CONCRETE FLOOR FINISHING MACHINE

WIPO Patent Application WO/1986/004633

A1

Floor finishing machine for smoothing the surface of a concrete floor while the placed concrete is in a semi-solidified condition, and a floor finishing material can be laid directly on the smoothed floor surface. The floor finishing machines used for this purpose include a floor finishing machine having a single finishing unit adapted to be turned around a carriage. However, in this floor finishing machine, it is difficult to control the movement of the carriage since moment is applied thereto due to the reaction force which the finishing unit receives from the concrete floor surface. According to the present invention, a plurality of finishing units are provided on a carriage so that the finishing units can be turned in different directions, whereby the reaction force received from the concrete surface can be offset. This concrete floor finishing machine consists of a carriage (A), and a plurality of finishing units (X) arranged on the outer side of the carriage (A) via a connecting means (23). The finishing units (X) can be moved relatively in the vertical direction with respect to the carriage (A), and at least one of the finishing units is adapted to be turned in a direction opposite to the direction in which the other finishing units (X) are turned. Each of the finishing units (X) consists of a plurality of trowel type members (7), which extend radially with respect to the carriage (A).
