SELF-BALANCED TYPE CABLE TOWER STRUCTURE

PROBLEM TO BE SOLVED: To provide a cable tower constituting a structural body with tensile members. SOLUTION: A lower portion of a tower shaft supporting the dead-weight of the tower is supported by angle braces raised diagonally upward from a tension ring at the boundary portion, and the tension ring is supported by a plurality of leg frameworks on the ground surface. A plurality of cables are arranged in vertical direction along the outer periphery of dwelling facilities such as compression rings, observation platforms or the like located at the outer peripheral portioned at intervals in up-down direction of the tower shaft, the bottom ends of the cables are connected to the tension ring at the boundary portion and the top ends are connected to the top of the tower shaft in a manner transmitting the stresses respectively, and the axial force of the angle braces supporting the dead-weight of the tower greatly exceeds tension in the cable in vertical direction thereby looseness in the balanced cables is not created. The dead-weight of the tower exceeds the horizontal load thereby prohibiting the occurrence of a balanced pull-out force to the horizontal load.
