DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing embodiments of the present invention,
The configuration will be described with reference to FIGS. Figure 1
Is a perspective view showing an example of a heat insulating panel , FIGS. 2, 3, and 4 are cross-sectional views taken along lines EE, FF, and GG of FIG. 1, and FIG. 5 is a partially enlarged view of FIG.

1 to 5, reference numeral 1 denotes a chip material having strength as a wall material, for example, made of OSB (Oriented Structural Board) or the like, or a surface material for a load-bearing wall made of Rawan or veneer. Is a heat insulating panel body. The heat insulating panel body 2 includes a vertical frame 3, an upper frame 4, a lower frame 5, and a middle frame 6 made of wood , resin or concrete.
And a warp prevention plate 7 made of OSB or the like,
The frame 10 is fixed to each other at 0 to form a frame 10, and a sheet 8 made of paper, resin, cloth, or the like, called a laminate sheet, is attached to the indoor side and the outdoor side of the frame 10 thus assembled. It is constituted by holding down by a hot press, injecting and filling a foaming material 9 into an internal space surrounded by the sheet 8, the frame members 3 to 6 and the warpage preventing plate 7, and curing.

The warpage preventing plate 7 prevents the warping and shrinkage of the vertical frames 3 and 3 in and out of the vertical frames 3 and 3 at the time of the foaming pressure at the time of filling the foam material 9 and the subsequent shrinkage. As shown in FIG. 3, both ends and an intermediate portion are fitted into concave portions 3a, 6a provided on the indoor side and the outdoor side of the vertical frame 3 and the middle frame 6 and fixed by a fixing tool 30 such as a nail, a tucker or a screw. It is attached by doing.

Reference numeral 11 denotes an airtight material attached to the outer peripheral surfaces of the frame members 3 to 5, and reference numeral 12 denotes an airtight material attached to the indoor surface of the outer peripheral portion of the face material 1. As shown in FIG.
Is composed of a base portion 11a made of a hard resin such as a hard vinyl chloride resin, which serves as an attachment portion to the frame members 3 to 5, and a hermetic portion 11b made of a soft resin such as a flexible vinyl chloride resin having a fin shape. And the base member 11a has frame members 3 to
5 has a mounting leg 11c fitted into the groove 13. The airtight material 11 is made up of a base portion 11a including legs 11c and an airtight portion 11a.
b is integrally formed by co-pressing.

[0010] These airtight materials 11 and 12 correspond to the respective frame members 3 to 5.
Alternatively, the airtight members 11 and 12 which are provided over the entire length of each side of the face material 1 and which are adjacent to each other at the ends of the frame materials 3 to 5 or the corners of the face material 1 are abutted with each other.

FIG. 6 is a manufacturing process diagram of the heat insulating panel . First, as shown in the front view of FIG. 6A and the side view of FIG. Assemble with fixtures 30 such as nails, tuckers and screws. Grooves 13 are previously formed on the outer periphery of the frame members 3 to 5 before assembling.

Next, FIG. 6C is a front view and FIG.
As shown in the side view, double-sided tape 14 is applied to the indoor and outdoor surfaces of the upper, lower, left and right frame members 3-5. By fixing the peripheral portion of the sheet 8 to these double-sided tapes 14, the frame 10
The sheet 8 is stuck on the indoor and outdoor surfaces of. The hollow body thus configured is fixed by hot pressing, and the frame material 3
6, a foaming material is injected and filled into the internal space surrounded by the warpage prevention plate 7 and the sheet 8 and cured. In this case, the warpage prevention plate 7 prevents the middle portion of the vertical frame 3 from warping outward due to the foaming pressure, and also prevents the middle portion of the vertical frame 3 from warping inward due to shrinkage of the foam material. The middle frame 6 prevents the upper and lower frames 4 and 5 from warping in the vertical direction due to the foaming pressure and shrinkage.

Next, as shown in the front view of FIG. 6 (E), the grooves 1 previously provided on the indoor and exterior surfaces of the upper, lower, left and right frames 3-5.
The fitting leg 11c of the airtight material 11 is fitted and attached to 3. In this case, in order to prevent the displacement of the airtight material 11, it is more preferable to fix the airtight material 11 to the frame materials 3 to 5 with a tucker 15 (see FIG. 6 (I)) or the like at intervals.

Next, as shown in the view from the outside in FIG. 6F and the side view in FIG. 6G, the contraction of the foam material 9 of the heat insulating panel body 2 manufactured as described above is completed. Then, the fixtures 31 such as nails, tuckers and screws penetrating the face material 1 are fixed to the frame members 3 to 6 of the heat insulation panel body 2 by driving. Thereafter, as shown in FIG. 6H, the airtight material 12 is attached to the outer peripheral portion of the face material 1.

As described above, since the face material 1 can be attached to the frame after the foam material 9 shrinks, warpage of the face material 1 or warpage of the heat insulating panel body 2 due to shrinkage of the foam material 9 can be prevented. The relative displacement between the heat insulating panel body 2 and the face material 1 caused by the expansion of the face material 1 due to the improvement of the moisture content of the face material 1 is caused by the relative displacement between the face material 1 or the frame materials 3 to 6 and the fixture 31 such as a nail. It can be absorbed by the compression deformation at the joint portion and the elastic deformation of the fixture 31, and as a result, the face material 1 warps and thus the heat insulation panel body 2
Warpage can be prevented or reduced, and warpage of the entire heat insulation panel can be prevented or reduced.

As shown in FIGS. 2 to 4, the heat insulating panel includes a fin-shaped airtight portion 11 b of the airtight material 11, and an inner peripheral surface of the shaft assembly, that is, a column (or stud) 16 in the case of the vertical frame 3. (In the case of the upper frame 4, the lower surface of the girder or girth 17, in the case of the lower frame 5, the base or the upper surface of the girth 18). Is brought into contact with the outdoor surface of the pillar 16 (the outdoor surface of the girder or the bobbin 17 in the case of the upper frame 4, the base or the outdoor surface of the bobbin 18 in the case of the lower frame 5), Are fixed to the shaft set. In addition, the body edge 21 for attaching the exterior material 20 such as siding is attached to the vertical frame 3 and the middle frame 6 of the heat insulating panel by a fixing tool 33 such as a nail. Further, a stud adjusting member 23 is attached to a surface on the indoor side of the middle frame 6 of the heat insulating panel with a fixture 34 such as a nail, and the pillar 16 and the like, a shaft assembly and the stud adjusting member 23 are finished with a finishing material 24 such as a board. cover.

When such a heat insulating panel is mounted, if the heat insulating panel is not warped, it is not necessary to hold the heat insulating panel to correct the warp, and the mounting of the heat insulating panel becomes easy. If there is no warp, the attachment of the trunk edge 21 and the exterior material 20 is facilitated, the work of adjusting the thickness of the stud adjustment material 23 is reduced, and the attachment of the interior material is also facilitated. Needless to say, the indoor / outdoor structure of the heat insulating panel is variously changed in addition to this example.

Further, as described above, if the airtight portion 11b of the airtight material 11 is formed into a fin shape by using a soft resin, the frame portion formed by the frame members 3 to 5 of the heat insulating panel is pushed between the shafts. The airtight portion 11b is bent, and the elasticity of the airtight portion 11b causes the airtight portion 11b to closely adhere along the surface of the shaft set such as the column 16, so that the airtightness and heat insulation are ensured. In addition, as compared with the case where the sponge follows the size of the gap between the heat insulating panel and the frame by expansion and contraction in the thickness direction of the sponge, the size of the gap is reduced by the bending of the airtight portion 11b having flexible elasticity. , It is possible to cope with a wide range of the size of the gap, and airtightness and heat insulation can be secured. Further, when a gap of, for example, a maximum of about 15 mm is formed between the frame members 3 to 5 and the frame due to a mounting error of the frame members 3 to 5 and a construction error of the frame, a sponge having a thickness of about 15 mm is framed. when stuck around a timber 3 to 5, wherein the gap is over resulting in insertion between framing insulation panels difficult or curling when narrow, mass of the material is increased, while waste of material occurs, the Airtight part 11 as in the example
By forming b in a fin shape, the mass of the material does not increase. Further, since the heat insulating panel can be mounted without worrying about the sponge being turned up, the mounting workability is good.

Further, since the heat insulating material is constituted by the foam material 9, the work of assembling the solid heat insulating material into the frame becomes unnecessary, and the gap between the heat insulating material and the inner surface of the frame material is reduced by the caulking material. This eliminates the need for the work of closing, so that there is an advantage that the process is simplified. When a heat insulating material is formed by injecting and filling such a foam material, the frame materials 3 to 5 are formed by the wooden, resin, or concrete frames.
Unlike the case where the resin material 5 is formed of a resin molded body, it is not necessary to apply a jig for receiving foaming pressure to the frame members 3 to 5, and the foam material can be solidified. Becomes easier.

The material of the base portion 11a of the airtight material 11 may be polyethylene, polypropylene, polystyrene, ABS resin, polycarbonate, polyamide, polyphenylene oxide or the like in addition to the above examples. As a material of the hermetic portion (hermetic material) 11b, in addition to the above examples, a thermoplastic elastomer, a plastic polyvinyl alcohol, or the like can be used. A resin may be used. Further, as a means for integrating the base portion and the airtight portion, another method may be used as long as a process suitable for mass production is taken.

FIG. 7 is a cross sectional view showing an embodiment of the present invention.
FIG. 8 is a sectional view corresponding to GG of FIG. 1 of the embodiment. Also in this embodiment, sheets 8 are provided on both sides of the frame members 3 to 5 inside and outside the room.
After the foam material 9 is filled and cured, the foam material 9 shrinks, and then the face material 1 is fixed by the fixture 31. In this example, the airtight material 35 attached to the indoor side is a base portion 35a made of a hard resin as described above, as in the above embodiment.
And the hermetic portion 35b made of a soft resin are integrally molded by pressing together. The airtight material 36 attached to the outer peripheral portion of the face material 1 also includes a base portion 35a and an airtight portion 35, respectively.
It comprises a base portion 36a made of the same material as b and a fin-shaped airtight portion 36b. In the present embodiment, in order to facilitate attachment of these airtight materials 35, 36, the base portion 3
A structure in which the cross-sectional shapes of 5a and 36a are formed in a U-shaped cross- section to be applied along the indoor corners of the frame members 3 to 5 and fitted to the outer peripheral portions of the frame members 3 to 5 or the surface material 1, respectively. And In this embodiment, the indoor sheet 8 is attached after the airtight material 35 is attached to the frame members 3 to 5.

According to this embodiment, the frame members 3 to 3 of the airtight material 35
5 or the airtight material 36 on the outer surface of the face material 1 is formed in a U-shaped base portion 35a, 36a.
By being fitted into the outer peripheral portions of the frame members 3 to 5 and the face material 1, the attachment becomes very easy as compared with pasting as in the past, and each airtight material 35,
36 is positioned by being fitted to the outer peripheral portions of the frame members 3 to 5 and the face material 1, so that it is mounted with high positioning accuracy, does not have a displacement as in the case of pasting, and has airtightness.
Heat insulation is ensured.

Further, as in the present embodiment, the fixing strength of the hermetic material 35 is improved by fixing the portion 35c that contacts the inner surfaces of the frame members 3 to 5 to the heat insulating material 7 by using the adhesive force of the foam material. Go up. In addition, by simply setting the airtight material 35 in the frame members 3 to 5 and filling the foam material without necessarily using an adhesive or a fixing tool, the formation of the foam material 9 which is a heat insulating material and the fixing of the airtight material 35 are performed. Can be performed at the same time, so that the airtight material 35 can be easily attached.
No temporary fixing means is required, facilitating manufacture and assembly,
Simplification can be achieved. In addition, the mounting strength of the airtight member 35 can be increased in combination with the fact that the base portion 35a of the airtight member 35 is fitted to the frame members 3 to 5.

Further, as in the present embodiment, if the airtight members 35 and 36 are formed by separate members with respect to the shaft set such as the pillar 16 or the like, the heat insulating panels for ceiling, floor or wall can be formed. In some cases, at least one of the hermetic member 35 attached to the frame members 3 to 5 and the hermetic member 36 attached to the outer peripheral portion of the face member 1 may be used in common, and a common manufacturing line and common parts management can be achieved. Can be achieved.

The structure of the airtight material can be variously changed in addition to the above embodiments. For example, as shown in FIG. 9 , by providing a fin-shaped airtight piece 36 c in the longitudinal direction on the inner surface of the base portion 36 a of the airtight material 36 attached to the outer peripheral portion of the surface material 1, Air can be prevented from passing through the gap, and the airtightness can be improved.

On the other hand, as shown in FIG. 9 , the base portion 35a of the airtight material 37 attached to the frame members 3 to 5 is provided with a portion 37c for covering the indoor side surface of the foam material 9 so that the foam material 9 is provided.
The airtight material 35 can be fixed to the frame members 3 to 5 by utilizing the adhesive force of the above. Further, in the case where the indoor side opening surface of the framework including the frame members 3 to 5 and the middle frame 6 and the warp prevention plate 7 is closed, and the sheet 8 is applied to the airtight material 37 and the foam material is filled, the warp prevention plate 7 is airtight. The warp preventing plate 7 can be foamed while being pressed by the member 37, and the end of the warp preventing plate 7 can be covered with the airtight material 37. It is only necessary to abut the end of the frame 7 on the inner surface of the frame member 2 as shown in the figure, and there is an advantage that it is not necessary to provide a concave portion for fixing the end of the warpage prevention plate 7 in the frame member.

The airtight material 50 shown in FIG.

As shown in FIG. 11 (B), even if the airtight material 52 has a hollow airtight portion 52b made of a soft resin formed by co-pressing with the base portion 52a, a manufacturing error and a construction error may occur. Can be secured. This hollow shape can also be applied to the airtight portion of the airtight material 36.

In the present invention, there may be a case where the above-mentioned middle frame 6 is not provided, a quadrangle in which one side is inclined with respect to the other side, or a triangle instead of a right quadrangle. In addition, a punched portion is formed so that a window frame can be attached inside the heat insulating panel, a heat insulating panel having a lower surface as a middle frame, and an upper surface having a lower surface so that the window frame is interposed and the window frame can be fixed. A heat insulating panel or the like having a middle frame can also be configured by replacing some frame materials with a middle frame.

In addition, in the present invention, the face material 1, the heat insulating panel main body 2, the frame materials 3 to 5, the foam material 9, and the airtight materials 35 to 3
Various changes and additions can be made to the structures and shapes of 9 , 50, 51 , 52, and the like.
