Research On The Integration Of Design And Construction Of Building Envelope System Of The T2 Terminal Of Changchun Longjia International Airport

Now China is in the rapid development period of airport terminal construction,and the potential of airport construction is huge.In addition to its traffic role,airports often shoulder the responsibility of representing a city’s image and embodying regional cultural connotation.In the construction of airport terminals,there are inevitably various problems,but there is a lack of systematic research and technical integration in the construction of airport terminals at home and abroad.At present,most of the research on the construction technology of building envelope system at home and abroad is focused on the single construction technology of roof or curtain wall,and there is no research on the integrated design and construction of roof and curtain wall as an integral envelope.In this paper,the design and construction of the envelope structure of airport terminal are studied,which provides reference for similar building design.Standed on the perspective of the general contractor,with the idea of integration of design and construction,from the two directions of integrated design and integrated construction,taking the building envelope as the research object,combined with Changchun Longjia airport T2 terminal,the integrated design and construction of the terminal buildings with curtain wall and roof as the main enclosure structure are studied and analyzed in detail.In theory,the integrated design concept is applied.It is proposed that the design of enclosure system should be integrated with three directions of building space,building structure and material expression,so as to achieve the perfect final building effect.In the aspect of design,the integrated design is explored.Taking modularization as the starting point,BIM as the tool and T2 terminal main hall as the analysis object,the logical sequence and modular relationship of curtain wall,roof and ceiling design are studied.In the aspect of construction,the integrated construction technology is studied.With the management mode of integration of design and construction and the means of deepening design,the integrated construction is realized through simulation calculation and experimental research.
