Anchoring Structural elements
FREQUENT APPLICATIONS: WIND TURBINES/ TOWERS/ANTENNAS
To Create a Stable and long-lasting joint between two Structural elements,
Such as securing steel and concrete opponents, they can simply be tightened
Together with prestressing. The Freyssibar ensured a long-term compression
FREQUENT APPLICATION: BRIDGE DECKS/ BEAMS / SLABS
When fitting additional prestessing tendons to existing structures,
Attachments(sheaves) and deviation points need to be created. The anchoring systems for the neds of the tendons are fitted to the heaves, while the main runs are guided through the existing structure that needs structure that needs strengthening by generating a traverse nailing force that creates the necessary friction between each sheaf and the structure.
Assembling precast elements
FREQUENT APPLICATION: VIADUCTS BUILT WITH LAUNCHING GANTRIES/BRIDGE PIERS/FLOATING CAISSONS/3D-PRINTED BUILDINGS
Whether for temporary or permanent applications, the Freyssiber system offers a simple and effective solution for assembling precast concrete elements with prestressing bars.
Connection with a foundation
FREQUENT APPLICATION: BRIDGE PIERS / COLUMNS
Micropiles and prestressing bars can be combined to create a simple and effective foundation for an existing or prefabricated structure.
The prestessing bars create a friction joint between the structure and the sole plate, which is built on micropiles, without any need for a complex and dense rebar arrangement.
Fixing launching noses
FREQUENT APPLICATION: INCREMENTALLY LAUNCHED BRIDGES/ DE-LAUNCHING
Fixing a nose to deck requires the use of high prestressing forces in a confined space. Designers are often faced with the problem of how to arrange the bars in the available space. The wide range of possibilities offered by the Freyssibar systems makes this process much easier since they improve the forces applied to each assembly while reducing the number of bars
FREQUENT APPLICATIONS: BRIDGES/DAMS/BUILDINGS/ CIVIL ENGINEERING STRUCTURES
The Freyssibar and Freysibar+ systems are widely used to create prestressed structures, especially for repairs and strengthening.
FREQUENT APPLICATIONS: JACKING STRUCTURES/WIDENING PIER CAPS AND DECKS/ BALCONIES
The principle for transferring the load from a bracket to a structure through friction can be achieved with a Freyssibar or a Freyssibar + system. During this process, controlling the applied forces is essential for the joint’s performance and safety of the structure.
The anchors ensure the stability of the soil and allow for large and deep excavations. They are often temporary, as the long-term stability of the ground will be ensured by the structure built in the excavation (car parks, basements, etc.).
The anchor is the essential element that transmit forces from a retaining wall to the ground and ensures the overall stability.
Vertical anchors are generally pre-stressed and improve the stability of dams, while reducing water ingress along the contact line with the rock.
Ground anchors are generally used to improve the stability of an existing quay wall.
Anchors ensure the stability of galleries by balancing the forces of the ground. This technique applies to mines and tunnels.
Vertical anchors provide an effective link between the foundation and the ground, while limiting the effects of fatigue when pre-stressed. The anchors can be used for towers, radio masts, wind turbines, etc.
Hydraulic uplift loads
Anchors are used to hold structures in place that are subject to high water uplift pressure and therefore allow structures to be built in underwater areas by compensating for Archimedes’ principle.
Anchoring a cable anchor block to the ground by means of pre-stressed ground anchors makes it possible to limit or cancel the movements, and therefore the fatigue effect.
