Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel which is arranged on a wall forming surface of a building and has an interior material on its back surface.

[0002]

BACKGROUND ART In some buildings such as unit houses, outer wall panels are used as outer walls. Such an outer wall panel is, for example, a composite panel in which an interior material is stretched on the back surface of the wall panel. The wall panel comprises, for example, an autoclave aerated concrete panel. The interior material is, for example, a gypsum board and a urethane board (or a styrene board) bonded together, and the urethane board side is adhered to the outer wall panel with an adhesive.

[0003]

Both sides, which are the bonding surfaces of the conventional wall panel and the interior material, are flat, and an adhesive is applied to such a plane to directly bond the wall panel and the interior material. In this case, since there is no escape area for the adhesive, uneven coating unevenness is likely to occur on the surface of the adhesive. When such coating unevenness occurs, the coating unevenness also affects the surface condition of the interior material, and the appearance of the interior material deteriorates. Therefore,
An object of the present invention is to provide a wall panel that can obtain a good appearance of an interior material regardless of how the adhesive is applied.

[0004]

A wall panel according to the present invention is a wall panel which is arranged on a wall forming surface of a building and has an interior material stretched on the back surface thereof, wherein an uneven portion is provided on the back surface, The portion is a stretched surface of the interior material, and the recess is an escape portion for the adhesive.

Materials for the interior material and the wall panel are arbitrary. The specific shape and arrangement of the uneven portion is also arbitrary,
For example, the convex portion or the concave portion may be formed continuously or discontinuously on the back surface of the wall panel. Further, in the case of the convex portion, the convex portion may be integrally formed with the wall panel, or the convex portion such as a T-bolt may be attached simultaneously with or after the molding of the wall panel.

[0006]

When the interior material is stretched on the wall panel according to the present invention, an adhesive is applied to the convex portion, and the interior material is pasted with the convex portion as a tension surface. When this interior material is attached to the convex portion, excess adhesive on the convex portion flows down to the concave portion which is a relief portion of the adhesive, and is necessary for bonding the wall panel and the interior material on the convex portion. Since only a small amount of the adhesive remains, uneven application of the adhesive is eliminated. As a result, regardless of how the adhesive is applied,
The interior material has a good appearance.

[0007]

EXAMPLE A wall panel 11 according to the present invention with reference to FIGS.
A first embodiment of will be described. Wall panel 11 according to the present embodiment
Is a back surface 13 on which the interior material 12 is stretched, on which linearly continuous projections 14 are formed at predetermined intervals. The convex portion 14 serves as a stretched surface of the interior material 12. And these adjacent protrusions
The spaces between 14 are formed into linearly continuous recesses 15, and these recesses 15 serve as escape portions for the adhesive 16. The wall panel 11 is arranged as an outer wall panel, for example, and is used as an interior material.
The 12th side is the inner wall.

These convex portions 14 are formed so as to be vertical when the wall panel 11 is placed on the wall forming surface of the building. The convex portion 14 may have a rectangular cross section, a trapezoidal shape, or the like, but the upper surface 17 is a flat surface parallel to the surface 18 of the wall panel 11. In addition, a plurality of holes 19 for facilitating the adhesion of the adhesive 16 are formed on the upper surface 17 at predetermined intervals.

The depth and width (that is, volume) of the recess 15
Need only be sufficient to receive the adhesive 16 that has flowed out of the convex portions 14. The wall panel 11 having the convex portions 14 and the concave portions 15 can be integrally molded by using a molding mold (not shown) when the material is, for example, autoclave curing aerated concrete.

For such a wall panel 11, an interior material 12
Can be set as follows: First, the wall panel 11 is arranged on the wall forming surface (for example, the outer wall forming surface) of a building such as a unit house, and the adhesive 16 is applied to each hole 19 of the upper surface 17 of the convex portion 14. The adhesive 16 is provided so as to protrude from the hole 19. Next, as shown in FIG. 1, the interior material 12 is pressed against the protrusions 14 to bond the interior material 12 to the protrusions 14. The interior material 12 is, for example, a composite material in which a gypsum board 21 and a urethane board 22 are bonded, and the urethane board 22 side serves as a bonding surface with the wall panel 11.

At the time of adhering the interior material 12, the adhesive 16 filled in the hole 19 overflows on the upper surface 17 as the interior material 12 is pressed, and excess adhesive 16 flows down into the recess 15. As a result, between the convex portion 14 of the wall panel 11 and the interior material 12, only the adhesive 16 in an amount necessary for bonding the two remains, and there is no extra adhesive 16 that causes uneven coating. . After this, by leaving it for a predetermined time, the adhesive 16 is cured and the interior material
12 is attached to the wall panel 11.

According to the wall panel 11 according to the above-described embodiment, when the interior material 12 is attached to the convex portion 14, the excess adhesive 16 on the convex portion 14 becomes the concave portion 15 which becomes the escape portion of the adhesive 16. Since it flows down to, only a small amount of the adhesive 16 necessary for bonding the wall panel 11 and the interior material 12 remains on the convex portion 14. Therefore, since there is no risk of uneven application due to a large amount of adhesive 16 and a small amount of adhesive 16, it is possible to stretch the interior material 12 in a planar manner.
A good appearance of the interior material 12 can be obtained.

The convex portion 14 and the concave portion 15 are formed by the wall panel 11
At the time of molding, since it can be integrally molded using a molding frame, the wall panel 11 according to the present embodiment can be easily manufactured. Furthermore, when the adhesive 16 is applied, it can be applied without considering unevenness of application, so the workability of applying the adhesive 16 is improved, and it is also useful for improving the construction efficiency.

Next, a second embodiment of the wall panel 31 according to the present invention will be described with reference to FIG. In the case of the wall panel 31 according to this embodiment, the convex portion includes the bolt 34 in which the shaft portion 33 is partially embedded in the back surface 32. The head 35 of this bolt 34 is flat. Further, a plurality of bolts 34 are provided in the vertical and horizontal directions at predetermined intervals. Then, the space between the plurality of bolts 34 becomes a recess 36 which is a relief portion of the adhesive 16.

Such bolts 34 can be provided, for example, by placing the slurry in a molding frame, arranging the bolts 34 at predetermined intervals in the slurry, and then hardening the concrete by autoclave curing or the like. . The interior material 12 can be stretched on such a wall panel 31 as follows. First, the wall panel 31 is arranged on the wall forming surface of a building such as a unit house, and the adhesive 16 is applied to the head 35 of the bolt 34.

Next, as in the first embodiment, the interior material 12 is pressed against the head 35 of the bolt 34 to bond the interior material 12 to the bolt 34. When bonding the interior material 12, the head
With respect to the adhesive 16 placed on the 35, the excess adhesive 16 flows down under the head 35 as the interior material 12 is pressed. As a result, between the bolts 34 of the wall panel 31 and the interior material 12, only an amount of the adhesive 16 necessary for adhering the two remains, and there is no extra adhesive 16 that causes uneven application.

After that, the adhesive 16 is cured by leaving it for a predetermined time, and the interior material 12 is attached to the wall panel through the bolts 34.
Sticked to 31. The wall panel 31 according to the above-described embodiment also provides the same effects as those of the first embodiment, such as a good appearance of the interior material 12.

In the first embodiment, the projection 14 is formed on the wall panel.
Although it is formed integrally with 11, the convex portion may be formed separately from the flat wall panel, and the convex portion may be provided by being bonded to this wall panel. Further, in the first embodiment, the hole portion 19 is formed on the upper surface 17 of the convex portion 14 for facilitating the adhesion of the adhesive agent 16. However, if the adhesive agent 16 having high viscosity is used, the hole portion 19 is It does not necessarily have to be formed.

Further, as the structure of the concave-convex portion, any structure other than the above-mentioned embodiment can be arbitrarily adopted. For example, on the back surface of a flat wall panel, a plurality of recesses of arbitrary shapes such as circles and squares are formed at appropriate intervals, and these recesses serve as escape areas for the adhesive, and the projections other than these recesses are provided internally. You may make it the tension surface of the material.
