[0002]

[Technical Background of the Invention] The wall structure of a wooden building, such as a wall or a ceiling, is composed of structural materials such as columns and rafters arranged in parallel, and exterior and interior plate materials sandwiching these. May be For example, as shown in FIG. 11, a wall structure constituting a wall of a building includes a pillar 5 that is provided in parallel between a base 1 and a beam 4, and an exterior plate 6 and a pillar 5 that sandwich the pillar 5. An interior plate 7 is provided. In such a wall structure, in recent years, a heat insulating material 8 made of a hard foamed resin may be laid between the exterior plate material 6 and the interior plate material 7 from the viewpoint of improving indoor heat insulation and airtightness. . In the case of the inner heat insulation method, the heat insulating material 8 is constructed by arranging the outer plate 6 and then arranging it without any gap between the pillars 5 so that a space s is formed on the outer plate 6 side, and then for the interior. It is common to build a board 7.

However, in such a conventional wall structure,
Since it is difficult to mount and fix the heat insulating material 8 itself such that a space s is formed on the exterior plate 6 side, it is necessary to use a metal fitting having a special structure or an auxiliary tool such as a joiner. Therefore, the number of parts increases, and not only the construction on site becomes troublesome, but also the heat insulating material 8 and the interior plate 7.
There was a risk that a large gap would be formed. If the gap between the heat insulating material 8 and the interior plate 7 is large, outside air may enter and affect the indoor temperature. As a result, a large amount of dew is generated on the surface of the heat insulating material 8 on the side of the interior plate 7, and the heat insulating material 8 contains water, so that the heat insulating property of the wall structure is significantly reduced.

Insufficiency of the heat insulation function such as a gap does not occur.

In the above, a preferred embodiment of the present invention has been described. In the present invention, the heat insulating panel has a thickness smaller than the distance between the exterior plate material and the interior plate material, and the interior panel material or the exterior Having a main body disposed so that one surface thereof is in contact with the board material, and a side edge portion which is thicker in the direction of the exterior board material or the interior board material and has a thickness substantially equal to the distance between the two board materials. If so, the direction in which the heat insulating panels are arranged is not particularly limited. Therefore, for example, in the heat insulating wall structure of the present invention, the heat insulating panels may be arranged so that the side edges are located above and below the main body, and such an embodiment will be described with reference to FIGS. .

FIG. 5 is a longitudinal sectional view of a wall structure according to another embodiment of the present invention, FIGS. 6 and 7 are perspective views of a heat insulating panel applied to the wall structure, and FIG.

A slit 40 is formed in a side edge portion 39 at a right angle to the slit 40, the slit 40 being cut from one surface side and not reaching the other surface.

That is, in a wooden building, through pillars, pipe pillars, studs, and the like determine the dimensions of the building based on the center positions thereof. However, since the dimensions of one side of these pillars are different, the centers of these pillars are different. The distance between the positions is fixed, for example, between 1/4 and 455
mm, the distance between the columns, that is, the interval between the end faces of the columns,
It will be different.

More specifically, as shown in FIGS. 8 and 9, when the distance between the center positions of the studs 21 and the studs 21 and between the studs 21 and the tube post 41 is 455 mm, the studs 21 of 45 × 105 are used.
While the distance between the end faces is 410 mm, 45 × 1
The distance between the end faces of the studs 21 and the 105 × 105 tube 3 is 380 mm, and there is a dimensional difference of 30 mm between the end faces of these pillars.

Therefore, in the heat insulation panel 38 of this embodiment,
The slit 40 is formed at a position where the clearance and the dimensional difference of 30 mm are expected, that is, at a position where the width of the side edge portion 39 is 30 mm. Thermal insulation panel 3 having such a configuration
