【考案の詳細な説明】
本考案は防水シートの改良に関するものであ
る。[Detailed Description of the Invention] The present invention relates to an improvement of a waterproof sheet.
冷凍倉庫の壁面や断熱配管を防湿するシートと

遮水兼機械的補強のためにプラスチツクシートを
積層したものが公知であるが、プラスチツクシー
トの厚さをかなり厚くする必要があり、柔軟性に
劣るといつた不利がある。 A well-known sheet for moisture-proofing walls and heat-insulating piping in cold storage warehouses is a sheet made by laminating a non-vulcanized rubber layer with an excellent sealing effect and a plastic sheet for water-blocking and mechanical reinforcement. It has the disadvantage that it needs to be quite thick and has poor flexibility.

のである。 The waterproof sheet according to the present invention has a structure that can eliminate such problems, and is made by laminating a plastic film on a reinforcing sheet made by crisscrossing or weaving stretched tapes, and partially bonding the laminated interface to one side of the composite. It is characterized by having a non-vulcanized rubber layer.
以下、図面により本考案を説明する。 The present invention will be explained below with reference to the drawings.

A reinforcing sheet 1 and a plastic film 2 are bonded to each other by thermocompression bonding 3 at the ends of the laminate A.

使用することもでき、何れの場合もテープの交叉
箇所は摺動自在である。 Instead of the woven fabric of the above-mentioned stretched plastic tape, it is also possible to use a stretched plastic tape that is crossed in the vertical and horizontal directions, and in either case, the crossing points of the tapes are slidable.
第３図は本考案に係る防水シートを示し、上記

せることができる。 The waterproof sheet according to the present invention has the above-mentioned structure, and has excellent tensile strength because it uses a crisscross or woven body of stretched tape as the reinforcing sheet. Because of this excellent tensile strength, the reinforcing sheet can be made thin, and the thickness of the laminate of the reinforcing sheet and the plastic film can therefore be made thin, resulting in excellent flexibility. In addition, since the reinforcing sheet and the plastic film are partially bonded, most of the crossing points of the stretched tape on the reinforcing sheet can slide freely, and the vertical and horizontal stretched tapes can move freely, so it can be used on complex surfaces. It can also be blended well.
