とするものである。[Detailed Description of the Invention] The present invention relates to an improvement of a heat insulating material for concrete, and in particular, it is an object of the present invention to provide a heat insulating material for concrete that can discharge moisture or water vapor exuding or emanating from concrete to the outside.

るという問題を生ずるものであつた。 In order to impart waterproofness and heat resistance to conventional concrete substrates, such as concrete roofs,
A heat insulating layer made of plastic foam and a waterproof layer made of asphalt or the like are provided on the base surface. However, concrete bases usually contain humid water, and water vapor rising from indoors penetrates into the concrete base, and this moisture expands due to solar heat and becomes water vapor, which prevents it from escaping to the outside. However, it was blocked by the heat insulating layer and could not be discharged. Therefore, the water vapor pushes up the heat insulating layer and discharges through the gap formed between the heat insulating layer and the concrete surface, so the heat insulating layer becomes separated from the concrete base.
It was not possible to form sufficient heat insulation properties. Furthermore, if the water vapor contained in the concrete is not discharged to the outside and is allowed to cool overnight, it becomes water droplets that drip into the room, causing problems such as staining walls, tatami mats, etc.
これの改善するものとして、コンクリート基体

となる。 To improve this, when providing a heat insulating layer and a waterproof layer made of plastic foam on the concrete base surface, a heat insulating waterproofing method is provided in which grooves for moisture drainage are formed on both sides of the heat insulating layer, communicating from the center to the edges. The material is published as Utility Model No. 55-33363. However, when adhering this heat insulating layer to the concrete base surface and constructing a waterproof layer on top of it,
When compression processing is applied, the concave grooves are easily crushed and cannot perform a drainage function.

る。 In view of the current situation, the present invention has been made as a result of intensive research into improving this, and has resulted in the discovery of a heat insulating material for concrete that can easily discharge the moisture contained in the concrete base to the outside. That is, the present invention is characterized in that the heat insulating material provided on the concrete base surface is formed of two layers: a moisture permeable layer made of plastic nonwoven fabric and a heat insulating layer made of polyolefin foam having closed cells.

圧縮をうけるも、何等透水性を阻害することはな
い。 In particular, the present invention is to provide a moisture permeable layer made of plastic non-woven fabric in contact with the surface of the concrete base, and this moisture permeable layer prevents moisture contained within the concrete base from staying inside the base, allowing the moisture to flow through the non-woven fabric. It can be easily discharged to the outside through the process. Also, even though it is compressed during construction of a waterproof layer, it does not impede water permeability in any way.
なお不織布としては各種の合成樹脂製不織布が
使用できるが、好ましくはポリプロピレン製不織
布、ポリエチレン製不織布が使用される。 As the nonwoven fabric, various synthetic resin nonwoven fabrics can be used, but polypropylene nonwoven fabrics and polyethylene nonwoven fabrics are preferably used.

プロピレン発泡体が好ましい。 As the polyolefin foam forming the heat insulating layer in the present invention, polyethylene foam and polypropylene foam are particularly preferred.
