Description

Method of removing asbestos

The present invention relates to a method for removing asbestos such as a ceiling, indoor and outdoor text, slate, night light, cubicle, gasket and the like.

Asbestos is inexpensive, has excellent bonding strength with other materials, has excellent mechanical strength, is excellent in nonflammability, durability, insulation, and warmth, and is widely used as a building material, especially as a finishing material.

For example, a building such as an office is usually constructed by fixing a whitewash, called "tex", asbestos tex, made by compressing pulp, cement, gypsum, etc., to a ceiling structure with bolts or screws. Therefore, when removing the asbestos tex on the ceiling of a building, it is necessary to remove a plurality of bolts or screws securing the asbestos tex.

However, when asbestos dust generated during asbestos texting is inhaled for a long time, it is known to induce asbestosis (lung scarring) and lung cancer.

Therefore, many workers who handle asbestos are exposed to asbestos or die of lung cancer. In particular, when demolishing buildings, asbestos dust can cause serious problems to workers' health, and disposal of demolished asbestos also requires caution.

Due to these problems, work in demolition of asbestos is restricted by laws. In particular, the "Regulations on Occupational Health" (No. 308 of the Labor Ordinance) should isolate asbestos-use places from other work places (Article 227) and maintain moisture during work (Article 231 ), Dismantling and dismantling asbestos should be closed, wetted, and maintained at a negative pressure (Article 239). Waste should be disposed of in an impermeable container or bag, etc. Article 240), and to prevent asbestos dust from spreading (Article 241).

Therefore, in the conventional method of removing asbestos tex according to the related art, a demolition room, a bathroom room, and a work clothes changing room are installed at the entrance of the demolition zone, and a worker removes the dust- So that the asbestos-tex-removal process can be carried out.

In the conventional method for removing asbestos tex, an operator uses an electric screwdriver to remove a bolt or a screw for fixing asbestos tex to remove a large amount of asbestos tex on the ceiling of a building. However, there is a problem that removing the asbestos tex by loosening the bolt or screw is difficult and takes a long time.

To solve this problem, a tool such as a hammer or paruru can be used to blow off asbestos-tex. However, in this case, since asbestos tex is broken, many asbestos dusts are generated and directly exposed to the operator, so that it is impossible to completely block the dust with only the conventional dustproof clothing and gas mask.

Accordingly, there is a demand for a dismantling method capable of quickly and safely removing asbestos such as asbestos texting on a ceiling of a building.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to easily and quickly remove asbestos-containing materials such as asbestos-containing materials such as many asbestos tiles in a building ceiling and slats, night lights, cubicles, gaskets, Which can minimize the scattering of asbestos dust affecting the health of the asbestos.

According to an aspect of the present invention, there is provided an asbestos dismantling method comprising:

Fixing the edges of the ceiling vinyl-preserving agent so that the plurality of asbestos-dyed texts can be covered on the ceiling of the building with a plurality of asbestos texts;

As shown in FIG. 1, a plurality of asbestos texas 10 are installed in a ceiling 3 of a building 1. As shown in FIG. At this time, asbestos tex 10 is fixed to the ceiling structure 4 (see Fig. 4) by a plurality of fastening members 11 such as bolts or screws.

Before installing the ceiling vinyl aqua regulant 20 on the ceiling 3, the air-conditioning and lighting in the work area where the asbestos tex 10 is to be removed is sealed.

Then, the window 6, the inner wall 5, and the bottom 7 of the building 1 are airtightly closed using a plasticizing agent. For reference, in FIG. 1, the veneering agent provided on the window 6, the inner wall 5, and the bottom 7 is not shown for convenience of illustration.

The operator installs the ceiling vinyl prescelain agent 20 on the ceiling 3 so as to cover the plurality of asbestos texas 10 of the ceiling 3 as shown in Fig. FIG. 2 is a bottom perspective view showing a state in which a ceiling vinyl preserver is installed so as to cover the ceiling asbestos tex of FIG. 1;

The ceiling vinyl aquantizer 20 is installed as close as possible to the asbestos tex 10 of the ceiling 3 and the rim or edge of the ceiling vinyl aquantizer 20 is fixed to the upper end of the inner wall 5 with a fixing member 21 . Before spraying the edge of the ceiling vinyl aquantizer 20 on the inner wall 5, the scattering dust remover is sprayed on the inner surface of the ceiling vinyl preserver 20, that is, the surface facing the ceiling 3. Alternatively, the scattered dust removing liquid can be sprayed on the ceiling 3 to be covered with the ceiling vinyl preserver 20. Next, the rim of the ceiling vinyl preserver 20 is fixed with a fixing member 21, for example, a tape as shown in Fig. 1 and 2 show only a part of the two inner walls 5 and the bottom 7 to clearly show the asbestos tex 10 of the ceiling 3 but the ceiling 3 has four inner walls 5, Lt; / RTI > 2, the veneering agent provided on the window 6, the inner wall 5, and the bottom 7 of the building 1 is not shown for convenience of illustration.

The ceiling vinyl preserver 20 can be fixed with another fixing member 30 such as Fig. 3 in addition to the tape.

FIG. 3 is a partial cross-sectional view showing a case where a ceiling vinyl preserver covering ceiling texels is fixed with a fixing member.

Referring to FIG. 3, the fixing member 30 may include a plurality of corner fixing portions 31 and a plurality of balls 35.

The corner fixing portion 31 is provided so as to come into contact with or close to the ceiling 3 in the corner of the interior of the building 1. Therefore, in the case of a rectangular room, four corner fixing portions 31 are used for fixing the ceiling vinyl preserver 20. That is, four corner fixing portions 31 are provided at four corners of a room of a building. The corner fixing part 31 is formed as a triangular block having a section of a right triangle and a fixing groove 32 for fixing the ball 35 on both sides of the triangular block 31 may be provided. The fixing groove 32 is formed in a shape corresponding to a part of both ends of the jaw 35. At the hypotenuse of the triangular block 31, a support member 33 for supporting the triangular block 31 with respect to the corner of the inner wall 5 is provided. The support member 33 is mounted on the bottom surface 7 and supports the triangular block 31 so that the triangular block 31 is fixed to the corner of the inner wall 5. [ The support member 33 is formed so as to be adjustable in length so as to adjust the position of the triangular block 31 according to the height of the ceiling 3. [

The mortar 35 is formed in a thin rod shape and is fixed by two adjacent corner fixing portions 31 to fix one side edge of the ceiling vinyl aqua regulant 20 to the inner wall 5 to form a ceiling vinyl- So as to maintain a state in which it is in close contact with the ceiling (3). When the both ends of the jaw 35 are positioned in the fixing grooves 32 of the two corner fixing portions 31 and the two corner fixing portions 31 are fixed by the supporting member 33, 5). That is to say, the edge of one side of the ceiling vinyl preserver 20 is placed on the inner wall 5, the ceiling vinyl preserver 20 is pressed on the ceiling 35 and both ends of the ceiling 35 are fixed to the two corner fixing portions 31 The ceiling vinyl preserver 20 is fixed to the inner wall 5 so that the ceiling vinyl preserver 20 is in close contact with the asbestos tex 10 of the ceiling 3. [

Therefore, in the case of a room having a rectangular cross section, the ceiling vinyl preserver 20 can be fixed to the rectangular ceiling 3 by using four rods 35 and four corner fixing portions 31. [

Next, as shown in FIG. 4, the operator applies an impact to the fixing portions of a plurality of asbestos texas 10 provided on the ceiling 3 from the outside of the ceiling vinyl preserver 20 covered with a plurality of asbestos texas To remove the asbestos-free tex 10. Here, FIG. 4 is a view showing a state where a fixing part of asbestos-covered veneer covered with a ceiling vinyl-promoting agent is hit by a hammer as shown in FIG.

4, the operator strikes the hammer against the outer portion of the ceiling vinyl preserver 20, that is, below the ceiling vinyl preserver 20 and toward the asbestos tex 10 of the ceiling 3. At this time, the hammer 50 may be formed in the shape of a hollow pipe at one end 51 thereof. The hole of one end of the pipe 51 hits around the bolt or the screw 11 of the asbestos tex 10 so that the screw or the bolt 11 for fixing the asbestos tex 10 to the ceiling is inserted, Is separated from the asbestos tex 10 while being fixed to the fixing structure 4 of the ceiling 3 and drops onto the ceiling vinyl preserver 20. [ At this time, since the ceiling vinyl preserver 20 is installed between the operator and the separated asbestos tex 10, and the ceiling vinyl preserver 20 is coated with the scattering dust remover, the asbestos tex 10 is prevented by the hammer 50 Even if asbestos dust is generated while being separated, the asbestos dust is blocked by the ceiling vinyl preserver 20 and does not directly affect the worker.

Alternatively, a conventional rubber hammer or rod can be used to blow off the screws or bolts 11 of the asbestos tex 10 to separate the asbestos tex 10. For example, when the rubber hammer strikes the periphery of the screw 11 of the asbestos tex 10, the asbestos tex 10 separates from the screw 11 and drops onto the ceiling vinyl preserver 20.

When the asbestos tex 10 of the ceiling 3 covered with the ceiling vinyl preserver 20 is struck with the hammer 50 with the ceiling vinyl preserver 20 interposed therebetween, The asbestos tex 20 is separated from the ceiling 3 and placed on the ceiling vinyl preserver 20. The asbestos tex 10 of the ceiling 3 covered with the ceiling vinyl preserver 20 continues to strike the asbestos tex 10 until all the asbestos tex 10 is separated.

The ceiling vinyl aqua regulant 20 may be made of transparent or semitransparent vinyl which shows the fixing region of the asbestos tex 10 so that the ceiling vinyl aquantizer 20 can be hitting the asbestos tex 10 of the ceiling 3. [ . In addition, it is preferable to use a certain thickness of vinyl so as not to damage the ceiling vinyl preserver 20 when hitting with the hammer 50. For example, the ceiling vinyl preserver 20 may use vinyl having a thickness of 4 mm or more.

When the asbestos tex 10 is hammered and separated, the worker pulls the central portion of the ceiling vinyl preserver 20 downward, and a plurality of separated asbestos texes 10 are removed from the ceiling vinyl prescription agent 20 Collect them in the center. At this time, when the vacuum adsorber 60 is attached to the central portion of the ceiling vinyl aqua regulant 20, it is easy to pull down the central portion of the ceiling vinyl preseverant 20.

In order to completely lower the ceiling vinegar aquifer 20 to the floor, it is necessary to loosen the edges of the fixed ceiling vinegar aquifer 20. That is, when the edge of the ceiling vinyl aquantizer 20 is released while pulling down the central portion of the ceiling vinyl aquantizer 20, the ceiling vinyl aquantizer 20, in which a plurality of separated asbestos texes 10 are gathered, 7).

Thereafter, the operator binds the edges of the ceiling vinyl preserver 20 and seals the plurality of separated asbestos texas 10 so that they are not exposed to the outside. At this time, when the size of the ceiling vinyl aqua regulant 20 is too large, the ceiling vinyl aqua regulant 20 can be cut only to cover and seal a plurality of separated asbestos tex 10. Alternatively, when the amount of the plurality of separated asbestos texas 10 is large, the asbestos tex 10 and the ceiling vinyl aquantizer 20 may be separated and cut to such an extent that they can be put in a waste standard envelope.

As another example, a portable bogie 70 may be used as shown in Figures 5 and 6 to facilitate the sealing and movement of the separate asbestos tex 10.

In addition, the ceiling vinyl preserver accommodating portion 71 may be formed in such a shape that only the lower surface 73 is closed and all of the four side walls are open. That is, the ceiling vinyl preserver accommodating portion 71 may be formed in the shape of a rectangular parallelepiped with only a rim or a pipe, or may be formed in a shape in which only the bottom surface 73 is covered with a flat plate.

The size of the ceiling vinyl-weaning agent receptacle 71 may be sized to accommodate both the separate asbestos tex 10 and the ceiling vinyl-preservative 20. If necessary, the height of the ceiling vinyl preserver accommodating portion 71 may be adjusted so as to increase the capacity of the ceiling vinyl preserver accommodating portion 71.

In addition, a plurality of wheels 75 are provided under the ceiling vinyl preserver accommodating portion 71. In addition, a brake (not shown) capable of fixing a plurality of wheels 75 may be provided on one side of the plurality of wheels 75. The structures of the plurality of wheels 75 and the brakes can be those of the prior art, and a detailed description thereof will be omitted. The portable truck 70 is provided with a plurality of wheels 75 so that the operator can freely move the portable truck 70 to an arbitrary position and use the brake to move the ceiling vinyl preserver 20 to a portable The bogie 70 can be fixed.

For example, after the portable truck 70 is positioned below the central portion of the ceiling vinyl preserver 20 as shown in Fig. 5, the brakes of the wheels 75 may be operated to fix the portable truck 70. Fig. In this state, when the edge 20a of the ceiling vinyl aquantizer 20 is loosened while pulling the vacuum adsorber 60 at the center portion downward, the ceiling vinyl aqua regulant 20 descends and the lower surface of the ceiling vinyl aquantizer 20 Comes into contact with the upper end 74 of the ceiling vinyl-containing agent accommodating portion 71 of the portable truck 70.

At this time, when the vacuum adsorber 60 is separated from the bottom surface of the ceiling vinyl aquantizing agent 20, the ceiling vinyl aquantizing agent 20 is separated by the weight of the separated asbestos tex 10 collected at the central portion of the ceiling vinyl aquantizing agent 20 And enters the inside 72 of the ceiling vinyl preserver accommodating portion 71 as shown in FIG. 6 while accommodating the asbestos tex 10. At this time, since the vicinity of the edge 21a of the ceiling vinyl preserver 20 is supported by the edge of the upper end 74 of the ceiling vinyl preserver holding portion 71, the edge 20a of the ceiling vinyl preserver 20 is bundled and sealed It is easy.

When the sealing of the ceiling vinyl preserver 20 is completed, the operator can push the portable truck 70 to load the ceiling vinyl preserver 20 which seals the separated asbestos tex 10 at the designated place.
