Tightening parallel components in prestressed concrete building structure

摘要

The method involves the tightening of a first individual component or a group of individual components up to a predetermined force and then anchoring them. A second individual component or a group of individual components is then tightened to a force to the same extent as the first group. It is then anchored. The tightening forces of the individual components are directly compared with those of the previously tightened individual components. The first individual component is anchored in relation to an arm (14a) of a weighing beam (14) and the second individual component is tightened in relation to the second arm (14b) of the weighing beam. To tighten the individual components individual tightening presses are used, which are hydraulically connected with each other.
