Title: Stress-crack-resistant waterproof concrete ceiling construction - with slabs concreted onto beans subjected to prestressing during concreting
IPC: E04C3/29
Filed: 1974-03-06
Abstract: The purpose is to produce concrete ceilings with improved resistance to stress flaws, and thus with improved sealing against water penetration, esp. in park buildings and others exposed to severe weather conditions and drastic temperature fluctuations. A concrete slab, of ceiling or ceiling sections size, is produced by concreting on top of one or more beams which become anchored to it, these being exposed to prestressing forces during the concreting process, and exposed to tension on the side on which the concrete is to be set. The concrete slab is pressure-loaded by means of the beams when the forces are withdrawn after hardening. One or more such slabs are fitted on supports at the ends, to form a pressure-prestressed, sealed ceiling structure. This may be done directly on site.
