New procedure for the production of prestressed concretehollow-core slabs

Hollow-core slabs weigh up to approx. 40% less than solid floor slabs, thus requiring less concrete in manufacturing. Therefore, they are widely used all over the world. However, the slab widths are strongly restricted due to the manufacturing process. Service ducts as well as concrete block-outs or lifting anchors are not possible. Reinforcement wire mesh and connection reinforcement can only be incorporated to a limited extent and therefore hollow-core slabs are often not suited for construction systems used in earthquake zones. A new manufacturing procedure of Vollert, called Motus, is going to change this now. For the Motus construction system, Vollert was chosen as the runner-up for the 2020 Innovation Prize for Structural Concrete Products.

As early as 2015, Vollert developed in cooperation with the BauMax construction company a special construction system, based on solid concrete elements, for the earthquake prone Chile. An earthquake-resistant construction system with prestressed hollow-core slabs was presented for the first time in 2019. In this system, the hollow-core elements are no longer manufactured in an extrusion process or by a slipformer, but using the principle of a pallet circulation system.

The Motus construction system was already presented in detail in BFT 11/2019.
