[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel for a building. For example, even if the distance between end faces of pillars, studs, etc. of a wooden building is various, it expands and contracts, so that airtightness is provided between them. Also, the present invention relates to a heat insulating panel that can be laid without heat insulation loss.

[0002]

[Technical background of the invention] In wooden buildings, through columns, pipe columns,
The studs determine the size of the building based on the center position, but the dimensions of one side of these pillars are different. for that reason,
The interval between the center positions of these pillars is, for example, 1/4,
Although it is constant at 455 mm, the intervals between the end faces of these columns are various.

In detail, for example, as shown in FIG.
The distance between the center positions of the through pillar 1 and the stud 2 is 455 mm. One side of the through pillar 1 is, for example, 120 mm, and one side of the stud is 30 to 45 mm. Therefore, the distance a between the end faces of the through pillar 1 and the stud 2 is 38 at the maximum.
0.0mm, which is a minimum of 372.5 mm.

Further, assuming that the column denoted by reference numeral 1 is a tube column, one side of the tube column 1 is, for example, 105 mm. Therefore, the distance a between the end faces of the tube post 1 and the stud 2 is 387.5 mm at the maximum and 370 mm at the minimum.

Accordingly, the distance a between the through column or tube column 1 and the stud 2 is 387.5 mm at the maximum and 37 mm at the minimum.
0 mm and the difference is 17.5 mm, which is various.

The distance between the center positions of the stud 2 and the stud 3 is also 455 mm.
Since it is 45 mm, the distance b between the end faces of the studs 2 and 3 is a maximum of 425 mm and a minimum of 410 mm, and the difference is 15 mm, which is various.

Further, a comparison between the distance a between the end faces of the pillars 1 and the studs 2 and the distance b between the end faces of the studs 2 and 3 is 425 mm at the maximum and 370 mm at the minimum. The difference is 55 mm, which is various.

[0008] From the above, through column 1, tube column 1, studs 2, 3
The distances a and b between the end faces are various because the dimensions of these sides are different. By the way, in a wooden building, from the viewpoint of improving indoor heat insulation and airtightness, a heat insulating material made of a hard foamed resin may be laid between the through pillar 1, the tubular pillar 1, and the studs 2, 3. . However, as described above, since the distances a and b between the end surfaces of these pillars are various, for example, as shown in FIG.
When the same heat insulating material 4 is laid between the stud 2 and the stud 2 and between the stud 2 and the stud 3, a gap is formed between the stud 2 and the stud 3 on the stud 3 side as shown in FIG. Therefore, in order to fill this gap, a heat insulating piece 5 cut in the field work is laid in this gap (adding width).

[0009] However, since the cut heat insulating piece 5 is worked on site, there is a problem that a gap is easily formed between the heat insulating piece 5 and the stud 3. Further, even if the heat insulating piece 5 is laid airtight by on-site work, the wood of the stud 3 is dried and deformed. As a result, a gap is formed between the stud 3 and the heat insulating piece 5, and the airtightness and heat insulating property are obtained. A problem arises in that is deteriorated. Further, when an earthquake or the like occurs, there is a possibility that the heat insulating material 4 and the cut heat insulating pieces 5 may fall off.

On the other hand, it is also conceivable to prepare a heat insulating material having a width larger than the width between the pillars in advance, and to cut (width cut) the wide heat insulating material in accordance with the interval between the end faces of the pillars by field work. . However, there is a problem in that this cutting work must be performed at many places, and the work is very complicated.

Further, it is conceivable to use heat insulating materials of various sizes corresponding to the intervals between the end faces of the pillars. However, in such a case, there is a problem that the manufacturing cost of the heat insulating material increases.

As described above, conventionally, due to the various intervals between the end faces of the pillars, various sizes of heat insulating materials are prepared, or the heat insulating materials are laid by performing width cutting and width addition. There is a problem that the airtightness and the heat insulation are deteriorated.

[0013]

This invention has been made in view of the above-mentioned circumstances, and even if the distance between the end faces of the structural members of the building is various, the space between the end faces can be obtained by expanding and contracting. An object of the present invention is to provide a heat insulating panel which can be laid in an airtight manner and without heat loss.

[0014]

SUMMARY OF THE INVENTION In order to achieve this object, a heat insulating panel according to claim 1 of the present invention is a heat insulating panel laid between structural members of a building, and comprises two or more halves. halves mutually in position of opposing, two or more halves to allow shifting in the direction or away from the direction approaching each other, the thickness of the concave and convex engaging part which shiftably fitted to each other of
A plurality of heat insulating materials, which can be expanded and contracted,
At least one film or seal attached to at least one side of two or more halves of the heat insulating material so as to leave a portion that becomes a reservoir when the heat insulating material contracts.

In the present invention thus configured, in the thickness direction
Since the two halves constituting the heat insulating material can be shifted to each other by the plurality of concave / convex fitting portions formed in the heat insulating panel, the heat insulating panel can be expanded and contracted. At this time, a film is adhered to the heat insulating material so that a portion that becomes a reservoir when the heat insulating material contracts is left. This film, as described below,
In addition to serving as a moisture-proof sheet, it is attached to a pillar or the like of a structural member by staples or the like, and serves to fix the heat insulating panel between the pillars or the like.

As described above, in the present invention, since the heat insulating panel is extendable and contractible, even if the end faces of the structural members of the building, for example, the through pillars, the pipe pillars, and the studs are various, the heat insulating panel can be used. By expanding and contracting, the heat insulating panel can be laid in an airtight manner and without heat insulation loss by aligning the end face of the heat insulating panel with the end face of the structural member without any gap.

Therefore, unlike the related art, there is no need to prepare heat insulating materials of various sizes, and there is no need to perform width addition or width cutting by on-site work, resulting in deterioration of airtightness and heat insulation. Eliminate problems. Furthermore, since a film or sheet is stuck to the heat insulating material, and the film or sheet is attached to a structural member such as a column with staples or the like to fix the heat insulating panel, the heat insulating panel can be airtightly mounted. Further, when the unevenness in the unevenness fitting portion is finely divided, convection does not occur in the air stored in the unevenness, and the layer of this air can exert a heat insulating effect, leading to a decrease in heat insulating property. There is no.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Insulation panels according to two embodiments of the present invention will be described below with reference to the drawings. 1 to 4
It is Ru engages the first embodiment of the present invention.

First, a first embodiment will be described with reference to FIGS. FIG. 1 is an exploded perspective view of a heat insulating panel according to a first embodiment of the present invention. FIG. 2 is a horizontal sectional view of a wall of a wooden building when the heat insulating panel according to the embodiment is used as a wall panel and laid between pillars and studs. FIG.
Uses the heat insulation panel according to the same example as a wall panel,
It is a horizontal sectional view of the wall of a wooden building when this is laid between studs. FIG. 4 is a horizontal sectional view of a wall of a wooden building when the heat insulating panel according to the embodiment is used as a wall panel.

As shown in FIG. 1, a heat insulating panel 10 according to the present embodiment includes a heat insulating material 11 composed of two halves 11a and 11b, and a film 2 attached to both sides of the heat insulating material 11.
1 and 22.

The two halves 11a and 11 of the heat insulating material 11
A plurality of concave / convex fitting portions 12 and 13 are formed in the mutually opposing portions in the thickness direction, respectively. Each of the concave and convex fitting portions 12 and 13 has a plurality of convex portions 12 extending to a predetermined length.
a, 13a, and a plurality of concave portions 12b, 13b formed between the convex portions 12a, 13a and extending a predetermined length. The convex portions 12a, 13a, the concave portions 12b,
13b are fitted so as to be mutually shiftable. These convex portions 12a, 13a and concave portions 12b, 13b may be tightly fitted or may be loosely fitted. Therefore, with such a configuration, these convex portions 12a,
13a and the recesses 12b and 13b are shifted from each other,
The halves 11a and 11b can be shifted toward or away from each other, and the heat insulating material 11 can be expanded and contracted.

The number of the convex portions 12a and 13a and the concave portion 12
The number of b and 13b varies depending on the thickness and strength of the heat insulating material 11. For example, in the case of a heat insulating material having a thickness of 50 mm, a total of 10 to 5 uneven portions with a spacing of 5 to 10 mm can be provided. Although not limited to these and those shown, the greater the number, the more preferred. Because, as shown in FIG. 3, when the heat insulating material 11 is stretched,
Air is contained in the concave portions 12b and 13b, and this air can form a layer and exhibit a heat insulating effect. However, when the number of the protrusions 12a, 13a and the number of the recesses 12b, 13b are small, each dimension of the recesses 12b, 13b becomes large, so that convection of air occurs in the recesses 12b, 13b, and a stationary air layer is formed. However, there is a possibility that the heat insulation performance is reduced. On the other hand, when the number of the convex portions 12a, 13a and the concave portions 12b, 13b is large, the concave portions 12b, 13b
As a result, the recesses 12b, 13b
This is because the convection of air is blocked inside, a stationary air layer is formed, and the heat insulation performance is improved.

Further, the convex portions 12a, 13a and the concave portions 12
The shapes of b and 13b are not limited to those illustrated. For example, the tips of the protrusions 12a and 13a may be formed with roundness, and the bottoms of the recesses 12b and 13b may be formed with roundness.

Furthermore, the halves 11a, 1
1b is expanded polystyrene, expanded polyurethane,
It is formed from a foamed resin such as foamed polypropylene.
The foamed resin is not limited to these, and may be various types. Half body 11a, 1 having concave and convex fitting portions 11, 12
When molding 1b, it may be formed by integral molding such as in-mold molding, or the concave / convex fitting portions 11 and 12 may be formed by a post-process using a hot wire cutter, sawtooth, or the like.

Next, the film 21 adhered to one side of the heat insulating material 11 is located inside the room when the heat insulating panel 10 is laid, and functions as a moisture-proof film. Therefore, the film 21 may be a relatively thick sheet instead of the film. This film 21 is, for example, a polyethylene film having a thickness of about 0.1 mm,
It is not limited to these. Further, the heat insulating material 11
The film 22 attached to the other side is located outside the room when the heat insulating panel 10 is laid, and plays a role of a windproof film. However, when the windproof film is unnecessary, the film 22 is It does not have to be used. The windproof film 22 is generally formed of a material having both windproof performance and moisture permeability, such as Tyvek (trade name) and Gore-Tex (trade name). However, the present invention is not limited to these, and various types such as those in which fine holes are formed in an aluminum-deposited film and those in which a microporous film is adhered to a polyethylene nonwoven fabric may be used. Also,
The film 22 may be a relatively thick sheet instead of the film.

These films 21 and 22 are used as heat insulating materials 11
When sticking to the heat insulating material 11 as shown in FIG.
The films 21 and 22 are attached to the heat insulating material 11 so that the portions 21a and 22a serving as reservoirs are left at the time of contraction. This is because if the storage portions 21a and 22a are not provided, the heat insulating material 11 cannot be extended as shown in FIG. Therefore, this reservoir portion 21a,
When the heat insulating material 11 is extended, 22a becomes a general surface of the films 21 and 22, as shown in FIG.

When the heat-insulating panel 10 is used, for example, as a wall heat-insulating panel, the dimensions of the heat-insulating panel 10 are 455 mm between 1/4 width and 910-1 height.
820 mm. However, it is a matter of course that the present invention is not limited to these.

The heat insulating panel 10 thus configured
Is laid as a heat insulating panel for a wall, for example, as shown in FIGS. As shown in FIG. 2, through columns (or tube columns)
When laying the heat insulating panel 10 between the pillar 1 and the stud 2, the distance a between the end faces of the pillars 1 and 2 is relatively narrow (for example, 372.5 mm), so that the heat insulating panel 10 shrinks. It is laid between these pillars 1 and 2 in the state where it is made to be. The heat insulating panel 10 is attached to the columns 1 and 2 by fixing the ends of the films 21 and 22 to the columns 1 and 2 with staples. Thereby, the airtightness between the heat insulating panel 10 and the columns 1 and 2 can be ensured.

Further, as shown in FIG. 3, when the heat insulating panel 10 is laid between the studs 2 and 3, the interval b between the end faces of these studs 2 and 3 is relatively large.
(For example, 425 mm), the heat insulating panel 10 is laid between the studs 2 and 3 in an extended state. As in the case of FIG. 2, by fixing the ends of the films 21 and 22 to the columns 1 and 2 by staples, the heat insulating panel 10 is fixed to the columns while ensuring airtightness.

As shown in FIG. 4, these heat insulating panels 1
After the laying of No. 0, the vertical body edge 31 is laid outside the pillars 1, 2, 3 and the exterior material 32 is laid outside the vertical body edge 31 while the inside of the pillars 1, 2, 3 is provided. The interior material 33 is laid, whereby the heat insulation wall using the heat insulation panel according to the present embodiment is completed.

As described above, since the heat insulating panel 10 according to the present embodiment is expandable and contractible, even if the end faces of the through pillar 1 (or the tubular pillar) and the studs 2 and 3 are variously spaced, By expanding and contracting the heat insulating panel 10, the heat insulating panel 10 can be laid in an airtight manner and without heat insulation loss by aligning the end face of the heat insulating panel 10 with the end faces of the columns 1, 2, 3 without any gap. Therefore, unlike the conventional case, there is no need to prepare heat insulating materials of various sizes, and there is no need to perform width addition or width cutting by on-site work, which solves problems such as deterioration in airtightness and heat insulation due to these. it can.

Further, films 21 and 22 are formed on the heat insulating material 11.
Is attached, the films 21, 22 are attached to the columns 1, 2, 3 with staples or the like to fix the heat insulating panel 10, so that the heat insulating panel 10 can be attached with good airtightness.

Further, the concave portions 12 of the concave / convex fitting portions 12 and 13
When b and 13b are fine, the convection of the air stored in the recesses 12b and 13b is prevented, a stationary air layer is formed, and the heat insulation performance can be improved.

The present invention is not limited to the embodiment described above, but can be variously modified. In particular, in the embodiment, the heat insulation panel according to the present invention is used as a heat insulation panel for a wall. However, the heat insulation panel may be used as a heat insulation panel for a floor. It is laid between them. Also, the thermal insulation panel may be used as a roof thermal insulation panel, in which case the thermal insulation panel is laid between rafters. Further, in the heat insulating panel according to the first aspect of the present invention, the film to be attached to the heat insulating material may be provided on at least one side of the heat insulating material, and is not necessarily provided on both sides of the heat insulating material. Further, the number of the halves constituting the heat insulating material is not limited to two, and may be any number as long as it is two or more.

[0035]

As described above, in the present invention, since the heat insulating panel is expandable and contractable, even if the end faces of the structural members of the building, for example, the through pillars, the pipe pillars, and the studs are various, the spacing between the end faces is various. By expanding and contracting the heat insulating panel, the heat insulating panel can be laid in an airtight manner and without any heat insulation loss by aligning the end face of the heat insulating panel with the end face of the structural member without any gap. Therefore, unlike the related art, there is no need to prepare heat insulating materials of various sizes, and there is no need to perform width addition or width cutting by on-site work.
Problems such as deterioration of heat insulation can be solved. Furthermore, since the film or sheet is attached to a structural member such as a pillar with staples or the like to fix the heat insulating panel, the heat insulating panel can be airtightly mounted. Further, convection does not occur in the air stored in the unevenness, and the air layer can exert a heat insulating effect, and does not cause a decrease in heat insulating property.
