Abstract: An apparatus for flattening a half-dry concrete floor includes a plurality of pressure rollers arranged such that axes of them are parallel with one another in an imaginary plane, a holder rotatably supporting the pressure rollers at opposite ends of the pressure rollers, an oscillation-transmitter formed integral with the holder for transmitting oscillation to the pressure rollers, and an oscillator for oscillating the oscillation-transmitter.

Abstract: A floor surface finishing device includes a plane leveling machine having a plurality of rotary blades adapted to be rotated in a propeller manner by the driving force from a motor while keeping in contact with a floor surface to be finished. A planar finishing blade is connected to the planar leveling machine through a connecting member. In this state, the finishing blade is located in a portion of the outer peripheral regions of the planes of rotation of the rotary blades. Further, on the side opposite to the finishing blade of the plane leveling machine, an operating handle for the operator to manipulate the floor surface finishing device is attached.

Abstract: A floor surface finishing device easy to handle, capable of completing a final finishing operation on the floor surface in a relatively short time, and making it possible to reduce the number of operators. A floor surface finishing device (1) comprises a plane leveling machine (5) having a plurality of rotary blades (4) adapted to be rotated in a propeller manner by the driving force from a motor (3) while keeping in contact with a floor surface to be finished (2), and a planar finishing blade (8) which is connected to the planar leveling machine (5) through a connecting member (6) and which, in this state, is disposed in a portion of the outer peripheral regions of the planes of rotation (7) of the rotary blades (4). Further, on the side opposite to the finishing blade (8) of the plane leveling machine (5), an operating handle (9) for the operator to manipulate the floor surface finishing device (1) is attached.
