Description

  The present invention relates to a window glass structure capable of realizing heat insulation from outside light and outside air and prevention of condensation.

In recent years, the concept of energy saving has been widely spread, and the demand for improving the heat insulation of various buildings such as houses, offices, stores, etc. has been increasing year by year. It is clear that the heat insulation treatment in the window part together with the roof, the wall, the floor, etc. is indispensable for improving the heat insulation of the entire building, and there have been many attempts to improve the heat insulation of the window part.
It is clear that if a hollow multilayer glass plate is fitted into a window frame or if the entire glass window is doubled, the heat insulation will be dramatically improved, but these are costly and can be easily adopted. I could not do it. That is, the size of the hollow multi-layer glass plate is determined at the production factory, and it is practically impossible to cut freely according to the size of the window frame at the construction site, like the single-layer glass plate, The cost for construction was not cheap.

In addition, it has been almost impossible to change an existing glass window in which a normal glass plate is fitted to a hollow multilayer glass plate in terms of thickness and dimensions.
Even in the case of a new installation, it is very expensive to double the glass window itself, and although it has been done for a long time in cold regions such as Hokkaido, it can be said that it is a heat insulation measure that can be easily implemented. Absent.
Attempts were also made to attach a light-shielding film to the outside of the window glass, but although it was effective in reducing the indoor temperature in summer, the film itself deteriorated due to the influence of wind and rain. It has come to be conscious of that.

In order to keep the room temperature from the outside air or to prevent the dew condensation, try to attach a heat insulating material to the glass surface of the window. A suction cup mounting type heat insulating material configured to be attached detachably by attaching a suction member to the glass surface or a smooth wall surface of the window by attaching the retaining member to the heat insulating material. It has been proposed (see Patent Document 1).
In this case, due to the difference in coefficient of thermal expansion between the glass and the synthetic resin heat insulating material, there is a problem that the heat insulating material is distorted and the scenery outside the window through the heat insulating material is significantly distorted.

JP 2001-227254 A

  The present invention intends to solve the above-mentioned problems, and has a composite heat insulating window glass structure that does not cause distortion in the heat insulating material along the window glass even when the temperature of outside light / outside air changes. The issue is to provide.

  The composite heat-insulating glazing structure of the present invention is characterized in that a C-shaped holder is attached to the outer periphery of the effective surface of the window glass, and the C-shaped holder is used to hold the heat insulating material. It is preferable that at least one of the C-shaped holders attached to the four circumferences of the window glass can be opened and closed.

  The heat insulating material in the composite heat insulating window glass structure of the present invention absorbs the difference in thermal expansion amount from the window glass material within the swallowing capacity of the C-shaped holder, so that the heat insulating material can be seen through even if the temperature changes. There is no distortion.

The present invention is based on absorbing and dealing with the amount of thermal expansion by utilizing the possibility of sliding / moving the material to be held by the C-shaped holder.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a conceptual diagram showing a relationship between a C-type holder provided on a window glass in the composite heat-insulated window glass structure of the present invention and a heat insulating material held in a swallow of the C-type holder, and FIG. It is a conceptual diagram of an example which shows the relationship between a C-type holder and a heat insulating material in the first embodiment of the present invention. FIG. 3 is a conceptual diagram showing the structure of an improved C-type holder according to the second embodiment of the present invention.
FIG. 1 shows a heat insulating material 4 held by a C-shaped holder 3 attached to the outer periphery of an effective surface of a window glass 2 fitted in the window frame 1.

The C-shaped holder 3 is attached to the effective surface of the window glass 2 inside the window, that is, the outer periphery of the portion not covered with the window frame 1 by using, for example, a double-sided tape (not shown). Has been. If there is a gap between the window frame 1 and the C-shaped holder 3, the state of the outside air is reflected in the room through the gap. Therefore, the gap may be constructed to be zero as much as possible. desirable.
A heat insulating material 4 is inserted into the holding port 5 of the C-type holder 3. The heat insulating material 4 is slidable with respect to the C-shaped holder 3 and is inserted into the swallow 6 of the C-shaped holder 3 with an appropriate margin 7. That is, the margin 7 can absorb a change in length based on a difference in thermal expansion coefficient between the window glass 2 and the heat insulating material 4.

According to the first embodiment of the present invention, the C-shaped holder 3 disposed on the upper side of the window glass 2 and the left and right side holders may be used, but in the illustrated example, the right side C-shaped holder. The left side C-shaped holder (not shown, but the C-type holder disposed on the lower side) is relatively narrow.
According to such a structure, when the heat insulating material 4 is moved in the upper right direction, the heat insulating material corner portion at the lower left corner portion is released from the C-shaped holder, and the heat insulating material is used by utilizing the elasticity of the heat insulating material. It becomes possible to distort and to take out the heat insulating material from the C-shaped holder.
The heat insulating material can be similarly mounted on the C-shaped holder.
In this case, by using a sucker jig (not shown) or the like, a part of the heat insulating material is moved using the elasticity, and a part of the heat insulating material is deformed / distorted to be taken out or moved. The operation can be performed.
When handling the heat insulating material, for example, it is convenient to use a handle-like jig equipped with a suction cup, for example.

In the second embodiment of the present invention, as shown in FIG. 3, at least one of the C-shaped holders attached to the four circumferences of the effective surface of the window glass can be opened and closed. An upper piece (opening / closing piece) 8 of the openable / closable C-type holder that can be opened and closed is connected to a lower piece (fixed piece) 9 of the openable / closable C-type holder via a thin portion 10 so as to be opened and closed. The upper piece and the lower piece are formed with a suitable number of male and female pairs of hooks 11 and 12 such as hooks.
According to this aspect, with the upper piece (opening / closing piece) 8 of the open / close C-type holder opened, the side piece is slid from the side into the swallowing of the adjacent C-type holders from above the open / close C-type holder. Insert thermal insulation into In this case, there is no need for a handle-like jig equipped with a suction cup.

The C-shaped holder is fixed to the window glass by an appropriate means such as an adhesive or a double-sided adhesive tape. The sealing property is maintained between the C-type holder and the heat insulating material due to the elasticity of the C-type holder.
By these adhering modes, the space between the window glass and the heat insulating material is sealed within a practical range, and heat transfer between the room temperature and the outside air temperature is blocked, and at the same time, there is no possibility of causing condensation.
The C-shaped holder can be made of, for example, steel, stainless steel, or plastic.

  The heat insulating material can be made of, for example, polycarbonate, acrylic, or vinyl chloride. The heat insulating material can be a translucent material when importance is placed on daylighting, and a reflective material can be used when importance is placed on blocking heat entering the room through glass. .
