Cable-stayed bridges
Product Description
- Prefabrication makes it possible to comprehensively resolve decks for cable-stayed bridges by means of precast segments.
- Strict control over geometry and structural issues during the manufacture of the different parts of the structure in the factory.
Main Characteristics
- Strict control over the geometry of the components.
- Combination of different elements within the same structure.
- Prefabrication makes it possible to build more quickly and simply than bridges built on-site.
- Excellent geometry due to placement of specific moulds for these elements.
Types Of Structures Where It Can Be Used
- Use of large load-bearing length-wise beams, precast in segments.
- Use of precast beams between the main load-bearing components.
- Use of crossties to support the beams length-wise.
Main Applications
- Cable-stayed bridge spans between 100 and 250 m.
- Used in Spain for the Fernando Reig Bridge over the Barxell River in Alcoy and for the V-Century Bridge in Seville (Spain).
Advantages
- Avoids interference on the work-site and the need for complex on-site installations.
- Shorter construction period, as the different components can be made in parallel.
- The materials and pieces attained are fully checked prior to insertion in the deck. Quality assurance.
- High quality, rigid moulds are created, permitting excellent geometric shape of the piece.
Construction Details
- Typical arrangement of two large load-bearing beams at the edges, crossties and precast beams between the ties.
