Description

  The present invention relates to an adjustment bracket for a separator support suitable for supporting a separator in the cable rack in a state where a mesh plate is laid on the bottom of the cable rack, and in particular, the separator without the mesh plate being processed. The present invention relates to an adjusting bracket for a separator support that can be supported.

  Generally, when a cable is wired to a cable rack, the cable is exposed at the bottom of the cable rack. Therefore, in consideration of safety and aesthetics, a synthetic resin or metal net-like plate may be laid at the bottom of the cable rack.

  Various electric wires such as a high-voltage wiring, a low-voltage wiring, a weak current wiring, and an optical fiber cable are wired in this cable rack. In this case, although it depends on the facility location, the place where the high-voltage wiring and other wiring approach or cross each other must be separated by at least 15 cm. However, when separating in a cable rack, it is often impossible to maintain this distance. Therefore, if a robust fire-resistant partition is provided instead of the distance to be separated, wiring can be performed without separating 15 cm or more. . This solid fireproof partition is the separator.

  As metal fittings for fixing the separator to the cable rack, for example, metal fittings described in Patent Document 1 and Patent Document 2 have been proposed.

  The support of Patent Document 1 is a metal fitting that is fixed to the upper surface of a child rack of a cable rack, and is screwed by inserting a connecting bolt from a support disposed on the upper surface of the child beam into a nut mounted inside the child beam. The fixed support is provided with a support piece and a sandwich piece, and the separator body is sandwiched between them.

  The support described in Patent Document 2 is a metal fitting that is also fixed to the upper surface of the sub-girder of the cable rack, and is a screw that is inserted into the nut mounted inside the sub-girder through the connecting bolt from the support disposed on the upper surface of the sub-girder. Stop. In this support, an attachment piece bent at the lower end portion of the partition piece of the separator is provided so that the cable rack is fixed by crimping the attachment piece on the side of the sub-girder.

  The support device described in Patent Document 3 is provided with a lower metal fitting extending from the lower surface of the sub-girder to the upper surface of the sub-girder, and screwing the lower metal fitting into a groove provided at the lower end of the separator placed on the upper surface of the sub-girder. It will stop.

  According to the support of Patent Document 1 and Patent Document 2, since the support is fixed to the upper surface of the child girder, when a net-like plate made of synthetic resin is laid on the bottom of the cable rack, this child girder is attached to the net-like plate. It will be hidden. For this reason, in order to attach the support tool to the child beam, it is necessary to remove a part of the mesh plate covering the child beam, which has a disadvantage that the work process of the cable wiring work becomes complicated.

  In addition, instead of removing a part of the mesh plate, it is possible to combine the mesh plates with different widths so that the mounting position of the support device is not hidden by the mesh plate. It was necessary to order a board or to cut a normal mesh board, which was costly and troublesome.

  According to Patent Document 3, the lower metal fitting is attached to the lower surface of the sub-girder. However, in order to screw on the separator placed on the upper surface of the sub-girder, the mesh plate on the upper surface of the sub-girder also obstructs. Therefore, processing into a mesh plate is required. In addition, in this support tool, the support tool is exposed on the lower surface of the child girder, which impairs the aesthetics, which is contrary to the purpose of the net-like plate laid in consideration of the aesthetics of the cable rack bottom.

  Therefore, the present invention was created to solve the above-described problems, and an object thereof is to provide an adjustment bracket for a separator support that can support the separator without processing the mesh plate laid on the bottom of the cable rack. It is what.
