When a flexible vibrator that transmits the rotary motion of the prime mover to the vibrating shaft inside the vibrating body through a flexible shaft is used for compacting concrete at a civil engineering work site, the flexible shaft may be dragged or damaged by impact.
The outer skin deteriorates due to direct sunlight, or concrete adheres to the outer surface, requiring a great deal of time and effort to clean it after use.Also, when scraping concrete adhering to the outer surface of a flexible shaft, the outer skin may deteriorate. Frequently, a flexible shaft with a damaged outer skin must be replaced with a new one.

The purpose of this invention is to avoid directly attaching concrete to the outer surface of the flexible shaft.
To eliminate the need for cleaning the outer surface of a flexible shaft after compaction of concrete, and to prevent damage to the outer skin of the flexible shaft to eliminate the need for its replacement.

In the rod-shaped vibrator for concrete according to the present invention, a protective coating of removable paint is applied to the outer surface of the flexible shaft that transmits the rotational motion of the prime mover to the vibration shaft in the vibrating body, thereby preventing concrete from directly adhering to the outer surface of the flexible shaft. It is configured so that there is no such thing.

In the drawings of the embodiment, 1 is a prime mover such as an engine or a motor, 2 is a flexible shaft that transmits the rotational motion of the prime mover 1 to a vibration shaft 4 in a vibrating body 3, and 5 is a flexible shaft 4 by spraying or hand painting. This is a protective coating of removable paint formed on the outer surface of the holder, and is preferably made of a rubber-based coating that is highly flexible and elastic. 3 is a cylindrical vibrating body inserted into the concrete, and 4 is a vibrating shaft whose root portion 4a is supported in a cantilevered manner within the vibrating body 3 and connected to the flexible shaft 2. As a result, the tip portion 4b causes a swinging motion, which becomes impact vibration force by the vibrating body 3 and acts on the inside of the concrete. In this way, appropriate vibration is applied, voids inside the concrete are removed, and the strength of the concrete is increased.

ト２の外面に形成させればよいのである。
In the vibrator of the present invention, the outer surface of the flexible shaft 2 is protected by the protective coating 5 made of releasable paint, so even if it is used for compacting concrete at a civil engineering work site, concrete will not adhere to the outer surface of the flexible shaft 2. It will not be attached directly, but will be attached to the protective coating 5.
Therefore, after use, it is only necessary to peel off the protective coating 5 to which the concrete has adhered, and there is no need to scrape off the concrete as in the conventional case. When the vibrator is to be reused, a protective film 5 of removable paint may be formed on the outer surface of the flexible shaft 2 by spraying or hand painting.

の使用に耐え得るのである。 Furthermore, even if the flexible shaft 2 is dragged or subjected to impact, it is protected by the protective coating 5, so unlike the conventional case, the outer skin of the flexible shaft is damaged and must be replaced with a new one. This will not happen, and especially if a tough rubber-based removable paint is used, it will have excellent abrasion resistance, impact resistance, salt resistance, corrosion resistance, etc., and the outer skin of the flexible shaft 2 will be strongly protected. They will be forced to do so. Even if the flexible shaft 2 is exposed to the hot sun while the vibrator is in use, the protective coating 5 blocks the solar heat, so the flexible shaft 2 can withstand long-term use without deterioration of its outer skin.
