Here, as shown in FIGS. 12 and 13, an outer wall panel 3A used in the outer wall panel method includes a vertical frame 4, an upper frame 5, a lower frame 6, and a structural plywood 7 as an outer wall lower cladding.
Is one made with nailing. A rock wool mat 8 mainly serving as a heat insulating material is fitted into the internal space of the outer wall panel 3A, and its ears 8a are fastened to the indoor side surface of the vertical frame 4 with staples 9, 9,. I have.

In the outer wall panel method using the outer wall panel 3A, first, as shown in FIG. 13, the outer wall panel 3A is suspended and placed on the floor joist 10 on the lower floor. Next, the staples 9, 9,... Are removed and the rock wool mat 8 fastened to the indoor side surface of the vertical frame 4 as shown in FIG.
, While hitting the ears 8a of the outer wall panel 3, hit the nails 11, 11,.
A is joined to the floor joist 10. At this time, if necessary,
The nails 11, 11,... Are driven from the vertical frame 4 to the vertical frames of the adjacent outer wall panels built in advance, and the adjacent outer wall panels are joined to each other. Necessary work such as installation of pipes inside the outer wall panel 3A is also performed while appropriately turning over the ends of the rock wool mat 8, and when these works are completed, the ears 8a of the rock wool mat 8 are again removed. The staples 9, 9,. Finally, as shown in FIG. 15, the plaster board 1 as an interior plate is provided on the indoor side surfaces of the vertical frame 4, the upper frame 5, and the lower frame 6.

An outer wall framework is constructed by nailing and integration, and a structural plywood 7 as an outer wall sub-clad is nailed and integrated on the outdoor side to construct an outer wall frame. After performing necessary work such as installation of pipes inside the outer wall skeleton, as shown in FIG. 17, unpacking 8 ′ of a rock wool mat as a heat insulating material wound in a roll shape is performed at the site. It is cut to an appropriate size, and it is pushed into the inner space of the outer wall framework from the indoor side and fastened with staples, nails or the like. Finally, as shown in FIG. 18, the gypsum board 12 as the interior board is brought into contact with the lower frame 6, the vertical frame 4, and the upper frame 5 on the indoor side of the outer wall frame, and nailed and joined.

[0006]

However, in the above-mentioned prior art, the outer wall panel method is used when the outer wall panel 3A is transported from the factory to the site or when the gypsum board 12 is fastened after the outer panel 3A is built. At the stage, the rock wool mat 8 is often wet with rain, which causes quality problems such as causing dew condensation in the wall after completion of the building and generating mold. In addition, rock wool mat 8
Although it is possible to cure the steel so that it does not get wet in the rain, the labor and cost of construction naturally increase significantly in such a case.

Further, in the above-mentioned outer wall panel method, when joining the outer wall panel 3A to the floor joist 10 or the adjacent outer wall panel, the staples 9, 9,... Are removed and the end of the rock wool mat 8 is turned up. If there is no nail 11, 11,
Cannot be driven into the outer wall panel 3A, the staples 9, 9,... Must be removed and the end of the rock wool mat 8 must be turned up when installing pipes and the like inside the outer wall panel 3A. Not very bad. Similarly, when inspecting whether nails 11, 11,... For joining the outer wall panel 3A and the floor joist 10, the adjacent outer wall panel are constructed in accordance with the specifications according to the design document, or inside the outer wall panel 3A. Also, when checking whether or not the pipe or the like is set at a predetermined position, the staples 9, 9,... Must be removed and the end of the rock wool mat 8 must be turned up, which is inefficient. Furthermore, since the staples 9, 9,... Are once removed as described above, before attaching the gypsum board 12, the ears 8a of the rock wool mat 8 are again fastened to the indoor side surface of the frame 4 without waste. Work will occur.

On the other hand, even in the case of the above-mentioned on-site assembling method, the rock wool mat 8 ′ may be wet by rain or humid in the air between the time when the rock wool mat 8 ′ is attached to the outer wall frame and the time when the gypsum board 12 is attached. There is a problem that the quality is deteriorated due to smoking. Further, as shown in FIG. 17, the rock wool mat 8 'wound in a roll shape has a large volume and weight, so that the transportability is poor. Is also bad. In addition, rock wool mat 8 'cut on site
Because the fibrous rock wool is exposed at the end of
There is also a problem that this causes itching on the worker's skin and scatters in the air, seriously affecting the worker's health. In addition, when the space between the vertical frame 4 and the vertical frame 4 is narrow, or when a pipe or the like is set inside the outer wall frame and has a complicated shape, the rock wool mat 8 'is properly placed there. It is very difficult to fill by pushing.

The present invention has been made in view of such circumstances, and has as its object to prevent deterioration in quality due to moisture absorption during transportation and construction, good transportability and workability, and further improvement in workability. An object of the present invention is to propose a heat insulating member and a heat insulating method that do not deteriorate the environment. Further, the present invention utilizes such an advantage of the heat insulating member or the heat insulating construction method, so that the heat insulating material incorporated in the outer wall panel does not get wet when transporting or constructing the outer wall panel, and furthermore, the edge of the heat insulating material. An exterior wall panel that allows the exterior wall panel to be joined to the floor joist and the adjacent exterior wall panel without turning over the exterior wall panel, and an exterior wall panel that uses such an exterior wall panel to improve quality, workability, etc. The purpose is to propose a construction method.

Does not touch the skin of the worker or splatter into the air, thereby harming the worker's health. In addition, since the compression insulation member is reduced in size to a volume smaller than the original insulation material by reducing the pressure inside the waterproof bag body in which the insulation material is sealed, it is easy to transport and requires Packaged with a large volume of insulation,
There is no need for labor such as cutting on site. Furthermore, since the compression insulation member is compact, it can be easily pushed into a space having a complicated shape or a narrow space. If a hole is made in the waterproof bag, the heat-insulated material that has been sealed under reduced pressure expands and returns to its original volume, and at that time, the heat-insulating material expands according to the shape of the space, resulting in a complicated shape. The heat insulating material can be easily filled and constructed even in the inside of a space or a narrow space.

According to a second aspect of the present invention, after the compression heat insulating member of the first aspect is disposed in a predetermined space, a hole is made in a waterproof bag of the compression heat insulating member to expand the heat insulating material. The heat insulating material is filled in the space by the heat insulating material.

In this heat insulation method, a compressed heat insulating member in which the heat insulating material is sealed inside the waterproof bag body is used, so that the heat insulating material does not absorb moisture during transportation or construction, and the quality thereof is not deteriorated. There is no harm to the worker's health by touching the worker's skin or scattering into the air. In addition, the compression insulation member used in this method is reduced in size to a volume smaller than the original insulation material by reducing the pressure inside the waterproof bag body in which the insulation material is sealed. Moreover, since the package is packaged for each heat insulating material having a required capacity, it is not necessary to perform the work such as cutting on site. Furthermore, since the compression insulation member used in this method is compact, it can be easily pushed into a space with a complicated shape or into a narrow space, and then a hole is formed in the waterproof bag. Due to this, the heat-insulating material that has been sealed under reduced pressure expands and returns to its original volume, and at that time, the heat-insulating material expands according to the shape of the inside of the space. Even with this, it is possible to easily fill and construct the heat insulating material.

According to a third aspect of the present invention, in the heat insulating method according to the second aspect, a hole is formed in the waterproof bag body to expand the heat insulating material, and then the hole is closed.

In such a heat insulating method, after a hole is made in the waterproof bag to expand the heat insulating material and then the hole is closed, moisture penetrates through the hole into the waterproof bag after the construction, and Can avoid the situation of moisture absorption and dew condensation, and can ensure the quality of heat insulation construction.

According to a fourth aspect of the present invention, in the heat insulation method according to the third aspect, after the waterproof bag is formed with holes,
Before closing the hole, dry air is injected from the hole.

In such a heat insulating method, after a hole is formed in a waterproof bag, dry air is injected through the hole to close the hole.
It is possible to always maintain a dry state in which the heat insulating material can sufficiently exhibit its original performance, and it is possible to further improve the quality of the heat insulating construction.

The heat insulating material incorporated in the outer wall panel is sealed inside the waterproof bag, so that the outer wall panel does not get wet due to rain when transporting or constructing the outer wall panel.
In addition, the compression heat insulating member is made thinner than the original heat insulating material by reducing the pressure inside the waterproof bag after sealing the heat insulating material. Since they are arranged, there is no hindrance when joining the outer wall panel to a floor joist or the like or installing a pipe or the like inside the outer wall panel, and the workability is good. In addition, since the compression insulation member is thin and does not obscure the joint, it is necessary to check whether the outer wall panel is joined to the floor joists or the like according to the design document, or to locate the piping inside the outer wall panel at a predetermined position. Can be efficiently checked without turning over the end of the compression insulation member. If a hole is formed in the waterproof bag body of the compression heat insulating member with the tip of a tool or the like, the heat-insulated material that has been sealed under reduced pressure expands and returns to its original thickness, and if there is a pipe or the like in the internal space of the frame body. Since the heat insulating material expands so as to enclose it, the outer wall panel in the original form in which the heat insulating material is filled in the inner space of the frame body can be obtained.

Since the compression insulation member inside the frame is arranged with a gap between the interior side surface of the outer wall subboard and the compression insulation member, during the period until the interior plate is attached to the indoor side of the frame body, It is possible to prevent moisture from staying between the waterproof bag and the lower wall of the outer wall due to capillary action or the like, thereby causing condensation in the wall. If a hole is formed in the waterproof bag body of the compression heat insulating member with the tip of a tool or the like, the heat-insulated material that has been sealed under reduced pressure expands and returns to its original thickness, and if there is a pipe or the like in the internal space of the frame body. Since the heat insulating material expands so as to enclose it, the outer wall panel in the original form in which the heat insulating material is filled in the inner space of the frame body can be obtained.

Is expanded, and an interior panel is attached to the indoor side of the frame body.

In the outer wall panel construction method, first, in the first step, the outer wall panel is joined to a preceding frame such as a floor joist. At this time, the heat insulating material is still sealed inside the waterproof bag. Therefore, when transporting or constructing the outer wall panel, it does not get wet due to rain and absorb moisture. In addition, since the compression insulation member is thinner than the original thickness of the heat insulation material and is disposed closer to the outside of the inner space of the frame, the outer wall panel is joined to a floor joist or the like, and piping or the like is provided inside the outer wall panel. There is no hindrance in the work of setting up the work, and the workability is good. In addition, since the compression insulation member is thin and does not obscure the joint, it is necessary to check whether the outer wall panel is joined to the floor joists or the like according to the design document, or to locate the piping inside the outer wall panel at a predetermined position. Can be efficiently checked without turning over the end of the compression insulation member. Then, after necessary work such as installation of pipes inside the outer wall panel is completed, the process proceeds to the second step, in which a hole is made in the waterproof bag body of the compression heat insulating member, and the heat insulating material is expanded, so that the vacuum sealing is performed. The insulating material that had been expanded expands to its original thickness, and if there is a pipe or the like in the internal space of the frame, the insulating material expands to fill the internal space so as to wrap it. If you install an interior board on the indoor side,
The outer wall can be constructed in the original form in which the heat insulating material is filled in the inner space of the frame.

The invention according to claim 8 is characterized in that, in the outer wall panel construction method according to claim 7, a hole is made in the waterproof bag body to expand the heat insulating material, and then the hole is closed.

After sealing inside the waterproof bag 1b made of a polyethylene film or the like, the inside of the waterproof bag 1b is decompressed and air between the fibers in the heat insulating material 1a is sucked to reduce the volume of the heat insulating material 1a. It is made smaller and the whole is compressed.

A method of using the compression insulating mat 1 will be described as an embodiment of a heat insulating method according to the present invention with reference to FIG.

First, as shown in FIG. 1A, a compression heat insulating mat 1 is fixed inside a space A where heat insulation is to be performed.
At this time, since the heat insulating material 1a is sealed inside the waterproof bag 1b of the compression heat insulating mat 1, the quality of the heat insulating material 1a does not deteriorate due to moisture absorption during transportation or construction. It does not harm workers' health by touching the skin or scattering into the air. Further, the compressed heat insulating mat 1 is made compact by reducing the pressure inside the waterproof bag 1b in which the heat insulating material 1a is sealed, so that it is smaller than the original heat insulating material 1a. Even if the space A is narrow or has a complicated shape, it can be easily pushed into it. Moreover, since the compression heat insulation mat 1 is packaged for each heat insulation material 1a having a required capacity, there is no need for trouble such as cutting on site. The position where the compression insulating mat 1 is fixed to the space A is not particularly limited.
The fixing means is appropriately selected from nails, staples, adhesives, adhesive tapes, and the like. In some cases, the compression insulating mat 1 may be simply placed instead of being fixed inside the space A.

Then, as shown in FIG. 3B, when a hole is made in the waterproof bag 1b of the compression insulating mat 1 with an appropriate tool 2, the fibers constituting the heat insulating material 1a are separated from each other. When the air is blown into the space, the heat insulating material 1a expands and returns to its original volume, and at that time, the heat insulating material 1a expands one-dimensionally, two-dimensionally, or three-dimensionally according to the internal shape of the space A. Insulation material 1a inside space A having a small and complicated shape
Can be easily filled. Insulation material 1a
Depending on the type, the degree of compression, and the diameter, number, and location of the holes, merely piercing the waterproof bag 1b may not sufficiently restore the volume of the heat insulating material 1a inside the bag. A suitable fluid, liquid, gas or the like into the waterproof bag 1b.
The volume of the heat insulating material 1a may be forcibly restored by injecting the heat into the inside of the heat sink. In addition, the waterproof bag 1
b, a hole is made in the heat insulating material 1a, and the hole is closed with a tape or a sealing material (not shown) to seal the waterproof bag 1b. As a result, it is possible to reliably prevent the heat insulating material 1a from absorbing moisture and lowering the heat insulating performance. At this time, if dry air is blown into the waterproof bag 1b before closing the hole, the state where the heat insulating material 1a can exhibit its original performance to the maximum can be maintained. Can be improved.

Such a compressed heat insulating mat 1 or a heat insulating method can be applied to any part requiring airtightness and heat insulating property. In particular, as in the internal space of a building wall, ceiling, underfloor, roof, etc. It is effective when used in a space having a small and complicated shape. For example, if this compression heat insulating mat 1 is used instead of the rock wool mat 8 'in the conventional on-site assembly method described with reference to FIGS. 16 to 18, all of the above-mentioned problems pointed out in the method can be solved.

Next, application examples of the compression heat insulating mat 1 and the heat insulating method will be described. FIG. 3 is a perspective view illustrating an embodiment of the outer wall panel according to the present invention. The outer wall panel 3 shown in the figure is a factory-produced panel used for the outer wall of the framing wall construction method, and is an outdoor side of a frame in which the vertical frames 4, 4, 4 and the upper frame 5, the lower frame 6 are integrally nailed. In addition, a structural plywood 7 as an outer wall subboard is nailed and integrated. In the interior space of the outer wall panel 3 surrounded by the vertical frames 4, 4 and the upper frame 5, and the lower frame 6, a compression insulating mat 1 as a compression insulating member fixed to the indoor side surface of the structural plywood 7 is provided. Has been placed.

As described above, the compression insulating mat 1 is made of a fibrous heat insulating material 1 such as rock wool or glass wool.
a is a waterproof bag 1b made of polyethylene film or the like.
After sealing inside, the inside of the waterproof bag 1b is decompressed to suck air between the fibers in the heat insulating material 1a,
This is a mat in which the volume (particularly thickness) of the heat insulating material 1a is reduced. At this time, the thickness of the compression insulating mat 1 is as shown in FIG.
When attached to the indoor side surface of the structural plywood 7 as shown in FIG. It is desirable that it be. As described above, if the thickness of the compression insulating mat 1 is thin, the floor joist 10 and the vertical frame 4 of another preceding outer wall panel 3 ′ are provided on the upper surface of the lower frame 6 and the approximate center of the depth of the side surface of the vertical frame 4. Against nails 11,11,
This is because a space for hitting... Can be secured and workability is good (see FIG. 5). In particular, if the compression insulating mat 1 is compressed in the width direction so that the waterproof bag 1b expands to fill the space between the vertical frames 4 when the holes are made in the waterproof bag 1b, the vertical frame 4 can be expanded. There is no need to prepare a plurality of types of compression insulation mats 1 in accordance with the size of the intervals between the first and second sections, and the time and cost for the insulation can be reduced.

If a hole is formed in the waterproof bag 1b with the tip of the tool 2 or the like, air is blown between the fibers of the heat insulating material 1a inside the mat 1 so that the heat insulating material 1a expands. To the volume (thickness) of the heat insulating material 1a. As described above, depending on the type and the degree of compression of the heat insulating material 1a, the diameter, the number, and the location of the holes, the heat insulating material 1a inside the waterproof bag 1b is merely formed by making a hole.
In some cases, an appropriate fluid, liquid, gas or the like is injected into the waterproof bag 1b to forcibly restore the volume of the heat insulating material 1a. You may.

Next, a method of using such an outer wall panel 3 will be described with reference to FIGS. 4 to 8 as an embodiment of an outer wall panel method according to the present invention.

First, the outer wall panel 3 assembled at the factory and carried to the site is hung by a crane or the like on the installation floor.
As shown in (1), it is placed on the floor joist 10 as the preceding frame. During this time, since the heat insulating material 1a incorporated in the outer wall panel 3 is sealed inside the waterproof bag 1b, it does not get wet due to rain and absorb moisture.

Next, as shown in FIG. 5, nails 11, 11,... Are attached to the floor joist 10 from above the lower frame 6 of the outer wall panel 3.
To join the outer wall panel 3 to the floor joist 10. At this time, since the compression insulating mat 1 is a thin one disposed closer to the outdoor side in the internal space of the outer wall panel 3, the workability is good without hindering the nailing work. When there is an adjacent outer wall panel 3 'built in advance, the nails 11, 11 are attached to the vertical frame 4' of the outer wall panel 3 'from the side of the vertical frame 4 of the outer wall panel 3. , ..., the outer wall panels 3, 3 'are joined to each other. Also at this time, the compression insulating mat 1 does not hinder the nailing work, and the workability is good. Since the heat insulating material 1a is still sealed in the waterproof bag 1b, the heat insulating material 1a does not get wet due to rain and absorb moisture.

In this manner, necessary outer wall panels 3,
When all the 3 ′,... Are joined to the floor joist 10 and the joint work of the adjacent outer wall panels 3, 3 ′,... Is completed, pipes are passed through the inside of the outer wall panels 3, 3 ′,. Perform necessary work such as installing And
Even in such a case, since the compression insulating mat 1 is thin, it does not hinder the work. Insulation material 1a is waterproof bag 1
It is the same as the above in that it is sealed in b and does not absorb moisture due to rain.

Further, it is checked whether or not the outer wall panels 3, 3 ',... Are joined to the floor joist 10 or the adjacent outer wall panel according to the design document.
It is checked whether necessary pipes pass through predetermined positions inside 3 ',.... Also in this case, since the compression insulation mat 1 is thin and does not cover the nails 11, 11,... It is the same as above in that the heat insulating material 1a is sealed in the waterproof bag 1b and does not absorb moisture due to rain.

In this way, the outer wall panels 3, 3 ',.
When the preparation for attaching the gypsum board 12 as the interior board is completed, an appropriate hole is made in the waterproof bag 1b of the compression insulating mat 1 with the tip of the tool 2 as shown in FIG. Then, air is drawn into the space between the fibers of the heat insulating material 1a inside the waterproof bag 1b from the holes, and as shown in FIG. That is, it expands until the thickness of the vertical frame 4 becomes substantially equal to the thickness of the vertical frame 4 and fills the entire inner space of the outer wall panels 3, 3 ',. In addition, piping and the like (not shown)
When arranged in the internal space of 3 ′,..., The compression insulating mat 1 fills the entire internal space of the outer wall panels 3, 3 ′,.

Then, from the hole made in the waterproof bag 1b,

Then, the dry air spreads between the fibers of the heat insulating material 1a inside the waterproof bag 1b, and the heat insulating performance of the heat insulating material 1a is maximized. Further, in this state, if the waterproof bag 1b is sealed by closing the hole with an appropriate tape, sealing material, or the like, moisture enters the inside of the waterproof bag 1b from the hole, and the heat insulating material 1a absorbs moisture. It is possible to perform high-quality heat insulation construction that maximizes the heat insulation performance of the heat insulating material 1a.

Finally, as shown in FIG. 8, the gypsum board 1 as an interior board is provided on the indoor side surfaces of the vertical frame 4, the upper frame 5, and the lower frame 6.
2 may be nailed with nails 11, 11,. In this manner, if the compressed and heat-insulated mat 1 that has been decompressed and compressed is expanded just before the gypsum board 12 is attached to the outer wall panel 3, the compressed and heat-insulated mat 1 is transported or built when the outer wall panel 3 is transported.
Can be easily returned to the original state in which the inner space of the outer wall panel 3 is filled with the heat insulating material.

The present invention is not limited to the above embodiment, and various modifications can be made in view of the gist of the invention. For example, the compression insulating mat 1 ′ incorporated in the inner space of the outer wall panel 3B shown in FIG. 9 has a waterproof bag 1b divided into a plurality of air chambers. 1a is enclosed and compressed under reduced pressure. Here, the air chambers may be in a form in which they communicate with each other.

The outer wall panel 3C shown in FIGS. 10 (a) and 10 (b) contains the compressed heat insulating mat 1 in a form fixed to the indoor side surface of the structural plywood 7 like the outer wall panel 3. , Small pieces of packings 13, 13,... Are attached to the indoor side surface of the structural plywood
The compression insulating mat 1 is fixed to 3, 13,. Examples of the material of the packing 13 include, but are not limited to, rubber, styrene, and wood. In the outer wall panel 3C, since a gap is secured between the compression insulation mat 1 and the outer wall lower cladding 7, the compression insulation mat is expanded until the gypsum board 12 is attached by expanding the compression insulation mat 1. It is possible to prevent the water from staying between the inner wall 1 and the outer wall lower cladding 7 due to a capillary phenomenon or the like, thereby causing dew condensation in the wall. This gap is the waterproof bag 1
If a hole is made in b, and the compression insulating mat 1 is expanded, it will be closed as shown in FIG. Packing 13
May be arranged such that long packings 13, 13,... Are arranged side by side at predetermined intervals as shown in FIG. In addition, from the viewpoint of the workability described above, the packing 13 is made as thin as possible, and the floor joist 10 and the other preceding outer wall panel 3 are placed on the upper surface of the lower frame 6 or the substantially central portion of the side surface of the vertical frame 4 in the depth. It is desirable to secure a space for hitting the nails 11, 11,... With respect to the 'vertical frame 4'.

The outer wall panel 3 shown in FIG.
D differs from the outer wall panel 3C in that the compression insulating mat 1 accommodated in the internal space has the ear 1c. When a hole is made in the waterproof bag 1b of the compression insulating mat 1 of the outer wall panel 3C, the heat insulating material 1a expands three-dimensionally, and the ear 1c is just vertically framed as shown in FIG. 4 comes into contact with the indoor side surface. Therefore, the ear 1
c can be fixed to the indoor side surface of the frame 4 with staples or the like, and the workability is good.

In addition, in the above embodiments, the shape, material, dimensions, etc. of the frame composed of the vertical frame 4, the upper frame 5, and the lower frame 6, the outer wall lowering board, the interior board, and the like are determined as appropriate. It goes without saying that this can be done.

Furthermore, since the compression insulation member can be easily pushed into the inside of a space having a complicated shape or the inside of a narrow space, and can be easily returned to the original volume, the quality and workability of the insulation work can be improved.

Further, according to the outer wall panel and the outer wall panel method according to the present invention, the heat insulating material incorporated in the outer wall panel does not get wet and absorb moisture when transporting or constructing the outer wall panel. No quality problems such as mold generation due to dew condensation inside the wall after the completion of the building. In addition, the workability is good because the heat insulating material does not hinder the work of joining the outer wall panel to the floor joist or the like, or installing piping or the like inside the outer wall panel, or the inspection and confirmation thereof. Nevertheless, when necessary, the heat insulating material can be easily returned to the original form of the outer wall panel in which the inner space of the frame is filled.
