Overall, East China is still the region with the largest number of precast construction projects in China.

The development of precast building regional structure construction industry is inseparable from the support of economic foundation.

The central economic work conference held at the end of 2020 also proposed to further accelerate the promotion of precast buildings.

The construction demand, especially the housing construction demand, will promote the continuous growth of the precast construction industry.

The overall economic development level of East China is high, and has a relatively perfect transportation network.

With the proposal of the development goals of “carbon neutralization” and “carbon peak”, the natural green environmental protection advantages of precast buildings will be further highlighted.

From the perspective of structural form, 430 million square meters of newly started precast concrete structure buildings, an increase of 59.3% over 2019, accounting for 68.3% of newly started precast buildings; Precast steel structure buildings are 190 million square meters, an increase of 46% over 2019, accounting for 30.2% of newly started precast buildings.

Compared with the traditional cast-in-place buildings, the carbon emissions of precast buildings in the production and construction stages of building materials are reduced to a certain extent, so they have been strongly supported by the state.

Compared with traditional buildings, precast buildings have significant carbon emission advantages.

With the vigorous development of precast buildings in China, investors from all walks of life have entered the industry layout.

Erection Anchor One Sided

In 2020, the newly constructed precast buildings in 31 provinces, autonomous regions, municipalities directly under the central government and Xinjiang production and Construction Corps totaled 630 million square meters, an increase of 50% over 2019, accounting for about 20.5% of the newly-built building area, and achieved the work goal of 2020 set in the action plan for precast buildings in the 13th five year plan.

From the perspective of regional distribution, in 2020, the proportion of newly started precast buildings in China’s key promotion areas accounted for 54.6% of the country, and the proportion of actively promoted areas and encouraged areas accounted for 45.4%.

Precast building is the development trend of the construction industry.

From the perspective of regional distribution, there are many precast construction projects in Beijing and Shandong Province, accounting for 15% of the national precast construction projects; Followed by Shanghai, Jiangsu and Zhejiang, with projects accounting for 14%, 13% and 7% respectively; The proportion of precast construction projects in Hubei Province is 8%.

The relevant top-level policy framework of assembly continues to add bricks and tiles, and the policy is gradually maturing.

By 2020, a total of 328 state-level cast construction industrial bases and 908 provincial industrial bases have been established in China.

Nowadays, with the continuous development of the construction industry, precast buildings have been more and more widely used in China.

With the active promotion of precast construction projects all over the country, the scale of China’s precast construction industry continues to expand.

Precast buildings adopt large-scale and intensive production, which can save consumables, reduce energy consumption and reduce construction waste to a certain extent; In the process of building construction, it adopts the way of mechanized installation, which can reduce the pollution such as noise, waste gas and waste water discharge, and reduce the carbon emission in the whole building life cycle.

Among them, the component production capacity and capacity utilization rate were further improved, and the annual assembled decoration area increased by 58.7% compared with 2019.

In 2020, the proportion of newly started precast buildings in key promotion areas such as Beijing Tianjin Hebei, Yangtze River Delta and Pearl River Delta accounted for 54.6% of the country, and the proportion of key promotion areas was further higher than that in 2019..

Driven by policy support, the precast building industry has developed well.

The upstream of the industrial chain of precast construction industry is mainly cement, steel, wood and other raw materials and related precast component production equipment; The middle reaches mainly include architectural design, component production, architectural construction and precast decoration; The downstream of the industrial chain is mainly all kinds of precast buildings and related operation and maintenance.

With the enhancement of policy drive and market endogenous power, the cast construction related industries have developed rapidly.

Among them, the proportion of newly started precast buildings in Shanghai accounted for 91.7%, 40.2% in Beijing, and more than 30% in Tianjin, Jiangsu Province, Zhejiang Province, Hunan Province and Hainan Province.

The proportion of projects in Shanghai, Shandong, Jiangsu and Zhejiang alone has reached 49%.

In the precast construction industry chain, component production and assembly decoration have become new highlights.

An indispensable link in the process of urbanization transformation is the replacement of buildings.

Since July 2020, a number of heavy support policies have been issued for precast buildings.

The 14th five year plan further defines the direction of precast buildings and the related trends of new industrialization, informatization and green.

In 2021, Guizhou, Yunnan, Gansu and other places have issued promotion policies for precast buildings and green buildings.

According to data, in 2020, China’s newly started precast building area was 630 million square meters, an increase of 50.7% year-on-year in 2019; It accounts for 20.5% of the total area of newly started buildings.

According to the data, in October 2021, the number of investment records through the cast construction industry in China was 14, 33 less than that in October 2020.

Click the blue word above and remember to pay attention to us! With the steady growth of China’s economy, China’s urbanization process is accelerating.

It is necessary to improve the blank area of research as soon as possible while promoting the development of precast building, And in view of the problems in the implementation of precast buildings, this paper puts forward promotion strategies to enrich the research system of precast buildings.

China’s research on precast building has made certain achievements and ushered in good development opportunities with the promotion of government policies, but a perfect research theoretical system has not been formed.

Precast components are assembled on the construction site.
