A state-of-the-art construction system

Current city architecture has to meet many demands. It must be built sustainably and resource-efficiently, while also creating living space for the growing population numbers in the mega cities quickly and at low cost. Living and comfort quality as well as an attractive architecture are some important factors, as are responses to the worsening climate- and weather-related changes and geophysical nature disasters.

MOTUS construction system as a response

The MOTUS construction system offers an answer for all of these challenges. Earthquake-safety is an essential advantage of the new system construction here. Construction technology has developed greatly, in particular in the last ten years. However, building tall residential buildings in seismically active regions, increasing the carrying capacity of the walls and floors, and combining all of this with attractive architecture highlights such as design and color used to be a near-unsolved challenge to date.

The hollow-core slab as a game changer

In particular the floor structure and the precise, stable connection from floor to wall are decisive for stability in the face of strong shocks such as earthquakes or explosions caused by gas leaks. Traditionally pre-stressed hollow-core slabs are an outstanding material with great savings potentials for costs and time as compared to floors of solid concrete, but without any truly earthquake-proof properties. Special, novel MOTUS reinforced-concrete hollow-core slabs form the basis for true innovation. Solid concrete parts for inner walls and insulated sandwich walls provide a seismically resistant modular construction along with the new flooring construction.

Reinforcement mats and connection reinforcements lead to a positively connected earthquake-safe structural assembly of the floor parts on the construction site. The tension force absorption on all sides clearly increases load-bearing capacity. A tension wire protrusion along the longitudinal sides is very easy to implement here. On the sides, additional reinforcements can be provided for positive connection of the individual ceiling elements. The flexible cavity geometry and structure ensures transverse-force resistance as required from case to case.

Flexible prefabricated geometries

At the same time, much larger floor widths of more than 3 m. This clearly reduces construction-site crane strokes and installation times on site as compared to extruded hollow-core slabs. Additionally, earthquake-proof hollow-core slabs in variable shapes and dimensions can be produced for the first time. This opens up entirely new architectural opportunities.

The climate factor

The MOTUS hollow-core slab is a true game changer in decarbonization of construction as well at up to 40% less concrete and clearly reduced steel consumption as compared to element or solid concrete ceilings. The construction system thus not only lower costs from material use and warrant shorter construction times, it also essentially reduces CO₂ emissions even in the manufacturing process.
