作業性の点で問題点が多々存在していた。
Conventionally, thermoplastic 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. things are used. These foams are installed by attaching them one by one during insulation construction, which requires a lot of time loss and construction costs.
There were many problems in terms of workability.
又、発泡体を一枚一枚取りつける為、発泡体間

場合も施工コストがかかり、作業性が劣るという
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.

Such a foam has a structure in which a flat thermoplastic resin foam having a plurality of hinge parts alternately provided on the upper and lower surfaces is folded alternately at each hinge part.

成を有するものである。 In addition, the present inventors have already proposed a thermoplastic resin foam for insulation construction that has good workability and strength as an improved version of the above-mentioned foam. Such a foam includes a plurality of hinge parts alternately provided 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. , which has a structure in which the laminate is alternately folded at each hinge portion.

The thermoplastic resin foam for insulation construction previously proposed by the present inventors has good workability in the former,
Although it is a good foam that does not cause any defects that impair its insulation effect, it has a structure in which the hinge portion is folded alternately, so there remains a problem with the strength of the hinge portion. That is, the thickness of the foam becomes thinner at the hinge part, and since the hinge part is bent, a load is inevitably placed on the hinge part, and there is a risk that cracks may occur in the hinge part when the hinge part is repeatedly bent.
又、後者においては、係る問題点を解消し、強

つた。 In addition, in the case of the latter, the problem has been solved, and although the foam is strong and has no defects such as cracks in the hinge part even after repeated bending, it is a film with many holes. Since it has a structure in which film-like materials are laminated, there are problems in terms of cost compared to the former, and there are also problems in terms of manufacturing cost, such as the need to provide a large number of holes in the film-like material during manufacturing. There was also a problem that made the manufacturing process complicated.

脂発泡体を提供することを目的とする。 The present invention overcomes these drawbacks and can be manufactured at a low cost and is easy to manufacture.It also has good workability when used, has high strength at the hinge part, and has a heat insulation effect. It is an object of the present invention to provide a thermoplastic resin foam for good heat insulation construction that does not cause any damaging defects.

Further, in the present invention, since the foam of the present invention is formed by folding a flat foam, the size of the foam of the present invention can be determined by defining the size of the flat foam. . When defining the size of the foam of the present invention based on the size of the flat foam, 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 are defined. In the present invention, taking the above-mentioned reasons into consideration, the length in the longitudinal direction of the flat plate-shaped foam is 0.9 to 36 m, the length in the width direction is 0.3 to 3 m,
Preferably, the length between each hinge part is 0.3 to 1.8 m, and the thickness is 0.1 to 5 cm.

In the present invention, the expansion ratio is 2 to 80 times, preferably 5 to 70 times, and the average cell diameter is preferably 0.05 to 2 mm. Further, as mentioned above, the thickness of the flat foam is preferably 0.1 to 5 cm; if it is too thin, the insulation effect will be poor;
If it is too thick, there is a risk that folding of the flat foam will be hindered, and the moisture permeability will be poor.

A hinge portion is formed at a predetermined location of the flat foam by pressing or hot pressing using a pressing jig, and then the foam is cut into a predetermined length to obtain a flat foam having the hinge portion. The foam of the present invention can be obtained by alternately folding the obtained flat foam at each hinge portion.

After that, by sequentially stretching and fixing the hinge portion 3, insulation construction can be easily carried out. 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.

に充填材を施すことも短時間で行える。 When performing insulation construction using the foam of the present invention, the foam of the present invention requires fewer alignments because each foam is large, and the number of seams between the foams is extremely small. As a result, gaps are less likely to be formed between the heat insulating plates, and deterioration of the heat insulating effect can be prevented as much as possible. Further, even if a gap occurs, since the amount of joints is small, filling material can be applied to the gap in a short time.

The strength of the hinge portion is increased, and even if the hinge portion is repeatedly bent, problems such as cracks will not occur in the hinge portion. In addition, since the film-like material is provided only at the hinge portion of the flat foam, the foam's good moisture permeability can be fully utilized, making it suitable for use in insulation construction in humid areas. I can do it. In addition, during manufacturing, the amount of film-like material used can be reduced,
Furthermore, since there is no need to make holes in the film, costs such as manufacturing costs and running costs can be saved, and the film can be manufactured easily.

As explained above, the foam of the present invention is a thermoplastic resin foam for heat insulation construction, which is made by folding a flat thermoplastic resin foam with a plurality of hinge parts alternately provided on the upper and lower surfaces at each hinge part. Since it is made by laminating a film-like material on at least one side of each hinge portion forming part of the above-mentioned flat thermoplastic resin foam, it has good workability, and there are no problems such as deterioration of the heat insulation effect. In addition to not causing damage such as cracks to the hinge portion even if the hinge portion is repeatedly bent, it also has various effects such as being easily manufactured at low cost.
