DRILLING DEVICE FOR ROOFTOP SLAB HANGING HOLE
To provide a drilling device for a rooftop slab hanging hole capable of suppressing health problems of workers and deterioration of a working environment.SOLUTION: A drilling device for a rooftop slab hanging hole for drilling a rooftop slab to form a hanging hole for transfer comprises: a frame which is mounted on a floor surface of a rooftop slab; at least one core drill unit which is a dry core drill unit fixed to the frame and cuts the rooftop slab in an annular shape along the thickness direction of the rooftop slab so as to form a through hole; and a suction device which collects dust in the vicinity of a cutting point of the core drill unit and can prevent core debris from falling off from the inside of the core drill unit when the through hole is formed by a suction force.SELECTED DRAWING: Figure 1
【課題】作業者の健康被害や作業環境の悪化を抑制することができる屋上スラブ吊孔穿孔装置を提供する。【解決手段】屋上スラブ吊孔穿孔装置は、屋上スラブを穿孔して移送用の吊孔を形成するものであって、屋上スラブの床面上に載置される枠体と、枠体に固定される乾式のコアドリルユニットであって、屋上スラブを屋上スラブの厚さ方向に沿って円環状に切削して貫通孔を形成する少なくとも一つのコアドリルユニットと、コアドリルユニットの切削箇所近傍の集じんを行う吸引装置であって、吸引力により貫通孔を形成する際に生じるコアガラのコアドリルユニットの内部からの脱落を防止可能な吸引装置と、を備える。【選択図】 図１
