Research On The Establishment And Utilization Of The Wooden Structure Information Model Of Ancient Buildings In Ming And Qing Dynasties

Chinese ancient architecture is an important historical wealth of the country.Compared with western masonry structures,ancient architecture in China is dominated by wooden frames.The destruction of ancient architecture by the natural environment is inevitable,such as natural weathering,acid rain erosion,and sunburn.? Wait,the protection is much higher than the western masonry buildings,and the protection of ancient Chinese buildings is even more difficult.For this reason,most of the existing relatively complete wooden structures are mainly Ming and Qing ancient buildings,which are the historical development of Chinese ancient buildings.The important part of this project is of great appreciation and research value,among which the wooden elements of ancient buildings are the basic objects for research.In order to promote the further development of the research on the protection of ancient buildings and break through the traditional research thinking and methods,this study takes the wooden components of ancient buildings in the Ming and Qing Dynasties as the research object,and uses the equal proportion Douyu model and the ancient architecture of Jingyi Garden in Beijing Xiangshan as examples.Scanning technology is combined with ancient architecture research.The current advanced 3D laser scanning technology is used to obtain relevant data to establish an information model,and model data analysis is performed for wooden components.Finally,the information model obtained from scanning and the relevant conclusions of data analysis are tentatively used.In the information model building part,on the one hand,this study conducts a detailed analysis of the ancient building wooden members.For the local wooden members in the non-working state and the overall wooden members in the working state,the content focus,implementation conditions,and basic requirements of their mapping are respectively Make specific research,on the otherhand,compare the specific characteristics of various modern mapping techniques and target,and after selecting 3D laser scanning technology as the main method of this research,carry out detailed optimization of each specific step of the technology implementation process to find The best operating procedures for the protection of ancient building wood elements.In the analysis of information model,this research is based on the data obtained by 3D laser scanning surveying and mapping.Using the advantages of comprehensiveness and accuracy of the information model in the data,it conducts specific analysis of various results,and analyzes the specific data error of the surveying and mapping results.According to the corresponding error analysis,a better solution for the scanning process is obtained,and the problem points in the results are analyzed with insufficient work and too much attention.In terms of the use of information models,on the one hand,the 3D models in the results and the converted 2D drawings are output and saved,which can be used in subsequent repair projects;on the other hand,the results are carried out in cross-professional collaborative research,and the models are used in ANSYS structural force analysis,BIM ancient building wood components and 3D printing of wood components,and other specific applications.This complete set of detailed and detailed scheme implementation process is obtained,and continuous in-depth research is made on the future use prospects.I hope to contribute new strategies for the protection of ancient national buildings,and make ancient buildings protection projects and modern The development of architecture goes hand in hand.
