Separated steel and concrete combined cable tower anchorage zone structure
The invention discloses a separated steel and concrete combined cable tower anchorage zone structure which comprises a cable tower column in a stay cable anchorage zone. The stay cable anchorage zone of a cable tower is composed of two steel anchor boxes oppositely arranged in the bridge direction and a longitudinal connecting beam arranged between the two steel anchor boxes and enabling the two steel anchor boxes to be connected to form a whole. A concrete tower column at a stay cable anchorage zone section is separated and is connected with the steel anchor boxes through shear nails to form a steel and concrete combined structure, and then the steel and concrete combined structure is connected through the longitudinal connecting beam to form a whole. The longitudinal connecting beam bears horizontal pull forces transferred by the steel anchor boxes, and four separated concrete tower limbs bear vertical pressures transferred by the steel anchor boxes. The structural pattern between the two steel anchor boxes can be changed according to the bridge tower landscape demand, different-length setting and hollowing treatment can be performed, the problem of irregular-shaped bridge tower structure design is solved, the separated steel and concrete combined cable tower anchorage zone structure has the advantages of being clear in stress, attractive in appearance, low in construction cost, simple and the like, and concrete bridge tower style design space is widened.
