The Design Research Of Building’s Exyernal Space Environment Of Urban Plane Intersection

The intersections of urban road are divided into many types,and the plane intersection is the most common type.As an important element of the road,intersection play role in the urban space node.The external space environment of intersection ’s building become the external manifestation of sensing nodes,and the architectural form as the main elements of urban image formation is of great importance.They are "anchor point" of city image,people through them to understanding city,learn more about the city;The street on both sides of the intersection building space form tend to be different,to the stand or fall of the external space environment of construction that intersection,relates to whether the street space can naturally transformation,so they are the "breaking point" of street space;In addition,because of the intersection ’s position is special,the transportation is convenient,often gathered a large number of people and traffic,and the people to stay here or communication,and they are also "focal point" of city life.In actual design,however,often only consider the requirements of the specification,but for a lot of restricting factors associated with actual life and demand form.The purpose of this article is based on the actual demand is summarized on the restriction of city grade intersect ion architecture exterior space environment factors,and put forward the corresponding design methods and optimization strategy,hope to be helpful to the practical design.This article embarks from the project background,divided into the following severa l most focus on: the first part,the concept of the subject related definition,at the same time to review and summarize the research status at home and abroad were reviewed.According to time sequence,the road intersection building exterior space environment of the formation,evolution and reform to make a review,trying to find some intersection in history in the study of building external space environment design of the law;The second part,which is based on a large number of actual cases,sums up the factors of the construction’s external space environment of the urban plane intersection,mainly including: the factors of construction’s plane corner space of intersection,the factors of buildings’ stand outside of intersection and the factor of the group of architectural space combination of intersection.They both bring design challenges and design innovation opportunity;The third part,through the analysis of the above factors,respectively from the integrity design of the building plane Angle of intersection,the uniqueness design of construction’s Angle of modelling of intersection,the directivity design of construction’s external space environment of intersection and the correlation design of group building space combination of intersection;The fourth part,summarize the content of the above,summed up three properties of the construction’s external space environment of urban plane intersection: identification,directivity,and integrity.
