Analysis Of Factors Affecting The Quality Of Prefabricated Building And Study Of Management Countermeasures

Thanks to the implementation of national policies,especially the promotion of urbanization strategy and supply-side reform,the construction industry is facing transformation and upgrading,and the development of prefabricated buildings has reached an unprecedented height.The prefabricated building also has some problems in the process of development,among which the quality problem is a prominent one.Quality problems in prefabricated buildings are usually not caused by a single factor.Therefore,on the premise of identifying these influencing factors,it is of great significance to further clarify the mechanism of the influencing factors for the improvement of quality problems.First,based on the research status of sorting,and summarize the prefabricated building quality management connotation,classification,characteristics,quality management status.Secondly,on the basis of field research and literature analysis,the factors affecting the quality of prefabricated buildings are summarized.On this basis,the list of main factors is obtained by means of questionnaire and factor analysis.Then,using ISM model to clarify the transfer relationship between the main influencing factors and construct a hierarchical structure diagram.The research shows that the government’s participation has a great influence on other factors,which is the deep-seated influence factor,while the component quality problem is the surface influence factor which is greatly influenced by other factors.Finally,based on the research of factor analysis and interpretive structure model,the quality management countermeasures and suggestions are put forward.The study concludes that improving the quality of prefabricated building construction should focus on four points,which are personnel training,quality management system,quality management improvement,and quality technology.First,a talent training mechanism should be established to guarantee the human resources for the development of prefabricated buildings.Secondly,we should improve the related quality management system and do a good job in top-level design.Then,according to the management difficulty of each participant,the quality management improvement strategy is put forward.Finally,in order to solve technical problems,quality technology research and development should be accelerated.
