【発明の詳細な説明】 （産業上の利用分野） 本発明は、弗素樹脂被覆布の接合構造に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a joining structure for fluororesin-coated cloth.
詳細には、競技場、体育館、屋外レストランなとの屋根
材として使用される弗素樹脂被覆布の接合部分における
液密性能を高めた弗素樹脂被覆布の接合構造に関する。In particular, the present invention relates to a joint structure of fluororesin-coated cloth that has improved liquid-tight performance at the joints of fluororesin-coated cloth used as roofing materials for stadiums, gymnasiums, outdoor restaurants, etc.
（従来の技術）
近時、競技場、体育館、屋外レストランなとの大規模な
構築物の屋根材として、弗素樹脂被覆布が多く使用され
ている。(Prior Art) In recent years, fluororesin-coated fabrics have been widely used as roofing materials for large-scale structures such as stadiums, gymnasiums, and outdoor restaurants.
競技場なとの構築物Ｃまきわめて大きな屋根面積を有す
るため、弗素樹脂被覆布をその屋根材として使用すると
きは、多数接合する必要がある。Since the stadium structure C has a very large roof area, when fluororesin-coated fabric is used as the roofing material, it is necessary to join many pieces of fabric together.
従来、弗素樹脂被覆布の接合は、接着或いは縫着なとの
手法により行われていた。Conventionally, fluororesin-coated fabrics have been joined by methods such as adhesion or sewing.
ところが、上記の手法により接合される弗素樹脂被覆布

布の接合端面は、弗素樹脂によって、被覆されていない
状態となる。このため、弗素樹脂被覆布端部の接合はな
されても、この接合端面を通して雨水が侵入することζ
こなる。However, the fluororesin-coated fabric joined by the above method is cut to match the size and shape of the roof surface of the structure in a factory or on-site. It is not covered by the resin. For this reason, even if the ends of the fluororesin-coated fabric are joined, rainwater may enter through the joined end surfaces.
This will happen.
このようにして、弗素樹脂被覆布内（こ侵入した雨 −
水己ま、弗素樹脂被覆布の透光性能を低下させたり、膜

ていた。In this way, the inside of the fluororesin-coated fabric (the rain that has entered)
The water itself degrades the light transmitting performance of the fluororesin-coated fabric and impairs the aesthetic appearance of the fluororesin-coated fabric as a membrane material.

た弗素樹脂被覆布の接合構造を提案している。In Japanese Patent Application Laid-Open No. 62-92840, the applicant has developed a strained fluororesin to improve the liquid-tightness of the joints of fluororesin-coated fabrics and to prevent rainwater from entering the edges of the fluororesin-coated fabrics. We are proposing a joining structure for covering cloth.

ラス繊維布の接合構造である。As shown in FIG. 4, the present invention provides a membrane body in which the membrane material (1) is glass cloth coated with a fluororesin (2), in which two or more of the membrane materials (1) The fluororesin (2) is placed so as to cover the joint end surface of the joint surface, and then the membrane material (1) and the fluororesin (2) are integrally heat-sealed from below E to closely join them. This is a bonded structure of glass fiber cloth coated with fluororesin in a membrane body.
上記接合構造によれは、接合端面が弗素樹脂によって覆
われていることから、接合端面からの雨水の侵入は確実
に防止させることになる。According to the above-mentioned joint structure, since the joint end faces are covered with a fluororesin, rainwater can be reliably prevented from entering from the joint end faces.

る。(Problem to be Solved by the Invention) However, in the joining structure described in JP-A No. 62-92840, when the fluororesin covering the joining end surface is heat-sealed from above and below with an iron, Another problem was that a portion of the molten fluororesin was fused to the heating surface of the iron. Therefore, it was necessary to stop the heat sealing operation and remove the fused material. This is because if the fluororesin remains fused to the heated surface of a processed material such as an iron and heat-seals another bonded end surface, the fluororesin that was fused to the heated surface of the iron will damage the bond. This is because it may stick to the end face and spoil the aesthetic appearance of the joined end face.

This invention is a further improvement to the invention described in Publication No. 40, and the problems it attempts to solve are the prevention of rainwater entering the edges of the fluororesin-coated fabric and the melting of the fluororesin onto the heated surface during heat sealing. It is worn.
