DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel which is provided with a frame member between frames of a wooden building and is attached thereto to construct walls and roofs having excellent heat insulating properties and airtightness.

[0002]

2. Description of the Related Art In order to provide a wooden building capable of saving energy required for cooling and heating, a heat insulating panel capable of constructing a wall having excellent heat insulating properties and airtightness is provided with a frame (a pillar or a stud, a base, a trunk, a girder, etc.). It is used in a form that is embedded in the market, and its proportion is gradually increasing. As such a heat insulating panel, as shown in the view from the indoor side in FIG. 6 and the cross-sectional view in FIG. 7, the present applicant attaches a fixture such as a tucker 5 to the indoor side plate surface of the load-bearing wall face material 1. The left and right frame members 2 as the vertical frame members and the upper and lower frame members 3 and 4 as the horizontal frame members are fixed by
A wooden frame 6 for fixing the rim of the trunk is vertically set in the center, and a foam material 7 is injected into the inner space surrounded by the face material 1, the frame materials 2 to 4 and the wooden frame 6, and is filled and cured. , Japanese Patent Application No. 6-142351
And Japanese Patent Application No. Hei 6-173261.

The structural portion 8 of each of the frame members 2 to 4 covers the periphery of the foam material 7 and has an outer peripheral portion a integrally provided with the airtight portion 9 and a surface on the outdoor side and the indoor side around the foam material 7. , Respectively, and a flange d formed so as to protrude outward from the exterior b so as to be flush with the exterior, and integrally provided with the airtight portion 10.

[0004] As shown in the cross-sectional view of FIG. 8, a fin-shaped airtight portion 9 formed on each of the frame members 2 to 4 has an inner peripheral surface of a shaft assembly, that is, a left and right frame member 2. In the case of the frame material 2, it is brought into contact with the side surface of the pillar or stud 11 (in the case of the upper frame material 3, the lower surface of the girder or girth, in the case of the lower frame material 4, the upper surface of the base or girth). Fin-shaped airtight part 1
0 is the outdoor surface of the pillar or stud 11 in the case of the left and right frame members 2 (the outdoor surface of the girder or body insert in the case of the upper frame member 3, and the base or trunk in the case of the lower frame member 4). It is brought into contact with the outer surface of the plunger, and is fixed to a frame (a column or stud 11, a girder, a girth, a base, etc.) by a fixture 12 such as a nail.

[0005] As shown in the example of FIG. 8, the wooden frame 6 of the heat-insulating panel has a rim 1 on which an exterior material 13 such as siding is mounted.
4 is attached by a fixture 15 such as a nail. Further, the interior material 16 is fixed to the interior part c of the frame members 2 to 4 with a fixture 17 such as a screw on the indoor side surface of the heat insulating panel, and is covered with a finishing material 18 such as mortar or board. .

[0006]

However, in such a heat insulating panel, the foam material 7 is formed of the face material 1 and the frame materials 2 to 2.
After filling the space surrounded by 4, shrinkage of the foam material 7 (this shrinkage starts after 1 to 2 days have passed since the production of the heat insulating panel,
It will subside in about two weeks to one month. ), The foam material 7 fixed to the frame material 2 pulls the frame material 2 as shown by an arrow X in FIG. In addition, since the frame material 2 is pulled in this way and the foam material 7 is fixed to the face material 1, both ends of the face material 1 are also directly pulled by the foam material 7 due to the contraction of the foam material 7, There is a problem that the material 1 warps on both sides toward the room as shown by an arrow Y.
When such a warp occurs, not only does the appearance deteriorate, but also the dimensional accuracy of the heat insulating panel deteriorates. As can be understood from the mounting state shown in FIG. Adhesion deteriorates, and heat insulation and airtightness decrease. In the height direction of the heat-insulating panel, warping occurs such that the upper and lower sides of the heat-insulating panel are closer to the indoor side than the center. Since the face material 1 is fixed by the fixture, the vertical warpage of the heat insulating panel is considerably corrected.

In order to prevent the occurrence of warpage of the face material 1 in the heat insulating panel as described above, it is conceivable that the frame materials 2 to 4 are made of a material which is easily deformed such as rubber.
When the frame members 2 to 4 are easily deformed, as described above, the frame members 2 to 4
The deformation of No. 4 lowers the dimensional accuracy, and deteriorates the heat insulation and airtightness. Even if the frame members 2 to 4 are easily deformed, the contraction force of the foam material 7 directly acts on the face material 1, and the occurrence of some warpage of the face material 1 is inevitable.

As another means for eliminating the warpage of the face material 1, as shown in FIG. 9, a sheet 23 such as paper is applied to the face material 1 and the inner surfaces of the frame materials 2 to 4. It is conceivable that the foam material 7 is filled and hardened by the above method. However, when such a sheet 23 is provided, the foam material 7 shrinks as shown by the arrow X, so that the face material 1 and the frame materials 2 to 4 A gap 24 is opened in the inner surface, which deteriorates the heat insulation and airtightness. In addition, if a heat insulating panel is attached to the frame in this state, in a cold season, dew condensation inside the wall occurs due to a temperature difference between the inside and outside of the wall, and the durability of the building is reduced. Adversely affect

In view of the above problems, the present invention can suppress the occurrence of warpage of the surface material of the heat insulating panel, thereby improving the dimensional accuracy, thereby improving and stabilizing the quality such as heat insulation and airtightness. An object of the present invention is to provide a heat insulating panel having a structure.

[0010]

The heat insulation panel of the present invention comprises:
In order to achieve the above object, vertical and horizontal frame members are fixed to the load-bearing wall surface material, and on the indoor side between the left and right frame materials fixed to the surface material,
A regulating member for preventing the dimension between the frame members from shrinking is erected at an interval between the regulating member and the face member, and a foam material is filled in an inner space surrounded by the frame member and the face member. And cured.

[0011]

According to the heat insulating panel of the present invention, a regulating member is provided between the left and right frame members to prevent the contraction of the dimension between the two frame members.
After the foam material is filled and cured, even if the foam material tries to shrink, the shrinkage between the left and right frame materials is prevented by the regulating member, so the foam material is fixed around the left and right frame materials and face materials. Is suppressed, and thereby, the occurrence of warpage of the face material is suppressed.

[0012]

FIG. 1 is a view of an embodiment of a heat insulating panel according to the present invention as viewed from the indoor side, FIG. 2 is a cross sectional view of the present embodiment, and FIG. 3 is a sectional view taken along line EE of FIG. 1 to 3,
6 to 9 denote members that perform the same functions. As the face material 1, a structural plywood or an OSB (oriented strand board) having strength as a wall material can be used. The frame members 2 to 4 are frame members fixed to the left and right sides of the indoor side plate surface of the face member 1 by a fixing tool such as a tucker 5 or an adhesive. The structural part 8 is made of a hard resin, and the airtight parts 9 and 10 made of a soft resin such as a soft vinyl chloride resin are integrally molded with the structural part 8 by co-pressing. In addition, as the material of the hard resin structural portion 8 of the frame members 2 to 4, besides the above examples, polyethylene, polypropylene, polystyrene, ABS resin, polycarbonate, polyamide, polyphenylene oxide, and the like can be used. Resin airtight parts 9, 10
As the material of, in addition to the above examples, thermoplastic elastomer,
Plastic polyvinyl alcohol or the like can be used, but resins other than these may be used as long as they satisfy the functions of the structural portion 8 or the airtight portions 9 and 10, respectively.

When the structure 8 and the hermetic parts 9 and 10 are integrated as in this embodiment, the means for integration may be any as long as a process suitable for mass production is taken.
Airtight parts 9 and 1 made separately from the fitting part provided in the structural part 8
0 may be integrated in the process of fitting or inserting the component members. Also, the flanges d of the frame members 2 to 4,
A portion that protrudes outward from the outer peripheral portion a of the frame material of the face material 1 in a flange shape may be eliminated, and a heat-insulating panel structure may be entirely fitted into the frame. Further, the airtight portions 9 and 10 may be separate members made of sponge or resin and adhered to the frame members 2 and 3 with a double-sided tape or the like.

Reference numeral 25 denotes a regulating member provided according to the present invention. The regulating member 25 of this embodiment is made of the same material as the face material 1 and has a length equal to the interval between the inner surfaces of the left and right frame members 2 and 2. It was prepared by cutting into pieces. As the regulating member 25,
In addition, a plate material such as wood, resin, metal, or the like, or a fiber-reinforced molded body, which is different from the face material, can be used. However, when a material different from the face material 1 is used as the regulating member 25, it is necessary to pay attention to the selection of the structure and the material because the regulating member 25 and the face material 1 have different coefficients of linear expansion.

The heat insulating panel of this embodiment has a frame material 2
4 and the wooden frame 6 are fixed, and then the concave portion 6a provided in the wooden frame 6 is formed.
Fixing members 2 such as nails and screws
6 and fix both ends of the regulating member 25 to the inner surface of the frame member 2 with a fixture 27 such as a tucker. Thereby, the regulating member 25 is installed on the indoor side between the left and right frame members 2 and 2 with a space between the regulating member 25 and the surface member 1. Thereafter, a release paper 28 is applied to the indoor side opening surface surrounded by the face material 1 and the frame materials 2 to 4, and the surroundings of the frame materials 2 to 4 and the release paper 28 are held down by a mold (not shown). It is manufactured by injecting and hardening the foam material 7 into the internal space in a flowing state. The foam material 7 is made up of the surrounding members, that is, the face material 1 and the frame material 2.
~ 4, hardened in a state of being bonded to the wooden frame 6 and the release paper 28.

In the present invention, since the regulating member 25 is provided between the left and right frame members 2 and 2 to prevent the dimension between the two frame members 2 and 2 from shrinking, after the foam material 7 is filled and cured. Even if the foaming material 7 tries to shrink, the contraction between the left and right frame members 2 and 2 is prevented by the restricting member 25, so that the left and right frame members 2 and
The shrinkage between the two is prevented, thereby preventing the shrinkage of the foam material whose periphery is fixed to the frame members 2 to 4 and the face material 1 and the regulating member 25, thereby suppressing the warpage of the face material 1. Is done. As a specific example, in the case where the width of the face material 1 is 905 mm, the height is 2200 mm, and the regulating member 25 is not provided, the warp in the width direction (lateral direction) of the heat insulating panel occurs about 6 mm. By providing the regulating member 25, the diameter was reduced to about 0 to 1.7 mm. In addition to the warpage in the width direction as well as the warp in the height direction, the warpage of about 7 mm without the regulating member 25 may be reduced to about half. confirmed. Thus, the reason why the warp in the height direction of the heat insulating panel can also be reduced is that the shrinkage of the foam material 7 is suppressed by the regulating member 25 as a whole.

By suppressing the warpage of the face material 1 as described above, it is possible to prevent the appearance and the commercial value from being reduced due to the warpage, and to improve the dimensional accuracy of the heat insulating panel as a product. Thermal insulation in the installed state,
The quality such as airtightness is improved and stabilized. Further, since the regulating member 25 is provided on the indoor side of the frame member 2 and has an interval between the face material 1 and the regulating member 25, the regulating member 25 is filled with the foam material 7 when filling the foam material 7. Not hinder the flow of
The number of steps for filling the foam material 7 is not increased.

If the hermetically sealed portions 9 and 10 are integrally formed of a soft resin by extrusion molding of the structural portion 8 and the resin, as shown in the illustrated example, the frame members 2 to 4 are several times smaller than wood. Since it can be formed thin with a thickness of the order, it is excellent in heat insulation and can be reduced in weight as compared with a conventional one using a wooden frame.
Further, as in the present embodiment, the structure in which the flange portion d is provided and the hermetic portion 10 is provided in the flange portion d makes it possible that the close contact between the inner peripheral surface of the shaft assembly and the hermetic portion 9 is not perfect. Even if the heat insulating panel is attached, the flange 12 is fixed to the frame by the fixture 12, and the airtight portion 10 is sandwiched between the face material 1 and the frame, thereby ensuring airtightness. Cheap.

The foaming material 7 does not require an operation of incorporating a foaming material as a molding material, as compared with a configuration in which a plate material made of a foaming material molded in advance is surrounded by frames 2 to 4. There is no need to close the gap between the inner member and the inner surface of the frame member with a caulking material, so that there is an advantage that the process is simplified.

The heat insulation panel according to the present invention is shown in FIG.
As shown in (A), as a member to be fitted between relatively narrow shaft sets, a member without the wooden frame 6, a quadrilateral in which one side is inclined with respect to the other side instead of a right quadrangle, or It may be configured in a triangle. Further, as shown in FIG. 4 (B), a punched portion 19 is formed so that a window frame can be attached inside, or as shown in FIG. 4 (C), a window frame 20 is interposed in the middle. In order to fix the window frame 20, a heat insulating panel 21 having a wooden frame 6A on the lower surface, a heat insulating panel 22 having a wooden frame 6B on the upper surface, etc.
It can be configured by replacing A and 6B. In any case, the restricting member 25 is provided at a location where a reduction in the size between the left and right frame members 2 and 2 becomes a problem.

FIG. 5A is a view of a heat insulation panel according to another embodiment of the present invention as viewed from the indoor side, and FIG. 5B is an enlarged sectional view taken along line FF of FIG. The upper and lower horizontal frame members 31 and 32 are manufactured and fixed to the face material 1 by the fixing member 33, and the respective frame members 30 to 32 are fixed by the fixing member 34. Is fitted in the concave portion 6a of the central wooden frame 6, and both ends are fitted in the concave portions 30a of the left and right frame members 30 and fixed by fixtures 35 and 36, respectively, and the foam material 7 is filled into the internal space and cured. It was made. Even in the case of such a heat insulating panel made of a wooden frame, the above-described effects of the present invention can be exerted.

The present invention can also be used as a heat insulating panel for a roof. In the present invention, various changes and additions can be made to the structure and shape of each part of the face material 1, the frame materials 2 to 4, 30 to 32, and the regulating member 25.

[0023]

According to the first aspect of the present invention, since the regulating member is provided between the left and right frame members to prevent the dimension between the two frame members from shrinking, after the foam material is filled and cured, the foam material is removed. Even if an attempt is made to contract, the restricting member prevents the contraction between the left and right frame members, so that the contraction between the left and right frame members is prevented, thereby suppressing the warpage of the face material. This prevents the appearance and commercial value of the heat insulating panel from being reduced. In addition, the dimensional accuracy is improved, and the quality such as heat insulation and airtightness is improved and stabilized. Further, since the regulating member is provided on the indoor side of the frame material and has a space between the face material and the regulating member, the regulating member does not hinder the flow of the foam material when filling the foam material, and the There is no increase in the number of material filling steps.
