CUTTER CONCRETE CORE CUTTER AND METHOD OF FORMING HOLE
PROBLEM TO BE SOLVED: To provide a concrete core cutter and a method of forming a hole which make it possible to form a hole extending into a cylindrical wall of a concrete structure in a direction other than a radial direction.SOLUTION: A concrete core cutter (10, 10') comprises: a cutter blade (12) consisting of an annular member (16) supporting a plurality of bits; a plurality of axial members (18) separably connected to the annular member and extending in the axial direction of the annular member; radial members (20) each separably connected to the plurality of axial members and extending radially inward of the annular member; and a plurality of other axial members (18') each attachable to the axial member (18), The concrete core cutter (10) in which the other axial members (18 ') are not attached and the concrete core cutter (10') in which the other axial members (18 ') are attached cut a part of the cylindrical wall (104) of the concrete structure and a part of the remainder, respectively, to form a hole (105) in the wall.SELECTED DRAWING: Figure 1
【課題】コンクリート構造物の円筒状の壁に放射方向以外の方向へ伸びる孔を形成することを可能とするコンクリートコアカッター及び孔の形成方法を提供すること。【解決手段】コンクリートコアカッター(10,10’)は、複数のビットを支持する環状部材(16)からなるカッター刃(12)と、環状部材に分離可能に接続され環状部材の軸線方向へ伸びる複数の軸線方向部材(18)と、複数の軸線方向部材にそれぞれ分離可能に接続され環状部材の径方向内方へ伸びる径方向部材(20)と、軸線方向部材に継ぎ足し可能である複数の他の軸線方向部材(18’)とを備える。他の軸線方向部材(18’)が継ぎ足されていないコンクリートコアカッター(10)と継ぎ足された他の軸線方向部材(18’)を含むコンクリートコアカッター(10’)とにより、それぞれ、コンクリート構造物の円筒状の壁(104)の一部及び残りの一部を切削し、壁に孔(105)を形成する。【選択図】図１
