Technical Field
[0001] This utility model relates to a top and bottom connection system for a screen-type glass curtain wall. Background Technology
[0002] Screen-style glass curtain walls are favored by various architectural stakeholders for their light visual appeal and versatile decorative effects, especially suitable for projects with high requirements for facade diversity, aesthetics, and practicality, such as commercial buildings, hotels, and office buildings. However, traditional screen-style glass curtain walls often use a U-shaped groove connection method at the top and bottom. This type of connection is time-consuming and labor-intensive to install, and if the glass breaks after installation, there is a risk of overall collapse or detachment, posing significant hidden dangers to construction, installation, subsequent use, and maintenance. At the same time, the traditional U-shaped groove connection can also damage the waterproof layer of the main structure at the top and bottom, which is detrimental to later use and maintenance. The curtain wall industry has made various attempts to improve this, but problems such as inconvenient installation, potential dangers, and low waterproof reliability have not been effectively solved. The industry's demand for safe and reliable screen-style glass curtain walls is becoming increasingly urgent.
[0003] For example, utility model CN202120941190.2 discloses an angle-adjustable curtain wall panel, including a surrounding panel. A U-shaped frame is hinged to the top of the surrounding panel, and a glass panel is slidably installed inside the U-shaped frame. A sealing plate is detachably installed on one side wall of the U-shaped frame via screws. T-shaped limiting grooves are provided at both ends of the bottom of the U-shaped frame, and T-shaped limiting blocks are slidably connected inside each T-shaped limiting groove. A U-shaped connector is fixed to the bottom of each T-shaped limiting block, and a vertical rod is rotatably connected to each U-shaped connector via a pin. This utility model, by setting up U-shaped connectors, vertical rods, and a lifting mechanism, allows for convenient and quick adjustment of the angle of the U-shaped frame, thus exhibiting strong adaptability. Furthermore, since the sealing plate and U-shaped frame are detachably installed via screws, the sealing plate can be easily removed and the glass panel replaced if the glass panel is damaged.
[0004] The aforementioned utility model can only accommodate rotation in one direction. How to solve the problem of adapting to deformation in all directions (front, back, left, right, up, and down) of large-size screen-type curtain walls, while ensuring their safety and reliability, remains a challenge in the industry. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide a top and bottom connection system for screen-type glass curtain walls, which addresses the installation and deformation adaptation of large-sized glass decorative panels.
[0006] This utility model provides a top and bottom connection system for a screen-type glass curtain wall. The screen-type glass curtain wall includes glass panels connected as one piece, a base U-shaped steel channel for fixing and clamping the glass, and a top U-shaped steel channel. The screen-type glass curtain wall is suspended from the main structure at the top and bottom via the top and bottom connection systems.
[0007] The top connection system connects the telescopic steel plate and the top U-shaped steel channel with stainless steel bolts. Sufficient gaps are left between the telescopic steel plate and the top U-shaped steel channel to facilitate the release of rotation under horizontal loads. The telescopic steel plate has elongated holes in the vertical direction to absorb expansion and contraction deformation under vertical loads. At the same time, the connecting part of the top U-shaped steel channel has elongated holes in the horizontal direction to absorb in-plane deformation. The steel pressure plate and the steel connecting plate are connected by stainless steel machine screws, and a high-strength ball joint pad is set between the steel pressure plate and the top U-shaped steel channel.
[0008] The bottom connection system is connected to the bottom main structure, including a bottom supporting steel frame. The bottom supporting steel frame is supported on the bottom of the U-shaped steel channel of the base. The steel pressure plate is connected to the bottom supporting steel frame by stainless steel machine screws. A high-strength ball joint pad is set between the steel pressure plate and the bottom U-shaped steel channel.
[0009] The U-shaped steel channel at the base and the top U-shaped steel channel are filled with epoxy resin structural adhesive between themselves and the glass. This ensures that the glass is evenly stressed at the top and bottom. In the event of glass breakage, this structure ensures that the glass remains suspended on the main structure and does not collapse as a whole.
[0010] The top connection system is connected to the main steel structure at the top via square steel tubes and U-shaped connectors.
[0011] The high-strength ball joint pad is composed of a rigid PTFE spherical pad and a steel plate. The steel plate is fitted to the inner side of the steel pressure plate, and the rigid PTFE spherical pad abuts against the side walls of the top U-shaped steel channel and the base U-shaped steel channel. It can absorb rotational deviations of about 10° and reduce noise on the contact surface under various loads.
[0012] Sufficient gaps are left between the telescopic steel plate and the top U-shaped steel channel to facilitate the release of rotation under horizontal loads; the telescopic steel plate is provided with elongated holes in the vertical direction to absorb expansion and contraction deformation under vertical loads.
[0013] The bottom connection system is fixed to the bottom main structure using stainless steel bolts and steel adapters.
[0014] The bottom connection system is fixed to the bottom main structure in sequence from top to bottom through steel adapters, U-shaped connectors, and pre-embedded steel parts in the main structure.
[0015] The steel adapter, U-shaped connector, and pre-embedded steel components of the main structure are installed below the ground decoration layer.
[0016] The beneficial effects of this utility model are: it enables rapid installation and deformation adaptability of large-sized glass decorative panels at the top and bottom, significantly improving the safety and reliability of the system. The provided screen-type glass curtain wall top and bottom connection system not only achieves rapid installation, but also features a high-precision, safe, and reliable installation structure.

[0034] The top connection system 200, such as Figure 2 and Figure 4 As shown, the structure is suspended from the main steel structure 12 at the top via a square steel tube 10 and a U-shaped connector 11. A telescopic steel plate 09 and a top U-shaped steel channel 15 are connected by stainless steel bolts 07. Sufficient gaps are left between the telescopic steel plate 09 and the top U-shaped steel channel 15 to facilitate the release of rotation under horizontal loads. The telescopic steel plate 09 has elongated holes in the vertical direction to absorb expansion and contraction deformation under vertical loads. Simultaneously, the connecting part of the top U-shaped steel channel 15 has elongated holes in the horizontal direction to absorb in-plane deformation. A steel pressure plate 04 is connected to a steel connecting plate 08 via stainless steel machine screws 06. A high-strength ball joint pad 03 is placed between the steel pressure plate 04 and the top U-shaped steel channel 15.
[0035] The bottom connection system 300, such as Figure 1 and 3 As shown, the bottom main structure is connected by a steel adapter 17, a U-shaped connector 11 and a main structure embedded steel part 18 from top to bottom, and the steel adapter 17, the U-shaped connector 11 and the main structure embedded steel part 18 are set below the ground decoration layer 14.
