Abstract

Disclosed is a cover for preventing diffusion of combustion of a cable tray. According to the present invention, when combustion of a cable in a cable tray occurs, an insulating flame-retardant member which was in contact with the cable starts swelling immediately to perform a flame-retardant action. Therefore, without time delay after the occurrence of combustion of the cable, the retardant action in the cable can be done immediately. Even if a cable is added to or removed from the cable tray, the insulating flame retardant member in the elastically deformed state is automatically deformed by self-restoring force depending on whether the cable is added or removed, and comes to get in the way between an upper frame member and the cable again, so it is possible to cope with the addition or removal of the cable on the cable tray without any additional work. Accordingly, there is an advantage that psychological stability concerning flame prevention can be enhanced without additional work.

Description

Cover for diffusion proof of combustion of cable tray}

The present invention relates to a cable tray combustion diffusion preventing cover.

A plurality of cables pass along the ceiling or wall of a common ward, subway, etc., which jointly accommodate underground facilities such as electricity, gas, and water supply facilities, communication facilities, and sewage facilities. The cable tray is fixed to the

In such a cable tray, combustion can be generated by a short circuit or the like, and therefore, a combustion diffusion preventing structure for the cable tray is required.

Conventionally, a method of applying a flame retardant paint to a cable tray and a cable supported on the cable tray has been applied a lot, but there is a problem that the combustion diffusion prevention is not properly achieved by applying the flame retardant paint.

Thus, as shown in the patent documents presented below, the applicant of the present application developed a structure surrounding the cable tray was completed until the patent registration.

However, according to the conventional cable tray combustion diffusion prevention structure including the patent document set forth below, the flame-retardant member for flame retardation of the cable tray is formed in the inner surface of the upper frame member, and thus the cable placed on the cable tray. And the space between the flame-retardant member and the frame becomes empty, so that even if combustion occurs in the cable, time is required until heat from such combustion is transferred to the flame-retardant member, so that combustion occurs in the cable and the There was a disadvantage in that a time delay until the flame-retardant action of the flame-retardant member was generated, so that an immediate response to the combustion generated in the cable was not possible.

In addition, according to the conventional cable tray combustion diffusion prevention structure including the patent document set forth below, in order to enhance the flame retardant effect and give psychological stability to the flame retardant, the space between the upper frame member and the cable had to be blocked, A separate cable flameproof member had to be filled in the space between the frame member and the cable. Since the cable flameproof member is manufactured separately according to the cable installed on the cable tray, the cable after the cable flameproof member is installed. When the cable is additionally installed on the tray or when a part of the cable previously installed on the cable tray is removed, an arbitrary hole is generated in the space between the upper frame member and the cable, so that an immediate flame and flame Psychological In order to improve the sense of stability, there was a problem in that a new cable flame retardant member to re-block the space between the upper frame member and the cable has to be manufactured and installed again.

It is shown in the form of a wave as a whole, but it is illustrative, and may be formed in two wave forms as in the first embodiment described above.

Long holes 238 formed long in a length direction of the upper frame member are penetrated at ends of the upper frame member in which both ends of the upper frame upper surface 231 are connected to the elastic deformation moving member 270. The elastic deformation moving member 270 may be moved along the long hole 238 while penetrating the long hole 238.

In detail, the elastic deformable moving member 270 penetrates the long hole 238 while being coupled with the isolation flame retardant member 240, and protrudes to the upper side of the upper frame upper surface 231. And an elastic deformable fixture 272 coupled to the distal end of the elastic deformable movable member 271 to prevent any detachment of the elastic deformable movable member 271.

The elastic deformable moving body 271 penetrates the long hole 238 in a state of being coupled with the isolation flame retardant member 240, and the elastic deformable fixing body 272 is fixed to a distal end of the elastic deformable moving body 271. As the elastic deformable moving object 271 is moved along the long hole 238 by an external force such as an operator, the degree of elastic deformation of the insulating flame retardant member 240 may vary.

That is, the elastically deformable moving object 271 is moved in the long hole 238, so that the elastically deformable moving body 271 is moved toward the other end of the upper frame upper surface 231 rather than the distal end to which the elastically deformable moving member 270 is connected. When the deformable moving object 271 is relatively closer to each other, the degree of elastic deformation of the insulating flame retardant member 240 becomes relatively larger, so that a part of the insulating flame retardant member 240 is not connected to the cable on the cable tray 20. It is relatively further protruded toward (10), thereby allowing the cable 10 and the insulating flame retardant member 240 to come into contact with the cable 10 is pressed further.

On the other hand, the elastic deformable moving body 271 is moved in the long hole 238 to be spaced apart from other distal ends of the distal ends of the upper frame upper surface 231 to which the elastic deformable moving member 270 is connected. When the elastically deformable moving body 271 is moved relatively further toward the other side, the degree of elastic deformation of the insulating flame retardant member 240 becomes relatively smaller, so that a part of the insulating flame retardant member 240 is formed in the cable tray. Relatively less protruding toward the cable 10 on the 20, thereby allowing the cable 10 to contact the insulating flame retardant member 240 while being relatively less pressurized.

Reference numeral 273 denotes a washer interposed between the head of the elastic deformable moving object 271 and the insulating flame retardant member 240.

Here, the elastic deformation moving member 270 has been proposed to be applied to any one of both ends of the upper frame upper surface 231, the present invention is not limited thereto, the elastic deformation moving member 270 is It may be applied to both end portions of the upper frame upper surface 231.

When the elastically deformable moving member 270 is moved closer to the other end of the distal end of the isolation flame retardant member 240 by the external force by the operator or the like than the distal end to which the elastically deformable moving member 270 is connected, An end portion of both ends of the isolation flame retardant member 240 to which the elastically deformable movement member 270 is connected may also be formed together with the elastic deformation movement member 270. By moving 270 relatively closer toward the distal end than the distal end to which it is connected, the isolation flame retardant member 240 can be relatively more elastically deformed than before the elastically deformable moving member 270 is moved, thereby The elastic deformation moving member 270 is moved on the cable tray 20 according to the addition or removal of the cable 10. The space between the cable 10 on the cable tray 20 and the upper frame member is always blocked by the insulating flame retardant member 240 while the insulating flame retardant member 240 is in contact with the cable 10. It can be easily adjusted to maintain.

While the invention has been shown and described with respect to specific embodiments thereof, those skilled in the art can variously modify the invention without departing from the spirit and scope of the invention as set forth in the claims below. And that it can be changed. Nevertheless, it will be clearly understood that all such modifications and variations are included within the scope of the present invention.

As such, it is said that the industrial applicability is high.
