Reinforcing strips for pre-cast construction elements

摘要: A novel metallic reinforcing strip as described for use in cementitious construction elements. The one form comprises an elongated unitary having a substantially flat central web portion, with the side edges of merging by way rounded corners small radius into flange portions extending away from web. At least free longitudinal flanges are inclined inwardly and these have longitudinally spaced depressions pressed downwardly therein. These cause associated deformation less than full depth flanges, leaving undeformed adjacent outwardly bowed between depressions. contours provide double curvature providing maximum membrane resistance within minimum bending or flexing stresses. When embedded element, curvatures mechanical interlock both lateral directions, enhancing strength rigidity element.
