: China is in the transition stage from low-income countries to middle-income countries, urbanization construction efforts continue to increase. According to statistics, China's urban housing construction volume of more than 1.2 billion square meters per year, most of them reinforced concrete high-rise buildings, the general use of traditional watering methods for construction. This kind of construction method extensive, energy consumption, low production efficiency, low technical content, high dependence on labor force, uncontrollable cost, lack of effective integration and integration of industrial chain, low scale and intensive degree, building performance and quality can not be guaranteed, because of site construction errors lead to frequent housing quality problems, and cause great damage and waste to the environment and resources.
After entering the 21st century, with the rapid development of China's urbanization and urban modernization process, the contradiction between energy and resource shortage is becoming more and more prominent, ecological construction and environmental protection situation is becoming more and more serious, the original construction industry based on the relatively low labor prices in China, with the disappearance of the population dividend, labor costs continue to rise, construction costs continue to rise, traditional construction methods in terms of building quality, cost and speed increasingly unable to meet the needs of modern social development, and gradually become a bottleneck restricting the further development of China's construction industry. Therefore, it is required that the construction industry must carry out industrialization upgrading, gradually change from the traditional extensive construction to intensive and fine industrial production, reduce the number of labor demand, improve the working environment, reduce the demand for manual labor.
with the development of science and industrial technology, a new type of building model, construction industrialization, came into being. Industrial construction, including the main body of most components and components are produced in the factory, distribution, production follow standardization, industrialization, module coordination, module integration, technology optimization as the basis for large-scale factory assembly line production, large-scale equipment into mass manufacturing as a means of industrialization, mechanized operation and assembly construction as the mode of operation, the traditional construction site into a construction plant "assembly workshop", the formation of good efficiency, good quality, materials, less pollution of the construction industry production mode. Factory construction of green low-carbon buildings can achieve the implementation of the project three major controllable: quality control, cost control and schedule control.
the current use of concrete prefabribriited components in the whole building is far lower than the level of developed countries, the development space is huge. On the one hand, the growth of fixed asset investment in China drives the growth of the construction industry, the space of concrete prefabribriited components industry as a construction sub-industry increases, on the other hand, with the implementation of the strategy of national residential industrialization and building standardization, concrete prefabribriited components with its excellent characteristics will quickly replace the market share of traditional concrete building materials, and further enhance the space of concrete prefabrictory components industry.
2009-2014, China's urban population increased from 621.86 million to 731.11 million, and the urbanization rate increased from 46.6% to 52.57%, according to statistics from the National Bureau of Statistics. It is predicted that by 2030, China's urbanization rate will reach about 65%. From the scale of urbanization in China, whether it is the annual net increase or the total urban population, has long been in the world's first. With the continuous progress of urbanization, housing demand will continue to exist, China's real estate and housing construction investment will continue to grow, and assembly-type construction industry will usher in explosive growth.
