スチレンの悪臭発生等により作業上問題がある。また、
下地との接着力が強いので下地の伸縮により発生する亀
裂応力に追従し難く防水層の破断を起こす懸念がある。(Conventional technology and issues) The hand-lay construction method of FRP waterproof layer that has been used conventionally is 2.
The coating requires ~5 layers, which is time-consuming, and there are problems in terms of work, especially due to the generation of a bad odor from the styrene component. Also,
Since the adhesive force with the base is strong, it is difficult to follow the cracking stress generated by expansion and contraction of the base, and there is a concern that the waterproof layer may break.

きることを見出した。(Means for Solving the Problems) As a result of intensive research to solve the above-mentioned problems, the inventors of the present invention found that rubber asphalt is unsuitable for use alone as an exposed walking waterproof layer due to its flexibility. On the other hand, an exposed walking waterproof layer made of polyester resin using a hand-lay method has a strong adhesion to the base, so it has the disadvantage that it is difficult to follow the cracking stress of the base. However, it has been found that by forming a composite waterproof layer by combining these two layers, the deficiencies of both can be compensated for and an excellent exposed walking composite waterproof layer can be obtained.

を形成密着して優れた複合防水層を完成した。Rubber asphalt sheets are adhesive and can be soft bonded to the base and follow the expansion and contraction of the base, so the non-woven fabric attached to the surface of the rubber asphalt layer is coated and impregnated with polyester resin and reinforced with glass fiber. Then, an FRP layer was formed and adhered to create an excellent composite waterproof layer.

ある。That is, the present invention provides an FR made of a rubber asphalt sheet with a nonwoven fabric adhered to its surface, and a polyester resin reinforced with glass fiber and coated with a polyester resin so as to impregnate the nonwoven fabric.
This is an exposed walking composite waterproof layer characterized by comprising a P layer.
以下、本発明に係わる露出歩行複合防水層について具体
的に説明する。Hereinafter, the exposed walking composite waterproof layer according to the present invention will be explained in detail.
本発明において用いられるゴムアスファルトシートは例

あった。This rubber asphalt sheet has a tensile strength of 14k.
g/d (20°C), and the tensile elongation rate was 80% (20°C).
また、本発明において用いられるＦＲＰ層の構成例は次
の通りである。Furthermore, an example of the structure of the FRP layer used in the present invention is as follows.

At this time, the polyester resin 13 penetrates into the remaining half of the nonwoven fabric 21 that is semi-impregnated and attached to the rubber asphalt layer 22, and a glass mat is further inserted to form the glass fiber 12.
At the same time, the anti-slip silica sand 11 is removed from the upper layer, and the FRP layer is crimped with a foam eraser roll so that the thickness of the FRP layer is about 1.5 cm, thereby forming an exposed walking waterproof layer. completed.
