The present invention relates to a sealed electric cable tray for shielding electromagnetic waves of a multi-family house, and more particularly, to block electromagnetic waves so that electromagnetic waves generated from a cable installed in the multi-family house do not affect surrounding people, The present invention relates to a sealed electrical cable tray for electromagnetic shielding of a multi-unit house, which is configured to be sealed to prevent other dust from entering and accumulating.

In multi-unit houses such as apartment complexes, many cables, such as power lines and communication lines, are installed. Such cables are usually wired to the basement floor of a building. In this case, if the cable is routed in the air, it is not only sag down due to its own load, but also there is a high risk of interference with other structures.

Therefore, generally, the structure which supports a cable by mounting the tray which accommodates the said cable to the hanger provided under the slab is used. Such a hanger is a horizontal member coupled to the lower portion of the rod-shaped member, it is common to combine with a bolt and nut.

However, such a structure is very troublesome in the case of a large number of hangers because it is necessary to loosen the combined bolts and nuts to change the position of the horizontal member when adjusting the position of the received cable or checking, repairing or replacing the cable. There was a problem.

Accordingly, the cable is generally supported by using a metal tray having appropriate structural strength. The tray has a substantially ladder-like configuration connected at regular intervals by a plurality of rungs for binding cables to the lower ends of two side beams arranged in parallel to each other. It is supported horizontally on the wall or ceiling by a hanger.

In order to prevent the cable from being damaged by falling foreign matter or rainwater from above, the cable is covered with an upper opening of the tray to protect the cable.

In the conventional cable support structure, as shown in Figs. 1 and 2, the bottom of the plurality of hangers (1) fixed to the ceiling fixed the frame 2 with a nut up and down, the lower portion of the frame 2 It was common to insert the steel pipe 7 into the tooth groove 3 formed in the fixed groove with the u-bolt 5 and the nut 6.

Since the cable is protected by inserting the cable inside the steel pipe 7 and the steel pipe 7 is fixed by the u-bolt 5, the cable is protected.

In buildings of multi-unit houses, since electric power or communication cable is installed on the ceiling inside the underground parking lot, there is a problem that electromagnetic waves are generated to adversely affect the pedestrians passing below.

The adverse effects of these electromagnetic waves on the human body have generally been known to cause abnormalities in the immune system. High intensity electromagnetic waves cause electric current to flow through the human body, and prolonged exposure to electromagnetic waves can affect the flow of ions in the cell membrane, causing hormone secretion and abnormalities in the immune system.

And it is known that skin trouble occurs. The electric field flows through the skin, so if you use the computer a lot, it is more likely to cause skin problems such as eczema, and it is dangerous because it is fatal to tissues such as blood cells, genital organs and lymph nodes, etc., which have rapid cell proliferation.

Electromagnetic waves are known to interfere with sound sleep. In other words, electromagnetic waves reduce sleep-related melatonin hormones, which interfere with sleep and cause drowsiness, insomnia, and nervousness, as well as promote aging.

Electromagnetic waves are also very harmful to pregnant women and infants, so if exposed to prolonged exposure, pregnant women are at increased risk of miscarriage or birth defects. Growing children may also be more vulnerable to electromagnetic waves due to their weak immunity.

Therefore, the cable tray must be structured to block harmful electromagnetic waves from reaching the human body.

And there is no cover in the case of supporting the cable in such a steel pipe structure, in this case dust or other foreign matter is stacked on top, if there is a spark or the like in this state, there is a risk of fire.

The present invention has been made in order to solve the problems as described above, when the steel pipe is passed through the cable is installed on the hanger to seal the upper and lower parts of the steel pipe to prevent dust or foreign substances from entering, and is generated by surrounding the steel pipe with a copper plate to ground Enclosed electric cable tray for electromagnetic wave shielding of apartment houses where electromagnetic wave shielding effect is increased by installing multi-stage blocking plate installed in the lower part of steel pipe which is easy to reach human body by preventing electromagnetic waves from reaching people. The purpose is to provide.

In order to achieve the above object, the present invention inserts an O-ring on a hanger for contacting the bottom surface of the upper copper plate to support the upper copper plate at an arbitrary height, and the second and third lower portions below the first lower copper plate with spacers therebetween. The copper plates are spaced apart and stacked, and a hanger hole for inserting a hanger is formed in the center of the spacer and the first, second, and third lower copper plates, and the upper and third lower copper plates of the first lower copper plate are formed by a nut screwed into the hanger. Pressing the bottom surface, the bent groove is inserted into the fixing groove formed in the upper copper plate to form an inclined portion by bending both ends of the first, second and third lower copper plate upward, bent 90 degrees at the end of each inclined portion, The protrusion having a groove is formed on the outer side of the connecting rubber, and three fixing grooves having locking jaws for fitting the bent ends formed on both side ends of the first, second, and third lower copper plates are formed on the inner side of the connecting rubber.
