BIM-based Research On The Construction Technology Of Naxi Traditional Houses In Lijiang

In this paper,the lijiang naxi traditional timber frame construction for research object,from the wooden comb and set up the lijiang naxi traditional timber frame system,the introduction of BIM technology in REVIT auxiliary analysis platform,and the analysis results by physical model to confirm guarantee the accuracy of the software ana lysis of science,in the lijiang naxi traditional timber frame is established in this paper,and then analyzes the lijiang naxi traditional timber frame class differences and the causes of difference between,on the basis of this,according to data collected by the inference the evolution of the relationship between the lijiang naxi traditional timber frame,eventually improve the lijiang naxi traditional timber frame system.System,choose the most representative of traditional timber frame construction is riding a mansion building concrete construction analysis,from the scale modulus,the base of production,material and machining of the timber frame,mortise and tenon joint shape and production and roof tiles of nodes,and so on has carried on the description and analysis,will eventually all the components for the intensification of timber frame model,in this paper shows the more complex and distinctive timber frame 3 d model details and complex component combination node.In addition,according to the research results,the causes of excellent seismic performance of qixia building are systematically analyzed and summarized,and the construction of qixia building,especially the construction of wooden frame,is systematically elaborated.According to the previous research conclusions on the construction of wooden frame of qixia building,the REVIT platform of BIM technology was introduced to build the digital model of wooden frame of qixia building,and the application attempt of BIM technology in the modeling of ancient buildings was made.According to the above research results,REVIT softrware was used to complete the modeling of all wood components,and representative components were selected.The modeling ideas,methods and processes were elaborated in detail in this paper,and the REVIT components finally built in qixialou were recorded into the REVIT model library for the convenience of later generations.In the process of modeling,as a result of the limitation of modeling software can't use the software in the component intelligent linkage between the function,greatly reduces the built model of intelligent parameter adjustment,so the author introduced chateau mammont visual programming software,wrote the visual program solved the problems such as not smart linkage between components,to break the barriers on the REVIT software application in ancient architecture modeling,but also to the chateau marmont visual programming software application provides a new train of thought.In order to ensure the establishment of a more complete intelligent model of the building,a further attempt was made to establish the intelligent maintenance structure of the building.Python Script programming language was used to realize the preparation of the intelligent creation program of the building maintenance structure based on the Python Script node in Dynamo programming software.After the preparation of the program can achieve the intelligent wall and shaft network to create,and fast and accurate.In the process of writing Python Script program,the author steps the first step of REVIT software redevelopment by calling the REVIT Application Programming Interface,realizing the new attempt of software redevelopment by non-professional programmers.It provides some reference for the redevelopment of REVIT software in the future.
