CONCRETE PLACING AND SCREEDING APPARATUS AND METHOD

摘要

A concrete placing apparatus is provided for placing uncured concrete on a support surface, such as an elevated deck of a building. The apparatus comprises a base unit (16) and a movable support (18), with a conduit assemb ly (14) extending therebetween. A supply end of the conduit assembly is positioned at the base unit and is connected to a supply line (20) for uncur ed concrete or other material, while a dispensing end (14c) of the conduit assembly is supported by the movable support and extends outwardly therefrom to dispense uncured concrete or other material through a discharge outlet. T he movable support is movable arcuately and/or radially relative to the base un it to dispense the concrete in a generally uniform manner over a targeted area. The apparatus may further include a screeding device (72) at the discharge outlet to grade, level, compact and smooth the concrete as it is placed.
