Adjustable hanger

An adjustable hanger assembly for supporting concrete forms from the top flange of an I-beam of a range of different widths, comprising:

• (a) a first bracket having thereon a flat surface for engaging the top face of the flange and having also a portion extending downwardly below said surface for engaging one edge of the flange,
• (b) said bracket having a first bore extending through said downwardly extending portion thereof at right angles to said flat surface for receiving a vertically extending form-supporting bolt therethrough,
• (c) said bracket having also an internally threaded bore extending parallel with said flat surface,
• (d) a second bracket including a flat surface for engaging the top of the I-beam flange and having an opening extending therethrough at an angle to said flat surface and in a plane perpendicular to said flat surface for receiving a downwardly-extending form-supporting bolt therethrough
• (e) all of said second bracket being located above the plane defined by said flat surface thereon whereby no portion of said second bracket can engage an edge of the I-beam flange,
• (f) said second bracket also having an internally threaded bore extending entirely therethrough parallel with the above said flat surface,
• (g) a threaded rod having one end received in threaded relation in said threaded bore in said first bracket and having the other end thereof received in threaded relation in said threaded bore in said second bracket,
• (h) said opening being in the form of a slot providing for angular adjustment of said form-supporting bolt in a vertical plane parallel with said threaded rod,
• (i) said second bracket also including a bore extending therethrough at right angles to said flat surface thereon for receiving a vertically extending form-supporting bolt therethrough in addition to said angularly extending bolt,
• (j) said rod constituting the sole connection between said brackets whereby the relative spacing of said brackets on said rod is adjustable in accordance with the width of the I-beam flange by relative movement of one of said brackets and said rod, and said rod absorbs both the tension and the compression loads applied to said assembly in use, and
• (k) said slot and the second named said bore in said second bracket being laterally offset on opposite sides of said threaded bore in said second bracket whereby said threaded bolt can be threaded entirely through and beyond said second bracket without contact with a bolt extending through said opening through said second bracket.
