It is common practice to place building panels.

As shown in FIGS. 4 and 5, this type of architectural panel 51 is provided with a face member 52 constituting an outer surface thereof. A foam material 53 having a heat insulating function is joined to the indoor side surface of the face material 52. In addition, a single stud 54 extending along the panel longitudinal direction is joined to a central portion of the face member 52 on the side where the foam material 53 is provided. Both ends of the stud 54 are the same as the end surfaces of the foam material 53 without protruding outward from both end edges of the foam material 53. And the building panel 51 is composed of a pillar 56 of the house and a horizontal member 57.
It is assembled by fitting it into the installation space surrounded by.

By the way, the width of the foam material 53 is set to
When the space is formed to be substantially the same, the foam material 53 and the column 56 rub against each other when the building panel 51 is fitted into the installation space. As described above, since the materials for forming the foam material 53 and the columns 56 are different from each other, the friction coefficients of the two are high. Therefore, the building panel 51 cannot be fitted smoothly.

Therefore, in order to make it easy to fit the architectural panel 51, the projected area of the architectural panel 51 is made slightly smaller than the projected area of the installation space. However, in a state where the architectural panel 51 is fitted in the installation space,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the building panel of the present invention is used for a building panel for a wooden house, for example, a ceiling will be described below with reference to the drawings.

FIG. 1 is a front view of the building panel 1 viewed from the indoor side of a wooden house, FIG. 2 is a plan sectional view of the building panel 1, and FIG. 3 is a view before the building panel 1 is fitted. It is sectional drawing which shows a state. As shown in FIGS. 1 to 3, the building panel 1 is basically configured by a foam material 3, a stud 4 and the like made of polystyrene.

The foam material 3 is, as it were, one stud 4,
It is in a state of being divided into two along the panel longitudinal direction. 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 foam material 3 is inserted into the installation space surrounded by the columns 12 constituting the frame 11 of the wooden house and the horizontal members 13 such as beams and bases. It has become. 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 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 building panel 1. The surface corresponding to the indoor side of the thin portion 5 and the surfaces corresponding to the left and right end surfaces S4 and S6 of the foam material 3 are open. In this embodiment, the ratio of the width of the thin portion 5 to the width of the foam material 3 is 10
It is set to ~ 80%.

In the foam material 3, a portion other than the thin portion 5 is a thick portion 6 which is 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 of the stud 4. Then, when the building panel 1 is fitted in the installation space K of the frame 11, the indoor side surface S <b> 2 of the foam material 3 is disposed 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 3 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.

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 hard urethane foam, a phenol resin, a silicone resin, a urea resin, 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. Further, when the expansion ratio is higher than 70 times, there is an advantage that the thermal conductivity increases as the number of bubbles increases. However, this is because the strength of the entire foam material 3 is reduced. The expansion ratio of the foam material 3 is 35 to 65.
It is preferable to increase the ratio by a factor of two, and it is even more preferable that the ratio be within the range of 40 to 60 times.

As shown in FIG. 1, a pair of positioning portions 7a and 7b are provided at both 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. In this embodiment, the protrusion amount of the positioning portions 7a and 7b is set to 0.5 cm to 10 cm, and more preferably, to 1 to 3 cm. The positioning portion 7 a is provided on the center line of the foam material 3. The positioning portions 7a and 7b are made of the same material (wooden) as the horizontal member 13 forming the shaft set 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 respectively engaged with the upper and lower engaging portions 8a and 8b in an uneven relationship.

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
The foam material 3 moves smoothly in the inside b, and the foam material 3 is smoothly fitted.

Further, inclined surfaces 3b are formed on the upper and lower end surfaces S3, S5 and the left and right end surfaces S4, S6 of the foam material 3. 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
Attach wooden house interior materials to 2. Then, foam material 3
Is pressed down by the interior material, and the plastic side deformation of the foam material 3 makes the indoor side surface S2 of the foam material 3 flush with the indoor side surface S12 of the stud 4. As a result, the foam material 3
The indoor side surface S2 is pressed against the back surface of the interior material, no gap is formed between the interior material and the foam material 3, and no dew condensation occurs between the interior material and the foam material 3.

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.

Therefore, according to this embodiment, the following effects can be obtained. (1) Positioning portions 7a, 7b are protrudingly provided at the upper and lower ends of the stud 4, and the positioning portions 7a, 7b can be engaged with the engaging portions 8a, 8b provided on the shaft assembly 11 side. ing. 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, the gap between the foam material 3 and the pillar 12 can be kept within the standard.

(2) Positioning parts 7a, 7b and engaging part 8
a and 8b are engaged in an uneven relationship. Therefore,
Since the positioning portions 7a and 7b can be easily engaged with the engaging portions 8a and 8b, the building panel 1 can be quickly assembled to the shaft assembly 11.

(3) Positioning parts 7a, 7b and engaging part 8
a and 8b are provided in plurality above and below the stud 4 respectively. Therefore, it becomes possible to align the center of the building panel 1 more accurately.

(4) A thin portion 5 is formed on the indoor side surface S 2 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 bonding area between the foam material 3 and the stud 4 can be increased. Therefore, the forming material (polystyrene) of the foam material 3 is
Even if the adhesiveness to the stud 4 is poor, it is possible to prevent the foam material 3 from peeling off from the stud 4.

(5) The thin portion 5 of the foam material 3 does not occupy most of the foam material 3 but is formed at a 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.

(6) 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.
Slightly overhanging. Therefore, the foam material 3 is plastically deformed by attaching the interior material while being attached to the frame 11. Due to this deformation, the indoor side surface S2 of the foam material 3 can be pressed against the back surface of the interior material. Therefore, the heat insulating effect can be reliably obtained, and the occurrence of dew condensation between the foam material 3 and the interior material can be prevented.

(7) 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.

(8) 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.

(9) 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 building panel 1 is 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.

(10) The foam material 3 is placed in the installation space K of the
The inclined surface 3b of the foam material 3 is eliminated by fitting into the frame member 11 and assembling the interior material. Therefore, since only the vertical surface 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 surface 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.
