    • PROBLEM TO BE SOLVED: To surely and efficiently join waterproof sheets to each other by necessary minimum hot air. SOLUTION: When a hot air spray nozzle is used in the hot air fusion-bonding of the waterproof sheets, a pair of the waterproof sheets is arranged so that their edge parts are laid to overlap each other on a waterproof underlayer, while the upper sheet is wound up, the surfaces to be fusion-bonded together of the sheets are melted by blowing hot air, and the sheets are laid to overlap each other and fusion-bonded together. Openings are formed in the upper and lower surfaces, an opening connected in three directions to the joining surface in the front direction and the rear direction in relation to the advance direction of fusion-bonding work, and the hot air is ejected to the whole range of fusion. The sizes of the openings formed in the upper and lower surfaces are made to be 2-10% in relation to the width of nozzle. As regards the opening positioned in the front direction and the rear direction to the advance direction of the fusion-bonding work, an angle θ to the opening positioned on the joining surface is 90-130°, and the length of the opening positioned in the front direction and the rear direction is made 10-20% of the opening positioned on the joining surface.

    • 要解决的问题:通过必要的最小热空气来确保和有效地将防水片材彼此连接起来。 解决方案:当在防水薄片的热空气熔合中使用热空气喷嘴时,布置一对防水片,使得它们的边缘部分在防水底层上相互重叠,同时 上片被卷起,通过吹热风将片材熔合在一起的表面熔融,并将片材相互重叠并熔接在一起。 在上表面和下表面形成开口,开口相对于熔接作业的前进方向在三个方向上连接到前后方向的接合面,并且热空气喷射到整个范围 的融合。 在上表面和下表面上形成的开口的尺寸相对于喷嘴的宽度为2-10%。 关于位于熔接作业的前方向的前方向和后方的开口,与接合面上的开口的角度θ为90〜130°,位于 前方向和后方向成为位于接合面上的开口的10〜20%。 版权所有(C)2005,JPO&NCIPI
