Patent ID: 8555600

Claim:
A method for erecting a pre-stressed sectionalized and segmented concrete tower, which includes a plurality of concrete tower sections, the method comprising the steps of: building a tower foundation; assembling a first concrete tower section of the plurality of concrete tower sections, the step of assembling the first concrete tower section comprising the steps of: fabricating a plurality of concrete segments having internal vertical and horizontal ducts for introducing pre-stressing tendons; fabricating an assembling support and a lifting harnesses for providing a support to the plurality of concrete segments when assembled in the first concrete tower section, wherein the assembling support includes a plurality of scaffolds; rigidly securing said plurality of scaffolds for workers at different heights along a longitudinal axis of the first concrete tower section to allow the workers to safely pre-stress and condition the first concrete tower section when assembling the plurality of concrete segments; installing with a crane, the plurality of concrete segments on the assembling support to form the first concrete tower section; engaging and securing the lifting harness to the first concrete tower section; lifting the first concrete tower section with the lifting harness; mounting the first concrete tower section on the tower foundation; disengaging the lifting harness from the first concrete tower section; assembling a remainder of the plurality of concrete tower sections through the use of assembling supports and mounting the remainder of the concrete tower sections one by one through the use of lifting harnesses according to the same steps of assembling the first concrete tower section; and joining the plurality of concrete tower sections through vertical pre-stressed tendons to provide a rigid tower, wherein the assembling supports used for assembling the plurality of concrete tower sections are fabricated independently of each other according to each concrete tower section to be assembled.
