| As the development of urbanization in recent decades,a large number of rapid construction will inevitably lead to the lack of thinking about the details of building structure.Under the impact of the natural environment,such as the wind,sun and rain,the weatherability of the building envelopes gradually appears today.Based on the investigation of poor weatherability of existing buildings,combined with the positive cases at home and abroad,and guided by weatherability itself,this project summarizes,arranges and designs to form the weatherability design atlas.This atlas is intended to provide architects with reference,extend the life of buildings,and improve the quality of buildings.This paper is two parts of the atlas,wall top and roof design,which author participate in under the leadership of the research group.This paper is divided into five chapters.The first chapter is the introduction,including the basic information.The second chapter is the overview.Firstly,it introduces the concept of weatherability,and then defines the main scope of building envelopes.Finally,it introduces the application status of weatherability structure design at home and abroad.The third chapter is the wall top design,which is divided into five sections: parapet,coping,extended eaves,gutter,catch basin and downpipe.Among them,the research focuses on metal coping,double-layer extended eaves and hidden gutter.Because of its large material freedom,the metal coping fully reflects the relationship between design expression and structural details.The double-layer extended eaves can be made of lightweight materials for overhanging,forming a unique visual effect.In terms of hidden gutter,according to different wall and roof materials,four kinds of hidden gutter design are completed,which results in simple modern shapes of slope roof buildings.The fourth chapter is the roof design,which is divided into three sections: roof,ridge and tile.Among them,the antiskid measures of the planting roof and the protection against the wind of metal roof are mainly studied.These two chapters are the main chapters of this paper.Through drawing,modeling and rendering,structural details and facade expression are finished one by one.It clarifies the relationship between weatherability construction and design expression,that is,the design of weatherability construction can actively participate in facade expression,and special expression needs the guarantee of weatherability construction.The fifth chapter is conclusion,which summarizes the content of the paper,analyzes the existing shortcomings,and proposes new prospects.The whole thesis contains about 21 000 words,275 pictures and charts. |
