by Abstract ❖ with the development of the concrete prefabricated building structure system, the concrete prefabricated components gradually tend to be standardized, and all links of the industrial chain of prefabricated buildings gradually become domestic, so that the higher the production efficiency of concrete prefabricated components, the lower the cost, and the higher the construction requirements of the corresponding prefabricated component Industrial Park.
The standardization research of the industrial park is based on the standardization of process design, architectural design and park construction process, Realize reasonable production capacity demand, optimal planning scheme, economical construction cost and shortest construction cycle.
1 current situation of industrial park construction under the background of China’s vigorous development of prefabricated buildings, prefabricated building technology has rapidly expanded the industrial scale according to local conditions, in combination with national policies and the needs of local governments.
Prefabricated buildings take design standardization, production industrialization, construction assembly and management informatization as the development direction, and are the innovation, transformation and upgrading of traditional construction industry.
The nationwide distribution and construction of prefabricated component Industrial Park is the product of building industrialization.
The construction of prefabricated component Industrial Park integrates a whole set of intelligent building system from process planning and design, architectural design, construction drawing design, civil construction and industrial park operation.
At present, there are many problems in the whole construction process of prefabricated component Industrial Park, such as nonstandard park planning, excessive allocation of process design, overly conservative architectural design, long construction cycle, uncontrollable cost, etc.
2 significance of the study the standardization of prefabricated component Industrial Park is a standardized system of industrial park with the greatest economic benefits designed by analyzing and summarizing the industrial park based on the statistics and analysis of the current situation of the built park from various dimensions such as process zoning, land use, building planning and construction cycle.
3 standardization Industrial Park research the standardization 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 design and construction reference for municipal scale industrial parks.
The planning and architectural design of the industrial park are both required to serve production, which comes from the industrial division, process design and operational needs.
3.1 process design standardization standardizes the process design of the industrial park, and provides the most economical and applicable configuration for the planning of the industrial park by comparing and analyzing 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 the functional division clear, and consider the size, height and layout of production, line side, storage yard and workshop; Analyze and calculate the capacity demand of each prefabricated component type; And reasonably plan the personnel and site in the office and living areas to make their work comfortable and life 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 rationally allocate production lines according to the development strategy of the enterprise.
The logistics is smooth and convenient, the overall logistics channel realizes the diversion of people, the entrance and exit of the park are reasonably planned, and the logistics transportation in the park and the external traffic are reasonably organized; The logistics route in the park follows the principle of shortest route.
The storage yard shall be planned economically, and the specifications and quantity of storage yard area and equipment configuration shall be reasonable.
Complete auxiliary facilities, energy conservation and environmental protection.
3.1.1 the 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., and classifies the industrial parks on this basis.
The functional zones mainly include production areas, comprehensive buildings (offices, dormitories, canteens, etc.), thermal energy centers, sand and stone storage rooms, gatekeepers, storage 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.
3.1.2 standard production line and layout standard production line, standard layout and standard size together form the standard factory of 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, standardized design is adopted for its equipment and size.
The types of components produced by the standardization plant include beams, columns, internal partitions, shear walls, sandwich wallboards, truss laminated plates, prestressed laminated plates, stairs, balconies, bay windows and other prefabricated components.
3.1.3 logistics planning the logistics of the park fully considers the production and transportation relations in the production process.
According to the characteristics of the assembly combination of the added materials of the prefabricated component production line, priority is given to the pass through mode without turning, so as to ensure 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 the standard process of each standard production line is the process of double cycle comprehensive production line: formwork cleaning → formwork installation → reinforcement frame binding → embedding → pouring and tamping → roughening (summer) → pre curing → polishing / roughening (winter) → enter the curing kiln for curing → remove the formwork → lift the long-term bench formwork production line process: mold cleaning → spray the release agent → embedded preparation → formwork assembly → reinforcement installation → embedded parts installation → production self inspection → concrete pouring → post-treatment → curing → formwork removal → lift the fixed bench formwork production process: formwork cleaning → formwork installation → reinforcement installation → embedded parts installation → pouring and vibrating → curing → formwork removal → inspection → defect repair → formwork removal → lifting.
3.1.5 technical parameters of the production line the key technical parameter of the production line is the capacity.
Annual capacity = die area × Table model utilization × Work shift system × Output modulus / number of molds × Annual working days × The calculated thickness of the component is 3.2 the planning and architectural design of the industrial park for standardization of architectural design serve production, which originates from industrial division, process design and operational needs..
