Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a heat insulating glass window.

[0002]

2. Description of the Related Art One of the strong demands for modern buildings is heat insulation, and therefore, the glass windows are also required to have a heat insulation structure. Conventionally, the glass window has a double glass structure to achieve heat insulation.

[0003]

However, there is a problem that a glass window having a double glass structure is expensive. This is because the window frame for the glass window is complicated in shape and considerably expensive compared to the window frame for the ordinary glass window, and the amount of expensive glass plate used is doubled. .

[0004] The inventor of the present application has recognized the necessity of obtaining heat insulation by adding a resin plate to an ordinary glass window, and has made an attempt to meet the necessity. The first attempt of the present inventor is, for example, that the inner surface of the glass sheet whose periphery is fitted to the window frame is transparent (may be translucent or non-transparent).
A simple resin plate is bonded through a spacer.

[0005] However, such attempts have had significant problems. This is because there is a large difference in the coefficient of thermal expansion between the sheet glass and the resin sheet.The resin has a larger coefficient of thermal expansion than the sheet glass. The problem was that it was short.

Accordingly, the present inventor has sought to find a means for preventing the occurrence of thermal stress due to a temperature change due to a difference in thermal expansion coefficient between a double structure using a glass plate and a resin plate. Reached.

That is, the present invention has a low price and heat insulating properties,
An object of the present invention is to provide a heat-insulating glass window which is not subjected to thermal stress due to a temperature change and therefore has a long life.

[0008]

According to a first aspect of the present invention, there is provided a heat insulating glass window in which a plate mounting portion containing a magnet is magnetically attracted to a portion slightly inside a frame of one main surface of a plate glass via a steel paper. A resin plate is attached to the plate mounting portion.

Therefore, according to the heat insulating glass window of the first aspect, since the glass plate and the resin plate form a double plate structure, heat insulation can be obtained. Since the resin plate does not need to be fitted into the window frame, there is no need to use a window frame for a double glass structure. Moreover, the price of resin is lower than that of sheet glass. Therefore, the heat insulating glass window can be provided at a lower price than before.

The positional relationship between the plate glass and the resin plate is maintained via magnetic force, and the magnetic force allows displacement in the plate surface direction due to a temperature change due to a difference in thermal expansion coefficient therebetween. Therefore, there is no possibility that thermal stress occurs in the glass sheet or the resin sheet due to the temperature change.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

FIG. 1 is a sectional view showing a first embodiment of the heat insulating glass window of the present invention. 1 is a sash frame, 2 is a fitting hole into which a peripheral portion of a plate glass (4) to be described later fits (note that the shape is not necessarily a hole but may be a concave or groove shape), and 3 is the fitting. Rubber packing fitted into the hole 2;
Reference numeral 4 denotes a fitting hole 2 of the sash frame 1 through the rubber packing 3.
Is a sheet glass fitted with a peripheral portion. Then, a resin plate (9) to be described later is stacked on the plate glass 4 at intervals. The point is described below.

Reference numeral 5 denotes an adhesive for attaching the steel paper 6 to a portion of the plate glass 4 inside the sash frame 1. 7
Is a plate mounting member magnetically attached to the steel paper 6, is made of resin containing a magnet, and has a fitting groove 8 into which an edge portion of the resin plate (9) fits. Reference numeral 9 denotes a resin plate whose edge is fitted into the fitting groove 8. The resin plate 9 may be transparent or translucent, or may be non-transparent.

Numeral 10 denotes a spacer made of resin containing a magnet, and a space between the plate glass 4 and the resin plate 9 is kept at a predetermined size at a portion inside the edge of the resin plate 9. 5,5
Is an adhesive and 6 is a steel paper.

The plate mounting member 7 is attached to the plate glass 4 by a magnetic force acting between itself and the steel paper 6 adhered to the plate glass 4 and holds the resin plate 9 while maintaining the resin plate 9 in contact with the plate glass 4 due to a temperature change. Displacement in the direction of the plate surface with respect to the resin plate 9 is allowed.

Similarly, the spacer 10 maintains its position stably between the plate glass 4 and the resin plate 9 by a magnetic force acting between itself 10 and the steel paper 5 bonded to the plate glass 4, and serves as a spacer. While allowing the displacement between the plate glass 4 and the resin plate 9 in the plate surface direction due to the temperature change. The spacer 10 is not indispensable.

According to such a heat insulating glass window, since the glass sheet 4 and the resin plate 9 form a double transparent plate structure, heat insulation can be obtained. And the resin plate 9 is the sash frame 1
There is no need to use a window frame for a double-glazed structure because it does not need to be fitted into the frame. Further, the resin plate 9 is lower in price than the plate glass. Therefore, the heat insulating glass window can be provided at a lower price than before.

The positional relationship between the glass plate 4 and the resin plate 9 is maintained via a magnetic force, and the magnetic force allows displacement in the plate surface direction due to a temperature change due to a difference in thermal expansion coefficient therebetween. .
