Abstract

PROBLEM TO BE SOLVED: To prevent delamination of a foamed material from a reinforcing member, and to prevent degradation of the strength of the entire building panel. SOLUTION: A room side surface S2 of a foamed material 3 has a thinned portion 5 formed thereon at a location separate from a stud 4. Further, a thickened portion 6 is formed between the thinned portion 5 and the stud 4, which portion 6 rests on the stud 4. Therefore, an area over which the foamed material 3 makes contact with the stud 4 is increased. Thus, even if a material (polystyrene) forming the foamed material 3 is poor in adhesiveness to the stud 4, delamination of the foamed material 3 from the stud 4 can be prevented.

2. Description of the Related Art For example, in the case of a wall of a wooden house in which an interior material and an exterior material are attached to a frame, various insulating materials are provided in a space formed by the interior material and the exterior material in order to improve heat insulation. It is common practice to place building panels. That is,
Architectural panels are typically used mounted between adjacent wooden columns. Therefore, the building panel is formed in a size corresponding to the width between columns on which it is to be constructed.

As shown in FIG. 19, this type of architectural panel 50 is provided with a face member 51 constituting an outer surface thereof. One stud 52 extending along the longitudinal direction of the panel is joined to the center of one side of the face material 51. Further, a foam material 53 having a heat insulating function is bonded to the face of the face material 51 on which the studs 52 are provided. This foam material 53
Is molded by filling a synthetic resin such as polyurethane into a mold (not shown) provided around the face material 51. Therefore, the foam material 53 is bonded not only to the face material 51 but also to the stud 52. Foam material 5
A thin portion 54 for passing indoor electric wiring is formed in the side surface 3. The thin portion 54 is recessed over the entire width of the building panel 50.

[0004]

However, in the conventional building panel 50, if the material for forming the foam material 53 is changed from polyurethane to another material, the adhesiveness of the foam material 53 to the studs 52 may deteriorate. is there. Moreover, since the thin portion 54 is in contact with the stud 52, the stud 5
The bonding area of the foam material 53 with respect to No. 2 was small. Therefore, there is a problem that the foam material 53 is easily peeled from the stud 52.

[0005] The thin portion 54 is recessed over the entire width of the building panel 50. That is, since most of the building panel 50 is the thin portion 54, if the material forming the foam material 53 is changed to a material having a lower strength than polyurethane, the strength of the entire building panel 50 decreases. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a first object of the present invention is to provide a building panel capable of preventing a foam material from peeling off a reinforcing member. is there. A second object is to provide an architectural panel capable of preventing a decrease in overall strength.

[0007]

According to a first aspect of the present invention, there is provided a foaming material provided between frames of a wooden house and having a thin portion at a predetermined position on an indoor side surface, and a reinforcing member. In the construction panel, the thin portion is formed at a position away from the reinforcing member, and a thick portion is provided between the thin portion and the reinforcing member.

According to a second aspect of the present invention, in the building panel according to the first aspect, the indoor side surface of the foam material is more protruding than the indoor side surface of the reinforcing member. .

The invention according to claim 4 is made of a foam material provided between the frames of a wooden house and having a thin portion at a predetermined position on the indoor side surface, which is relatively thinner than other portions. In the building panel, the gist is that the thin portion is formed at both end edges of the foam material, and a thick portion that is thicker than the thin portion is formed between the thin portions.

According to a fifth aspect of the present invention, in the building panel according to any one of the first to fourth aspects, the material of the foam material is polystyrene. .

According to a sixth aspect of the present invention, in the building panel according to any one of the first to fourth aspects, the expansion ratio of the foam material is set to 30 to 70 times. I do.

Next, the operation of the present invention will be described.
According to the first aspect of the invention, when the foamed material is changed to another material, the adhesiveness of the foamed material to the reinforcing member deteriorates. However, since the thick part is in contact with the reinforcing member, the bonding area of the foam material to the reinforcing member increases.
Therefore, since the adhesive strength of the foam material to the reinforcing member is increased, it is possible to prevent the foam material from peeling off from the reinforcing member. Also, most of the foam material is not thinner,
Even if the material of the foam material is changed to a material having a lower strength, the strength of the entire building panel does not decrease.

Therefore, it is possible to prevent dew condensation from occurring between the decorative material and the foam material. Further, since the foam material adheres to the decorative material, if the building panel is used, for example, as a heat insulating material, the heat insulating effect is enhanced.

According to the third aspect of the present invention, the work of fitting the building panel to the frame is facilitated. According to the invention described in claim 4, since most of the foam material is not a thin portion, even if the material of the foam material is changed to a material having low strength, the strength of the entire building panel is reduced. There is no.

According to the fifth aspect of the present invention, since the material for forming the foam material is made of polystyrene, when disposing of the foam material by dismantling a wooden house or the like, the foam material is incinerated or buried in a landfill. You do not have to dispose it like disposable. That is, it can be recycled.

According to the sixth aspect of the invention, the thermal conductivity can be reduced, and the strength of the foam material can be ensured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment in which a building panel of the present invention is embodied as a building panel for a wooden house will be described below with reference to the drawings.

FIG. 1 is a front view of a building panel 1 viewed from the indoor side of a wooden house. FIG. 2 is a plan sectional view of the building panel 1. As shown in FIGS. 1 and 2, the building panel 1
Is basically composed of a face material 2, a foam material 3 made of polystyrene, a stud 4, and the like.

The face material 2 constitutes the outer surface of the building panel 1 and has an outer dimension slightly larger than the foam material 3. The face material 2 is made of plywood (wood).

One wooden stud 4 extending in the longitudinal direction of the panel is joined to the center of one side surface of the face material 2. A foam material 3 having a heat insulating function is adhered to the face of the face material 2 on which the studs 4 are provided. The foam material 3
In other words, two studs 4 extend along the panel longitudinal direction.
It is divided into two. The foam material 3 plays a main part when the building panel 1 exhibits a heat insulating effect.

When assembling the building panel 1, the installation space K (see FIG. 4) surrounded by the columns 12 constituting the frame 11 of the wooden house and the horizontal members 13 such as beams and bases.
Then, the foam material 3 is fitted therein. In addition,
The width of the foam material 3 is formed to be slightly smaller than the width between the columns 12 so that the building panel 1 can be easily fitted into the frame 11. However, the gap between the foam material 3 and the column 12 is determined to be 5 mm or less according to the standard.

On the indoor side surface S2 opposite to the outdoor side surface S1 with respect to the face material 2 of the foam material 3, two thin portions 5 for passing electric wiring provided in a wooden house are recessed. Each thin portion 5 extends along the longitudinal direction of the stud 4, and is formed on both left and right edges of the building panel 1. That is, each thin portion 5 is formed at a position farthest from the stud 4 in the width direction of the hot wall panel 1. Then, the surface corresponding to the indoor side of the thin portion 5 and the left and right end surfaces S4, S6 of the foam material 3
The surfaces corresponding to are open. In this embodiment, the ratio of the width of the thin portion 5 to the width of the foam material 3 is set to 10 to 80%.

In the foam material 3, a portion other than the thin portion 5 is a thick portion 6 thicker than the thin portion 5. That is, in the foam material 3, the region between the thin portion 5 and the stud 4 and the regions at the upper and lower ends of the foam material 3 are all thick portions 6. As a result, portions that contact the left and right side surfaces of the stud 4 are thick portions 6. In this embodiment, the ratio of the thickness of the thin portion 5 to the thickness of the thick portion 6 is 2
It is set to 5 to 50%.

The indoor side surface S2 of the foam material 3 projects more indoors than the indoor side surface S12 opposite to the outdoor side surface S11 with respect to the face material 2 of the stud 4. Then, in a state where the building panel 1 is fitted in the installation space K in the frame 11,
The indoor side surface S2 of the stud 4 is arranged on the same plane as the pillar 12 and the horizontal member 13 or on the indoor side. Therefore, when the building panel 1 is fitted, the indoor side surface S2 of the foam material 3 is located closer to the indoor side than the columns 12 and the horizontal members 13.

In this embodiment, the indoor side surface S2 of the foam material 3 is 1 to 4 m from the indoor side surface S12 of the stud 4.
m is overhanging. More preferably, it is 1 mm to 2 mm. And the interior material which comprises a wooden house is pressed against the indoor side surface S2 of the foam material 3,
The indoor side surface S2 of the foam material 3 and the indoor side surface S12 of the stud 4 are flush.

As shown in FIGS. 1 to 4, the four upper and lower end surfaces S3 and S5 and the left and right end surfaces S4 and S6 of the foam material 3 are:
Each is composed of a vertical surface 3a and an inclined surface 3b. Each vertical surface 3 a is orthogonal to the outdoor side surface S <b> 1 with respect to the face material 2 of the foam material 3. Also, the vertical surface 3a
Is formed by a predetermined thickness from the outdoor side surface S1 of the foam material 3 to the indoor side surface S2. The cross-sectional area of the foam material 3 corresponding to the vertical surface 3a is equal in the thickness direction of the foam material 3.

On the other hand, the inclined surface 3 b is formed by the remaining thickness of the foam material 3. And the cross-sectional area of the foam material 3 corresponding to the inclined surface 3b becomes smaller toward the indoor side surface S2 of the foam material 3. In addition, each of the inclined surfaces 3b is visible from the indoor side surface S2 side opposite to the outdoor side surface S1.
Therefore, the area of the outdoor side surface S1 is larger than the area of the indoor side surface S2.

When the building panel 1 is fitted in the installation space K of the frame 11, the inclined surface 3 b is located closer to the indoor side than the columns 12 and the horizontal members 13. The angle θ between each vertical surface 3a and each inclined surface 3b is generally preferably 1 ° to 30 °,
More preferably, it is 3 ° to 20 °, and in particular, 5 °
It is preferable that the angle is from 10 to 10 °.

In this embodiment, a polystyrene foam is used as the material of the foam material 3. The reason for choosing polystyrene is as follows. First,
In addition, polystyrene foam can be recycled instead of being disposable when the foam material 3 is disposed of by dismantling a house or the like. Second, because polystyrene foam has fine and independent pores (discontinuous pores) inside, it causes moderate plastic deformation when pressed. In addition to the polystyrene foam, for example, a phenol resin, a silicone resin, a urea resin, a polyolefin, or the like can be used. Of course, these can be used in any combination.

The expansion ratio of the foam material 3 is set to 30 to 70 times. The reason for setting the magnification in this range is as follows. That is, if the expansion ratio is lower than 30 times, the number of air bubbles contained in the foamed material 3 is reduced, so that a large amount of polystyrene as a material is required. Therefore, the material cost of the foam material 3 is increased. On the other hand, if the expansion ratio is higher than 70 times, the thermal conductivity increases as the number of bubbles increases, and the heat insulating property decreases and the strength of the entire foam material 3 decreases. The expansion ratio of the foam material 3 is preferably set to 35 to 65 times, and more preferably within the range of 40 to 60 times.

As shown in FIGS. 1 and 4, positioning portions 7a and 7b are provided at upper and lower ends of the stud 4 so as to protrude along the longitudinal direction of the stud 4. Therefore, the positioning portions 7a,
Reference numerals 7b protrude outward from upper and lower end surfaces S3 and S5 of the foam material 3, respectively. The positioning portion 7 a is provided on the center line of the foam material 3. Such positioning part 7
a and 7b are made of the same material (wooden) as the horizontal member 13 constituting the shaft assembly 11.

The horizontal member 13 constituting the frame 11 of the wooden house
Has a pair of engaging portions 8 corresponding to the positioning portions 7a and 7b.
a, 8b are recessed. Each of the engaging portions 8a and 8b is formed at a central portion of each of the transverse members 13. Each of the engaging portions 8a and 8b extends along the mounting direction of the building panel 1 with respect to the shaft set 11, respectively. And
When assembling the building panel 1 to the shaft assembly 11, the positioning portions 7a and 7b are engaged with the upper and lower engaging portions 8a and 8b.

The above-mentioned building panel 1 can be manufactured, for example, through the following procedure. First, the stud 4 is joined to one side surface of the prepared face material 2 using an adhesive or the like. Next, the face material 2 is set on a mold having a concave portion corresponding to the shape of the foam material 3 to be formed, with the stud 4 facing downward. Then, a pressing force is applied to the molding die and the face material 2 from above and below by a pair of jigs.
In this state, after the starting material and the foaming material are injected into the internal space defined by the face material 2 and the mold, heat is applied to foam them. After the foam material 3 is sufficiently hardened by cooling, the face material 2 is removed from the mold. Then, on the face material 2,
A foam material 3 having a desired shape is formed, whereby the building panel 1 is completed.

Next, a method for constructing the building panel 1 according to the first embodiment will be described. FIG. 5 shows a state before the building panel 1 is assembled to the shaft set 11, and FIG. 6 shows a state where the building panel 1 is assembled to the shaft set 11. As shown in the figure, the foam material 3 of the building panel 1 created as described above
Into the installation space K surrounded by the columns 12 and the horizontal members 13. At this time, the engaging portions 8 formed on the horizontal members 13
The upper and lower positioning portions 7a, 7 of the building panel 1 are provided at a, 8b.
b is engaged. As a result, the building panel 1 is fitted while being guided, so that the center between the columns 12 constituting the frame 11 naturally coincides with the center of the foam material 3. As a result, the gap between the foam material 3 and the column 12 is kept within the range of the standard size (5 mm or less).

When the foam material 3 is fitted, the engaging portion 8
The positioning portions 7a and 7b slide with respect to a and 8b. However, the positioning portions 7a and 7b and the horizontal member 1
Since both Nos. 3 are made of wood, their friction coefficients are relatively small. For this reason, the positioning portions 7a, 7b are
Since the foam material 3 moves smoothly in the inside b, the foam material 3 is smoothly fitted. The installation of the building panel 1 fitted as described above is performed by driving a nail (not shown) or the like into the peripheral portion of the face material 2.

Further, the upper and lower end surfaces S3 and S5 and the left and right end surfaces S4 and S6 of the foam material 3 are formed with inclined surfaces 3b. Therefore, the area of the indoor side surface S <b> 2 of the foam material 3 is significantly smaller than the projected area of the installation space K in the frame 11. Therefore, when the foam material 3 is fitted, the indoor side surface S2 side of the foam material 3 smoothly enters the installation space K.

After the building panel 1 is attached, the pillar 1
2 is attached with an interior material (see FIG. 6) 15 of a wooden house.
Then, the indoor side surface S2 of the foam material 3 is pressed by the interior material 15, and the foam material 3 is deformed by plastic deformation of the foam material 3.
The indoor side surface S2 of the stud 4 is flush with the indoor side surface S12 of the stud 4. As a result, the indoor side surface S2 of the foam material 3 is pressed against the back surface of the interior material 15, no gap is formed between the interior material 15 and the foam material 3, and dew condensation occurs between the interior material 15 and the foam material 3. Will not occur.

At the same time, the inclined surface 3b is crushed and lost by the plastic deformation of the foam material 3. Therefore, there is no gap due to the inclined surface 3b between the end surfaces S3 to S6 of the foam material 3 and the columns 12 and the horizontal members 13 forming the frame 11. However, there is a slight gap (5 mm or less) within the standard range due to the vertical surface 3a. As a result, no dew condensation occurs between the foam material 3 and the columns 12 and the horizontal members 13. Then, after the interior material 15 is assembled, the exterior material (see FIG. 6) 16 of the wooden house is arranged so that the face material 2 cannot be seen from the outside of the wooden house, and the exterior material 16 is attached to the shaft assembly 11.
Attach to

Therefore, according to this embodiment, the following effects can be obtained. (1) A thin portion 5 is formed on the indoor side surface S2 of the foam material 3, and the thin portion 5 is formed at a position away from the stud 4. Then, between the thin portion 5 and the stud 4, a thick portion 6 in contact with the stud 4 is formed. For this reason, the foam material 3
And the stud 4 can be increased in bonding area. Therefore,
Even if the forming material (polystyrene) of the foam material 3 has poor adhesion to the stud 4, the foam material 3 can be prevented from peeling off from the stud 4.

(2) The thin portion 5 of the foam material 3 is formed not at the most part of the foam material 3 but at the portion farthest from the stud 4. Therefore, even if the forming material (polystyrene) of the foam material 3 is relatively weak, it is possible to prevent the strength of the entire building panel 1 from decreasing.

(3) Part of the foam material 3 corresponding to the indoor side of the wooden house is the indoor side surface S12 of the stud 4 corresponding to the indoor side.
And slightly overhang. Therefore, the foam material 3 is plastically deformed by attaching the interior material 15 in a state where the foam material 3 is attached to the frame 11. Due to this deformation, the indoor side surface S2 of the foam material 3 and the back surface of the interior material 15 can be pressed against each other. Therefore, the heat insulating effect can be reliably obtained, and the occurrence of dew condensation between the foam material 3 and the interior material 15 can be prevented.

(4) Since the material for forming the foam material 3 is made of polystyrene, the foam material 3 can be recycled. Therefore, there is no need for landfill disposal such as polyurethane, for example, and it is environmentally friendly.

(5) Since the expansion ratio of the foam material 3 is set to 30 to 70 times, the amount of the material (polystyrene) used can be kept within a suitable range, and the manufacturing cost of the building panel 1 can be reduced. The cost can be prevented from rising.
In addition, since the foaming ratio is set to an appropriate value, it is possible to prevent the strength of the foamed material 3 from decreasing while securing the heat insulating effect.

(6) A vertical surface 3a orthogonal to the outdoor side surface S1 of the foam material 3 is provided on the end surfaces S3 to S6 of the foam material 3.
And the indoor side surface S2 of the foam material 3 adjacent to the vertical surface 3a
An inclined surface 3b that is visible from the side is formed. For this reason, there is an advantage that the work of fitting the heat insulating wall panel 1 becomes relatively easy. At the same time, the positioning portions 7a and 7b of the building panel 1 can be easily fitted into the engaging portions 8a and 8b of the shaft assembly 11.

(7) Positioning portions 7 are provided at the upper and lower ends of the stud 4.
a, 7b are protruded, and the positioning portions 7a, 7b
Can be engaged with the engaging portions 8a and 8b provided on the shaft set 11 side. For this reason, it is possible to quickly and easily align the center of the building panel 1 accurately with the center between the columns 12 constituting the frame 11. Therefore, foam 3 and pillar 1
2 can be kept within the standard.

(8) By fitting the foam material 3 into the installation space K of the frame 11 and assembling the interior material 15 with the frame 11, the inclined surface 3b of the foam material 3 is eliminated. Therefore, since only the vertical portion 3a exists between the end surfaces S3 to S6 of the foam material 3 and the columns 12 and the horizontal members 13 forming the frame 11,
No large gap is formed by the inclined portion 3b. As a result, it is possible to prevent dew condensation from occurring between the foam material 3 and the columns 12 and the horizontal members 13.

(Second Embodiment) Next, a second embodiment of the present invention will be described focusing on parts different from the first embodiment.

In the second embodiment, the stud 4 is omitted as shown in FIG. In short, thin part 5
Are located at both ends of the foam material 3, and a thick portion 6 is formed between the thin portions 5. Therefore, in the second embodiment, substantially the same effects as in the first embodiment can be exerted. That is, the thin portion 5 of the foam material 3
Does not close most of the foam material 3. For this reason, even if the forming material (polystyrene) of the foam material 3 is relatively weak, it is possible to prevent the strength of the entire building panel 1 from decreasing.
