After years of rapid development of China’s economy, the industrialization level of various industries has increased rapidly.
The general system adopts the method of stereotyped components.
According to the traditional thinking of personalized customization, prefabricated buildings may have a unified style.
At present, China’s prefabricated buildings mainly promote the main structure, and the development speed of decoration is slow.
At present, China is dominated by the respective R & D systems of enterprises and research institutions, and the technology is still a closed system.
At the same time, strengthen regional cooperation, eliminate cooperation barriers, strengthen the research and breakthrough of core technologies, increase the protection and management of intellectual property rights, and form a prefabricated building technology system and specification system suitable for China’s national conditions.
In the future, it will be the integrated development of prefabricated building structure and decoration.
As economies of scale cannot be reflected, the government needs to formulate goals and tasks, support policies and incentive measures to promote and guide the development of the industry.
All links of prefabricated buildings from design, construction to construction put forward higher professional and technical requirements for employees.
Relatively speaking, the construction industry is still in the era of “handicraft industry”, and the industrialization level is low.
Prefabricated building is not only the industrialization of main structure, but also the industrialization of interior decoration.
The development of prefabricated buildings and the reform of construction industrialization are unstoppable.
In the future, the construction industry will realize the management and application of the whole industry chain informatization, build an information interaction platform in all links of consultation, planning, design, construction and management of prefabricated buildings through information technologies such as Lae, CAE and BIM, realize the whole life cycle informatization and quality responsibility traceability management of prefabricated construction industry, and create new data synergy.
It is a perfect form of industrialization and must be the future development trend.
We believe that in the future, the construction system and industry of the construction industry will surpass the scope of existing models and industrial forms, realize assembly and industrialization, and gradually enter digital construction and intelligent construction.
The goal of the new green assembly building system based on steel structure is to minimize the impact on the environment and maximize the resource efficiency in the whole building life cycle from design, production, transportation, construction, use to scrapping, so as to make the building component system develop in the direction of safety, environmental protection, energy conservation and sustainable development.
In March 2019, the construction market supervision department of the Ministry of housing and urban rural development issued the key points of work in 2019, which required to carry out the pilot of prefabricated steel structure housing.
Establish a standard architectural design system, reasonably plan and control the diversity of prefabricated components, realize the universality and interchangeability of prefabricated components, standardize and modularize different components, and speed up the design speed and construction efficiency.
5 from the prefabricated steel structure residential station to the new air outlet of the industry, the newly-built prefabricated buildings in China have reached 290 million square meters in 2018, while the steel structure residential does not enjoy the dividend of the rapid development of the industry.
With the rapid development of industrial Internet, it will bring new changes in the network of prefabricated building customization to the construction industry.
Construction industry is one of the three high energy consuming industries, so we must practice the road of green development.
The two complement each other.
Redefine “migrant workers”.
With the gradual improvement of standard system, technical system and supporting policies, steel structure residence will stand at the new outlet of industry development in the future.
Since then, the Ministry of housing and urban rural development has successively approved the pilot of prefabricated steel structure housing in seven provinces.
The outline of China’s 13th five year plan puts forward that we must firmly establish and implement the new development concept of innovation, coordination, green, openness and sharing, in which green development has become the main tone for the implementation of the outline.
At this stage, the degree of standardization and generalization of prefabricated building components in China is low.
Form a standardized and standardized industry development system.
Let’s look forward to the ten trends of the development of prefabricated buildings in the future.
Prefabricated decoration will reshape building decoration.
This is easy to be unified and changeable, and convenient for production and construction, and also brings more freedom of assembly and construction to designers and builders.
The previous construction mode of intelligent makeup ratio can greatly save manpower, shorten the construction period and improve the construction efficiency.
It not only has a high degree of industrialization, but also has good seismic performance, high building quality and short construction cycle.
Compared with other construction methods, it has more obvious comprehensive advantages.
Of course, the cost of personalized customization is closely related to the construction scale.
The new green modular building system is bound to be widely used in buildings in the future.
Policy driven to market driven transformation China’s prefabricated buildings are in the initial stage.
To overcome the difficulties in design, production and construction of clothing matching buildings, we must promote integrated construction and promote the development of EPC.
Therefore, it is particularly important to have a professional and cooperative general contracting team, and implement an integrated modern enterprise operation management mode in R & D and design, component production, construction assembly, operation management and other links, It can maximize the optimal allocation of resources in the integration of design, production, construction and management, and maximize the overall benefits.
In 2019, China Employment Training and technical guidance center released the new vocational information publicity, and the prefabricated construction workers were impressively listed.
With the continuous integration of Internet technology and construction industry, prefabricated buildings can also be customized in the future.
However, with the influence of environmental protection, population, technology and other factors, the tide of reform in the construction industry has come.
In the future, the trend of the first mock exam is to change from closed system to open system.
Integrated construction and EPC is the general trend.
It is more conducive to a highly mechanized and automated process.
At present, China’s construction industry mainly depends on “migrant workers”, but with the disappearance of the demographic dividend, this advantage will become a short board.
6 information technology runs through the whole industrial chain, including BIM, GIS, cloud computing, big data, artificial intelligence Internet of things, robots and other technologies will bring great changes to the traditional construction industry.
9.
Compared with the traditional cast-in-situ, the fabricated construction will significantly reduce the number of on-site operators.
4.
The fabricated construction will require workers in the part production workshop and new labor such as transportation, hoisting, assembly and connection.
1 green is the most important symbol of prefabricated buildings.
Based on the standardization and universality of component components and connection technology, the components produced by a component factory can be exchanged and used among various types of houses.
With the continuous improvement of the employment supervision system and the gradual change of production mode, the term “migrant workers” will become history and will be transformed into construction workers in the future.
Green modular buildings are the most important symbol of the development of building industrialization and industrial modernization.
It can be devotes to developing standardized function blocks, designing unified modules, and integrating personalization.
Even so, at this stage, in the actual implementation of prefabricated buildings, there are still many difficulties in the short term, such as rising costs, extension of construction period, wait-and-see developers, lack of construction experience, lack of technical reserves, system to be improved and so on..
The industry standard technical standard for prefabricated steel structure residential buildings was also officially implemented on October 1, 2019.
The general system is suitable for the specialization and socialization of the production of organizational components and parts.
Fabricated steel structure residence has the characteristics of modularization and standardization.
The main modes of network-based customized prefabricated building (NCAB) in the future include: networking in the customization environment to realize the residential assembly in the customization process; The customization environment is networked with the whole assembly enterprise to realize the assembly transaction between the customization environment and various subsystems such as the enterprise industrial chain information system; The industrial chain networking between enterprises realizes the sharing, combination and optimal utilization of construction resources of upstream and downstream enterprises in the industrial chain.
2 form a modular, standardized and integrated system.
The disadvantages are low integration, limited structural form, lack of flexibility in design, and no promotion of modularization.
3.
The demand for labor resources in the world’s construction industry is becoming more and more scarce.
