Description

TECHNICAL FIELD The present invention relates to a separator fixture for fixing a separator installed in a cable rack.

A cable rack is used to install electric wires in a building. Separators are sometimes installed in cable racks for the purpose of separating heavy and weak wires. In some cases, a net-like body is laid on the bottom of the cable rack for the purpose of protecting the installed cables and preventing small animals from entering.

Conventionally, as metal fittings used when laying both a net-like body and a separator in a cable rack, there is known a metal fitting body that is fixed to the cord of the cable rack and a support that supports the separator ( Patent document 1). The fitting body of this fitting is provided with an adjustment hole (long hole), and by adjusting the position of the mesh of the mesh on the adjustment hole, the support can be fixed to the fitting body without processing the mesh. can be done.

Japanese Patent Application Laid-Open No. 2009-189180

Since the supporting member of Patent Document 1 is configured such that the separator is held between two opposing holding pieces, a tapping screw for fixing the supporting member is used in order to adjust the position of the separator in the cable rack. You have to remove it and change the mounting position of the support. In this case, it was necessary to change the mounting positions of all the supports fixed to the beams, which was a great labor for the workers.

The present invention has been made in view of such circumstances, and an object thereof is to provide a separator fixture that allows position adjustment of the separator without removing the support from the metal fixture body.

A separator fixture of the present invention is a fixture for a separator to be arranged in a cable rack, comprising a receiver fixed to a stringer of the cable rack, a net-like body arranged above the receiver, and the net-like body. It is equipped with a pressing tool for pressing both separators placed on the upper side of the body.

Since the separator fixing device of the present invention includes the pressing member that presses the separator from above, the position of the separator can be adjusted only by adjusting the tightening force of the pressing member.
