To prevent water from leaking downward in a suspended scaffold constructed below a structure.SOLUTION: A suspension scaffold 1 includes: a floor member 2; a suspension member 3; a water-impermeable sheet 4 laid on the upper surface of the floor member 2 to form a penetration portion 5; and waterproof means 6 for blocking a flow of water in the penetration portion 5. The waterproof means 6 has: a tubular member 20 which is water-tightly attached to the upper surface of the water-impermeable sheet 4 and extends upward around the penetration portion 5; and a shaft member 10 at least a part of which is arranged inside the cylinder member 20 having a function to prevent water from flowing inside, provided in the middle of the suspension member 3; and a binding member 30 which stops water between the inner surface of the tubular member 20 and the outer surface of the shaft member 10. Since the tubular member 20 surrounds water-tightly the penetration portion 5 and the binding member 30 stops the water between the tubular member 20 and the shaft member 10, it is possible to prevent cleansing wastewater from leaking from the penetration portion 5. Since the tubular member 20 and the shaft member 10 are configured to stop water, the water can be reliably stopped with a simple operation regardless of shape of the suspension member 3.SELECTED DRAWING: Figure 3
【課題】構造物の下方に構築される吊足場において、下方への水の漏出を防止する。【解決手段】吊足場１は、床部材２、吊部材３、床部材２の上面に敷設され貫通部５が形成された遮水シート４、及び貫通部５における水の流通を阻止する防水手段６を含む。防水手段６は、遮水シート４の上面に水密的に取り付けられ貫通部５を囲んで上方へ延びる筒部材２０と、吊部材３の途中に設けられその内部の通水を阻止する機能を有し筒部材２０の内部に少なくとも一部が配置される軸部材１０と、筒部材２０の内面と軸部材１０の外面との間を止水する結束部材３０とを有する。筒部材２０が貫通部５の周囲を水密的に囲うと共に、結束部材３０によって筒部材２０と軸部材１０との間を止水するから、洗浄廃水が貫通部５から漏水するのを防止できる。筒部材２０と軸部材１０とで止水する構成なので、吊部材３の形状に関わらず簡単な作業で確実に止水することができる。【選択図】 図３
