ABSTRACT:
An adjustable hanger for supporting a concrete form which includes a first bracket having a downwardly-extending portion for engaging an edge of an I beam flange, a second bracket for engaging an I beam flange, and a threaded rod screwed into and extending between the first and second brackets so that the second bracket can be adjusted in spacing from the first bracket to enable the hanger to accommodate a variety of I beam flange widths. In the preferred embodiment, the second bracket includes an upwardly extending portion having a wedge-shaped slot and an outer arcuate bearing surface. The upwardly extending portion receives a bolt for supporting cantilevered formwork and the bolt is retained within the slot by a nut which rests against the arcuate bearing surface. The retained bolt can be pivoted throughout a range of angular orientations relative to the second bracket as the circumstances of use may require. The first and second brackets each include a through bore for receiving additional formwork supporting bolts that are oriented substantially perpendicularly to the threaded connecting rod.
