The seven prefabricated English abbreviations will be OUT if you don’t know it!

1. OS development trend

At present, the prefabricated construction technology of various countries is still the closed system (CS) around the world. The existing production focus is on standardized components and coordinated with standard design and rapid construction. But the shortcomings of CS are the limited structure, lack of flexibility in design, and no popularization of modularity. "The technological development trend of the world's future prefabricated buildings is to transform and develop from a closed system (CS) to an open system (OS)." German architect Charles Mies believes that "OS development trends can be dedicated to the development of standardized functional blocks, Uniform modulus in design; this is easy to be unified and full of changes, which facilitates production and construction, and also brings more and greater assembly freedom to designers and builders."

2. PS/SID development trend

At present, the modular structure design of prefabricated buildings is developing relatively fast in various countries. The future world prefabricated buildings will develop towards the PS/SID integration of prefabricated structure (PS) and systematic interior decoration (SID). Japanese architect Fumihikomu pointed out, “Because prefabricated buildings are not only the industrialization of the main structure, but also the industrialization of interior decoration parts, the two complement each other and rely on each other. It is wrong to one-sidedly emphasize any one of them.”

3. Development trend of UFCS

German architect Wagen Feld said: "The use of the most advanced technological methods to develop a connection point has become the most basic innovative task of the prefabricated construction industry in the future, which will determine the final characteristics of a structure to a large extent. "In the German prefabricated construction industry, the construction work methods related to connection assembly are mainly wet system and dry system. However, the wet system has lower standards and requires more labor. The dry system is a combination of screws and nuts. The disadvantage is that it has poor seismic performance and no wet system has good anti-seepage performance. The German prefabricated construction industry is innovating and developing a universal flexible connection system (UFCS) that uses a combination of cast-in-place and prefabricated assembly. Using UFCS, virtual excitation and other methods can be used to analyze and determine the frequency ratio, damping ratio, and mass ratio of the connecting components. The significant effect is that it can arrange the prefabricated production of the required parts in time according to the assembly needs of the assembly operation, thereby shortening the production. Cycle, reduce the inventory of blanks and products, also improve the utilization rate of assembly components, reduce direct labor, and improve the consistency of assembly components and construction quality, which can significantly improve the economic effect.

4. WICIP development trend

"In the future, the world prefabricated construction industry will surely realize the information management and application of the entire industry chain, and build the information in the consultation, planning, design, construction and management of various links in the industrialization of prefabricated buildings through LAE, CAE, BIM and other information technologies. Exchange platform to realize the support of the whole industry chain information platform (WICIP).” Italian architect Le Corbusier pointed out that “promoting the industrialization of sustainable prefabricated buildings with “modern informatization” is the realization of the prefabricated building industry. An important means for the traceability management of the entire life cycle and quality responsibility."

5. GSAS development trend

The green structural assembly system (GSAS) is a symbol of the industrialization and modernization of the prefabricated construction industry. The new green structural assembly system will inevitably be widely used in future prefabricated houses and buildings. At present, developed countries are paying attention to the development of a new green assembly component system based on composite light steel structure, steel/plastic structure, biomass/wood structure, etc. The goal is to make prefabricated houses and buildings from design, prefabrication, transportation, assembly In the entire housing life cycle of end-of-life treatment, the impact on the environment is the smallest and the resource efficiency is the highest, making the component system of housing and building develop in the direction of safety, environmental protection, energy saving and sustainable development.

6. IAM development trend

At present, the demand for labor resources in the world's construction industry is becoming more and more scarce, especially the construction site of prefabricated buildings, which requires a large number of workers such as hoisting, handling, assembling and connecting. The construction industry in Japan, Germany and the United States are working on the development of intelligent assembly mode (IAM) to reduce the labor resources on the construction site. The way out is to continuously invent and promote robots, automatic devices and intelligent assembly lines, and at the same time innovate and adopt high-value-added products. Prefabricated components and parts eliminate the need for a lot of dirty and cumbersome manual labor on the construction site. This intelligent assembly mode greatly saves human resources than the previous construction mode, while shortening the construction period and improving construction efficiency.

7. Development Trend of NCAB

With the rapid development of the Internet, it will bring new changes to the world's construction industry in the customization and networking of prefabricated buildings. "The main models of future network-based custom fabricated buildings (NCAB) include: networking within the customized environment, realizing the residential assembly of the customized process; networking of the customized environment and the entire assembly enterprise, and realizing the customized environment and the enterprise industry chain information system, etc. The assembly transaction of each subsystem; the networking of the industrial chain between enterprises and the realization of the sharing, combination and optimal utilization of prefabricated houses and construction resources among enterprises; through the network, the realization of customized prefabricated houses in different places." Germany Dams Franz Lampard, architect of the Dart Institute of Prefabricated Buildings, pointed out that “the depth, breadth and development speed of the customized network of German prefabricated buildings in the future will often far exceed the predictions of people in other EU countries.”
