Description

[Detailed description of the invention] The size of the heating and cooling load of houses and buildings can be significantly reduced by improving the insulation properties of the constituent materials such as outer walls, ceilings, and floors.

For example, the heat transmission coefficient of a wooden panel used for an exterior wall is 19.
kcal/m 2hk, but 15cm on this surface
Adding a layer of glass fiber reduces that value to about 1.

Therefore, if a similar insulation layer is installed on the ceiling, floor, etc.
It can be seen that if the loss due to ventilation is excluded, the energy required for air conditioning and heating can be reduced to the usual h, resulting in significant energy savings.

Generally, the exterior walls have transparent or semi-transparent parts such as windows to let in sunlight.

The glass used in such areas has a fairly high thermal conductivity and is thin, so it has a large heat transmission coefficient, and even if the window area is small in proportion to the wall surface, it will have a large effect on reducing the insulation of the entire room. .

For this reason, in recent years, the usefulness of double-glazed windows in which a gas layer such as nitrogen gas is provided between two glass plates has been recognized.

However, the degree of improvement in heat insulation properties resulting from this is extremely small compared to other walls having a 10 to 15 cm layer of heat insulating material.

For example, a sheet of glass with a thickness of 3 mm has a heat transmission coefficient of 5.5.
kcal/m2hk, but even with a double glass structure made of two similar glasses, the value is 2.6 kcal/m
It will only be 2hk.

In this way, with regard to energy-saving technology for residential heating and cooling, the structures and materials of ordinary exterior walls, ceilings, floors, etc. can be solved relatively easily, but there are still major problems remaining regarding transparent wall surfaces and window materials. There is.

The present invention eliminates the above-mentioned conventional drawbacks.

As a structure for this purpose, the present invention seals both ends of a hollow glass tube whose cross section is composed of a continuous curve with an ellipse or a substantially circular shape, and connects a plurality of glass tubes that are evacuated inside with a soft sealing material interposed between them. The glass tubes are arranged in one plane, and the array of glass tubes is sandwiched between transparent plates.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a cross section of a heat insulating transparent wall device according to an embodiment of the present invention.

FIG. 4 is a perspective view of the finished structure seen from inside the room.

That is, the frame 2 is provided so as to fit into the opening of the wall surface 1 .

A glass plate 3 is attached and fixed to the frame from the outside and inside using mounting fittings 4 and screws 5.

A sealant material 6 is injected between the mounting bracket 4 and the glass plate 3, so that the space between the two glass plates 3 is sealed.

As shown in FIG. 2, the hollow glass tube 7, which has an elliptical cross section, is sealed at both ends, and the inside is evacuated to a pressure of 10-3'tOrr or less through the opening 8, and the tube is sealed.

The soft sealing material 9 shown in FIG. 3 is a silicone rubber material with a rectangular cross section.

As shown in FIG. 1, the hollow glass tube 7 and the sealing material 5 are sandwiched between the glass plates 3 and cover the entire opening of the frame 2.

The short diameter of the hollow glass tube 7 is made slightly shorter than the distance between the glass plates 3, and the hollow glass tube 7 lightly touches any of the glass plates 3 to maintain its arrangement.

Reference numeral 10 denotes an opaque white plastic plate, and in the window structure shown in FIG. 4, the edges of the hollow glass tube 7, the scratches 8, etc. are removed to maintain the aesthetic appearance.

According to the present invention, the area to be evacuated is shaped like a hollow glass tube whose cross section is an elliptical or approximately circular continuous curve;
．． It has sufficient pressure resistance even with a thickness of about 5 mm, so it is structurally simple and lightweight enough to be easily applied to doors, etc., and can be manufactured at low cost.The thermal transmission coefficient changes depending on the ratio of the major axis to minor axis of the ellipse. This is similar to the spring of a double-glazed structure, and it has a great practical effect as it can be used at the same time as or better than other wall surfaces with insulation.
