| A number of old grain depots built in China in the last century are in a state of disuse because they are not suitable for the upgrading of modern machinery and equipment and lag behind the new type of grain depots,which brings an opportunity for the transformation and reuse of old grain depots.This topic takes the old grain depots as the research object,on the basis of the investigation and classification of the old grain depots and the full cognition of their architectural forms,discusses the value of the transformation and reuse of the old grain depots.Then,based on the concept of protective transformation design,the paper discusses the design method of transformation and reuse of grain depot buildings,and explores the design practice through the renovation and reuse project of the old grain depot in Gaomiao Township of Sanmenxia.The research abstract is as follows:Firstly,through literature research,grain depots belong to rural industrial buildings,and the concepts and strategies related to the transformation and reuse of industrial buildings heritage and grain depots are sorted out.Based on the research of the representative old grain depot in Henan province,the paper classifies and discusses the state and structure of the present old grain depot in China.On this basis,the paper analyzes the advantages of the transformation and reuse of old grain depots and the value correlation with urban renewal.Secondly,the concept of protective transformation design is clearly put forward,and the connotation of the concept in the three aspects of preservation consciousness,efficient reuse and inheritance of specific cultural context,as well as the design principles of maintenance,suitability and coordination of the old grain depot is expounded.Then combining with the case,the paper discusses the three levels of design techniques of space transformation,style protection and inheritance and place spirit reconstruction.Finally,through the old grain depot renovation project in Gaomiao Township of Sanmenxia,the paper conducts targeted design and operation exploration. |
