Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel, and particularly to an outer wall and an inner wall of a building unit such as a house.

[0002]

BACKGROUND ART A building unit such as a house is composed of four columns at four corners and a frame composed of a ceiling beam and a floor beam connecting the upper and lower ends of these columns to an outer wall, an inner wall, a ceiling material, a floor material, etc. It is configured by attaching. By the way, it is convenient if various fittings inside the building unit, such as finishing the inner wall, can be done by pasting cloth cloth or vinyl cloth directly on the inner surface of the outer wall, but from the problems of the finishing accuracy of the inner surface of the outer wall and the mounting accuracy of the outer wall. , But good results have not always been obtained. Therefore, the outer wall and the like are attached as shown in FIG.

That is, conventionally, the outer wall 30 and the inner wall 31 are manufactured as separate bodies, the outer wall 30 is attached to a ceiling beam and a floor beam, and the inner wall 31 formed of a wooden panel frame 32 is attached to the inside thereof. A heat insulating material 33 is packed in the wooden panel frame 32, and a gypsum board 34 is attached to an indoor surface of the wooden panel frame 32.

When a building is to have a fireproof structure, the outer wall
Fireproof joint material 36 is packed in the joint C between the 30 pieces,
Furthermore, backup material 37 is packed, and finally caulking
38 are packed.

[0005]

However, in mounting the outer wall 30 and the like as described above, the outer wall 30 and the inner wall 31 are manufactured as separate bodies, and the inner wall 31 is mounted after the outer wall 30 is mounted. However, there is a problem that the workability is poor because the manufacturing and mounting are troublesome twice. Also, the wooden panel frame 32 that constitutes the inner wall 31 must be created,
Since the heat insulating material 33 has to be packed in the panel frame 32, there is a problem that the panel frame 32 is complicated to manufacture and the material cost increases.

Further, as for the fireproof structure, the work C is complicated because the joint C of the outer wall 30 must be filled with the fireproof joint material 36 at the site.

It is an object of the present invention to provide a wall panel which is easy to manufacture, has improved workability in mounting, and has excellent fire resistance, and which serves as an outer wall and an inner wall.

[0008]

Therefore, a first aspect of the present invention is a wall panel used in a building, wherein a gypsum board is integrally provided on the back surface of PALC (lightweight cellular concrete) through a foamed plastic member. It is a wall panel.

A second aspect of the invention is a wall panel provided with a refractory material on the surface of the foamed plastic member and in the vicinity of the joint portion of the PALC.

[0010]

According to the present invention as described above, the foamed plastic member is fixed to the back surface of the PALC, and the gypsum board is attached to the back surface of the foamed plastic member to form an integrated wall panel. Here, a refractory material may be provided on the surface of the foamed plastic member and in the vicinity of the joint portion of the PALC.

Since the gypsum board which is the inner wall is attached to the back surface of the PALC which is the outer wall via the foamed plastic member and these are integrally formed, it is not necessary to separately arrange the outer wall and the inner wall. Therefore, it is easy to manufacture and the workability of mounting is also easy. In addition, the panel frame for the inner wall is not required, the labor for manufacturing the same is not required, and the material cost is low, thereby achieving the above object. Further, if a fire resistant material is provided on the surface of the foamed plastic member that contacts the back surface of the outer wall material, the wall panel will have excellent fire resistance.
