Abstract: An improved clamp and method for forming a rebar joint in a vertical reinforced concrete body. A split-sleeve type clamp with contraction means for firmly closing it around the engaged end portions of a dowel rebar and extension rebar has a location tab struck from a central portion of the sleeve, projecting upwardly and inwardly at an acute angle to engage the upper edge of a dowel rebar onto which the sleeve is driven. The method includes forming a sleeve type clamp with a location tab, driving the same onto the end of a dowel rebar directly to its operative clamping position, inserting an extension rebar in the sleeve, and contracting the sleeve to complete the joint.

Abstract: A pipe hanger including a U-shaped yoke and a U-shaped saddle, each having apertures through the ends of the arms with the apertures being alignable by assembly of the saddle arms on the yoke arms in partial overlapping arrangement. A mounting rod inserted through the apertures joins the yoke and saddle together; the mounting rod has a uniform diameter and bent ends of unequal length each disposed at an angle of about 90.degree. to the axis of the rod. The dimensions of the apertures and rod ends are so related that upon insertion of the rod through the apertures, the weight of the saddle maintains the pipe hanger in assembled condition and precludes withdrawal of the mounting rod.
