Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing an inner wall panel, and can be applied to, for example, an inner wall panel of a unit building.

[0002]

BACKGROUND ART In recent years, as a building such as a house, a prefabricated building including a box-shaped unit or the like has been built. For example, as shown in FIGS. 3 and 4, a building unit 51 of a unit building is configured by attaching an outer wall panel 56 to a unit frame 55 assembled in a box shape with an upper beam 52, a lower beam 53 and a pillar 54. . Inside the building unit 51, a ceiling panel 57 is stretched over the upper beam 52 and a floor panel 58 is stretched over the lower beam 53. An inner wall panel 59 is provided along the outer wall panel 56 between the ceiling panel 57 and the floor panel 58.

Conventionally, in the construction of the building unit 51, such an inner wall panel 59 is provided as follows, for example. First, the positioning material 61 is fixed to the ceiling panel 57 and the floor panel 58 by nailing or bonding. Next, the core member 62 is fixed to each positioning member 61, and the inner wall panel 59 is fixed to these core members 62. Alternatively, the core member 62 and the inner wall panel 59 may be integrally fixed to the positioning member 61.

[0004]

According to the above-mentioned conventional method of constructing the inner wall panel 59, even if the inner wall panel 59 is brought close to the outer wall panel 56 to make a large space in the building unit 51, the outer wall panel 56 and the inner wall panel 56 are not provided. Positioning material between 59
Since the 61 is interposed, the position of the inner wall panel 59 is limited by the positioning member 61. Therefore, an object of the present invention is to provide a method for constructing an inner wall panel that can provide an inner wall panel without interposing a positioning member, and thereby can take a large space in a building.

[0005]

According to the method of constructing an inner wall panel of the present invention, an uneven portion is formed on the back surface of an outer wall panel of a building, and the core material of the inner wall panel is locked to the uneven portion. Characterize. The core material may be locked to the uneven portion as long as at least a part of the core material is in contact with the uneven portion.

The shape of the concavo-convex portion may be continuous or discontinuous. Also, the method of forming the uneven portion is arbitrary, and for example, when molding the outer wall panel, it may be formed by using a mold material for molding the uneven portion, or a separate convex portion on the already molded outer wall panel. May be fixedly formed.

When the uneven portion is formed by using a mold material,
It may be formed by laying a mold material on the inner bottom surface of the molding frame and then pouring the slurry into the mold, or after pouring the slurry into the mold frame, when the mold material is slightly hardened, the mold material is poured from above the slurry. You may make it press and form. When pressing the mold material from above the slurry to form the irregularities, the core material of the inner wall panel may be used, or a member corresponding to the shape of the core material may be used.

[0008]

In the construction method of the inner wall panel according to the present invention,
The core material of the inner wall panel is directly engaged with the uneven portion on the back surface of the outer wall panel. Therefore, it is not necessary to provide a positioning member for the core material as in the prior art. This makes it possible to make the inner wall panel closer to the outer wall panel and save a large space in the building by the amount that the positioning member is unnecessary.

[0009]

EXAMPLE A method of constructing an inner wall panel according to an example of the present invention will be described with reference to FIGS. First, as shown in FIG. 1, an outer wall panel 11 used in this embodiment has a plurality of protrusions 13 formed on its back surface 12, and the core of the inner wall panel 14 extends along these protrusions 13. The material 15 is locked. The outer wall panel 11 is for a unit house, for example.

The projections 13 have a rectangular prism shape and are arranged vertically and horizontally at a predetermined interval. Convex parts adjacent to each other in the lateral direction
The predetermined space between the cores 13 is substantially equal to the width of the core material 15 so that the core material 15 is fitted between the convex portions 13. These ridges
The reference numeral 13 is formed integrally with the outer wall panel 11. On the other hand, the back surface 12 portion where these convex portions 13 are not formed is
It becomes the concave portion 16 of the present embodiment.

The outer wall panel 11 as described above can be manufactured, for example, as follows. First, a mold material for forming the convex portions 13 is laid in a molding frame (not shown), and the lightweight cellular concrete slurry is poured into the frame. next,
After the slurry is temporarily cured to form a panel, the panel is demolded, placed in an autoclave, and subjected to high temperature and high pressure curing. As a result, the outer wall panel 11 integrally formed with the protrusion 13 is obtained.

The core material 15 is locked to the outer wall panel 11 so as to abut on the side surface portions 17 of the respective convex portions 13 which are laterally adjacent to each other and also on the concave portion 16 of the rear surface 12. If the core material 15 is not held between the protrusions 13 during this locking, the core material 15 may be fixed to the outer wall panel 11 by hitting, bonding, or the like. Then, the vertical core material 15 has a predetermined interval (for example, a convex portion).
A plurality of 13 are arranged at a distance of 3 or 4). In addition, the horizontal core material 15 corresponds to these vertical core materials 15.
A plurality of them are arranged in the same manner as the vertical core material 15.
In the case of these core materials 15, they are in contact with the upper surface portion 18 of the convex portion 16 and also in contact with the concave portion 16 of the rear surface 12 and are locked to the outer wall panel 11.

The inner wall panel 14 is constructed as follows using the outer wall panel 11 as described above. The building according to this embodiment is a unit house. That is, as shown in FIG. 2, first, in manufacturing the housing unit 21 in the factory, the pillar 2
2. Make a unit frame 24 assembled with beams and the like. On the other hand, as described above, the uneven portions 13, 16 of the outer wall panel 11
The core material 15 is prepared in the vertical and horizontal directions.

Next, the floor material 2 is placed inside the unit frame 24.
5, an outer wall panel 11 to which a ceiling material (not shown) or the like is attached, and the core material 15 is locked to the outer side, and an outer wall panel of a corner portion
Install 19. Next, the inner wall panel 14 is fixed so as to come into contact with the core material 15 of the outer wall panel 11. The inner wall panel 14 may be fixed directly to the core material 15 by fixing or by adhering, or may be fixed to the floor material 25 by fixing. When the corner portion 26 of the pillar 22 is provided so as to project, an appropriate interior material 27 is stretched along the corner portion 26.

According to the method of constructing the inner wall panel 14 according to the above embodiment, the core material 15 of the inner wall panel 14 is the back surface of the outer wall panel 11.
The conventional positioning member 61 (see FIGS. 3 and 4) for the core member 15 is unnecessary because it is directly engaged with the uneven portions 13 and 16 of the twelve. Therefore, since the positioning member 61 is unnecessary, the inner wall panel 14 can be brought closer to the outer wall panel 11 and a large space can be secured in the housing unit 21.

Further, since the uneven portions 13 and 16 of the outer wall panel 11 can be formed at the same time when the outer wall panel 11 is manufactured by laying a mold material for forming the raised portion 13 in the mold, the outer wall panel 11 of the present embodiment. Is easily obtained. Furthermore, conventional positioning material 61
Since the installation work of is not required, the manufacturing of the housing unit 21 can be simplified.

In the above-described embodiment, when the uneven portions 13 and 16 are formed on the outer wall panel 11, a mold material for forming the convex portions 13 is laid in the mold and the slurry is poured into the mold. However, it is also possible to form the mold by pressing the mold from above the slurry when the slurry poured into the mold is slightly hardened without laying the mold. The mold material in this case is the inner wall panel 14
The core material 15 may be used, or a member corresponding to the shape of the core material 15 may be used. Further, although the outer wall panel 11 and the inner wall panel 14 of the above-described embodiment are for unit houses, the present invention can be applied to buildings other than unit houses in the same manner.
