Conventionally, thermoplastic synthetic resin foams such as polystyrene resin have been used for insulation construction of houses, buildings, etc., and these are cut into rectangular shapes with a certain area, such as 0.91 m long and 0.91 m wide. are used. These foams are installed by attaching them one by one during insulation construction, which causes a lot of time loss and has many problems in terms of construction cost and workability.

問題が生じる。 Furthermore, since the foams are attached one by one, misalignment occurs between the foams, and this misalignment causes gaps between the foams, resulting in a reduction in the heat insulation effect. In order to eliminate such problems, for example, filling material is applied between the foam bodies, but this also causes problems such as high construction costs and poor workability.

The thermoplastic resin foam for insulation construction previously proposed by the present inventors has good workability and is a good foam that does not cause any defects that impair the insulation effect. Since it has a structure that can be folded up, there remained a problem with the strength of the hinge part. That is, the wall pressure of the foam becomes thinner at the hinge part, and the bending inevitably places a load on the hinge part, which poses problems such as the risk of cracks occurring in the hinge part if it is repeatedly bent.

Further, in the present invention, since the foam of the present invention is formed by folding a laminate, the size of the foam of the present invention can be determined by defining the size of the laminate.
When defining the size of the foam of the present invention based on the size of the laminate, it is necessary to define the length in the longitudinal direction, the length in the width direction, the length between each hinge part, and the thickness of the flat foam. However, in the present invention, in consideration of the above reasons, the length in the longitudinal direction of the laminate is 0.9 to 36 m, the length in the width direction is 0.3 to 3 m, and the length between each hinge part is
The length is preferably 0.3 to 1.8 m. In addition, as for the thickness of the laminate, the thickness of the flat foam is 0.1 to 5 cm,

によりヒンジ部を形成することもできる。 Further, hinge portions can also be formed at predetermined locations on the flat foamed material before the film material is laminated thereon by cutting with a knife, heat melting, or pressing with a pressing jig or the like.

もできる。 When using the foam of the present invention constructed as described above, for example, as shown in FIG. Thereafter, by sequentially extending and fixing the hinge portion 5, insulation construction can be easily performed. Alternatively, it is also possible to fix the extended ends of the foam of the present invention at the upper part of the area to be heat-insulated, and then gradually move downward and fix the foam.

填材を施すことも短時間で行える。 When insulation construction is performed using the foam of the present invention, the foam of the present invention has a large size, so the number of alignments is reduced, and the number of seams between the foams is extremely small. As a result, there are fewer gaps between the heat insulating plates, and a reduction in the heat insulating effect can be prevented as much as possible. Furthermore, even if a gap occurs, since the amount of joints is small, filling material can be applied to the gap in a short time.

行に好適に使用することができる。 In addition, since a film-like material is provided on at least one side of the flat foam, the strength of the foam itself is improved, and the strength of the hinge portion is also increased, so that even if the hinge portion is repeatedly bent, the hinge There will be no problems such as cracks in the parts. In addition, since the film-like material has many holes, it is possible to prevent the moisture permeability of the foam from decreasing due to lamination of the film-like material, and it can be suitably used for heat insulation in humid regions.

As explained above, the foam of the present invention has a plurality of holes on the upper and lower surfaces of a laminate consisting of a flat thermoplastic resin foam and a film-like material provided on at least one side of the foam and provided with a large number of holes. Since the hinge parts are provided alternately and the laminate is folded alternately at each hinge, it is easy to work when used for insulation construction, and does not cause a decrease in insulation properties. In addition, it has a high strength and has various effects such as no problems such as cracks in the hinge portion even after repeated bending, and no deterioration in moisture permeability.
