【考案の詳細な説明】
この考案は、建築用テント膜材に関するもので
ある。[Detailed description of the invention] This invention relates to a tent membrane material for construction.
近年、競技場、野球場等の大型建造物の屋根と
して、例えば第１図に示すように、建築用テント
膜を張つた空気支持方式のものが採用されつつあ
る。 In recent years, roofs of large buildings such as stadiums, baseball stadiums, etc., are increasingly being equipped with air-supported roofs covered with architectural tent membranes, as shown in FIG. 1, for example.
上記空気支持方式の屋根材として使用される建
築用テント膜材は、経年変化の生じない耐候性に
すぐれたものでなければならないことは勿論、あ
る程度の通気性と柔軟性を必要とする。 The construction tent membrane material used as the roofing material of the above-mentioned air support system must not only have excellent weather resistance that does not change over time, but also requires a certain degree of air permeability and flexibility.
ところで、従来、上記の用途に使用される建築
用テント膜材として、フアイバーグラス製の織物
に弗素樹脂を含浸させたものが開発されている。 By the way, as a construction tent membrane material used for the above-mentioned purpose, a material in which a fiberglass fabric is impregnated with a fluororesin has been developed.
しかしながら、このものは、織物に弗素樹脂を
含浸させたものであるから、織物の織目に弗素樹
脂が詰まり、通気性を全く有しないと共に、織物
の縦糸と横糸が交差する部分が弗素樹脂で結合さ
れ、柔軟性に欠けるという欠点があつた。 However, since this fabric is made by impregnating the fabric with fluororesin, the weave of the fabric is clogged with fluororesin and has no air permeability at all, and the portion where the warp and weft of the fabric intersect is filled with fluororesin. It had the disadvantage of being tied together and lacking in flexibility.
そこで、この考案は、耐候性に優れ、しかも通
気性と柔軟性に富む建築用テント膜材を提供する
ことを目的とする。 Therefore, the object of this invention is to provide a construction tent membrane material that has excellent weather resistance, breathability, and flexibility.
この考案の建築用テント膜材１は、芯材２、弗

た糸４を織製してなる織物５によつて構成されて
いる。 The construction tent membrane material 1 of this invention is composed of a core material 2 and a fabric 5 woven from threads 4 impregnated or coated with a fluororesin 3 and fired.
上記弗素樹脂３としては、四弗化エチレン樹
脂、四弗化エチレン−六弗化プロピレン共重合樹
脂、三弗化塩化エチレン樹脂等を用いることがで
きる。 As the fluororesin 3, a tetrafluoroethylene resin, a tetrafluoroethylene-hexafluoropropylene copolymer resin, a trifluorochloroethylene resin, etc. can be used.
また、上記芯材２としては、カーボン繊維、ポ
リイミド繊維、ガラス繊維等を使用することがで
きる。この芯材２に上記弗素樹脂３を含浸して焼

ヨンを上記芯材２に含浸せしめた後、弗素樹脂の
融点以上の温度で弗素樹脂を加熱焼成すればよ
い。弗素樹脂の含浸量は、７〜35％特に13〜25％
位が最適である。 Further, as the core material 2, carbon fiber, polyimide fiber, glass fiber, etc. can be used. In order to impregnate the core material 2 with the fluororesin 3 and fire it, for example, after impregnating the core material 2 with a fluororesin dispersion, the fluororesin is heated and fired at a temperature higher than the melting point of the fluororesin. Bye. The amount of fluororesin impregnated is 7 to 35%, especially 13 to 25%.
The best position is
上記のように形成された糸４は、300〜3000デ
ニールのものが建築用テント膜材として適してお
り、特に500〜2000デニールの糸が最適であり、
また500デニール以下のものを何本か合せて撚り
をかけたものでもよい。 The yarn 4 formed as described above is suitable as a construction tent membrane material with a denier of 300 to 3000, and a yarn with a denier of 500 to 2000 is particularly suitable.
Alternatively, it may be made by twisting together several strands of 500 denier or less.
なお、上記織物５の目づれ、端部のほつれ等を
防止するために、織物５をさらに弗素樹脂の融点
以上の温度に加熱された熱板プレス又は熱ロール
間に通過させてもよい。 In order to prevent the fabric 5 from shifting, fraying at the edges, etc., the fabric 5 may be further passed through a hot plate press or heated rolls heated to a temperature equal to or higher than the melting point of the fluororesin.
この考案の建築用テント膜材は、上記のよう
に、弗素樹脂を含浸して焼成せしめた糸を織製し
てなる織物によつて構成したものであり、以下に
列挙するような効果を奏する。 As mentioned above, the architectural tent membrane material of this invention is constructed from a fabric made by weaving threads impregnated with fluororesin and fired, and has the following effects: .
(1) 織物を構成する糸自体に弗素樹脂が焼成され
ているので、耐候性、撥水性、難燃性等弗素樹
脂特有の特性を有する。(1) Since the fluororesin is baked into the threads that make up the fabric, it has properties unique to fluororesin, such as weather resistance, water repellency, and flame retardancy.
(2) 織物を構成する糸自体に予め弗素樹脂を焼成
してあるため、織目が弗素樹脂によつて塞がれ
ることがない。したがつて、通気性に優れてい
る。(2) Since the threads that make up the fabric are coated with fluororesin in advance, the weave will not be blocked by the fluororesin. Therefore, it has excellent breathability.
また、織物の織目の粗密を調整することによ
り、通気量を変化させることもできる。 Furthermore, the amount of ventilation can be changed by adjusting the density of the weave of the fabric.
(3) 織物を構成する糸自体に予め弗素樹脂を焼成
してあるため縦糸及び横糸相互のすべりが良好
であり、織物全体として柔軟性に富む。このた
め、この考案のテント膜材を張る場合に、テン
ト膜材に種々の方向に偏して力がかかつたとし
ても、上記縦糸、横糸相互の織目がその力を吸
収するようにずれ動くので、建築施工の際に皺
の発生がない。(3) Since the threads constituting the woven fabric are pre-fired with fluororesin, the warp and weft threads can easily slide against each other, and the woven fabric as a whole is highly flexible. Therefore, when tensioning the tent membrane material of this invention, even if forces are applied to the tent membrane material unevenly in various directions, the weave of the warp and weft yarns will shift to absorb the force. Because it moves, wrinkles do not occur during construction.
