DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an asbestos removing device, a removing head and a removing tool used for removing asbestos provided on a wall of an existing building.

[0002]

2. Description of the Related Art Asbestos has been used as a heat insulating material, a sound insulating material and a sound absorbing material which is sprayed onto a ceiling or a wall surface of a building made of concrete or the like and has a thickness of 1 cm to 4 cm.

[0003] However, when the asbestos is scattered due to deterioration or damage, there is a concern that the asbestos may affect a building user or a construction worker. For this reason, asbestos is currently banned. Also, in existing buildings using asbestos as a heat insulating material in the past, asbestos has been removed for the reasons described above.

Conventionally, asbestos provided by spraying on the wall of a building or the like has been removed by the following procedure. First, the entire work place is isolated from the outside by a curing sheet made of a vinyl sheet or the like, and is kept at a pressure lower than the atmospheric pressure using a ventilation device or the like.
Then, water or the like is infiltrated into the asbestos, and as shown in FIG. 5, an operator 102 scrapes off the asbestos 104 in the work place 101 using a removing tool 103 such as, for example, a wrench rod.

[0005] Asbestos remaining on the wall of the building after removal by the removal tool 103 is scraped off using a brush or the like. The asbestos that has been scraped off and scraped is collected and packed in a bag, and the asbestos remaining on the wall of the building is sealed with a chemical solution. Then, the cured sheet is washed with water or the like to remove asbestos attached to the sheet and packed in a bag.

[0006]

In the above-described conventional asbestos removing method, as shown in FIG. 5, when the operator 102 uses the removing tool 103 to scrape the asbestos 104, the removing tool 103 and the asbestos are removed. Due to the mechanical contact, as shown, the removed pieces of asbestos 104 are scattered in the work place 101.

For this reason, as shown in FIG. 6, the atmosphere inside the work place 101 is discharged to the outside 106 of the work place 101 by using a dust removing device 105 or the like. In order to suppress the dust concentration of the asbestos 104 discharged to the outside 106, it is necessary to improve the dust collection efficiency of the filter of the dust removal device 105. However, when the dust collection efficiency of the filter is improved, the filter becomes clogged or the like, and the atmosphere of the work place 101 becomes
May not be discharged to

Further, as described above, most of the asbestos removal work conventionally performed depends on the manual work of the worker 102, which is inefficient in terms of time and economy. Work has been done. Furthermore, worker 1
In No. 02, it is necessary to take sufficient dust-proof measures, for example, by wearing a protective suit or a dust-proof mask, and the workability is reduced.

Further, in the above-mentioned conventional asbestos removal method, the entire inside of the work place 101 is cured several times with a vinyl sheet or the like, and the entrance of the worker 102 and the entrance 107 of the removal tool 103 (see FIG. 6) is separated from the outside 106 by, for example, providing a separate section. For this reason, the labor and cost required for preparation such as the above-mentioned curing are increased.

[0010] Accordingly, an object of the present invention is to reduce asbestos scattering as much as possible in the work of removing asbestos from the walls of an existing building, thereby suppressing the influence on workers and economically in terms of time. Another object of the present invention is to provide an asbestos removing device, a removing head, and a removing tool that can efficiently perform a removing operation.
