Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass-related technology, and in particular relates to an insulated glass structure that combines laminated glass to enhance the structure, improve the overall quality, extend the effective service life, and increase energy-saving and carbon-reduction effects. Background Technology
[0002] For common buildings, installing glass as windows and walls is a basic architectural technique. The differences lie only in the location, shape, size, quantity, and materials of the glass. Early designs used ordinary transparent glass without considering functions other than lighting. However, after long-term use, it was found that ordinary glass had significant shortcomings in terms of sound insulation, heat insulation, and earthquake resistance, making it difficult to meet the needs of living or working, and thus necessitating improvements.
[0003] Insulating glass is a composite glass product consisting of two or more glass panes separated by aluminum alloy or butyl rubber spacers and sealed with sealant to form a hollow interlayer. The hollow interlayer is either evacuated or filled with an inert gas (such as argon). This process significantly improves the sound insulation, heat insulation, airtightness, watertightness, and safety of insulating glass. It also offers advantages such as energy saving, carbon reduction, maintenance-free operation, and long lifespan, making it a highly practical and ideal building material.
[0004] However, although insulated glass is already quite practical, the glass itself cannot avoid the possibility of spontaneous breakage. The spontaneous breakage of glass installed on high-rise buildings may pose potential risks to the personal safety of vehicles and pedestrians on the ground, as well as property such as vendors. The solution is usually to add laminated glass to the outside of the insulated glass. However, traditional laminated glass does not have a long service life. The laminated glass itself may delaminate due to thermal expansion and contraction and the entry of moisture, or it may delaminate after a period of time due to poor processing. This will seriously affect the safety performance of the glass in high-rise buildings, or the thermal insulation and energy-saving performance of the insulated glass.
[0005] To address the aforementioned shortcomings, selecting suitable energy-saving and carbon-reducing laminated glass building materials is the optimal choice to improve the long-term performance of insulated glass.
[0006] Laminated glass is a type of glass in which a polyvinyl butyral resin (PVB) film is sandwiched between two or more glass substrates. The glass substrates and the PVB film are bonded together under high temperature and pressure. The high elasticity and toughness provided by the PVB film strengthen the overall structure of the laminated glass. Because it has high wind resistance, noise reduction, heat insulation and shock absorption functions, it is particularly suitable for use in the structure of insulated glass.
[0007] However, due to the inherent structure of laminated glass, there are bound to be gaps between the glass substrate and the PVB film. After long-term exposure to sun and rain, these gaps will expand due to thermal contraction or aging, increasing the chance of moisture penetration. This not only damages the adhesion between the glass substrate and the PVB film, but also reduces the light transmittance, heat insulation, and sound insulation of the laminated glass, thus affecting its safety and service life.
[0008] This shows that the conventional insulated glass structure still has shortcomings and cannot achieve its best performance, and therefore urgently needs to be improved.
[0009] The creator of this project embarked on research and development, and through improvements to the structural design of the glass panel, proposed a practical product improvement plan. Through repeated research and implementation, the insulated glass structure of this laminated glass was finally completed. Utility Model Content
[0010] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a laminated glass insulated glass structure that uses long-life laminated glass as the glass panel option, which can improve the structural strength of the insulated glass, not only fulfilling the function of the insulated glass, but also significantly extending its service life.
[0011] Another objective of this invention is to provide a laminated glass insulated glass structure that can reduce the frequency of replacing and maintaining insulated glass in buildings, effectively reduce usage costs, and thus achieve the goals of energy conservation, carbon reduction, environmental protection, and love for the Earth.
[0012] Another objective of this invention is to provide a laminated glass insulated glass structure that can reduce waste generated during the production and replacement of insulated glass, reduce energy waste and environmental pollution, and achieve energy conservation and carbon reduction.
[0013] An insulating glass structure for laminated glass that can achieve one of the aforementioned objectives includes: A laminated glass insulated glass structure, comprising: Two glass panels are stacked on top of each other, wherein at least one of the glass panels is laminated glass; A spacer is disposed between the two glass plates and surrounds the area around the two glass plates, so that there is a space between the two glass plates and the spacer, the space being either sealed or filled with an inert gas.
[0014] The glass panel consists of two or more stacked pieces. The glass panel is made of ordinary glass or laminated glass, and a spacer is provided between any two adjacent glass panels.
[0015] Furthermore, the laminated glass includes: At least two glass substrates are stacked on top of each other, and an interlayer space is provided between any two adjacent glass substrates, forming a closed state within the interlayer space; A sealing edge is provided within the interlayer space and surrounds the area around the glass substrate.

[0016] Preferably, the spacer has an outer structural layer and an inner sealing layer.
[0017] Preferably, the inert gas is argon, krypton, xenon, or sulfur hexafluoride.
[0018] The beneficial effects of this utility model are as follows: 1. The space is sealed or filled with inert gas, which is intended to improve the heat insulation effect of the insulating glass 10 and make it less likely to react with light, thus maintaining the sound insulation, heat insulation and airtightness of the insulating glass 10. 2.

Using more glass panels can increase the thickness and strength, and improve functions such as windproof, noise reduction, heat insulation and shock absorption. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0022] Please see Figures 1 to 6 As shown, this utility model provides a laminated glass insulated glass structure, particularly a structurally stable insulated glass 10 that can be used effectively for a long time, which includes at least two glass plates 100 and a spacer 200.
[0023] The glass panels 100 are stacked on top of each other and can be ordinary glass or other tempered glass, but at least one or all of the glass panels 100 are laminated glass. The spacer 200 is disposed between the two glass plates 100 and surrounds the area around the two glass plates 100, so that there is a space 400 between the two glass plates 100 and the spacer 200. The space 400 is either sealed or filled with inert gas, the purpose of which is to improve the heat insulation effect of the insulated glass 10.
[0024] In the aforementioned design, the spacer 200 has an outer structural layer 210 and an inner sealing layer 220. The structural layer 210 provides structural strength to the insulated glass 10 after molding, such as a metal like aluminum alloy, or a non-metal like plastic or rubber with sufficient strength. The sealing layer 220 mainly maintains the airtightness of the space 400 and can be an adhesive structure such as butyl rubber or polyisobutylene rubber (PIB).
[0025] In addition, the inert gas filled in the space 400 is argon, krypton, xenon, or sulfur hexafluoride, which does not easily react with light, thus maintaining the sound insulation, heat insulation, and airtightness of the insulating glass 10.
[0026] The insulating glass 10 structure of this utility model, completed by the aforementioned components, not only effectively maintains its airtightness, but also significantly improves the structural strength of the insulating glass 10, enabling it to function under long-term exposure to wind and sun, reducing maintenance troubles and costs, and extending its service life.
[0027] Please see Figure 4 As shown, this utility model uses laminated glass for at least one of the glass plates 100, and its structure includes: At least two glass substrates 110 are stacked on top of each other, and an interlayer space 120 is provided between any two adjacent glass substrates 110, forming a closed state within the interlayer space 120. A sealing edge 130 is disposed within the interlayer space 120 and surrounds the area around the glass substrate 110, thereby sealing the interlayer space 120. The adhesive film layer 140 is disposed within the interlayer space 120 inside the sealing edge 130; Each of the glass substrates 110, the sealing edge 130, and the adhesive film layer 140 is sealed and formed after being subjected to high temperature and pressure.
[0028] The glass panel 100 formed from the aforementioned laminated glass has a sealing edge 130, which is mainly an adhesive structure of butyl rubber or polyisobutylene rubber, used to seal each of the glass substrates 110, maintain the airtightness of the interlayer space 120, and prevent moisture from entering and affecting its function. The adhesive film layer 140 is an adhesive structure of polyvinyl butyral resin (PVB), used to seal each of the glass substrates 110. It has high elasticity and toughness, and provides functions such as windproof, noise reduction, heat insulation, and shock absorption. In this way, the sealing edge 130 and the adhesive film layer 140 strengthen the overall structure of the laminated glass panel 100 after it is formed, greatly increasing the effectiveness of the glass panel 100 and its long service life.
[0029] For further information, please refer to Figure 5 , Figure 6 As shown, in addition to the aforementioned use of two glass plates 100 stacked together, the present invention can also provide two or more glass plates 100 stacked together. Similarly, the newly added glass plates 100 are ordinary glass or laminated glass, and corresponding spacers 200 are provided between any two adjacent glass plates 100 to form a complete insulated glass 10 structure. Using more glass plates 100 can increase the thickness and strength, and improve functions such as windproof, noise reduction, heat insulation and shock absorption, so as to adapt to more different application fields.
