Description

A kind of hollow glass

Technical field

The utility model relates to the building glass field, relates in particular to a kind of improvement of hollow glass.

Background technology

Along with the progressively raising of living standards of the people, also more and more higher to the comfort level requirement of dwelling house, will increase heating and air conditioner facility, building energy consumption will increase considerably, and the proportion of building energy consumption account total energy consumption also can be increasing.Especially northern China cities and towns heating energy consumption, large public building energy consumption and Yangtze river basin heating energy consumption will make China's building energy conservation situation severe more.Therefore, building energy conservation is that China guarantees national energy security and the important behave of building economy type and friendly environment society.China Ministry of Construction has issued " civilian construction energy-saving design standard ", " Xia Redong cryogenic region energy Saving Design of Residential Buildings standard ", " hot summer and warm winter region Residential Buildings Energy standard " and national standards such as " public building energy-saving design standards " successively, has covered the civilian construction of the different weathers of China.To the year two thousand twenty, the north and coastal economy developed regions and megalopolis new building will be realized energy-conservation 65% target, certainly will widely popularize energy saving building glass.

The architectural energy consumption of current China comprises the production of constructional materials, and air-conditioning, ventilation, illumination, hot water, household electrical appliances etc. reached more than 30% of primary energy consumption at interior total energy consumption, occupies the first place of energy consumption.For building trade, the thermal insulation level of fence is most important, is related to the efficient of air-conditioning, heating, and adopting high performance heat insulating material is the critical path that reduces energy consumption.The modern architecture daylighting area is increasing, it is increasing that wherein door and window accounts for the proportion of fence, its energy-saving heat-insulating level is directly connected to the height of whole building energy-saving index, the hollow glass that the curtain wall of existing building adopts inside and outside two sheet glass to make mostly, obviously, only plate low-radiation film on the cavity face of hollow glass, its heat-proof quality and sound insulation value can not satisfy the requirement of high-end user.

The utility model content

The purpose of this utility model is to overcome the defective of prior art, and the hollow glass of a kind of U of reduction value, raising soundproof effect is provided.

The utility model is achieved in that a kind of hollow glass, comprises two sheet glass that be arranged in parallel, isolates by spacer bar between described two sheet glass, and described two sheet glass respectively are covered with the low-radiation film layer on opposed.

Further, the periphery of described low-radiation film layer is through polishing 10 millimeters-55 millimeters.

Further, be coated with butyl rubber on the contact surface of described spacer bar and described two sheet glass, described spacer bar periphery is coated with fluid sealant, to form a closed cavity.

Further, be filled with inert gas in the described closed cavity.

Further, described hollow spacer bar is aluminium spacer bar or stainless steel spacer bar or the warm limit spacer bar that inside is filled with molecular sieve desiccant.

The utlity model has following technique effect:

Two sheet glass described in the utility model are covered with the low-radiation film layer on opposed, can be so that hollow glass have better coefficient of heat insulation, and its U value can be reduced to 0.8～1.2W/m ²K can improve sound insulation value to 20～26dB, can both satisfy the demand of high-end user on heat-proof quality and sound insulation value.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment hollow glass.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Referring to Fig. 1, the utility model embodiment provides a kind of hollow glass 1, comprises two sheet glass that be arranged in parallel, isolates by spacer bar between described two sheet glass, and described two sheet glass are covered with low-radiation film layer 12 on opposed.Like this, can be so that hollow glass 1 have better coefficient of heat insulation, its U value can be reduced to 0.8～1.2W/m2K, can improve sound insulation value to 20～26dB, can both satisfy the demand of high-end user on heat-proof quality and sound insulation value.

In the utility model specific embodiment structure, the periphery of described low-radiation film layer 12 is through polishing 10 millimeters-55 millimeters, and described low-radiation film layer 12 passes through the mode of mask or mechanical grinding to polish, like this, and with convenient sealing two sheet glass.What need slightly explain is, two sheet glass are that inner layer glass 13 and glass outer 14 combine, and certainly, at some special dimensions, hollow glass 1 also can be made up of three, four layers or compound glass; Wherein, described inner layer glass 13 and described glass outer 14 thickness are 5 millimeters-10 millimeters, and are a kind of tempered glass, can be behind the first tempering behind plated film or the first plated film tempering handle, hardness, stability are better after processing like this.

Further,, separate by spacer bar 16, and support inner layer glass 13 and glass outer 14 at inner layer glass 13 and glass outer 14 referring to Fig. 1; 13,14 of spacer bar 16 and internal and external layers of glass are coated with butyl rubber (not shown), fixedly inner layer glass 13 and glass outer 14 and spacer bar 16; Described inner layer glass 13, glass outer 14, spacer bar 16 form a closed cavity, particularly, described spacer bar 16 is aluminium spacer bar or stainless steel spacer bar or warm limit spacer bars that inside is filled with molecular sieve desiccant, be filled with desiccant in the spacer bar 16, spacer bar 16 is aperture towards the face of fluid sealant, can absorb steam, to guarantee the drying of the inert gas in the cavity by fluid sealant 11.

Referring to Fig. 1, described fluid sealant 11 is used to seal the two ends of described inner layer glass 13, described glass outer 14, wherein said fluid sealant 11 can be silicone sealant or polysulfide sealant, fluid sealant 11 can link together described inner layer glass 13, described glass outer 14, and and having formed an enclosure space between the described inner layer glass 13, described glass outer 14, the thickness in this space is 6 millimeters-20 millimeters.

Further, referring to Fig. 1, in the utility model specific embodiment structure, be filled with inert gas 15 in the closed cavity that described inner layer glass 13, glass outer 14, spacer bar 16 form, described inert gas 15 is argon gas or xenon, therefore relatively stable, the torpescence and littler than air heat conduction of argon gas or xenon performance replaces air with this.

What need be illustrated is that in the present embodiment, described low-radiation film layer 12 can be high-transparency low-radiation film, sunshade type low-radiation film or the two silver low radiation film that the off-line magnetron sputtering method is coated with, perhaps online low-radiation film.

The above only is the utility model preferred embodiment; its structure is not limited to the above-mentioned shape of enumerating; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
