Abstract

Abstract An improved joist hanger for supporting steel, wooden or other joists from beams, such as I-beams, wherein a separate bracket is attached at a distance from the beam to each of a pair of conventional joists abutting opposite sides of a conventional girder or beam, and a strap with its ends fastened together links the two brackets over the beam so that both joists are supported vertically by the beam and continually pulled toward it to improve the load distribution of the joists as well as to generally improve the support characteristics of a floor or other structure comprised of such joists and beams.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 137 words
A joist hanger for supporting two joists abutting opposite sides of a girder at approximately the same location on said girder and extending approximately at the right angles to said girder comprising: a first bracket attached to one of said joists at a location at a distance from said girder, a second bracket attached to the other of said joists at a location at a distance from said girder and at least a single flexible strap with one end connected to and in direct contact with the other end to form a continuous loop for connecting said first bracket to said second bracket and over said girder so as to support said two joists in approximately the same plane as said girder and to pull said two joists toward said girder so as to abut said girder.
Claim 2
Dependent Claim 137 words
A joist hanger for supporting two joists abutting opposite sides of a girder at approximately the same location on said girder and extending approximately at the right angles to said girder comprising: a first bracket attached to one of said joists at a location at a distance from said girder, a second bracket attached to the other of said joists at a location at a distance from said girder and at least a single flexible strap with one end connected to and in direct contact with the other end to form a continuous loop for connecting said first bracket to said second bracket and over said girder so as to support said two joists in approximately the same plane as said girder and to pull said two joists toward said girder so as to abut said girder.
Claim 3
Dependent Claim 18 words
A hanger as in claim 1 wherein said single strap passing over said girder is adjustable in length.
Claim 4
Dependent Claim 67 words
A hanger as in claim 2 wherein said joists are wooden and have a saw cut at a distance from said girder slanting away from said girder and wherein said first and second brackets are U-shaped members fitted about said joists with closed slots for alignment with said saw cuts so that said strap passes through the saw cuts and slots of each said bracket and joist.
Claim 5
Dependent Claim 38 words
A hanger as in claim 3 wherein each said bracket includes tab means adjacent to said slot for crushing the wood of said saw cut when said strap is tightened to form a bearing surface for said strap.
Claim 6
Dependent Claim 33 words
A hanger as in claim 1 wherein each of said joists is metal and each includes a closed aperture at a distance from said girder so that said brackets fit in said apertures.
