Description

Description: TECHNICAL FIELD The present invention relates to a method for moving a concrete floor leveling machine, and more specifically, a method for moving a concrete floor leveling machine in a direction intersecting with a traveling direction thereof. Regarding

(Prior Art) Among the work on the concrete floor, the work before the concrete hardens has been conventionally performed as follows.

First, a reinforcing bar is assembled in a formwork forming a floor surface, concrete is driven into the formwork from a flexible hose or the like, or concrete is driven into a recess corresponding to the floor surface.

Next, if necessary, concrete is filled and compacted with a vibrator or the like.

Next, a worker performs rough leveling while adjusting the excess / deficiency of concrete with a leveling jig.

Finally, the worker performs leveling work on the floor surface, and performs ruler-sliding work such as top-leveling with a ruler bar and work-out.

In such a conventional method, in particular, it is necessary to secure a large number of skilled workers when the floor area is large, because skilled workers are required for the work after leveling. Even if there is, there is a problem that the finishing accuracy varies among workers and that the work takes a long time.

Therefore, the applicant of the present invention can reduce the number of skilled workers, can maintain the finishing accuracy with high precision without causing variations, shorten the construction time, and obtain various types of concrete floor leveling machines that can obtain a good state of shaving. Is proposed. Such a concrete floor leveling machine is provided with a trowel having a predetermined length, a support frame for supporting the trowel, and a traveling means connected to the support frame for traveling the support frame.

Then, the trowel is moved by the traveling means and the support frame in a direction intersecting with the longitudinal direction of the trowel so that the concrete floor surface is mechanically leveled.

(Problems to be solved by the invention) In this case, if the concrete floor leveling machine is configured to run only in the direction of leveling the concrete floor surface with the trowel, the simplification and weight saving of the machine body can be achieved, and It is possible to reduce the cost.

However, when the concrete floor leveling machine is configured such that the traveling direction is one direction, for example, when trying to level the adjacent concrete floor surface in the direction orthogonal to the traveling direction, the concrete floor leveling machine is used. It requires mechanical equipment such as a crane to move, which causes a problem that it cannot be easily moved.

The present invention has been devised in view of the above circumstances, and an object thereof is not to require mechanical equipment such as a crane, but to easily move a concrete floor leveling machine with a simple structure in a direction crossing its traveling direction. The purpose is to provide a method of moving a concrete floor leveler that can be moved.

(Means for Solving the Problems) The configuration of the present invention for achieving the above-mentioned object will be described with reference to the drawings corresponding to the embodiments.

And the long material 71 is arranged below the roller 53 in parallel with the longitudinal direction of the trowel 3, and then the roller 53 is moved downward.
The traveling means 7 is lifted by pressing it against the long material 71, and in this state, the roller 53 is rolled on the long material 71, and the concrete floor leveling machine 1 is moved along the long material 71. By moving the roller 53 upward at the position of, the traveling means 7 is lowered,
The long material 71 is taken out from below the roller 53.

(Operation) No mechanical equipment such as a crane is required, and only two rollers 53 are used.
With the simple structure including means for moving the roller 53 up and down, the concrete floor leveling machine 1 can be easily moved in the direction intersecting with the traveling direction thereof.

Therefore, even if the concrete floor leveling machine 1 is configured with the traveling direction as one direction to simplify, lighten, and reduce the cost of the machine body, it is easy to cross the traveling direction only by adding a simple structure. It becomes possible to move to.

When the concrete floor leveling machine 1 has height adjusting means for the iron 3, the height adjusting means can be used to move the roller 53 up and down to reduce the number of parts and simplify the structure. Can be realized.

Further, if the roller 53 is attached to the vertically moving support frame 5, the height of the support frame 5 together with the roller 53 can be kept low when the leveling machine 1 is moved, so that the leveler 1 can be stably moved.
