ABSTRACT:
In steel reinforced concrete structures, a hanging system uses an embeddment anchor with a head or washer positioned behind the second layer of reinforcing from the load being supported. An adjustable length tubular opening or shank extends from the head or washer to the form which forms the surface from which the load is to be supported. In the tubular embodiment, two sealed tube sections telescope with respect to each other for adjustment to the required distance and are held to the head or washer by a removable plastic threaded fastener. After the concrete is poured, the fastener is removed and a threaded stud such as a rod is threaded into the head or washer through the tube. The tube is then sealed. In another embodiment, an internally threaded sleeve is adjusted on a threaded shank to obtain the variable distance from the washer or head to the form.
