发明名称 Weldless spacer
摘要 <p>A weldless (10) spacer for manually connecting without a tool two reinforcement cage wires or re-bars of a concrete reinforcing structure in spaced-apart relation is a unitary resilient wire member that has an elongated spanning portion (12) that extends between the reinforcement wires, a hook end portion (14) at one end of the spanning portion (12), and a fastening end portion (16) at the other end of the spanning portion (12). The hook end portion (14) includes a detent part (20) and a V-hook part (24), which are joined by a spacer loop part (20) and capture one of the reinforcement wires. The fastening end portion includes a detent part (16) and a J-hook part (30), which are joined by a spacer loop part (28) and capture the other reinforcement wire. One or both of the spacer loops (20,28) are sized to space the reinforcement wire(s) at a desired distance(s) from the adjacent concrete form wall(s) for sufficient concrete cover.</p>
