Abstract: A studrail for shear reinforcement for reinforced concrete slabs is composed of a spacing rail (5) and a plurality of studs (6) which are arranged in parallel at a certain distance and provided with enlarged dish-like anchor heads (8) at both ends. The spacing rail (5), produced as a shaped sheet metal rail, grips one anchor head (8) of each stud with its two opposing folded flange edges (10).

Abstract: A reinforcing assembly for use in structural concrete members, such as slabs, footings, raft foundations, beams, walls and columns, has at least one reinforcing stud having an elongate stem and an anchor head at least at one end of the stem for anchoring the stud adjacent a face of the concrete member, and an elongate support element for mechanically retaining therein the anchor head of the stud. The support element is in the form of a U-shaped trough having a base and sidewalls which hold the stud and confine the concrete about the retained anchor head. The trough decreases the size of anchor head necessary to avoid concrete crushing behind the anchor head and distributes some anchorage forces away from the anchor head. The trough also spaces and positions a plurality of studs in the concrete member.

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.
