Patent Images
1. A folded plate girder having a bottom side with flanges and a channel therebetween and further comprising a connector system comprising:
- a splice plate fixedly attached to a first end face of folded plate girder, wherein the splice plate is attached at an obtuse angle relative to a longitudinal length of the girder;
a filler plate positioned within the channel and fixedly attached to the flanges and the splice plate;
such that, when the splice plates of two folded plate girders are connected, a bottom side of the girders forms an obtuse arc.

9. A method for attaching folded plate girders to impart camber between the girders, the method comprising:
-
A. providing at least two folded plate girders having a bottom side with flanges and a channel therebetween and further comprising a connector system comprising, a splice plate fixedly attached to a first end face of folded plate girder, the splice plate being attached at an obtuse angle relative to a longitudinal length of the girder; a filler plate positioned within the channel and fixedly attached to the flanges and the splice plate; and B. connecting the splice plate on the first end face of one folded plate girder to the splice plate on the first end face of another folded plate girder, such that an obtuse angle is formed between the bottom sides of the connected folded plate girders. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A kit for joining folded plate girders comprising:
-
a folded plate girder having a bottom side with flanges and a channel therebetween and further comprising a connector system comprising; a splice plate having a plurality of bolt holes and fixedly attached to an end face of folded plate girder, wherein the splice plate is attached at an obtuse angle relative to a longitudinal length of the girder and bolt holes in the splice plate; a filler plate positioned within the channel and fixedly attached to the flanges and the splice plate; and a plurality of bolts for connecting the splice plate of one folded plate girder to the splice plate of another folded plate girder, such that, when the splice plates of two folded plate girders are connected, a bottom side of the girders forms an obtuse arc. - View Dependent Claims (17, 18, 19, 20)
