Description

Technical Field

[0001] This application relates to glass curtain walls, and more particularly to a low-emissivity glass curtain wall. Background Technology

[0002] As a core component of the exterior envelope of modern buildings, building curtain walls undertake basic functions such as lighting, ventilation, and protection. At the same time, their performance directly affects the building's energy efficiency and indoor environmental quality. With the continuous improvement of the construction industry's requirements for green environmental protection and energy conservation, curtain walls have evolved from simple functional components to integrated systems with multiple characteristics such as energy saving, environmental protection, and comfort. Their role in reducing building energy consumption and improving the living environment is becoming increasingly prominent.

[0003] However, existing glass curtain walls have significant shortcomings in radiation control. Traditional glass curtain walls, lacking targeted radiation blocking design, have a high transmittance of infrared and ultraviolet rays from solar radiation. This not only causes a large amount of heat to accumulate in the building interior during the summer, increasing the energy consumption of the air conditioning system, but also damages indoor furniture and decorative materials due to long-term ultraviolet radiation, and may even have adverse effects on human health.

[0004] To address the aforementioned issues, this application aims to provide a low-emissivity glass curtain wall. Through innovative coating technology and structural design, it effectively reduces the transmittance of infrared and ultraviolet rays, significantly improving radiation blocking performance, thereby solving the problem of excessive radiation from traditional glass curtain walls and providing a new technical solution for building energy conservation and indoor environment improvement. Utility Model Content The purpose of this application is to provide a low-emissivity glass curtain wall with advantages such as high radiation resistance, thus solving the problem of high radiation levels.

[0005] The low-emissivity glass curtain wall provided in this application adopts the following technical solution: it includes a supporting structure, a glass substrate and a cavity module. The glass substrate is disposed within the supporting structure, and the cavity module is located between the glass substrates. The glass substrate includes two sets of glass bodies.

[0006] By adopting the above technical solution, through the combination of support structure, glass substrate and cavity module, and by utilizing the cooperation of two sets of glass bodies and cavity modules, an overall synergistic low-emissivity structural system is formed. It can effectively block infrared and ultraviolet rays through the low-emissivity characteristics of the glass substrate, enhance the thermal insulation effect with the help of cavity modules, and achieve stable fixation through the support structure.

[0007] Preferably, the glass substrate includes a self-cleaning layer, a bottom layer, a silver layer, and a barrier layer. The bottom layer, the silver layer, and the barrier layer are sequentially disposed on the inner surface of the glass body, and the self-cleaning layer is disposed on the outer surface of the glass body.

[0008] By adopting the above technical solution, a base layer, a silver layer, and a barrier layer are sequentially set on the inner side, and a self-cleaning layer is set on the outer side. The self-cleaning layer can achieve self-cleaning by using natural light, reducing maintenance costs and keeping the appearance clean. The multi-layer coating structure on the inner side can specifically reflect infrared and ultraviolet rays while ensuring visible light transmission. This improves low-radiation performance, protects indoor furniture and decorations from ultraviolet damage, and improves the indoor environment.

[0011] Preferably, the support structure includes a frame, a sealing plate, a first reinforcing rib, and a second reinforcing rib. The frame is arranged around the outer periphery of the sealing frame, the sealing plate is connected to the inner side of the frame, and the first reinforcing rib and the second reinforcing rib are respectively arranged at the top and bottom of the frame.

[0012] By adopting the above technical solution, the frame is set around the sealing frame, and the sealing plate is used to achieve a stable wrapping of the glass substrate and cavity module. The first and second reinforcing ribs at the top and bottom can enhance the overall strength of the supporting structure and improve the curtain wall's resistance to wind pressure and deformation.

[0013] Preferably, a sealing groove is provided on one side of the frame, and a screw hole is provided at one end of the surface of the first reinforcing rib and the second reinforcing rib, and the sealing groove is adapted to the sealing plate.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This low-emissivity glass curtain wall, through the combination of a supporting structure, glass substrate, and cavity modules, utilizes the cooperation of two sets of glass bodies and cavity modules to form an integrated and synergistic low-emissivity structural system.

The glass substrate 2 is disposed within the support structure 1, and the cavity module 3 is located between the glass substrates 2. The glass substrate 2 includes two sets of glass bodies 201. Through the combination of the support structure 1, the glass substrate 2, and the cavity module 3, the two sets of glass bodies 201 and the cavity module 3 cooperate to form an overall synergistic low-emissivity structural system. It can effectively block infrared and ultraviolet rays through the low-emissivity characteristics of the glass substrate 2, and enhance the thermal insulation effect with the help of the cavity module 3. At the same time, it can be stably fixed through the support structure 1.

[0026] Example 2: A low-emissivity glass curtain wall, referring to Figure 2 and Figure 3The glass substrate 2 includes a self-cleaning layer 202, a bottom layer 203, a silver layer 204, and a barrier layer 205. The bottom layer 203, silver layer 204, and barrier layer 205 are sequentially disposed on the inner surface of the glass body 201, and the self-cleaning layer 202 is disposed on the outer surface of the glass body 201. By sequentially disposing of the bottom layer 203, silver layer 204, and barrier layer 205 on the inner surface and the self-cleaning layer 202 on the outer surface, the self-cleaning layer 202 can achieve self-cleaning using natural light, reducing maintenance costs and maintaining a clean appearance. The multi-layer coating structure can selectively reflect infrared and ultraviolet rays while ensuring visible light transmission. This improves low-emissivity performance, protects indoor furniture and decorations from UV damage, and improves the indoor environment. The cavity module 3 includes a sealing frame 301, a cavity 302, a partition 303, and sealant 304. The sealing frame 301 surrounds the edge of the glass substrate 2. The cavity 302 is formed within the space enclosed by the sealing frame 301 and the glass substrate 2. The partition 303 is disposed within the cavity 302, and the sealant 304 fills the cavity. The sealing frame 301 and the glass substrate 2 are connected by a sealing plate 303 filled with desiccant. The sealing frame 301 and the sealant 304 work together to effectively seal the edge of the glass substrate 2, ensuring the airtightness and watertightness of the cavity 302. The partition plate 303 separates the cavity 302 and contains desiccant, which can absorb moisture in the cavity, avoid the impact of moisture on the curtain wall performance, and ensure the service life of the curtain wall. The supporting structure 1 includes a frame 101, a sealing plate 102, a first reinforcing rib 104, and a second reinforcing rib 106. The frame 101 is arranged around the outer periphery of the sealing frame 301, and the sealing plate 102 is connected to the inner side of the frame 101. The first reinforcing rib 104 and the second reinforcing rib 106 are respectively arranged at the top and bottom of the frame 101. The frame 101 is arranged around the sealing frame 301, and together with the sealing plate 102, it can stably wrap the glass substrate 2 and the cavity module 3. The first reinforcing rib 104 and the second reinforcing rib 106 at the top and bottom can enhance the overall strength of the supporting structure 1 and improve the wind pressure resistance and deformation resistance of the curtain wall.

[0027] Example 3: A low-emissivity glass curtain wall, referring to Figure 3 and Figure 4A sealing groove 105 is provided on one side of the frame 101. Screw holes 107 are provided at one end of the surfaces of the first reinforcing rib 104 and the second reinforcing rib 106. The sealing groove 105 is adapted to the sealing plate 102. This adaptation allows multiple frames 101 to be spliced ​​together. The first reinforcing rib 104 and the second reinforcing rib 106 can firmly fix the spliced ​​frames 101. A temperature sensor 103 is provided on the support structure 1. The temperature sensor 103 is connected to an internal display. This allows for real-time monitoring of temperature changes inside and outside the curtain wall, providing data support for evaluating the curtain wall's operational status and energy-saving control, facilitating timely adjustments to usage strategies. The bottom layer 203 is a silicon oxide layer, the silver layer 204 is a silver layer, and the barrier layer 205 is... A titanium oxide layer, a bottom layer 203, a silver layer 204, and a barrier layer 205 are stacked sequentially from the surface of the glass body 201 outwards. The bottom layer 203 is made of silicon oxide, the silver layer 204 is a silver layer, and the barrier layer 205 is a titanium oxide layer, and these layers are stacked sequentially. The silicon oxide bottom layer 203 can enhance the adhesion strength between the coating and the glass body 201. The silver layer can efficiently reflect infrared and ultraviolet rays in solar radiation. The titanium oxide barrier layer 205 can protect the silver layer 204 from the influence of the external environment, ensure the service life of the coating, and ensure the long-term stability of low-emissivity performance. The partition 303 divides the cavity 302 into multiple chambers, which are filled with inert gas. The low thermal conductivity of the inert gas further enhances the thermal insulation effect of the cavity 302, reduces the heat exchange between the interior and exterior of the building, and reduces the energy consumption of air conditioning and other equipment.

[0028] The implementation principle of this application embodiment is as follows: When the low-emissivity glass curtain wall is in use, the frame 101 of the support structure 1 surrounds the outer periphery of the sealing frame 301 to form a stable support. Combined with the fit between the sealing plate 102 and the sealing groove 105, this ensures reliable fixation of the glass substrate 2 and the cavity module 3, while also enhancing overall sealing and reducing heat exchange caused by air convection. The first reinforcing rib 104 and the second reinforcing rib 106 at the top and bottom improve the curtain wall's resistance to wind pressure and deformation, ensuring structural stability in different environments. The screw holes 107 on the reinforcing ribs facilitate connection and fixation with the building structure, ensuring overall robustness after installation. The two sets of glass bodies 201 of the glass substrate 2 form the basic structure. The outer self-cleaning layer 202 can decompose surface dirt under natural light, maintaining a clean appearance without frequent manual cleaning and reducing maintenance costs. The inner bottom layer 203, silver layer 204, and barrier layer 205, layered sequentially, work together to achieve low-emissivity. The silicon dioxide base layer 203 enhances the adhesion strength between the coating and the glass body 201. The silver layer can efficiently reflect infrared and ultraviolet rays in solar radiation, reducing indoor heat accumulation and UV damage to furniture and decorations. The titanium dioxide blocking layer 205 protects the silver layer 204 from external environmental corrosion, ensuring long-term stability of low-emissivity performance. At the same time, the multi-layer coating structure ensures good visible light transmission, meeting the indoor natural lighting needs. The sealing frame 301 and sealant 304 work together to seal the edge of the glass substrate 2, effectively blocking air and moisture penetration and ensuring the airtightness and watertightness of the cavity 302. The cavity 302 is divided into multiple independent chambers by the partition 303. The inert gas filled inside further enhances the thermal insulation effect due to its low thermal conductivity, reducing indoor and outdoor heat exchange and reducing the energy consumption of air conditioning and other equipment. The desiccant in the partition 303 continuously adsorbs moisture in the cavity, avoiding condensation or performance degradation caused by excessive humidity and ensuring the service life of the curtain wall.
