Metal fiber with chamfered longitudinal corners

摘要

The metal fiber has fiber outer surfaces (1) oriented substantially at right angles to each other and can also be provided with bent ends in the shape of a clip. The metal fiber is used to stabilize, strengthen, or fasten materials such as concrete, wood and the like. The fiber edges (2) formed by the fiber outer surfaces (1) of the metal fiber and extending in the longitudinal direction of the fiber are designed as edge surfaces (4) oriented at an angle to the fiber outer surfaces (1) in the manner of a chamfer. Said edge surfaces (4) have projections, which form anchoring heads (3) that are anchored in the materials to be stabilized, strengthened, or fastened.

1. In a metal fiber having outer faces oriented substantially at right angles to one another, and also having bent ends in the shape of a fastener, for stabilizing, strengthening, or fastening materials and wherein corners formed by outer faces of the metal fiber and extending longitudinally of the fiber are chamfered to form edge faces oriented at an angle to the outer faces, the improvement wherein:
the edge faces have projections that form anchor heads for the materials to be stabilized, strengthened, or fastened, the anchor heads form beveled anchor faces that enlarge the cross-section of the fiber in the area of the edge faces, and a cross-section of the fiber has a substantially square shape in centers of the anchor heads.
