Description

Noise control device for electrical plumbing {Acoustical sound enclosure for electric wiring}

The present invention relates to a noise prevention device for electrical piping, and more specifically, installed in the lower part of the electrical piping box embedded in the wall slab of the building, the sound flowing from the outside of the building propagated through the wire piping box and wire wiring piping. The present invention relates to a noise preventing device for electric piping that can effectively block noise propagating in an interior of a building.

In general, in the electrical construction of buildings, such as buildings or apartments, electrical plumbing construction is an important process is a construction that must be carried out in parallel or subsequent work according to the construction process quickly and accurately. Therefore, in order to minimize the reconstruction of the building, it is necessary to review the electrical, architectural, and mechanical drawings before construction, to accurately prepare the construction drawings, and to secure the materials with sufficient margins. In addition, the electrical plumbing work has a significant effect on the quality of the building work, so it must be a good construction.

The urban concentration, densification and increased traffic volume of the population due to industrial developments and changes in social structure, which have been going on in the past, have brought about sudden changes in lifestyle and pollution. Among these, noise not only has a direct effect on humans such as sensory damage, disturbing hearing or hearing loss, but also can cause emotional damage, disturbances in sleep, recreation and work. Such noise pollution is a sensory pollution and has the essence which cannot be solved simply physically or chemically such as air pollution or water pollution. In particular, the increasingly serious noise and vibration pollution is not only unpleasant to humans, but also causes enormous damage to building structures and mechanical structures, and the resulting disputes are constantly being raised.

1 is a cross-sectional view for explaining a noise preventing material installed in a conventional electrical piping box, Figure 2 is an enlarged cross-sectional view of the 'A' portion of FIG.

1 and 2, generally, the electrical plumbing boxes 10 and 15 are positioned at a predetermined height from a floor 20 of a building such as an office, a room, or a living room such as an apartment. Is embedded in the slab (30).

The electrical pipe boxes 10 and 15 may be configured to draw out the wires 50 through the wiring pipes 35, 40, and 45 for wiring the boxes 10 and 15 for the electrical pipes, respectively. It is formed, it is used to electrically connect the lighting fixtures, wiring apparatus to various electrical appliances to the boxes for the electrical pipe (10, 15).

After installing the electrical pipe boxes 10 and 15, a device such as an outlet is mounted on the front surface of the electrical pipe boxes 10 and 15 to connect and use various electrical devices. However, in the interior of the wiring pipes 30, 40, and 45 through which the wires 50 pass, there is a redundancy except for the space occupied by the wires 50 so as to easily accommodate the wires 50. A space is provided, along with the interior space of the wiring pipes 30, 40, 45, various noises inside the building or various noises flowing from the outside of the building propagate to the adjacent building or another space of the same building. There is a problem.

In order to solve the above-mentioned problem, at present, by inserting a noise preventing material 55 such as a sponge or rubber into the wiring pipe 35, 40, 45 connected to the lower portion of the electrical pipe boxes 10, 15, wiring pipe A method of blocking noise inside and outside the building that propagates along (35, 40, 45) is used.

However, the noise preventing material installed in the above-described conventional electrical piping box has some problems as follows.

First, since the conventional noise suppression material is simply inserted into the wiring pipe while crimping the wires in the wiring pipe with a strong force on a material such as a sponge or rubber having an arbitrary shape, there is a high possibility of causing a poor electrical connection of the wires. In addition, it is difficult to completely fill the space in which noise propagates inside the wiring piping. Therefore, even when the noise prevention material described above is inserted into the wiring pipe, the sound is still propagated along the box for the electrical pipe and the wiring pipe because perfect sound insulation is difficult, and this phenomenon is more prominent especially when the surroundings are quiet.

In addition, the process of inserting the noise preventing material into the wiring pipe can be performed to some extent, but it is inconvenient to remove the noise preventing material inserted into the wiring pipe in the case of replacing the electric wire or replacing the box for the electric pipe. There is an accompanying problem.

The present invention in order to solve the problems of the conventional noise prevention material for electrical pipes described above is an object of the present invention is installed in the lower portion of the electrical pipe box to completely enclose the space in the wiring piping, the electrical piping box and wiring piping It is to provide a noise preventing device for electrical piping that can completely block the noise inside and outside the building propagated through.

Another object of the present invention is to provide a plurality of wire receiving holes for the electrical pipes that can be easily drawn out and installed in the wiring pipes and at the same time having a fixing member fastened to the box for electrical pipes, easy installation and removal It is to provide a noise prevention device.
