Description

Surface leveling device for building walls}

The present invention relates to a surface leveling device for building walls, and more particularly, to a surface leveling device for smoothing the surface after applying cement mortar to the surface of an inner wall made of bricks.

In general, in construction, after constructing frames and walls, plastering is performed by applying mortar to the surface to obtain a smooth surface. Bar, this requires a lot of manpower and time for the work, so wall plastering has been proposed, but these have not been put to practical use.

On the other hand, in the prior art, a plurality of blade pieces are attached to a chain at regular intervals in a box so that they rotate in one direction, but an opening is formed in front of the rotation direction of the blade piece, and the mortar is moved upward while moving the opening close to the wall surface. A technique has been proposed in which mortar is discharged toward the opening by injection and attached to the wall surface by rotation of the blade, and the tip of the bottom surface of the opening plasters the mortar surface.

In the prior art, there was a problem that a plurality of blade pieces could not withstand the weight of the mortar and were damaged or deformed, resulting in damage to the wall surface and a problem of requiring more time, such as having to work again.
