Claims (1)
- 地上にある既設の鉄塔または所定部分まで組み立てられた鉄塔の上部に、ヘリコプタにより運ばれる鉄塔構成部材の荷受け台及び吊り下げ用の滑車とワイヤを設置し、前記荷受け台には水平方向に延びた棒状の荷受け部材を取り付け、前記ヘリコプタ側から係合及び係合解除可能な係合部材を前記ヘリコプタに設け、前記ヘリコプタにより運ばれる前記鉄塔構成部材には、前記荷受け部材に係合可能なフックを固定し、前記鉄塔構成部材を前記ヘリコプタの係合部材に係合させ吊り下げた状態で前記鉄塔構成部材を搬送し、前記荷受け部材に前記フックを係合させた後、前記ヘリコプタ側から前記係合部材の係合を解除して、前記鉄塔構成部材を前記ヘリコプタから切り離し、この後、前記荷受け部材に係合した前記鉄塔構成部材に前記ワイヤを掛けて前記滑車を用いて所定の位置に降下させて、既に組み立てられた鉄塔構成部材に前記鉄塔構成部材を組み付け、さらに、この組み付けられた前記鉄塔構成部材の上部に、互いに対向して長手方向に対して各々塔心方向に傾斜して延びた複数の荷受け用ガイド部を設置し、予め所定の枠組みに組み立てられた鉄塔枠部材を前記ヘリコプタにより搬送し、前記ヘリコプタにより搬送された前記鉄塔枠部材の下端部を前記ガイド部に沿って前記鉄塔構成部材上に降ろし、この後、前記ガイド部により位置決めされた前記鉄塔枠部材を、既に組み立てられた前記鉄塔構成部材に固定することを特徴とするヘリコプタによる鉄塔組立工法。
