Description

Technical Field

[0001] This invention relates to the field of glass curtain wall technology, and more specifically, to a concealed aluminum alloy glass base for curtain wall renovation. Background Technology

[0002] Reference Figure 5 The traditional construction method for a conventional frameless glass skylight with a circular tube frame involves welding a U-shaped steel base onto the circular steel tube frame, and then assembling aluminum alloy profiles onto the U-shaped steel base. Before glass installation, the glass sub-frame must be pre-assembled onto the inner edge of the skylight glass, and then the framed glass is installed onto the zinc alloy profiles. After this traditional method, the aluminum alloy profiles are clearly exposed, affecting the overall aesthetics of the skylight, and the construction process is cumbersome. Furthermore, it requires a large amount of aluminum and significant labor costs, ultimately resulting in low construction efficiency and poor project economics. In addition, the U-shaped steel base is welded to the circular tube frame on-site, which can easily cause frame deformation. Summary of the Invention

[0003] In view of this, the present invention proposes a concealed aluminum alloy glass base for curtain wall renovation to solve the problems existing in the prior art.

[0004] To achieve the above objectives, the present invention proposes a concealed aluminum alloy glass base for curtain wall renovation, comprising a circular tube, a circular tube connector, a first fastener, a buffer support, and a pressure plate; The circular tube is disposed on the indoor side of the first double-glazed glass and the second double-glazed glass. The circular tube connector is fixedly mounted on the arc-shaped surface of the circular tube by the first fastener; The two sides of the circular tube connector opposite to the circular tube are respectively in contact with the first double-layer glass and the second double-layer glass through the buffer support; The middle part of the circular tube connector is located in the gap between the first double-layer glass and the second double-layer glass; The middle part of the pressure plate is fixedly connected to the middle part of the round tube connector, and the two sides of the pressure plate are respectively embedded in the interlayer of the first double-layer glass and the second double-layer glass to press the first double-layer glass and the second double-layer glass tightly.

[0005] In some embodiments of the present invention, the circular tube connector includes an arc-shaped plate and a connecting protrusion disposed on the top of the arc-shaped plate; The arc-shaped plate fits against the outer wall of the circular tube, and the top of the connecting protrusion is fixedly connected to the pressure plate.

[0006] In some embodiments of the present invention, the round tube connector has first mounting portions on both sides, and the bottom of the buffer support has a buckle for being embedded into the first mounting portions.

[0007] In some embodiments of the present invention, the top of the buffer support has a buffer portion, which is a linearly arranged sawtooth structure for supporting the first double-layer glass and the second double-layer glass, and at least the buffer portion is made of an elastic material.

[0008] In some embodiments of the present invention, the middle portion of the pressure plate has two first limiting protrusions on the side facing the circular tube connector, and the width of the two first limiting protrusions is adapted to the width of the connecting protrusion.

[0009] In some embodiments of the present invention, the base further includes two bushings, which are installed in the interlayer between the first double-glazed glass and the second double-glazed glass. The bushings have a U-shaped cross-section, and the ends of the bushings that are far apart from each other have snap-fit ​​protrusions for embedding into the interlayer between the first double-glazed glass and the second double-glazed glass.

[0010] In some embodiments of the present invention, the pressure plate has bearing protrusions at both ends facing the circular tube connector, and the bearing protrusions are in contact with the inner bottom surface of the bushing; The end of the inner bottom surface of the bushing has a second limiting protrusion, and the bearing protrusion is arranged facing the second limiting protrusion.

[0011] In some embodiments of the present invention, gaskets are provided between the upper and lower outer walls of the bushing and the interlayer of the first double-glazed glass and the second double-glazed glass.

[0012] In some embodiments of the present invention, the pressure plate and the round tube connector are fixedly connected by a second fastener, and a sealing strip is provided on the top of the pressure plate.

[0013] In some embodiments of the present invention, both the first double-layer glass and the second double-layer glass include a first glass and a second glass arranged in parallel, with a filler provided between the first glass and the second glass, and an installation position reserved between the filler and the outer edges of the first glass and the second glass for installing the bushing.

[0014] Compared with existing technologies, the advantages of this invention lie in its optimization of the shortcomings of conventional round tube frame concealed glass skylights. The specific structure and advantages are as follows: A round steel tube serves as the skylight's steel frame, with pre-drilled holes on the tube. A custom-molded, compact aluminum alloy base is securely fixed using stainless steel screws. A bushing is pre-assembled within the hollow layer of the skylight glass, and then a pressure plate is used to install and lock the entire glass onto the aluminum alloy base. In this solution, the aluminum alloy base, due to its customized compact design, is essentially not exposed after installation, ensuring the overall aesthetics of the skylight. Simultaneously, it simplifies traditional multi-step assembly processes, reduces aluminum consumption, and lowers labor costs, combining aesthetics and economy. Attached Figure Description

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Reference Figure 1 and Figure 2 This embodiment proposes a concealed aluminum alloy glass base for curtain wall renovation, including a circular tube 1, a circular tube connector 2, a first fastener 3, a buffer support 4, and a pressure plate 5.

[0019] The circular tube 1 is disposed on the indoor side of the first and second double-glazed windows; the circular tube connector 2 is fixedly disposed on the arc-shaped surface of the circular tube 1 by the first fastener 3; the two sides of the circular tube connector 2 away from the circular tube 1 are respectively in contact with the first and second double-glazed windows by the buffer support 4; the middle part of the circular tube connector 2 is located in the gap between the first and second double-glazed windows; the middle part of the pressure plate 5 is fixedly connected to the middle part of the circular tube connector 2, and the two sides of the pressure plate 5 are respectively embedded in the interlayer of the first and second double-glazed windows to press the first and second double-glazed windows together.

[0020] In the above embodiments, the circular tube connector 2 is directly fixed to the arc-shaped surface of the circular tube 1 using the first fastener 3, completely avoiding the frame deformation problem caused by on-site welding of the U-shaped steel base. Simultaneously, the central part of the circular tube connector 2 is located within the gap between the first and second double-layered glass, and with the glass interlayer embedded on both sides of the pressure plate 5 and pressed against the glass, all aluminum alloy components are hidden inside the glass or in the gap, significantly improving the overall aesthetics of the skylight and achieving a truly concealed design. Furthermore, the buffer support 4 supports the circular tube connector 2 and the glass on both sides, simplifying the installation process, eliminating the need for pre-assembly of the glass subframe, greatly reducing aluminum consumption and labor costs, thereby effectively improving construction efficiency and project economy.

[0021] In some embodiments, refer to Figure 3 The circular tube connector 2 includes an arc-shaped plate 21 and a connecting protrusion 23 on the top of the arc-shaped plate 21. The arc-shaped plate 21 can achieve a large-area tight fit with the outer wall of the circular tube 1, and a stable and reliable connection can be obtained through the first fastener 3, eliminating the welding process and the deformation risk it brings from the root. The connecting protrusion 23 at the top, as a load-bearing and force-transmitting component directly fixed to the pressure plate 5, guides the support point to the center line of the gap between the two glass panes.

[0022] The curved plate 21 fits against the outer wall of the circular tube 1, and the top of the connecting protrusion 23 is fixedly connected to the pressure plate 5. The clamping force from the pressure plate 5 is transmitted vertically downward through the connecting protrusion 23, and then evenly distributed to the circular tube 1 via the integral circular tube connector 2. This not only ensures that the clamping force of the pressure plate 5 on the glass is balanced and stable, but also makes the entire connection and support system extremely simple and efficient, greatly reducing the number of components and assembly steps.

[0023] In some embodiments, the round tube connector 2 has a first mounting portion 22 on both sides, and the bottom of the buffer support 4 has a buckle 41. The buckle 41 is used to be embedded into the first mounting portion 22, which realizes the quick and accurate installation of the buffer support 4 and the round tube connector 2. During installation, the buckle 41 only needs to be aligned and embedded into the first mounting portion 22 to complete the mechanical locking.

[0024] This design allows the buffer support 4, even when fixed, to absorb the minute displacements and stresses of the glass pane caused by temperature changes or external forces through its own slight deformation. The load is then smoothly transferred to the circular tube connector 2 and the main structure via the first mounting part 22. This effectively protects the glass edges and avoids the risk of stress concentration or glass breakage caused by hard contact.

[0025] In some embodiments, refer to Figure 4 The top of the buffer support 4 has a buffer part 42, which is a linearly arranged sawtooth structure used to support the first double-layer glass and the second double-layer glass. At least the buffer part 42 is made of elastic material.

[0026] In the above embodiments, the serrated structure significantly increases the coefficient of friction with the first and second double-glazed windows, providing excellent anti-slip stability and enhancing the overall structure's resistance to wind pressure and vibration. The combination of elastic material and serrated shape allows each serrated unit to undergo independent micro-elastic deformation, thereby efficiently discretizing the surface load transmitted by the glass into multiple point loads for absorption and redistribution. This design can adapt to the minute deformations and displacements of the glass panel under temperature changes or loads, avoiding stress concentration at the glass edges caused by localized hard contact or deformation inconsistencies in traditional flat gaskets, fundamentally reducing the risk of spontaneous glass breakage.

[0027] In some embodiments, the middle portion of the pressure plate 5 facing the circular pipe connector 2 has two first limiting protrusions 51, the width of which is adapted to the width of the connecting protrusion 23. During the assembly of the pressure plate 5, the first limiting protrusions 51 automatically engage with both sides of the connecting protrusion 23, achieving rapid and precise alignment. This completely prevents the pressure plate 5 from shifting laterally or rotating during installation, greatly improving construction efficiency and accuracy.

[0028] In some embodiments, the base further includes two bushings 7, which are installed in the interlayer between the first double-glazed glass and the second double-glazed glass. The bushings 7 have a U-shaped cross-section and the ends of the bushings 7 that are far apart from each other have snap-fit ​​protrusions 71 for embedding into the interlayer between the first double-glazed glass and the second double-glazed glass.

[0029] In the above embodiments, the bushing 7 efficiently and evenly transmits and distributes the concentrated clamping force applied by the pressure plate 5 across the entire interlayer width of the double-glazed glass through its U-shaped sidewall structure, avoiding excessive concentration of local stress in the glass and improving the compressive and bending resistance of the glass edges. The design of the snap-fit ​​protrusion 71 ensures the pre-positioning and anti-detachment of the bushing 7 in the glass interlayer, allowing the bushing 7, glass, and pressure plate 5 to be modularly pre-assembled before on-site installation, requiring only overall snap-fit ​​on-site, simplifying the final installation steps. In addition, the presence of the bushing 7 provides the pressure plate 5 with a flat, sturdy, and concealed interlocking base inside the glass, eliminating the exposure of fasteners and achieving a visually concealed effect.

[0030] In some embodiments, the pressure plate 5 has bearing protrusions 52 at both ends facing the circular tube connector 2, and the bearing protrusions 52 are in contact with the inner bottom surface of the bushing 7. The bearing protrusions 52 serve as rigid contact points between the pressure plate 5 and the bushing 7, accurately and centrally transmitting the clamping force from the fastening system to a specific position on the bushing 7, and then dispersing it to the glass interlayer via the U-shaped structure of the bushing 7. This point-to-point force transmission path is clear and efficient, avoiding pressure plate deformation or stress ambiguity caused by excessively large or uneven contact surfaces.

[0031] The inner bottom surface of the bushing 7 has a second limiting protrusion 72 at its end, and the bearing protrusion 52 is arranged facing the second limiting protrusion 72. When the pressure plate 5 is installed in place, a limiting range is naturally formed in the length direction of the glass, which effectively prevents the pressure plate 5 from sliding longitudinally due to vibration or temperature changes during use.

[0032] In some embodiments, gaskets 9 are provided between the upper and lower outer walls of the bushing 7 and the interlayer of the first and second double-glazed glass. The gaskets 9 can not only effectively buffer the hard contact between the bushing 7 and the glass and absorb the small displacements caused by installation tolerances and thermal expansion and contraction, but also fill the gaps and prevent rainwater or condensate from seeping into the glass interlayer through capillary action, thereby structurally improving the sealing performance of the joint.

[0033] In some embodiments, the pressure plate 5 and the round tube connector 2 are fixedly connected by a second fastener 6, and the top of the pressure plate 5 is provided with sealing foam 8 and sealing strip 10. The combination of the second fastener 6 and the sealing strip 10 ensures both internal connection strength and external environmental sealing, so that the entire concealed base achieves a high level of structural safety and waterproof durability while maintaining a simple and beautiful appearance.

[0034] In some embodiments, both the first double-glazed glass and the second double-glazed glass include a first glass 11 and a second glass 12 arranged in parallel. A filler 13 is provided between the first glass 11 and the second glass 12. An installation position is reserved between the filler 13 and the outer edges of the first glass 11 and the second glass 12 for installing the bushing 7.

[0035] In the above embodiments, the bushing 7 can be pre-precisely embedded into the rigid cavity enclosed by the first glass 11, the second glass 12, and the filler 13, so that the glass panels are integrated with the key load-bearing frame at the factory. During on-site installation, it is only necessary to connect with external components such as the pressure plate 5, which greatly simplifies the on-site process and improves installation efficiency and accuracy. The reserved installation position ensures that the bushing 7, as a rigid core, is uniformly wrapped by the filler 13. The clamping force from the pressure plate 5 is directly and uniformly transmitted to the inner surface of the two glass panels through the bushing 7, effectively avoiding stress concentration at the glass edge or creep damage to the filler 13 caused by local point loads or improper compression.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
