Cable combined anchoring block of corrugated-steel-web cable-stayed bridge
The invention discloses a cable combined anchoring block of a corrugated-steel-web cable-stayed bridge. A lower tooth block of the cable combined anchoring block is located at the root of a flange plate, an upper tooth block is located at the junction of a box girder top plate and a pre-buried pipe, a stay cable penetrates through the pre-buried pipe, a steel anchor box is arranged at a location, corresponding to a steel crossbeam, of the front end of the anchoring block, one side of the steel anchor box is welded to the steel crossbeam, and shear pins are arranged on the top face, side faces and vertical steel plates of the steel anchor box and are connected with concrete; the steel anchor box is connected with an anchoring backing board through a force transferring plate; the pre-buried pipe, the steel anchor box, the force transferring plate and the anchoring backing board are welded into a whole body so as to form the cable combined anchoring block. According to the cable combined anchoring block, the steel anchor box is arranged in a cable anchoring block of the corrugated-steel-web cable-stayed bridge, the steel anchor box and box girder top plate concrete form a combined structure so as to jointly stress, and meanwhile, a force of the cable is transferred to the steel crossbeam, so that the transfer of the force of the stay cable can be effectively realized, the overall structural performance of a cable anchorage zone is enhanced, and the technical problem that cables are difficultly anchored during the construction of the corrugated-steel-web cable-stayed bridge is solved.
