An advanced solution for box girders, achieving longer spans and improved slenderness.

Imitates the aesthetics of traditional on-site solutions.

Bridges with parabolic variations, with a difference of around 1 m between the pier and the centre of the opening.

Bridges with linear variations in depth.

Curved bridges with hyperbolic variable depths.

• They act to create a closed cellular section.
• This means breaking the opening down into sections, with half lap joints and wing-shaped elements on piers.
• Centre spans of over 40 m (up to 60 m) with end spans of around 30 m.
• Depths of 1.0 to 1.6 m at the centre of the opening and 1.8 to 3.0 m on the pier.
• Standard widths of 3.30 and 3.96 m.

Overpasses crossing major roads.

Highway viaducts with deck widths of around 12 m, based on a statically indeterminate set-up and large spans.

Large beams for special building structures (pavilions, etc).

Two transverse supports on piers and abutments, with half lap joints in the area where the theoretical moment is zero.

Possible to attach a wing-shaped beam to the side to avoid temporary overturn-prevention end restraints on the pier.

Built using post-tensioned reinforcing.

Cantilever support on 4 temporary or permanent points.

Decks with variable depth slabs using permanent or temporary struts or a variable edge truss.

• Reduced weight in transport due to sectioning of centre openings.
• Facilitates the negative moment of the end restraints on piers by increasing the depth in this section.
• Reduces the shear force by facilitating the arch effect of the pier concrete.
• As a result of the above, maximum spans using prefabricated components.
• Highly characteristic aesthetic affect, coming close to the appearance of an arch bridge.
• Optimised clearance on overpasses.
