BLIND COVER AND CONSTRUCTION METHOD OF FIREPROOF STRUCTURE

PROBLEM TO BE SOLVED: To provide a blind cover capable of blindfolding an open hole even when a pipe body with a different outer diameter is inserted.SOLUTION: A blind cover 1 includes a frame-like substrate 2 arranged so as to surround an open hole on an outer surface of a partition body, and a plurality of covering pieces 3 attached to the substrate 2 so as to enable derricking operation with a base end side as a fulcrum. The covering pieces 3 are formed into a curved surface shape of directing a lengthwise direction and a width direction outward and forming a convex shape, and are consecutively arranged in a circumferential direction of the substrate 2 so that parts of the covering pieces are overlapped with each other.SELECTED DRAWING: Figure 1 【課題】異なる外径の管体が貫通孔に挿通されていても、貫通孔を目隠しすることができる目隠しカバーを提供する。【解決手段】目隠しカバー１は、区画体の外面に貫通孔を囲むように配置される枠状の基板２と、基板２に、基端側を支点に起伏動作可能に取り付けられた複数の覆い片３とを備える。複数の覆い片３は、長さ方向及び幅方向ともに外側に向けて凸状をなす湾曲面形状に形成されており、一部同士が重なるように基板２の周方向に連続して配置される。【選択図】図１
