Cost And Benefit Study Of Prefabricated Cavity EPS Module In Rural Housing Construction

Along with the advancement of new type of urbanization,urban and rural development of the growing phenomenon of imbalance,based on the urban and rural dual structure of Chinese social existence main contradiction,xi jinping,general secretary of the country revitalization strategy become the comprehensive construction well-off society,harmonious regional and urban and rural balanced development of the important guiding ideology,in the realization of "two" one hundred target of struggle in the process,The implementation of the rural revitalization strategy is of far-reaching historical significance.The new round of territorial space planning driven by this strategy also provides an opportunity for the comprehensive improvement of rural living environment and the renewal of old housing.With the development of rural economy,the original rural housing has been unable to meet the needs of people’s production and life.The implementation of rural revitalization strategy has put forward higher requirements on the quantity and quality of rural housing construction.Rural housing construction needs a new structural system,which requires short construction period,high quality,personalized,energy saving and other characteristics.Based on this background,this paper analyzes and discusses the research status of prefabricated buildings at home and abroad on the basis of searching a large number of literature materials,and summarizes the advantages of prefabricated buildings compared with traditional brick-concrete structures.However,the promotion and development of prefabricated buildings in rural areas meet bottlenecks due to the impact of cost factors.In this paper,the prefabricated construction technology is analyzed and compared,seek to determine the cost is relatively low,to adapt to the characteristics of village residence assembled cavity EPS module construction technology,and introduces its technical characteristics,using the theory of value engineering to the involved such as masonry structure,reinforced concrete structure building model conducted a scheme comparison,the calculated results are detailed analysis,Finally,according to the incremental cost and benefit theory,the cost and benefit of the assembly cavity EPS module construction technology are comprehensively and systematically quantified,and the conclusion is drawn that it is suitable for rural housing construction,and the thinking and prospect are put forward.The research of new materials and new technology research and application and prefabricated construction technology has certain reference value for the construction of rural housing.
