Research On Application Of Prefabricated Buildings Based On BIM In New Countryside Construction

New rural construction is an important part of China's socialist construction.With the rapid development of China's economy and the improvement of people's living standard,the traditional rural housing is unable to meet the requirements of the people.The rural residents are constantly renovating,new houses and local governments Also uses different means to carry out the unified planning and construction of new rural housing in order to achieve the purpose of saving land,optimizing resources and improving the living conditions of rural residents.Large-scale market,the more standardized form of construction for the development of assembly-style buildings and provide a very good stage,as a background to explore the combination of BIM and the new rural construction model and the realization of the way for the development of assembly-style buildings Provide help.Based on the BIM technology application standard,the application fineness and evaluation system of BIM model and the characteristics and classification of prefabricated building system,this paper analyzes the characteristics and classification of precast concrete(PC)PC component prefabrication rate,component repetition rate and construction cost.The purpose of BIM technology in the design stage of assembly building,PC component factory production stage,transportation installation stage,operation phase of the specific application content were summarized,pointed out that the BIM technology application In the assembly of buildings can effectively solve the current technical and management problems,is conducive to the promotion of assembly and application.Through the investigation and research,this paper classifies the new rural construction mode in China as three types of urban new countryside,suburban new countryside and relocation and resettlement new rural areas,and discusses the three models with unified planning,centralized construction,building structure,construction High structural repeatability and simple geometrical shape of the component.It is suitable for the early stage of the assembly building to explore and accumulate experience-based applications,while the use of assembly-building can improve the quality of analyzes the construction cost,construction progress and benefit of the traditional cast-in-place model and the assembly model,and the influence of the different pre-processing rate on the cost of the assembled house,and puts forward the measures to reduce the cost.The new rural construction provides a good development environment for the assembled buildings with the advantages of small building volume,simple structure and moderate scale.Through the research of this paper,we hope that the new stage of BIM technology and prefabricated construction will be promoted in our country for the construction industry To the design,production,construction and installation of the latter part of the operation and maintenance,removal and other life cycle construction of accumulated technology and management experience,in order to achieve the transformation and upgrading of China's construction industry for rural residents to live in high-quality,low-cost housing to contribute.
