Description

Cable tray fixture {CABLE TRAY JOINT}

The present invention relates to a cable tray fixing device, and more particularly, to a cable tray fixing device for mounting a cable tray, which is used for wiring various wires such as communication and electricity, across a ceiling of a building, And moreover, it is possible to fix the tray more firmly.

Generally, when wiring various cables such as telecommunication and electricity for installation on a ceiling of a building, a tray connected to the ceiling of the building is installed to prevent the cable from hanging from the ceiling, and the cable is laid on the tray .

The cable tray is fixed to the upper surface of the channel fixedly spaced apart from the ceiling by fixing a fixing bolt to the ceiling. The channel is fixed to the lower end of the supporting bolt rod spaced apart from the ceiling by a predetermined gap To be installed.

Patent Publication No. 0710022 which is a fixing device for fixing a cable tray to such a channel has a coil spring 6 attached to a fastening bolt 9 inserted into a fastening hole 3 of a compression flat steel 2 as shown in Figs. Is formed on the outer periphery of each of the fastening hole (3) and the nut hole (11) on the bottom surface of the compression flat steel (2) and the upper surface of the fastening member (10) V grooves 4 and 14 are formed opposite to each other so that an upper end portion and a lower end of a coil spring 6 fitted to the fastening bolt 9 between the compression bonding plane 2 and the fastening member 10 are inserted into the annular V grooves And a plurality of binding holes 5 and 15 are formed at equal intervals in each of the annular V grooves 4 and 14 formed in the pressing flat steel 2 and the fastening member 10, 6 and the coil springs 6 fitted in the fastening bolts 9 are mounted on the upper and lower annular V-grooves 4, 14, At the upper and lower ends of the spring 6, The binding bending piece (7, 8) were constructed to by inserting a coupling ball (5,15) in a predetermined position in each binding hole (5,15) formed on the contact pyeongcheol 2 and the fastening member (10).

However, since the conventional cable draining apparatus requires separately manufacturing a coil spring, the cost is increased and the coil spring must be inserted into the fastening bolt.

In addition, when the fastening bolt is tightened, the clamping flat can not be kept fixed at the desired position. Since the clamping bolt is rotated in the tightening direction, the bolt is tightened so that the clamping flat is not moved during the fixing operation There is a problem in that the worker is inconvenient and the workability is deteriorated because the worker has to tighten the fastening bolt by holding the crushed flat steel by hand.
