Research On The Ironed Model

The ironed model(tangyang)is architectural model in Qing dynasty playing significant role in architecture project as a 3d design medium.The extant models of yangshilei archives are worthful to study ancient Chinese architectural design.It is helpful for both conservation and historical research to investigate specific model from the perspective of material based on the achievement from Tianjin University group.This study investigated and documented a tomb model in the architectural school of Tsinghua University combining historical literature,scientific observation and experiment together with replicating craft in order to file it comprehensively and find its craft and material.Moreover,the design and the relationship between the model and real structure was explored.The model was believed to be one of two models of Dingdong tomb made in 1873 which was modified and restored according to its present situation,old photos and historical literature.Observation through visible and ultra-violet light provides preliminary result of its craft while X-ray photos unfolded its interior structure.The surface structure was indicated by CSM.The appearance of pigment and fiber was manifested by PLM and its elements were analyzed by XRF,providing evidence of the kind of pigment,paper and adhesion used in this model.Replication supplemented previous research to establish data for conservation.The design of its component,dimension and interior structure was then discussed.The usage of model in construction was analyzed based on this model and other ironed models.Ironing model was a common technique in Qing dynasty that was applied in showing existed structure and new design,conducting and managing construction together with connecting architect,client and worker as a multifunctional design medium.Finally,the study compered the ironed model with earlier architectural models in ancient China and western countries to find the characteristics and value of the ironed model from the perspective of material,craft and function.
