Abstract
A reinforced concrete joist has profiled angle bars 10, 11 embedded in the outer areas of the joist, with inwardly projecting anchoring elements 16, 17, and has an embedded prestressed tensile reinforcement 18. The profiled bars at the lower edges of the joist have flanges 13 projecting outwards from the joist and forming support surfaces. <IMAGE>
