Description

Technical Field

[0001] This utility model relates to the field of glass, and in particular to a triple-glazed, double-cavity tempered glass. Background Technology

[0002] With the continuous improvement of building energy efficiency standards, traditional single-pane or double-pane glass can no longer meet the needs of modern buildings for thermal insulation, sound insulation, and noise reduction. Triple-pane glass, with its double-cavity structure, offers significantly improved thermal and sound insulation performance compared to single-pane glass, and is gradually becoming one of the mainstream choices for architectural glass.

[0003] However, existing triple-glass, two-cavity glass still has the following technical defects: Insufficient thermal insulation performance: Some products use ordinary tempered glass without a low-emissivity coating, and the cavity is mostly filled with air, resulting in a high thermal conductivity. At the same time, the cavity support structure is mostly ordinary metal spacers (cold edge spacers), which are prone to forming thermal bridges, leading to a decrease in the cavity's thermal insulation effect and an increase in building energy consumption.

[0004] Poor sealing reliability: Traditional sealing structures are mostly single adhesive layers, which are prone to aging and cracking after long-term use, leading to air leakage and water vapor ingress into the cavity. This not only reduces the heat and sound insulation performance, but also causes condensation and fogging on the inner surface of the glass, affecting the performance.

[0005] Poor visual experience: The outer surface of tempered glass is prone to reflective glare, especially in strong light environments, which can affect indoor lighting comfort and the viewing effect of outdoor landscape.

[0006] Lack of edge protection: The edges of the glass are areas of stress concentration, and are prone to damage due to collisions and friction during transportation, installation and use, which reduces the product's service life.

[0007] Insufficient structural stability: Some products have unreasonable cavity thickness design or uneven distribution of support structure, resulting in poor overall flatness of the glass and easy deformation under long-term stress.

[0008] To address the aforementioned issues, there is an urgent need for a triple-glazed, double-cavity tempered glass with optimized structural design that balances energy efficiency, sealing, visual appeal, and protection, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0009] In view of the problems mentioned in the background art, the present invention aims to provide a triple-glazed, double-cavity tempered glass to solve the problems raised in the prior art.

[0010] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A triple-glazed, two-cavity tempered glass includes a first tempered glass, a second tempered glass, and a third tempered glass arranged in parallel in sequence. A first closed cavity is formed between the first tempered glass and the second tempered glass, and a second closed cavity is formed between the second tempered glass and the third tempered glass. The edges of the first tempered glass, the second tempered glass, and the third tempered glass are fixedly connected by a sealing structure, and both the first closed cavity and the second closed cavity are in a sealed state.

[0011] By adopting the above technical solution, this triple-glazed, double-cavity tempered glass, through the use of first tempered glass, second tempered glass and third tempered glass, forms a first closed cavity and a second closed cavity that can form a chamber, which greatly improves the heat insulation performance, strengthens the sealing reliability, extends the service life, provides excellent visual comfort, ensures structural stability and high safety.

[0012] Preferably, the first tempered glass, the second tempered glass, and the third tempered glass are all fully tempered glass.

[0013] By adopting the above technical solutions, fully tempered glass has high strength.

[0014] Preferably, the first and second enclosed cavities are filled with dry gas.

[0015] By adopting the above technical solution, the filling dry gas can improve the visual comfort of the glass.

[0016] Preferably, the sealing structure includes a spacer strip and a sealant layer. The spacer strip is respectively disposed at the edge position between the first tempered glass and the second tempered glass, and between the second tempered glass and the third tempered glass. The sealant layer covers the outside of the spacer strip.

[0017] By adopting the above technical solutions, the spacer strip and sealant layer can improve the sealing effect.

[0018] Preferably, the spacer is a warm-edge spacer.

[0019] By adopting the above technical solution, the warm edge spacer has a good insulation effect.

[0020] Preferably, the thickness of the first tempered glass, the second tempered glass and the third tempered glass is 3mm-12mm.

[0021] Preferably, the width of both the first enclosed cavity and the second enclosed cavity is 6mm-20mm.

[0022] Preferably, the outer surfaces of the first tempered glass and the third tempered glass are provided with functional coatings, wherein the functional coatings are Low-E coatings, UV-protective coatings, or privacy coatings.

[0023] In summary, the present invention has the following main advantages: The thermal insulation performance of this triple-glazed, double-cavity tempered glass is significantly improved: the combination design of low-emissivity tempered glass, high-concentration inert gas filling, and warm edge spacer makes the heat transfer coefficient K value of the glass ≤1.2W / (㎡・K), which is more than 30% lower than that of traditional triple-glazed, double-cavity glass. This can significantly reduce the energy consumption of building air conditioning and heating, and meet the green building standards.

[0024] This triple-glazed, double-cavity tempered glass boasts strong sealing reliability and a long service life: its double-sealing structure (butyl rubber + polysulfide rubber / silicone rubber) combines excellent air tightness, water tightness, and aging resistance, with a cavity leakage rate of ≤0.5% / year. This effectively prevents water vapor from entering, avoiding condensation and fogging on the glass, and the product's service life can reach more than 20 years.

[0025] This triple-glazed, double-cavity tempered glass offers excellent visual comfort: the anti-reflective coating on the outer surface reduces the glass surface reflectivity to ≤8% and the light transmittance to ≥85%, reducing glare interference under strong light, improving the uniformity of indoor lighting, and at the same time not affecting the observation of the outdoor landscape.

[0026] This triple-glazed, double-cavity tempered glass features a stable structure and high safety: the warm edge spacers are evenly distributed, and the cavity design with equal thickness ensures that the overall flatness error of the glass is ≤0.3mm / m; the safety performance of the tempered glass and the edge protection design with elastic corner protectors can effectively avoid the risk of breakage during use and improve product safety.

[0027] This triple-glazed, double-cavity tempered glass has a wide range of applications: the product takes into account multiple needs such as energy saving, safety, and comfort, and can be adapted to building exteriors, doors, windows, and curtain walls in different climate zones, as well as special scenarios such as rail transit and cold chain storage, making it highly practical.
