Cable stayed Bridge Main Tower is the anchored end of drag-line, and to ensure the rigidity at tensioning position, steel anchor beam is arranged in king-tower.Relatively
In using steel strand wires or increasing reinforcing bar come for increasing the rigidity of structure, setting steel anchor beam has that construction method is simple, shortens construction week
The features such as phase.According to the segmented construction requirement of king-post, king-post inner space, steel anchor beam structure and process characteristic, king-tower anchoring section
Each segment concrete wants one-time-concreting to complete, and requires king-post concrete structure with one-pass molding after formwork support arrangement, meet reinforcing bar binding,
Installation after steel plate installation, formwork support arrangement, the interim in place and concrete placings of steel anchor beam.
In steel anchor beam installation, to be the position installed according to steel anchor beam in king-post determine king-post merogenesis carrying out, such as
Fruit each steel anchor beam position is respectively provided with king-post merogenesis, causes king-post merogenesis more, to increase king-post main reinforcement connector, prestress steel
The number of turnover of twisted-wire contact and the inside and outside template of king-post has certain influence to the inherent quality of tower column structure and presentation quality.
If one king-post merogenesis of each two steel anchor beam correspondence can not since construction space is excessively narrow between each two joist simultaneously
The steel anchor beam of lower part is installed after the completion of concreting.
