Abstract

A tubular rung intended to be anchored in soft concrete (5) and consisting of a tubular aluminium element (2) bent in the form of a U, the two ends (6,7) of which are each equipped with a plastic fastening dowel (8,9) provided externally with hook-shaped annular ribs (17,18,19), the fastening dowels (8,9) of which having on their circumference means (30) for stiffening the annular ribs (17,18,19) and means (26,27) for absorbing soft concrete driven back during the penetration of the fastening dowels (8,9) into the soft concrete and for evacuating the air pocket contained in the foreholes made in the hardened concrete.
