The invention discloses a
rapid manufacturing process for a prefabricated power distribution room and a GRC shell. The
rapid manufacturing process comprises various
sizing customized molds and an
assembly type process. The manufacturing process comprises the following steps of manufacturing a standard component reinforcing mesh, namely scientifically designing a reinforcing mesh, stirrups, riveting reinforcing steel bars and binding; mold closing the standard component, specifically, mold closing a positioning pin, fixing and pre-burying the embedded part at a designed position by using a screw; stirring, specifically, in a full-automatic large-scale stirring
station, setting a ratio and stirring time according to environmental conditions; pouring; maintaining, specifically, opening the mold after steam curing, standing after natural maintaining, and standing in a maintaining period; splicing, specifically, splicing through an
assembly type process and a flexible number combination concept, after drawing is conducted, flashes are treated firstly, adopting
bolt connection for splicing, tensioning two components to the maximum extent to enable a gap is infinitely small, and filling the combination face of the components with special structural
adhesive; and performing surface treatment; According to the manufacturing process, long-distance transportation of finished products is not needed, different-place splicing is achieved, the working efficiency is greatly improved, and damage to the products caused by long-distance transportation is reduced.
