DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural panel body having excellent air-tightness and thermal insulation for use in a wooden building.

[0002]

2. Description of the Related Art In a wooden construction method, a room is kept in order to save energy required for cooling and heating and to provide a comfortable living space so that air and moisture in a room do not move freely behind a wall or under a floor. A high airtight and high heat insulation method has been implemented in which a moistureproof airtight sheet having moistureproof airtight performance is attached to all of the constituent floors, ceilings, and wall surfaces, and ventilation is systematically performed for 24 hours with airtight performance provided. .

[0003]

In such a highly airtight and highly heat-insulated construction method, the installation of the moisture-proof airtight sheet is performed on all the floors, ceilings, and outsides of the walls constituting the room, and the installation is complicated and troublesome. Thus, there is a problem that the moisture-proof airtight sheet is easily damaged during the construction, and the airtightness is deteriorated if a scratch or a hole is made in any one place.

[0004]

In order to solve the above problems, the present inventor has determined that a moisture-proof air-tight sheet having a moisture-proof performance equal to or higher than that of a state in which a moisture-proof airtight sheet has been constructed, and reducing the time and labor required for construction on site. As a result of intensive studies, the present inventors have reached the present invention.

That is, according to the present invention, a vertical frame and a horizontal frame provided with a groove extending in the longitudinal direction of one surface are provided with a panel frame body having the groove formed on the inner surface, and an aluminum frame provided on at least one surface of the wooden substrate. With the layer as the core layer, a paper layer on one side,
A laminate in which a synthetic resin film layer is laminated on the other side is made of a moisture-proof and airtight plate adhered so that the paper layer is in contact with the wooden substrate, and the four peripheral edges of the moisture-proof and airtight plate are in the grooves of the panel frame. It is a building panel body fitted and fixed.

[0006]

According to the present invention, a laminate in which an aluminum layer is used as a core layer, a paper layer is laminated on one side and a synthetic resin film layer is laminated and integrated on the other side, and the paper layer is bonded to a wooden substrate. By being attached, it has the same or better moisture-proof performance as the moisture-proof airtight sheet used in the high airtight and high heat insulation construction method, and also has excellent heat insulation performance. By using the building panel body fitted and fixed in the groove as a panel of a wooden building, it is possible to omit the construction of the moisture-proof airtight sheet outside the building panel body.

[0007]

FIG. 1 shows an example of an architectural panel body according to the present invention, in which a vertical frame 1a, 1b and a horizontal frame 2a, 2b in which a groove 7 is formed over the entire surface in the longitudinal direction. The body 3 is constituted. When the panel frame 3 is formed, each of the vertical frames 1a, 1b and the horizontal frame 2 is formed such that the groove 7 is continuous at the joint of the vertical frame and the horizontal frame on the inner surface of the panel frame 3.
The positions of the grooves 7 to be formed in a and 2b are determined.

Further, the four peripheral edges of the moisture-proof airtight plate 4 are fitted and fixed in the grooves 7 to form a building panel body. Also, in order to increase the strength of the panel frame 3, middle bars 6a and 6b can be provided as shown in FIG. The incorporation of the middle crosspiece is not limited to the shape shown in FIG. 1, and a plurality of horizontal crosspieces, a plurality of vertical crosspieces, a middle crosspiece provided in a lattice shape, or an arbitrary shape can be incorporated.

In order to enhance the heat insulating performance, a heat insulating plate 5 can be laminated inside the single-sided panel frame 3 of the moisture-proof airtight plate 4. Further, if necessary, the heat insulating plate can be laminated on both sides of the moisture-proof airtight plate 4.

FIG. 2 shows an example of the moisture-proof airtight plate 4 of the present invention. A laminate S having an aluminum layer 10 as a core layer, a synthetic resin film layer 11 on one side and a paper layer 9 on the other side, in a state where the paper layer 9 is adhered so as to be in contact with one side of the wooden substrate 8. 4 shows a moisture-proof airtight plate 4.

The wood substrate 8 constituting the moisture-proof airtight plate of the present invention
For example, plywood, wood chipboard, wood fiber board, and veneer laminate may be used alone or in any combination.

As the paper layer 9 of the laminate S to be adhered to the wooden substrate 8, kraft paper, tissue paper, recycled paper, or the like can be used. Since the paper layer 9 is disposed, the anchoring effect of the paper layer 9 and the adhesive easily penetrate into the paper layer 9,
It is possible to sufficiently secure the adhesive strength when the laminate S is attached to the wooden substrate 8.

Further, as the synthetic resin film layer 11,
Synthetic resin films such as polyester, polystyrene, polycarbonate, hard vinyl chloride, polypropylene, and polyethylene terephthalate can be used. The synthetic resin film having a thickness of 10 μm or more can be used.

Preferably, those having a thickness of 10 to 30 μm are used. If the thickness of the synthetic resin film is less than 10 μm, sufficient moisture-proof performance cannot be obtained even when an aluminum layer is vapor-deposited. And only the cost is increased, which is not preferable.

In the present invention, these synthetic resin film layers 11
Used is a layer in which an aluminum layer 10 is laminated. As the aluminum layer 10, an aluminum foil or a material obtained by evaporating aluminum on one surface of a synthetic resin film layer 11 can be used. 10 μm when using aluminum foil
Use the above.

On the other hand, in the case of aluminum vapor deposition, since the composite moisture-proof performance of the aluminum layer and the synthetic resin film is exhibited, a vapor-deposition amount of 400 ° can exhibit the same moisture-proof performance as aluminum foil of 10 μm.

For this reason, aluminum deposition is preferred. Aluminum deposition is, for example, 10 ⁻⁴ mmHg
By heating aluminum to a temperature above its melting point under a moderately high vacuum, the aluminum is vaporized and scattered. By exposing the cooled synthetic resin film to the vapor, the aluminum vapor adheres to the surface of the synthetic resin film and solidifies with molecular fine particles.

According to such a method, a very thin aluminum coating can be applied to the surface of the synthetic resin film layer 11.

The thickness of the aluminum layer 10 deposited on the synthetic resin film layer 11 in the present invention is from 400 ° to 8 mm.
Preferably, it is formed to a thickness of 00 °. With a layer thinner than 400 °, the moisture-proof performance required in the high airtightness and high heat insulation method cannot be sufficiently exhibited. Further, even if the aluminum layer 10 is formed thicker than 800 °, the moisture-proof performance is not further improved.

Among the above synthetic resin film layers 11, polyethylene terephthalate, in particular, has a water vapor transmission rate of 40 g / m ² 24 h for a sheet having a thickness of 12 μm by itself.
Although it is easy to pass water vapor as high as r or more, vapor deposition of aluminum can significantly reduce the water vapor transmission rate.

That is, compared to a resin sheet having a lower water vapor transmission rate than polyethylene terephthalate in a single sheet state, the polyethylene terephthalate sheet has a lower water vapor transmission rate when an aluminum layer having the same thickness is formed. Lower. For this reason, a sheet that is thinner than other resins can exhibit sufficient moisture-proof performance, which is particularly preferable.

The laminate S is formed by attaching an aluminum layer 10 deposited on the synthetic resin film layer 11 and a paper layer 9 to each other. The paper layer 9 is adhered by heat fusion with a synthetic resin sheet such as polyethylene, vinyl chloride, or polypropylene interposed therebetween, or is adhered using an adhesive. (Not shown)

As an example of sticking by heat fusion, a polyethylene sheet is laminated on a paper layer 9, a synthetic resin film layer 11 on which aluminum is deposited is further laminated, and the whole is heated and pressed to form a polyethylene sheet. It can be fused and attached.

The heating temperature in the thermocompression bonding must be lower than the melting temperature of the synthetic resin film layer 11. This is because if the synthetic resin film layer 11 is melted by thermocompression bonding, the moisture-proof performance improved by aluminum evaporation is reduced.

For this reason, the aluminum layer 1 is heat-sealed.
It is preferable to select a synthetic resin sheet that is lower than the melting temperature of the synthetic resin film layer 11 as the synthetic resin sheet used to attach the paper layer 9 to the sheet material 9.

As described above, by sticking by heat fusion, the polyethylene resin is stuck to the middle of the paper layer 9 in a state of being permeated and hardened.

In the case of sticking using an adhesive, the sticking can be performed using a urea resin-based, phenolic resin-based, melamine resin-based, vinyl acetate resin-based, or vinyl urethane resin-based adhesive. The laminate S attached by any of the methods also has the paper layer 9 on the side where the paper layer 9 is adhered to the aluminum layer 10.
The adhesive used for the attachment or the resin in which the synthetic resin sheet has melted has a permeated portion that penetrates into the paper layer 9.

Further, the moisture-proof airtight plate 4 of the present invention is obtained by sticking the laminate S to the wooden substrate 8, and the sticking of both is performed via an adhesive. The adhesive used at this time is the paper layer 9 and the aluminum layer 10 of the laminate S.
The same adhesive as the adhesive used for sticking can be used. By adhering the paper layer 9 to the wooden substrate 8 in this manner, the adhesive penetrates into the paper layer 9 from the wooden substrate 8 side of the paper layer 9, and when the aluminum layer 10 and the paper layer 9 are adhered to each other, Since the adhesive or the synthetic resin sheet formed inside the paper layer reaches the permeation portion of the molten resin and the single layer of the paper layer does not remain in the paper layer 9, the peel strength of the paper layer 9 is extremely high. It will be excellent.

As shown in FIG. 3, a paper layer 12 is further formed on the surface of the synthetic resin film layer 11 constituting the laminate S.
Can be attached. By forming the paper layer 12, as shown in FIG.
In the case of bonding, the adhesive penetrates into the paper layer 12, so that excellent adhesive strength can be secured.

The bonding of the paper layer 12 can be performed by heat-sealing a synthetic resin sheet or by using an adhesive in the same manner as the bonding of the aluminum layer 10 and the paper layer 9.

Further, as shown in FIG. 4, the laminate S can be attached not only on one side of the wooden substrate 8 but also on both sides of the wooden substrate 8 so that the paper layers 9 are in contact with each other. In this way, by adhering the laminate S to both sides of the wooden substrate 8, it is possible to completely block the movement of air and the movement of moisture from both the front and back sides of the moisture-proof airtight plate 4.

Further, by adhering the laminate S to both sides of the wooden substrate 8 as well as to the four corners of the wood, the movement of moisture from any direction can be completely blocked.

FIG. 5 is a sectional view taken along the line XX 'of FIG. The state in which the moisture-proof airtight plate 4 is fitted and fixed in the groove 7 formed in the vertical frames 1a and 1b is shown. Inside the groove 7, a sealing material 13 can be provided as shown in the figure. By providing the sealing material 13 inside the groove 7, even when the laminated body S is not stuck on the opening of the opening of the moisture-proof airtight plate 4, even if the four peripheral edges of the moisture-proof airtight plate are fitted in the groove, the moistureproof airtight plate 4 is fitted. The open end of the board 4 is sealed by a sealing material 13 to block absorption or release of moisture.

As the sealing material 13, silicone-based, polysulfide-based, polyurethane-based, acrylic-based,
An amorphous seal made of a synthetic resin of BR or butyl rubber type, or a fixed seal having elasticity made of foamed or unfoamed vinyl chloride, chloroprene rubber, ethylene propylene rubber or silicone rubber resin Materials can be used.

The moistureproof airtight plate 4 shown in FIG. 5 is a laminate in which the laminated body S is adhered to one side of the wood substrate 8 on the side of the heat insulating plate 5. As a result, it is impossible to reach the surface of the wooden substrate 8, and furthermore, the water that is going to enter the fitting portion with the vertical frames 1a and 1b is also blocked by the sealing material 13, so that the copper building panel body was constructed. Later, even if the humidity on the heat insulating plate 5 side rises, the movement of moisture is completely shut off between the front side and the back side of the building panel, and the humidity on the opposite side is not affected at all. It is.

FIG. 6 shows a vertical frame 1 of a building panel according to the present invention.
FIG. 2 is a sectional view showing a state in which a is fixed to a pillar 14 by nails 16 to form a true wall between pillars. In FIG. 6, reference numeral 15 denotes four peripheral edges, and 17 denotes an outer wall.
When the architectural panel body of the present invention is incorporated as a true wall, the movement of moisture between the front and back surfaces of the architectural panel body is completely shut off. By simply adhering 18, a moisture-proof and airtight performance equal to or higher than that of a conventional moisture-proof and airtight sheet can be obtained.

Further, by providing heat insulating plates on both sides of the moisture-proof and airtight plate 4 in the building panel body, the heat-insulating plates are also provided on the indoor side of the moisture-proof and airtight plate 4 in FIG.
And the same surface as the indoor side surface, and the interior side finish can be obtained only by sticking a decorative material on the surface.

Further, the construction panel body of the present invention has a method of forming a notch at a corner of a pillar and fitting and fixing the construction panel body into the notch, or a construction panel body outside the pillar. It can also be used in a method of arranging and fixing the frame materials so as to be joined together.

Further, by fixing the building panel of the present invention not only to use as a panel constituting a wall surface, but also to a floor joist or a large scale, it is possible to obtain moisture-proof and airtight performance on the floor surface. Also, by fixing the architectural panel of the present invention to the beam on the ceiling, the moisture-proof and airtight performance on the ceiling surface can be similarly obtained.

[0040]

According to the construction panel body of the present invention, the surface on which the laminate S is adhered has a high airtightness and high heat insulation construction method.
Since it has the same moisture-proof and air-tight performance as when a moisture-proof and air-tight sheet is stuck, by using this building panel body as a panel with high air-tightness and high thermal insulation method, only between the panels or at the fixed part with the structural material, Only by performing moisture-proof air-tight treatment such as filling with a moisture-proof air-tight tape or a synthetic resin film, air-tight performance can be ensured, and the construction period can be significantly shortened. Furthermore, since heat radiation is performed by the aluminum layer, the heat insulating effect is sufficiently exhibited.
