Floor surface finishing device

Abstract

A floor surface finishing device easy to handle, capable of completing 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 irons (4) adapted to be rotated in a propeller manner by the driving force from a prime mover (3) while contacting a finish subject floor surface (2), and a planar finishing iron (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 rotary surfaces (7) of the rotary irons (4). Further, on the side opposite to the finishing iron (8) of the plane leveling machine (5) is attached an operating handle (9) for the operator to operate the floor surface finishing device (1). The final finishing operation on the floor surface can be performed by placing the floor surface finishing device on the finish subject floor surface, rotating the rotary irons by the prime mover while pulling the operating handle to horizontally move the whole of the floor surface finishing device along the finish subject floor surface in the direction of arrow A.

Description

technical field [0001] The invention relates to a ground troweling device used for final troweling operation on poured concrete ground or mortar ground at a building construction site. Background technique [0002] When using concrete or mortar to construct the ground, the newly poured concrete at the construction site has traditionally been leveled and the ground leveled. After leaving it for a few hours, the ground is generally pressurized using a leveling machine called TROWEL (トロウエル). After that, skilled operators use a trowel (square trowel) to perform the final trowel by hand. [0003] The plane leveling machine used in this ground construction is represented by a plane leveling machine with a rotating trowel that rotates in a propeller shape and a prime mover that drives it (for example, refer to Patent Document 1: Real Kaihei 5-57198 Bulletin No. 2-5, Figure 1)). The general work sequence is to move the above-mentioned leveling machine to the ground to be construct...

Problems solved by technology

Therefore, the reality is that in the final troweling operation, the skilled operator takes a lot of labor and time

[0005] In addition, since the final troweling work must be completed before the concrete or mortar poured at the work site is cured, many skilled workers are required when the ground area to be constructed is large.

However, judging from the recent situation where skilled workers are decreasing, it is difficult to secure them.

[0006] In addition, in the final polishing work, since the worker poses in an unnatural position for a long time, the physical burden on the worker's legs, waist, shoulders, etc. is also enormous.

In addition, skilled workers engaged in final polishing work repeatedly perform such work for a long time, so even after the work is finished, they suffer from chronic back pain or shoulder pain.
