A clamp (1) is used in conjunction with a plastic strap (5), the clamp locking the strap to the reinforcement iron (6). With this method, it is possible to prepare the reinforcement cage at a location other than at the concrete pipe prodn. unit. - The cage can be transported compactly with the reinforcement rings located adjacent to one another since the plastic strap is pliable. |
