Abstract
Abstract A hanger for supporting a spanner beam used in the construction of bridge decks and the like. A bracket includes a flat tongue which rests on a girder and opposed side plates which receive one end of the spanner beam therebetween. A camming pin is inserted through opposed openings in the side plates and rotated to become tightly lodged in a supportive position beneath the spanner beam. A Z-shaped accessory plate may be used to support the bracket in an alternative position a short distance below the top of the girder. A leveling mechanism which rests on top of the girder receives the bracket tongue and is adjustable in order to vary the elevation of the spanner beam.

Total Claims: 5
Claim 1
Independent Claim
246 words
A hanger assembly for supporting a beam member from a support surface, said assembly comprising: a bracket having a pair of parallel side plates spaced apart sufficiently to receive therebetween the beam member at the end thereof and a top web member interconnecting said side plates to overlie the beam member received between said side plates, said bracket further including openings formed through said side plates in alignment with one another, said openings substantially positioned beneath the beam member when said member is received between said side plates and is engaged with said top web; an extension member comprising a base plate positionable to underlie said top web and adapted to be disposed between said top web and said beam member when said bracket is installed thereon, an intermediate web integrally joined to one end of said base plate and extending perpendicularly upwardly therefrom, and a tongue plate integrally joined to the top of said web and extending perpendicularly laterally therefrom to overlie said support surface; an eccentric beam support member having a length greater than the distance between said side plates and sized to be received through said openings in said side plates, and beam support member having a camming surface and being rotatable within said openings whereby when said beam member is received between said side plates said beam support member may be rotated to tightly and grippingly lock said beam member between said top web and the camming surface of said support member.
Claim 2
Dependent Claim
246 words
A hanger assembly for supporting a beam member from a support surface, said assembly comprising: a bracket having a pair of parallel side plates spaced apart sufficiently to receive therebetween the beam member at the end thereof and a top web member interconnecting said side plates to overlie the beam member received between said side plates, said bracket further including openings formed through said side plates in alignment with one another, said openings substantially positioned beneath the beam member when said member is received between said side plates and is engaged with said top web; an extension member comprising a base plate positionable to underlie said top web and adapted to be disposed between said top web and said beam member when said bracket is installed thereon, an intermediate web integrally joined to one end of said base plate and extending perpendicularly upwardly therefrom, and a tongue plate integrally joined to the top of said web and extending perpendicularly laterally therefrom to overlie said support surface; an eccentric beam support member having a length greater than the distance between said side plates and sized to be received through said openings in said side plates, and beam support member having a camming surface and being rotatable within said openings whereby when said beam member is received between said side plates said beam support member may be rotated to tightly and grippingly lock said beam member between said top web and the camming surface of said support member.
Claim 3
Dependent Claim
238 words
A hanger assembly for supporting a beam member from a support surface, said assembly comprising: a bracket having a pair of parallel side plates spaced apart sufficiently to receive therebetween the beam member at the end thereof and a top web member interconnecting said side plates to overlie the beam member received between said side plates, said bracket further including openings formed through said side plates in alignment with one another, said openings substantially positioned beneath the beam member when said member is received between said side plates and is engaged with said top web; an extension member associated with said top web and projecting outwardly from said side plates to overlie said support surface; an eccentric beam support member having a length greater than the distance between said side plates and sized to be received through said openings in said side plates, said beam support member having a camming surface and being rotatable within said openings whereby when said beam member is received between said side plates said beam support member may be rotated to tightly and grippingly lock said beam member between said top web and the camming surface of said support member; and a leveling appliance to overlyingly bear on said support surface, said appliance including a tongue receiving member removably but supportingly connected to said extension member, and adjustment means for selectively varying the elevation of said tongue receiving member above said support surface.
Claim 4
Dependent Claim
238 words
A hanger assembly for supporting a beam member from a support surface, said assembly comprising: a bracket having a pair of parallel side plates spaced apart sufficiently to receive therebetween the beam member at the end thereof and a top web member interconnecting said side plates to overlie the beam member received between said side plates, said bracket further including openings formed through said side plates in alignment with one another, said openings substantially positioned beneath the beam member when said member is received between said side plates and is engaged with said top web; an extension member associated with said top web and projecting outwardly from said side plates to overlie said support surface; an eccentric beam support member having a length greater than the distance between said side plates and sized to be received through said openings in said side plates, said beam support member having a camming surface and being rotatable within said openings whereby when said beam member is received between said side plates said beam support member may be rotated to tightly and grippingly lock said beam member between said top web and the camming surface of said support member; and a leveling appliance to overlyingly bear on said support surface, said appliance including a tongue receiving member removably but supportingly connected to said extension member, and adjustment means for selectively varying the elevation of said tongue receiving member above said support surface.
Claim 5
Dependent Claim
53 words
The hanger assembly as in claim 2, said tongue receiving member having an internally threaded bore and said adjustment means including a threaded shank disposed within said threaded bore with the lower end of said shank engaging said support surface whereby rotation of said shank imparts vertical displacement to said tongue receiving member.
