FRANK manufactures a varied range of box-out shutters made of steel and cardboard to create apertures and recesses. These products correspond to all relevant national and international guidelines and standards.
FRANK box-outs are manufactured from formed sheet steel. Therefore, for many sizes of box-out additional stiffening is not required. For detailed information please refer to the corresponding stiffening chart. For large box-outs additional inside stiffening with wooden bracing is usually required for increased stability and better resistance to the concrete pressure.
Instead of bracing on site, we can supply the preassembled box-outs complete with bracing.
Cardboard box-out forms are an economic and efficient means of creating slab apertures.
For larger openings we recommend the use of sheet steel box-outs.
The joint profile former is a plastic profile used as formwork for concrete sections. After removal of the joint profile former, the first concrete section is ready for the pouring of the second concrete section.
The FRANK Flexischaler provides an individually shaped formwork and ensures perfectly straight shuttering for precast applications.
The FRANK range of specialist permanent formwork offers solutions to the need for innovative formwork for many in-situ and precast concrete structures.
A range of fibre concrete, fibre cement and cement based wooden chipboard formwork for a variety of permanent formwork applications.
Permanent edging formwork made of fibre-reinforced concrete is used as formwork in semi-precast and precast elements:
This shutter panel is used as a floor-edge formwork and as a covering for formwork joints in insitu concrete constructions.
This formwork element with bevelled edges is used as permanent formwork for the edge beams of bridges.
Shutter panels made of fibre cement are used as permanent infill formwork between steel beams for bridge construction. They are also used as building boards for cladding of structural members and as backing strips for the erection of prefabricated building components. These cement-based panels are extremely durable.
Lintel formwork is manufactured using a high-pressure, cement bonded chipboard which is a category B1 flame resistant material. The use of these lintel forms reduces the cross section of the lintel to be concreted. Using permanent lintel formwork at the construction site facilitates faster more efficient formwork erection and concreting of ring beams and lintels.
These forms are a cost efficient permanent floor edge element without insulation properties. Floor-edge forms are produced with grouted anchor holes on the inside surface in order to ensure a good bond with in-situ concrete. The floor is ready for concreting approximately 2 hours after fixing of the form in position.
Floor edge and ring beam insulating forms for eliminating cold bridging in buildings. The use of these forms replaces time consuming traditional walling operations and the need for temporary formwork.
DIS floor-edge insulating forms act as a permanent formwork for the floor-edge:
Combining a 60 cm thick floor-edge insulating element on the outside with a 30 cm thick element on the inside a ring beam shuttering can be produced. The required stability is achieved using re-usable clamps.
