The SI system completely separates the main structure system (skeleton) from the indoor decoration and equipment filling system (infill).

This is easy to be unified and rich in changes, facilitates production and construction, and brings more and greater freedom of assembly and construction to designers and builders.

Because the service life of the skeleton is generally long, and the equipment for decoration and residence is aging rapidly, if the equipment cannot be modified and renovated, the building will not be able to continue to use.

While the main structure system emphasizes the durability and safety performance, the decoration and equipment pay attention to the flexibility and convenience of renewal and transformation.

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 precast steel structure housing.

The industry standard technical standard for precast steel structure residential buildings was also officially implemented on October 1st, 2019.

Information technology runs through the whole industrial chain.

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 keynote for the implementation of the outline.

It is believed that in the near future, a mature Si suitable for precast buildings will be formed [S is the skeleton – the main structure of the building; I is the infill, including building decoration materials, electromechanical equipment, pipelines, etc.

The two complement each other.

We believe that in the future, the construction system and industry of the construction industry will surpass the scope of the existing model and industrial form, realize assembly and industrialization, and gradually enter digital construction and intelligent construction.

In the future, it will be the integrated development of precast building structure and decoration.

The precast steel structure residence has the characteristics of modularization and standardization.

Green is the most important symbol of precast buildings.

Green modular buildings are the most important symbol of the development of building industrialization and industrial modernization.

With the continuous integration of Internet technology and the construction industry, precast buildings can also be customized in the future.

The new green modular building system is bound to be widely used in future buildings.

Let’s look forward to the ten trends in the development of precast buildings in the future.

BIM, GIS, cloud computing, big data, artificial intelligence, Internet of things, robots and other technologies will bring great changes to the traditional construction industry..

The disadvantages are low integration, limited structural form, lack of flexibility in design, and no promotion of modularization.

With the rapid development of industrial Internet, it will bring a new change in the network of precast building customization to the construction industry.

The future technology development trend is to change from a closed system to an open system.

At present, China is dominated by enterprises and research institutions’ respective R & D systems, and the technology is still a closed system.

However, with the impact of environmental protection, population, technology and other factors, the tide of reform in the construction industry has come.

Relatively speaking, the construction industry is still in the era of “handicraft industry”, and the industrialization level is low.

It can be committed to developing standardized function blocks, unified modules in design, and personalized integration.

Compared with other construction methods, it has more obvious comprehensive advantages.

Of course, the cost of personalized customization is closely related to the scale of the building.

Its goal is to minimize the impact on the environment and maximize the resource efficiency in the entire building life cycle from design, production, transportation, construction, use to scrap disposal of precast buildings, so as to make the building component system move towards safety, environmental protection Energy conservation and sustainable development.

Modular, standardized and integrated precast building system will be formed.

In the twinkling of an eye, it is 2022.

At present, developed countries are paying attention to the development of new green assembly building systems mainly composed of composite structure system, steel structure, steel / plastic structure and wood structure.

Precast decoration will reshape building decoration precast building is not only the industrialization of the main structure, but also the industrialization of interior decoration.

The construction industry is one of the three high energy consuming industries, which must practice the road of green development.

China and some developed countries have been committed to the R & D and promotion of Si (skiletoninfill) system in recent years.

This concept is to extend the service life of the residence by clearly separating the residential framework and basic equipment from the decoration and equipment in the residence.

It has not only a high degree of industrialization, but also good seismic performance, high building quality and short construction period.

The development of precast buildings and the reform of building industrialization are unstoppable.

Precast steel structure residential station to the new air outlet of the industry China’s newly built precast buildings reached 290million square meters in 2018, while steel structure residential buildings did not enjoy the dividends of the rapid development of the industry.

Since then, the Ministry of housing and urban rural development has successively approved seven provinces to carry out the pilot of precast steel structure housing.

After years of rapid economic development, the industrialization level of various industries has risen rapidly.

In the future, the main modes of network-based customized precast buildings (NCAB) include: networking in the customized environment to realize the residential assembly in the customization process; The customization environment and the whole assembly enterprise are networked to realize the assembly transaction between the customization environment and the enterprise industrial chain information system and other subsystems; 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.

With the gradual improvement of the standard system, technical system and supporting policies, the steel structure residence will stand at the new wind of industry development in the future.

At present, the main structure of precast buildings in China is mainly promoted, and the decoration is almost forgotten.

According to the traditional thinking of personalized customization, precast buildings may have a unified style.
