しかし乍ら、これらを切断するためには鋸やカッターを
必要とするため、防水層を傷つけ易く、また一般に断熱
材として用いられる発泡合成樹脂との間の熱膨張率及び
収縮率に大きな差があるため、施工後に防水層に亀裂を
生じ、防水性能を損なう場合がある。However, since a saw or a cutter is required to cut them, it is easy to damage the waterproof layer, and there is a large difference in the coefficient of thermal expansion and contraction with the foamed synthetic resin generally used as a heat insulating material. Therefore, the waterproof layer may be cracked after the construction, and the waterproof performance may be impaired.
本考案はかかる実情に鑑み上記問題点を解消すべく鋭意
研究の結果、本考案に到達したものである。The present invention has arrived at the present invention as a result of earnest research to solve the above problems in view of the above circumstances.
本考案の実施例を示す図面に基づいて説明すると、第１

設けられている。A first embodiment of the present invention will be described with reference to the drawings.
In the figure, the corner material of the present invention has a triangular cross section (1
It is composed of a rod-shaped body (2) of a heat-resistant polystyrene-based resin foam molding having a), and cuts (3) are provided at appropriate intervals.
耐熱性ポリスチレン系樹脂としては、例えばアルファメ

に起因するクラック等のトラブルがより効果的に防止さ
れ、好都合である。The heat-resistant polystyrene-based resin is, for example, "Heatmax foam" obtained by copolymerizing alpha methyl styrene.
HS ”(registered trademark, manufactured by Kanegafuchi Chemical Industry Co., Ltd.), or styrene resin foam extruded polystyrene foam in which maleic acid is copolymerized. Further, when the same or similar type of foamed synthetic resin as the heat insulating material is used, the thermal expansion / shrinkage ratio becomes the same or similar, and troubles such as cracks caused by the difference in thermal expansion / shrinkage ratio are more effectively Prevented and convenient.
断面を形成する三角形は、通常は直角三角形である。本
考案のコーナー材は押出成形により容易に製造される。The triangles forming the cross section are usually right triangles. The corner material of the present invention is easily manufactured by extrusion molding.
切込み（３）は、適当間隔毎に手で折り曲げることによ
り切断できる程度の切込みで、該切込み（３）はコーナ
ー材の１面、２面又は３面即ち全面に設けることができ
る。The cuts (3) are cuts that can be cut by manually bending at appropriate intervals, and the cuts (3) can be provided on one side, two sides or three sides of the corner material, that is, the entire surface.

ト（８）が打設されている。Fig. 3 shows what is called an exposure prevention heat insulation construction method. A heat insulating material (5) is laid on a concrete slab (4), and the wall (4a) of the concrete slab (4) and the heat insulating material (5) are The corner material (6a) of the present invention is brought into contact with the corner portion, and the waterproof layer (7) is provided thereon. On the other hand, Fig. 4 shows what is called a concrete pressing method. After the corner material (6b) of the present invention is brought into contact with the corner of the concrete slab (4) and its wall (4a), the waterproof layer (7) is provided, a heat insulating material (5) is laid on it, and concrete (8) is poured on it.

間に熱膨張・収縮率の大きな差がなく、施工後における
膨張や収縮による防水層のクラック等が防止される。As mentioned above, since the corner material of the present invention is made of foamed synthetic resin and has pre-cuts, it can be easily cut by hand without the need for a tool such as a saw or a cutter.
These tools do not damage the waterproof layer and greatly improve workability. Also, because it is made of heat-resistant polystyrene resin, there is no big difference in thermal expansion / contraction ratio between the heat insulating material (foam synthetic resin) and the corner material, and cracks etc. of the waterproof layer due to expansion and contraction after construction are prevented. .
