The Research For Structural Design Of Architecture Roofing System In Extreme Hot And Humid Climate Region

The South China Sea,far from the mainland,has extreme climate conditions very different from that of the Chinese mainland,and presents extreme environment for the coexistence of high temperature,high humidity,strong radiation and strong salt fog.In order to build low energy buildings in this extremely hot and humid climate area,it is necessary to design an enclosure structure suitable for local climate.The existing research on the thermal parameters of the enclosure structure under the extreme hot and wet climate is not clear,which leads to the design of the existing enclosure structure which is difficult to meet the thermal design requirements of the energy saving building in the extreme hot and wet climate zone.Therefore,it is urgent to study the structural design of roof system in extremely hot and humid climates.This paper studies the thermal insulation design theory of building enclosure,and studies the parameters of thermal insulation materials and waterproof materials by analyzing the limitations of the existing standard standards in the construction of the South China Sea.And this paper makes full use of the energy saving roof structure design knowledge,and carries out a large number of thermal calculation on various roof structures,and obtains the thermal parameters of roofs under different roof structure,different insulation materials and different material thickness.This paper systematically classifies the principles of thermal design of building roofs and the types of building energy-saving roofs;The selection of main materials for building roof structures under high temperature,high humidity and strong radiation in the South China Sea is made clear;The matching relationship between the thermal design parameters,the thickness of heat insulation material and the local climate environment is revealed,and a roof structure which meets the existing standard and adapts to the extreme hot and wet climate conditions is constructed;The construction roof structure system for South China Sea Islands is proposed.To explore strategies and methods for building roofing design in extremely hot and humid climates,the research results will provide reference for building roof design in extremely hot and humid climates in China.
