191), our company collected and summarized the statistics of the development of precast buildings submitted by various localities, The national development of precast buildings in 2020 is hereby notified as follows: 01 – overall development.
All localities deeply implement the spirit of the central urban work conference and the guiding opinions of the general office of the State Council on vigorously developing precast buildings (GBF [2016] No.
71), adhere to the basic principles of market leading and government promoting, and actively formulate policies and measures, Gradually improve the technical standard system and effectively promote the rapid development of precast buildings.
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 m2, an increase of 50% over 2019, accounting for about 20.5% of the newly-built building area, and completed the work goal of reaching more than 15% by 2020 set in the action plan for precast buildings in the 13th five year plan.
02 – regional development in 2020, the proportion of newly started precast buildings in key areas such as Beijing, Tianjin, Hebei, Yangtze River Delta and Pearl River Delta accounted for 54.6% of the country, and the proportion of actively promoted and encouraged areas accounted for 45.4%.
The proportion of key areas was further higher than that in 2019.
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.
03 – development of different structural types from the perspective of structural form, the newly started precast concrete structure building is 430 million m2, an increase of 59.3% over 2019, accounting for 68.3% of the newly started precast buildings; Precast steel structure buildings are 190 million m2, an increase of 46% over 2019, accounting for 30.2% of newly started precast buildings.
Among them, the newly started cast steel structure residence is 12.06 million m2, an increase of 33% over 2019.
The novel coronavirus pneumonia module has been widely promoted and played an important role in the prevention and control of the new crown pneumonia.
04 – development of industrial chain with the enhancement of policy drive and market endogenous power, precast construction related industries have developed rapidly.
By 2020, a total of 328 National cast construction industrial bases and 908 provincial industrial bases have been established in China.
In the precast construction industry chain, component production and assembly decoration have become new highlights.
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.
At present, in view of the prominent problems that the low degree of standardization generally reflected in various places restricts the development of precast buildings, our company is organizing the preparation of standard for design and selection of precast houses, guide for the dimensions of main components of precast concrete structure houses and guide for the dimensions of main components of residential precast decoration, Combined with the size guide for main components of steel structure residence issued in 2020, build a “1 + 3” standardized design and production system, guide production enterprises, design units and construction units to coordinate and unify the common sizes of components and parts, give play to the leading role of standardization, improve the design, production and construction efficiency of precast buildings, and further promote the coordinated development of the whole production chain.
At the same time, take the precast building as the carrier to jointly promote the industrialization of intelligent construction and new buildings, and promote the transformation, upgrading and high-quality development of the construction industry.
Praise + watch for knowledge together..
