Description

Vacuum Multi-Layer Glass

The present invention relates to a multilayer glass for use in windows and doors, and more particularly, to a vacuum multilayer glass having a vacuum layer and an air layer.

As architectural technology has advanced, multilayer glass has been developed that is small in volume and excellent in appearance but also excellent in thermal insulation. The multilayer glass is provided with two or three or more sheets of glass, and is formed to block the temperature of the outside and the interior of the building using the multilayer glass by forming an air layer between the panes.

However, since the insulating layer includes an air layer, the thermal insulation performance is improved compared to the general plate glass, but the air layer is filled with an air medium, so that the convection phenomenon caused by the air medium may not be effectively blocked. Therefore, a vacuum multilayer glass has been developed that can effectively improve the thermal insulation performance degradation by conduction and convection.

The conventional vacuum multilayer glass is composed of three panes, and a vacuum layer is formed between the first and second panes, and an air layer is formed between the second and third panes. Therefore, heat transfer due to convection may be blocked through the vacuum layer, and heat transfer due to conduction may be canceled through the air layer, thereby ensuring optimal heat insulating performance. The vacuum layer separates the first and second panes by a predetermined distance, removes air between the first and second panes by using a vacuum pump, and after the air removal of the first and second panes is completed, It is produced by sealing the ends of the two panes with a sealing so that the vacuum of the vacuum layer can be maintained.

In addition, the air layer may be manufactured by seating a rod, which may be referred to as a spacer or spacer, to provide a space between the second and third panes, and filling the between the second and third panes with dry air. Can be.

However, the vacuum multilayer glass including the vacuum layer and the air layer has the following problems. If the temperature difference between the outside and the inside of the building in which the vacuum multilayer glass is installed is increased, the plate glass constituting the outer and inner sides of the vacuum multilayer glass is shrunk or expanded, respectively, and the vacuum multilayer glass may be broken. In particular, when the vacuum sealing that maintains the vacuum state of the vacuum layer is damaged due to the shrinkage and expansion, the vacuum degree of the vacuum layer continues to drop, and thus the original function of the vacuum multilayer glass may be lost.

Accordingly, although research and development have been conducted in the direction of improving the vacuum sealing for sealing between the panes forming the vacuum layer, this causes a problem of increasing the production cost of the vacuum multilayer glass. Therefore, there is a need to find a way to fundamentally improve the structure of the vacuum laminated glass to maintain the function of the vacuum laminated glass for a long time.

In order to solve the above problems, an object of the present invention is to provide a vacuum multilayer glass having a structure capable of stably maintaining the vacuum state of the vacuum layer even when the temperature difference between the outside of the building and the inside becomes severe.

The vacuum multilayer glass according to an embodiment of the present invention is a vacuum multilayer glass composed of at least first to third panes so that a vacuum layer and an air layer may be provided together, and the vacuum layer is formed between the first and second panes. And the air layer is formed between the second and third panes, the second pane has the shortest length, and a vacuum sealing to seal between the first and second panes forming the vacuum layer, the air layer. A gap between the first and third panes and a gap between the second and third panes to form a gap between the vacuum rods, the rods and the ends of the second pane, the first and third panes being in contact with each other. It includes a multilayer glass sealing provided to seal between the three panes, to protect the vacuum layer and the air layer.

In addition, the vacuum laminated glass according to another embodiment of the present invention is a vacuum laminated glass composed of at least first to third panes so that the vacuum layer and the air layer can be parallel, the vacuum layer between the first and second panes Is formed, wherein the air layer is formed between the second and third panes, the second pane has the shortest length, and a vacuum seal for sealing between the first and second panes forming the vacuum layer, Located between the first and the third plate glass, between the first and the third plate glass and between the first and the third plate glass and the first bar and between the first and the third plate glass, and between the first and the third plate glass It includes a multilayer glass sealing provided to seal the gap between the vacuum layer and the air layer.

According to the present invention, by varying the length of the plate glass constituting the vacuum double-layer glass to be provided with a double-layered glass sealing to protect the vacuum sealing and liver rods, by maintaining the vacuum layer and the air layer stably excellent heat insulation, pressure temperature It is effective to keep the function of the vacuum laminated glass which is robust to change for a long time.
