Comparative Analysis Of Prefabricated Building Structures And BIM Applications

An assembly building is a building used in factory assembly,connection,and part of a prefabricated assembly.Compared with traditional architecture,prefabricated buildings to save energy and resources,the construction process more environmental protection,increase the technological content of architectural characteristics of conform to the trend of modern housing industry developing fast,although our country has carried out the study of prefabricated building altogether,but smaller prefabricated construction in our country compared with foreign developed countries,has the very big development space and potential,so the prefabricated construction is the construction of the future development direction,is in the national development strategy of the important measures in the future.On the basis of fully investigating the support of the national and provincial policies on the assembly type of residential buildings,this paper explores the practical significance and far-reaching impact of the assembly development.Through to the PC system and steel structure technology a detailed comparative analysis of the steel structure system technology advantages and characteristic analysis,show the operability of prefabricated steel structure and maturity,and taking a prefabricated steel structure residential building as an example,elaborated the modelling of prefabricated steel structure building advantage,shows the development space of the prefabricated construction is different from the traditional construction mode.After that,this paper applies BIM technology to the assembly building to carry out the theoretical demonstration.,through a series of case analysis,application in BIM application in prefabricated construction changed the previous project cooperation pattern,construction units can early intervention programs,earlier to get design model,thus more reasonable classification module,purchasing materials,set aside enough time for excellent features such as factory processing.Finally we can see prefabricated construction plays a decisive role in the construction development of the future,with the implement of assembling the construction and the rapid popularization of BIM data related to technology,prefabricated is likely to become the dominant direction of architecture development,it has more sexually,has a huge space for research.
