FIG. 1 is a perspective view showing one embodiment of a heat insulating panel according to the present invention, and FIGS.
FIG. 5 is a partial enlarged view of FIG.

In FIGS. 1 to 5, reference numeral 1 denotes a chip material having strength as a wall material, for example, a chip material made of OSB (Oriented Structural Board) or the like, or a surface material for a load-bearing wall made of Rawan material, and 2 denotes a heat insulating material. It is a panel body.
The heat insulation panel body 2 is composed of a vertical frame 3 made of wood, resin or concrete, an upper frame 4, a lower frame 5, a middle frame 6, and a warp preventing plate 7 made of OSB or the like, mutually fixed by a fixture 30 such as a nail. The frame 10 is assembled by fixing, and the frame 1 thus assembled is
A sheet 8 made of paper, resin, cloth, or the like, called a laminate sheet, is adhered to the inside and outside of the room 0, and the inside and outside surfaces are held down by a hot press, and the sheet 8, the frame members 3 to 6 and the warp prevention plate 7 Is formed by injecting and filling a foaming material 9 into an internal space surrounded by.

The warpage preventing plate 7 is for preventing the inward and outward warping between 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. FIG.
As shown in the figure, both ends and an intermediate portion are fitted into the concave portions 3a and 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. Mounted.

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 outer peripheral portion of the face material 1 on the indoor side. As shown in FIG.
Is composed of a base portion 11a made of hard resin such as hard vinyl chloride resin and the like which is an attachment portion to the frame members 3 to 5, and an airtight portion 11b made of soft resin such as soft vinyl chloride resin having flexible elasticity and having a fin shape. The base member 11a has a frame material 3
Mounting fittings 11c to be fitted in the grooves 13 of FIGS.
It is formed on the indoor side of the floor portion 11a . The airtight material 11 is
The base portion 11a including the fitting portion 11c and the airtight portion 11b are integrally molded by pressing together. FIG.
As shown in FIG. 5, the airtight portion 11b is
b, and is formed diagonally so that the tip is directed to the outside of the room. These airtight materials 11 and 12 are each frame material 3 ~
5 or the entire length of each side of the face material 1, and adjacent airtight materials 11, 12 at the ends of the frame materials 3 to 5 or at the corners of the face material 1 abut against each other.

FIG. 6 is a manufacturing process diagram of the present embodiment. First, as shown in the front view of FIG. 6A and the side view of FIG. Nails, tucker,
Assemble with the fixing device 30 such as a screw. 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.
3 is fitted with a fitting portion 11c for attachment of the airtight material 11. In this case, in order to prevent the displacement of the airtight material 11,
It is more preferable that the airtight material 11 is fixed to the frame members 3 to 5 by 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, in this embodiment, since the face material 1 can be attached to the frame after the foam material 9 contracts,
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, it is possible to prevent or reduce the warpage of the face material 1 and thus the warpage of the heat insulating panel body 2,
Warpage of the entire heat insulating 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 heat insulating panel can be easily mounted. If there is no warp,
1 and the exterior material 20 can be easily attached, the work of adjusting the thickness of the stud adjusting material 23 can be reduced, and the interior material can be easily attached. Needless to say, the indoor / outdoor structure of the heat insulating panel is variously changed in addition to this example.

The hermetic portion 11b of the hermetic member 11 is formed in a fin shape by using a soft resin, and the hermetic portion 11b is bent by pushing the frame portion formed by the frame members 3 to 5 of the heat insulating panel between the shafts. In addition, the elasticity of the hermetic portion 11b causes the hermetic portion 11b to adhere along the surface of the shaft assembly such as the column 16, so that hermeticity 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. If the gap is small, it is difficult to insert or turn up the heat insulating panel between the frame members if the gap is narrow, and the mass of the material increases, resulting in waste of the material. By forming the hermetic portion 11b in a fin shape as in the embodiment, the mass of the material does not increase. Further, since the heat insulating panel can be mounted without worrying about sponge turning over, the mounting workability is good.

The present invention is also applicable to a structure in which a plate-like heat insulating material is fitted as a heat insulating material provided in a frame. However, as in the present embodiment, the heat insulating material is formed by a foam material 9. By configuring, it is not necessary to incorporate solid heat insulating material into the frame, and it is not necessary to close the gap between the heat insulating material and the inner surface of the frame with caulking material, which simplifies the process. There is an advantage that it is made. Further, when the heat insulating material is configured by injecting and filling such a foam material, the frame members 3 to 5 are configured by the wooden, resin, or concrete frames.
Unlike the case where the frame members 3 to 5 are 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. Insulation process is simplified.

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.

[0020]

[0021]

Further, the heat insulating panel according to the present invention can be fitted between relatively narrow shafts, without the above-mentioned middle frame 6, or not a right-angled quadrilateral but one side inclined with respect to the other side. In some cases, the shape may be a quadrilateral or a triangle. In addition, a heat-insulated panel having a punched portion formed so that a window frame can be mounted inside the heat-insulated panel, a heat-insulated panel having a lower surface as a middle frame, such that the window frame is interposed in the middle and the window frame can be fixed,
A heat insulating panel or the like having an upper surface as 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 sheet 8, the foam material 9, the frame 1
Various modifications and additions can be made to the structure and shape of the airtight members 11 and 12 and the like.

[0024]

According to the present invention, the airtight material comprises a resin base portion and a soft resin airtight portion having a flexible elasticity, and the airtight portion is formed so as to project obliquely to the outside of the room. Since the fitting portion provided on the indoor side of the portion is fitted into the groove provided on the outer periphery of the frame and the airtight material is attached to the frame, the bending of the airtight material as in the case of pasting a conventional band-shaped airtight material. It is not necessary to pay close attention to the installation, and it is very easy to install the airtight material.Because there is no possibility that it can be bent and attached as in the case of pasting, the mounting position accuracy is improved, airtightness, Insulation can be reliably maintained.

Further, since the airtight material is composed of a resin base portion fixed to the outer periphery of the frame and a soft resin airtight portion having a flexible elasticity, compared with the conventional airtight material made of sponge, the heat insulating panel and The absorption range of the gap between the framings is widened, there is no problem of turning over or peeling, airtightness and heat insulation can be reliably maintained, and a highly reliable heat insulating panel can be provided.
Further, when the heat insulating panel is mounted between the frames, there is no fear of turning up or peeling off, and the workability of mounting the heat insulating panel is improved.
