Cable tray system supporting large loads {System of cable tray supporting much load}

The present invention relates to a cable tray system for supporting a large load, the first coupling portion of the tooth formed on the outside of the fastening hole of the cradle is formed and the second coupling portion formed on the nut, the first coupling when fastening to the floor bar with the nut The present invention relates to a cable tray system for supporting a huge load to make the part and the second coupling part fasten so that the cradle is not separated from the floor bar.

Cable trays are used for laying cables inside buildings. The cable tray is generally suspended from the ceiling to arrange a large amount of wires or communication lines in the basement, and the raceway is suspended from the ceiling to arrange the wires connected to the ceiling lights.

Since the cable trays vary in length depending on the shape of the building, the cable trays generally have a "┗┛" shape, and a plurality of cable trays are connected to the ground and extended.

Usually, the cable tray is mounted on a mounting unit consisting of a cradle connecting the floor and the floor formed in pairs on the ceiling.

However, at present, there are various wirings inside the building, and as a result, the weight of the wiring increases, and thus, the cradle cannot support the wiring, which causes frequent accidents from the floor bar.

The present invention has been made to solve the above problems, to provide a cable tray system for supporting a large load that the cradle constituting the cable tray is not separated from the floor bar.

The present invention for achieving the above object is a cable tray including a side rail which is formed of a plurality of floor units formed in pairs on the ceiling and a cradle connecting the bottom of the floor bar, a plurality of ground rails connected In the cable tray system that is mounted to the cradle, the cradle is formed with a fastening hole formed with a screw thread in the inner circumference so that the floor bar is fastened, the first coupling portion is formed in the outer side of the fastening hole, the floor bar is formed on the outer circumference A thread is formed to be coupled to the fastening hole, one end of which protrudes to the lower side of the cradle, is coupled to the floor bar, and a nut having a sawtooth-shaped second coupling part is formed on the upper surface to be fastened to the first coupling part. , The first coupling portion and the second coupling portion is engaged, characterized in that the coupling force of the nut is increased.

And, the first coupling portion and the second coupling portion is one side of the tooth is greater than 90 ° and less than 180 ° inclined to the lower surface of the cradle, the other side is formed to be inclined less than 90 ° greater than 0 ° to the lower surface of the cradle It is characterized by.

And, the cradle is characterized in that the first coupling portion is formed on both the lower surface of the upper surface, the nut is coupled in the upper direction and the lower direction.

And, the cradle is characterized in that the luminous body (not shown) is mounted on both sides.

As described above, it is possible to prevent the accident of leaving the cradle in the floor bar, the safety insensitivity of people moving to the lower side of the cable tray is eliminated,

The cost of replacement is reduced due to the aging of the cradle,

As the selling price of cable trays rises, it can take an advantage in price competitiveness.

Hereinafter, a cable tray system supporting huge loads will be described with reference to the accompanying drawings.

As shown in Figures 1 to 3, the present invention is formed in the ceiling in pairs and a threaded rod formed on the outer circumference, and a fastening hole formed with a screw thread on the inner circumference to connect the bottom of the floor bar (100) 205 is formed and the cradle 200, the first coupling portion 210 is formed on the outer side of the fastening hole 205 and the cradle 200 is not separated from the floor bar 100 A plurality of mounting units made of nuts 300 are installed, which are screwed under the rod 100 and formed with toothed second coupling portions 310 so as to be fastened to the first coupling portions 210, and a plurality of mounting units are connected to the ground. The cable tray 10 including the side rails are configured to be mounted on the holder 200.

Hereinafter, the configuration according to each embodiment will be described in detail.

≪ Embodiment 1 >

The floor bar 100 is a strength and hardness of the steel material end is inserted into the ceiling.

The floor rods 100 are formed in pairs wider than the width of the cable tray 10, and a plurality of floor bars 100 are spaced apart in the longitudinal direction corresponding to the cable trays 10 connected in plurality.

The ridged rod 100 has a thread shape on the outer circumferential surface in a rod shape, and is coated on the outer circumference to prevent rust from being generated.

The cradle 200 is to connect the bottom of the floor bar 100 consisting of a pair, the number of the floor bar 100 is formed.

The cradle 200 is formed with a pair of fastening holes 205 having a screw thread formed on an inner circumferential surface of the floor bar 100 for screwing.

In the present invention, the cradle 200 has a serrated first coupling part 210 formed along the outer side of the fastening hole 205.

The first coupling portion 210 may vary depending on the size and shape of the nut 300 to be described later. First, less than the width from the inner circumference to the outer circumference of the nut 300 is preferably formed, the sawtooth shape may protrude or be recessed in accordance with the shape of the upper surface on the nut (300).

The cradle 200 has a side cross-sectional view of a 'c' shape, and both ends are bent in a circular shape. This is to form a luminous body (not shown) on both sides of the holder 200, to stably seat the cable tray 10.

In detail, the present invention prevents the cradle 200 from being separated from the floor bar 100, and the cradle 200 is obviously parallel when initially installed. As time passes, the cradle 200 is moved downward when one side is untightened, which can be easily observed because the arrangement of the luminous body (not shown) is confirmed in the evening.

The nut 300 is screwed on the bottom of the floor bar 100 so that the holder 200 is not separated from the floor bar 100.

The nut 300 is a sawtooth-shaped second coupling portion 310 is formed on the top surface is screwed on the bottom of the floor bar 100 is finally in contact with the first coupling portion 210, the first coupling The portion 210 and the second coupling portion 310 are strongly coupled while being shifted.

As described above, the second coupling portion 310 is recessed and protruded, and is formed to be opposite to the shape of the first coupling portion 210. The second coupling part 310 corresponds to the size of the first coupling part 210.

Preferably, the first coupling portion 210 and the second coupling portion 310 has a tooth one side is greater than 90 ° and less than 180 ° to the lower surface of the cradle 200, the other side is the cradle ( 200) The lower surface is formed to be inclined larger than 0 ° and less than 90 °.

That is, when the first coupling portion 210 and the second coupling portion 310 is fastened, the toothed one end of the first coupling portion 210 and the second coupling portion 310 is the opposite side corresponding thereto. The first coupling portion 210 and the second coupling portion 310 is to engage with the other bone portion to combine more strongly.

Figure 4 is a perspective view showing a cable tray system for supporting a large load according to the present invention, Figure 5 is an exploded perspective view showing a cable tray system for supporting a heavy load according to the present invention, Figure 6 is a C-C of FIG. 'Is a side view showing.

As shown in Figures 4 to 5, the cradle 200 is the first coupling portion 210 is formed on both the upper and lower surfaces, so that the cradle 200 is more strongly coupled in the floor bar (100). .

Here, the holder 200 is made of a 'c' shape, as described above, it is easy to screw the nut 300 from the upper side.

On the other hand, the nut 300 is formed on the lower side when the second coupling portion 310 formed on the upper side is not required to be manufactured separately.
