Research On The Construction Of Prefabricated Components BIM Database

The development mode of assembly architecture has changed greatly in recent years,and its change is an important means to promote the development of urbanization in China.The promotion of fabricated buildings can save resources,reduce the pollution caused by the construction,and ensure the quality of construction while effectively improving the work efficiency and the safety of construction personnel.However,traditional assembly design methods still have the problems of extensive traditional construction methods,low design efficiency and low industrial level.Based on the national key research project "building design analysis software and prefabricated database research and development",focuses on the precast BIM database construction method,trying to provide a new idea for the assembly structure design,construction integration finally can realize the design,production and construction.The main research work and achievements of this paper are as follows:Firstly,the concept and characteristics of precast components are reviewed.The concept and design principles of BIM database are analyzed.Combined with the contents of the project,the expected function of BIM database is summarized.The general problem of the BIM model of structural components is studied.Prefabricated variety,usually prefabricated custom factory production,put forward on the basis of prefabricated universal definition,then understand the domestic and foreign existing assembling structure system,summarize the general problem of the origin,characteristics of the general BIM model of prefabricated more targeted.Finally,the BIM model of floor,staircase,beam and column is taken as the research object,and the corresponding general types and key parameters are found out,which provide solid model and internal parameter support for the construction of BIM database.The construction steps of the prefabricated component BIM database are studied.The key technologies such as the classification and coding of prefabricated components,the information depth division of components,the entry of information,and the establishment of prefabricated components are studied in detail,and the general functional design of BIM component library is carried out.Finally,in Shenyang south building project as the background,summarizes the disadvantages of the traditional design method of assembly,and targeted research and application of assembly type structure design method of BIM based on component library,as far as possible play the advantages of BIM component library in the design of the assembly structure.
