Abstract
Abstract An arrangement for fastening a steel dowel in a dowel hole of a structural member, in which the structural member consists particularly of concrete or wood. A synthetic resin layer is located on the wall of the dowel hole, and the steel dowel is coated with a synthetic resin-filler mixture. The coating of the steel dowel, furthermore, is roughened and may have a ribbed surface. The cross-section of the steel dowel may have a circular or square shape, and the dowel may be an elongated rod or structural angle. A hardener or similar catalyst may be applied to the roughened synthetic resin coating of the steel dowel by means of spraying or immersion.
