Standardized design refers to the design phase, which is aimed at universal products, adopts common conditions, formulates unified standards and models, and carries out a relatively wide range of applicable designs. It is suitable for product designs that are technically mature, economically reasonable, and have sufficient market capacity. The advantages of using standardized design are: ① ensuring design quality, which is conducive to improving engineering quality; ② Can reduce repetitive labor and accelerate design speed; ③ Beneficial for adopting and promoting new technologies; ④ Facilitate the industrialization, assembly, and construction mechanization of component production, improve labor productivity, and accelerate construction progress; ⑤ Beneficial for saving construction materials, reducing project costs, and improving economic benefits..

The integrated design of building structural systems, peripheral protection systems, equipment and pipeline systems, and interior systems is called integrated design. Prefabricated buildings emphasize integrated design, and in the design process, the structural system, peripheral protection system, equipment and pipeline system, and interior system should be comprehensively considered for integrated design. Systematicity and integration are the basic characteristics of prefabricated buildings. Prefabricated buildings are based on complete building products, providing high-performance complete building products. Through the method of system integration, the entire process of design, production, transportation, construction installation, and maintenance is integrated. In prefabricated building design, the design and application of integrated systems have become a development trend. The centralized design of equipment and electrical pipes has advantages over traditional methods. In residential systems, separating long-lived structural systems from short-lived equipment pipeline systems and integrating equipment pipeline wells into public spaces is also a rational trend in residential design, providing the possibility of extending building life through pipeline updates throughout the entire lifecycle of the building.

The Beijing Municipal Building Energy Conservation and Carbon Reduction Work Plan and the 14th Five Year Plan for Green Development of Civil Buildings clearly states that by 2025, the proportion of newly constructed prefabricated buildings will reach 55%; Promote ultra-low energy buildings, and by 2025, the cumulative scale of ultra-low energy buildings promoted in the city aims to reach 5 million square meters.

The Housing and Urban Rural Development Commission has issued the “14th Five Year Plan” for the construction industry, which clearly states: to reasonably layout prefabricated buildings, improve industrial chain construction, do a good job in overall layout, build industrial platforms, and increase promotion efforts.

The 14th Five Year Plan for Prefabricated Buildings in Shanghai has been issued, which clarifies that by 2025, through government guidance and market regulation, we will improve the system, technology, production, construction, and supervision of prefabricated buildings that are suitable for Shanghai’s characteristics, making prefabricated buildings the main construction method in the Shanghai area.

The release of the 14th Five Year Plan for Housing and Urban Rural Development emphasizes that by the end of the 14th Five Year Plan, the proportion of newly built green buildings in urban areas will reach 100%, and the proportion of newly built prefabricated buildings will reach 30%.

The Implementation Opinions on Improving the Quality Assurance System and Enhancing the Quality of Construction Projects have been issued, which clearly states that the concept of green development should be fully reflected, and prefabricated buildings, green buildings, and ultra-low energy buildings should be promoted in a coordinated manner; Highlighting the advantages and characteristics of prefabricated buildings, promoting prefabricated interior decoration, and promoting new construction methods; Carry out demonstration of prefabricated ultra-low energy building projects, pilot the construction of steel structure prefabricated residential buildings, and study and practice the construction of prefabricated rural houses.

The Implementation Plan for the Construction of New Urban Infrastructure in Liaoning Province has been issued, which specifies that by the end of 2025, the proportion of prefabricated buildings in the new construction area in the province will reach 30%.

The policy and technical system for intelligent construction and construction industrialization in the province have been basically established, and the level of construction industrialization, digitization, and intelligence has significantly improved. A group of intelligent construction advantage enterprises have been cultivated to develop new models of rural housing construction. We have a deep understanding of the simple wishes of the Chinese people since ancient times, which condense the people’s beautiful memories of rural areas. Housing safety is closely related to everyone, and the construction quality and safety of self built houses are often difficult to guarantee..

Data shows that since 2000, there have been over 20 publicly reported safety accidents in self built houses, resulting in over 110 deaths. Among them, most of the collapsed houses in rural areas are made of brick and concrete structures..

In fact, in most countries, single family homes, like in rural China, belong to self built houses..

What’s different is that we are still widely using brick and concrete structures. In the traditional construction process, there are common problems such as lack of design drawings, non-standard construction techniques, and uneven material quality. Most of the houses are not designed by anyone, so we either follow the design of others, listen to the simple design of the foreman, or design ourselves. However, lacking professional experience, the houses designed and built are prone to problems of all sizes; All of these may cause hidden risks to the quality and safety of the house. Or you can buy blueprints and hire guerrilla teams for construction. The level of rural construction teams varies, and the houses built are completely different from the design blueprints..

In foreign countries, prefabricated housing has become the mainstream of rural housing construction, replacing red bricks with prefabricated building materials and on-site wet operations with intelligent construction methods, greatly reducing construction time. It also has significant advantages in environmental protection, energy conservation, safety, comfort, and other aspects..

Prefabricated buildings have many advantages, but they are mainly used in urban high-rise buildings in China and have not brought housing upgrades to rural residents. Today, we will help you gain a deeper understanding of prefabricated housing, hoping to be helpful to homeowners who want to build houses. Using intelligent construction to promote the high-quality development of prefabricated buildings is a construction method that is based on factory production, decomposing buildings into standardized components and parts, then producing them in the factory, and finally assembling them on the construction site. This method can greatly improve construction efficiency, reduce construction costs, and also ensure building quality..

We can imagine pre made components such as beams, slabs, columns, and walls as LEGO blocks, and simply assemble them together at the construction site. “Assembly” is not just about “assembly”. After the prefabricated components are transported to the construction site, they will be overlapped and poured with reinforced concrete. This “industrialized” and “industrialized” construction has been widely adopted in Europe, America, and Japan..

#Prefabricated Building # – Building houses like building blocks.

★ What is prefabricated housing, intelligent construction, and new productivity ★.

Prefabricated housing refers to the process of prefabricating some or all components of a residential building in a factory, transporting them to the construction site, and assembling them through reliable connections..

All construction of traditional residential buildings must be completed on the construction site, while prefabricated residential buildings can be produced in factories and installed on the construction site..

For example, your balcony, bay windows, and stairs have all become parts of the factory and need to be integrated in advance. When building the house, they can be directly hung up and assembled..

Even the floor slabs, columns, and beams are pre made in the factory and only need to be installed on the construction site, but this tests accuracy and cannot have any errors..

After the prefabricated stairs, exterior walls, etc. are transported to the construction site, they also need to be overlapped with reinforced concrete, not simply connected. Steel bars run through every structural component such as floor slabs and columns, making the building structure very sturdy..
