Research On The Design For Constant-holistically Shadowed Space Of City Leisure Plaza In Hot-summer Area

The hot summer in the hot summer area has a long duration,which greatly restricts the applicability and utilization efficiency of light and heat in the summer day in the city leisure square.It can use the surrounding buildings,structures,and plants more actively,fully,and effectively.At the planning and design stage,targeted design processing in layout,mass,spatial relationship,and transparency has begun to create a kind of Constant-holistically shadowed space(CHSS)that adapts to the scale of time and space to meet the characteristics of the size and time requirements of various leisure activities.Improve its light and thermal comfort and utilization efficiency in summer.Through literature research,survey analysis,and summary,this article clarifies the activity characteristics,shadow space requirements,and existing problems of people using different types of urban leisure squares in summer hot areas,and proposes a combination of the types of urban leisure squares and their spatial and temporal characteristics.To build a CHSS.Based on the simulation of related shadow simulation software,the spatial-temporal correlation mechanism between the influence factors of Constant-holistical shadow(CHS)composition and the CHSS is explored,and the goal of constructing the CHSS of the urban leisure square is established.Approaches and design methods.The main knowledge and research conclusions obtained in this paper are as follows:1.Through the investigation and analysis of the urban leisure square space in the hot summer area,it is found that users' demand for shadow space shows the characteristics of time-space scale difference;different types of urban leisure square show different use demand characteristics,including the age distribution of users,types of leisure activities,activity time,activity area,activity scope;shadow space of urban leisure Square There are some problems such as insufficient shadow time,insufficient space and poor quality.2.Through the simulation analysis of related shadow software,it is found that there is not much difference in the ability to form Constant-holistically shadowed between the three-sided enclosed square and the two-day enclosed square.Constant-holistically shadowed mostly exists on the west and east of the square The side,south and north sides of the Constant-holistically shadowed generally show a long and narrow spatial form,and the usability is not high.The two-sided enclosed plaza places the buildings on the east-west sides of the plaza to form a Constant-holistically shadowed.The three-sided enclosed plaza places the buildings on the east-south-west sides of the plaza and can be formed throughout the day.Constant-holistically shadowed for two hours.3.Through the study of the structure of the structure,it is found that the vertical negative line of the north and south of the building has a great influence on the Constant-holistical shadow.Increasing the length of the vertical negative line of the north and south is an effective means to obtain a large area of Constant-holistical shadow;The later period of the afternoon,the easier it is to obtain Constant-holistical shadow,and the effect of structure sketches to obtain Constant-holistical shadow at noon is the best;structures with straight lines in the shade are easier to get larger than structures with curved lines in the shade The area of Constant-holistically shadowed space.4.According to the characteristics of leisure time and space requirements and the mechanism of the composition of the composition,it is proposed to build a Constant-holistically shadowed space that suits the needs of citizens' activities,a multi-activity time and space composite Constant-holistically shadowed space,and build a high-quality The three construction goals of the Constant-holistically shadowed space are to build three buildings by rationally planning the construction of the buildings around the square,by constructing the buildings and plants inside the square,and by supplementing the shrinkable structures.5.The design of Constant-holistically shadowed space can be gradually realized through planning,design,landscape design,and construction drawing design stages to meet the space needs of people of all sizes,time periods,locations,and duration.The planning and design stage includes the layout design of the surrounding buildings of the square,the pedestrian traffic design of the urban leisure square and the district design of the square;the landscape design stage includes the plant design,the structure configuration design and the structure adaptive design;the construction drawing stage includes the building material selection,Selection of plant species and materials for floor paving.
