However, such a wall structure of the frame construction method uses many components such as a heat insulating material and a structural material, and the heat insulating material is a rock wool heat insulating material, separately from the structural material. Alternatively, it uses a plate-shaped heat insulating material obtained by cutting foamed heat insulating material into the required shape and packs it between the interior and exterior base materials, so it lacks airtight heat insulation properties, and various connections to maintain airtight heat insulation properties Processing is also complicated, requires skilled skills, and has problems in terms of workability and cost.

Accordingly, the present invention aims to solve the above-mentioned problems by constructing a structural heat insulating panel having high strength, low cost and excellent in hermetic heat insulating properties and workability, and stably supplying a good wooden house using the structural heat insulating panel.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, the same reference numerals are used for the same elements, and duplicate descriptions are omitted.

<Embodiment 1> FIG. 1 is a partial perspective view showing an embodiment of a structural heat insulating panel and a wooden house wall structure according to the present invention. A structural heat insulating panel 1 shown in FIG. 1 is a polystyrene molded into a predetermined shape using a structural face plate 2 made of a structural plate (OSB) having a structural strength by compressing and molding a wood chip or the like with directionality. A foamed heat insulating plate 3 made of foamed heat insulating material (EPS) is bonded to a substantially central portion of the structural face plate 2 while leaving a peripheral portion 2a of the structural face plate 2 to form an integrated long panel. is there.

The lateral dimensions of the structural face plate 2 are shown by columns 4 and 4 in FIG.
Is slightly shorter than the center-to-center distance, and the vertical dimension of the structural face plate 2 is larger than the inner dimensions of the base 5 and the trunk 6 as the horizontal members, and a so-called fixed peripheral edge for fixing to these. The dimensions are such that the portion 2a can be secured. Further, the lateral dimensions of the foam-molded heat insulating plate 3 are slightly larger than the inner dimensions of the columns 4, 4, and the vertical dimensions thereof are slightly larger than the inner dimensions of the base 5 and the trunk 6. The foamed heat insulating plate 3 is adhered to a substantially central portion of the structural face plate 2. When the structural heat insulating panel 1 is fitted between the shaft sets A including the pillars 4, 4, the base 5, and the trunk 6. Can be fixed by nailing the foamed heat insulating plate 3 into the overlapping portion of the peripheral edge portion 2a of the structural face plate 2 with the columns 4, 4, the base 5, and the trunk 6.

The foam molded heat insulating plate 3 is processed to a thickness within a predetermined range. That is, when the foamed heat insulating plate 3 is too thin, the heat insulation performance of the wall structure using the foamed heat insulating plate 3 is extremely reduced. Conversely, when the foamed heat insulating plate 3 is too thick, a stud is provided as described later. It does not fit well when using structural insulation panels. The thickness of the foam-molded heat insulating plate 3 is set so that the air layer is interposed even if the thickness of the stud changes due to the distinction between the large wall structure and the true wall structure.

Here, as shown in the partial plan sectional view of FIG. 2A, both outer side surfaces 3a and 3b of the foam-molded heat insulating plate 3 are processed into a corrugated shape. A
When the foamed heat insulating plate 3 is fitted and fitted between the shaft sets A, the corrugated surface portions of the outer side surfaces 3a and 3b are easily deformed and fitted. Airtight insulation can be secured. Since the foamed heat insulating plate 3 is bent by its own weight, the foamed heat insulating plate 3 can be easily fitted between the frame sets A in the vertical direction. Although it is not necessary to perform the application, when the vertical dimension of the foam-molded heat insulating plate 3 is increased, it is desirable to form the upper surface 3c into a corrugated shape as shown in the partial side sectional view of FIG. FIG. 2 (3) shows a partial side cross-sectional view when the upper surface 3c is not processed into a waveform.

Further, the shape of the corrugated surface is not limited to the shape shown in FIG. 2, but may be one shown in FIGS. 3 (1) to 3 (3) as another example. As described above, this corrugated surface is formed because the foam-molded heat insulating plate 3 slightly larger than the inner dimension of the frame A easily fits between the frames A, and its deformation is elastic after the fitting. It is formed for the purpose of ensuring the air-tight insulation between the frames A by returning to the original shape, so that any shape that can achieve this purpose may be used. It is desirable to minimize the contact area between the top and the frame A.

The corrugated surface may be cut by a cutter or the like, but is preferably foamed in advance from the viewpoint of processing time and quality. However, in this case, the shape and size of the target object are limited due to restrictions in foam molding and the like. FIG. 4 shows an example of a piece layout diagram of the foam-molded heat insulating plate 3 in which these are comprehensively considered.

The foam-molded heat insulating plate 3 shown in FIG. 1 is constituted by attaching a left piece (3A to 3C), a right piece (3D to 3F), and a middle piece (3G, 3H). The reason why the left piece, the right piece, and the middle piece are divided into three parts is that the left piece and the right piece each have an outer surface for forming a corrugated surface, and the middle piece has such a processing surface. Since these pieces do not have, the productivity is improved as a whole when both of them are manufactured in a separate process and united. Therefore, the left piece and the right piece are each integrally formed by foaming, including the corrugated surface, and the middle piece is simply a cut of a normal fixed-size object.

The reason why the left piece (3A to 3C) and the right piece (3D to 3F) each have an upper, middle, and lower three-piece configuration, and the middle piece (3G, 3H) has an upper and lower two-piece configuration is as follows. This is because the standardized dimensions of general-purpose products of the foam-molded heat insulating plate 3 and the dimension system of the wooden house were weighed to maximize the material yield. However, the piece allocation of the foam-molded heat insulating plate 3 is not limited to this, and is appropriately determined in consideration of the dimensional system of the target building.

The above-described structural heat insulating panel 1 has a very simple structure in which a foamed heat insulating plate 3 having a predetermined shape is attached to one surface of the structural face plate 2 using an adhesive.
The inventor has confirmed by experiments that it has sufficient strength for practical use, and if this is used under prescribed construction procedures, a building or building that conforms to the relevant laws and regulations, such as the Building Standards Law, etc. Part of the thing.

When boric acid is added or mixed in the production process, the foam-molded heat insulating board 3 becomes a termite-treated building member, and reduces damage caused by termites, which are natural enemies of wooden houses. Can be.

Next, a description will be given of a wooden house wall structure using the structural insulation panel 1 and a construction method thereof. In FIG. 1, the horizontal members such as the pillars 4, the bases 5, and the trunks 6 constituting the frame A of the wooden house use artificial drying materials, and joints and connections are precut at a factory. Assembled and constructed on site.

When the structural heat insulating panel 1 is mounted between the frames A composed of the pillars 4 and 4 and the horizontal members, ie, the base 5 and the trunk 6, the foam molded heat insulating plate 3 is attached to the frame from the outdoor side. A, and the peripheral portion 2 a of the structural face plate 2 is brought into contact with the shaft set A such as the column 4. As described above, at least both outer side surfaces 3a and 3b of the foam-molded heat insulating plate 3 and, if necessary, the upper surface 3c are formed into a corrugated shape, so that the foam-molded heat insulating plate 3 is easily fitted and deformed into an irregular shape. Without impairing the airtightness, the pillars 4, 4 and the base 5,
Adhere to That is, as shown by the imaginary line, the structural heat insulating panel 1 can be airtightly fitted between the frames A at the foamed heat insulating plate 3 to form a heat insulating wall structure,
The peripheral portion 2a of the structural face plate 2 abuts against the frame A and is nailed and fixed, whereby this wall portion can be formed as a bearing wall. Further, on the indoor side, an interior base material 7 such as a plaster board material is provided.
Can be formed in a state in which it is attached to the pillars 4 and 4 in a state of being in contact with the pillars 4, 4, so that a wall structure having an air layer sealed as a heat insulating layer between the foamed heat insulating plate 3 and the interior base material 7 can be formed.

The structural heat insulating panel 1A shown in the figure is disposed above the window opening 8. Here, the height of the foam-molded heat insulating plate 3 is precut to exactly match the vertical dimension between the trunk 6 and the lintel 9, and the outer side surfaces 3a, 3
As in the case of the structural heat insulating panel 1, the width between the b is slightly larger than the dimension between the left and right pillars 4 and 4, and the outer surfaces 3a and 3b are formed as corrugated surfaces. Further, the structural face plate 2 has a sufficient height and width so that the peripheral edge portion 2a becomes a joint portion which is nailed and fixed to a frame such as the pillars 4 and 4 constituting the window opening 8. Although not shown, a structural heat insulation panel similarly formed between the window base 10 and the base 5 below the window opening 8 is attached.

Further, such a wall structure can be similarly applied to an upper floor such as a second floor. In addition, if the horizontal members such as the girder and the girder are unified to have the same cross section without considering the upper load and the column spacing, the distance between the upper and lower horizontal members will be the same, and the same bearing wall will be used. A well-balanced wall around can be constructed, and furthermore, by forming the second floor as a rigid floor resistant to horizontal load, the forces such as wind pressure and earthquake are dispersed and received throughout the building through the rigid floor and the bearing wall. There is an advantage that can be.

As shown in FIG. 5A, which shows a partial section of a two-story house, for example, the rigid floor is a second floor beam 11 supported by the trunk 6 and a second floor supported by the second floor beam 11. The upper surface of the floor joist 12 is made to be the same surface, the interval between the floor joists 12 is reduced, and the structural plate 13 is attached to the upper surface so that the four circumferences are fixed to receiving members such as the second floor beam 11 and the trunk 6. Can be formed.

In the wall structure according to the present invention, as shown in FIG. 5A, the structural heat insulating panel 1 is attached between the base 5 and the girder 6 and between the girder 6 and the eaves girder 14, and the exterior exterior Since the foamed heat insulating plate 3 is adhered to the structural face plate 2 serving as a base material, the outer heat insulating system is used. Therefore, even if the structural face plate 2 comes into contact with external cool air, no dew condensation occurs in the wall.
Since the air layer 15 formed in the wall is sealed by the interior base material 7, it is hardly affected by the humidity of the outside air, and the air layer 15 acts as a heat insulating layer together with the foamed heat insulating plate 3. Therefore, this wall structure constitutes an excellent heat insulating wall structure.

FIG. 5 (2) is a partial side view of the two-story house shown in FIG. 5 (1), and shows the panel layout of the structural heat insulating panel 1. As shown in the figure, the structural heat insulating panel 1 is fixed with nails 16 via the peripheral edge 2a of the structural face plate 2 which comes into contact with the frame A. Naturally, the greater the number of nails 16, the greater the strength of the wall structure.
It is desired to reduce the number of the lines. Therefore, the four peripheral edges of the structural heat insulating panel 1 are nailed to the frame A at an interval of 100 (mm) or less, and in particular, the lower edge portion, specifically, the portion that comes into contact with the base 5 or the barrel 6 is fixed to two. When nails are fixed to the steps, they become compliant with relevant laws and regulations, such as the Building Standards Law, and serve as one standard for practical use.

The structural face plate 2, the foam molded heat insulating plate 3 in the wall, and the air layer 15 form a bearing wall having excellent heat insulating properties. The same applies to the case where one of the pillars 4 is formed of a half pillar.

FIG. 6 (2) shows a true wall type wall structure in which the structural heat insulating panel 1 is mounted between the columns 4, 4. The interior base material 7 is attached so that the front surface of the structural member 2 is exposed, and the structural face plate 2, the foam-molded heat insulating plate 3 in the wall, and the air layer 15 form a bearing wall having excellent heat insulating properties. In addition, when the space | interval between the pillars 4 and 4 is large, as shown by the phantom line, the structural insulation panel 1 can be attached as the intermediate pillar 18 using a half pillar flat.

The interior heat-insulating panel 1 is attached to the interior of the vehicle, and an interior base material 7 having a longer side is attached to the room side so as to cover the column 4. A receiving member 19 having a small cross section is attached to the striking portion of the structural face plate 2 of the structural heat insulating panel 1 by nailing so as to be flush with the other column 4.
The structural heat insulating panel 1 is attached between 9 and the other pillar 4. That is, the foamed heat insulating plate 3 is fitted and the structural face plate 2

FIG. 7 (2) shows a wall structure of a true wall type having a corner, in which a structural heat insulating panel 1 is attached to one of the pillars 4 by nailing the structural face plate 2, and the pillars 4 are mounted on the indoor side. The interior base material 7 is attached so as to be exposed. As a wall structure to be combined with this wall structure, a receiving member 19 having a small cross section is attached to the pillar 4 so as to be nailed to the striking portion of the structural face plate 2 so as to be flush with the other pillar 4. The structural heat insulating panel 1 composed of the structural face plate 2 and the foamed heat insulating plate 3 is attached by the receiving member 19 and the column 4, and the receiving members 17 are attached to the side portions of the columns 4 and 4, respectively. The interior base material 7 is nailed and attached to the receiving material 17 so that the pillars 4 and 4 are exposed inside. An air layer 15 is hermetically formed in the wall. When the column interval is long, the half column is used flat as shown by the imaginary line in the figure, and the intermediate column 18 is used.
It can also be.

FIG. 8A shows a wall structure used between the pillars 4 and 4 around the opening, such as around the opening.
(2) shows a large wall type wall structure with a small entrance at the corner that is connected to a normal series wall structure. Also in these cases, the configuration and construction method are shown in FIGS.
This is the same as that described for (1).

According to the present invention, the structural heat insulating panel 1 is efficiently produced in a factory having a good management system,
A wall structure is constructed by using the structural heat insulating panel 1. By combining with a frame A made of pre-cut artificial drying material, it is possible to provide a highly accurate and stable quality building structure skeleton. . In addition, despite having a very simple structure, the structural heat insulating panel 1 has sufficient strength for practical use, and can stably supply a high-quality wooden house at low cost.

<Embodiment 2> FIG. 9 is a partial perspective view showing another embodiment of a structural heat insulating panel and a wooden house wall structure according to the present invention. Structural materials such as the base 5, the pillar 4, and the trunk 6 constituting the frame A of the wooden house use artificial drying materials,
The joints and connections are processed by pre-cutting at the factory and assembled and constructed on site.

The structural heat insulating panel 1 to be attached to the frame A
B also uses a structural face plate 2 made of a structural plate material (OSB) having a structural strength by compressing and molding a wood chip or the like with directionality, and a half of an artificial dry material on one of the left and right central portions. A long panel in which a stud 20 formed of a pillar is fixed, and a foamed heat insulating plate 3 made of a polystyrene foamed heat insulating material (EPS) formed in a predetermined shape is symmetrically adhered to both sides of the stud 20 to be integrated. The peripheral edge 2a of the structural face plate 2 is formed as a joint which can be nailed to the left and right columns 4, 4 and the upper and lower horizontal members, ie, the trunk 6 and the base 5.

The studs 20 are precisely adjusted to the dimensions between the base 5 to be mounted and the girth 6 or between the girths 6 and a girder (not shown). The lower surface of the plate 3 is flush with the upper surface 3c, and the upper surface 3c is slightly higher.
The width between a and 3b is slightly larger than the width between the left and right pillars 4 and 4 to be attached, including the stud 20 in the sandwiched state. Then, FIGS. 10 (1) and (2)
As shown in the partial plan sectional view and the partial side sectional view of FIG. 5, both outer side surfaces 3a and 3b and the upper surface 3c of the foam-molded heat insulating plate 3 bonded to the structural face plate 2 with the studs 20 interposed therebetween are processed into corrugations. When the structural heat insulating panel 1B is fitted between the base 5, the columns 4, 4 and the body insert 6, the foamed heat insulating plate 3 has the corrugated surfaces of the outer surfaces 3a, 3b and the upper surface 3c. It is deformed and fitted easily, and the airtightness between the pillars 4 and 4 after fitting can be ensured. The first embodiment
(3), the corrugated surface may not be formed on the upper surface 3c of the foamed heat insulating plate 3 as shown in the partial side sectional view of FIG.

Further, the foam-molded heat insulating plate 3 is sufficiently thinner than the thickness in the front-rear direction of the stud 20 in which half pillars are vertically used, and an interior base material is attached to the front surface of the stud 20 as described later. At this time, a space, that is, an air layer, is hermetically formed between the foam-molded heat insulating plate and the interior base material. The thickness of the foam-molded heat insulating plate 3 is set such that the air layer is interposed even if the thickness of the stud 20 changes due to the distinction between the large wall structure and the true wall structure.

The structural heat insulating panel 1C shown in FIG.
On the one surface of the structural face plate 2, two studs 20, 20 and three foamed heat insulating plates 3, 3, 3 are attached. The heights of the foamed heat insulating plate 3 and the studs 20 are precut to exactly match the vertical dimension between the trunk 6 and the lintel 9, and the foamed heat insulation including the width of the two studs 20, 20 themselves. The width between the outer surfaces 3a and 3b of the plate 3 is slightly larger than the size between the left and right pillars 4 and 4, as in the case of the structural heat insulating panel 1B.
a and 3b are processed into a waveform. In addition, the structural face plate 2
The peripheral portion 2a has a sufficient height and width so as to be a joining portion to be nailed and fixed to frames such as the pillars 4 and 4 constituting the window opening 8. Although not shown, a structural heat insulation panel similarly formed between the window base 10 and the base 5 below the window opening 8 is attached.

As shown in FIG. 9, when the long structural heat insulating panel 1B is mounted between the columns 4, 4 and the frame A composed of the horizontal members, ie, the base 5 and the trunk 6, the studs are provided from the outdoor side. 20 and the foam-molded heat insulating plate 3 is pushed between the shaft sets A, and the peripheral portion 2a of the structural face plate 2 is brought into contact with the column set 4 and the four equal set A. As described above, since at least both outer side surfaces 3a and 3b of the foam-molded heat insulating plate 3 are processed into a corrugated shape, the foam-molded heat insulating plate 3 is easily fitted, and may be deformed into an irregular shape and impair airtightness. Instead, it closely adheres to the base 5, the pillars 4, 4 and the trunk 6. That is, this structural insulation panel 1B is
As shown by the phantom line, the frame A
The heat insulating wall structure can be formed by airtight fitting between the two. The peripheral portion 2a of the structural face plate 2 abuts against the frame A and is nailed and fixed, thereby fixing the wall portion to the stud 20. It can be formed into a bearing wall provided. Further, on the indoor side, an interior base material 7 such as a gypsum board is attached in a state in which it is in contact with the front surface of the stud 20, so that a heat insulating layer is provided between the foam-molded heat insulating plate 3 and the interior base material 7. A wall structure with a closed air layer can be formed.

Regarding the upper wall structure of the window opening 8,
Structural insulation panel 1C is attached to pillars 4 and 4 and
It is attached to the wall frame made of the lintel 9, but can be easily fitted by the corrugated surfaces formed on the side surfaces 3a and 3b of the foam-molded heat insulating plate 3, and the heat insulating wall structure is secured with airtightness. It can be formed into a bearing wall by nailing the structural face plate 2 to the wall frame. In addition, a structure having a closed air layer as a heat insulating layer in the wall can be provided by nailing and attaching the interior base material 7 to the indoor side. The same applies to the lower wall structure of the window opening 8.

Further, such a wall structure can be similarly constructed in the upper part of the second floor or the like. In addition, if the horizontal members such as the girder and the girder are unified to those of the same cross section without considering the upper load and column spacing, the distance between the upper and lower horizontal members will be the same, and the same bearing wall will be used. A well-balanced wall can be constructed, and furthermore, by forming the second floor as a rigid floor that is strong against horizontal load, the force such as wind pressure or earthquake is distributed throughout the building through this rigid floor and the bearing wall. There is an advantage that can be.

The structural heat insulation panel 1B can cope with the large wall type and the true wall type by changing the thickness of the stud 20 as described above. FIG. 11 shows a modification. FIG. 11A shows a large wall type wall structure in which the structural heat insulating panel 1B is mounted between the columns 4 and 4, and the studs 20 mounted on the structural face plate 2 are flush with the surfaces of the columns 4 and 4.
