Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0027] Such as figure 1 As shown, the vertical anti-slip friction plate 1 provided by the present invention for improving the anti-skid safety of the welded cable saddle is a sector-shaped corrugated steel plate, and the sector-shaped corrugated steel plate is uniformly distributed with a plurality of concentric Circular wave train, the trend of the wave train is parallel to the upper edge and the lower edge of the fan-shaped corrugated steel plate, and a plurality of "mouth" shapes or "mouths" are opened on the lower edge of the fan-shaped corrugated steel plate "shaped groove 6.

[0028] The lower edge of the fan-shaped corrugated steel plate is closely attached to the arc top surface of the saddle groove 5, and the g...

Abstract

The invention discloses a vertical skid-resistant friction plate used for improving the skid-resistant safety of a welding-type cable saddle. The vertical skid-resistant friction plate is a fanning-shaped corrugated steel plate, a plurality of concentric circle wave trains are evenly distributed from top to bottom on the fanning-shaped corrugated steel plate, the direction of the wave trains is parallel to the upper edge and the lower edge of the fanning-shaped corrugated steel plate, and the lower edge of the fanning-shaped corrugated steel plate is provided with a plurality of approximately n-shaped grooves. The vertical skid-resistant friction plate selects soft steel with the thickness of 12mm-20mm and the surface of the soft steel needs to be sprayed zinc. The vertical skid-resistant friction plate can conveniently separate the cables of a main cable and closely attach to the cables, the lower edge of the fanning-shaped corrugated steel plate is closely attached to the top surface of the arc of a saddle groove, the groove formed in the lower edge is closely buckled with tooth-shaped projections arranged on the top surface of the arc of the saddle groove, and the vertical skid-resistant friction plate can bear a larger vertical shear force. Therefore the vertical skid-resistant friction plate can ensure that the cables of the main cable can generate an even and effective lateral pressing force on the skid-resistant friction plate, the skid-resistant problem of the saddle of the cable tower and the main cable of a three-tower suspension bridge is solved, and the implementation plan is simple, reasonable, safe and economical.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a vertical anti-slip friction plate for improving the anti-slip safety of a welded cable saddle. Background technique [0002] The suspension bridge is a flexible cable bridge structure whose main load-bearing component is tensioned by the main cable. The self-weight of the main girder, the dead load of the second phase, and the live load of the vehicle are all transmitted to the main cable through the sling, and finally the main cable transmits all the loads from the main tower and anchorage to the foundation. As the span increases, the double-tower suspension bridge needs to build huge anchorages, which reduces the economy, especially for bridges with thick covering layers and deep bedrock burial. Compared with the single-span suspension bridge, the three-tower suspension bridge can significantly reduce the tension of the main cable and the scale of the anchorage. E...
