Rapid manufacturing process for preassembled power distribution room and GRC shell

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of a prefabricated power distribution room and a GRC shell, and specifically refers to a rapid manufacturing process for a prefabricated power distribution room and a GRC shell. Background technique [0002] Prefabricated power distribution room with GRC shell has been widely used in electric power, gas, municipal and other fields; traditional prefabricated power distribution room and GRC shell are made of general-purpose molds, and the mold material is generally made of channel steel. The way of opening and closing the mold is hitting and welding, and the mold is easily deformed by frequent hitting; the pre-embedded parts are made of temporary materials, which are not standard, and rely heavily on welder skills; The requirements are high, the pre-embedded position of the pre-embedded parts cannot be accurately positioned, the riveting effect is poor, and there is no scientific basis; most of the closing mol...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the traditional process has low production efficiency, the inaccuracy of the mold makes the flatness and straightness errors of the components too large, the assembly error is too large, the maintenance period of the components is not enough, the strength and structural force are not good, and the assembly efficiency is low, etc. question
