Description

  The present invention relates to a dust collector for building demolition.

When dismantling a high-rise building, there is a case where a dismantling method with the dismantling space closed is used to reduce noise and dust to the surroundings and to prevent falling, but this occurs in the closed working space. There is almost no countermeasure against suspended dust.
As one of the closed-type dismantling methods, for example, Patent Document 1 discloses an outer body installed on the outside of a building, an inner body arranged on the inner side thereof, a sheet-like member arranged on the inner side, and a negative member. A dismantling device comprising a pressure dust removal device is disclosed.

  However, in the closed-type dismantling method, when there are few openings in the internal work space, dust floats in the work space, and the work environment may be deteriorated due to the dust.

  An object of the present invention is to collect dust generated at the time of dismantling a closed type building and collect it easily so that it can be easily discarded.

In order to solve the above problems, the invention described in claim 1
It has a ceiling part and a peripheral wall part that cover the work space above the demolished building,
Forming a dust collection space in which dust generated in the work space is collected, with the peripheral wall portion having an inner / outer double structure,
It is characterized by a dust collection device for building dismantling provided with an adsorbent for adsorbing the collected dust at the bottom of the dust collection space.

The invention described in claim 2
A dust collector for building demolition according to claim 1,
A sprayer that sprays the dust collection space to drop the dust is provided.

The invention according to claim 3
The dust collector for building demolition according to claim 1 or 2,
A dust collection suction pipe is provided which opens to the work space and sucks dust, and opens the dust collection space to discharge the sucked dust.

The invention according to claim 4
A dust collector for building demolition according to any one of claims 1 to 3,
A grating floor is provided above the adsorbent in the dust collection space.

  According to the present invention, at the time of dismantling a closed type building, the dust generated in the work space can be collected in the dust collection space and then adsorbed to the adsorbent and easily discarded.

It is a longitudinal cross-sectional view which shows schematic structure of one Embodiment of the dust collector for building demolition to which this invention is applied. It is an enlarged view of the inner and outer double structure part of FIG.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
(Embodiment)
FIG. 1 shows a schematic configuration of an embodiment of a dust collection apparatus for building demolition to which the present invention is applied. 1 is a demolition building, 2 is a work space, 3 is a ceiling portion, 4 is a peripheral wall portion, and 5 is dust collection. A space 6 is a dust collection suction pipe.

  As shown in the figure, a ceiling part 3 and a peripheral wall part 4 that are assembled with steel and cover a work space 2 for dismantling work above the demolishing building 1 and covered with a panel are provided. A double double skin structure is used, and a dust collection space 5 is formed in the double skin structure.

A dust collection suction pipe 6 is provided below the ceiling portion 3.
As shown by the arrows, the dust collection suction pipe 6 is opened at a plurality of locations in the work space 2, sucks dust such as concrete and interior materials floating in the air by dismantling, and sucks the sucked dust. It opens into the dust collection space 5 in the double skin structure part of the surrounding wall part 4, and discharges | emits it.
Specifically, dust is collected in the dust collection space 5 in the double skin structure part by a device for controlling the airflow in the closed work space 2 or by natural ventilation (a difference in height of the locally provided opening).

  FIG. 2 is an enlarged view of the inner / outer double structure, 7 is a sprayer, 8 is an adsorbent, 9 is a grating bed, and d is dust.

  As shown in the figure, in the dust collection space 5 in the double skin structure part, a plurality of sprayers 7 are installed under the ceiling, while an adsorbent 8 is installed on the entire bottom surface, and a grating is formed on the entire surface above the adsorbent 8. Floor 9 is installed.

The sprayer 7 sprays mist or solidified material.
The adsorbing material 8 has a function of adsorbing the dust d and is, for example, a block-like material partitioned by installing a partition plate (not shown), and can be taken out in units of blocks after the dust d is adsorbed.
The grating floor 9 drops the dust d onto the lower adsorbent 8 through the lattice gap.

  Thus, in the dust collection space 5 having the double skin structure, the mist or the solidified material is sprayed by the sprayer 7, the dust d adhering to the mist or the solidified material is lowered and adsorbed to the adsorbent 8, and the adsorbed dust d is integrated into the adsorbent 8 and hardened.

  In the above, the ceiling part 3 and the peripheral wall part 4 that cover the work space 2 on the demolition building 1 are lowered along the demolition building 1 in accordance with the progress of the building demolition. It also functions as an external scaffold with the door not opened and the worker entering the dust collection space 5 and resting on the grating floor 9.

As described above, according to the building demolition dust collector of the embodiment, the ceiling portion 3 and the peripheral wall portion 4 that cover the work space 2 on the demolition building 1 are provided, and the peripheral wall portion 4 has an internal / external double skin structure. In the double skin structure, a dust collection space 5 is formed in which dust d generated in the work space 2 and floating in the air is collected, and an adsorbent 8 that adsorbs the dust d collected at the bottom of the dust collection space 2. Is provided.
Therefore, when the closed building is dismantled, the dust d generated in the work space 2 and floating in the air is collected from the ceiling portion 3 into the dust collection space 5 of the peripheral wall portion 4 and adsorbed to the bottom adsorbent 8, and the adsorption It is possible to easily dispose of the collected dust d in a state of being solidified integrally with the adsorbent 8.

  Specifically, the dust collection pipe 6 provided under the ceiling of the work space 2 sucks the dust d floating in the air, and opens the sucked dust d to the dust collection space 5. The mist or solidified material is sprayed by a plurality of sprayers 7 provided under the ceiling of the dust collection space 5 and the dust d is dropped, so that the dust d to which the mist or solidified material adheres is adsorbed 8 at the bottom. So that the adsorbed dust d can be solidified integrally with the adsorbent 8.

  Then, the adsorbent 8 in a state where the dust d is solidified can be discarded together. In particular, by using the block-shaped adsorbing material 8 partitioned by the installation of the partition plate, after adsorbing and solidifying the dust d, the adsorbing material 8 can be taken out in units of blocks and can be easily disposed of one after another.

  Moreover, the ceiling part 3 and the peripheral wall part 4 which cover the working space 2 on the demolished building 1 and descend along the demolished building 1 according to the progress of the demolishing of the building are separated into a dust collection space in the double skin structure part of the peripheral wall part 4. It can also be used as an external lifting scaffold in a state where an operator is placed on the grating floor 9 provided above the adsorbent 8 at the bottom of 5.

(Modification)
Needless to say, in addition to the above-described embodiments, specific detailed structures and the like can be changed as appropriate.
