However, the conventional supporting metal fittings have the following disadvantages. The conventional mounting bracket is a type in which the mounting bracket 34 is mounted with two plate pieces 34a and 34b sandwiching an angle as a column, and therefore it is difficult to cope with a difference in the plate thickness of the angle. In the conventional metal support, the receiving plate 32 and the arm 33 must be manufactured separately, and the mounting plate 35 must be bent on the lower surface of the receiving plate 32, or the mounting bracket 34 should be welded to the arm 33. Since it does not happen, it takes time to manufacture. Since the conventional support fitting is divided into the receiving plate 32 and the arm 33, the number of assembling steps is large and cumbersome. Since the conventional support metal fittings are made of sheet metal (welded structure of steel plates), they are heavy and difficult to work. In the conventional steel plate-made support fittings, the cut corners may be edges, which may be dangerous in operation. The conventional steel plate support bracket has a plating thickness of 0.01 mm.
Since it is about 500 g / m ² , there is a problem in corrosion resistance in a bad environment.

In view of the above, the present invention provides a cable laying support metal fitting that solves the conventional drawbacks. First, it can be mounted as it is even for angles (struts) having different plate thicknesses. To provide a support metal fitting that is possible, secondly to integrally assemble the entire body to eliminate the need for assembling steps, and thirdly to eliminate manufacturing steps such as integrally molding and welding the entire body to facilitate manufacturing, 4th is to reduce overall weight by stealing meat, 5th is to ensure safety by forming corners with rounded corners instead of edges, and 6th to improve corrosion resistance. It is intended.
