Precast concrete elements are manufactured in the factory under optimal conditions and weather-resistant according to individual building dimensions. Empty conduits and installation shafts can be installed in the factory for later electrical installation.
Precast elements are manufactured in the factory according to execution plans and statics. When delivered to the construction site, a laying plan and assembly instructions are usually included. Until installation, all ceiling supports must be constructed at the exact height and fully load-bearing. The flatness and cleanliness of the supports is also important here in order to enable the elements to be supported over the entire surface. In the case of precast slabs and hollow stone slabs, linear assembly support with beams and assembly yokes is necessary. The elements are lifted onto the prepared supports with a crane or truck-mounted crane, usually without intermediate storage. Ceilings without a concrete layer can be walked on and loaded immediately, and the grouting of the individual elements can be started immediately. In the case of slabs with a concrete layer, the upper reinforcement must first be installed before concreting the concrete layer.
The precast concrete element as a solid element has advantages above all in terms of very fast installation, low building moisture, no formwork effort, good sound insulation, smooth ceiling soffit, large spans.
