ABSTRACT:
A hand-held screed for use in making a sidewalk includes a rectangular plate. The plate has a bottom edge suitable for subgrading and for levelling concrete, and a top edge opposite the bottom edge. At either end of the plate, a projection extends beyond the top edge. A handle is affixed to one of the major surfaces of the plate and is braced by a pair of struts. The plate has a width, as measured between the top and bottom edges, equal to the intended depth of the sidewalk. The plate further has a length equal to the intended width of the sidewalk. A form is erected and the area within the form is subgraded using the bottom edge of the plate. The plate is oriented with its length dimension running widthwise of the form. When the top edge of the plate is flush with the top edges of the form, the depth of the area within the form equals the intended depth of the sidewalk. Concrete is now poured into the form and the wet concrete is subsequently levelled using the bottom edge of the plate. The plate is again oriented with its length dimension running widthwise of the form. After levelling, the plate is inverted and control joints are laid using the projections.
