APPLICATIONS
Cofraplus 60 is an open rib trapezoidal and nestable composite
floor deck used for the construction of concrete slabs.
Cofraplus 60 avoids removal of formwork, reduces the dead
weight of the floor and saves one layer of steel reinforcement.
DEFINITIONS / STANDARDS
Steel specification
• Standard NF EN 10326 : “steel bands and sheets for construction
with hot-dip coating”.
• Standard XP P 34-301 : “steel bands and sheets for construction,
galvanised pre-painted or coated with an organic calendereed
construction industry grade film”.
• Standard EN 10169-3 : “Flat products in steel continuously coated
in organic material (pre-painted) - part 3 : product for interior
applications in the construction industry”.
• Steel : S350 GD in accordance with standard NF EN 10326.
Formwork
Cofraplus 60 serves as load-bearing formwork, between joists
for laying without props, or between lines of props and joists.
Its lightness faciliates the handling of large floor decks delivered
up to a length of 15 metres.
Steel reinforcement
The lateral notching binds to the concrete to form a composite
floor slab.
As a steel reinforcement, Cofraplus 60, in 0,75 mm thickness adds
10,29 cm 2 /ml or 13,91 cm 2 /ml of steel with a thickness of 1,00 mm
in the span direction of the floor.
