发明名称 Powered roller screed with riser wheel
摘要 A rotating cylinder cement screeding system having a drive assembly and handle at one end for powering and controlling the screeding system. The rotating cylinder may be defined by one or more tubular screed roller sections of varying lengths, thereby allowing a user to customize the length of the system to match a specific cement pour. Further, each tubular screed roller section may be supplied with a male and female end for interlocking with each other and for receiving a variety of add-on attachments. At least one riser assembly may be interconnected to a drive assembly end and/or a non-driven end of the rotating cylinder cement screeding system. The riser assembly may elevate the rotating cylinder a distance above a finished slab to prevent the rotating cylinder from contacting the finished slab during a screeding operation.
