ABSTRACT:
An anchor-clamp is disclosed for clamping to a prestressing member (50) intermediate its length and over a support (68). The clamp (FIG. 1), after initial assembly, is packed in polystyrene blocks (62, 64) for shipment. At the site of use, the anchor-clamp, still in its foam package, is assembled to the prestressing member (50) and then the concrete is poured and allowed to set. After hardening of the concrete, the prestressed member (50) is stressed in the conventional way, the polystyrene package is removed from about the anchor-clamp and the clamp is operated to clamp the stressed prestressing member (50). Thereafter, the entire clamp is imbedded in concrete. When only one intermediate anchor-clamp is used, it may be clamped to the prestressing member (50) prior to the stressing of the same. The polystyrene foam package not only protects the clamp during shipment and assembly to the prestressing member but also protects the same from concrete or water when the concrete is poured and before removal of the polystyrene package. The clamp comprises a compression member (56) threaded to two tubular portions (52) of two substantially identical clamps (20, 30) arranged in facing relationship. The threading of the member (56) to the tubular portions (52) is left-handed for one of the members (52) and right-handed for the other member (52) so that upon rotation of the member (56), it will move the tubular portions (52) outwardly away from each other whereby wedge activators (44) bearing against wedges (32) drive the wedges (32) outwardly within frustoconical bore (28) in hubs (26). This outward movement of the wedges (32) causes them to move together and clamp to the outer surface of the prestressing member (50).
