Abstract
A screed assembly apparatus for loose or plastic materials such as placed and/or poured, uncured concrete previously placed on the ground or another support surface, includes a screed frame, and mounted thereon, a striker for engaging and spreading the materials and a rotatable auger for moving the material longitudinally along the screed frame. The auger provides a pair of intertwined spiral flight coils. The striker is spaced to one side of the auger and in parallel thereto. An auger mounting means and a motive power means are engaged for rotating the auger to remove excess portions of the concrete from the pour.

3. A screeding method for loose or plastic materials such as placed and/or poured, uncured concrete previously placed on the ground or another support surface, the method comprising the steps of:
- mounting a striker and a rotatable cylinder in parallel on a screed frame;
intertwining dual spiral flight coils on an outside surface of the cylinder from between ends of the cylinder;
positioning the striker spaced to one side of the auger and in parallel thereto;
positioning the auger partially immersed in the uncured concrete; and
rotating the auger for removal of an excess portion of the concrete while drawing the auger and the striker in a lateral direction. - View Dependent Claims (4)
