ABSTRACT:
The apparatus comprises a first horizontal bar adapted to be coupled to a building column and a second horizontal bar is rotatably coupled to and beneath the first bar. A bracket which can be coupled to a screed is coupled to the second bar so that it can rotate with respect to the second bar and it can slide with respect to the second bar. The apparatus is pivotably mounted on opposite columns in an area where a concrete floor is to be leveled and the brackets are coupled to the ends of a screed which the operators wish to move up to the columns and then move around the columns, all the while smoothing and leveling the concrete. The pivotability of the first bar and the rotatability of the second bar and the pivotability and slidability of the bracket with respect to the second bar, permits the operators to move the screed so that first one end thereof can be moved in front of its column and then to the other side of the column and then the second end of the screed can be moved in front of and to the other side of its column.
