BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel for constructing a wall having excellent heat insulating properties and airtightness by installing a frame member between frame members of a wooden building and attaching the frame member.

[0002]

2. Description of the Related Art In order to provide a wooden building capable of saving energy required for heating and cooling, a heat insulating panel capable of constructing a wall having excellent heat insulating properties and airtightness is a frame (column, base, barrel, girder, etc.).
It is used in the form that is incorporated between the two, and the ratio is gradually increasing. As shown in FIG. 8, a conventional heat insulation panel has a wooden frame 31 fixed to one surface of a face material 30, a heat insulating material 32 is fitted into the wooden frame 31, and an outer periphery of the heat insulating material 32 and an inner wall of the wooden frame 31. Fill the gap between them with caulking material 33,
The belt-like airtight members 34 and 35 having elasticity are attached to the outer periphery of the plate and the plate surface of the face member 30, respectively. In this heat insulating panel, the wooden frame 31 is fitted into the frame, and the airtight material 34 around the wooden frame 31 is brought into contact with the inner peripheral surface of the frame (the side surface of the pillar, the upper surface of the base, the lower surface of the body, etc.). Then, the airtight material 35 attached to the face material 30 is brought into contact with the outdoor side or the indoor side surface of the shaft assembly and fixed by a nail or the like to be attached.

However, the conventional heat insulating panel described above has the face material 3
It is configured by fixing the wooden frame 31 to 0, and the wooden frame 3
In the case of 1, the dimensional accuracy is difficult to obtain due to the cutting process, which causes a variation in the gap between the wooden frame 31 and the frame, resulting in deterioration of airtightness and heat insulation. there were. Further, the wooden frame 31 is not suitable for mass production and is expensive.

In view of these problems, the present applicant has proposed a heat insulation panel which has improved dimensional accuracy, which stabilizes airtightness, heat insulation, and other qualities and which is suitable for mass production and achieves cost reduction. As shown in the perspective view of FIG. 9, the left and right frame members 2 as vertical frame members and the upper and lower frame members 3 as horizontal frame members are fixed to the indoor side plate surface of the load bearing wall surface member 1 by a fixture such as a tacker. 4 is fixed, a wooden frame 6 for vertically fixing the furring strip is erected vertically in the central portion, and the 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 cured. To develop
It is proposed as Japanese Patent Application No. 6-142351.

[0005]

However, in the heat insulation panel shown in FIG. 8, the foam material 7 is used as the face material 1 and the frame material 2.
After being filled in the space surrounded by ~ 4, the foam material 7 shrinks (this shrinkage starts after 1 to 2 days have passed after the heat insulating panel is manufactured and is almost stopped in about 2 weeks to January). Since the foam material 7 fixed to the materials 2 to 4 pulls the frame materials 2 to 4, the frame materials 2 to 4 are deformed. In addition, in this way, the frame material 2
4 is pulled, and since the foam material 7 is fixed to the face material 1, the 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, whereby the face material 1 or the frame material 2 Both sides of No. 4 warp toward the indoor side (the warp in the width direction of the frame member is Δx and the warp in the height direction is Δy, which are exaggeratedly represented for the sake of description). When such warpage occurs, not only the appearance is deteriorated, but also the dimensional accuracy of the heat insulating panel is deteriorated, and the heat insulating property and airtightness in the attached state are deteriorated.

In view of the above problems, the present invention can suppress the warpage of the face material of the heat insulating panel, thereby improving the dimensional accuracy, thereby improving and stabilizing the quality such as heat insulating property and airtightness. Moreover, it is an object of the present invention to provide an insulating panel that can be manufactured at low cost.

[0007]

The heat insulating panel of the present invention comprises:
A vertical and horizontal frame material made of synthetic resin for foam material filling on the indoor side surface of the bearing wall surface material made of the Oriented Structural Board. By fixing it so as to be narrow, the periphery of the face material is used as a flange for mounting the panel, and vertically long wood members are interposed between the upper and lower frame members fixed to the face material, and the left and right sides fixed to the face material are fixed. Between the frame members, a horizontally-long regulating member for preventing the shrinkage of the dimension between the frame members to prevent the heat insulating panel from warping in the width direction is interposed, and the indoor side opening surrounded by the vertical and horizontal frame members. The surface is covered with a sheet, and an internal space surrounded by the frame material, the surface material and the sheet is filled with a foam material and cured. Here, the Oriented Structural Board (hereinafter referred to as OSB) is a panel also referred to as the Oriented Strand Board. This panel is a small-diameter tree that is processed into a wafer shape, and is water and heat resistant. It is a hot-pressed resin. In the present invention, preferably, a waste material of the OSB raw material cut out from the face material is used as the regulating member.

[0008]

In the heat insulating panel of the present invention, since the regulating member is interposed between the left and right frame members, even if the foam material shrinks after the foam material is filled in the frame and hardened, the left and right members are controlled by the regulating member. Since the shrinkage between the frame members is prevented, the shrinkage of the foam material that is fixed to the left and right frame members and the face material is suppressed, which suppresses the warpage of the face material in the width direction. It In addition, by suppressing the occurrence of warpage in the width direction of the face material and frame material, the warpage in the height direction is also reduced to some extent. It is suppressed by the wood member and is corrected by fixing the collar portion on the side portion of the face material to the column with a fixture.

As shown in FIG. 5 (A), the structural portion 8 of each of the frame members 2 to 4 covers the periphery of the foam material 7 and the outer peripheral portion a integrally provided with the airtight portion 9 and the foam material 7. The outdoor part b and the indoor part c respectively covering the outdoor side and the indoor side surface around the, and the outwardly protruding from the outdoor part b so as to be flush with the outdoor part b. It is composed of a collar portion d provided integrally.

As the material of the hard resin structure portion 8 of the frame members 2 to 4, polyethylene, polypropylene, polystyrene, ABS resin, polycarbonate, polyamide, polyphenylene oxide, etc. can be used in addition to the above examples. Further, as the material of the airtight portions 9 and 10 made of the soft resin, thermoplastic elastomer, plastic polyvinyl alcohol or the like can be used in addition to the above-mentioned examples, but those satisfying the functions of the structural portion 8 or the airtight portions 9 and 10, respectively. If so, a resin other than these may be used.

When the structural portion 8 and the airtight portions 9 and 10 are integrated as in the present embodiment, the means for integration may be any means that can take steps suitable for mass production.
Airtight parts 9 and 1 produced separately from the fitting part provided in the structure part 8.
They may be integrated in the process of fitting or inserting the 0 constituent members. Further, the airtight portions 9 and 10 may be separate members made of sponge or resin and adhered to the frame members 2 to 4 with a double-sided tape or the like.

As shown in FIGS. 1 to 4, the foam material filling portion surrounded by the outer peripheral portion a of the frame members 2 to 4 is fixed so as to be narrower than the face material 1, whereby the face material 1 of the face material 1 is fixed. Left and right flanges 1a for mounting the panel and upper and lower flanges 1b, 1c are formed around the periphery.

Between the upper frame 3 and the lower frame 4, there is provided a vertically long wooden member 6 for preventing vertical warp, and the upper and lower ends of the vertical wooden member 6 are the upper and lower frames 3, 4 respectively.
It is provided in contact with the inner surface of the. Reference numeral 25 is a regulating member provided by the present invention, and the regulating member 25 is made of OSB, and the regulating member 25 is manufactured by cutting into a length equal to the distance between the inner surfaces of the left and right frame members 2, 2. Yes, Figure 3, Figure 4
As shown in FIG.
5 is attached by fitting the central portion of 5 with fixtures 26 such as nails and screws, and fixing both ends of the regulating member 25 against the inner surface of the frame member 2 with fixtures 27 such as tuckers.

The heat insulating panel of this embodiment is manufactured by fixing the frame members 2 to 4, the wooden member 6 and the regulating member 25 to the face material 1, and then, on the indoor side surrounded by the face material 1 and the frame members 2 to 4. Sheet 2 made of coated paper called laminated paper on the opening side
8 so as not to leak liquid, and press the periphery of the frame members 2 to 4 and the sheet 28 with a mold (not shown), and
It is produced by injecting into the internal space in a fluidized state and curing. The foam material 7 is hardened in a state of being adhered to surrounding members, that is, the face material 1, the frame materials 2 to 4, the wood member 6, the regulating member 25, and the sheet 28. As the sheet 28, plywood or an aluminum foil laminated with paper may be used instead of paper. Here, the OSB cuts out a face material from a raw material having a predetermined size, and cuts out and uses a remaining waste material as a restriction member, so that the material cost of the restriction member 25 becomes unnecessary. The regulating member 25 may have a laminated structure in which the wafer of each layer is oriented in any direction, but as shown in FIG. 5B, the wafer of the surface layer e is indicated by an arrow f. Is oriented in the longitudinal direction of the regulating member 25, and the inner layer g has an arrow h
As shown in FIG. 5, by cutting out the raw material such that the wafer is oriented in a direction perpendicular to the longitudinal direction or in an arbitrary direction, a regulation member having a high bending strength can be obtained.

When this heat insulating panel is attached to a building, as shown in the cross-sectional views of FIGS. 1 and 6, the inner peripheral surface of the frame, that is, the pillars (including studs) in the case of the vertical frame 2 1
1 side surface (in the case of the upper frame 3, the lower surface of the upper horizontal member 40 made of a girder or a girder, and in the case of the lower frame 4, the upper surface of the lower horizontal member 41 made of a base or a girder), Airtight part 10
Is the surface of the pillar 11 on the outdoor side in the case of the vertical frame 2 (the surface of the upper horizontal member 40 on the outdoor side in the case of the upper frame 3, and the outdoor side surface of the lower horizontal member 41 in the case of the lower frame 4). To the left and right sides of the face material 1
a is fixed to the pillar 11 by a plurality of fixing tools 12 such as nails, and the upper and lower flange portions 1b, 1c are also fixed to the upper horizontal member 40 and the lower horizontal member 41 by a plurality of fixing tools 12, respectively.

In the example of FIG. 6, a furring strip 14 for mounting an exterior material 13 such as siding is attached to the wooden member 6 of the heat insulating panel 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 by a fixture 17 such as a screw on the surface of the heat insulation panel on the interior side,
It is covered with a finishing material 18 such as mortar or board.

In the present invention, as described above, since the regulating member 25 is provided between the left and right frame members 2 and 2 to prevent the dimension of the frame members 2 and 2 from shrinking, the foam material 7 is filled. Then, even if the foam material 7 shrinks after being cured, as shown by an arrow F in FIG.
To prevent the foam material 7 fixed to the frame material 2 from contracting, and as a result, the face material 1 as shown by the two-dot chain line in FIG.
The occurrence of warpage in the width direction of the frame members 2 to 4 is suppressed. 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, warpage in the width direction (lateral direction) of the heat insulating panel is generated by about 6 mm, By providing the regulating member 25, it is reduced to about 0 to 1.7 mm. Further, not only such a warp in the width direction but also a warp in the height direction, which was about 7 mm in the case without the regulating member 25, can be reduced to about half. confirmed. Thus, the reason why the warp in the height direction of the heat insulating panel can be reduced is that the shrinkage of the foam material 7 is suppressed by the regulating member 25 as a whole.

Further, a face material 1 as shown by a chain double-dashed line in FIG.
The warp in the height direction of the frame members 2 to 4 is also reduced to some extent by suppressing the occurrence of the warp in the width direction of the face material 1 and the frame member 2 by the restricting member 25, and also the wooden member. In addition to being suppressed by 6, the left and right flanges 1a of the face material 1 are fixed to the pillar 11 by the fixture 12, and the arrow F
It is corrected by being pressed by the fixture 12 as shown by.

By suppressing the warpage of the face material 1 and the frame members 2 to 4 in this manner, it is possible to prevent the appearance and the commercial value from being deteriorated due to the occurrence of the warp when the synthetic resin is used as the frame members 2 to 4. In addition, since the dimensional accuracy of the heat insulating panel as a product is improved, the quality such as heat insulating property and airtightness in the state of being attached to the frame is improved and stabilized.

If the airtight portions 9 and 10 are made of a soft resin and the structural portion 8 and the resin are integrally formed by extrusion molding as in the illustrated example, the frame members 2 to 4 are a few times smaller than wood. Since it can be formed to a small thickness and is thin, it is superior in terms of heat insulation and can be made lighter than the one using a conventional wooden frame.
Further, due to the structure in which the collar portion d is provided and the airtight portion 10 is provided in the collar portion d as in the present embodiment, the adhesion between the inner peripheral surface of the frame and the airtight portion 9 is not perfect. Even if the heat insulating panel is attached, the collar 12 is fixed to the frame by the fixture 12 and the airtight part 10 is sandwiched between the face material 1 and the frame, so that the airtightness is secured. Cheap.

Further, the foam material 7 does not require the work of incorporating the foam material as a molding material as compared with the structure in which a plate material made of a foam material which is previously molded is surrounded by the frame members 2 to 4, and the foam material 7 Since there is no need to work the gap between the inner surface of the frame and the inner surface of the frame material with a caulking material, there is an advantage that the process is simplified.

According to this embodiment, the face material 1 and the regulating member 25 are
Since the space is formed between the control member 25 and the frame member 2 to 4, the regulating member 25 does not become an obstacle when the resin is filled between the face member 1 and the frame members 2 to 4, and the number of steps of the resin filling step can be reduced. There are advantages. Further, by using the same material as the face material 1 as the regulating member 25, the number of raw materials can be reduced.

The heat insulating panel according to the present invention is shown in FIG.
As shown in (A), as a member to be fitted between relatively narrow shafts, a member without the wooden member 6, a quadrangle whose one side is inclined with respect to the other side instead of a right-angled quadrangle, or It may be configured in a triangle. Further, as shown in FIG. 7 (B), a punched part 19 is formed so that the window frame can be mounted inside, or as shown in FIG. 7 (C), a window frame 20 is interposed in the middle, and In order to fix the window frame 20, the heat insulating panel 21 having the lower surface made of the wooden member 6A, the heat insulating panel 22 having the upper surface made of the wooden member 6B, and the like are configured by replacing some frame materials with the wooden members 6A and 6B. it can. In any case, the regulating member 25 is provided at a location where the shrinkage of the dimension between the left and right frame members 2, 2 becomes a problem, and in any case, the side flange portion 1a of the face material 1 is shown in FIG. By being fixed to the pillar 11 by the fixing tool 12 as in the case shown,
The warp in the height direction is corrected.

In the present invention, for example, as the frame members 2 to 4, a structure in which the flange portion d protruding to the outer periphery is eliminated is adopted, and the face member 1, the frame members 2 to 4, the wooden member 6, the regulating member 25 and the sheet 28 are used. Various changes and additions can be made to the structure and shape of each part of.

[0026]

According to the first aspect of the present invention, since the regulating member is provided between the left and right frame members, after the foam material is filled and cured,
Even if the foam material tries to shrink, the contracting member prevents the left and right frame members from contracting, so that the left and right frame members are prevented from contracting, which causes warpage in the width direction of the face material and the frame material. The generation is suppressed, and the warp in the height direction is also reduced to some extent. Furthermore, the warp in the height direction is suppressed by the wood member provided in the height direction, and the collar portion on the side of the face material is suppressed. It is corrected by fixing the to the column with a fixture. This prevents deterioration of the appearance and commercial value of the heat insulating panel. Further, the dimensional accuracy is improved, and the quality such as heat insulating property and airtightness is improved and stabilized. Further, since the OSB is used as the face material, the price of the heat insulating panel is reduced because the OSB is cheaper than the plywood bonded with the thin plate material. According to claim 2, since the rest member after the face material is cut out from the OSB raw material is used as the regulating member,
In addition to reducing the number of raw material parts, the material cost of the regulating member is unnecessary, and the heat insulating panel can be provided at a lower cost.
