<p>A joist hanger (1, 50, 60) for mounting a metal joist (4) to a load bearing wall (3) comprises a top flange (6) terminating in a downwardly extending lip (7) which engages behind an upper course of the wall (3). A backplate (8) depends from the top flange (6) and a side flange (10) projects outwardly from the backplate (8). The side flange (10) has spaced-apart longitudinally extending slots (15) to facilitate longitudinal adjustment of the joist (4). The hanger (1) may be pre-assembled to the joist (4) allowing the joist (3) to be easily placed in position while providing large tolerances in the straightness and alignment of the wall (4).</p> |
