Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to windows of general buildings, houses, etc., or large stores,
The present invention relates to a multi-layer plate glass (laminated plate glass) in which an intermediate layer is interposed between two plate glasses used as interior and exterior walls of large buildings such as hotels and offices.

[Conventional problems]

Conventionally, this type of plate glass has been used in various places such as windows of general houses due to the properties such as transparency and strength of the material.Recently, not only colorless and transparent plate glass but also colored transparent plate glass is used. Of course, by sticking a colored film on the surface of the plate glass or forming a coating surface of an inorganic compound, etc., the color is often emphasized,
Further, a plate glass having a highly decorative property, which has a change in translucency, is used by appropriately forming a concavo-convex processed surface or a blast processed surface that has been subjected to an etching treatment.

However, as mentioned above, only the semi-transparent surface can be expressed as the uneven surface or the blasted surface, and since the surface of the plate glass is processed, it is difficult to wash it if it is contaminated by long-term use and the processed surface is However, there were problems such as being easily scratched and poor in durability.

[Purpose of device]

In view of the above, the present invention results from the above-mentioned problems by forming a cutting surface on one plate glass that constitutes a multilayer glass plate or a laminated plate glass in advance, and forming a mirror surface on the cutting surface, as a result of the above-mentioned problems. Is to eliminate.

[Constitution of device]

According to the structure of the present invention, in a multi-layer plate glass in which an intermediate layer is provided between two plate glasses that are facing each other, a cutting surface having a triangular wave-shaped cross section is formed on one surface of one plate glass on the intermediate layer side. The mirror surface is formed on the slope of the machined surface in a certain direction by metal deposition or the like.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an enlarged sectional view of an essential part for explaining a multi-layer glass sheet according to the present invention.

INDUSTRIAL APPLICABILITY The present invention can be used not only as a decorative wall of a large store, a decorative wall of a lobby of a hotel or an inn, an interior material or an exterior material also serving as a decoration for a large building, but also a window of a general building, a house, etc. Or, it can be used anywhere such as furniture,
A cutting surface 3 having a triangular wave-shaped cross section is formed on one surface of one plate glass 1a of the multilayer glass plate 1A on the side of the intermediate layer 2a, and a mirror surface 4 is formed on a slope 3b of the cutting surface 3 in a certain direction by metal deposition or the like.
The main point is that

The present invention, as shown in FIG. 1, includes two glass plates 1a.1b.
A space holding member made of rubber or the like filled with a desiccant or the like is provided around the periphery to provide the intermediate layer 2a with a parallel space as appropriate,
Multi-layered glass 1A with a thick wall that produces soundproofing and heat insulating effects
However, it may be formed as a laminated glass (not shown).

And, the present invention, the cross section to one surface on the side of the intermediate layer 2a of the one plate glass 1a constituting the multi-layer plate glass 1A, for example, a right-angled isosceles triangle having a top 3a, a slope 3b and a groove 3C in the cross section. Means for forming a triangular wave-shaped cutting surface 3 and performing vacuum deposition, sputtering, ion implantation, or chemical vapor deposition of a reflective metal such as aluminum on at least a slope 3b of the cutting surface 3 in a certain direction. To form the mirror surface 4. It is also beneficial to form the mirror surface 4 on a part of the outer surface of the one plate glass 1a which is parallel to the bottom surface of the triangular wave-shaped cutting surface 3.

Due to the presence of the cut surface 3, for example, in a window glass such as a general sight, sunlight rays from the outside reach the cut surface 3 of the plate glass 1b and partially form a mirror surface 4. Although the light is transmitted from the sloped surface 3b that has not been processed, the rest is due to the prism effect of the cut surface 3 (more effective on the mirror surface 4 on the plate glass 1a) and the mirror surface 4 of the sloped surface 3b of the cut surface 3. Since the light is scattered and reflected, it is possible to prevent the excessive transmission of sunlight while maintaining the brightness. Therefore, especially in the summer season, the increase of the heat quantity in the room is prevented, while in the winter season, the heat quantity in the room is prevented from being released, so that the room can be efficiently cooled and heated.

Further, when a person visually inspects the multi-layered plate glass 1A of the present invention, it can be seen through in a state substantially the same as a normal plate glass when viewed in a direction perpendicular to the slope 3b of the cutting surface 3. When viewed in a direction with a slight angle to the slope 3b, the prism effect such as refraction and reflection allows the image to be seen through as a complex image due to the kaleidoscope effect, and also has the effect of being obscured. It also has excellent exterior decoration effects.

The cutting surface 3 is not exposed on the surface of the multi-layer plate glass 1A or the laminated plate glass 1B of the present invention, and one plate glass 1a constituting the respective plate glass 1A.1B is provided with one surface 2b on the intermediate layer 2a side. By forming the machined surface 3 on one side that is in close contact with, there is no concern that dust, dirt, etc. will adhere to the groove portions 3c between the adjacent slopes 3b of the machined surface 3 when used over time. In addition, even if the impact of small items such as wind is applied to the top
There is no fear that 3a will be chipped and the acute-angled state will not be impaired, and it does not take time and effort after washing, and is extremely excellent in durability.

[Effect of device]

As described above, the present invention is not only excellent in functionality such as soundproofing effect, heat insulating effect, and strength due to the intermediate layer of the multi-layered plate glass or the resin layer of the laminated plate glass, but also has a triangular wave-shaped cross section. Since the mirror surface is formed, the prism effect of the cut surface and the reflection of the mirror surface further improve the functionality such as the heat insulating effect, and the translucency,
It has extremely high decorativeness with complicated changes in reflectivity, and its cut surface is not the surface of each plate glass, but one side that is in close contact with the one side of the intermediate layer side of one plate glass that constitutes each in advance. Since it is formed, it is a very significant idea with excellent durability.
