Mould component for rough surface production of precast concrete unit

Abstract

The invention discloses a mould component for rough surface production of a precast concrete unit. The mould component comprises a precast unit production mould and a precast unit rough surface forming template fixedly connected with the precast unit production mould. The number of mechanical equipment and water washing stations are reduced, no dust pollution or slurry pollution is caused, the cost is low, the efficiency is high, the rough surface of a moulded precast unit meets the national standard, and the product quality is good.

Description

Problems solved by technology

The chiseling process uses a chisel machine to process a rough surface on the surface of the prefabricated component. During the construction process, dust is flying, polluting the environment, time-consuming, labor-intensive, low in efficiency, and high in cost.

The sandblasting treatment process uses a sandblasting machine to spray the pouring slurry on the surface of the prefabricated components, but the treatment depth is shallow, and it is only suitable for surface plastering, pasting of waterproof layers or decorative materials, not suitable for connection of structural parts, and dust pollution during construction larger

The napping process adopts manual napping, which is only suitable for making the roughness of the edge retaining surface without mold, the upper surface of the floor, and the upper surface of the beam.

The exposed aggregate agent + water washing process uses the exposed aggregate agent to smear the surface of the prefabricated component, and then wash it with water. The process is complicated, and a special washing station needs to be set up. The waste water needs to be treated before it can be discharged. The cement slurry pollutes the factory environment greatly, which is not conducive to Industrial production
