Concrete wedge-shaped cushion block for incremental launching construction of large-span steel structure bridge

The utility model relates to a concrete wedge-shaped cushion block for incremental launching construction of a large-span steel structure bridge. The concrete wedge-shaped cushion block comprises a steel frame, a double-layer steel bar net sheet, a concrete reinforcing layer and a hanging ring. The concrete wedge-shaped cushion block is provided with a wedge-shaped steel frame, the double-layer steel bar net sheet laid in the steel frame is fixedly welded to the steel frame, the smooth concrete reinforcing layer is further poured in the steel frame, and the thickness of the concrete reinforcing layer equals the depth of the steel frame. The hanging ring is fixedly connected to one lateral face of the steel frame. The concrete wedge-shaped cushion block is simple to manufacture, can be manufactured into different thicknesses to meet the construction requirement, is convenient and flexible to use and can be repeatedly utilized, so that engineering cost is greatly reduced.
