by Abstract: With the development of prefabricated concrete building structure system, prefabricated concrete components are gradually becoming standardized, and each link of the industrial chain of prefabricated buildings is gradually localized, which makes the production efficiency of prefabricated concrete components higher, the cost lower, and the corresponding requirements for the construction of prefabricated component industrial parks will be higher.
The standardization research of industrial parks is based on the standardization of process design, architectural design, and park construction process, Realize reasonable capacity demand, optimal planning scheme, economic construction cost and the shortest construction cycle.
1 Current situation of industrial park construction Under the background of vigorously developing prefabricated buildings in China, prefabricated building technology has rapidly expanded its industrial scale according to local conditions, national policies and the needs of local governments.
The prefabricated building is the innovation, transformation and upgrading of the traditional construction industry with the development direction of design standardization, production industrialization, construction assembly and management informatization.
The distribution and construction of prefabricated component industrial park nationwide is the product of building industrialization.
The construction of the prefabricated component industrial park integrates a complete set of intelligent building systems from the park process planning and design, architectural design, construction drawing design, civil construction to the operation of the industrial park.
At this stage, the whole construction process of prefabricated component industrial park has problems such as nonstandard park planning, over allocation of process design, over conservative architectural design, long construction period, uncontrollable cost, etc.
2 The significance of the study The standardization of prefabricated component industrial parks is a standardized system designed to maximize economic benefits based on the statistics and analysis of the current situation of the built parks from various dimensions, such as process zoning, land use, building planning, and construction cycle.
3 Standardized Industrial Park Research Standardized industrial park is based on the technical requirements and market experience of existing factories, with a land scale of about 90 mu, in order to provide reference for the design and construction of municipal scale industrial parks.
The planning and architectural design of the industrial park are required to serve production, which originates from industrial zoning, process design and operation requirements.
3.1 Process Design Standardization The process design of the standardized industrial park provides the most economical and applicable configuration for the planning of the industrial park through comparative analysis of the standard production line, production process, technical parameters, and equipment configuration.
The process design is based on the principles of economy, safety and applicability.
Make functional zoning clear, and consider the size, height and layout of production, line edge, storage yard and workshop; Analyze and calculate the capacity demand of each prefabricated component type; As well as the reasonable planning of the personnel and sites in the office and living areas, so that their work is comfortable and life is convenient.
The production process shall be continuous and smooth, and the rhythm of each process of the production line shall be balanced according to the needs of the local market for different types of prefabricated components; And according to the development strategy of the enterprise, reasonably configure the production line.
The logistics shall be smooth and convenient, the overall logistics channel shall realize the separation of people, the entrance and exit of the park shall be reasonably planned, and the logistics transportation and external transportation in the park shall be reasonably organized; The logistics route in the park follows the principle of shortest route.
The storage yard shall be planned economically, and the size, equipment configuration and other specifications and quantities of the storage yard shall be reasonable.
Complete auxiliary facilities, energy conservation and environmental protection.
3.1.1 Standardized industrial park planning makes statistics and analysis on the current situation of the built parks from various dimensions such as municipal planning requirements, land use, park planning, building composition, area ratio, building functions, cost optimization, etc.
On this basis, industrial parks are classified.
The functional zones mainly include production areas, comprehensive buildings (offices, dormitories, canteens, etc.), thermal energy centers, sand and stone storage rooms, doorkeepers, yards, roads, etc.
The space division is relatively clear, and at the same time, it meets the needs of production and life, so that the production and transportation streamline is simple and lean production.
3.1.2 Standard production line and layout standard production line, standard layout and standard size form a standard factory in the industrial park.
According to the production demand, the standardized plant layout design can accommodate long line formwork production line, double cycle comprehensive production line, fixed formwork production line and reinforced concrete production line.
According to the selected production line, the standardized design is adopted for its equipment and size.
The types of components produced by the standardization plant include beams, columns, interior partitions, shear walls, sandwich wallboards, truss composite plates, prestressed composite plates, stairs, balconies, bay windows and other prefabricated components.
3.1.3 The logistics planning of the park takes full account of the production and transportation relationship in the production process.
According to the characteristics of increasing the material assembly combination of the prefabricated component production line, priority is given to the non transition passing mode to achieve smooth production and transportation and save land.
A series of standardized dimensions are formed according to the production line process, logistics requirements and plant construction economy of the plant in the production area.
3.1.4 Production process Standard process flow of each standard production line Double cycle comprehensive production line Process flow: formwork cleaning → formwork installation → reinforcement frame binding → embedding → pouring and tamping → roughening (summer) → pre curing → polishing/roughening (winter) → Maintenance in curing kiln → Formwork removal → Lifting of long line formwork production line Process: Mold cleaning → Spraying release agent → Embedding preparation → Formwork assembly → Reinforcement installation → Embedded parts installation → Production self inspection → Concrete pouring → Post treatment → Curing → Formwork removal → Lifting of fixed formwork Production process: Mold cleaning → Formwork installation → Reinforcement installation → Embedded parts installation → Casting and tamping → Curing → Demoulding → Inspection → Defect repair → Formwork removal → Lifting 3.1.5 Line technical parameter The key technical parameter of the production line is the capacity.
Annual Capacity=Formwork Area × Table formwork utilization rate × Work shift system × Output modulus/number of formworks × Annual working days × Component calculation thickness 3.2 The planning and architectural design of the standardized industrial park for architectural design serve the production and are derived from industrial zoning, process design and operation requirements..
