by At 12 o’clock on the evening of August 21, the PC workshop of CSCEC Science and Technology Industrial Park was brightly lit, and the machinery and equipment operated in an orderly manner.
The managers of CSCEC Science and Technology Hunan Co., Ltd.
and the industrial workers of the workshop witnessed the birth of the first PC prefabricated component in the industrial park.
According to the person in charge of the PC workshop, the first PC prefabricated component produced in the industrial park is still in the stage of equipment commissioning and running in.
The design and research personnel have already assembled, and the industrial workers in the workshop have been on duty successively.
The PC prefabricated component board produced at the key station of the PC prefabricated component assembly line will be used for the production of the composite prefabricated pipe gallery recently developed by the company.
Through this new process, the R&D and production of the composite prefabricated pipe gallery will be assisted.
After the PC production line is put into operation, it will provide strong support for the rapid promotion of urban pipe gallery construction.
At the same time, the three prefabricated pipe gallery models developed by CSCEC Technology Hunan Co., Ltd.
will be guided by the government.
As the “star product” of CSCEC Science and Technology Industrial Park, this meticulously constructed production line will continuously provide high-quality products for urban construction.

The PC workshop of CSCEC Science and Technology Industrial Park has introduced PC prefabricated component equipment from famous domestic enterprises, integrated advantages of various technical resources, and jointly promoted the construction of PC production line.
The design size of the PC prefabricated component production line is 248m long, 27m wide and 11m high.
A total of 60 standard mold tables are set in the workshop, and the curing kiln adopts 6 rows, 7 layers and 42 warehouses, which are fully closed and three-dimensional curing.
A complete set of PC prefabricated component equipment PC prefabricated component automatic assembly line monitoring interface and function diagram At the same time, the assembly line adopts full intelligent automatic operation, integrating ERP software bill of materials entry, central control integrated control, material plate printing, task management, finished product warehousing and outbound, project information management and other functions.
After the formal production, the PC prefabricated component production line will produce 200000 cubic meters of prefabricated components annually.
2PC prefabricated component automation assembly line is roughly divided into 7 main working procedures: cleaning the mold table; Automatic scribing and installation of side die; Installation of reinforcement skeleton and embedded parts; Concrete pouring, vibration, leveling and polishing processes; Curing; Dismantle the side die; Demoulding of components.
Production process flow of inner and outer wall panels • Step 1: Use the mold cleaner to clean up the concrete slag attached to and scattered on the mold, and collect it into the slag bucket.
Automatic cleaning machine • Step 2: automatic scribing and installation of side formwork: input the cad drawings of prefabricated components into the automatic scribing machine control system, and the automatic scribing machine will draw window openings, component outlines, etc.
according to the shape and size of components for installation of side formwork.
The side formwork shall be installed manually with auxiliary tools.
Side formwork installation • Step 3: install the reinforcement framework and embedded parts: after the mold installation is completed, spray the release agent as required, and then install the reinforcement cage, embedded parts and reserved holes.
The fourth step: concrete pouring, vibrating, leveling and polishing after the installation of the reinforcement framework is completed and the inspection is passed.
Automatic vibrating table is used for vibration.
Concrete delivery torpedo tank spiral distributor automatic vibrating table vibrating leveler • Step 5: Centralized low temperature steam curing is adopted for the curing of internal and external wall panels and composite floor assembly lines, and the poured components are transported to the three-dimensional curing kiln with the mold, and the components are stacked to the sixth floor as a whole for steam curing.
The curing kiln is divided into two independent, heat preservation and airtight spaces.
The internal temperature is kept at about 50C °, and steam pipes are used for heating.
Pre curing kiln troweling machine, stacking machine, three-dimensional curing kiln • Step 6: The formwork can be removed and lifted only when the compressive strength of curing test pieces under the same conditions is not less than 75% of the design strength.
Before formwork removal, the members go through sufficient cooling process.
Before lifting, ensure that the members are not connected to the formwork to any extent, and the formwork removal sequence is opposite to the formwork installation sequence, and all fasteners are removed in sequence.
Formwork removal platform • Step 7: After the removal of the formwork, the formwork and the product will be turned over together to about 80 degrees by the turnover machine.
When all the embedded parts are separated, the prefabricated parts will be lifted from the formwork by the crane, placed on the component transport vehicle, and sent to the storage yard by the component transport vehicle.
