Figure 1 Jinan CSCEC green building precast concrete component production plant CSCEC Green Building Industrial Park (Jinan) Co., Ltd.
was established in 2017, invested and constructed by China Construction Eighth Engineering Bureau Co., Ltd., and the first Construction Co., Ltd.
of China Construction Eighth Engineering Bureau is responsible for operation and management.
The company takes “green building product R & D” as its core As the main direction, the main business is the in-depth design, production and processing of precast concrete components, and has developed a series of decorative products such as color concrete, transparent concrete and image concrete, as well as new products such as imitation brick hanging board and integrated heat preservation and decoration hanging board.
The company has completed about 300000 cubic meters of prefabricated components and about 150 service projects.
Case application scenario and technical product features – key points of technical scheme the case systematically studies the intelligent equipment, information technology and manufacturing process for prefabricated component production and manufacturing, introduces and develops a variety of intelligent production equipment and auxiliary equipment, develops an integrated workstation for prefabricated component production and manufacturing, and establishes a system integrating data acquisition, process transmission The intelligent factory management platform of comprehensive management has developed automatic reinforcement processing equipment system, concrete maintenance equipment system and concrete production and transportation equipment system.
The case includes 6 precast component production lines and 2 material processing lines, including 3 precast component automatic production lines, 3 fixed formwork production lines, 1 reinforcement automatic processing line and 1 concrete processing line.
The intelligence and automation of the whole production cycle of precast concrete components are realized through intelligent production equipment.
Figure 2 key technologies and innovation points of prefabricated component production line 2 1 The smart factory information platform has been developed, which integrates the functions of Internet collaboration, QR code, data collection and big data processing, and can greatly improve the efficiency of information transmission and work collaboration.
Figure 3 intelligent factory information platform 2 A complete set of prefabricated component production equipment has been developed, and a variety of intelligent automation equipment have been developed.
Through collaborative linkage, an intelligent automatic production system for prefabricated component production has been formed.
The equipment of prefabricated component production line mainly includes: (1) intelligent movable formwork system.
Automatic assembly line is introduced, and the formwork is equipped with alarm system, which can run along the track and warn the safety situation.
(2) Mobile vibrating platform.
After the concrete component is poured, it needs to be fully vibrated.
The traditional vibrating rod is prone to the problems of uneven vibration, insufficient or too long vibration time, resulting in unstable quality.
The R & D and application of mobile vibrating platform can be interspersed with each fixed formwork along the track to assist vibration.
The time is controllable, the amplitude is controllable and the quality is stable.
(3) Intelligent steam curing kiln.
The maintenance of concrete components can affect the quality of components.
The traditional maintenance mode has a long cycle, requires manual operation, and the maintenance environment is unstable.
The introduction of intelligent steam curing kiln with automatic temperature control and tower storage can stabilize the maintenance quality and greatly shorten the maintenance cycle.
(4) Intelligent prestressed tensioning equipment.
The introduction of intelligent prestressed tensioning equipment can automatically tension according to the set parameters through digital control to ensure the stability and reliability of the prestressed tensioning process.
The reinforcement processing equipment mainly includes: (1) automatic reinforcement straightening and cutting equipment.
The introduction of automatic reinforcement straightening and cutting equipment can quickly and accurately straighten and cut the reinforcement and place it in bundles.
(2) Automatic welding equipment for reinforcement mesh.
In order to solve the problems of slow manual binding speed and unstable accuracy of reinforcement mesh, automatic welding equipment for reinforcement mesh is introduced to replace binding with welding, so as to improve the welding speed and accuracy of mesh.
(3) Automatic welding production equipment for truss reinforcement.
The structure of truss reinforcement of laminated plate for floor slab is complex, and manual processing is difficult to meet the requirements.
The introduction of automatic welding production equipment for truss reinforcement, setting parameters on graphical interface and automatic processing of finished products meet the application requirements, with high efficiency and good quality.
Concrete equipment mainly includes: (1) Mixing plant.
DMPC convection planetary mixer is introduced.
After feeding, the bottom of the mixing tank can be completely covered every 5S to reduce dead corners.
The concrete mixing is more uniform and ensures the uniformity of the apparent color of the precast component concrete to the greatest extent, with a daily output of 2000m ³, It can meet the concrete demand when the plant operates at full load.
(2) Storage bin.
The high-level bin mode is adopted to reduce the use of loader.
(3) dust removal equipment.
The storage bin is equipped with dust removal equipment to directly absorb the dust into the dust collector, so as to achieve the purpose of environmental protection and energy saving.
(4) Concrete transportation crane.
The transportation crane runs on two circular closed steel rails and can transport concrete to each production line in the plant to achieve the goal of raw material transportation automation.
(5) Automatic concrete distributing and vibrating equipment.
Automatic concrete distributing machine is adopted for concrete pouring, which speeds up the production pace and improves the production efficiency and component quality.
3.
A prefabricated component quality detection system is developed.
In the production process of prefabricated components, if the cooperation between disciplines in the construction drawing stage is not in place, the precision of deepening design is not enough, and there are problems Errors in production process will lead to the loss of reserved holes, embedded parts or position deviation on the laminated plate..
