公昭６２−６５０４号公報に記載されたものがある。2. Description of the Related Art As a waterproof sheet of this type, there is, for example, a sheet described in Japanese Patent Publication No. 62-6504.

る。As shown in FIG. 2, this waterproof sheet is composed of two layers of a thermoplastic resin sheet such as polyvinyl chloride.
The upper surface layer 51 is a hard sheet having better weather resistance than the lower surface layer 52, and a reinforcing fiber 53 as a tension member is sandwiched between the two layers 51 and 52.

張や収縮を吸収して亀裂等の破損が防止される。As described above, since the upper surface layer 51 is hard and rich in weather resistance, it is hardly deteriorated even in an exposed state.
It can withstand walking, and since the linear expansion coefficient of the waterproof sheet itself is reduced by the reinforcing fibers 53, wrinkles are unlikely to occur even when floated and adhered, and expansion and shrinkage of the foundation of the body are absorbed. Thus, damage such as cracks is prevented.

により層間のはく離を防止することにある。However, in the two-layer waterproof sheet having different hardnesses as described above, displacement occurs between both layers due to thermal shock such as volatilization of a plasticizer and a temperature change at a high temperature, and walking occurs. Also, the strain differs depending on the physical impact due to the above. For this reason, if the reinforcing fiber is sandwiched between the two layers, there is a disadvantage that the bonding strength at the interface is weakened and the upper layer is easily peeled off. Therefore,
An object of the present invention is to prevent separation between layers by improving this type of waterproof sheet.

In the waterproof sheet having the woven fabric sandwiched therebetween, the reinforcing fabric is sandwiched between the same layers.

脂系の５層から成る積層シートである。Embodiments will be described below with reference to the drawings. As shown in FIG. 1, this waterproof sheet is a laminated sheet composed of five layers of a thermoplastic resin.

織物としてガラスクロス６が挾み込まれている。The uppermost layer 1 is a fluorine or acrylic resin sheet having excellent weather resistance, and the remaining four layers are polyvinyl chloride resin sheets. In this polyvinyl chloride resin sheet layer, the upper layer 2 and the lower layer 5 are hard layers, and the intermediate layers 3, 4 sandwiched between the hard layers are soft layers of the same quality. A glass cloth 6 is sandwiched between the intermediate layers 3 and 4 as a reinforcing fabric.

る。In the waterproof sheet constructed as described above, since the glass cloth 6 is sandwiched between soft layers of the same quality, for example, shrinkage due to volatilization of the plasticizer at a high temperature or deformation due to impact such as walking. Also occurs in the same manner, no displacement occurs between the two layers, and peeling at this portion is prevented.

系のものも使用できる。In this case, the reinforcing fabric is sandwiched between the soft layers. However, the present invention is not limited to this, and the reinforcing fabric may be sandwiched between hard layers of the same quality. However, the shock due to the tightening force on the reinforcing fabric that occurs at low temperatures,
It is preferable that the layer is sandwiched between the soft layers because the layer is softened and cracks in the upper and lower layers can be prevented. In addition, as the thermoplastic resin, a polyethylene-based resin can be used in addition to the polyvinyl chloride-based resin.

物を挾み込んだ部分からの上層のはく離が防止される。As described above, the waterproof sheet of the present invention employs a structure in which the reinforcing fabric is sandwiched between the same layers, so that both layers are similarly contracted by external factors such as heat and impact. ,
Because of the deformation, no displacement occurs between the two layers, and the separation of the upper layer from the portion sandwiching the reinforcing fabric is prevented.
