To provide a sleeve fixture for a through-hole for reducing dangerous height work and work man-hours of sleeve construction in a reinforced concrete building.SOLUTION: The present invention comprises: a closing plate 2 of a substantially dish-shaped cuttable thin plate material adapted to the outer diameter of a sleeve 1 of each size; a bottom plate 4 having an outer diameter almost equal to the inner diameter of the sleeve 1; a hollow shaft column 5 erected at the center of the bottom plate 4; and a fixture 3 in which a fixing nail 8 penetrates from the center of the top part of the shaft column 5 to below the bottom plate 4, a plurality of inner diameter locking projection walls 6 for sleeve 1 are erected radially from the side face of the shaft column 5 to the outer edge of the bottom plate 4, and the upper end parts of the locking projection walls 6 are each shaped to have an arc shape. A hole is eventually formed in a concrete layer, but the closing plate 2 is left on the bottom of the hole.SELECTED DRAWING: Figure 1
【課題】 鉄筋コンクリート建築物における、スリーブ工事の危険な高所作業や作業工数の低減を図る貫通孔用スリーブ固定具を提供する。【解決手段】 各サイズのスリーブ１外径に適合する略皿形状の切削可能な薄板材の閉塞板２と、スリーブ１内径とほぼ等しい外径の底板４と該底板４中央に立設した中空の軸柱５と該軸柱５の頂部中心から前記底板４下まで固定釘８を貫通させ、前記軸柱５側面から放射状に前記底板４外縁まで複数枚のスリーブ１内径係止用突起壁６を立設し、該係止用突起壁６上端部を円弧状に形成した固定具３とから構成されており、最終的にコンクリート層には孔が形設されるが、孔底には閉塞板２が残るようにしたものである。【選択図】 図１
