ABSTRACT:
The invention relates to the reinforcement of concrete slabs in the vicinity of columns where the slabs are subjected to large bending moments and shearing forces. The invention accordingly comprises a reinforcement for flat concrete slabs comprising a plurality of substantially vertical elongate reinforcing elements fixedly attached in spaced horizontal relation to support means, each element, at least adjacent one end thereof being provided with an enlarged portion which serves to act as an anchor when the reinforcement is embedded within the concrete slab. In their preferred form, the elements consist of thin transverse sections of an I-beam, the support being provided by at least one intermediate horizontal member to which each I-section is welded. In an alternate form, the invention consists in a plurality of spaced apart steel rods mounted substantially vertically from a thin substantially flat supporting base plate, the rods at their upper ends being enlarged, or provided with suitable attachments to facilitate anchorage of the reinforcement within the concrete slab.
