ABSTRACT:
A reinforcing member, especially suitable for anchoring to the earth or to a rock, is made up of two or more separate rods which are shaped to fit together to provide a unit with a generally round cross-section and with spiral ribs on the outer surfaces of the unit. Each of the separate rods which make up the member or unit, have two flat surfaces which are radial with respect to the circular unit and which interfit in surface to surface contact with corresponding surfaces of the complementary rods, except that recesses are provided at the interior ends of the radial surfaces which together form a central conduit in the assembled unit. The central conduit may be employed, per se, as an injection conduit for mortar to fix the end of the rod in an anchoring rock for example, or it may act as venting means to assure that air is not retained in hole boring in which the unit is to be secured by mortar or cement. A tubular pipe may be included in the hollow center to facilitate injection or venting. Preferably also, the edges adjacent the outer portion of the flat radial surfaces of the individual rods are rounded off. Tubes for the injection of mortar or venting of air may also be provided in the space formed by the rounded off edges of the rods of the unit.
