Description

{Apparatus of protection fire spread using cable support tray}

The present invention relates to a fire spreading prevention structure of a cable support tray installed in a multi-family house, and more specifically, when a fire occurs in a cable located in a cable support tray installed in a multi-family house, the fire burns the sheath of the cable. It prevents the spread, fire transmission through the cable disappears within a certain period to prevent secondary disasters, and cable damage due to the fire is limited to a certain section, so there is no need to replace the cable as a whole. It relates to a fire spreading prevention structure of the cable support tray is installed in the apartment house made easy.

Generally, wiring insulators are installed on ceilings and walls to wire electric wires in factories, warehouses, basements, parking lots, etc., but the wires are fixed when wiring cables. As the electric wiring is installed by tying and fixing the wires, the electric wires are tangled in a disorderly manner in the pipe or rope, and there is a danger of fire because of the bending of the wires. There was a problem that the handling and management of electric wires were difficult.

In general, many cables, such as power lines and communication lines, are installed in buildings, large apartment complexes, or factories in urban areas. Such cables are usually wired along underground ceilings or ceilings or walls of buildings. At this time, the cable is not only drastically droops down due to its own load, but also interferes with other structures, causing high damage, and hurting aesthetics.

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.

A cable support tray for supporting a cable installed in a conventional apartment house has a threaded portion formed at a lower end of two hangers fixed to the ceiling, and fixed with a nut by passing a square pipe through the threaded portion, and a cable support tray on the square pipe. Is fixed.

The cable placed in the cable support tray may be ignited by a fire caused by leakage of electricity, fire by carbonization of an organic insulator, fire due to overheating of a connection part, and a temperature increase due to multi-line laying.

In addition to these causes of fire, if a fire occurs for a variety of reasons, the sheath of the cable is made of a material that burns well and is quickly transferred over the cable. Insulation or sheathing of the cable is a polymer material that is decomposed by heat and causes secondary disasters due to toxic and corrosive smoke during combustion. Therefore, cable sheathing should be used as a flame retardant material to prevent combustion. It is desirable to install a prevention device but it is not.

Insulation or sheathing of the cable is a polymer material, and the hydrogen chloride gas generated during the combustion of the cable is harmful to the human body due to the strong toxicity of corrosive metals and respirators.

The cable burns quickly after a fire, not only knows its fire point, but also produces fumes, corrosive and toxic gases.

Even if sufficient measures are taken, unexpected cable fires may occur due to changes in the situation or unforeseen accidents. If a fire occurs, the direct damage, as well as the secondary disaster or social impact, will be greatly increased.

The present invention is to solve the problems as described above, when a fire occurs in the cable located in the cable support tray installed in the apartment house to prevent the fire spreads while burning the sheath of the cable, the fire transmission through the cable It disappears within a certain period to prevent secondary disasters in advance. Cable damage due to fire is limited to a certain period, so that the cable does not need to be replaced as a whole. Its purpose is to provide a fire spreading protection structure.

In order to achieve the above object, the present invention is a cable support guided by the cable is seated on the upper surface of the support bar in a state in which both ends of the support bar are fixedly supported by the left and right U-shaped side frames spaced apart from the ceiling by the hanger, respectively. In a tray;

The vertical surface of the left and right U-shaped side frames positioned between the support bars of the cable support tray is formed with a downward protrusion protruding in an inverted triangle to the bottom, and both ends of the weight rollers are axially coupled upward and downward in the center of the downward protrusion. A weight roller long hole is seated on an upper surface of the cable to press down on the support bar by its own weight, and left and right vertical holes are formed on left and right sides of the weight long hole;

The left and right side plates are respectively located on the outer side of the downward projection of the left and right U-side frame is axially coupled to the left and right vertical holes by the shaft bar, and the fixing ring is formed on one side of the upper and left side plates. In the upper center of the plate is horizontally projected outwardly is formed through-hole plate having left and right holes, the center of the left and right side plate is formed with a vertical guide bar through which the weight is penetrated, the upper and lower rings are projected on the weight surface, respectively, A lifting flameproof frame having a flameproof storage plate having a flameproof recess for receiving a gel type flameproof gel at a lower portion of the weight and fixed to the inner surface of the lower left and right sides of the weight;

One end of the wire burned by a fire is formed by a fixed end is formed on the upper and lower sides of the left and right U-side side frame frame on the left and right sides of the upper and lower sides of the frame, zigzag, The fixed and the wire is guided in a zigzag to the guide roller and the other end is penetrated through the right hole of the right and left plate through the right hole of the weight plate is fixed to the right ring of the upper surface of the weight, respectively, the weight to fix the weight at the upper end of the vertical guide bar, respectively Weight fixing frame;

The pulley is pivotally coupled to the upper end surface of the left and right U-shaped side frame on the lifting flameproof frame, and is made of a metal material which is not burned by a fire. One end is fixed to the fixing ring and the other end is wound on the pulley. It is fixed to the left ring of the weight through the left through hole of the through plate to move the lifting flame resistant frame to the upper by the weight of the weight when the wire of the front and rear side weight fixing frame is lowered by the weight roller It is characterized in that it has a left and right flameproof frame moving frame is formed of steel wire for inserting the cable pressed into the flame retardant gel.

As such, the present invention prevents the fire from spreading by burning the sheath of the cable when a fire occurs in the cable located in the cable support tray installed in the apartment house, and the fire transmission through the cable disappears within a certain period. Secondary accidents are prevented in advance, and cable damage due to fire is limited to a certain section, so that the cable does not need to be replaced as a whole, and repair is easily performed.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
