  The conventional clip-shaped piping material support described above has a protruding piece (flange) portion that protrudes outside the angle member or the H-shaped steel between the base piece and the pressing piece formed by folding back one end thereof. It is arranged to be held in place and elastically held, and an electric cable is inserted between the base piece and the holding piece formed by folding the other end to hold it elastically, or to hold it with a binding band outside the holding piece It was.

  For this reason, in the clip-shaped piping material support tool, both the work of arranging and fixing the support tool itself to the frame component and the work of holding the electric cable in the support tool are work that resists the elasticity in the closing direction. In addition, there is a problem that the workability is lacking, and the wire cable itself is exposed to the outer surface of the gantry, so there is much contact with ultraviolet rays and various gases contained in the outside air, resulting in deterioration of the cable cover layer. There was a lack of weather resistance. In addition, in the case of clip-like piping material support, since the support itself is composed of a band plate formed by bending, an edge may stand on the edge portion, and the covered portion of the electric wire cable that hangs down between the supports May come into contact with the edge and be damaged.

  This invention pays attention to such a point, and it aims at providing the cable holding apparatus excellent in workability | operativity and excellent in weather resistance.

  In order to solve the above-mentioned problem, the present invention described in claim 1 is provided with an inclined support material that supports at least the solar panel of the gantry that holds the solar panel at a predetermined inclination angle with respect to the horizontal plane. Is formed of hat steel arranged in a downwardly facing state, both ends of a support rod formed of a steel wire are folded back, and the opening interval between the folded pieces of this support rod is the folded base end of one folded piece And the tip of the other folded piece are formed so as to be substantially equal to the dimension between the outer ends of the flange portion of the hat steel constituting the inclined support member, and the support rod is inserted into the flange portion of the inclined support member. By swinging the other end side with one end of the support rod as a fulcrum, the flange portion of the hat steel is sandwiched between both folded pieces of the support rod, and the electric panel of the solar panel wired in the hollow portion of the hat steel is used. It is characterized by being configured to hold a table.

  The invention according to claim 2 is characterized in that, in addition to the configuration of claim 1, the folded piece portion of the support rod has a sandwich angle of 135 degrees.

  Furthermore, the invention according to claim 3 is characterized in that, in addition to the structure of claim 1 or 2, a locking hole for receiving the end of the folded piece of the support rod is provided in at least one flange portion. It is said.

  The cable holding device for a solar panel support of the present invention is made of hat steel with an opening facing downward, and a support rod is installed across the hat steel flanges. Since it can be accommodated in the hollow part of the hat steel because it is made to wear, it can be suppressed that the electric cable is exposed to the external atmosphere. Since the contact with various gases that are present can be suppressed, the weather resistance can be improved. Moreover, since the support rod is formed of a steel wire rod, the contact portion with the electric wire cable becomes an arc surface, and the covered portion of the electric wire cable can be prevented from being damaged.

  Moreover, as the support structure, since both ends of the support rod formed by folding back both ends are merely locked to the hat steel flange, workability can be improved.
