CEILING SURFACE REPAIR METHOD AND DEFOAMING TOOL OF CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a ceiling surface repair method and a defoaming tool of a concrete structure capable of effectively removing contaminated air between a ceiling surface and a sheet material to improve the efficiency of defoaming processing.SOLUTION: The method includes an arranging step S1, a pressing step S2, and a defoaming step S3. In the arranging step S1, a sheet material 21 is placed on a ceiling surface 20a of a concrete structure 20 via a resin liquid having a viscosity in the range of 20 Pa s or more and 200 Pa s or less at 20°C. In the pressing step S2, using a defoaming tool 10 having a rotating body 11, a long handle 12 and a holding part 13 held by a user, the rotating body 11 of the defoaming tool 10 is pressed against the ceiling surface 20a keeping the contact angle of the long handle 12 to the ceiling face 20a to be within the range of 40° to 60°. In the defoaming step S3, the rotating body 11 is kept in rotation in contact with the ceiling surface 20a while maintaining the contact angle of the long handle 12 to remove the contaminated air between the sheet material 21 and the ceiling surface 20a.SELECTED DRAWING: Figure 5
【課題】天井面とシート材との間に混入した空気を効果的に除去して脱泡処理の効率化を図ることが可能なコンクリート構造物の天井面補修方法および脱泡具を提供する。【解決手段】本方法は、配置工程Ｓ１、押圧工程Ｓ２、脱泡工程Ｓ３を備えている。配置工程Ｓ１は、２０℃での粘度が２０Ｐａ・ｓ以上２００Ｐａ・ｓ以下の範囲の樹脂液を介してシート材２１をコンクリート構造物２０の天井面２０ａに配置する。押圧工程Ｓ２は、回転体１１と、長尺柄１２と、使用者に把持される把持部１３とを有する脱泡具１０を用いて、天井面２０ａに対する長尺柄１２の接触角が４０°〜６０°の範囲となる角度で脱泡具１０の回転体１１を天井面２０ａに押し当てる。脱泡工程Ｓ３は、長尺柄１２の接触角を維持したまま回転体１１を天井面２０ａに接触させた状態で回転させて、シート材２１と天井面２０ａとの間に混入した空気を除去する。【選択図】図５
