ABSTRACT:
An upstanding plate adapted for supporting one end of an elongated screed member has a flat bottom edge for sliding movement along a generally horizontal surface at the base of a foundation wall. The upstanding plate is connected to one end of the screed members so as to extend below the screed member and support the screed member above the horizontal surface. The screed member may be received within an open bottomed channel secured to the upstanding plate and the plate may be provided with a leading edge which tapers forwardly and downwardly toward the bottom edge. A second elongated screed member may be supported on the upstanding plate and extended through an opening therein for engagement against the foundation wall. A spacer bar maintains the upstanding plate in spaced relation from the foundation wall. The invention further contemplates the combination of the upstanding plate with a pair of screed members and a method of smoothing and finishing a newly poured surface using the upstanding plate and screed member of the invention.
