Production technology of precast concrete member rough surface

Abstract

The invention discloses a production technology of a precast concrete member rough surface. The production technology comprises the steps that 1, a precast concrete member rough surface forming template is prepared; 2, a precast member flange die is manufactured; 3, the precast member rough surface forming template prepared in the step 1 is connected and fixed to the precast concrete flange die prepared in the step 2; 4, the precast member rough surface flange die obtained in the step 3 is installed on a steel trolley or a bottom template; 5, connecting reinforcement bars are arranged based on the step 4; 6, concrete pouring, vibration, maintenance and demolding are carried out, and a precast concrete member with the rough surface is formed. Mechanical equipment and washing stations are saved, dust pollution and slurry pollution are avoided, the cost is low, the efficiency is high, the precast concrete member rough surface meets national standards, and the product quality is good.

Problems solved by technology

The chiseling process is to use 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 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 plastering the surface, pasting waterproof layers or decorative materials, not suitable for the connection of structural parts, and dust pollution during the construction process 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
