北京大兴国际机场航站楼立面围护系统设计

DESIGN OF FACADE ENCLOSURE SYSTEM FOR THE TERMINAL BUILDING OF BDIA

从机场航站楼这一特定建筑类型出发,幕墙系统作为常见的表皮形式,我们不断在研究其表现效果与功能特性协调统一。而作为北京大兴国际机场航站楼的立面围护体系不仅是幕墙系统,还包括与之相关的建筑主体结构以及立面外幕墙体现的功能性构件和装饰性构件等。各元素之间需要整体考虑,进行一体化设计。结构方面,外围的支承结构不仅用于支撑屋面,很大部分是承担外幕墙的荷载,与幕墙系统的设计也是息息相关。得益于外围支承结构,外幕墙采用无横梁框架式玻璃幕墙所呈现出很好的效果。同时,除幕墙以外的立面元素需综合考虑,以展开立面的形式直观表达,彼此协调达到最终效果。

Starting from the specific building type of the airport terminal building,the curtain wall system is a common form of skin,and we are constantly studying the coordination and unity of its performance effects and functional characteristics.The facade enclosure system of BDIA is not only a curtain wall system,but also the main structure of the building and the functional and decorative components embodied in the facade exterior curtain wall.All elements need to be considered as an integrated design.In terms of structure,the outer supporting structure is not only used to support the roof,but also bears most of the load of the external curtain wall,which is also closely related to the design of the curtain wall system.Thanks to the peripheral supporting structure,the outer curtain wall adopts a beamless frame glass curtain wall to present a good effect.At the same time,the fa?ade elements other than the curtain wall need to be considered comprehensively and expressed intuitively in the form of an unfolded fa?ade,coordinated with each other to achieve the final effect.
