Cobute combined the structural elements of the beam and the rib in its precast edge rib, a permanent concrete edge shutter. This element consists of an L shaped rib, with zigzag steel and a concrete edge. 

The edge rib by Cobute can be used for the following applications:

  • edge to stairwell
  • edge to cantilever balcony
  • edge to roof slab

The edge rib replaces timber shutters that would increase not only the amount of waste on site but also installation speed while improving the finishing.

TECHNICAL SPECIFICATIONS

    The Engineer design specifies both the steel reinforcement of the edge rib, as well as the height of the side panel, which ranges from 150 to 300 mm. When used combination with the slab system, the rib can include a lip. Once poured, the permanent shutter forms the outer side of a concrete edge, without requiring any carpentry work.

     The system can include a lip (right image) to ease the installation of a panel.

     Edge beams were used as shutters in combination with the precast decking system, to avoid the use of timber shutters and therefore speeding up the installation time.

    When used for roof slabs, the Cobute edge rib creates a monolithic connection with the slab, which avoids shrinkage cracks, usually occurring between masonry and concrete when bricks are used.
