Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides compacted concrete after pouring, and
The present invention relates to a concrete floor finishing vehicle for smoothing the surface of a semi-solidified concrete floor after removing water seeping from the upper surface.

Conventional equipment performs the above-mentioned finishing work.

In addition to interlocking and connecting three rotary blades such as blades to the power body of the engine shop drive, a handle is extended from the power body (~, a finish that eliminates unevenness by grounding the blades and driving rotation. There was a machine (product name: Trofel).

However, in order to steer the above-mentioned finishing machine, the power body is tilted with the handle, the ground contact position M of the rotary blade is changed, and the ground reaction force is utilized. It also had the disadvantage of making it difficult to perform highly accurate finishing.

Furthermore, the vibrations of the rotary blades are transmitted to the workers, and the workers are forced to work in unstable positions for long periods of time, which increases the fatigue of the workers and causes occupational diseases.

SUMMARY OF THE INVENTION In view of the above points, it is an object of the present invention to enable the surface finishing work of concrete floors to be carried out accurately, easily, and easily.

In order to achieve the above object, the concrete floor finishing work vehicle according to the present invention is characterized in that a finishing device for smoothing a semi-solidified concrete floor surface is attached to a traveling vehicle body equipped with a driving traveling device. .

This characteristic configuration has the following effects.

In other words, the surface of the concrete floor is finished by the finishing device attached to the vehicle by steering and driving the vehicle.

As a result of the above action, the following effects are achieved.

In other words, by attaching the finishing device to the vehicle body at a predetermined height, the level of the finishing device relative to the concrete floor surface can be maintained at a substantially constant level, and the vehicle body must be steered for steering. It is possible to almost uniformize the ground pressure applied to the concrete floor surface from the finishing equipment without requiring any skill, such as using ground reaction force.
Perform surface finishing work on concrete floors with high precision and
It's easy and I can now do it easily.

Furthermore, by automatically running the traveling device, it is possible to avoid the negative effects on workers caused by minute vibrations transmitted through the finishing equipment, and even if drops are applied to the traveling vehicle body, there will be no negative impact on the workers. In addition, since the operator only needs to steer the traveling device, he or she can work in an appropriately comfortable posture, making it possible to seriously avoid the occurrence of occupational diseases.
