Formwork girder VARIOKIT VRB

Overview
The VARIOKIT VRB truss girder is designed for bridge shoring and heavy-duty falsework for spans from 25 to 40 m. It delivers very high moment capacity—up to 3,000 kNm—while maintaining a relatively low dead weight. The system is composed of load- and length-optimised frame types that combine to form continuous spans with minimal different components.

Key features

• Intended for transferring high loads across large spans (shoring for spans from 25 to 40 m).
• High moment capacity up to 3,000 kNm with comparatively low dead weight.
• Quick length adjustment: truss lengths easily adapted to variable span widths with a small set of frames.
• Material-efficient design: fewer trusses required thanks to high load capacity, accelerating construction schedules.
• Time-saving assembly: bolted connections reduce on-site assembly time.
• Centric bracing connections for optimal load distribution.
• Integrable with PERI UP modular scaffold for working platforms and access, enhancing site safety and logistics.
• Suitable as load-bearing falsework for edge sections of long-span bridges.

Variations

• Bearing Frame: transfers loads into heavy-duty shoring towers.
• Coupling Joint Frame: handles higher shear forces near supports and is used at intermediate supports and coupling joints.
• Standard Frame: designed for use in the mid-span area.

Additional information
Standardised, centric connections of horizontal and vertical bracings optimise utilisation of the load-bearing capacity and reduce material input, supporting efficient logistics and predictable assembly operations.
