Jumpform

The Fabquip Jumpform jacking system allows the entire assembly to be raised to the next floor level using one operator to elevate the entire system, (without the use of a crane).

Considerable savings may result in some cases, due to the possibility of eliminating the need for a second crane on a project.

The jumpform jacks and hydraulic controller have been designed with 'fail safe' features.  The jack and controller are individually tested before they are shipped to the project.

A centrally placed electro-hydraulic controller unit interconnects the strategically located jacks through hydraulic lines. Each jack climbs vertically on slotted climbing column. The slots ensure positive gripping and distinct incremental climb. Each column can be fitted with a foot to help spread the load onto the fresh concrete.

When the hydraulic system is activated, each jack simultaneously completes a stroke. If for any reason there is differential in the initial elevations of the climbing columns, the first stroke will take up the difference. Thereafter, all jacks will simultaneously travel the full 40mm stoke height.

Guide wheels, fixed to shear keys and forms, provide additional stability during climbing operations. Each shear key has a built-in manual screwjack to facilitate minor adjustments. Full verticality is therefore assured throughout the climbing and forming operations.

Technical services

Full Jumpform Systems consulting services are available through Fabquip central engineering office. Fabquip technicians are available to advise, assist and train the contractor in the assembly and operations of the jumpform system.

Self climbing, modular forming system

Fabquip Jumpform system is a fully modular, self-climbing forming system for high-rise construction. Jumpform offers simplicity for conventional forming practices and materials along with demonstrated ability to increase construction speed, economy and safety when compared with conventional construction methods.

Field-tested and proven on hundreds of projects throughout Australia, Middle East, Asia and North America, the Jumpform System represents a major step forward in formwork.

Completely flexible system application

The Fabquip Jumpform System consists of five major, fully recoverable sub-systems: the formwork, upper gridwork, shears key, access scaffold and jacking systems. Each sub-systems is carefully designed to provide safety and full flexibility in application throughout the forming operations.

Custom assembled to your specifications

All forms in the Fabquip Jumpform System are custom assembled from modular components and hardware. Form faces can be prepared to meet virtually all architectural specifications for surface finish.

Panels are secure by only two levels of ties and interlock at both internal and external corners. Each form is suspended from the gridwork sub-system allowing the movable forms to be individually rolled in or out as required for easy placement of reinforcing steel and other subtrade work.

Automatically pivoting shear key for one-step operation

The shear key Sub-Systems securely supports the entire jumpform assembly and all live loads while the system is the reusable, pre-formed plastic shear key pocket. The shear key pockets are fixed to the forms at predetermined elevations, providing set load transfer points at each pour end.

Upper gridwork provides spacious work deck

The upper gridwork system provides a clean and spacious work deck for material landing and concrete placement. Job shacks, toolboxes and other necessary services remain in place on the work deck throughout the form setting, stripping and climbing cycle.

A high wall around the perimeter of the work deck ensures the safety of workers.

Safe, weather-protected enclosed access

The Jumpform System supports both internal and enclosed external scaffolds. Two levels of internal suspended scaffolds allow direct access to both form ties and supporting shear keys.  A third level may be added for auxiliary work.

The external trailing scaffold lets the external forms be rolled well clear of the concrete line. This allows forms to be cleaned and oiled, blockouts to be placed and reinforcing steel installed.

The external scaffolds are fully enclosed allowing work to proceed in the safety and comfort, protected from inclement weather.

 Advantages of the Fabquip Jumpform System include:-

  •  Complete integrated wall systems accurately assembled only once at ground level and ready to climb to the next level immediately after the completion of the 1st pour cycle.
  • Eliminates cranage for lifting of formwork panels and scaffold requirements.
  • After initial training, the system can be operated by an experienced formworker and semi-skilled labour.
  • Work decks are included in design for maximum efficiency and safety.
  • Adjustment to wall thicknesses and profile changes are considered during initial design to reduce loss of construction time.
  • Assists accurate positioning of slab connections, blockouts, doorways, lintel beams and all penetrations to be placed within the concrete core walls.
  • Form design is easily modified to provide architectural features and textures.
  • Reduces construction period and labour cost due to repetition of floor to floor activities.
