<p>SPACER FOR WIRE REINFORCEMENT IN CONCRETE STRUCTURES SUCH AS PIPE An apparatus, method and assembly are disclosed for spacing a wire reinforcement from a concrete article form such as pipe form. Spacers are employed which include a U-shaped spacer portion extending from a mounting means which includes a positioning means, a torsion means, and arms extending therefrom to hook about a wire in said fabric and be held thereto substantially by the torsion generated within the torsion means. The reinforcement spacers are mounted at spaced points on a pipe reinforcing cage a for example, around the circumference and along the length of the cage so that each spacer portion extends radially outwardly therefrom to hold the cage in properly spaced relationship to the pipe form.</p> |
