DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dismantling method for dismantling a building.

[0002]

2. Description of the Related Art In the dismantling of a structure, a scaffold is set on the periphery of the structure to be dismantled from the ground, and the scaffold is surrounded by a soundproof panel.
The method of dismantling inside is known.

[0003] However, the above technique has a problem in that since the upper part of the building to be dismantled is in an open state, dust and noise generated at the time of dismantling scatter from the upper part and cause construction pollution around the dismantling work site. A technique of disassembling the outer periphery without assembling a scaffold is disclosed in Japanese Patent Publication No. 61-10627. However, this technique relates to a tower-shaped structure made of reinforced concrete such as a chimney, which is an object to be dismantled, and cannot be used for dismantling a building such as a building.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides an all-weather non-polluting dismantling method which does not generate dust or noise in the surroundings, can be operated independently of the weather, and does not require a scaffold from the ground. It is intended to be.

[0005]

According to the present invention, there is provided a sliding-type opening / closing roof for improving the environment and for carrying in and out a demolition machine and materials, and a soundproof and dustproof shielding device is provided downward from an end of the roof. In the all-weather non-polluting demolition method of disposing and dismantling the building, the lower N of the top floor N of the building to be dismantled
Opening an opening for a mast and an opening for a hoist on the -1st floor and on the N-2 floor further below it, attaching a jack base and a jack to the opening for the mast, and fixing the mast to the opening via the jack base independently on the mast opening; On the mast, the sliding open / close roof, overhead traveling hoist,
Assembling the water sprinkling device, elevating scaffold, and the soundproof and dustproof shielding device, dismantling one floor while collecting and spraying water with the dust collecting and sprinkling device, and disassembling waste etc. on the bottom floor with the hoist. When the work is carried out and the dismantling work of one floor is completed, the mast is lowered to the lower floor by the jack and fixed, and this is sequentially repeated to dismantle the dismantled building.

[0006]

According to the all-weather non-polluting dismantling method constructed as described above, the dismantling work by the dismantling machine by the sliding openable roof and the soundproof and dustproof shielding device provided below the edge of the roof. Since the work is performed in a closed space having a dust collecting and sprinkling device, dust and noise pollution do not occur.

[0007] Demolition waste and the like are lowered by the overhead traveling hoist from the carry-out opening provided on each floor to the ground and carried out, so that noise and dust are not generated.

In addition, the work can be performed without being affected by the weather because of the openable roof. Then, the mast is installed only on the upper part of the building, and the mast and the roof body are lowered as the demolition progresses. Therefore, a mast of a certain length can be applied to a building such as a high-rise building regardless of the height, and there is no need to lay a guide rail from the ground to the upper part.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

Before describing the method of the present invention, an embodiment of an apparatus for performing the method will be described.

In FIG. 1, a slide type opening / closing roof 2 is supported by a plurality of masts 6 above a top floor 1a (N floor) of a building 1 to be demolished, and a demolishing machine 3 and a ceiling are mounted on a frame 2a of the roof. A traveling hoist 4 and a dust collecting / sprinkling device 5 are attached.

The mast 6 is a lower floor 1b of the top floor 1a.
A jack base 8 is provided in an opening provided on the (N-1 floor), and a mast 6 is attached to the jack base 8 with a lower pin 7b. The jack base 8 is provided with a plurality of jacks 7 which are climbing devices.
The mast 6 is supported on the upper part of the jack 7 by an upper pin 7a. The lower end of the mast 6 is at the lower floor 1c (N-2
Jack base 8 attached to the opening provided on the floor)
Penetrates.

At the end of the roof 2, a shutter 9 as a soundproof and dustproof shielding device having an external drop stopper 11 is attached at the lower end thereof, and a lifting scaffold 10 is provided inside. Note that the external drop stopper 11 and the shutter 9 are formed separately.

Hereinafter, the disassembly procedure will be described.

Referring to FIG. 2, first, mast openings A1, B1 and an opening C1 for a ceiling traveling hoist 4 are opened on the N-1 floor 1b, and similarly, openings A2, A2, B
2, C2 is opened, the jack base 8 and the jack 7 are attached to the openings A1, B1, and the jack base 8 is attached by reinforcing the openings A2, B2. Then, the mast 6 passes through the jack base 8 and the jack 7, and is self-fixed to the openings A1 and B1 via the lower pin 7a of the jack base 8. At this time, in the openings A2 and B2, the mast 6 penetrates through the jack base 8 as a guide.

Then, the slide roof 2 and the hoist 4, the dust collecting and sprinkling equipment 5, the elevating scaffold 10, the dustproof and the soundproof shutter 9 and the like are mounted on the mast 6, and the assembly of the entire system is completed.

The top floor 1a is dismantled by using the dismantling machine 3 and the elevating scaffold 10 while driving the dust collecting and sprinkling device 5, and the dismantling garbage and the like are removed by the hoist 4 using the openings C1, C2. Transport to lower floor and discharge.

When the outer wall is dismantled, it is safe because the external stopper 11 prevents the disassembly waste from falling.

When the disassembly of the top floor (N floor) 1a is completed,
Referring to FIG. 3, openings A3, B3 and C3 are located on the N-3 floor 1d.
And the openings A3 and B3 are reinforced and the jack base 8 is opened.
On the N-1 floor 1b, the jack 7 is extended while the lower pin 7b of the jack base 8 supports the mast 6, the upper pin 7a is inserted into the upper hole of the mast, and the lower pin 7b is removed. Lower 7 to lower mast.

This operation is repeated, and the mast 6 is lowered to a predetermined height (the lower part of the mast penetrates the jack base 8 of the openings A3, B3), and then the lower pins 7b of the jack base 8 of the openings A2, B2 are removed. Fixed to mast 6, opening A
1, the jack 7 of B1 is changed to the N-2 floor 1b, and the jack base 8 is changed to the N-5 floor.

Then, the N-1 floor 1b is dismantled.

Hereinafter, the same operation is repeated until the disassembly of the construction 1 is completed.

[0023]

The present invention is configured as described above, and has the following effects. (A) Dust and noise due to demolition work are shielded by the sliding-type open / close roof and soundproof and dustproof shielding device, and there is no need to set up a scaffold from the ground around the building, so low pollution to the external environment Can be achieved. (B) At the same time, a work environment and processes that are not affected by weather such as wind and rain can be secured. (C) The mast is installed only on the upper part of the building, and the mast and the roof body are lowered as the demolition progresses. Therefore, a mast of a certain length can be applied to a building such as a high-rise building regardless of the height, and there is no need to lay a guide rail from the ground to the upper part.
