description To provide a detachably-assembled-type band saw that can be brought into a room even if the doorway of the room where large equipment is installed inside the reactor building is bent by a radiation protection wall.SOLUTION: A detachably-assembled-type band saw 10 comprises: cutting means 20 having an endless band saw blade and a rotation mechanism thereof; upper and lower frames 14, 16 for supporting upper and lower surfaces of the cutting means 20; and an elevating part 30 which is connected between both ends of the upper and lower frames 14, 16, and can vertically move the cutting means 20. The upper and lower frames 14, 16 and the elevating part 30 can be detached into a plurality of parts or assembled from the plurality of detached parts, along a longitudinal direction.SELECTED DRAWING: Figure 1 【課題】原子炉建屋内で大型設備機器を据え付けた部屋の出入口が放射線の防護壁で屈曲していても、室内に持ち込み可能な分解組立式バンドソーを提供する。【解決手段】本発明の分解組立式バンドソー10は、無端帯鋸刃とその回転機構を有する切断手段20と、前記切断手段20の上下面を支持する上下フレーム14,16と、前記上下フレーム14,16の両端の間に接続して前記切断手段20を昇降移動可能な昇降部30を有し、前記上下フレーム14,16及び昇降部30は長手方向に沿って複数のパーツに分割又は前記パーツにより組み立て可能なことを特徴としている。【選択図】 図1
