| As a part of the building envelope,the exterior wall of the building not only shows the structure and form of the material,but also reflects the social and cultural environment.Exterior walls provide basic functions such as thermal insulation,sun-shading and rain-shielding,ventilation and sound insulation for the building,as well as basic aesthetic comfort.Traditional single-layer walls are difficult to meet the increasing insulation requirements of modern buildings.The gradually developed double-layer cavity wall solves the insulation problem,and brings a series of problems such as cavity drainage and ventilation,so how to solve the problem of wall drainage,ventilation and durability?The exterior wall of the rain curtain system is designed based on these problems and the wall is constantly updated with higher efficiency.This can be used as a guide and reference for the application of architectural design and practical engineering in China.Therefore,it is of practical significance for the author to explore it.The external wall design of dry-hanging rainscreen system is independent from the main structure of the building.It is firstly constructed from the perspective of performance requirements and aesthetic factors should be considered.It is not only the decoration of building materials and color texture,but also the form expression of construction materials.Therefore,the topic is the structure and expression of dry-hanging rain curtain system.Based on the construction of dry-hanging rainscreen system,this paper explores the expression of dry-hanging rainscreen system wall.The introduction part introduces the background and content frame of the thesis.The second chapter starts from the historical development of dry-hanging rain curtain system,and summarizes the concept definition,principle analysis,basic components,and application status at home and abroad,as well as the comparison of fully sealed and semi-sealed systems at the present stage in China.The third and fourth chapters are the core content of this paper.This paper expounds the construction principle and design expression of various parts of the dry-hanging rainscreen system.It mainly analyzes the construction measures of the wall body,the top of the wall,the bottom of the wall and the entrance of doors and windows,the corner of the wall from the perspective of the problem of waterproof weather resistance.At the same time,it positioning the final design expression with the combination of materials and cases.In the fifth chapter,the construction points and installation steps of each part of dry-hanging rainscreen system are presented to provide more complete information.The conclusion summarizes the whole paper and points out the shortcomings of the research.The whole thesis contains about 22 000 words,140pictures and charts. |
