Research On Spatial Information Representation Of Building Structural Components

With the development of the new smart city,all walks of life in the city are building around the "smart industry".As a basic,leading and pillar industry,the development of intelligent building is a new direction for the future development of the construction industry.As a new supporting technology of smart city,it is of great significance to study building informatization and data technology in promoting the development of smart buildings.Intelligent building will solve the problem of information transmission and sharing through a variety of information technology means,among which the application of geographic information(GIS)and building information modeling(BIM)integration technology in architectural engineering is an important development direction of intelligent building development at the present stage.The introduction of geographic information into architectural engineering can enhance the accuracy of spatial location information of buildings and provide reliable and accurate technology for tracking and positioning of building components.In the process of transition and deepening of classical GIS from urban macro information to micro information,massive high-density BIM data are needed as support.In the process of integration of the two,how can the whole life cycle of building components be traced in urban space? Therefore,it is necessary to study how to use big data language to express the initial spatial coordinates and terminal spatial coordinates of building components from production to installation completion.In order to solve the problem of locating and querying building components in space,this paper proposes a method of locating and describing building structural components in space,and defines a spatial information for each building structural component,so as to solve the problem of tracking and locating building structural components and information sharing and transmission.Based on the development needs of building informatization and data,this article first summarizes and studies the classification and characteristic information of building basic structural components in combination with relevant domestic and foreign codes and standards.The requirements are sorted out,and the relevant attributes of the building structure components are clarified through the study of the characteristic information of the building structure components,which provides a basic guarantee for the compilation of the space coordinates of the building structure components.Based on the analysis of the characteristic information of building structural components,combined with national standards and engineering practice requirements,the spatial coordinates of building structural components with certain rules are constructed.The spatial coordinates of building structural components include the type information,location information,geometric information,material information and other related information of the building structural components.The type information is based on the naming of the building construction drawings and incorporates the cross-sectional shape information of the building components.The type information can distinguish and identify building structural components more intuitively and vividly,facilitating the accurate and rapid transmission of information during construction.The three-dimensional coordinate information in the geographic information is added to the spatial position information in the spatial coordinates of the building structural components,which is convenient for the accurate tracking and positioning of the building components in the construction project.The geometric information in the spatial coordinates of building structural components uses the language of data to describe the three-dimensional geometric shapes of the components.The material information in the building components can accurately reflect the materials used in the building components and the carrying capacity information.Then use research documents,national standards and specifications,and examples to prove the rationality and feasibility of building structural component spatial coordinates.Then,BIM-RFID technology is introduced and studied,and BIM-RFID technology is used as a method of spatial information circulation,transmission and information sharing of building structural components.In building structures,design,processing,transportation,installation and operation in each stage,using BIM technology in the building engineering construction to build information and model,and set up information sharing platform,the building structure component spatial information expression information and corresponding construction model to add,each component has the only space coordinates.Finally,the RFID technology is used to carry out the embedded,information storage and identification of the tag chip of the building components,and the identified spatial coordinate information of the building components is uploaded to the BIM platform,so as to realize the purpose of identification,tracking,positioning and information sharing of the building components.Based on the building structures as the research object,database and data identification technology is adopted to establish the tracking and positioning technology can realize building structures,through the integration of architectural engineering components in different stages of the space information to realize the collaborative sharing of information,building components for building engineering information,digital management of effective management measures are put forward and the feasibility of the method.
