Description

Detailed Description of the Invention

[0001]

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. 9, a conventional heat insulating 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 the outer circumference of the heat insulating material 32 and the inner wall of the wooden frame 31 are separated from each other. 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. 10, left and right frame members 2 as vertical frame members and upper and lower frame members 3 as horizontal frame members are fixed to the indoor side plate surface of the bearing wall surface member 1 by a tacker or the like. 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. Has been developed and proposed as Japanese Patent Application No. 6-142351.

[0005]

However, in the heat insulating panel shown in FIG. 10, after the foam material 7 is filled in the space surrounded by the face material 1 and the frame materials 2 to 4, the foam material 7 shrinks (this The shrinkage starts 1 to 2 days after the heat insulating panel is manufactured, and is substantially subsided in about 2 weeks to 1 month.) The foam material 7 fixed to the frame materials 2 to 4 pulls the frame materials 2 to 4. Therefore, the frame members 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. It is intended to provide a structural insulation panel.

[0007]

The heat insulating panel of the present invention comprises:
A vertical / horizontal frame member made of synthetic resin for filling a foam material is fixed to the indoor side surface of the bearing material for the load-bearing wall so that the foam material filling portion constituted by the frame material is narrower than the face material. Prevents warpage in the width direction of the heat insulating panel by using the flange for panel mounting around the face material and preventing the dimension between the frame members fixed to the face material from shrinking in dimension. A foaming material is filled in the inner space surrounded by the frame material and the face material and cured, and the left and right flanges of the face material are fixed to the outdoor side surface of the building pillar by a fixture. By doing so, warpage in the height direction of the heat insulating panel is prevented.

[0008]

In the heat insulating panel of the present invention, since the regulating member is provided between the left and right frame members to prevent the dimension between the frame members from shrinking,
After the foam material is filled and hardened, even if the foam material tries to shrink, the restriction member prevents the left and right frame materials from shrinking, so that the foam material adheres to the left and right frame materials and face materials. Of the face material is suppressed, and thus the warp of the face material in the width direction is suppressed. Further, since the left and right brim portions of the face material are fixed to the pillar by the fixing tool, the warp in the height direction is corrected.

Left and right flanges 1a for mounting the panel and upper and lower flanges 1b, 1c are formed around the periphery.

Reference numeral 25 is a regulating member provided by the present invention. The regulating member 25 of this embodiment is produced by cutting wood into a length equal to the distance between the inner surfaces of the left and right frame members 2, 2. Yes, the recessed portion 6a provided in the wooden frame 6 is fitted with the recessed portion 25a in the central portion of the regulating member 25 and fixed with a fixture 26 such as a nail or a screw, and both ends of the regulating member 25 are applied to the inner surface of the frame member 2. It is attached by fixing with a fixture 27 such as a tucker. Other than this, the same material as the face material 1, resin, metal, fiber-reinforced molded body, or the like can be used as the regulating member 25.

The heat insulating panel of this embodiment is manufactured by fixing the frame members 2 to 4, the wooden frame 6 and the regulating member 25 to the face material 1,
The 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 periphery of the frame materials 2 to 4 and the release paper 28 are pressed by a mold (not shown) to foam. It is produced by pouring the material 7 into the internal space in a fluidized state and curing it.
The foam material 7 includes surrounding members, that is, the face material 1 and the frame material 2 to 2.

As shown in the cross-sectional views of FIGS. 1 and 6, the inner peripheral surface of the frame, that is, in the case of the vertical frame member 2, the side surface of the pillar (including the stud) 11 (the upper frame member 3). In the case of, the lower surface of the upper horizontal member 40 composed of a girder or a girder is brought into contact with the lower frame member 4, and in the case of the lower frame member 4, the upper surface of a lower horizontal member 41 composed of a girder or a girder is contacted. In case of frame material 2, pillar 11
Of the face material 1 by contacting it with the outer surface (the outer surface of the upper horizontal member 40 in the case of the upper frame member 3 and the outer surface of the lower horizontal member 41 in the case of the lower frame member 4) of The left and right flanges 1a are fixed to the pillar 11 by a plurality of fixing tools 12 such as nails, and the upper and lower flanges 1a
b and 1c are also provided with a plurality of fixtures 12 for each upper cross member 4
0, fixed to the lower cross member 41.

In the example of FIG. 6, a furring strip 14 for mounting an exterior material 13 such as siding is attached to the wooden frame 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.
As for the warp of the frame members 2 to 4 in the height direction, the left and right flanges 1a of the face member 1 are fixed to the pillars 11 by the fixing tool 12, and are pressed by the fixing tool 12 as shown by an arrow F. Will be corrected 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.

FIG. 7 is a cross-sectional view corresponding to FIG. 4 showing another embodiment of the present invention. As the restricting member 42, a plurality of plate members are installed between the left and right frame members 2 and 2, and the restricting member 42 is provided. And face material 1
And a space is formed between them. According to the present embodiment, the gap is formed between the face material 1 and the regulation member 42, so that the regulation member 42 interferes when the resin is filled between the face material 1 and the frame members 2 to 4. However, there is an advantage that the number of steps of the resin filling process can be reduced. In addition, the regulation member 25
By using the same material as the face material 1, the number of raw materials can be reduced.

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 shafts, there is no wooden frame 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. 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, and In order to fix the window frame 20, the heat insulating panel 21 having a lower surface of the wooden frame 6A, the heat insulating panel 22 having the upper surface of the wooden frame 6B, and the like have a part of the frame material of the wooden frame 6
It can be constituted by substituting A and 6B. In any case, the regulating member 25 (42) 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 collar portion 1a on the side of the face material 1 is By being fixed to the pillar 11 by the fixing tool 12 as in the case shown in FIG. 1,
The warp in the height direction is corrected.

In the present invention, the structure of each of the face material 1, the frame members 2 to 4 and the regulating members 25 and 42 is adopted, for example, by adopting a structure in which the flange portion d protruding to the outer periphery is eliminated as the frame members 2 to 4.
Various changes and additions can be made to the shape.

[0026]

As described above, according to the present invention, since the regulating member is provided between the left and right frame members to prevent the dimension between the frame members from shrinking,
After the foam material is filled and cured, even if the foam material tries to shrink, the contraction member prevents the left and right frame materials from contracting, which prevents the left and right frame materials from contracting. The occurrence of warp in the width direction of the frame and frame material is suppressed, and the warp in the height direction is also reduced to some extent.Furthermore, the warp in the height direction is fixed by fixing the collar part on the side of the face material. It is corrected by fixing it to the pillar. 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.
