Discover the advantages of the rib canceller

The Atex rib canceller is a resistant and precise piece. It fits perfectly between the bidirectional moulds for ribbed slab and maintains its position during concreting.

The end result is the construction of a unidirectional ribbed slab, guaranteeing more agility, practicality and economy during this process. It can be used with the mould families Atex610U, Atex640U, Atex 655U, Atex 685U, Atex 755U, Atex 800U, Atex 830U and Atex 875U.

Possible
Applications

Mushroom Slab

The mushroom slab eliminates the use of beams and has only a small massive area (about 20%) in the region of the columns, being ribbed in the rest. It can reduce up to 40% of the use of concrete in the ribbed area compared to the solid slab without beams.

Precast Ribbed Slab

To facilitate the logistics of your project, the ideal is the combination of beams and precast pillars next to the slab cast in place. This method is perfect for smaller areas as it avoids taking up space on the job site with lifting equipment.

Prestressed Ribbed Slab

Any slab built with Atex modular solutions – with beams, strips, or mushroom – can also be prestressed. Prestressing uses steel cables inside sheaths that, when pulled, lengthen and, after the jack's effort, shorten. This process imposes a compressive stress on the slab that eliminates the initial tensions related to permanent loads.

Ribbed slab with beams

Atex ribbed slab formwork supported by beams is the most used solution. It offers ease of assembly and reduces up to 40% of the consumption of concrete and steel on site.

Ribbed Slab with Horizontal Holes

The Tubex ® system applied to the ribbed slab eliminates concrete that has no structural function, generating an additional savings of 10%. This system makes it possible to install ventilation ducts, hydraulic pipes and electric gutters crossed over the slab, increasing the free area on the right foot or allowing the building's height to be reduced.

Ribbed Slab with Metal Structure

The Atex system for slabs that combines metal beams and pillars is an agile and economical solution. The process needs little workspace, is faster and requires less metal beams even for larger spans.

Ribbed Slab with Strips

The ribbed slab supported by strip beams has a single horizon of formwork and shoring, which increases productivity by facilitating the execution of the work.

Seismic adjustments

To prevent damage linked to seismic risk, the measurements of the pillars must often be adjusted. With the use of Atex circular pillar formwork, this becomes simpler. They can be moved manually, as they are lighter and more modular and the handles allow side installation, avoiding having to place them from above.
