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 bonded by a synthetic resin 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. 1 and 2 illustrate an example, a through hole having a predetermined size is formed in a building wall, and a chassis frame 10 is installed at an inner edge of the through hole, and a coupling portion of the chassis frame 10 is illustrated. The inner edge of the multilayer glass 12 is fixed to the 10a with an 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 has been invented in view of the above problems, and a plurality of glass laminated in a predetermined interval is configured to be firmly bonded by a synthetic resin spacer, but the air layers formed between the glass to the synthetic resin spacer The main purpose is to maintain the same pressure between each air layer by being configured to communicate with each other by the same, so that it can be used 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 synthetic resin spacer.

The outer surface of the chassis frame 20 is formed with a protrusion 21 protruding vertically, the coupling portion 22 is formed on the adjacent surface of the protrusion 21, the laminated glass according to the present invention 30 is installed.

The multilayer glass 30 includes inner and outer glass 32 and 34 having the same size, and the edges of the inner and outer glass 32 and 34 face each other between the inner and outer glass 32 and 34. 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 synthetic resin spacer 40 are structurally bonded to both edge portions of the inner and outer glass 32 and 34 with an adhesive 36. In this case, the coupling groove 42 is formed along the inner surface of the synthetic resin spacer 40 so that the four ends of the central glass 33 can be inserted, and the central glass 33 is the coupling groove ( 42, the four ends of the central glass 33 is fitted into the receiving portion 60a of the gasket 60 having micropores and inserted into the coupling recess 42, and both ends of the gasket 60 are made of synthetic resin. It is adhered to the inner surface of the spacer 40 to firmly fix the central glass 33.

As the central glass 33 installed in the coupling groove 42 is sufficiently in close contact with the coupling groove 42 of the synthetic resin spacer 40 installed at its lower portion by its own weight, the synthetic glass spacer 40 is disposed on the upper portion of the central glass 33. Coupling groove 42 of the) and the minute space will be 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. Since the outer glass 34 is prevented from being easily separated from the synthetic resin spacer 40, the outer glass 34 may be firmly adhered to the synthetic resin spacer 40 to further improve durability.

In the present invention having such a configuration, the inner and outer glass (32,34) is fixedly bonded by a synthetic resin spacer 40 is attached along its rim, the central glass 33 located in the center of the gasket 60 By being fixedly coupled to the synthetic resin spacer 40 in a state where it is placed, external cold air is not conducted to the room even when the external temperature is low, and thus water droplets are not generated on the inner glass surface.

Since the triple glass 30 is always maintained in a dry state, it is possible to improve the durability of the multilayer glass 30.

A plurality of vent holes 48 may be formed in the synthetic resin spacer 40 to communicate the two air layers with each other so that both air layers divided by the central glass 33 maintain the same air pressure within a short time. In other words, the vent hole 48 is configured to be in communication with the first space portion 44 of the synthetic resin spacer 40 to equalize the pressure of the divided air layer, so that the expansion force of the air layer to expand to the outside is Lowered the outer glass 34 will be able to maintain a state that is firmly bonded to the synthetic resin spacer 40.

A plurality of vent holes 33a may be formed in the central glass 33. The vent hole 33a equalizes the pressure in both air layers divided by the central glass 33 like the vent hole 48 of the synthetic resin spacer 40 described above, thereby minimizing the pressure difference with the external air pressure. The outer glass 34 is formed to maintain the state firmly bonded to the synthetic resin spacer 40.
