A structure of a broken stone sorting net is provided to produce and install the sorting net easily by excluding a reinforcing wall and to reduce pollutants by minimizing the use amount of resin materials by attaching a resin connecting member only around a perforated plate. In a structure having plural broken stone sorting nets(100) installed with closely coming into contact with the upper part of plural mounting brackets horizontally separated at regular intervals, the broken stone sorting net comprises a metal perforated plate(10) and a resin frame(20). The metal perforated plate has bent portions bent downward at the left and right sides in a longitudinal direction and through-holes formed at the bent portions at regular intervals. The resin frame is composed of a rim portion(20a) fixed to the bent portions of the perforated plate with covering the bent portions and a connecting portion(20b) attached at a part where the rim portions are not formed at the perforated plate, in order to connect the left and right rim portions. A support rod is inserted into the connecting portion to hold the shape of the rim portions and the connecting portion. |
