Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a method for safely and easily removing building materials containing inorganic fibers such as asbestos, such as walls. Concerning compact equipment.

<Conventional technology> Recently, in existing concrete structures such as old buildings, houses, etc., side walls with inorganic fibers such as asbestos added,
The problem is that asbestos and other substances gradually scatter into the air from building materials such as ceilings.

When asbestos in building materials turns into dust and scatters into the air, it can enter the human body, harming health and posing a risk of disease, so effective countermeasures are expected.

For this reason, existing asbestos-containing building materials are treated to prevent scattering, then the asbestos-containing building materials are removed, and the resulting asbestos-containing building materials are solidified with cement to become harmless waste.

In the method for removing asbestos-containing building materials at that time, the existing asbestos-containing building materials are first treated to prevent asbestos from scattering by impregnating them with an asbestos fixative, such as an aqueous polyvinylic alcohol solution, and then the treated building materials are treated with a hoe-shaped tool. Alternatively, asbestos-containing building materials were once dropped onto the floor by pressure, scratching, or scrubbing with a tool such as a wire brush, and then collected manually with a broom or the like and packed into bags.

(Problems to be Solved by the Invention) However, in the above conventional method, the building materials that have been treated to prevent scattering fall and scatter on the floor, creating dirt, which takes time and effort to collect, and requires a large-scale removal device. There was also a risk that asbestos would scatter again when the asbestos was dried after the removal work.

(Means for Solving the Problems) The present invention was made to solve the above problems, and is a compact asbestos material that can safely and easily remove asbestos-containing building materials (hereinafter simply referred to as "asbestos"). The present invention provides an asbestos removal device, which comprises an asbestos remover equipped with a suction member, a removed asbestos transfer hose, a removed asbestos collector, and a suction force generating blower. .

In the above, preferred configuration examples of asbestos removers include (1) a housing having a suction opening at one end and an asbestos scraping blade protruding from the opening, and a suction pipe at the other end; or (2) a housing having a suction opening at one end and an asbestos collection rotating brush attached to the frontage, and a suction pipe at the other end.

(Example) Embodiments of the present invention will be described based on the drawings.

- As an example, we will explain how to remove asbestos (a building material containing it) from walls.

First, asbestos-containing walls of an existing building are impregnated with an aqueous solution containing 0.9 to 2.3% by weight of modified polyvinyl alcohol to prevent asbestos fibers from scattering, and then as shown in the layout diagram in Figure 1, The asbestos remover 1 (see Figure 2) equipped with a scraping blade scrapes the treated asbestos, and using the suction force of the suction force generating blower 4, the asbestos is removed via the transfer hose 2 into the asbestos collector 3. to be collected.

In Figure 1, 1 is an asbestos remover, 2 is a transfer hose, 3 is a removed asbestos collector, 4 is a blower for generating suction force, 5 is an air blower, 6 is a vinyl cover for the work area, and 7 is a worker cleaning room. , 8 is a building compartment, and the removal work was carried out by installing a vinyl cover 6 in the work area within the building compartment 8, removing asbestos therein using an asbestos remover 1.1°, and placing it outside. This is done by collecting the removed asbestos into the removed asbestos collector 3 using the suction force of the suction force generating blower 4.

The worker cleaning room 7 is used for cleaning used equipment such as the asbestos remover 1 and work clothes.

Note that since the air inside the vinyl cover 6 is reduced by being sucked in by the asbestos remover 1, it is preferable to supply fresh air from outside using the blower 5.

Next, the asbestos remover 1 shown in FIG. 2 will be explained.

In the figure, 11 is an opening (suction port), 12 is a housing, 13 is an asbestos scraping blade, 14 is a means for adjusting the angle of the scraping blade,
15 is a handle.

This remover is for rough cutting, and when an operator holds the handle 15 and presses the scraping blade 13 against an asbestos-containing wall that has been treated to prevent asbestos scattering as described above, one end of the remover will be scraped. The asbestos to be removed is sucked through the opening 11 by suction force and transferred to the suction tube 15' inside the handle 15.

The remover 1 is provided with an angle adjusting means 14 so that the angle of the scraping blade 13 can be adjusted in order to selectively apply the required scraping depth.

The angle adjusting means 14 bends the base of the scraping blade 13 into an L-shape, rotatably supports the bent end at the opening end, and projects to the outside of the housing 12 at a part of the other end of the L-shape. A bolt is provided protrudingly, a wing screw is attached to the bolt, and a slide groove for the bolt is provided in the wall of the housing 12.

The asbestos remover 1° shown in FIG. 3 is for finishing used after the rough cutting.

In the figure, 16 is a rotating brush, 17 is an air motor, 18 is an air hose for driving the air motor, and one is a nylon brush.

Opening 11 of the remover 1'' against the rough-hewn wall surface
When the air motor 17 is rotated while gradually moving the rotary brush 16, the rotating brush 16 hits the rough-hewn wall surface and finely scrapes the rough surface to form a finished surface.

The rotating brush 16 is a mixture of hard and soft brushes, and a large number of nylon brushes are installed around the opening.

Next, the removed asbestos collector 3 will be explained.

This is shown in FIG. 4, in which a vinyl back 36 is open and provided in a container 31 and a container lid 32, and a water spray ring 34 for preventing asbestos scattering is disposed above the vinyl back 36. The spray ring 34 has a large number of pores through which spray water is spouted. Reference numeral 33 is an operating device for adjusting the jetting of the spray water, and one end thereof is connected to a water supply pipe 35, and the other end thereof is connected to a water supply pipe (not shown) connected to the spray ring 34.

In addition, in the removed asbestos collector 3, 1. Container 31
By the suction force from the suction hose 2' connected to one end, the asbestos to be removed is fed from the transfer hose 2 into the container 31 and dropped into the open plastic bag 36 for collection.

Furthermore, spray water is supplied at a timely manner to the removed asbestos A in the plastic bag to prevent the asbestos from scattering.

In addition, a wall of the container 31 of the asbestos collector 3 connected to the opening of the suction hose 2'' is provided with a mechanism to prevent asbestos fine silk from being sent to the suction force generating blower 4 and further being discharged outside the device. In order to do this, it is preferable to provide a filter member (not shown) in a detachable manner.

When removing and collecting asbestos using the above equipment, the work can be carried out safely and easily because the asbestos does not scatter and the asbestos does not come into direct contact with human hands6. It is small and easy to use, and the removed asbestos can be removed from the removed asbestos collector by simply squeezing the plastic bag and collected at a designated location.

(Effects of the Invention) As explained above, according to the method of the present invention, when asbestos is removed and recovered, the asbestos does not scatter and the asbestos does not come into direct contact with human hands, making the work easier. It can be carried out safely and easily.

In addition, the remover is small and easy to use, and the removed asbestos collector and the suction force generating blower are also connected, making the entire device compact.

The removed asbestos can also be taken out of the removed asbestos collector by simply squeezing the plastic bag and accumulated at a predetermined location, and there is almost no chance of contamination due to manual contact.
