灯笼形态的比奥比奥剧院／Smiljan Radić

建筑师Smiljan Radić、Eduardo Castillo和Gabriela Medrano为智利康塞普西翁市设计了一座剧院，其内部为网格状的混凝土柱子，外部覆盖着半透明表皮。

比奥比奥剧院（The Teatro Regional del Bíobío）坐落在比奥比奥河河畔，该河流贯穿智利的多座城市。Radić、Castillo和Medrano三位建筑师于2011年赢得了该剧院设计的竞赛，在今年早些时候剧院投入建设。

A translucent concertinaed shell conceals the gridded concrete interior of this theatre designed by architects Smiljan Radić, Eduardo Castillo and Gabriela Medrano for the city of Concepción, Chile.
The Teatro Regional del Bíobío stands on the edge of the Biobío River that runs through the Chilean city. A trio of architects – Radić, Castillo and Medrano – won a competition to design the theatre back in 2011 and it opened earlier this year.

建筑师们采用了一种内部与外部截然不同的设计方式。其灵感来自于波兰戏剧导演Tadeusz Kantor的一段话：“我把它藏起来，封起来，我的包装表达事物的本质。”

半透明的聚四氟乙烯（PTFE）膜覆盖在混凝土框架外，形成双重立面的效果。

The architects developed a design with a contrasting interior and exterior appearance, based on a quote by Polish theatre director Tadeusz Kantor: "My packagings were an attempt to 'portend' the nature of the object. By hiding it, enveloping it."
A skin of semi-transparent polytetrafluoroethylene (PTFE) is laid over a regimented concrete framework to create this duality.

2014年，Radić在伦敦设计的球状蛇形画廊展馆使用了类似的半透明白色玻璃纤维。

覆盖在建筑外侧的条带与大楼层楼一一对应，每一层反射的方向相对，从而产生协调的效果。夜晚，灯光透过表皮向四周漫射，整座建筑好似河畔漂浮的纸灯笼。

Radić employed a similarly translucent skin of white fibreglass for the globular Serpentine Gallery Pavilion he created in London in 2014.
The covering is applied in bands corresponding with the building's six storeys, with each level tilted in opposing direction to the next to create a concertinaed effect. Light shining through the facade at night lends the form the appearance of a paper lantern on the water's edge.

在白天，安装在聚四氟乙烯板之间的玻璃为建筑内部空间带来了良好的采光效果。

一层的玻璃和下面的混凝土框架沿着这座9，650平方米的建筑底部向外展开，形成了环绕在其周围的公共广场的隐蔽入口。

Sections of glazing set into the PTFE help illuminate lobbies and circulation areas during the day.
One band of glazing and the concrete skeleton beneath it splay outwards at the base of the 9,650-square-metre building, creating a sheltered entrance off the public plaza that surrounds it.

内部的两座剧院和棕色镶板包裹的彩排室排布在混凝土框架内的不同高度上，而栅格则位于地面层，形成大门厅。

内部木质座椅呈岩石状，点缀在框架之间的空隙之中。建筑师通过类似脚手架结构来支撑着舞台。

Two theatres and a rehearsal room encased in brown panelling are suspended at different heights within the concrete frame, while the grid is kept open at ground level to create a large foyer.
Faceted timber seats shaped like hewn rocks dot the 3.9-metre gaps in the frame, which the architects compare to the scaffolding structures used to support stage props.

建筑师们在一份声明中说：“在室内，观众可以有序地利用空间网格的每个角落。”

“大厅周围的支架只不过是脚手架而已，就好像舞台后面的幕布和一些支撑构件常常隐藏起来。”

"Inside, the spectator will move/climb a spatial grid that stubbornly appears to measure/occupy each corner," said a statement from the architects.
"All this paraphernalia around the halls [...] is simply a scaffolding, as if it were the backstage part of a scenery, the lower-rank supporting structure that is usually hidden from view."

带有玻璃栏杆的混凝土台阶和一对玻璃电梯与栅格相结合，而框架中的对角线则由一系列灯光所点缀。在其中一个剧院里，条形灯光将网格图案延伸至天花板。

灯笼意向十分为建筑师们所喜爱。2017年，美国Skidmore Owings & Merrill建筑事务在北京的一座网状结构建筑中也运用了灯笼形态。

Flights of concrete steps with glass balustrades and a pair of glazed lifts adhere to the grid, while diagonals in the framework are accentuated by strings of lights. Inside one of the theatres, strip lights continue the gridded pattern onto the ceiling.
The lantern is a popular reference point with architects, and in 2017 American firm Skidmore Owings & Merrill also drew on the form for a faceted tower with a latticed exoskeleton in Beijing.
