Abstract

The invention relates to a stayed-cable anchor plate type anchoring structure of a stayed-cable bridge cable tower, which comprises a steel anchor plate embedded inside a concrete tower post, transverse separation plates are symmetrically and transversely arranged at two side surfaces of the steel anchor plate, vertical separation plates are vertically and symmetrically arranged in the middle position of both side surfaces, a bottom plate is arranged at the bottom of the steel anchor plate, reinforcing ribs are vertically and symmetrically arranged on two side surfaces of the steel anchor plate and the upper surface of the bottom plate, a plurality of PBL shear connectors vertical to the steel anchor plate are symmetrically arranged on the steel anchor plate at both sides of the vertical separation plates, both ends of the steel anchor plate are respectively and fixedly connected with an anchor ear plate extending out of the outer side of the tower post, pin holes are arranged on the anchor ear plate, a side plate parallel to the vertical separation plates is respectively arranged at the connecting parts of both ends of the steel anchor plate and the anchor ear plate, and transverse reinforcing plates with one end corresponding to the positions of the transverse separation plates are fixedly connected on the anchor ear plate. The invention has the advantages of simple structure, definite force transmission, small size, convenient construction, low manufacture cost, safe and reliable structure and simple and artistic appearance, and is suitable for being used by the stayed-cable bridge cable tower with small tower post cross section.

Description

Technical field: [0001] The invention relates to a cable-stayed cable anchoring device, in particular to a cable-stayed cable anchor plate type anchoring for a cable-stayed bridge whose cable-stayed bridge adopts parallel cable planes and has a small cross-section of a tower column. Background technique: [0002] At present, the pylons of long-span cable-stayed bridges generally adopt hollow variable-section pylons, and the cable-stayed pylons with relatively mature technology are anchored with anchoring systems such as circumferential prestress, steel anchor boxes, and steel anchor beams. The annular prestressed anchorage structure is a planar annular prestressed beam arranged in the tower wall, and the external force generated by the prestressed beam is used to balance the internal force generated by the stay cable in the tower wall. The anchorage structure of steel anchor box and steel anchor beam is mainly to resist the horizontal component force generated by the cable b...
