Abstract

PROBLEM TO BE SOLVED: To improve the fitting workability, the airtightness, and the heat insulating property by filling and hardening the foaming material in an inner space between a panel frame and a sheet adhered to each side of the frame, and fixing a face plate thereto to prevent the warping of the heat insulating panel. SOLUTION: Sheets 8, 8 are adhered to a surface on the outdoor side of a frame 10 of a heat insulating panel and a surface on the indoor side, and the foamed material 9 is filled and injected in an inner space surrounded by the frame 10 and the sheet 8 on the outer surface on the outdoor side, and hardened to constitute a heat insulating panel body 2. The heat insulating panel body 2 is fixed to a face plate for a bearing wall consisting of a chip material, lauan material, or plywood by driving a fixing piece such as a nail into the frame 10 through the face plate 1. Because the foamed material 9 is filled and hardened in the condition where the face plate 1 is not fitted, and then, the face plate 1 is fitted to the frame 10, the warping of the face plate 1 due to shrinkage of the foamed material 9, and the warping of the panel body 2 due to the warping of the face plate 1 can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a face material, a frame, and a heat insulating material provided in the frame, and the portion assembled by the frame is fitted and mounted between the frameworks of a wooden building to provide heat insulation and airtightness. The present invention relates to a heat insulation panel for building a wall having excellent properties.

[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. The conventional heat insulation panel is shown in FIG.
As shown in the cross-sectional view of FIG. 1, a wooden frame 43 including left and right vertical frames 41, a middle frame 42, and upper and lower frames (not shown) is fixed to one surface of the face member 40 by a fixture 49 such as a nail, The foam material 4 serving as a heat insulating material in the internal space surrounded by the wooden frame 43, the face material 40, and the sheet 44 attached to the opposite surface side of the wooden frame 43.
5 is injected and filled and cured. Further, band-shaped sponges 46 and 47 as airtight materials are attached to the outer circumference of the wooden frame 43 and the inner circumference of the face material 40 on the indoor side, respectively.

[0003]

However, in the above conventional heat insulating panel, when the foam material 45 cures, the foam material 45 contracts while being fixed to one surface of the face material 40.
As shown by 1, the surface of the face material 40 on the wooden frame 43 side (the surface on the indoor side) contracts. This shrinkage phenomenon is completed in several tens of minutes after filling, which corresponds to a shrinkage amount of approximately 90% or more of the total shrinkage amount,
It will be completed in about one day.

On the other hand, as the face material 40, a face material for load-bearing walls made of chip material such as OSB (Oriented Structural Board) or lauan material is used. A small amount of water is brought into the factory from foreign countries, and the one with a water content of about 3% at the stage of manufacturing the heat insulation panel in the factory is gradually absorbed by moisture in the air when it is provided to the sales channel as the heat insulation panel. For example, the water content increases to about 10%, and due to this increase in the water content, the surface on the outdoor side of the face material 40 not constrained by the foam material 45 expands as indicated by an arrow X2.

Due to the shrinkage of the heat insulating material 45 and the expansion of the face material 40, the heat insulating panel warps as shown by a two-dot chain line,
When fixing the peripheral portion of the face material 40 of the heat insulating panel to the outdoor side surface of the frame with nails or the like, it is necessary to press the heat insulating panel by hand to correct the warp and perform work such as nailing. There is a problem in that it is difficult to mount the shaft on the frame, and if warpage remains, it takes time and effort to attach the exterior material on the outdoor side and the interior material on the indoor side. Further, due to the warp, the sponges 46 and 47 and the frame 48 are
There is a problem that a gap is apt to be formed between them and the airtightness and the heat insulating property are deteriorated.

In view of the above problems, it is an object of the present invention to provide a heat insulating panel which prevents warping of the heat insulating panel and can improve the mounting workability, airtightness and heat insulating property.

[0007]

According to a first aspect of the present invention, sheets are attached to the outer and inner surfaces of a frame of a heat insulating panel, and a foam material is provided in an inner space surrounded by the frame and the outer and inner sheets. It is characterized in that a heat-insulating panel body is formed by filling and injecting and curing, and the heat-insulating panel body is fixed to a surface material for a bearing wall.

According to a second aspect of the present invention, the heat insulating panel body is
It is characterized in that it is fixed to the surface material for the load-bearing wall by a fixing tool which is driven into the frame through the surface material.

[0009]

In the invention of claim 1, the space filled with the foam material is formed as a space surrounded by the frame and the sheets attached to the indoor and outdoor surfaces thereof.
Can be filled and cured without the face material attached,
Since the face material can be attached to the frame after the foam material contracts, it is possible to prevent the warp of the face material due to the contraction of the foam material or the warp of the heat insulating panel body caused by the warp of the face material.

According to the second aspect of the invention, the relative displacement between the frame and the face material, which occurs as a result of the expansion of the face material due to the improvement of the water content of the face material, is caused by the relative displacement of the face material, the frame and the fixtures such as nails. It can be absorbed, and the warp of the face material or the warp of the panel body caused by the warp of the face material can be prevented.

It is configured to be held by hot pressing, and the interior space surrounded by the sheet 8, the frame members 3 to 6 and the warp prevention plate 7 is filled with the foam material 9 and cured.

The warp prevention plate 7 prevents the vertical frames 3 and 3 from warping and contracting in the inward and outward directions when the foaming pressure is applied when the foam material 9 is filled and when the foaming material 9 is subsequently contracted. As shown in FIG. 3, both ends and an intermediate part are fitted into the recesses 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 fixture 30 such as a nail, a tacker, or a screw. It is installed by doing.

Reference numeral 11 is an airtight member attached to the outer peripheral surfaces of the frame members 3 to 5, and 12 is an airtight member attached to the inner surface of the outer peripheral portion of the face member 1. As shown in FIG. 5, the airtight material 11
Is a base portion 11a made of a hard resin such as a hard vinyl chloride resin which is a mounting portion for the frame members 3 to 5, and an airtight portion 11b made of a soft resin such as a soft vinyl chloride resin having a fin-like flexible elasticity. The base member 11a has a frame member 3 to
5 has mounting legs 11c that fit into the grooves 13 of FIG. The airtight material 11 includes a base portion 11a including legs 11c and an airtight portion 11
It is produced by co-pressing and b.

These airtight members 11 and 12 are frame members 3 to 5 respectively.
Alternatively, the airtight materials 11 and 12 which are provided over the entire length of each side of the face material 1 and are adjacent to each other at the end portions of the frame materials 3 to 5 or the corner portions of the face material 1 are butted against each other.

FIG. 6 is a manufacturing process chart of this embodiment. First, as shown in the front view of FIG. 6A and the side view of FIG. 6B, the frame members 3 to 6 and the warp prevention plate 7 are arranged. Nails, tuckers,
Assemble with a fixture 30 such as a screw. Grooves 13 are preliminarily processed on the outer peripheries of the frame members 3 to 5 before assembling.

Next, the front view of FIG. 6 (C) and FIG. 6 (D).
As shown in the side view of FIG. 1, the double-sided tape 14 is attached to the indoor and outdoor surfaces of the upper, lower, left and right frame members 3 to 5. Then, by fixing the peripheral portion of the sheet 8 to these double-sided tapes 14, the frame 10
The sheet 8 is attached to the indoor and outdoor surfaces of. The hollow body thus configured is fixed by hot pressing, and the frame member 3
~ 6, the foam material is injected and filled into the internal space surrounded by the warp prevention plate 7 and the sheet 8 to be cured. In this case, the warp prevention plate 7 prevents the middle portion of the vertical frame 3 from warping outward due to foaming pressure, and prevents the middle portion of the vertical frame 3 from warping inward due to contraction of the foam material. Further, the middle frame 6 prevents the upper and lower frames 4, 5 from warping in the vertical direction due to the foaming pressure and contraction.

Next, as shown in the front view of FIG. 6 (E), the groove 1 previously provided on the indoor and outdoor surfaces of the upper, lower, left, and right frames 3-5.
3, the leg 11c for mounting the airtight material 11 is fitted and mounted. 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 members 3 to 5 at intervals with a tacker 15 (see FIG. 6 (I)) or the like.

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

Thus, in the present invention, the foam material 9
Since the face material 1 can be attached to the frame after the contraction, the warp of the face material 1 due to the contraction of the foam material 9 or the warp of the heat insulating panel body 2 can be prevented. Further, the heat insulating panel body 2 and the face material 1 which are caused as a result of the expansion of the face material 1 due to the improvement of the water content of the face material 1
Relative displacement with respect to the face material 1 or the frame materials 3 to 6 can be absorbed by compression deformation or elastic deformation of the fixture 31 at the joint between the fixture 31 such as a nail, and as a result, warpage of the face material 1 and thus heat insulation. The warp of the panel body 2 can be prevented or reduced, and the warp of the entire heat insulating panel can be prevented or reduced.

In this heat insulating panel, as shown in FIGS. 2 to 4, the fin-shaped airtight portion 11b of the airtight material 11 is provided on the inner peripheral surface of the frame, that is, in the case of the vertical frame 3, a pillar (or a stud) 16 To the side surface (in the case of the upper frame 4, the lower surface of the girder or the barrel 17; in the case of the lower frame 5, the base or the upper surface of the barrel 18), the other airtight member 12 is used in the case of the vertical frame 3. Is abutted on the outdoor side surface of the pillar 16 (in the case of the upper frame 4, the outdoor side surface of the girder or barrel 17; in the case of the lower frame 5, the base or outdoor side surface of the barrel 18), the nail It is fixed to the frame by a fixing tool 32 such as. A furring strip 21 for mounting an 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 fixture 33 such as a nail. Further, the stud adjustment member 23 is attached to the indoor side surface of the middle frame 6 of the heat insulation panel by a fixing member 34 such as a nail, and the pillar 16 and the like and the stud and the stud adjustment member 23 are finished materials 24 such as a board. cover.

When such a heat insulating panel is attached, if there is no warp in the heat insulating panel, it is not necessary to hold it in order to correct the warp, and the heat insulating panel can be easily attached. Further, if there is no warp, the furring strip 21 and the exterior material 20 can be easily attached, and the labor for adjusting the thickness of the stud adjustment material 23 can be reduced, and the interior material can be easily attached. It goes without saying that the indoor and outdoor structure of the heat insulating panel may be modified in various ways other than this example.

If the airtight portion 11b of the airtight member 11 is made of a soft resin into a fin shape as in the present embodiment, the frame portion of the heat insulating panel which is assembled by the frame members 3 to 5 is pushed between the frames. As a result, the airtight portion 11b bends, and the airtight portion 11b
Since the airtight portion 11b comes into close contact with the surface of the framework such as the column 16 due to the elasticity of the airtightness, airtightness and heat insulation are secured. In addition, as compared with a conventional sponge, which expands and contracts in the thickness direction of the sponge to follow the size of the gap between the heat insulating panel and the frame, the airtight portion 11 having flexible elasticity is provided.
By following the size of the gap by the bending of b,
It can be used over a wide range of gaps, ensuring airtightness and heat insulation. Further, when a gap of, for example, about 15 mm at the maximum is formed between the frame members 3 to 5 and the frame due to an attachment error of the frame members 3 to 5 or a construction error of the frame, it is 15 mm.
When a sponge having a certain thickness is attached to the periphery of the frame members 3 to 5, it is difficult to insert the heat insulating panel between the frames when the gap is narrow or the bar is turned up, and the mass of the material is increased. However, by forming the airtight portion 11b in a fin shape as in the present 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.

Further, by constructing the heat insulating material with the foam material 9, the assembling work for incorporating 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 caulking material. There is an advantage that the process is simplified because the work of closing with is unnecessary. When the heat insulating material is formed by injecting and filling such a foam material, since the frame members 3 to 5 are made of the wooden, resin or concrete frame,
Unlike the case where 5 is composed 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 foaming material can be solidified. Will be easier.

As the material of the base portion 11a of the airtight material 11, polyethylene, polypropylene, polystyrene, ABS resin, polycarbonate, polyamide, polyphenylene oxide, etc. can be used in addition to the above-mentioned examples. As the material of the airtight portion (airtight material) 11b, in addition to the above examples, thermoplastic elastomer, plastic polyvinyl alcohol, etc. can be used, but other than these, as long as they fulfill the function of the base portion or airtight portion, respectively. 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 another embodiment of the present invention, and FIG. 8 is a cross-sectional view corresponding to GG in FIG. 1 of the embodiment.
Also in this embodiment, the sheets 8 are attached to both the indoor and outdoor surfaces of the frame members 3 to 5, and after the foam material 9 is filled and cured, the foam material 9 contracts and then the face material 1 is fixed by the fixture 31. In this example, the airtight member 35 attached to the indoor side is the base portion 3 made of the hard resin as described above, as in the above-described example.
5a and the airtight portion 35b made of a soft resin are co-pressed and integrally molded. The airtight material 36 attached to the outer peripheral portion of the face material 1 also includes a base portion 36a and a fin-shaped airtight portion 36b made of the same material as the base portion 35a and the airtight portion 35b, respectively. In the present embodiment, in order to facilitate the attachment of these airtight members 35 and 36, the base portions 35a and 36a are formed in a U-shaped cross section, and the frame members 3 to 5 or the outer periphery of the face member 1 are respectively formed. The structure is such that it is attached by fitting it into the part. In this embodiment, the seat 8 on the indoor side is attached after the airtight material 35 is attached to the frame members 3 to 5.

According to this embodiment, the frame member 3 of the airtight member 35
5 or the airtight material 36 is attached to the outer peripheral portion of the face material 1 in a U-shaped base portion 35a, 36a.
By fitting the outer peripheral portion of the frame members 3 to 5 or the face member 1 to each other, the attachment becomes very easy and the airtight members 35,
Since 36 is positioned by being fitted into the outer peripheral portions of the frame members 3 to 5 and the face member 1, it is mounted with high positioning accuracy, and there is no positional deviation as in the case of sticking, and airtightness,
Heat insulation is ensured.

Further, as in the present embodiment, the fixing strength of the airtight material 35 is improved by fixing the portion 35c that abuts the inner surfaces of the frame members 3 to 5 to the heat insulating material 7 by utilizing the adhesive force of the foam material. Go up. Further, it is not always necessary to use an adhesive or a fixing tool, and by simply setting the airtight material 35 on the frame members 3 to 5 and filling it with the foam material, the formation of the foam material 9 as the heat insulating material and the fixing of the airtight material 35 are performed. Since the airtight material 35 can be attached at the same time, the airtight material 35 can be easily attached.
Since the temporary fixing means of is not required, manufacturing and assembling can be facilitated.
It can be simplified. In addition, since the base portion 35a of the airtight member 35 is fitted to the frame members 3 to 5, the attachment strength of the airtight member 35 can be increased.

Further, as in the present embodiment, when the airtight members 35 and 36 are formed by separate members with respect to the frame of the pillar 16 or the like, each heat insulating panel for ceiling, floor or wall is constructed. In some cases, at least one of the airtight material 35 attached to the frame materials 3 to 5 and the airtight material 36 attached to the outer peripheral portion of the face material 1 can be used in common, and the manufacturing line and the parts management can be shared, which is economical. Can be achieved.

The structure of the airtight material can be variously modified in addition to the above embodiments. For example, as shown in FIG. 9A, the base portion 3 of the airtight material 36 attached to the outer peripheral portion of the face material 1.
By providing the fin-shaped airtight piece 36c on the inner surface of 6a in the longitudinal direction, it is possible to prevent air from passing through the gap between the airtight material 36 and the surface material 1 and improve the airtightness.

On the other hand, as shown in FIG.
The foam material 9 is attached to the base portion 35a of the airtight material 37 attached to
By providing the portion 37c that covers the surface on the indoor side of, the airtight material 35 can be fixed to the frame members 3 to 5 by utilizing the adhesive force of the foam material 9. Further, when the indoor side opening surface of the frame composed of the frame members 3 to 5, the middle frame 6 and the warp prevention plate 7 is closed, and the sheet 8 is applied to the airtight material 37 to fill the foam material,
The warp prevention plate 7 can be pressed and foamed by the airtight material 37, and the end portion of the warp prevention plate 7 can be closed by the airtight material 3.
Since it can be covered with the warp prevention plate 7, it suffices that the center of the warp prevention plate 7 be fixed to the middle frame 6 and that the end portion of the warp prevention plate 7 be brought into contact with the inner surface of the frame member 2 as shown in the drawing. 7
There is an advantage that it is not necessary to provide a recess for fixing the end of the frame member.

FIG. 9B shows a linear protrusion 36d on the inner surface of the base portion 36a of the airtight material 36 attached to the outer peripheral portion of the face material 1.
1 in which the projection 36d is provided in the face material 1 in the longitudinal direction.
By being fitted in a, the fixing strength of the airtight material 36 is increased, and the air flow is prevented from flowing through the gap between the airtight material 36 and the face material 1, so that the airtightness is improved. The airtight material 11 attached to the frame members 3 to 5 has the structure as described in the above embodiment.

FIG. 10A shows an airtight member 38 fitted to the outer peripheral portion of the face member 1, which is made of a soft resin such as vinyl chloride resin or a rubber airtight member as a whole. The uneven surface 38 is formed on the contact surface between the
Airtightness is ensured by forming a and 38b. Further, the airtight material 39 attached to the frame members 3 to 5 is obtained by attaching the base portion 39a attached to the frame members 3 to 5 to the sheet 8. Further, one or a plurality of fin-like airtight portions 39b made of a soft resin are integrally provided in an extended shape of the base portion 39a. Instead of adhering or welding the airtight material 39 on the sheet 8 as in the illustrated example, the portion covering the foam material 9 is directly attached to the foam material 9, that is, the airtight material 39 under the sheet 8. Alternatively, the heat insulating material 39 may be fixed by using the adhesive force of the foam material 9.

Further, the airtight material 50 of FIG. 10 (B) is one in which the airtight material provided on the frame members 3 to 5 and the airtight material provided on the outer peripheral portion of the face material 1 are integrated, and in the case of this example. , The airtight material 5
The base portion of 0 has a portion 50a to be applied along the corner portions of the frame members 3 to 5 and a portion 50c to be fitted to the outer peripheral portion of the face material 1, and the airtight portions 35b and 36b of FIGS. 7 and 8 respectively.
Airtight parts 50b and 50d made of the same material as the above are integrally provided on the base part. According to this example, the airtight material 3 shown in FIGS.
5, 36 can be manufactured at the same time, and the manufacturing process and the assembling process can be simplified.

Further, as shown in FIG. 11 (A), the soft or hard resin base portion 51a of the airtight member 51 is the face member 1
The air-tight member 51b has a width large enough to close the opening surface on the opposite side of the sheet, and the airtight portion 51b made of a soft resin is provided around the opening surface.
Can be omitted, and the number of parts can be reduced.

Also, as shown in FIG. 11B, even if the airtight member 52 has a hollow airtight part 52b made of a soft resin formed by co-pressing with the base part 52a, a manufacturing error or a construction error may occur. Flexibility that can absorb The hollow shape can also be applied to the airtight portion of the airtight material 36.

In each of the above examples, a soft resin can be used as the base portion of the airtight material, as with the airtight portion.

12 to 14 show another embodiment of the present invention. In this embodiment, as the frame members 3A to 5A, the same hard vinyl chloride resin as that used for the base portion is used, and the soft vinyl chloride mentioned above is used. This is manufactured by integrally pressing fin-shaped airtight portions e and f made of a soft resin such as resin. Structure part A of vertical frame 3A, upper frame 4A, lower frame 5A
Is an outer peripheral portion a that covers the periphery of the foam material 9 and integrally includes the airtight portion e, an exterior b and an interior portion c that respectively cover the exterior side and the interior surface of the periphery of the foam material 9, A flange portion d is formed so as to project outward from the outside b so as to be flush with the outside of the room b, and the airtight portion 10 is integrally provided.
As in the case of using the wooden frame, each of the frame members 3A to 5A has an inner frame 6 and a warp prevention plate 7 which are fixed to each frame by fixing tools 53, 54 such as tuckers, nails and screws. The frame members 3A to 5A are combined and prevented from warping due to shrinkage of the foam material 9. In this embodiment, the double-sided sheet 8 and the middle frame 6,
After the foam material 9 is filled and cured in the internal space surrounded by the warp prevention plate 7 to form the panel body, the face material 1 is fixed to the panel body by a fixture such as a nail, a screw, or a tacker, or by adhesion or the like. .

In the heat insulation panel shown in FIGS. 12 to 14, as a means for integrating the structural parts A (a to d) and the airtight parts e and f, as long as a process suitable for mass production can be taken. Of course, the frame members 3A to 5A may be integrated in the process of fitting or inserting the constituent members of the airtight parts e and f, which are separately manufactured, into the fitting part provided in the structure part. Since the airtight portions e and f can sometimes be integrated with the structural portions (a to d), the pasting work of the airtight material which is conventionally required is not necessary, which is suitable for mass production and the productivity can be improved. In addition, since it can be manufactured by extrusion molding of resin, the quality is stable compared to conventional products by cutting wood and fixing it to face material, and the airtight part e,
The dimensional accuracy of the position and size of f is improved. Further, since the frame members 3A to 5A can be formed thin with a thickness of about a fraction of that of wood, the cross-sectional area of the foam material 9 becomes larger than that of the conventional wood frame. Excellent in heat insulation and can be made lighter.

The present invention may be configured without the middle frame 6, a quadrangle in which one side is inclined with respect to the other side, or a triangle, instead of the right-angled quadrangle. In addition, a punched part is formed inside the heat insulating panel so that the window frame can be attached, the heat insulating panel with the lower surface as the middle frame and the upper surface with the window frame in the middle so that the window frame can be fixed. A heat insulating panel or the like having a middle frame can also be configured by replacing a part of the frame material with the middle frame.

[0042]

According to the first aspect of the present invention, the sheet is attached to the inside and the outside of the frame, the foam material is filled and cured in the frame, and the heat insulating panel body and the face material are fixed to each other. It is possible to prevent or reduce the warp of the face material due to the contraction of the material or the occurrence of the warp of the heat insulating panel body caused by the warp.

Since the warping of the heat insulating panel is prevented or reduced in this way, the heat insulating panel can be easily attached to the frame, and a gap is unlikely to be formed between the airtight material attached to the heat insulating panel and the frame. Therefore, airtightness and heat insulation are improved. Further, the reduction of the warpage of the heat insulation panel facilitates the attachment of the exterior material and the interior material.

According to the second aspect, the relative displacement between the frame and the face material caused by the expansion of the face material due to the improvement of the water content of the face material is absorbed by the relative displacement of the face material, the frame and the fixture such as a nail. Therefore, the warp of the face material or the warp of the panel body caused by the warp of the face material can be prevented more effectively.
