る。TECHNICAL FIELD The present invention relates to a peeling device for a surface of a concrete structure.
［従来技術］ 例えば原子力発電所の解体に際し、汚染度があまり高く
ない壁、床、天井の表面は人が入って汚染した表面をは
つって所定厚さ（例えば3mm）だけ剥離除去していた。[Prior Art] For example, when dismantling a nuclear power plant, the surfaces of walls, floors, and ceilings, which are not highly polluted, were peeled off by a predetermined thickness (for example, 3 mm) by taking in the contaminated surface due to the entry of people. .
しかし、上記の方法ははつり作業を入力で行っていたの
で作業性が悪く、また汚染物質が拡散して作業者および
周囲に被暴があった。However, in the above method, since the fishing work is carried out by inputting, the workability is poor, and the contaminants are diffused and exposed to the worker and the surroundings.

まれた領域の作業が終了したならば、吸引フードを動か
さねばならず、作業が面倒である。Generally, it is known to surround the tool with a closed suction hood so that dust generated when crushing a concrete structure does not scatter, and it is disclosed in JP-A-60-107600. However, in such a known technique, since the tool and the suction hood are separate bodies, when the work in the area surrounded by the suction hood is completed, the suction hood must be moved, which is troublesome.
また、特開昭57−15605号公報にははつりやドリル作業
中に生ずるダストを好適に処理する装置が開示されてい

角度を変え得るようになっており、広い面積範囲を簡単
にはつり作業を行うものではない。Further, Japanese Patent Application Laid-Open No. 57-15605 discloses an apparatus for suitably treating dust generated during fishing and drilling. However, such a known technique is designed so that the angle of the tool with respect to the wall can be changed, so that it is not easy to perform a hanging operation over a wide area range.

吸込み室内に運ぶことができる。[Explanation of action and effect] Therefore, at the time of operation, the gripping part of the chipping machine is gripped and the brush is pressed against the wall surface to carry out the chipping work. At that time, the chipping machine is suspended by the balancer rope,
It is possible to easily hang a large area of the wall surface. Dust is sucked into the suction chamber formed by the large diameter part and the elastic hood, but since the brush surrounds the opening, even if there is a relatively heavy peeling object, it should be held by the brush and carried into the suction chamber. You can
そして集塵パイプは大径部の底部に設けられているの
で、比較的に重いもので吸引されやすい。Since the dust collecting pipe is provided at the bottom of the large diameter portion, it is relatively heavy and easily sucked.

る。1 and 2, an air hose 3 is connected to an end portion of a grip portion 2 of a known piston type air hammer type fishing machine 1, and a coil-shaped elastic member is attached to a shaft portion 5 on the bit 4 side. A sliding guide 7 as a guide member is attached via the pressing adjustment spring 6 of FIG. The sliding guide 7
A large-diameter portion 8 is formed on one side of the large-diameter portion 8. A plurality of air guide blades 9, which are blade bodies, project inwardly in the large-diameter portion 8 and a dust collecting pipe 10 is provided at the bottom. A dust collecting hose 10a, which is a hose body, is connected via the hose body, and a rotary opening / closing shutter 11 that is a variable air inlet is provided on the end face.
A rubber hood 12, which is a dome-shaped elastic hood body, is bolted to the flange portion 8a of the large diameter portion 8.
A suction chamber R is formed by the rubber hood 12 and the large diameter portion 8 of the judo guide. An opening 13 is formed on the top of the rubber hood 12 close to the outer circumference of the tip of the bit 4 and has an inner diameter that is, for example, about twice the outer diameter of the tip of the bit 4. The edge of the opening 13 is parallel to the bit axis. An annular brush 14 which is a brush body of the above is provided. In the figure, reference numeral 15 is a hook that is a suspension member fixed to the large-diameter portion 8 of the sliding guide 7 so as to face the dust collecting hose 10 via a bracket 15a, and is a hook of a balancer mounted on a ceiling (not shown). It is suspended on the balancer rope 16.

して吸込み室Ｒ内に吸込ませる作用をする。The grip portion 2 of the chipping machine 1 is gripped, the annular brush 14 is pressed against the wall surface W, and the chipping machine 1 is operated. Then, in the suction chamber R, the rubber hood 12, which has been made negative pressure by the suction pressure of the blower device, is adsorbed to the wall surface W, and the pressing of the rubber hood 12 becomes almost unnecessary. The degree of adsorption of the rubber hood 12 can be adjusted arbitrarily by the amount of inflowing air by opening / closing the opening / closing shutter 11 to make the movement of the rubber hood 12 smooth. When the wall surface is peeled to a predetermined depth by the bit 4 of the chipping machine 1, the dust generated by the peeling, that is, the contaminant is directly caused by the negative pressure in the chamber R, or the dust caught between the eyes of the annular brush 14 is removed by the annular brush 14. Is sucked into the suction chamber R by the airflow indicated by the arrow A that flows at high speed between the eyes,
The dust is collected and collected from the dust collecting hose 10a by being guided to the dust collector. At this time, the air flow that has flowed in from the opening / closing shutter 11 is rectified by the air guide blades 9 and becomes an air flow indicated by the arrow B along the inner surface of the rubber hood 12, which entrains dust into the suction chamber R and also to the bit 4. Blow away the fine dust that has adhered to it. Further, the pressing adjustment spring 6 is used for the chipping machine 1
The impact is absorbed by the impact of, and it is prevented from being transmitted to the rubber hood 12 to improve workability. Then, when the rubber hood is moved, the annular brush 14 scrapes off the dust adhering to the wall surface W and sucks it into the suction chamber R.
