Abstract: A hollow column having a wall surrounding an inner space is erected. Pre-stressing cables comprising tendons and two cable terminations are pre-assembled. Each tendon is contained in a respective jacket with a protective substance. Each cable termination comprises a block for anchoring each tendon of a pre-stressing cable, a chamber filled with a protective substance on a rear side of the block and a sealing system closing the chamber opposite the block. Each tendon of the pre-stressing cable extends through the sealing system and has its jacket interrupted in the chamber. The pre-assembled pre-stressing cables are installed in the inner space of the hollow column, with the two terminations of each cable bearing against abutment portions provided at the upper and lower parts of the column. The pre-stressing cables can then be tensioned.
