Description

  The present invention relates to a cable rack, and more particularly to a cable rack that can freely change the distance between a pair of main girders by freely changing the length of a child girder during construction on site.

  The conventional cable rack has a ladder-like structure in which a child girder is attached at a predetermined interval in the longitudinal direction between a pair of main beams, and a cable is placed on the child beam. The size of the cable rack is determined in advance according to the size and quantity of the cables placed on the child girder.

  However, when working on site to install a cable rack, the cable may not fit in a pre-designed size, and the cable may be divided and arranged by a separator. It was necessary to adjust the cable or install a different size cable rack again.

  Therefore, a cable rack in which a child girder is attached at a predetermined interval in the longitudinal direction between a pair of parent girders, in which a side plate is attached to the parent girder so as to be slidable in the width direction of the parent girder ( (See Patent Document 1). There is also a cable rack in which the horizontal rails are telescopically nested (see Patent Document 2).

One end of each of the girders is joined to the opposite parent girder, and the child girders on the other end are respectively superposed in the longitudinal direction and are fastened at least at two or more locations by a bolt material.

  Further, the shape of the coupling hole provided in the sub beam is not limited to a round hole or a square hole, and may be a long hole.

  Further, a fixing member that detachably holds a separator arranged in parallel with the parent beam is attached to a predetermined portion of the plurality of child beams, and the fixing member is made of a metal or plastic wire, The part forms a double ring part, and both ends thereof are provided with bent parts that can engage with each other substantially perpendicular to the sub beam, and the separator is elastically held by the double ring part. In addition, it is possible to move in the longitudinal direction of the child girder by the bent portion engaged with the child girder.

  According to the cable rack of the present invention, the pair of sub beams formed on the substantially inverted U-shaped member is superposed and can be fastened at a predetermined position by a plurality of coupling holes, so that it is accommodated. Even if the size and number of cables are changed, the rack width can be changed on site.

  Furthermore, there is an effect that the width can be linearly adjusted in the width direction of the cable rack by inserting and fastening the bolt material into the coupling hole.

  In addition, the separator attached to the child girder is elastically held by the double ring portion of the fixing member, and can be mounted without the need for a jig or the like. There is an effect that it can move in the longitudinal direction.
