DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning damping device for cleaning and damping a formwork or a concrete wall used for constructing a concrete wall at a civil engineering work site such as a dam.

[0002]

2. Description of the Related Art Conventionally, for example, when constructing a concrete body in dam construction, a required space is formed by surrounding a plurality of molds, and concrete is poured into the space. Then, after the concrete is solidified, the work of sliding the formwork from below to above and further placing concrete therein is repeated to form the concrete skeleton.

[0003] However, once a concrete form has been used for placing concrete, the remaining concrete remains fixed on the surface of the form, so that it cannot be used as it is for the next concrete placement.

Therefore, a wire brush having a diameter of about 100 mm was attached to a handy type disk grinder, and an operator pressed the wire brush against a formwork to remove concrete residue and the like adhered thereto.

[0005]

By the way, the formwork used in the above dam construction is large, and it is slid up from below along the side wall of the concrete skeleton to be reused by re-use. It is held in a posture or a slightly inclined posture.

[0006] Therefore, in order to clean and squeeze the upper part of the form frame held in such a standing posture or the like, hold the hand-held type disc grinder with both hands and further devote both arms upward. Since it is necessary to perform the work and it is physically painful, it is difficult to perform the work for a long time.

[0007] Further, when the disc grinder is lifted above the body, dust generated from the concrete residue falls on the face and body of the worker, resulting in a poor working environment.

[0008] In addition, a scaffold is required to clean and clean the upper part that cannot be reached by workers.
Cleaning and cleaning in an unstable position on a scaffold is dangerous.

Further, in order to clean and squeeze the lower portion of the formwork held in the standing posture or the like, it is necessary to hold the disc grinder with both hands and work in a bent or squatting posture. In such a case, it is difficult to carry out the work for a long time because physical pain is involved. In addition, the cleaning and cleaning operation using the handy type disk grinder has a low cleaning and cleaning capability per unit time.

SUMMARY OF THE INVENTION The present invention is directed to providing a cleaning cleaning device that can easily and quickly clean a formwork and a wall surface and can prevent scattering of concrete residue and the like to the surroundings. is there.
