Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a heat-insulating outer structural panel for constructing a wall excellent in workability and thermal environment in a framed house.

[0002]

2. Description of the Related Art Conventionally, in a wooden house in which a structural surface material is used for a wall in order to form a structure, the surface material is stuck to the outside and / or indoor surface of a framed column, and the column is not exposed. The so-called large wall construction method is performed. The reason for this is that a wall panel is used as a structural surface material, and is directly struck on a pillar to form a one-sided or two-sided surface material, whereby a desired strength that is 2 to 10 times as large as that of the braced structure can be obtained. is there.

[0003] By the way, in the braced structure, there is a problem that when a heat insulating material is to be installed in the wall, it takes much time and a desired heat insulating effect cannot be sufficiently obtained. A heat insulating material can be loaded into the space surrounded by the pillars, the horizontal members, and the inner and outer surface materials to perform the work, and a good heat insulating effect can be obtained.

[0004] There is a technology in which the above-mentioned heat insulating material is integrally attached to the panel so that the surface material can be attached and the heat insulating material can also be applied. A house using a conventional framed panel construction method is certified by the Japan Housing and Wooden Technology Center. It has also appeared in the wooden house rationalization certification system.

[0005] In recent years, one of the performances required for houses is air-tight insulation, which has become one of the standards required for high-performance houses for the purpose of improving cooling / heating efficiency and sound insulation. I have. To improve this tightness,
A framed panel construction method in which a panel is nailed directly to a framed structure is advantageous. For example, Japanese Patent Application Laid-Open Nos. Hei 7-32497 and Hei 8-41
It is generally known to attach an airtight packing material to a portion where a panel is incorporated into a shaft assembly, as disclosed in Japanese Patent Publication No. 37-37.

However, in this case, it is necessary to attach a packing material separately from the heat insulating material, which not only takes time and labor to assemble, but also when glass wool or polyethylene is used as the heat insulating material, for example, There was a problem that the packing material could not be securely bonded.

Further, if the airtightness is improved only by using the heat insulating material without using the above-mentioned packing material, a high accuracy is required for the dimensions of the frame and the heat insulating material, and the construction when the panel is incorporated into the shaft material is required. Also worse. That is, there is a problem in that if the gap is large, the airtightness is reduced, whereas if the gap is eliminated, it is difficult to fit the gap.

In order to solve the above-mentioned problem, for example, as shown in FIG. 8, there is known a panel c in which a heat insulating material a in which a peripheral side surface a1 is tapered and cut off is adhered to a surface material b. However, in this case, it is easy to fit the panel c into the shaft member d. However, if the dimensional accuracy is poor, as shown in FIGS. The material b is sandwiched between the tapered side surfaces a1, and the surface material b
However, there is a possibility that desired wall strength may not be obtained due to the fact that the material does not come into close contact with the shaft member d (FIG. 10 shows the state in an enlarged manner).

As means for solving this problem, Japanese Patent Application Laid-Open No. Hei 8-1
As disclosed in Japanese Patent No. 77140, a notch groove is formed from the back side near the outer peripheral taper side of the heat insulating material adhered to the back material on the back surface, and the tapered side surface is removed so that the notch groove is eliminated in a mounted state of the panel. Has been proposed in which the cut groove is formed as a gap preventing portion by deforming the groove.

[0010]

However, in this proposal, it takes time and effort to make a cut groove in the heat insulating material.
There is a drawback that panel manufacturing efficiency is poor. In addition, since the heat insulating material has low strength and is easily broken, there is a possibility that the heat insulating material may break from the cut groove during handling and may be damaged, and thus lack reliability.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to solve the above-mentioned problems while having the same workability as that of the related art, and being extremely easy to manufacture. An object of the present invention is to provide a heat-insulating outer structural panel suitable for constructing a wall excellent in workability and thermal environment in a construction house.

[0012]

In order to achieve the above object, according to the present invention, the peripheral side surface of the heat insulating material is not cut off in a tapered shape as in the prior art, but instead, the distance between the opposing side surfaces is reduced. Was cut out in an inversely tapered shape so as to gradually increase as the distance from the face material increased.

More specifically, according to the first aspect of the present invention, the heat-insulating outer structural panel, which is attached from the outdoor side to the space between the horizontally adjacent columns and between the vertically adjacent horizontal members, forms the wall. And an outer structural surface member mounted between the horizontal members from the outdoor side, and integrally attached to an intermediate portion of the indoor side surface of the outer structural surface member, and opposing left and right side surfaces and upper and lower side surfaces are respectively provided between the columns and the horizontal members. And a heat insulating material inserted between the members.

[0014] In the heat insulating material, the opposing left and right side surfaces and the upper and lower side surfaces are each formed as an inversely tapered surface in which the distance between the opposing side surfaces gradually increases as the distance from the outer structural surface material increases. In addition, the minimum distance between the left and right side surfaces forming the reverse tapered surface of the heat insulating material is smaller than the distance between the opposing surfaces of the left and right pillars, and the minimum distance between the upper and lower side surfaces is smaller than the distance between the opposing surfaces of the upper and lower horizontal members. On the other hand, the maximum distance between the left and right side surfaces is set larger than the distance between the opposing surfaces of the left and right pillars, and the maximum distance between the upper and lower side surfaces is set larger than the distance between the opposing surfaces of the upper and lower horizontal members.

According to the second aspect of the present invention, a stud is integrally attached to a center portion of the outside structural surface member on the indoor side surface in a state where the heat insulating material is divided. The stud is attached between the upper and lower horizontal members by oblique driving of a nail or the like.

According to the configuration of the first or second aspect of the present invention, the distance between the opposed side surfaces gradually increases as the opposed left and right side surfaces and upper and lower side surfaces of the heat insulating material are separated from the outer structural surface material. Therefore, when installing the panel between the left and right pillars and the upper and lower horizontal members, the reverse tapered side surface of the heat insulating material is inserted while being deformed, and the panel is easily assembled.

The minimum distance and the maximum distance between the left and right sides forming the reverse tapered surface of the heat insulating material are on both sides of the distance between the opposing surfaces of the left and right pillars, respectively, and the minimum distance and the maximum distance between the upper and lower sides are respectively provided. Are also located on both sides of the distance between the opposing surfaces of the upper and lower horizontal members, so on the tapered side surfaces around the heat insulating material, between the opposing surfaces of the left and right adjacent columns and the opposing surfaces of the upper and lower adjacent horizontal members The portion larger than each distance between them is partially crushed during the insertion and comes into close contact with the column and the transverse member, respectively.
In addition, the face material always comes into close contact with the pillar and the horizontal member, and thereby the airtightness of the wall is improved.

Further, since the panel is formed by simply cutting the peripheral side surface of the heat insulating material to be attached to the face material into a reverse taper shape, the panel can be easily manufactured.

According to the third aspect of the present invention, the outer structural face material and the heat insulating material are adhered to each other with an adhesive applied in a dotted or linear manner. In this way, for example, when the heat-insulating outer structural panel itself is cut to required dimensions and used, when cutting the side surface of the heat insulating material at the cut end surface of the cut panel into an inverse tapered shape like the other side surfaces, an extra It becomes easy to peel off the heat insulating material from the face material.

[0020]

(Embodiment 1) FIG. 1 shows a heat-insulated outer structural panel P according to Embodiment 1 of the present invention. This panel P is a rectangular plate and is shown in FIGS. In addition, between the pillars 11 and 11 (tube pillars and corner pillars) adjacent to the left and right and between the body difference 12 and the base 13 (both horizontal members) vertically adjacent to each other, the outdoor side (the lower side in FIGS. 2 and 4). , 3 and 5) to form a wall.
In addition, each outdoor surface of each pillar 11, body difference 12, and base 13 is arranged flush with each other.

The heat-insulating outer structural panel P comprises a rectangular plate-shaped outer structural face material 1 and a heat insulator 5 attached to the indoor side face of the face material 1. The left and right dimensions of the outer structural panel 1 are set to be the same as the distance between the centers of the columns 11 and 11, and the upper and lower dimensions are set to be the same as the distance between the centers of the body gap 12 and the base 13, respectively. As shown in FIG. 5, the outer peripheral edge of the face material 1 is arranged so as to cover half of each of the exterior surfaces of the pillars 11, 11, the body gap 12, and the base 13. The nails N, N,... (Or may be screws) on the outdoor surface of the pillars 11, 11, body gap 12 and base 13 from the outdoor side.

L, volcanic glassy multi-layer plate, etc.,
Any surface material that can be directly nailed (or screwed) to the body difference 12 and the base 13 (body) and exhibit desired wall strength may be used.

On the other hand, the heat-insulating material 5 is a rectangular plate-like material whose top, bottom, left and right dimensions are both smaller than the outer structural face material 1, and is integrated with each of the upper, lower, left and right intermediate portions on the indoor side surface of the face material 1. It is attached. As the heat insulating material 5, for example, glass wool, insulation board, low-density wood fiber board, polystyrene foam, polyethylene foam, phenol foam and the like are desirable. Further, the face material 1 and the heat insulating material 5 are partially adhered to each other by an adhesive (not shown) applied in a dotted or linear manner.

In the heat insulating material 5, the left and right columns 11,
The right and left side surfaces 5a and 5b in contact with the
The upper and lower side surfaces 5c, 5c, which contact the upper and lower body difference 12 and the base 13 on the reverse taper surface which gradually increases as the distance between the a and 5b are separated from the outer structural surface material 1 (from the outdoor side toward the indoor side). Similarly, 5d is also formed as an inversely tapered surface in which the distance between the upper and lower side surfaces 5c and 5d gradually increases as the distance from the outer structural surface material 1 increases.

Of the distance between the left and right side surfaces 5a and 5b forming the reverse tapered surface of the heat insulating material 5, the minimum distance Dmin of the heat insulating material 5 on the outdoor side surface 5e (the surface on the surface material 1 side) is determined by the right and left columns. The distance Dmax between the opposing surfaces 11a, 11a is smaller than the distance D between the opposing surfaces 11a, 11a, and the maximum distance Dmax on the indoor side surface 5f (the surface opposite to the surface material 1) is equal to the opposing surfaces 11a, 1
1a are set to be larger than the distance D between them (D
min <D <Dmax).

On the other hand, of the distance between the upper and lower side surfaces 5c and 5d forming the inversely tapered surface of the heat insulating material 5, the minimum distance Hmin of the heat insulating material 5 on the outdoor side surface 5e is equal to the upper and lower body difference 12 and the base 1
3 is set to be smaller than the distance H between the opposing surfaces 12a and 13a, and the maximum distance Hmax at the indoor side surface 5f is set to be larger than the distance H between the body difference 12 and the opposing surfaces 12a and 13a of the base 13. (Hmin <H <Hmax).

Therefore, the panel P of this embodiment is
In the case of mounting between the columns 11 and 11 adjacent on the left and right and between the body gap 12 and the base 13 adjacent on the upper and lower sides, FIG.
As shown in FIG. 3, the heat insulating material 5 on the indoor side surface of the panel P is inserted between the left and right pillars 11 and 11, between the upper and lower body gaps 12 and the base 13 from the outside of the room, The outer peripheral edge of the face material 1 on the outer peripheral side is
And in contact with the outdoor surface of the base 13, and in that state, FIG.
As shown in FIG. 5 and FIG.
1. It may be attached to the body difference 12 and the base 13 by nailing (or screwing). This allows the left and right pillars 11, 11
The panel P is laid over the space between the upper and lower body difference 12 and the base 13 to form a wall.

At this time, the left and right side surfaces 5a,
5b and the upper and lower side surfaces 5c and 5d are reverse tapered surfaces in which the distance between the left and right side surfaces 5a and 5b and the distance between the upper and lower side surfaces 5c and 5d gradually increase as the distance from the outer structural surface material 1 increases. 5 left and right side surfaces 5a, 5 forming an inverse tapered surface
b, the minimum distance Dmin and the maximum distance Dmax are on both sides of the distance D between the opposing surfaces 11a, 11a of the left and right columns 11, 11, and the minimum distance Hmin and the maximum distance Hmax between the upper and lower side surfaces 5c, 5d. The panel P is installed between the left and right pillars 11 and 11 and between the upper and lower body difference 12 and the base 13 because the upper and lower body difference 12 and the base 13 are located on both sides of the distance H between the opposing surfaces 12a and 13a. In this case, the distance between the opposing surfaces 11a, 11a of the left and right pillars 11, 11 and the distance between the opposing surfaces 12a, 13a of the base body 13 and the base 13 on the peripheral side surfaces 5a to 5d of the heat insulating material 5 The peripheral edge of the tip is partially crushed and inserted while being deformed from an inverted tapered surface shape. By doing so, the panel P can be easily assembled.

In addition, in the assembled state of the panel P, as described above, the corners of the distal ends of the peripheral side surfaces 5a to 5d of the heat insulating material 5 are crushed and come into close contact with the columns 11, 11, the body gap 12, and the base 13, respectively. Moreover, the face material 1 is a pillar 11 and a body difference 12
Also, since it is in close contact with the outdoor side surface of the base 13, the airtightness of the wall can be improved by the close contact of the peripheral portion of the heat insulating material 5 and the face material 1.

Further, the panel P is obtained by attaching a heat insulating material 5 to the outer structural surface material 1, and the peripheral side surfaces 5a to 5d of the heat insulating material 5 are simply cut into reverse tapered shapes to form reverse tapered surfaces. Therefore, the production of the panel P is also easy.

Further, since the heat insulating material 5 is adhered to the indoor side surface of the outer structural face material 1 by an adhesive applied in a dotted or linear manner, the following effects can be obtained. That is,
When a part of the heat-insulating outer structural panel P is cut and used for the purpose of changing the dimensions of the heat-insulating outer structural panel P, the side surface of the heat-insulating material 5 on the cut end face of the cut panel P is formed into an inverted tapered shape like other side surfaces. However, at this time, since the heat insulating material 5 is adhered by an adhesive applied in a dot-like or linear manner, the surplus heat-insulating material 5 that has been cut in the reverse taper shape is left over. The panel P can be easily peeled off and removed, and the processing of the panel P becomes easy.

(Embodiment 2) FIGS. 6 and 7 show Embodiment 2 of the present invention (note that the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals and detailed description thereof is omitted). The panel P has studs.

That is, in this embodiment, the body difference 12 and the base 13
A vertically extending stud 2 having a length substantially the same as the distance H between the opposing surfaces 12a and 13a is integrally attached, and left and right heat insulating materials 5 are respectively attached to the outer structural face materials 1 on both sides of the stud 2.
5 is attached. The two heat insulating materials 5 and 5 have a shape in which one heat insulating material 5 of the first embodiment is divided right and left by the studs 2 and removed by the left and right widths of the studs 2. 5d is a reverse tapered side surface as in the first embodiment. The stud 2 is attached to the body difference 12 and the base 13 at the upper and lower ends thereof by slanting nails or the like.

Therefore, in this embodiment, the same operation and effect as in the first embodiment can be obtained.
Note that the stud 2 can be attached to the face material 1 in the left-right direction.
