Description

The dust-proof scattering module and the anti-dust scattering screen fence for the demolition of a building

The present invention relates to a screening technology for building dismantling, and more specifically, a dust scattering prevention masking module having a structure capable of preventing dust scattering generated when dismantling a slab and a wall of a concrete building, and for dismantling a building including the module It is related to the dust scattering prevention screen.

In recent years, as the city regeneration project has been actively conducted, many works have been done to dismantle old buildings and then build new buildings again or dismantle only certain parts of buildings. There are various methods of dismantling existing buildings, but in the process of dismantling, most processes inevitably cause noise and generate dust.

In addition, since concrete debris generated during dismantling of buildings may damage surrounding buildings, pedestrians, vehicles, etc., dismantling is a task that requires very careful attention.

Moreover, if the buildings to be dismantled are located in a downtown area or a residential area, the surrounding buildings are damaged due to noise and dust generated during the dismantling of the building, and complaints are generated to act as a cause of air delay.

Therefore, in order to prevent dust and building debris from damaging nearby buildings or people, a shielding screen is usually installed around the building to dismantle it, but debris or noise leaks out, and the screening is completely enclosed. There was a hassle that had to be installed in front of the demolished building.

In order to solve this problem, in recent years, only the upper layer of a high-rise building is installed and dismantled, and then the steps of dismantling and moving the screen to the upper level of the car located below are sequentially applied to remove the high-rise building. Methods have been proposed in which the function of the shielding membrane structure is enhanced to shorten and minimize the occurrence of noise and dust. Among these technologies, in Korean Patent Registration No. 10-1027860 (name: eco-friendly automatic building dismantling method and structure for building dismantling), installing a first support projecting out of the building; Installing a support pillar and a side disassembly film on an upper portion of the first support, and installing a guide beam movable in the vertical direction on the support pillar or the side disassembly film; Dismantling the part of the building surrounded by the side dismantling film, and then installing a second support under the first support; Moving the guide beam downward to mount the lower side of the guide beam on the second support; Removing the first support from the building; And moving the support column and the side dismantling film downward to mount the second support; and includes a method of dismantling a building that repeatedly performs the above steps in accordance with the height of a high-rise building to be demolished. .

However, the above patent adopts a structure that covers both the side and the top of the floor to be dismantled in the building with a covering film for dismantling, and the dynamic relationship between the structures is complicated, and the top dismantling film cannot balance power due to wind, etc. In the case, there is a problem in that the stability of the dismantling structure is deteriorated as a whole, so it is necessary to develop a technology capable of solving it.

Next, the dust scattering prevention shielding film 1 for dismantling a building of the present invention includes a plurality of dust scattering preventing shielding modules 100 having a structure as shown in FIGS. 1A to 1G, as illustrated in FIGS. 2 to 5 As can be installed so as to surround only the demolished construction layer of the building to be dismantled. Therefore, the dust scattering prevention screening film 1 for dismantling a building of the present invention includes a certain number of dust scattering prevention screening modules 100 according to the width and shape of the building, where the dust scattering prevention section 120 and the side screening section The 130 and the bottom cover 140 may be composed of only modules, for example, 7.5 m in length, all of which have the same overall length, but if necessary, a module of 5.5 m, a module of 6 m, and a module of 8 m according to the length of the building. It is also possible to configure the dust scattering prevention covering film 1 for dismantling the building of the present invention to have a different length for each module, including.

Referring to FIG. 4, which is a side schematic diagram showing the principle in which dust is controlled when dismantling a building in a state in which the dust scattering prevention barrier film 1 for building disassembly of the present invention configured as described above is installed in a building to be dismantled, the dust for dismantling the building of the present invention Among the dusts generated during demolition construction with the shatterproof screen 1 installed, the dust rising vertically as in ① is sprayed from the sprinkler member 124 of the dust scatter prevention unit 120 installed at least 1 m higher than the demolition construction layer. The dust is collected and dropped by the droplets of water that are sprayed out like fog, and the scattered dust that is scattered sideways by water pressure as shown in ② will purify the air installed to cover the frame member 121 installed obliquely toward the dismantling building. It can be seen that while passing through the filter member 122, dust is removed and only the purified air escapes.

Therefore, the dust scattering prevention barrier film 1 for dismantling a building of the present invention can be controlled by adjusting the water pressure of water according to the speed of the air inhaled by the equipment or suddenly generated dust by equipment when dismantling the wall or slab. Rather, it is dispersed in all directions by water pressure, and the air that sucks in dust is pushed to the side as in ② and rises along the screen, so that it naturally passes through the air purifying filter member and scatters with purified air.

As shown in FIG. 5, the dust scattering prevention screen 1 for dismantling a building of the present invention is constructed by installing a dust scattering prevention unit at a position at least 1 m higher than the demolition target layer of the demolition target building. Because the surrounding structure can remove dust generated during demolition, the installation is easy and simple, and the stability of the dismantling structure is improved overall by simplifying and lightening the components, so it can be safely and conveniently used during building dismantling.

The present invention has been shown and described with reference to preferred embodiments, as described above, but is not limited to the above-described embodiments, and to those skilled in the art to which the present invention pertains without departing from the spirit of the present invention. By doing so, various changes and modifications will be possible.
