Description

Technical Field

[0001] This utility model relates to the field of glass technology, and in particular to a fireproof and energy-saving vacuum glass. Background Technology

[0002] Vacuum glass is typically made by creating a vacuum between two panes of glass and then sealing the edges of the two panes with adhesive to form a composite glass.

[0003] The prior art discloses an energy-saving and fire-resistant composite glass (publication number: CN103883233A), characterized by including two pieces of Class C fire-resistant glass, fire-resistant heat insulation strip, fire-resistant sealant, and vacuum space.

[0004] In existing technologies, when assembling two pieces of glass to form composite glass, a sealant is required at the edges to form a seal. The sealing method is simple, and the sealant can only be formed after it solidifies, resulting in a long production cycle. Furthermore, controlling the spacing between the two pieces of glass and preventing them from shifting during the application of sealant is a challenge. Existing technologies have relatively weak optimization for the composite process of two pieces of glass, leaving room for improvement.

[0005] Therefore, we propose a fireproof and energy-saving vacuum glass. Utility Model Content

[0006] The present invention mainly solves the technical problem of inconvenience in applying adhesive when bonding the two pieces of glass, and provides a fireproof and energy-saving vacuum glass.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a fireproof and energy-saving vacuum glass, comprising:

[0008] Two glass plates are used to form a heat insulation cavity between them, and the edges of the two glass plates are filled with sealant.

[0009] A sandwich assembly is installed inside the insulation cavity to support two glass plates. The sandwich assembly includes a gasket, a side groove, and an expansion groove. The gasket forms a U-shaped frame. Expansion grooves are opened on both the top and bottom surfaces of the gasket. The top and bottom surfaces of the gasket each form two deformable petal-shaped structures through the side grooves. The two glass plates respectively abut against the top and bottom surfaces of the gasket. The outer wall of the gasket has discontinuous side grooves.

[0010] The protective structure is installed on the outside of the two glass plates to protect the edges and corners of the glass plates.

[0011] In a preferred embodiment of this utility model, the expansion groove forms a trapezoidal groove opening, the opening of the expansion groove gradually narrows from one end face of the washer to the other end face, and the expansion groove forms a closed rectangular groove. The top surface of the washer forms a petal-shaped structure on each side of the expansion groove, and the glass plate can abut against the petal-shaped structure and compress the petal-shaped structure to deform it.

[0012] In a preferred embodiment of this utility model, the side groove is formed into a wave-shaped groove, and several side grooves are opened on each of the four side walls of the glass plate, and the side grooves on the same side wall of the glass plate are not interconnected.

[0013] In a preferred embodiment of the present invention, the interlayer assembly further includes an air nozzle, which is fixedly connected to the gasket and extends from one side of the gasket to the other side.

[0014] In a preferred embodiment of the present invention, the protective structure includes an outer frame and a sealing plate. The outer frame forms a frame with an opening, and the outer frame is closed by the sealing plate and covers the edges of the two glass plates.

[0015] As a preferred embodiment of this utility model, the protective structure further includes a slot, the slot is formed on the inner wall of the outer frame, the outer frame forms a rectangular frame, the slot surrounds the inner wall of the outer frame, and the two glass plates are inserted into the slot.

[0016] As a preferred embodiment of this utility model, the protective structure further includes an anti-detachment groove, wherein the side wall of the outer frame is provided with an anti-detachment groove, and the sealing plate is embedded in the anti-detachment groove and locked to the outer frame with screws to close the opening of the outer frame.

[0017] In a preferred embodiment of this utility model, the sealing plate includes a rectangular plate, with an integrally formed circular plate at each end of the rectangular plate. The anti-detachment groove is used in conjunction with the sealing plate, and threaded holes are provided on the side wall of the outer frame.

[0018] Beneficial effects

[0019] This invention provides a fireproof and energy-saving vacuum glass. It has the following beneficial effects:

[0020] 1. This fireproof and energy-saving vacuum glass allows for the following process when assembling two glass plates: first, a gasket is placed on the lower glass plate, and then the other glass plate is placed on top. By squeezing the two glass plates, air in the expansion groove is expelled, allowing the gasket to adhere and fix to the glass plates. The two glass plates are positioned and fixed before the sealant solidifies, facilitating assembly. The side grooves on the outer wall of the gasket allow the sealant to penetrate during filling, increasing the contact area between the sealant and the gasket and improving adhesion. After the sealant solidifies, it forms a unified whole with the two glass plates and the gasket. The resulting composite glass has stronger integrity, better support for the edges of the glass plates, and is less prone to shifting during assembly, making it easier to control the distance between the two glass plates.

[0021] 2. This fireproof and energy-saving vacuum glass, by setting an air nozzle, allows for the connection of an air pump to evacuate the insulation cavity between two glass plates to create a vacuum. During assembly, after pressing the gasket between the two glass plates, the evacuation operation can begin. The pressure difference is used to press and fix the glass plates and gasket together, and then sealant is filled to form a composite glass, facilitating the assembly of the two glass plates. At the same time, the expansion groove causes the petal-shaped structure formed by the gasket to deform as the gas in the insulation cavity is discharged. The two glass plates compress the gasket, and the two petal-shaped structures, together with the sealant, form a triple-sealed barrier between the two glass plates, improving the insulation and sealing effect of the insulation cavity.

[0022] 3. This fireproof and energy-saving vacuum glass uses an outer frame to cover two glass panels. Stretching the outer frame expands its opening, allowing the two glass panels, after being filled with sealant, to be placed into the slot. The outer frame reduces the probability of the glass panels breaking due to impact at the corners, thus improving the protective effect.

[0023] 4. This fireproof and energy-saving vacuum glass, by embedding the sealing plate into the anti-detachment groove, uses screws to lock the sealing plate and the outer frame. The anti-detachment groove is the opening of the outer frame, so that the sealing plate can pull the opening of the outer frame to close tightly, so that the outer frame tightly covers the two glass plates. Multiple composite glass can be produced in the factory and then assembled with the window frame on the construction site, which improves the strength of the composite glass and the convenience of assembly.

[0030] A type of fireproof and energy-saving vacuum glass, such as Figure 1 As shown, it includes:

[0031] Two glass plates 10 form a heat-insulating cavity between them, and the edges of the two glass plates 10 are filled with sealant 11.

[0032] like Figure 2 and Figure 3 As shown, a sandwich assembly is installed inside the insulation cavity to support two glass plates 10. The sandwich assembly includes a gasket 12, side grooves 13, and expansion grooves 14. The gasket 12 forms a U-shaped frame, and expansion grooves 14 are formed on both the top and bottom surfaces of the gasket 12. The top and bottom surfaces of the gasket 12 each form two deformable petal-shaped structures through the side grooves 13. The two glass plates 10 respectively abut against the top and bottom surfaces of the gasket 12. The outer wall of the gasket 12 has discontinuous side grooves 13; the expansion grooves 14 are shaped like... The expansion groove 14 has a trapezoidal cross-section. The opening of the expansion groove 14 gradually narrows from one end of the washer 12 to the other end. The expansion groove 14 forms a closed rectangular groove. The top surface of the washer 12 forms a petal structure on each side of the expansion groove 14. The glass plate 10 can contact the petal structure and compress the petal structure to deform it. The side groove 13 forms a wavy groove. Several side grooves 13 are opened on each of the four side walls of the glass plate 10. The side grooves 13 on the same side wall of the glass plate 10 are not interconnected.

[0033] In this design, a refractory gasket 12 is used. The gasket 12 has a certain deformation capacity and can be made of refractory rubber. The gasket 12 separates the glass plate 10 to form an insulation cavity. A certain distance is left between the gasket 12 and the edge of the glass plate 10 for filling with sealant 11. The sealant 11 can be formed by applying adhesive. When the two glass plates 10 are laminated, the gasket 12 can be placed on the lower glass plate 10 first, and then the other glass plate 10 can be placed on top. By squeezing the two glass plates 10, the air in the expansion groove 14 is expelled. The gasket 12 can be adsorbed and fixed to the glass plate 10, positioning and fixing the two glass plates 10 before the sealant 11 solidifies, which facilitates the assembly of the two glass plates 10. When the sealant 11 is filled, the sealant 11 can penetrate into the side groove 13 on the outer wall of the gasket 12, thereby increasing the contact area between the sealant 11 and the gasket 12 and improving the adhesion effect. After the sealant 11 solidifies, it forms an integral whole with the two glass plates 10 and the gasket 12. The composite glass formed by the two glass plates 10 has stronger integrity and provides better support for the edges of the glass plates 10.

[0034] The sandwich assembly also includes an air nozzle 15, which is fixedly connected to the gasket 12. The air nozzle 15 extends from one side of the gasket 12 to the other side. The air nozzle 15 can be a one-way valve. By setting the air nozzle 15, a vacuum pump can be connected to the air nozzle 15 to evacuate the heat insulation cavity between the two glass plates 10 to form a vacuum. During assembly, the two glass plates 10 are pressed together with the gasket 12, and the air evacuation operation can be carried out. The pressure difference is used to press and fix the glass plates 10 and the gasket 12 tightly. Then, the sealant 11 is filled to form a composite glass, which facilitates the assembly of the two glass plates. At the same time, the expansion groove 14 causes the petal structure formed by the gasket 12 to deform as the gas in the heat insulation cavity is discharged. The two glass plates 10 squeeze the gasket 12, causing the petal structure of the gasket 12 to deform. The two petal structures, together with the sealant 11, form a triple sealing barrier between the two glass plates 10, improving the heat insulation and sealing effect of the heat insulation cavity.

[0035] like Figure 4 and Figure 5 As shown, the protective structure is installed on the outside of the two glass plates 10 to protect the edges and corners of the glass plates 10.

[0036] The protective structure includes an outer frame 20 and a sealing plate 21. The outer frame 20 forms a frame with an opening. The outer frame 20 is closed by the sealing plate 21 and covers the edges of the two glass plates 10. The protective structure also includes a slot 23. The slot 23 is opened on the inner wall of the outer frame 20. The outer frame 20 forms a rectangular frame. The slot 23 surrounds the inner wall of the outer frame 20. The two glass plates 10 are inserted into the slot 23.

[0037] In this solution, considering that the two glass plates 10 after composite are easily broken when impacted, the two glass plates 10 are covered by the outer frame 20. The outer frame 20 is stretched to expand the opening of the outer frame 20, and the two glass plates 10 filled with sealant 11 are placed into the slot 23. The outer frame 20 can reduce the probability of the glass plates 10 breaking due to impact at the corners, thus improving the protection effect.

[0038] like Figure 5 As shown, the protective structure also includes an anti-detachment groove 22. The anti-detachment groove 22 is opened on the side wall of the outer frame 20. The sealing plate 21 is embedded in the anti-detachment groove 22 and locked to the outer frame 20 with screws to close the opening of the outer frame 20. The sealing plate 21 includes a rectangular plate, and each end of the rectangular plate is provided with an integrally formed circular plate. The anti-detachment groove 22 and the sealing plate 21 are used in conjunction with each other. The side wall of the outer frame 20 is provided with a threaded hole. By embedding the sealing plate 21 into the anti-detachment groove 22, the sealing plate 21 and the outer frame 20 are locked with screws. The anti-detachment groove 22 is the opening of the outer frame 20. Thus, the sealing plate 21 can pull the opening of the outer frame 20 tight and close it, so that the outer frame 20 tightly covers the two glass plates 10 and forms armor. Multiple composite glass can be produced in the factory and then assembled with window frames on the construction site, which improves the strength of the composite glass and the convenience of assembly.

[0039] The working principle of this utility model is as follows: A certain distance is left between the gasket 12 and the edge of the glass plate 10 for filling with sealant 11. The sealant 11 can be formed by applying glue. When the two glass plates 10 are laminated, the gasket 12 can be placed on the lower glass plate 10 first, and then the other glass plate 10 can be placed on top. By squeezing the two glass plates 10, the air in the expansion groove 14 is expelled, and the gasket 12 can be adsorbed and fixed to the glass plate 10. The air pump connected to the air nozzle 15 is used to clean the space between the two glass plates 10. The hot cavity is evacuated to form a vacuum. During assembly, the two glass plates 10 are pressed together with the gasket 12, and the evacuation operation can be carried out. The pressure difference is used to press and fix the glass plates 10 and the gasket 12 tightly. Then, the sealant 11 is filled to form a composite glass. The expansion groove 14 causes the petal structure formed by the gasket 12 to deform as the gas in the heat insulation cavity is discharged. The two glass plates 10 squeeze the gasket 12, causing the petal structure of the gasket 12 to deform. The glass plates 10 and the gasket 12 are tightly attached. The two petal structures, together with the sealant 11, form multiple sealing rings.

[0040] Stretching the outer frame 20 expands its opening, allowing the two glass plates 10 filled with sealant 11 to be placed into the slot 23. The sealing plate 21 is embedded in the anti-detachment groove 22, and the sealing plate 21 and the outer frame 20 are locked together with screws. The anti-detachment groove 22 is where the opening of the outer frame 20 is made, so that the sealing plate 21 can pull the opening of the outer frame 20 closed tightly, making the outer frame 20 tightly cover the two glass plates 10.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
