VARIOKIT Heavy-duty shoring: Either the Heavy-Duty Tower as the Truss Girder are adjustable to the correct height and length.
The VARIOKIT heavy duty towers each support loads of over 200 tonnes. The horizontal assembly of the 10 m high tower sections that the erection of the shoring is both easy and safe.
VARIOKIT Heavy-duty shoring: Motorway bridge over the Rio Sordo, Vila Real, Portugal: Both the superstructure formwork as well as the falsework are based on the VARIOKIT engineering construction kit.
VARIOKIT Heavy-duty shoring: The system is completed by PERI UP for secure access.
VARIOKIT Heavy-duty shoring: Motorway Bridge T4, Paradisia-Tsakona, Greece: For transferring the extremely high loads in the connecting area to the steel arch, the VARIOKIT heavy-duty shoringtowers could be bundled together to form two 42-leg power packages.
The VARIOKIT Heavy-Duty Truss for large spans offers high load-bearing capacity with a low dead weight. A further advantage is the easy assembly procedure.

Overview

With the PERI VST heavy-duty shoring tower and the VRB truss girder the concreting loads of the bridge superstructure can be safely transferred along very large spans. The heavy-duty shoring from the VARIOKIT engineering construction kit allows for efficient solutions, not only for building bridges but also for special applications in industrial construction.

Efficient
The high load-bearing capacity and the structural optimization help to reduce the quantity of required on-site material.

Versatile
Rentable system solutions fulfil the most varying project requirements.

Brilliantly simple
Fast and simple assembly with fitted bolt connections.

Heavy-Duty Shoring Tower VST

Through the incorporation of standardised system components, it is possible to create various shoring systems:

4-leg towers 
Dimensions of 2 m x 2 m in its standard configuration
Or in each statically required dimension up to a max. 6.50 m x 6.50 m

Towers with legs 
In areas that have to bear heavy loads, the load-bearing capacity can be doubled in-situ through the use of plegs.

Shoring tower frames 
Single towers can also be attached to the frames and this enables them to achieve a noticeably higher cross-sectional stiffness in one direction.

Birdcage scaffold 
By connecting individual shoring tower frames, it is also possible to increase the cross-sectional stiffness in the second direction.

Main beam frames 
In the area of abutments and piers, the system can also be implemented as main beam frames up to a height of 10 m, but only with the head support.

The system is supplemented by PERI UP which provides safe access.

Technical Details

  • Leg loads up to 700 kN
  • Deployment up to 40 m in height is included in the assembly instructions
  • Greater heights are possible if incorporated into project-specific planning
  • The head spindle can be operated with overhanging hydraulics when fully loaded
  • With the graduated lengths of the RCS rails, two compensation elements and the head spindle, all heights are continuously realisable.

VRB Heavy-Duty Truss Girder

The system consists of different types of  load and length optimized frames, which enable to continuously create every span with the corresponding combination.

A distinction is made between

Bearing Frame
for transferring the loads into the heavy-duty shoring towers

Coupling Joint Frame
for higher shear forces close to the support as well as for use at intermediate supports and coupling joints

Standard Frame 
for use in the middle span

Standardized and centric connection of horizontal and vertical bracings enable optimal utilization of the load bearing capacity and lead to efficient material input.

The PERI UP modular scaffold is used in order to ensure safe access across the whole span.

Technical Details

  • Optimized for spans up to 40 m
  • Bending moment capacity 3,000 kNm
  • Compensation of longitudinal inclination and cross fall
  • Continuous realization of every span
  • Tolerance compensation of the support position with relocatable bearing
  • Realization of oblique-angled support due to crossing angles
