Vertical anti-skid friction plate used for improving anti-skid safety of welded type cable saddle

The utility model discloses a vertical anti-skid friction plate used for improving the anti-skid safety of a welded type cable saddle. The vertical anti-skid friction plate is a sector-shaped corrugated steel plate, wherein a plurality of concentric circle wave trains are uniformly distributed on the sector-shaped corrugated steel plate from top to bottom, the trend of the wave trains is parallel to the upper edge and the lower edge of the sector-shaped corrugated steel plate, the lower edge of the is provided with a plurality of square-shaped grooves or grooves shaped like a Chinese character 'tu'. The vertical anti-skid friction plate adopts soft steel with the thickness of 12-20mm, the surface of the vertical anti-skid friction plate is subjected to zinc spraying treatment, the vertical anti-skid friction plate can conveniently separate cable strands of a main cable and be tightly fitted with the cable strands, the lower edge of the vertical anti-skid friction plate is tightly fitted with an arc top face of a saddle groove, and the grooves formed at the lower edge of the vertical anti-skid friction plate are tightly buckled with tooth-shaped bulges arranged on the arc top face of the saddle groove, so that larger longitudinal shear force can be borne, accordingly, the cable strands of the main cable can generate uniform and effective lateral extrusion force on the vertical anti-skid friction plate, the anti-skid problem of the saddle of a cable bent tower and the main cable in a three-tower suspension bridge is solved, and the implementation scheme is simple, reasonable, safe and economic.
