Research On Container Building Design Strategy Based On Thermal Performance

With the increase in the volume of international trade,the application of shipping containers has been increasing,and the number of shipping containers that have reached the transportation years has increased year by year.The application of shipping containers to the construction sector not only achieves the purpose of resource recycling,but also has the unique use value of the container building,which has the advantages of rapid construction,modular application and movable building.However,the global promotion of container building is subject to various restrictions,and poor thermal performance is one of the main limitations.Container building has poor insulation effect in winter,and thermal bridge phenomenon brings internal condensation;The container building is stuffy in the summer building,and the ventilation is not smooth,which makes the occupants less comfortable;the narrow box makes the interior lighting poor,the bacteria are easy to breed,and brings health risks to the occupants.A series of physical and environmental problems in the building make the container building not acceptable to most occupants.Based on the thermal performance of container building,this paper provides an architectural design strategy for the envelope structural design of single-box container building and the combination design of multi-box container building,in order to obtain better insulation effect of the enclosure structure,better wind environment and light environment.The full text is divided into five chapters.The first chapter introduces the research status,research content and objectives,research methods and technical routes.The second chapter summarizes the author's investigation of container building,and concludes the construction system of container building.The third chapter studies the thermal bridge problem of the container building keel insulation system.Through the simulation analysis of ANSYS software,the five aspects are studied: the influence of keel size(the keel flange width,the keel height,the keel thickness,the keel spacing)on thermal bridge of container building envelope structure;the influence of keel position on thermal bridge of envelope structure;the thermal bridge optimization of enclosure structure of keel insulation system;the influence of new keel on the thermal bridge of the envelope structure;the comparison of thermal bridge effect of different insulation systems in container buildings.And give design suggestions based on the simulation results.The fourth chapter studies the multi-box combination design of container building.Firstly,it summarizes the multi-box container building cases at domestic and foreign in chronological order,and classifies the multi-box container building into unit type,horizontal superposition type,vertical superposition and enclosed type.For each type of typical actual case,retrofit design based on thermal performance is carried out.And compare wind environment and light environment of container building through simulation of Fluent software and Ecotect software.Finally,the design strategy of multi-box container building based on thermal performance is summarized.The fifth chapter summarizes the research results of the full text and looks forward to the future of container building development.
