Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating device used in houses located in cold regions such as Hokkaido.

In such houses for cold regions, a high degree of heat insulation is required, and for this reason, a heat insulating material is provided not only in the outer walls but also in the inner walls to provide double insulation. In this case, the insulation material on the inner wall side is
Although it is attached within a frame for an inner wall that is attached to a frame, if there is a gap between the frames, there is a drawback that sufficient heat insulation cannot be obtained in this part. Particularly in buildings where a steel frame with good heat conductivity is used for the frame, the frame is attached to the frame, so the frame is directly exposed in the gap between the frames.
Therefore, the heat inside the room is directly transmitted to the outside through this frame.

On the other hand, houses naturally require electrical wiring and gas piping, but these wiring and piping must not be exposed indoors and must be housed in a manner that is easy to install.

The present invention has been made in view of the above points, and has a structure in which a heat insulating material is also inserted into the gap between the frames, and furthermore, wiring or wiring is inserted into the space on the back side of this heat insulating material. Make sure to install piping, and
The present invention is characterized in that a wiring box is attached by cutting out a portion of the heat insulating material, and the heat insulating material is adhered to the back surface of the wiring box.

The configuration of the present invention will be explained below based on the drawings showing one embodiment.

In FIGS. 1 and 2, 1 is the steel frame of the building, 2 and 2 are a foamed synthetic resin heat insulating material 3, and surface plates 4a and 4b attached to both the front and back surfaces of the heat insulating material 3. The outer wall panels 5, 5 are the inner wall frames 6,
6 vertical frames are shown. 7, 7 is the vertical frame 5,
This step is formed by cutting out the front half of the outer surface of No. 5.

In the above, the outer wall panels 2, 2 have their ends in contact with the outer surfaces of the frames 1, 1, and the inner wall frames 6, 6 have their vertical frames 5, 5 inside the frames 1, 1. The supporting metal fittings 8a, 8b are brought into contact with the side surfaces of the outer wall panels 2, 2, the ends of the back side surface plates 4b of these outer wall panels 2, 2, and the step portions 7, 7 of the vertical frame 5, and these supporting metal fittings 8a, 8b are
and the tightening bolt 9 inserted into the gap between the frame assembly 1 and 1.
At this step, both the outer wall panels 2, 2 and the inner wall frames 6, 6 are fixed. 10, 10 are inner wall frames 6, 6
It is an insulating material made of foamed synthetic resin installed inside the
The heat insulating materials 10, 10 are attached to the inner wall frames 6, 6 in advance.

A gap 11 is created between the vertical frames 5, 5 of the inner wall frames 6, 6 attached as described above, but in this embodiment, the step portions 7, 7
A heat insulating material 12 also made of foamed synthetic resin is inserted into this gap 11 formed on the outer side, and furthermore, in the present invention, a space 13 is formed on the back side of this heat insulating material 12. However, this space 13 is provided with electrical wiring 14 or wiring or piping such as a gas pipe. In this embodiment, this space 13 is formed by providing a groove 15 on the back surface of the heat insulating material 12.
does not necessarily have to be provided. 16 shown in Figure 1
is an inner wall finishing plate attached to the front surface side of the inner wall frames 6, 6.

Next, reference numeral 17 shown in FIG. 2 is a wiring box connected to the above-mentioned wiring 14, and this wiring box 17 is connected to the heat insulating material 12 inserted into the above-mentioned gap 11.
A part of the wiring box 17 is cut out and installed in the gap 11 so that its surface part is exposed to the interior of the room.A similar heat insulating material 18 is placed on the back side of the wiring box 17 in advance as shown in FIG. As shown in FIG. 3, 18 layers of heat insulating material are also formed on the back surface of the wiring box 17.

The present invention has the above-mentioned configuration, and as described above, in the present invention, since the heat insulating material is also provided in the gap created between the inner wall frames, the heat insulation properties are good.
Furthermore, the present invention utilizes the space on the back side of the heat insulating material to provide wiring or piping, and these piping and piping can be completely housed, resulting in a good appearance. In addition, since the wiring etc. are installed in the gap between the inner wall frames, even after the frames are installed, there is no need to break the heat insulating material provided inside the inner wall frames. In addition, even if the mounting position of the wiring box or the like is different, it is only necessary to cut the heat insulating material in the gap, and since the heat insulating material is generally easy to cut, on-site construction is easy. Furthermore,
In the present invention, since the insulation material is also provided on the back side of the wiring box, the insulation properties are better, and this insulation material can be attached to the wiring box in advance as in this embodiment, making it easier to install. This has the effect of making it easier.
