Description

Technical Field

[0001] The utility model belongs to the field of indoor decoration, in particular to a concrete roughening mechanism. Background Art

[0002] The concrete surface of wall structural columns, ring beams, etc. is too smooth, and the plaster layer cannot combine well with the concrete. In order to better bond and prevent hollowing, it is necessary to throw slurry to roughen the surface. There are currently two commonly used methods. One is the traditional method, in which a broom is dipped in glue and applied to the wall to roughen the surface. The quality is poor, it cannot meet the ideal quality requirements, and the execution efficiency is low.

[0003] In contrast, the Chinese patent with announcement number CN209538698U discloses a tool for roughening a concrete surface, including a mesh body and an operating handle connected to the mesh body, and the mesh body is subjected to pressure through the operating handle, and the wall is roughened by the horizontal pulling action of the mesh body. The mesh body is pulled on the surface instead of the brush dipping slurry and throwing droplets on the wall, and the mesh body is subjected to movement and pressure through the operating handle, so that the mesh mark is pressed into the concrete surface, thereby increasing the roughness of the wall and completing the roughening.

[0004] However, the above patent lacks a mortar replenishing device, and the mesh racket body needs to be frequently replenished with mortar, which is inefficient. The fixed connection between the handle and the mesh racket body cannot adapt to various working angles. At the same time, the different amounts of mortar replenished to the mesh racket body each time can easily cause uneven hair pulling. Therefore, a new device needs to be designed.
