by Summary: 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 are gradually localized, so that the higher the production efficiency of the 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, economic construction cost and shortest construction period.
1 construction status of Industrial Park under the background of China’s vigorous development of prefabricated buildings, prefabricated building technology has rapidly expanded the industrial scale according to local conditions, national policies and the needs of local governments.
Prefabricated building is the development direction of design standardization, production industrialization, construction assembly and management informatization, and is the innovation, transformation and upgrading of the traditional construction industry.
The distribution and construction of prefabricated component Industrial Park in the whole country is the product of building industrialization.
The construction of prefabricated component Industrial Park integrates the whole set of intelligent building system from the park process planning and design, architectural design, construction drawing design, civil construction and industrial park operation.
At present, the whole construction process of prefabricated component Industrial Park has some problems, such as nonstandard park planning, excessive configuration of process design, too conservative architectural design, long construction period and uncontrollable cost.
2 significance of the research: the standardization of prefabricated component Industrial Park is the standardization system of industrial park with the greatest economic benefit designed by analyzing and summarizing the industrial park based on the statistics and analysis of the status quo of the built park from the aspects of 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 the existing factories, with a land scale of about 90 mu, in order to provide a reference for the design and construction of municipal scale industrial parks.
The planning and architectural design of the industrial park are required to serve the production, which originates from the industrial division, process design and operation requirements.
3.1 standardization of process design the process design of the standardized industrial park provides the most economical and applicable configuration for the industrial park planning through comparative analysis from the perspectives of standard production line, production process, technical parameters and equipment configuration.
The process design is based on the principles of economy, safety and applicability.
The functional division shall be clear, and the size, height and layout of production, line side, storage yard and workshop shall be considered; Analyze and calculate the capacity demand of each prefabricated component type; And reasonably plan the personnel and sites 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 demand of the local market for different types of prefabricated components; And reasonably configure the production line according to the development strategy of the enterprise.
The logistics shall be smooth and convenient, the overall logistics channel shall realize the diversion of people, the entrance and exit of the park shall be reasonably planned, and the logistics transportation in the park and the external traffic organization shall be reasonable; The logistics route in the park shall follow the principle of shortest route.
The storage yard shall be planned economically, and the storage yard area, equipment configuration and other specifications and quantities shall be reasonable.
Complete auxiliary facilities, energy conservation and environmental protection.
3.1.1 the planning of the standardized industrial park makes statistics and Analysis on the current situation of the built park from the aspects of municipal planning requirements, land use, park planning, building composition, area ratio, building functions, cost optimization, etc.
on this basis, the industrial park is classified.
The functional sub areas mainly include production area, comprehensive building (office, dormitory, canteen, etc.), thermal energy center, sand and stone storage room, guard room, storage yard, road, etc.
The spatial 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 jointly form the standard factory of the industrial park.
According to the production demand, the standardized plant layout design can accommodate the 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, internal partitions, shear walls, sandwich wallboards, truss laminated plates, prestressed laminated plates, stairs, balconies, louvers and other prefabricated components.
3.1.3 logistics planning: the logistics of the park shall fully consider the production and transportation relations in the production process.
According to the characteristics of the added material assembly combination of the prefabricated component production line, priority shall be given to the passing type without turning, so as 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 economic efficiency of plant construction in the production area.
3.1.4 production process: the standard process flow of each standard production line and the process flow of double cycle comprehensive production line: formwork cleaning → formwork installation → reinforcement frame binding → embedding → pouring and tamping → roughening (summer) → pre curing → polishing / roughening (winter) → entering the curing kiln for curing → formwork removal → lifting the long-line formwork production line process: mold cleaning → spraying release agent → embedded preparation → formwork assembly → rebar installation → embedded parts installation → production self inspection → concrete pouring → post-treatment → curing → formwork removal → lifting the fixed formwork production process: formwork cleaning → formwork installation → rebar installation → embedded parts installation → pouring and tamping → curing → demoulding → inspection → defect repair → formwork removal → lifting (3.1.5) The key technical parameter of the production line is the capacity.
Annual capacity = mold area × Table mold utilization rate × Work shift system × Output modulus / number of molds × Annual working days × The calculated thickness of components is 3.2 the planning and architectural design of the industrial park for standardization of architectural design serve the production and come from the industrial division, process design and operation requirements..
