2. Description of the Related Art Conventionally, in the case of concrete floor construction, if there is rain during the placement or finishing of the concrete floor, only the concrete placement is tentatively terminated, and after the weather is recovered, the rough concrete surface hit by the rain is removed. It is repaired using a polishing machine. In this repair work, first, a grindstone is mounted on a grinder to grind a protrusion on a concrete surface to flatten it, and then a wire brush is replaced on the grinder to remove contaminants such as latencies accumulated in the concave portions. In the above conventional polishing machine operation, the work is not progressed with a small polishing machine, and the rotation reaction force of the grindstone or wire brush is large with a large polishing machine, which causes heavy labor for workers and generates a large amount of dust accompanying polishing. This was unfavorable for worker hygiene. In addition, the work is a two-step process of grinding concrete surface protrusions by attaching a grindstone and removing impurities such as latence accumulated on the inner surface of the recess by replacing the grindstone with a wire brush. Was twice as long.

The operation of the self-propelled concrete casting floor treatment machine 1 having the above configuration will be described below. First, the floor treatment machine 1 is suspended at a floor concrete casting site using a crane or the like.
A rotating grindstone 15 and a rotating wire brush 16 are mounted on each output shaft of the grinding motor 10. Depending on the condition of the concrete casting floor surface, two of the three floor surface grinding motors 10 may be equipped with the rotating grindstone 15 and the remaining one with the rotating wire brush 16, or vice versa. Either the rotating wire brush 16 is attached to the motor 10, and the rotating grindstone 15 is attached to the remaining one. Thereafter, the engine 7 is started, and the worker separates from the airframe, takes an appropriate monitoring position, issues a work command to the floor processing machine 1 by the remote controller, and

The pressing force of the rotating grindstone 15 and the rotating wire brush 16 and the contact angle with the concrete casting floor surface are controlled to adjust the concrete surface projection by the rotating grindstone 15 corresponding to the unevenness of the concrete placing floor surface. The grinding operation and the operation of removing contaminants such as the latency of the concave portion by the rotating wire brush 16 are performed simultaneously. Although a large amount of dust is generated by the above operation, the worker is away from the machine body and is protected from dust-induced health problems. When the floor processing machine 1 comes into contact with a pillar of a structure or a material placed on the floor, the obstacle detection touch sensor 22 and the emergency stop touch bar 23 attached to the guard frame 21 detect this and detect the floor. Since the processing machine 1 is brought to an emergency stop, the floor processing machine 1 and the collision object are prevented from being damaged. In the above-described embodiment, the example in which the three grinding motors 10 for mounting the rotating grindstone 15 and the rotating wire brush 16 are provided is described.
Of course, there may be no less than three, and in this case, the underframe has a polygonal shape or a disk shape according to the number of motors.
