Abstract

The utility model discloses a double-layer vacuum glass, which comprises two pieces of glass 1 and 4 placed oppositely, vacuum sealant 3, a supporter 5 and an air sucked hole 2, wherein, the supporter 5 is arranged between the pieces of glass 1 and 4 to form a void. The periphery of the void is sealed by the vacuum sealant 3, and the air sucked hole 2 is arranged on the glass near the periphery position. The double-layer vacuum glass is provided with convection loss and sound intermediate, so the performances of thermal insulation and sound insulation can be improved. The utility model is particularly suitable for prior frame and the reform to old buildings.

Description

Dual-layer vacuum glass

The utility model relates to a kind of dual-layer vacuum glass, the dual-layer vacuum glass that particularly a kind of building uses.

In the prior art, on the door and window of building, brought into use a kind of double layer glass.But, be added with air layer in the middle of this double-layer glass, increased the loss of thermal convection current, and sound is to rely on material to propagate, air layer also is a sound bearing medium, has so just reduced the heat insulation and sound insulation property of double layer glass.In addition, the double layer glass thin and thick difference that existing market is sold, specification disunity.According to detection, when the intermediate layer of double layer glass was 18 millimeters, its insulation, sound insulation property were optimum value.If its thickness of hollow glass made from 5 millimeters glass is 28 millimeters, present window frame just can not use, and makes with new house design for old housing reform and brings difficulty.

The purpose of this utility model provides the dual-layer vacuum glass that a kind of insulation, sound insulation property are good, can use on building.

The utility model is to realize like this, this dual-layer vacuum glass comprises: two blocks of glass staggered relatively 1,4, vacuum compound 3, supporter 5 and aspirating hole 2, wherein, between glass 1 and 4, place supporter 5, to form the space between two blocks of glass 1,4, its periphery seals with vacuum compound 3, and aspirating hole 2 is arranged on the on glass of close periphery.The shape of supporter 5 can be a cylinder, and it highly is 0.2 to 0.25 millimeter, and holder 5 also can be a spheroid, and its diameter is 0.2 to 0.25 millimeter, and supporter 5 also can be a square, and length is 0.2 to 0.25 millimeter.

The utlity model has following advantage:

1. do not have convection losses owing to be evacuated between the dual-layer vacuum glass, improved heat-insulating property.

2. do not have sound bearing medium owing to be evacuated between the dual-layer vacuum glass, improved sound insulation property.

3. strength of glass is to rely on to add the supporter solution between two blocks of glass, so the intensity height.

4. use existing vacuum compound, solve the vacuum seal problem.

Above-mentioned purpose of the present utility model and other advantage will become clearer in detailed description in conjunction with the accompanying drawings, wherein,

Fig. 1 represents the generalized section of dual-layer vacuum glass of the present utility model.

Below in conjunction with accompanying drawing dual-layer vacuum glass of the present utility model is described in detail.As shown in Figure 1, dual-layer vacuum glass of the present utility model comprises: two glass staggered relatively 1,4, vacuum compound 3, supporter 5 and aspirating holes 2.Place supporter 5 between glass 1 and 4, to form two spaces between the glass, according to the detection contrast of different gap, when the dual-layer vacuum glass intermediate layer was 0.2 to 0.25 millimeter, the heat conduction sound insulation property was best.And supporter is when being 0.2 millimeter or 0.25 millimeter, and visual effect is people's acceptables, and heat conduction sound insulation has also reached satisfied effect.The shape of supporter 5 can be a cylinder, and it highly is 0.2 to 0.25 millimeter, also can be spheroid, and its diameter is 0.2 to 0.25 millimeter, also can be square, and length is 0.2 to 0.25 millimeter.The periphery of glass 1,4 seals with vacuum compound 3, and aspirating hole 2 is arranged on the on glass of close periphery.Can directly bleed with vacuum pump, the back of bleeding is stopped up with stopper, if vacuumize with vacuum tank then just do not have aspirating hole 2.Dual-layer vacuum glass thickness is that the thickness of two blocks of glass adds 0.2 (or 0.25) millimeter.For example, with 5 millimeters glass then vacuum glass thickness be the 5+5+0.2=10.2 millimeter, this specific character just is fit to the use of present window frame and the transformation of old building.
