Concrete placing apparatus

Abstract

A concrete placing apparatus comprises a power-operated carriage and mounted thereon a feed hopper, a first and a second endless belts adapted for moulding lateral sides of a concrete layer being formed, and mounted parallel to one another on rolls having a vertical axis of rotation, and a concrete compacting mechanism. The latter is constructed in the form of a third and a second endless belts disposed in one horizontal plane above the first and second endless belts. The third endless belt is intended for exertion vibration action upon the concrete mix being placed, and is mounted on two rolls having a horizontal axis of rotation, at least one of said rolls being provided with unbalances mounted therein on its driving shaft coaxial therewith. The fourth belt is intended for damping vibration of a freshly placed concrete and mounted on rolls having a horizontal axis of rotation behind the third endless belt.
