Description

Multifunctional steel formwork grinding machine

Technical Field

Background

At present, in concrete lining construction, steel templates are generally adopted for matching molds and pouring, such as walls and floors of buildings, side walls and vault roofs of tunnels or underground pipe galleries, piers and bridge bodies of high-speed railways and highways, retaining walls and slope protection of riverways and side slopes and the like. Because the concrete has stronger caking property, after the steel templates are poured and demolded, more concrete residues are bonded on the surfaces of the templates, the templates are uneven, the next pouring quality is influenced, and in addition, the surface of some steel templates can generate more iron rust due to overlong idle time, and the apparent quality of the concrete can also be influenced. Therefore, before the templates are matched, the surfaces of the templates generally need to be polished and cleaned, and repair is needed when the templates are seriously deformed. The manual polishing and cleaning mode not only wastes time and energy and has low efficiency, but also causes personal injury because the worker is close to the polishing surface and splashed concrete residues and scrap iron easily enter eyes and nostrils of the worker.
