Description

Construction cable tray fixing device

The present invention relates to a cable tray fixing device for construction, and more particularly, to a cable tray fixing device for construction that can easily fix a cable tray and a channel while increasing a bonding force.

In general, a cable tray fixing device refers to a device that fixes a cable tray for wiring various cables, such as for communication and electricity, to a channel connected to the ceiling inside a building.

In addition, the cable tray fixing device is configured to be connected by bolts so that the upper and lower coupling pieces can be interlocked, and the cable tray is crimped and fixed to the channel by tightening the gap between the upper and lower coupling pieces.

Such a cable tray fixing device performs a role of fixing the cable tray to the channel to some extent, but its use method is too inconvenient and difficult to use.

In other words, when tightening the bolts of the cable tray fixing device, the lower bolt coupling piece rotates along with the rotating bolt, so the other hand that does not tighten the bolt must take measures to prevent the bolt coupling piece inserted inside the channel from moving. It was possible. Therefore, if you are not a skilled worker, you cannot install the cable tray well, and the work speed is inevitably lowered.

Thus, so far, there have been many proposals for a cable tray fixing device that is relatively easy to use.

As an example, Korean Patent Registration No.0710022, by inserting a coil spring into a fastening bolt inserted into a fastening hole of a crimped flat iron, and bolting it to a nut hole of a fastening nut piece, each fastening hole and An annular V groove is formed on the outer periphery of the nut hole so that the upper and lower ends of the coil spring that are inserted into the fastening bolt between the crimped flat iron and the fastening nut piece are loaded into each annular V groove, and the crimped flat iron and the fastening nut piece When a plurality of binding holes are formed at equal intervals in each of the annular V grooves formed in the coil spring, and the binding bent pieces are formed at the upper and lower ends of the coil spring, respectively, and the coil spring that is fitted to the fastening bolt is loaded into the upper and lower annular V grooves. It is intended to provide a cable tray fixing device that inserts the binding bent pieces formed on the upper and lower ends of the coil spring into the binding holes at a predetermined position among the respective binding holes formed on the crimped flat iron and the fastening nut piece.

However, the above patent has another inconvenience in that it is necessary to insert the coil spring into the fastening bolt one by one, and there is a disadvantage in that the cost is added because the coil spring must be separately manufactured. In addition, the bundling piece of the coil spring must be inserted into each of the fastening holes of the crimped flat iron and the fastening nut piece so that they remain in an immobile state when tightening the fastening bolt.This also causes another inconvenience, so the ease of use is greatly improved It was not possible
