A self-adhesive foam heat insulating material such as phenolic resin foam or polyurethane foam is foam-filled between a pair of hard surface plates made of, for example, thin metal plates or fiber-reinforced plastic (FRP) thin plates. It is used for prefabricated refrigerators, storage rooms, etc., and for partitions that require insulation. In addition, in order to further improve the heat insulation properties, a heat insulating layer made of breathable fibrous material such as nonwoven fabric or glass wool fiber impregnated with a heat insulating material is laminated between the surface plate and the foam heat insulating material. Sand Germanch panels are known (Japanese Unexamined Patent Publications No. 118852/1985, No. 56914/1983, and Japanese Patent Unexamined Patent Application No. 60/1983).

Assembling and disassembling mold means such as plywood and holding means c, and setting surface plates b, b and frame material a, etc., must be carried out separately, which requires a large number of man-hours.
There was also the problem that automation had its limits. In addition, in the latter case, that is, in the continuous foaming method shown in Fig. 9, productivity can be improved, but there is a risk that the supply of the breathable thin layer will be uneven, and there is a problem that the insulation performance will deteriorate. . Furthermore, there is a problem that not only the cut portions of the panel j become irregular, but also rust occurs at the cut edges. In addition, there is a risk that the cut edges may be damaged during transportation, and when constructing a structure, the cut edges require foaming on site between the panels and other panels, so there are many problems in construction. This requires a lot of effort and time, and causes a decrease in fitting accuracy.

Then, the upper and lower surface plate groups 54 and 56 are continuously supplied to the heat insulating material injection part 62, and the thin layer body 12 is sequentially placed on the upper inner surface of each surface plate 10 of the lower surface plate group 56. The heat insulating material is supplied to the heat insulating material injection part 62, and both surface plates 10, 1 are supplied from the heat insulating material supply nozzle 46.
A heat insulating material 14 is injected between the spaces 0 and 7.
After foaming and filling by heating at a temperature of about 60° C. to form a heat insulating sandwich panel body 48, the adhesive tape 52 is cut with a saw 72 to form a heat insulating sand beach panel. In this case, the heat insulating material supply nozzle 46 is configured to be able to supply the heat insulating material 14 while swinging left and right and retreating as necessary. Further, the surface plate 10 is formed with bent pieces 16, 16, . , 24 may also be supplied.
なお、上記実施例の製造方法では、下側表面板

２を添設する場合について説明したが、この際、
上側表面板群５４の下方側内面にも同様に薄層体
１２を添設することも可能である。 In the manufacturing method of the above embodiment, the thin layer body 1 is formed only on the upper inner surface of the surface plate 10 of the lower surface plate group 56.
We explained the case where 2 is attached, but in this case,
It is also possible to attach the thin layer body 12 to the lower inner surface of the upper surface plate group 54 as well.

で、以下のような効果が得られる。[Effects of the Invention] As described above, according to the method for manufacturing a heat insulating sanderch panel of the present invention, a plurality of hard surface plates each having right-angled bent pieces formed at least on opposite sides of the periphery are prepared. Then, a pair of surface plates, in which these hard surface plates are connected in the longitudinal direction by adhesive means so that they are on the same plane and adjacent to each other in the front and rear edges, are continuously supplied so as to be close to each other and face each other. At the same time, an air permeable thin layer body cut in advance to a size that is attached to the entire inner surface of the hard surface plate is continuously supplied and attached to the inner surface of at least one of the hard surface plates of the surface plate group. After continuously injecting and foaming the foamable organic heat insulating material that impregnates and permeates the air permeable thin layer between the face plates, the connection by the adhesive means is cut, so that the following effects can be obtained.
(1) 断熱性能が高くかつ寸法精度の高い断熱サン
