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.

In the reinforcement of a column supported concrete slab having upper and lower surfaces and said slab including portions extending outwardly and transversely from said columns supporting said slab, and in the area of said slab immediately adjacent said columns including a plurality of unconnected reinforcement members arranged in a pre-determined pattern and in embedded within that portion of said slab extending outwardly from said columns and laterally spaced from and adjacent to that portion of said slab directly overlying said columns, each of said reinforcement members comprising: a. support means, b. a plurality of substantially vertically arranged elongate reinforcement elements having at least one projecting end, c. said elements fixedly attached in spaced horizontal relation to said support means, and d. mechanical anchoring means provided for each reinforcement element, at least adjacent said projecting end thereof, for anchoring said reinforcement elements in the concrete slab adjacent at least one surface thereof.
