Abstract

A shearhead for reinforcing junctions between for example vertical columns and horizontal floors where at least the floor is formed in reinforced concrete. The shearhead is in the form of a hoop bar (2,20,22) for extending around a column (4,24) with a plurality of shear legs (6,8,18,28) depending therefrom. Each shear leg includes a portion (16) extending above the hoop bar, which portion forms a hook (14) for coupling to reinforcement (10) in the slab of concrete extending laterally from the column.
