【発明の詳細な説明】 「産業上の利用分野」 本発明は大形透明水槽等を製造するためのアク
リル透明板接着法に関するものである。
「従来の技術」 従来大形アクリル透明板による水槽の隣接側板
（2000mm×1000mm×1000mm×20mm）の直角接着は
外部盛上式又は膨潤接着法が採用された。しかし
外部盛上式では接着剤内部の空気残留を伴い気泡
を残留して透明度を向上し難いばかりか外部盛上
部（肉盛部）の鋸切断痕跡による半透明部を生じ
これを鏡面研磨するため多大の労力と時間を要
し、かつ接着強度は70〜80％であり水槽の強度を
向上し難い欠陥があつた。又膨潤接着法では接着
幅が0.05mmと薄いため気泡の排出が困難でそのた
め接着強度を向上し難くかつ作業能率を向上し難
い欠陥がある。
即ち外部盛上式接着法では第１３図示すように
一方の側板３′の一端を他方の側板２′の側面から
突出させて段１５を形成し、他方の側板２′の端
面を斜面となし、両側板２′，３′の内側交差面に
アルミ箔１６で閉鎖し、上記突出段１５に堰板１
７を配置して重合アクリルボンド（アクリル系接
着剤４）を堰板１７の内側から供給し楔形空間を
同接着剤４で充填し両側板２′，３′を接着した後
同第１３図仮想線１８に沿つて切断した。
ところが上記外部盛上式接着法ではアルミ箔１
６側から楔形空間の接着剤４内に空気が進入する
（接着剤４が低粘性であるため）。
又第１３図の従来法では仮想線１８に沿つて切
断した後斜交仮想線１９に沿つて切断して角の交
差面（糸面）を形成し切断に２工程を要し、かつ
内側交差面にアールを形成し難くそのためにも強
度を向上することは困難であつた。
「発明が解決しようとする問題点」 本発明は接着部に気泡がなく透明度を向上し一
度の切断工程によつて角の交差面（角の糸面）を

「問題点を解決するための手段及び手順」 本発明は隣接アクリル透明板の隣接縁に片刃面
を形成し、同片刃面の先端部を接して同片刃面間
に楔形空間を保持し、かつ一方のアクリル透明板
の片刃面の先端を他方のアクリル透明板の外面の
外側に若干突出し、同突出部と他方のアクリル透
明板の外面との境界部にアクリル系接着剤を塗着
した後上記楔形空間内にアクリル系接着剤を充填
硬化させた後上記両片刃面の先端部を上記境界部
に沿つて切断し、上記両透明板の外面間に交差面
を形成することを特徴とするアクリル透明板接着
法によつて構成される。
「作用」 従つて一方の透明板３の片刃面５の先端７を他
方のアクリル透明板２の外面の外側に若干突出し
た部分にアクリル係接着剤４を保持して境界部８
に同接着剤４を塗着することができ同接着剤４に
よつて境界部８が密封され同部８から楔形空間６
内への空気進入が阻止される。そして同空間６内
に両透明板２，３の内側交差部側から上記接着剤
４を注入すると境界部８から空気進入がなく同接
着剤４の流動性によつて同空間６は充填され同空
間６内の空気は浮上して開口部から排出される。
そして硬化後上記内側交差部側の肉盛接着剤４を
削つて凹アール面を形成することができる。
「実施例」 長方形アクリル透明底板１の上面外周に互に隣
接直交するアクリル透明側板２，３を載置する。
同側板２，３の下端は第９図、第１０図に示すよ
