Powered roller screed with curb attachment

Abstract

A powered roller screed with a curb attachment is disclosed. The powered roller screed may include a screed roller that is offset (e.g., vertically) from one or more curb rollers used by the curb attachment. In one embodiment, the amount of offset between the screed roller and each such curb roller is adjustable. Generally, each curb roller used by the curb attachment may engage and roller along an upper wall of a curb as screeding operations are conducted on poured concrete alongside the curb.

1 . A powered roller screed, comprising:
 a screed roller;   a drive assembly comprising a power source, said drive assembly being interconnected with said screed roller and operable to rotatably drive said screed roller;   first and second handles interconnected with said screed roller at first and second locations, respectively, that are spaced along a length of said screed roller;   a curb attachment interconnected with said screed roller and comprising first and second curb rollers, wherein said screed roller is vertically offset from said first and second curb rollers.   
     
     
         2 . The powered roller screed of  claim 1 , wherein said screed roller comprises a non-driven end, and wherein said curb attachment is mounted to said non-driven end. 
     
     
         3 . The powered roller screed of  claim 1 , wherein said first and second curb rollers are disposed of a common elevation. 
     
     
         4 . The powered roller screed of  claim 1 , wherein said screed roller is advanced in a first dimension during a screeding operation, and wherein said first and second curb rollers are spaced from each other in said first dimension. 
     
     
         5 . The powered roller screed of  claim 1 , wherein said first and second curb rollers are positionable on an upper wall of a curb. 
     
     
         6 . The powered roller screed of  claim 1 , wherein the said first and second curb rollers each comprise a rotational axis, along with first and second curb roller sections that are spaced along said rotational axis. 
     
     
         7 . The powered roller screed of  claim 1 , wherein a vertical position of said first and second curb rollers is adjustable relative to said screed roller. 
     
     
         8 . The powered roller screed of  claim 1 , wherein said first and second curb rollers are simultaneously adjustable relative to said screed roller in a vertical dimension. 
     
     
         9 . The powered roller screed of  claim 1 , wherein said curb attachment comprises first and second brackets, wherein said first curb roller is rotatably interconnected with said first bracket, and wherein said second curb roller is rotatably interconnected with said second bracket. 
     
     
         10 . The powered roller screed of  claim 9 , wherein said first and second brackets are movably interconnected. 
     
     
         11 . The powered roller screed of  claim 9 , wherein a position of said first bracket is adjustable relative to a position of said second bracket. 
     
     
         12 . The powered roller screed of  claim 9 , wherein said curb attachment comprises a plurality of predetermined adjustment positions between said first and second brackets. 
     
     
         13 . The powered roller screed of  claim 9 , wherein said first and second brackets are pivotally interconnected. 
     
     
         14 . The powered roller screed of  claim 13 , wherein said first bracket comprises a plurality of first adjustment holes, wherein said second bracket comprises at least one second adjustment holes, and wherein each of said plurality of first adjustment holes may be aligned said at least one second adjustment hole. 
     
     
         15 . The powered roller screed of  claim 14 , further comprising a first member extending through one of said first adjustment holes and one of said second adjustment holes to maintain said first and second brackets in a fixed position relative to each other. 
     
     
         16 . The powered roller screed of  claim 9 , wherein said first bracket comprises a curb spacer engageable with a sidewall of a curb. 
     
     
         17 . The powered roller screed of  claim 16 , wherein said curb attachment further comprises an end plug that rotates along with said screed roller, wherein said first bracket is mounted to said end plug such that said end plug is rotatable relative to said first bracket, wherein said end plug extends beyond said first bracket a first distance, and wherein said curb spacer extends beyond said first bracket a second distance that is greater than said first distance. 
     
     
         18 . A concrete pour site comprising:
 a curb comprising an upper curb wall and a curb sidewall; and   the powered roller screed of  claim 1 , wherein said first and second curb rollers are positioned on and roll along said upper curb wall.
