Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floor finishing method for automatically leveling concrete placed on a floor surface, and a floor finishing device used therefor.

(Prior Art) When finishing the surface of a concrete slab, it is necessary to level the floor immediately after pouring the concrete, and then level the floor many times over a long period of time to see how well the water is drained. This work is labor intensive and requires manual labor, and it takes time for the concrete to dry, so depending on the time of day the concrete is poured,
Floor leveling work may extend into the night. And the drying time is different in summer and winter, especially in summer, drying is fast.
It had to be completed quickly and required a lot of manpower. In winter, it was difficult to continue floor finishing work using water for long periods of time, and work efficiency was also reduced.

In addition, before floor finishing work, mark levels are set to check the flatness of the finished product.

At that time, it is easy to set a certain level on the surrounding walls, but in the center of the floor surface, when pouring, reinforcing bars etc. are erected to set the level in places and mark it. However, when the intervals between the set levels are large, the intuition of a skilled worker is required, and furthermore, in the final stage of floor finishing, no markings are allowed to be left, so in the end, one has no choice but to rely on intuition. Therefore, it was difficult to ensure the flatness of the floor surface, especially when the floor area was large. (Problem to be solved by the invention) As mentioned above, conventional floor finishing work requires a lot of manpower and Skilled techniques were required to finish a wide range of floor surfaces uniformly and flatly. Therefore, the work cannot be completed without skilled workers, and the intuition of skilled workers is required when setting the level, making it difficult to ensure the flatness of the floor surface.The present invention addresses the above circumstances. The purpose of this invention is to provide a floor finishing device that does not require level setting on walls, etc. and can be operated by one person, and a quick and reliable floor finishing method.

(Means for Solving the Problems) In order to solve the above problems, the floor finishing method of the present invention grips a structure with a gripping mechanism configured at one end of a telescoping boom, and then attaches the structure to the other end of the boom. A floor finishing mechanism is provided, and the floor finishing mechanism is operated in close contact with the poured concrete surface by extending and contracting the boom to finish the floor surface, and the floor finishing device grips and holds the structure. A gripping mechanism is constituted, a telescopic boom is rotatably attached to the gripping mechanism, and a floor finishing mechanism for finishing the concrete surface is tiltably attached to the other end of the boom. Further, the boom may be composed of a first boom and a second boom, and both booms may be formed to be bendable with respect to each other.

(Operation) The structure is gripped by the gripping mechanism and the floor finishing device is set at a predetermined position. Adjust the boom angle by extending and retracting the boom according to the distance to the floor and work range.

Then, the trowel part of the floor finishing mechanism is moved to smooth the floor surface. This floor finishing work can uniformly level a wide area by appropriately adjusting the boom angle and boom length.

Furthermore, when the floor finishing mechanism is moved to a remote location on the floor surface, this can be handled by changing the boom angle and boom length.

(Embodiment) FIG. 1 is a front view of a first embodiment of the floor finishing device of the present invention. The floor finishing device 1 includes a gripping mechanism 7 that grips structures such as beams 30 and columns 40, and a telescopic boom 6 that connects the gripping mechanism 7 and the floor finishing mechanism 2.

The floor finishing mechanism 2 smoothes the floor surface F on which concrete is placed, and includes a plurality of drive units 3, is fixed to each axis of the drive unit 3, and rotates or moves horizontally on the floor surface. It consists of a soldering iron part 4. Note that this drive section 3 and iron section 4
The number of is arbitrary.

A telescopic boom 6 is pivoted to the upper part of the floor finishing mechanism 2 so that it can be raised and lowered freely. The elevation angle λ of the boom 6 can be adjusted as appropriate using a fluid pressure cylinder (not shown). Also,
A rotating section 5 may be provided above the floor finishing mechanism 2. In that case, the floor finishing mechanism 2 can rotate around the center of the rotating part 5.

A gripping mechanism 7 attached to the upper end of the boom 6 has a gripping portion 8
and a rotating section 9. The gripping portion 8 includes gripping claws 8a for gripping the structure from both sides, and expansion and contraction of the gripping claws 8a is performed by a built-in hydraulic cylinder.

The boom 6 is pivoted on the lower end of the rotating part 9, and the boom 6 can be rotated by a built-in hydraulic motor, and the lifting angle θ of the boom 6 can be changed by a hydraulic cylinder.

Next, the floor finishing method of the present invention will be explained using this embodiment having the above configuration.

Grip the beam 30 of the building with the gripping claw 8a of the gripping mechanism 7 and finish the floor! 1 to support the whole. Then, the floor finishing mechanism 2 is set to the designed finishing height on the poured concrete.

At this time, the boom 6 is expanded or contracted according to the distance between the beam 30 and the floor surface F to adjust the floor finishing range and bring the trowel portion 4 of the floor finishing mechanism 2 into close contact with the floor surface. After that, when the drive unit 3 is operated, the trowel unit 4 rotates or moves horizontally to finish the concrete surface smoothly. Often, it may be moved in a straight line repeatedly by a fixed width in the lateral direction.

In this way, the floor finishing work is performed by the rotational movement of the boom 6 by the rotating part 9 of the gripping mechanism 7, the expansion and contraction of the boom 6 and changes in the undulation angles θ and λ, and the rotational movement of the floor finishing mechanism 2 by the rotating part 5. This is performed by a combination of driving the soldering iron part 4 by the driving part 3.

In other words, by rotating the rotating part 9 of the gripping mechanism 7 while gradually changing the length of the boom 6 and the undulating angles θ and λ, it is possible to flatten a wide range of the floor surface. .

In this embodiment, the extension and contraction of the boom 6, the undulating angles θ, λ
Adjustment 1 Since the configuration allows all adjustments related to the rotational speed of the rotating section 3 and the drive of the drive section 3 to be remotely controlled by radio control, the work can be easily carried out by an operator without requiring special skills.

In addition, a sensor is placed in the floor finishing mechanism, and this sensor checks the distance to the floor and the finish condition of the floor.
It is also possible to automate all floor finishing work by having a microcomputer process this data.

In this way, the finished height of the floor surface can be accurately maintained at a constant level by machine settings, and the floor finishing can be divided into several steps and carried out unattended depending on the dryness of the concrete. Further, since the floor finishing mechanism 2 is supported by the boom 6, the weight of the floor finishing mechanism 2 is not applied to the floor surface, and there is no fear that the device will be buried in the floor surface F.

Further, by simply changing the overall length Y of the boom and the angle of elevation θ, it is possible to move the device 1 on the floor, and it is also possible to finish two distant locations in succession.
