[0002] Prefabricated buildings refer to buildings that are assembled and connected at the construction site through factory-produced parts and components. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. They adopt standardized design, factory production, assembly construction, information management, and intelligent applications. They are representatives of modern industrialized production methods. Prefabricated concrete structures are a form of building structure. They are mainly composed of concrete components prefabricated in the factory. These components are assembled on site through specific connection methods. This structural form not only increases construction speed, but also reduces material loss, improves production efficiency and project quality.

[0003] During the production of this type of concrete structure, its outer surface needs to be polished. The existing polishing device is to place it on a conveyor belt and move it to change the polishing position. Although this moving method can evenly polish the surface of the concrete structure, there are still problems.

Therefore, a stable mobile concrete polishing machine for assembled buildings is needed. Utility Model Content
