Description

[Detailed description of the invention]

[0001]

[Technical field of the invention] The present invention has a heat insulating panel for a paneling method of a heat insulating wall of a wooden frame construction method.
The present invention relates to a hermetic and heat-insulating structure of a building having significantly improved hermeticity.

[0002]

[Technical Background of the Invention] In detached houses and the like, in recent years, in order to improve indoor airtightness and heat insulation, a heat insulating material such as expanded polystyrene is often used for outer walls and the like. When laying an outer wall having such a heat insulating material, a wooden frame construction method using a plywood which receives horizontal force instead of structural members such as bracing and a heat insulating panel comprising a heat insulating material attached to the plywood is used. In some cases, a paneling method for insulating walls may be adopted. Accordingly, there is an advantage that the laying of structural members such as bracing can be omitted, the construction period can be shortened, and the cost can be reduced by the integrated production of heat insulating panels.

In adopting such a construction method, the inventor of the present invention maintains the temperature of the plywood at substantially the same temperature as that of the room without cooling the plywood even if the humidity inside the high-temperature and high-humidity room reaches the plywood. From the viewpoint of preventing dew condensation of moisture and corrosion of the plywood, a heat insulating material is attached to the outside of the plywood. However, when attaching the heat insulating panel to a structural member such as a pillar, the end of the plywood of one heat insulating panel is abutted against the end of the plywood of the adjacent heat insulating panel, and the ends of these plywood are nailed. It is fixed to pillars. Therefore, since it is necessary to secure a place for hitting the nails or the like, no heat insulating material for the heat insulating panel is provided outside the ends of these plywoods, that is, at the portion corresponding to the outside of the pillar. Therefore, there is a problem that airtightness and heat insulation cannot be sufficiently obtained in these portions. In addition, pillars,
Beams and the like deteriorate over time, bending, thinning,
When deformation such as shrinkage occurs, the tendency is more remarkable. Therefore, there has been a problem that the airtightness and the heat insulating property cannot be sufficiently obtained even though the airtightness and the heat insulating property of the building are conventionally maintained by using the heat insulating panel.

[0004]

[Purpose of the Invention] The present invention has been made in view of such circumstances, and in using heat insulation panels,
The airtightness of buildings that can provide sufficient airtightness and heat insulation
It is to provide a heat insulating structure.

FIG. 1 is a perspective view of a detached house to which an airtight and heat-insulating structure for a building according to an embodiment of the present invention is applied. FIG. 2 is a cross-sectional view of an outer wall to which an airtight and heat-insulating structure according to an embodiment of the present invention is applied. FIG. 3 is an enlarged sectional view of a main part of the present invention of FIG. FIG. 4 is a cross-sectional view of the heat insulating panel used in this embodiment.

First, a heat insulating panel 1 used in this embodiment will be described. As shown in FIGS. 1, 2, and 4, the heat insulating panel 1 includes a plate-shaped member 2 serving as a structural member between columns, an outer heat-insulating material 3 located outside the plate-shaped member 2, and a plate-shaped member 2. And a stud 4 attached to the center of the inside.
As described later, the plate-like member 2 includes columns (through columns 10, tube columns 1).
1) Acts as a structural member that receives a horizontal force between them. This can eliminate the need for bracing or the like. Therefore, the plate member 2 is, for example, a plywood.

The outer heat insulating material 3 is a heat insulating material made of a synthetic foamed resin such as expanded polystyrene or expanded polyurethane, and its expansion ratio is arbitrary, for example, 20 to 60 times. However, a fibrous heat insulating material such as glass wool may be used. The outer heat insulating material 3 is attached to the plate member 2 with an adhesive or a nail. The stud 4 functions as a structural member that receives a normal force. This stud 4
Are fixed to the plate-shaped member 3 in advance by nails or the like.

The heat insulating panel 1 configured as described above is
It is laid as shown in FIGS. That is, as shown in FIG. 1, a base 9 is provided on a foundation 8, and this base 9
On top of this, a through column 10 and a tube column 11 are provided. A body gap 12 and a girder 13 are stretched over these pillars 10 and 11.
The stud 4 of the heat insulating panel 1 is fitted between the base 9, the gap 12 and the girder 13, and the peripheral end of the plate-like member 2 of the heat insulating panel 1 is fitted with the base 9, the pillars 10 and 11, and the gap 12. , Digit 13
Is fixed with a nail 21 (see FIG. 3) or the like. Thereby, the installation of the heat insulating panel 1 is completed. Further, as shown in FIG. 2, a vertical trunk edge 14 is provided outside the end of the plate-shaped member 2 of the heat insulating panel 1 and outside the outer heat insulating material 3, and an exterior material 15 is laid outside this. On the other hand, the airtight moisture-proof sheet 16 and the interior material 17 are laid inside the pillars 10 and 11 and the stud 4.

In the present embodiment, as shown in FIGS. 1 and 2, and particularly as shown in an enlarged manner in FIG. Between the two outer heat insulating materials 3 of the two heat insulating panels 1, a long heat insulating supplement material 20 made of a hard foamed resin is provided, and an airtight tape 30 is provided outside these materials. . When attaching the heat-insulating supplement 20 or the like, the heat-insulating supplement 2
0 is inserted between the ends of the outer heat insulating material 3 of the heat insulating panel 1 and filled, and then an airtight tape 30 is attached to the outside of the heat insulating supplement 20 and the end of the outer heat insulating material 3. Further, outside the airtight tape 30, the above-mentioned vertical waist edge 14 is attached to the nail 3.
1 (FIG. 3).

The heat insulating supplement 20 is formed from a hard foamed resin. This is because, firstly, it is necessary to ensure airtightness and heat insulation, and secondly, it is necessary to attach the vertical waist edge 14 with nails 31 (FIG. 3). This is because if formed from resin, the heat-insulating supplement 20 may be crushed. Examples of the rigid foamed resin forming the heat insulating supplement material 20 include foamed polystyrene, foamed polyurethane, foamed polyethylene, foamed polypropylene, and the like.
The expansion ratio in the case of expanded polystyrene is 20 to 6
0, and the expansion ratio in the case of foamed polyurethane is 2
It is 0 to 50 times.

Further, the heat-insulating supplement material 20 is formed in a rectangular cross section and has a constant cross section, and is formed in a long shape as shown in FIG. From the viewpoint of work efficiency, it is preferable to form one unit, but it may be formed of a plurality of units. Conventionally, when the outside heat insulating material is not provided at the end of the plate-shaped member 2, that is, at the place where the plate-shaped member is attached to the column 11, sufficient airtightness and heat insulation cannot be obtained. In this embodiment, since the heat-insulating supplementary material 20 is provided in this manner, the airtightness and the airtightness are obtained at the end of the plate-shaped member 2, that is, at the place where these plate-shaped members are attached to the columns 11. It is possible to obtain sufficient airtightness and heat insulation without deteriorating the heat insulation. Also, compared to a method of providing airtightness and heat insulation by filling a caulking material at these attachment points, the work efficiency is extremely high and simple work can be completed. Furthermore, since the heat-insulating supplement 20 is formed from a hard foamed resin, the vertical body edge 14 can be nailed to the outside of the heat-insulating supplement 20, and there is an advantage that there is no problem in terms of structure. .

Further, in the present embodiment, the heat insulating supplement 2
An airtight tape 30 is stuck to the outside of the outer heat insulating material 3 at 0. The airtight tape 30 may be coated with an adhesive beforehand, or may be bonded with an adhesive not coated with an adhesive. The hermetic tape 30 can further improve the hermetic performance around the heat insulating supplement 20. Examples of the airtight tape 30 include soft urethane foam, soft vinyl chloride, and asphalt impregnated tape.

Further, the configuration in which the heat-insulating supplementary material 20 and the airtight tape 30 are provided includes the heat-insulating panel 1 and the pillar 11.
As shown in FIG. 1, not only is applied to the mounting position between the base 9 and the heat insulating panel 1, but also to the mounting position between the body gap 12 and the heat insulating panel 1, and between the girder 13 and the heat insulating panel 1. It is needless to say that the present invention may be applied to a mounting portion and a mounting portion between a beam and a heat insulating panel. Also in these cases, sufficient airtightness and heat insulation can be obtained.

Further, the heat insulating supplement 20 may be configured as shown in FIG. That is, the insulation supplement 20
Slits 22 extending in the longitudinal direction may be formed on the upper and lower surfaces of both side portions. The slits 22 are preferably formed alternately on the upper and lower surfaces as shown in FIG. The width of the slit 22 is preferably about 0.5 mm to 1.5 mm. Since the slits 22 are provided in this manner, as shown by an arrow A in FIG. 5, even if the heat insulating supplementary material 20 is a hard foamed resin, the heat insulating supplementary material 20 is shrunk, as shown in FIG. It can be easily inserted between the ends of the outer heat insulator 3. After the insertion, the heat-insulating supplement 2
Since 0 expands and presses the end of the outer heat insulating material 3, the airtightness and the heat insulating property can be further improved. An example of the heat-insulating supplementary material 20 in which such slits are formed is Kanelite Foam Inserter (Kanebuchi Chemical Industry Co., Ltd.).

Although the embodiment of the present invention has been described, the heat insulating panel 1 used in the present invention can be variously modified. For example, as shown in FIG. 6, the heat insulating panel 1 has not only the stud 4 at the center of the plate member 2 but also the plate member 2.
May also be provided with an end post 4a. further,
As shown in FIG. 7, the heat insulating panel 1 may be configured so that the width thereof is not a half but a quarter. Also in this case, the stud 4 is attached to the plate-like member 2. Further, as shown in FIG. 8, the heat insulating panel 1 is configured to have a width of 1/4 as in the case shown in FIG. 5, and the stud 4 may not be provided.

Further, in the above-described embodiment and the modified example, the outer heat insulating material 3 is provided outside the plate-shaped member 2, but as shown in FIGS. ,
Inner heat insulator 5 made of the same material as outer heat insulator 3
May be provided. In this case, the inner heat-insulating material 5 plays a role of heat-insulating reinforcement, whereby the heat-insulating effect around the plate-like member 2 is further improved. This will be further prevented. Specifically, as shown in FIG. 9, the inner heat insulating material 5 is attached to the inside of the plate-like member 2 of the heat insulating panel 1 which is the same as that shown in FIG. Further, as shown in FIG. 10, an inner heat insulating material 5 is attached to the inside of the plate-shaped member 2 of the heat insulating panel 1 which is the same as that shown in FIG. Further, FIG.
As shown in FIGS. 1 and 12, also in the heat insulating panel 1 of 1/4, the inner heat insulating material 5 is similarly attached inside the plate-shaped member 2. Thus, in various heat insulation panels 1,
An inner heat insulating material 5 may be provided.

The present invention is not limited to the embodiment described above, but can be variously modified. In particular, matters that are not limited in the specification can be variously modified.
