By the way, in recent years, the decrease of forest resources has been accelerated due to overcutting, and due to this, the deterioration of the global environment has become a major social problem. Therefore, the supply of timber is naturally small, and the price is rising accordingly. However, in each of the above wall panels, the face material made of wood such as plywood is used on both sides, and therefore the cost increase is inevitable, which is a major factor in increasing the manufacturing cost. Further, in the wall panel, since the face material is a load bearing material for a structure such as a house, a sufficient thickness is required, so that the wall panel as a whole becomes a heavy weight, and the site It has been a factor that impairs the workability of the construction at the time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wall panel in which the use of wood such as plywood is reduced and an installation structure thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. In FIG. 1, reference numeral 10 is a wall panel, and the wall panel 10 is a rectangular plate-shaped load bearing surface material 11 and rectangular plate-shaped heat insulating surface materials 12 and 1 attached to both surfaces thereof.
It consists of 2. As the bearing surface material 11, plywood, OSB (Oriented Strand Board), cement-based inorganic surface material, or the like is used. As the heat insulating surface material 12, foamed resin such as expanded polystyrene is preferably used. Further, regarding the attachment of the heat insulating surface material 12 to the load bearing surface material 11, adhesion with an adhesive is suitable.

To construct a wall using such a wall panel 10, first, as shown in FIG. 2, a pair of fixing members 13, 13 are arranged in parallel on a floor surface with a predetermined gap. These fixing members 13 and 13 are in the shape of an elongated rectangular column, and the width thereof is substantially the same as the thickness of the heat insulating face member 12. The gap between the fixing members 13 and 13 is substantially the same as the thickness of the load bearing surface member 11.

Next, the heat insulating panel 12, 12 of the wall panel 10
Each of the lower end portions is cut in the horizontal direction to separate the lower end portion from the load bearing surface material 11 to expose the lower end portion of the load bearing surface material 11. Here, the cut size of the heat insulating surface material 12 (the distance from the lower edge of the heat insulating surface material 12 to the cut line) is made substantially equal to the height of the fixing material 13. The heat insulating surface materials 12, 12 may be cut at the construction site or may be cut in advance at the factory.

Next, the exposed lower end portion of the load bearing surface material 11 of the wall panel 10 is inserted between the fixing materials 13 and 13 to fix the fixing material 1
The wall panel 10 is stood on 3 and 13. Then, screwing or nailing is performed from one fixing member 13 toward the other fixing member 13, thereby fixing the lower end portion of the load bearing surface member 11 in a state of being sandwiched between the fixing members 13 and 13.

Regarding the connection between the wall panels 10 and 10, after the wall panel 10 is fixed between the fixing members 13 and 13 by the above-mentioned procedure, as shown in FIG.
The joint end sides of the 10 heat insulating surface materials 12, 12 are cut. Next, a joint material 15 such as a plywood plate, a metal plate, a resin plate, or a heat insulating plate is attached to the cut portion 14, and this is fixed by fixing means such as nailing, screwing, or adhering, and as a result, the wall panel 10 10 are joined by interposing the joint material 16. Then, as shown in FIG.
The gypsum board 16 is attached from 2 to the fixing material 13, and the top is cross finished to construct a wall.

In such a wall panel 10, since the load bearing surface material 11 is used only in the central portion which becomes the core and the heat insulating surface materials 12 are used on both sides thereof, wood such as plywood is temporarily used. Since it is used only as a bearing surface material, the amount of wood used in the panel as a whole is reduced. Also, the heat insulating surface material 1
Since the foamed resin is used as 2, the load bearing surface material 11 is 1
The weight of the entire wall panel 10 is reduced due to the fact that the wall panel 10 is composed of one sheet.

In the above embodiment, the heat insulating surface material 12 is a rectangular plate having no hollow portion. However, when electric wiring or the like is required, a part of the heat insulating surface material 12 is cut out as appropriate. You may form a groove | channel and arrange | position wiring etc. in this. Also,
It is needless to say that the shape of the load bearing surface material is not limited to the rectangular plate shape shown in the drawings, and can be appropriately changed depending on the shape of the wall panel.

[0014]

As described above, in the wall panel according to the first aspect of the present invention, since the load bearing surface material is used in the central portion which becomes the core and the heat insulating surface material is used on both sides, the entire panel is In the case of seeing, the amount of wood used is reduced, and therefore the increase in manufacturing cost can be suppressed. Further, by using, for example, a foamed resin as the heat insulating surface material to be attached to both sides of the load bearing surface material, the weight of the entire wall panel is reduced in combination with the fact that the load bearing surface material is composed of one sheet, and therefore its transportation. It is possible to improve efficiency and workability during on-site construction.

In the wall panel installation structure according to a second aspect of the present invention, the heat insulating surface material is cut at a construction site or precut in a factory or the like, and the lower end portion of the exposed load bearing surface material is sandwiched between fixing materials. Furthermore, since it can be obtained only by fixing it to the machine with screws or nails, the installation structure is extremely easy and has excellent workability. In the wall panel installation structure according to claim 3, since the fixing material and the heat insulating surface material are finished by being covered with the same gypsum board, the joint portion in the installation portion of the wall panel is completely invisible from the outside. Therefore, the subsequent cloth finishing or the like becomes easy.
