北京地铁西二旗站|Xi’erqi Station of Beijing Subway | Li Xinggang

西二旗站是北京地铁昌平线的南起点站,是与城铁13号线的换乘站。车站形式为半地下一层、地上二层,四柱三跨框架式高架车站。其中的昌平线部分为高架侧式站台(二层),城铁13号线部分为地面侧式站台(一层),站厅位于地面一层。根据侧式站台的特征,车站采用了双四边形组合建筑断面形式,并以PTFE膜结构作为屋面和立面维护材料和结构,实现了内部基本无柱的长向大空间。

Xi’erqi Station is the southern terminal of Subway Changping Line in Beijing and its transfer station to Subway Line 13. The station is an elevated frame-type building consisting of a semi-underground storey and two above-ground stories supported by four colonnades that create three spans. The Champping Line part consists of an elevated side platform on the second storey and the Line 13 is part of a ground side
platform on the ground storey. Based on the characteristics of side platforms, the cross-section of the buildings consists of two quadrangles
combined with each other. PTFE membrane functions as the material and structure that enclose the roof and facade to provide a long-large
space in which few columns are present.

适应地铁交通需求的双四边形组合筒状空间被直接外现为建筑的造型,并采用了折纸状的结构和形式,实现了模数化、标准化、预制化的设计与建造,简洁、流畅而富于韵律感,真实而充分地体现了张拉膜材料和结构的特征,建筑形式也与结构、排水等要求相适应。车站的出入口大厅、雨篷等元素采用了一体化的建筑语汇。

Accommodating subway transportation, the tubular space formed by the combination of the two quadrangles is directly exposed to show the
shape of the architecture. The structure and form, like something folded with paper, enable modular, standardized, prefabricated construction.

The concise, fluent, and rhythmic architecture indeed expresses the characteristics of tensile membrane. The architectural form also meets the
structure and drainage requirements.

由于PTFE膜材料的半透光特性,白天的车站内可以透射进柔和而充分的自然光线,无须人工照明;到了夜晚,车站内的灯光透射出去,使得车站就像两条发光的纸灯笼,乘坐地铁回家的人远远就可以看到。地铁西二旗站以其不动声色的建筑姿态与人们日常生活的密切关联并成为重要的“城市标志物”。

Because of the translucence of the PTFE membrane, soft and sufficient natural light can be transmitted into the station and no artificial lighting 
is necessary in daytime. At night, the lamp light transmitting out of the building makes the station like two bands of lighting paper lanterns that 
can be seen from far away by subway commuters going home. With its quiet architectural pose but close relationship with our daily life, the 
station becomes an important “city landmark”.
