た。 In the case of the conventional heat-insulating building material B', as shown in Fig. 1, the core 2' is sealed with a pack film 1' made of stretched resin film to form the core material A'. The upper plate 3 and the lower plate 4 were joined. However, in such a conventional example, since the core 2' is simply sealed with the pack film 1' made of stretched resin film, the adhesive force between the core 2' and the pack film 1' is weak, and the upper plate 3 and the bottom Plate 4 is the second
There was a drawback that when the core 2' and the pack film 1' were pulled up and down as shown in the figure, they separated.

を接合して断熱建材Ｂを形成する。 The present invention will be explained in detail below with reference to Examples. Reference numeral 1 denotes a film for packs, and as shown in FIG. 3, a stretched resin film 1a made of polypropylene, polyethylene, polyvinyl chloride, etc., and a hot melt resin film 1b made of ethylene vinyl acetate copolymer, acrylic resin, polypropylene, nylon, etc. It is formed by laminating layers. 2 is roll core, honeycomb core,
A core such as a ring core, made of paper or synthetic resin. The core 2 is wrapped in the pack film 1 with the hot-melt resin film 1b inside, and is shrink-sealed under heat to form the core material A as shown in FIG. 4. When the core material A is formed in this way, the hot melt resin film 1
At b, the pack film 1 and the core 2 are welded together. An upper plate 3 and a lower plate 4 are joined to both upper and lower surfaces of this core material A to form a heat insulating building material B.

固に接合されて構造的に強固なものである。 As described above, the present invention is to seal the core with a pack film made by laminating a stretched resin film and a hot melt resin film so that the hot melt resin film of the pack film is on the inside, and heat the hot melt resin film and the core. Since the core material is formed by welding the two, the core and the pack film are firmly bonded using the hot melt resin film, and the top and bottom plates and the core material are firmly joined, resulting in a structurally strong structure. It is something.
