本発明はタンクの建設工事に使用する回転吊り足場の組
立方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for assembling a rotating suspended scaffold for use in tank construction work.
内槽と外槽の間に保冷層を設けた二重殻タンクの建設工
事においては、タンク屋根の内周に沿い設けたレールを
使用して工事用足場をタンク内周に沿い移動自在に吊下
げ、該工事用足場を用いて保冷材の組付け、メンブレン
の張付け、点検等を行なっていた。When constructing a double-shell tank with a cold insulation layer between the inner tank and the outer tank, construction scaffolding is suspended along the inner circumference of the tank using rails installed along the inner circumference of the tank roof. They used the construction scaffolding to assemble cold insulation materials, attach membranes, and conduct inspections.
従来かかる工事のための工事用足場の組立ては、先ず地
上で足場ユニットを組立て、これを屋根に設けた工事孔
からタンク内に搬入し、次いでタンク底板上でこれら搬
入したユニットにより足場を組立て、最後に該組立てた
足場をタンク屋根内周のレールに吊下げていた。Conventionally, construction scaffolding for such construction work was assembled by first assembling scaffolding units on the ground, carrying these into the tank through a construction hole provided in the roof, and then assembling the scaffolding with these carried units on the tank bottom plate. Finally, the assembled scaffolding was suspended from a rail around the inner circumference of the tank roof.
しかしかかる従来の組立方法では、
（１）地上で組立てたユニットを屋根の工事孔を通して
搬入するので、該工事孔を大きくする必要がある。従っ
て大きな工事孔がとれないような場合には、適用できな
い。However, in such a conventional assembly method, (1) the unit assembled on the ground is brought in through a construction hole in the roof, so the construction hole needs to be enlarged. Therefore, it cannot be applied in cases where large construction holes cannot be made.
（１１）高所作業が多く危険性が大である。(11) There is a lot of work at heights, which is very dangerous.
（ｉｉｉ）足場ユニットの組立のために別の足場が必要
となる。(iii) Separate scaffolding is required for assembly of the scaffolding unit.
等の問題点を有していた。It had the following problems.
本発明はかかる問題を解決するためになしたもので、作
業ステージや枠部材等の屋根部材をタンク内に搬入した

ンク屋根に設置されているホイストにより吊上げて該吊
上げだブロックの下に別のブロックを継ぎ足し、以後同
様にして次々とブロックを継ぎ足し吊上げて行くことを
特徴とするものである。The present invention was made to solve this problem, and after carrying roof members such as a work stage and frame members into the tank, they are assembled into blocks on the tank bottom plate, and the blocks are assembled into blocks by a hoist installed on the tank roof. It is characterized by lifting the block by adding another block under the lifted block, and subsequently adding blocks one after another in the same manner and lifting it up.
