Foaming resin. A second face material is arranged on the other side of the panel outer peripheral frame via an intermediate rail, and an air layer is formed between the second face material and the foamed resin. According to the wall panel having this configuration, a heat insulating effect can be obtained by the foamed resin filled therein. In this case, since the foamed resin is filled and foamed between the panel outer peripheral frame and the first face material, it can be filled without gaps, and excellent heat insulating properties can be obtained. Also, due to the adhesive force of the foamed resin, the panel outer peripheral frame,
The foamed resin and the first face material are joined. Therefore, the first face material can be joined without using a joining member such as a screw or a nail, and the reinforcing crosspiece can be omitted due to the strength of the foamed resin. For these reasons, a wall panel excellent in heat insulation can be easily manufactured with a simple configuration having a small number of parts and a small number of work steps. On the other hand, since an air layer is formed between the foamed resin and the second face material, excellent sound insulation properties can be obtained.

This wall panel can be applied to an outer wall panel, in which case the first panel is an exterior panel and the second panel is an interior panel panel. As described above, when applied to the outer wall panel, by using the first face material joined with the foamed resin as the exterior face material, a fixing tool such as a screw is exposed on the exterior face material exposed to the weather. No need for waterproofing the screw head. Also,
By applying a finish paint or a tile to the first face material in advance at a factory or the like, it is possible to omit the process of painting the outer surface of the wall panel at the site. The surface of the foamed resin exposed to the air layer is preferably covered with a moisture-proof sheet. As a result, the moisture that has entered the air layer is prevented from entering the foamed resin, and the deterioration of the foamed resin is prevented. It is preferable that each of the middle rails extends in the vertical direction, and upper and lower ends thereof are fixed to a panel outer peripheral frame by a fixing tool, and that the upper and lower ends of the air layer are open. By setting the upper and lower ends of the air layer to be in an open state, comfortable livability can be obtained by ventilation in the wall.

The wall panel 1 is a non-bearing outer wall panel, the first panel 3 is an exterior panel, and the second panel 4 is an interior base panel. The facing material 3 for the exterior is preferably an inorganic board. The face material 4 for the interior base may be plywood or the like. Here, the first face material 3 for the exterior uses a gypsum board pre-coated product, and the second face material 4 for the interior base uses an unpainted gypsum board. The foaming resin 5 is foamed in a mold (not shown) while maintaining a predetermined interval between the panel outer peripheral frame 1 and the first face material 3 so that the adhesive strength (adhesive strength 1) of the foaming resin 5 is maintained. 0.5 to 2.0 t / m ²
To the extent that they are integrally joined together.

The moisture-proof sheet 8 has a pressure-sensitive adhesive layer on the back surface, and is adhered to the foamed resin 5 and the surface of the panel outer frame 1 by its adhesiveness. Each of the middle bars 6 comprises a wooden bar, and extends in the vertical direction, and a plurality of the bars are provided at intervals. Each of the middle rails 6 is disposed on the front side of the moisture-proof sheet 8, and upper and lower ends thereof are joined to the panel outer peripheral frame 1 by fixing tools (not shown) such as tapping screws. 2nd face material 4 for interior

Further, since the panel outer peripheral frame 1, the foamed resin 5, and the first face material 3 are joined by the adhesive force of the foamed resin 5, each member can be joined without using a joining member such as a screw or a nail. In addition, since the foamed resin 5 is filled without gaps, a reinforcing crosspiece can be omitted with the strength of the foamed resin 5. For these reasons, a wall panel excellent in heat insulation can be easily manufactured with a simple configuration having a small number of parts and a small number of work steps. The middle crosspiece 6 is used on the side of the second face material 4, but since the middle crosspiece 6 serves as a base for only the interior face material 4, only a thin member is required, and firm joining is also possible. It is not required and can be easily installed. Since the upper and lower ends of the air layer 7 in the wall panel 1 are open, the upper and lower opening portions have a building structure that opens from the eaves or the base to the outside or the underfloor space. Comfortable habitability is obtained. Since the surface of the foamed resin 5 exposed to the air layer 7 is covered with the moisture-proof sheet 8, moisture entering the air layer 7 is prevented from entering the foamed resin 5, and the deterioration of the foamed resin 5 is prevented. .
