In 2016, several opinions of the CPC Central Committee and the State Council on Further Strengthening the management of urban planning and construction (ZF [2016] No.

The British government clearly stated that the British construction production field needs to achieve the goal of “cost reduction by 10%, time reduction by 10% and defect rate reduction by 20% through new product development, intensive organization and industrial production.

In 1976, the national industrial housing construction and safety act of the United States promulgated a series of strict industry codes and standards, which have been used until now.

The general contracting mode will be adopted to promote government investment projects.

Therefore, the government has issued a series of incentive policies and measures to vigorously promote green and energy-saving buildings; At the same time, the strict requirements for building quality and performance have also promoted the transformation of the industry to a new construction mode.

05 Japan put forward the concept of precast housing in 1968 and introduced the production mode of component and industrialization in 1990.

With the continuous improvement of the top-level system design, the effective implementation of local policies and measures, the precast building technology system is becoming more and more mature, the industrial team is growing, and the project scale continues to grow, creating a good policy environment and market environment for the development of new building industrialization.

Many of its companies serve many industries such as architectural decoration, machinery manufacturing, education and training, import and export trade and so on.

6) proposed to develop new construction methods and vigorously promote precast buildings.

Youngstrong# as a major construction country in the world, China’s annual total emission of construction waste has continued to rise since 2013, reaching 2.38 billion tons in 2017, accounting for 30% – 40% of the total urban waste, causing serious environmental pollution.

In April 2018, in order to meet the growing market demand and provide customers with more professional products and services, Yongqiang (Liaoning) Integrated Housing Co., Ltd.

Next, let’s learn about the development of precast buildings in several major countries.

About Yongqiang Yongqiang enterprise was founded in 1997.

It is the first batch of enterprises producing container modular houses in Northeast China.

Structural components are separated from equipment and decoration works to reduce embedding, green energy-saving production and high construction quality.

was registered and established, focusing on the R & D, production, leasing and sales of container like modular residential products.

was invested and established, which is committed to the R & D, production and sales of new steel structure cast houses and energy-saving and environmental protection building materials.

There were disadvantages such as high energy consumption, high pollution and low efficiency, which did not meet the objective requirements of sustainable development.

According to the statistics of the American industrialized housing association, in 2001, the number of precast houses in the United States reached 10 million, accounting for 7% of the total number of houses in the United States.

In 2011, Yongqiang Technology (Shenyang) Co., Ltd.

This allows the full integration of precast housing and energy-saving standards.

Because the precast building production mode greatly reduces the pollution caused by on-site construction and improves the environmental friendliness of construction, it has become the main direction of construction industry reform.

In the past, urban construction in the process of urbanization was at the cost of consuming a lot of resources and damaging the ecological environment.

So far, the standardization, serialization, specialization, environmental protection, commercialization and socialization of residential components and parts in the United States are very high, almost 100%.

Most of the assembly construction of precast buildings was carried out in factories, which played a significant role in energy conservation, material conservation, water conservation, land conservation and environmental protection, It is very consistent with the concept of green development, which will improve the level of energy efficiency, accelerate the elimination of backward equipment and technology, and promote the transformation and upgrading of the national construction industry.

These products can be widely used in workplaces with special needs such as transportation, water conservancy, petrochemical, power communication, medical treatment, fire control and military; At the same time, it can also meet the requirements of urban office, exhibition, civil resettlement, earthquake relief, temporary construction of construction site and other movable construction facilities; It also provides the best solution for the rapid construction of commercial facilities such as vacation villas, commercial catering and public health in tourist areas..

Germany is the country with the fastest reduction in building energy consumption in the world.

According to the professional skill requirements of the cast construction industry, the UK has established a professional level and skill recognition system to promote the formation of the talent team of the whole industry chain.

01 precast houses were popular in the United States in the 1970s.

In the process of promoting the structural adjustment of large-scale and industrialization, the housing industry has experienced the continuous evolution and improvement process from standardization, diversification, industrialization to intensification and informatization.

04 precast houses in France mostly adopt frame or plate column system, and dry operation is adopted for welding and bolt connection.

France mainly adopts prestressed concrete precast frame structure system, and the assembly rate can reach 80%.

06 China’s precast building market is in the stage of rapid development.

From the central to local, more than 20 provinces and cities have successively issued strong support policies for precast buildings.

It is expected that by 2025, the construction area of new precast construction projects will account for 75% of the new construction area, the assembly rate will reach more than 50%, the full decoration rate of precast construction projects will reach more than 80%, and the standardization rate of parts and components will reach more than 50%.

In recent years, Germany has proposed to develop passive buildings with zero energy consumption.

In the future, the precast construction method will become the main construction method.

The production system of medium and high-rise housing with high production efficiency, low environmental pollution, variable internal structure and meeting the different needs of residents was born.

It has independently developed and produced more than 30 types of container modular products in three categories: residential, commercial and functional class.
