<p>In round steel bar reinforcing units with a concrete covering, providing protection from rust, the spacers for holding them in place are connected by an elastic tension rod. Their setting at equal intervals on teh formwork, where slipping during concreting has to be avoided, is simplified. The spacers which may be made of plastic, are in the form of dobuel discs (1), pref. interconnected by an elastic tension rod (2). Continuous spacing adjustment is feasible. Bars can be laid into the spacers with no further measuring involved and firmly held in place.</p> |
