Description

High performance pairs glass system with thermal break spacer

The present invention relates to a multilayer glass provided with a thermal cross-linking spacer, more specifically, a plurality of glass laminated in a predetermined interval spaced state is configured to be firmly coupled by the thermal cross-blocking spacer, the air layer formed between the glass By configuring the thermal cross-linking spacers to communicate with each other, it can be used stably installed in the high temperature or extreme temperature difference in which the pressure difference is generated, and relates to a high-performance multilayer glass is installed a thermal cross-linking spacer that can prevent condensation due to the indoor and outdoor temperature difference.

In general, due to the high quality of residential living environment and the improvement of cultural life, the double-glazed glass, which is recently used in soundproofing and insulation facilities, is produced by order production. The demand is gradually increasing in response to the desire of consumers to seek a more comfortable atmosphere.

Such a structure and installation method of the laminated glass is also provided to the consumer in various forms. As the prior art, US Patent No. 4624091 and Japanese Patent Laid-Open No. 11-229723 can be cited, and FIGS. 1 and 2 show an example thereof. According to such a prior art, a through hole of a predetermined size is formed in a building wall, and a chassis frame 10 is installed at an inner edge portion of the through hole, and a multilayer glass ( The inner edge of 12) is fixed with adhesive 12e.

The multilayer glass 12 is configured to form a compressed air layer therein by stacking metallic spacers 12d between a plurality of glasses, and the innermost edge of the glass frame 10 is the chassis frame 10. By being fixedly bonded to the engaging portion (10a) of the () by the adhesive 12e, the multilayer glass 12 is installed in a predetermined position.

Between the four-sided end portion of the multilayer glass 12 and the protrusion 10b of the chassis frame 10, a filling member is considered in consideration of the change in the length of the multilayer glass 12 and the chassis frame 10 that is relaxed and contracted according to the change of weather. 16) is inserted, and the outer finishing member 18, such as silicon, is applied to the outside thereof, thereby preventing the introduction of rainwater and outside air.

However, when the multi-layer glass 12 is installed in a building located in a low pressure zone such as a high zone (Daegyeongryeong, mountainous terrain), the compressed air accommodated in the double-layer glass 12 forms an outside of the low pressure zone. Have the property to expand toward them.

The compressed air present between the outer glass 12a and the central glass 12b gradually pushes the outer glass 12a to the outside with a considerable force, and as time passes, the outer glass 12a with a small amount of adhesive The outer glass 12a is separated from the spacer 12d even with a small impact while being gradually separated from the bonded spacer 12d, thereby shortening its lifespan and requiring frequent repair work and reinstallation.

Recently, in order to prevent the outer glass 12a from being easily separated from the spacer 12d, multilayer glass 12 having a thicker thickness of the glass surface has been manufactured and installed. As the glass surface is made to be too thick, the size is enlarged, there is an inefficient problem to increase the production cost and secure an expanded installation space.

When the multilayer glass 12 is installed in a building, there is a problem in that water droplets are generated in the chassis frame 10 and the inner glass 12c when the difference between the outside temperature and the indoor temperature becomes large, such as in winter.

That is, the spacer 12d provided at the edge portion between the glass surfaces of the multilayer glass 12 is manufactured and installed with a metal material having high thermal conductivity such as aluminum, so that external cold air is blown out through the outer glass 12a. The conducted cold air is sequentially conducted to the inner glass 12c through the center glass 12b and the spacer 12d to generate water droplets as the warm and cold air crosses the room. The water droplets formed at the ends of the inner glass 12c not only shortened the life of the adhesive 12e adhered to the laminated glass 12 but also reduced the function of the member for fixing the laminated glass 12.

Frost and water droplets are also partially generated in the close contact portion of the inner glass 12c in contact with the outer surface of the chassis frame 10, so that the field of view of the outside of the chassis may be narrowed.

The present invention was devised in view of the above problems, and a plurality of glass laminated in a predetermined interval is configured to be firmly coupled by a heat cross spacer, but the air layers formed between the glass are the heat cross spacers The main purpose is to maintain the same pressure between each air layer by being configured to communicate with each other by being able to use stably in the highlands.

Another object of the present invention is to provide a multi-layered glass structure that can prevent the generation of water droplets due to the temperature difference between the outside and the outside due to the thermal bridge blocking effect of the thermal cross-blocking spacer.

At least one central glass 33 manufactured to a size smaller than the inner and outer glass 32 and 34 is positioned.

In addition, both side surfaces of the thermally intersecting spacers 40 are structurally bonded to both edge portions of the inner and outer glass 32 and 34 with an adhesive 36. At this time, the coupling groove 42 is formed along the inner surface of the thermal cross-blocking spacer 40 so that the four-sided ends of the central glass 33 can be inserted, and the central glass 33 is the coupling groove. When coupled to (42), the four ends of the central glass 33 is fitted into the receiving portion (60a) of the gasket 60 having a fine hole is inserted into the coupling groove 42, both ends of the gasket (60) It is bonded to the inner surface of the thermal cross-blocking spacer 40 to firmly fix the central glass 33.

Coupling groove 42 of the 40 and the fine space is generated. Accordingly, the air layers are interchanged through the micro-pores of the gasket 60 to maintain the air pressure on both sides divided by the central glass 33 in the same air pressure state, and thus, due to the air pressure difference between the external air pressure and the internal air pressure. By preventing the outer glass 34 from being easily separated from the heat cross spacer 40, the outer glass 34 may be firmly adhered to the heat cross spacer 40 so that durability may be further improved.

To be able to insert a desiccant 46a, such as silica gel.

Such a desiccant 46a absorbs moisture and moisture generated from a difference between an indoor temperature and an external temperature when it is introduced into the multilayer glass 30 and the thermal crossover spacer 40 within a short time. By maintaining a dry state at all times inside the triple glass 30, it is possible to improve the durability of the multilayer glass 30.

A plurality of vent holes 48 may be formed in the heat cross-over spacer 40 to communicate the two air layers with each other so that the air layers divided by the central glass 33 maintain the same air pressure within a short time. In other words, the ventilation hole 48 is configured to communicate with the first space portion 44 of the thermal cross-over spacer 40 to equalize the pressure of the divided air layer, thereby expanding the force of the air layer to expand to the outside. The lowered glass 34 is able to maintain a state in which the outer glass 34 is firmly bonded to the thermal cross-blocking spacer 40.

A plurality of vent holes 33a may be formed in the central glass 33. The vent hole 33a equalizes the pressures of both air layers divided by the central glass 33 like the vent hole 48 of the heat cross spacer spacer 40 to minimize the pressure difference with the external air pressure. The outer glass 34 is formed to maintain a state in which the outer glass 34 is firmly bonded to the thermal cross-blocking spacer 40.

In addition, a strip-shaped sealing film 50 made of a metal material may be adhesively attached to the ends of the inner and outer glass 32 and 34 and the outer surface of the thermal cross-blocking space 40. When the sealing film 50 is installed and fixed to the multilayer glass 30 to the chassis frame 20, to prevent the glass frame edges are pressed by the chassis frame 20 made of a metal material by the minute vibration and external force to prevent damage. To be adhesively installed.

In the sealing film 50, which is a metal material, even when the multilayer glass 30 is finely moved and pressed by the chassis frame 20, the sealing film 50 is formed of the inner and outer glass 32 and 34 and the thermal cross-blocking spacer 40. By firmly holding the bonded state, the impact applied to the edge of the triple glass 30 is alleviated, so that the multilayer glass 30 can be maintained without being damaged and that is caused by the deterioration of the durability of the sealing material.
