantilever arm is 200-250mm and the thickness is 20-30mm. The distance and cross-sectional dimensions are optimized through mechanical calculations to ensure the structural stability and load transfer reliability of the cantilever arm when the cantilever distance is greater than 300mm.

[0017] Preferably, the distance between the upper connecting hanging point and the lower connecting hanging groove is 120mm, and the cross-sectional width of the cantilever arm is 220mm and the thickness is 25mm.

[0018] Furthermore, the cantilever arm, the curtain wall beam, the sunshade decorative strip, and the curtain wall column are all made of aluminum alloy profiles.

[0019] Furthermore, one end of the sunshade decorative strip is provided with a lamp decorative strip, the bottom end of the sunshade decorative strip is provided with a connecting groove that mates with the lamp decorative strip, and the lamp decorative strip is provided with a connecting block that mates with the connecting groove;

[0020] The decorative strip of the lamp has a lamp mounting groove, and the decorative lamp is installed in the lamp mounting groove.

[0021] Furthermore, the cross-section of the lamp decorative strip is L-shaped, and the sunshade decorative strip and the lamp decorative strip together form a lamp mounting groove. A support plate that cooperates with the cantilever arm is provided at one end of the sunshade decorative strip near the lamp decorative strip, and a connecting screw is provided on the support plate; and the connecting screw is located in the lamp mounting groove.

[0022] This invention employs a screwless sliding connection between the cantilever arm and the curtain wall beam. In particular, the combination of hook-shaped or dovetail-type hanging points and connecting grooves, along with the dual limiting design of the upper and lower connecting grooves and the connecting sliding plate, integrates the cantilever arm and the curtain wall beam into a single unit, forming an efficient and stable mechanical transmission path. This fundamentally solves the problem of sagging and deformation at the front end of the sunshade line under large cantilever distances with traditional screw connections, ensuring the structural strength and load transfer reliability of the sunshade line.

[0023] This invention eliminates the need for holes in the curtain wall profiles by abandoning traditional screw-through connections, thus eliminating the risk of leakage that may be caused by screw holes. Combined with optimally designed elastic buffer gaskets and sealing strips, the sealing performance at the joints is further enhanced, ensuring the overall waterproofing effect of the curtain wall system and improving the building's waterproofing rating and service life.

[0024] This invention employs a hook-and-loop connection method, enabling rapid assembly and secure positioning of the cantilever arm. Installation is completed simply by sliding the cantilever arm into the side of the curtain wall beam. Compared to the cumbersome process of traditional screw connections, which require drilling, alignment, and tightening each screw individually, this system significantly simplifies the installation process, greatly shortens the construction cycle, and reduces labor costs and construction difficulty.

[0025] This invention achieves a screwless, exposed design, resulting in a cleaner and more streamlined appearance for the curtain wall sunshade profile. Furthermore, by integrating lighting trim and concealed lighting mounting slots into the sunshade trim, and cleverly hiding the connecting screws within the mounting slots, it not only provides additional lighting functionality but also avoids the aesthetic impact of traditional exposed screws, enhancing the overall artistry and sophistication of the curtain wall facade.

[0026] The sliding fit between the connecting hanger and the connecting groove in this invention, as well as the application of elastic buffer pads and sealing strips, enable the cantilever arm and the curtain wall beam to adapt to thermal expansion and contraction or free relative movement caused by temperature changes, effectively avoiding stress concentration and material fatigue, thereby extending the service life of the entire system and improving its reliability under different climatic conditions.

Detailed Implementation

[0031] See Figures 1 to 3 As shown, a screwless mounting system for sunshade profiles of large cantilevered curtain walls includes several cantilevered arms 100 horizontally arranged on a curtain wall beam 200. The curtain wall beam 200 has a connecting groove 210 that mates with the cantilevered arms 100. One end of each cantilevered arm 100 has a connecting point 500 that slides into the connecting groove 210. This design allows the cantilevered arms 100 to be easily connected to the curtain wall beam 200 without the need for additional screws, greatly improving installation efficiency.

[0032] A sunshade decorative strip 300 is provided between two adjacent cantilever arms 100. Each side of the sunshade decorative strip 300 has a connecting groove that mates with the cantilever arm 100. In use, the sunshade decorative strip 300 is positioned between the upper and lower curtain walls 800, and curtain wall columns 600, which are fixedly connected to the wall surface, are provided at both ends of the curtain wall beams 200. This layout not only achieves the sunshade function but also makes the overall structure of the curtain wall 800 more compact and aesthetically pleasing.

[0033] The preferred design provides two types of connection points 500 and corresponding connection slots 210, as detailed below:

[0034] Firstly, the connecting hook 500 has a hook-shaped structure, which can be inserted into the connecting slot 210 and locked in the vertical direction. The connecting hook 500 is fixedly connected to the cantilever arm 100 by riveting, casting, or integral molding to achieve rapid assembly and secure positioning of the cantilever arm 100. The hook-shaped structure is simple and practical, enabling quick connection between the cantilever arm 100 and the curtain wall beam 200, and has a good limiting effect in the vertical direction, ensuring the stability of the connection.

[0035] Secondly, the connecting groove 210 has a dovetail structure, and the connecting point 500 is a T-shaped or L-shaped point that matches the dovetail structure. The cantilever arm 100 is slidably connected to the dovetail connecting groove 210 on the curtain wall beam 200 through the T-shaped or L-shaped point. The combination of the dovetail structure and the T-shaped or L-shaped point further enhances the firmness and stability of the connection, while the sliding fit design also facilitates installation and disassembly.

[0036] The cantilever arm 100 has a rectangular or I-shaped cross-section to enhance its structural strength and load-bearing capacity. The rectangular or I-shaped cross-section design can effectively improve the bending and compressive strength of the cantilever arm 100, ensuring that it can maintain structural stability when subjected to large loads.

[0037] Furthermore, the curtain wall beam 200 is horizontally provided with an upper connecting groove 211 and a lower connecting groove 212. A connecting slide plate 400 is provided at one end of the cantilever arm 100. The connecting slide plate 400 has an upper connecting point 510 that mates with the upper connecting groove 211, and a lower connecting point 520 that mates with the lower connecting groove 212. In use, the cantilever arm 100 slides into the curtain wall beam 200 from its side, connecting the cantilever arm 100 and the curtain wall beam 200 as a single unit. This double-groove design makes the connection between the cantilever arm 100 and the curtain wall beam 200 more stable, while the sliding installation method greatly improves the ease of installation.

[0038] Preferably, an elastic buffer pad is also provided between the connecting slide plate 400 of the cantilever arm 100 and the curtain wall beam 200, and an elastic buffer pad or sealing strip is provided inside the connecting groove to enhance the connection stability between the sunshade decorative strip 300 and the cantilever arm 100 and the overall sealing performance of the system, prevent water leakage, and improve durability. The setting of the elastic buffer pad and sealing strip can effectively reduce wear and loosening of the connection parts, while preventing rainwater and other substances from entering the system, thereby improving the service life and reliability of the system.

[0039] Preferably, the sealing strip is made of weather-resistant silicone, which can withstand temperature changes and long-term ultraviolet radiation, ensuring the durability of the sealing performance; the elastic buffer pad is made of EPDM rubber to reduce rigid collisions and noise between the sunshade decorative strip 300 and the cantilever arm 100. The selection of weather-resistant silicone and EPDM rubber enables the sealing strip and elastic buffer pad to maintain good performance under harsh environmental conditions, ensuring the long-term stable operation of the system.

[0040] Specifically, the sunshade decorative strip 300 can be customized according to architectural design requirements, including but not limited to adjustments in length, width, and thickness, as well as the selection of surface treatment processes such as anodizing and powder coating, to meet different sunshade effects and appearance requirements. This customized production approach can meet the individual needs of different building projects, enabling the sunshade decorative strip 300 to achieve its sunshade function while also coordinating with the overall architectural style.

[0041] Preferably, the distance between the upper connecting hanging point 510 and the lower connecting hanging groove 212 is 80-150mm, and the cross-sectional width of the cantilever arm 100 is 200-250mm and the thickness is 20-30mm. The distance and cross-sectional dimensions are optimized through mechanical calculations to ensure the structural stability and load transfer reliability of the cantilever arm 100 when the cantilever distance is greater than 300mm.

[0042] Preferably, the distance between the upper connecting hanging point 510 and the lower connecting hanging groove 212 is 120mm, and the cross-sectional width of the cantilever arm 100 is 220mm and the thickness is 25mm. These are preferred size parameters that have been verified by a large number of experiments and practical applications, and can achieve good results in actual engineering.

[0043] Furthermore, the cantilever arm 100, the curtain wall beam 200, the sunshade decorative strip 300, and the curtain wall column 600 are all made of aluminum alloy profiles. Aluminum alloy profiles have advantages such as light weight, high strength, and corrosion resistance, which can effectively reduce the weight of the curtain wall 800 system and improve the system's durability and reliability.

[0044] Furthermore, a lamp decoration strip 700 is provided at one end of the sunshade decorative strip 300, and a connecting groove 710 that mates with the lamp decoration strip 700 is provided at the bottom end of the sunshade decorative strip 300. A connecting block 720 that mates with the connecting groove 710 is provided on the lamp decoration strip 700.

[0045] The decorative lighting strip 700 has a lighting mounting groove 730, in which the decorative light is installed. The decorative lighting strip 700 not only increases the lighting function of the curtain wall 800 system, but also enhances the overall aesthetics of the building's appearance.

[0046] Preferably, the structure of the plug-in connecting groove 710 is consistent with the structure of the connecting hanging groove 210; the structure of the plug-in connecting block 720 is consistent with the structure of the connecting hanging point 500. This consistent design makes the connection method between the lamp decorative strip 700 and the sunshade decorative strip 300 similar to the connection method between the cantilever arm 100 and the curtain wall beam 200, which facilitates production and installation.

[0047] The decorative lighting strip 700 has a lighting mounting groove 730 for installing decorative lights, allowing the lights to be integrated into the sunshade strip 300. This not only provides lighting functionality but also enhances the overall aesthetics of the building's exterior. The position and size of the lighting mounting groove 730 can be adjusted according to actual needs to accommodate different lighting requirements and aesthetic demands.

[0048] Furthermore, the decorative strip 700 has an L-shaped cross-section, and the sunshade strip 300 and the decorative strip 700 together form a lighting fixture mounting groove 730. A support plate that mates with the cantilever arm 100 is provided at one end of the sunshade strip 300 near the decorative strip 700, and a connecting screw is provided on the support plate; the connecting screw is located in the lighting fixture mounting groove 730. This flexible design can meet the lighting and aesthetic needs of different building projects. The L-shaped cross-section of the decorative strip 700 and the sunshade strip 300 together form the lighting fixture mounting groove 730, making the lighting fixture installation more stable. At the same time, the support plate and connecting screw further enhance the overall stability of the sunshade strip 300.

[0049] Preferably, the support plate and the cantilever arm 100 are fixedly connected by the connecting screw. The connecting screw passes through the support plate and is fixedly connected to the cantilever arm 100, thereby enhancing the overall stability and wind pressure resistance of the sunshade decorative strip 300. The connecting screw is hidden in the lamp mounting groove 730 to avoid affecting the aesthetics and waterproof performance of the curtain wall 800 facade.

[0050] Preferably, the decorative light is embedded in the light fixture mounting groove 730 and sealed with a sealing cover, which ensures the safety of the light fixture and enhances the overall aesthetics of the building facade. The sealing cover prevents rainwater, dust, etc. from entering the light fixture mounting groove 730, protecting the decorative light and improving the aesthetics of the building facade.

[0051] Preferably, the connecting screw is a countersunk screw, the head of which is fully embedded in the support plate, with an embedding depth of 2-5mm and a diameter of 4-8mm. The support plate and the cantilever arm 100 are securely connected by the countersunk screw, while ensuring that the countersunk screw does not protrude from the surface of the lamp mounting groove 730, thus avoiding interference or scratching of the decorative lamp installed in the lamp mounting groove 730 and ensuring the flatness and safety of the decorative lamp installation.
