Description

Technical Field

[0001] The utility model belongs to the field of glass, and particularly relates to a laminated insulating glass. Background Art

[0002] Laminated glass is composed of two or more pieces of glass, with a functional film arranged between the glasses. The above structure forms an integral body after being processed by a high-temperature and high-pressure process; in some products, a gap is added between adjacent glasses to form a middle control layer for obtaining heat insulation and sound insulation functions. In such a hollow structure, an outer frame is required to fix the glass. The sound insulation function is popular in the market. The prior art "CN217598014U - A color-changing laminated glass" discloses a scheme with two internal vacuum sound insulation cavities. Although the sound insulation function is achieved, the sealing ability of the protective sleeve is limited, and the vacuum sound insulation cavity will gradually fail after a long time. Similar problems also exist in the vacuum sound insulation cavities of other glasses on the market. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a laminated insulating glass with good sound insulation effect.

[0004] To achieve the above purpose, the utility model provides a laminated insulating glass, including: a first glass, a second glass, and a frame surrounding the four sides of the first glass and the second glass. The frame is provided with grooves for clamping the glass on the side fitting the glass. There are raised ridges between adjacent two grooves, and the thickness of the ridges is equal to the distance between the first glass and the second glass. Glue for fixing is arranged between the first glass and the grooves and between the second glass and the grooves. The frame includes four side frames with the same cross-section. The end faces between adjacent two side frames are provided with 45° chamfers. The ridges between adjacent side frames are attached to each other. Step holes are arranged at the ends of each pair of adjacent ridges, and bolt groups are arranged in the step holes to gather the adjacent ridges.

[0005] As an improvement of the above scheme, an exhaust hole is arranged on one of the ridges. The exhaust hole communicates with the outside and the space between adjacent two glasses at both ends. A one-way valve is arranged in the exhaust hole and is used to connect a pumping device, so as to form a vacuum sound insulation cavity between the first glass and the second glass.

[0006] As an improvement of the above scheme, the first glass faces outdoors, the second glass faces indoors, a sunscreen film is arranged on the inner side of the first glass, and an explosion-proof film is arranged on the inner side of the second glass.

[0007] As an improvement of the above scheme, an endothermic phase change coating is arranged on the surface of the ridge.

[0008] As an improvement of the above solution, the thickness of the rib is 8-12 mm, the thickness of the first glass and the second glass is 6-9 mm, and the depth of the groove is 4-5 mm.

[0009] As an improvement of the above solution, the frame is made of PC material, PVC material or elastic rubber material.

[0010] The utility model has the following beneficial effects: The glass is clamped by the frame, and the frame is reinforced by the bolt group, which is more stable than the traditional pasting and fixing method, and the gap between the edge of the glass and the inner side of the frame is greatly reduced. On this basis, this solution can stably maintain the vacuum sound insulation cavity between adjacent glasses, and after adding films with different functions to the glass, the functions of this solution are further enriched.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The embodiments of the present utility model will be described below according to its overall structure.

[0017] Referring to Figure 1 and Figure 2 , the present utility model discloses a sandwich insulating glass, comprising: a first glass 21, a second glass 22, and a frame surrounding the peripheries of the first glass 21 and the second glass 22. Both the first glass 21 and the second glass 22 are rectangular, and correspondingly, the frame is also rectangular. The frame is provided with grooves for clamping the glass on the side in contact with the glass, and there are raised ribs 23 between adjacent two grooves. The thickness of the rib 23 is equal to the spacing between the first glass 21 and the second glass 22. Glue for fixing is provided between the first glass 21 and the groove and between the second glass 22 and the groove. The frame comprises four side frames 10 with the same cross-section. The end faces between adjacent two side frames 10 are provided with 45° chamfers. The ribs 23 between adjacent side frames 10 are in contact with each other. A stepped hole is provided at the end of each pair of adjacent ribs 23, and a bolt group 31 is arranged in the stepped hole. The bolt group 31 gathers the adjacent ribs 23. By adopting the above solution, the position of the stepped hole makes full use of the structure of the relatively thick rib 23, which is convenient for drilling and can also bear force.

[0018] As an improvement of the above solution, an exhaust hole 32 is provided on one of the ribs 23. The exhaust hole 32 communicates with the outside and the space between adjacent two glasses at both ends. A one-way valve is arranged in the exhaust hole 32 and is used to connect an air extraction device, so that a vacuum sound insulation cavity is formed between the first glass 21 and the second glass 22, and good sound insulation effect is achieved by using the vacuum. After removing the air extraction device, the exhaust hole 32 has an automatic blocking effect.

[0019] As an improvement of the above solution, the first glass 21 faces outdoors, the second glass 22 faces indoors. A sunscreen film 41 is arranged on the inner side of the first glass 21. At this time, the heat and ultraviolet rays of direct sunlight are mainly adsorbed by the sunscreen film 41. An explosion-proof film 42 is arranged on the inner side of the second glass 22, which is used to prevent the glass from shattering and scattering indoors, reducing potential safety hazards.

[0020] As an improvement of the above solution, a heat-absorbing phase-change coating is provided on the surface of the rib 23. With the above solution, the heat-absorbing phase-change coating is used to maintain the temperature stability of the vacuum sound insulation cavity and reduce the degree of thermal deformation of related components.

[0021] As an improvement of the above solution, the thickness of the rib 23 is 8-12 mm, the thicknesses of the first glass 21 and the second glass 22 are 6-9 mm, and the depth of the groove is 4-5 mm.

[0022] As an improvement of the above solution, the frame is made of PC material, PVC material or elastic rubber material.

[0023] The glass is clamped by the frame, and the border 10 is reinforced by the bolt group 31, which is more stable than the traditional pasting and fixing method, and the gaps between the edges of the glass and the inner side of the frame are greatly reduced. On this basis, this solution can stably maintain the vacuum sound insulation cavity between adjacent glasses, and after adding films with different functions to the glass, the functions of this solution are further enriched.
