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.
