초록

A light-weight, portable and sturdy vibratory concrete screed which may be fabricated in modular fashion from a plurality of interconnected, separable frame units. A framework is provided, having a series of spaced, parallel unitary frame members of triangular configuration, the corners of the base of each frame member being attached to a pair of screed plates and maintaining the screed plates in spaced-apart relationship. Side braces and base braces extend between adjacent frame members for framework rigidity. An eccentric shaft is supported for rotatio...
