Research in the field of lightweighting and removal of inefficient concrete has been ongoing since 1985 at German universities, and in 1997, the Kubiax Technology Group of companies was established with the help of engineers and specialists from Switzerland and other European Union countries. Now, a collection of experts on lightweight flat slabs reinforced with concrete has been developed.

Since 2007, this knowledge has been made available exclusively to Kubiax Iran and some other countries in the region.

The Kubiax concept:

Kubiax technology is one of the most modern methods of reducing the weight of a structure while maintaining its structural performance. It proudly holds technical approval from the German State Institute for Building Technology (DIBT) and the Building and Housing Research Center of the Ministry of Housing and Urban Development. It won the German Resource Efficiency Award in 2010 and the first green technology selection in Switzerland.

The general principles of this system involve creating a flat slab through in-situ concreting with permanent holes in two directions.

The purpose of these holes (spherical and flat sections) is to remove unnecessary concrete. In fact, the function of the Kubiax slab system is that, together with the internal beam network, a strong concrete membrane is formed at the top and bottom of the slab (resulting from the placement of hollow balls along the central cavity of the concrete slab along two orthogonal axes), thereby removing the non-structural dead load and improving the biaxial bearing capacity, and thus enabling it to be used for a higher bearing capacity than envisioned.

Kubiax panels can reduce the weight of a square meter of panel by 30% compared to flat panels of similar thickness. As a result, the bending capacity of this type of slab is significantly increased compared to flat slabs of the same weight. Depending on the design requirements, the Kubiax roof system can be prefabricated, semi-prefabricated, or applied on-site. Furthermore, this system can be easily combined with other systems such as prestressed systems.

In this system, the beam is truly removable, in which case the lateral load is provided by shear walls. Kubiax is often used as a column-slab system in conjunction with shear walls. In this case, savings are achieved in concrete and steel consumption, while creating a smooth surface without beam hangers in the structure.
