DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-like heat insulating member used in a building and a heat insulating method using the same.

[0002]

2. Description of the Related Art In recent years, from the viewpoint of energy saving, the entire detached house has been actively surrounded by a heat insulating material.

FIG. 5 shows a heat insulation structure in the back of a hut in a conventional wooden house.

In this building, a rafter receiver 5 is arranged on the eaves girder 4 so as to support a roofing material 1 such as a tile, a field board 2 and a rafter 3, and a main house 7 on a shed 6.
Is assembled. In addition, hut zuka 6 is hut back A
In the inside, it stands on the hut beam 8 at predetermined intervals.

In such a building, when insulating the inside of the cabin A, that is, the interior of the room B, the plate-shaped heat insulating members 9 are laid flat on the cabin back A so as to be flush with the upper surface of the eaves girder 4. Have been.

On the other hand, in this building, an external heat insulating structure is formed by arranging a heat insulating material 10 outside the pillar in a plane direction. The external insulation structure has the advantage that there are few thermal bridges.

[0007]

When the plate-shaped heat insulating member 9 is laid in the back of the hut A in this manner, the plate-shaped heat insulating member 9 formed in a substantially rectangular shape is vertically and horizontally separated without any gap. I have to arrange them. On the other hand, since the huts 6 are erected at substantially equal intervals in the hut back A, the huts 6 come into contact with the hut 6 when the plate-shaped heat insulating member 9 is laid. For this reason, conventionally, the contact with the shed 6 has been dealt with by cutting out a part of the plate-shaped heat insulating member 9 which is in contact with the shed 6 at the site.

However, in the field, the heat insulating material 9
Not only is a great deal of labor for the operator to cut out, but if the cutout is not cut to size, a gap is formed between the shed and the shed 6. As a result, There is a problem that the heat insulation performance is reduced even though the external heat insulation is applied. In addition, the improvement of the notch work of the heat insulating material in relatively high places has been demanded in order to ensure safety.

The present invention has been made in view of such circumstances, and particularly in a wooden house, for example, when building a heat insulating structure on a girder, a plate used in a building in which a plate heat insulating member can be easily arranged. It is intended to provide a heat insulating member.

[0010] The present invention also provides a heat insulation construction method for a building in which a heat insulation structure can be easily and safely constructed by laying a plate-like heat insulation member on a girder. It is intended to be.

[0011]

According to the present invention, there is provided a plate-like heat insulating member for a building, which is laid in a substantially horizontal state on a floor surface or the back of a shed. The plate-shaped heat-insulating member has a substantially rectangular shape, and notches are formed at four corners thereof in advance. Further, the notch may be formed at the center of at least one side in addition to the four corners. This side may be either a long side or a short side. Of course, it may be formed on both sides.

According to the present invention having such a configuration, it is not necessary to cut out the plate-like heat insulating members on site, and it is sufficient to simply lay the plate-like heat insulating members in a plane, thereby contributing to workability. it can. In addition, it is preferable that the size of the plate-shaped heat insulating member according to the present invention is set to be substantially the same as the interval between the huts erected on the girder.

If the size is set in advance,
It can be laid easily on site.

Further, the plate-like heat insulating member according to the present invention is characterized by comprising a synthetic resin foam and a reinforcing face material disposed on at least one side of the foam.

With such a structure, the surface strength of the plate-shaped heat insulating member can be improved. The synthetic resin foam and the reinforcing face material are integrated in advance. Thus, the foam and the reinforcing face material can be laid at the same time.

Further, the reinforcing face material may be a veneer, a plywood,
Preferably, it is either a fiber board or a particle board.

By providing such a reinforcing face material, the bending rigidity of the foam can be particularly increased.

The heat insulation method according to the present invention is a heat insulation method for constructing a heat insulation structure on a girder of a building, wherein the plate heat insulation member is provided with a notch at a position corresponding to a standing portion of a hut. Are arranged between the huts on the girder, and a heat insulating supplementary plate made of a foamed synthetic resin is fitted into the cutout portion where there is no hut to cover the gap.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows a plate heat insulating member according to an embodiment of the present invention, and FIG. 2 shows an example of use of the plate heat insulating member.

The plate-shaped heat insulating member 11 is made of a foamed synthetic resin and has a size of, for example, 910 × 1820 mm.

Notches 12 are formed at four corners of the plate-shaped heat insulating member 11 made of a synthetic resin foam. The size of the cutout portion 12 is, for example, a size corresponding to the diameter of the shed 6 standing upright on the back of the shed. For example, when the shed 6 is 90 × 90 mm, That is, it is 45 × 45 mm. Also,
In this plate-shaped heat insulating member 11, cutouts 13 are formed at the centers of the long sides on both sides, respectively. The size of the notch 13 is, for example, 45 × 90 mm for the same reason. However, since the foamed synthetic resin is deformable and can be compressed from both sides, the cutout dimension is set to be two to two times smaller than the actual dimension.
It is also possible to reduce the size by about 5 mm and cut it out, for example, to a size of about 43 × 88 mm. The small cutout allows the hut to be inserted in a compressed state, for example, on the side surface of the shed 6 or the like.

On the other hand, the thickness of the plate-shaped heat insulating member 11 can be appropriately set according to the desired heat insulating performance.

Such a plate-like heat insulating member 11 is, for example,
As shown in FIG. 2, it can be preferably used as a heat insulating material laid behind a hut in a wooden house.

That is, on the back of the hut, as in the case of FIG. 5 showing the conventional example, huts 6 are arranged at predetermined intervals. The plurality of sheds 6 support the roof material above.

In such a wooden house, if the plate-like heat insulating members 11 are arranged so as to be interposed between the huts 6 or 6 in order, the plate-like heat insulating members 11 can be laid on the entire back of the hut. Insulation can be applied. Moreover,
In this case, the butted portions of the plate-shaped heat insulating members 11 come into contact with each other, so that heat insulation loss does not occur.

As shown in FIG. 2, when the shed 6 is not provided upright in the cutouts 12 and 13 formed in advance, heat insulating supplements corresponding to the sizes of the sheds 6 are provided in the cutouts. What is necessary is just to press-fit the material 17. Insulation supplement 17
Is preferably prepared in advance of a predetermined size. If the heat insulating supplementary material 17 is formed to be slightly larger than the size of the cutouts 12 and 13, it will be slightly swelled by being compressed and pushed, so that the generation of a gap can be reliably prevented.

In the present invention, since the plurality of plate-shaped heat insulating members 11 in which the notches 12 and 13 are formed in advance are laid so as to surround the hut or the shed 16, there is no need to cut out the heat insulating material on site. . Therefore, a heat insulating structure can be easily constructed. Further, since the notch work is not required, it contributes to the safety of the worker and the workability is further improved.

The foam constituting the plate-shaped heat insulating member 11 may be composed of any foam, for example, polystyrene foam, polypropylene foam, polyethylene foam, polyurethane foam, phenol foam, acrylic foam, carbonate Examples include inorganic foams, hydroxide-based inorganic foams, carbonate-based inorganic foams, and silicate-based inorganic foams. Organic foams such as polystyrene foam and polypropylene foam are preferred when workability based on lightness is to be enhanced, and inorganic foams are preferred when nonflammability is important. These foams can be produced by an extrusion method or a bead method for an organic foam, or a batch method for an inorganic foam. Although the expansion ratio is arbitrary, for example, 20 to 6
It is desirable to make it 0 times.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

For example, in the above embodiment, the plate-shaped heat insulating member 1
Although 1 is made of the foam itself, this plate-shaped heat insulating member may be made of a laminate like a panel. That is, as in the case of the plate-shaped heat insulating member 25 shown in FIG. 3, for example, the reinforcing face materials 21 can be laid on both surfaces of the foam 11a. Of course, the reinforcing face material 21 can be provided only on one side. When the reinforcing face material 21 is provided only on one side, it is preferable that the reinforcing face material 21 is disposed on the lower surface side. When the reinforcing surface material 21 is laid on one side or both sides,
Since the second moment of area increases, as a result, it is possible to provide such a strength that a person can ride on it like a scaffold. However, when a person does not walk on this, the thickness of the reinforcing face material 21 may be about 1 to 7 mm. Therefore, even if the face material is laid, the whole is lightweight, and the workability in the construction is not reduced. The reinforcing face material 21 is not particularly limited as long as it has appropriate strength. For example, veneer, plywood, fiber board, wood-based material such as particle board, polyethylene terephthalate, sheet such as polycarbonate, Examples thereof include organic materials such as films and polypropylene hollow laminates, paper-based materials such as kraft paper and liner paper, and composite materials such as paper-based unsaturated polyester resin impregnated plates. Further, the type may be different for each side.

For joining the foam 11a and the reinforcing face material 21, for example, an adhesive is used. Examples of the type of the adhesive include a vinyl acetate resin emulsion-based adhesive, an epoxy-based adhesive, and a urethane-based adhesive. Further, the foam body 11a and the reinforcing face material 21 may be connected by a needle material such as a stapler, but since penetration of a metal such as a needle causes heat insulation loss, it is necessary to prevent penetration.

Furthermore, the reinforcing face material 21 and the foam 11a can be separately installed on site without being laminated in advance like a panel. Further, the corners of the reinforcing face material 21 may be cut off at the site. Further, in the above embodiment, one plate-shaped heat insulating member 11 is arranged on the upper part of the hut beam 17,
Two plate-shaped heat insulating members 11 can be stacked.

As in the case of the plate-like heat insulating member 26 shown in FIG. 4, the notch 12 may be formed only at the four corners, and the notch 13 may not be formed at the center of the long side. In short, it is only necessary to cut out in advance the location of the foam that comes into contact with the vertical member of the wooden house. Therefore, in some cases, in addition to the four corners, the center of the short side can be cut out, and the center of the long side can be cut out on only one side. The location and number of cutouts are not limited to the embodiment. in this way,
By notching in advance, it is possible to contribute to improvement of workability at the site.

The plate-like heat insulating members 26, 2
5 and 11 are not limited to being used as a heat insulating material in the back of a hut, and can be used, for example, as heat insulating materials for floors.
In this case, the portion corresponding to the pillar may be cut out.

[0037]

As described above, according to the plate-like heat insulating member used in the building according to the present invention and the heat insulating method using the same, it is necessary to cut off the corners of the heat insulating material on site. Since there is no heat insulating member, the plate-shaped heat insulating members can be easily laid and arranged, and the workability is improved. Further, when used in the back of a hut, work at high places is reduced, which can contribute to enhancing safety. Further, since a supplementary heat insulating material is prepared and buried in a notched portion that is no longer required, there is no occurrence of a cutout defect.
