架构师提供的文本描述。9月17日至10月12日，艾莉森·布鲁克斯建筑师与美国哈德伍德出口委员会(AHEC)、Arup和伦敦设计节合作，在切尔西艺术学院Rootstein Hopkins游行场地展示了一种跨层郁金香结构，“微笑”。

Text description provided by the architects. Alison Brooks Architects has collaborated with The American Hardwood Export Council (AHEC), Arup and the London Design Festival to present a cross-laminated tulipwood structure, ‘The Smile’ at the Chelsea College of Art Rootstein Hopkins Parade Ground from 17 September until 12 October.

微笑是艺术节的地标项目之一，可供公众居住和探索。这座壮观的弯曲管状木结构有3.5米高，4.5米宽，34米长，实际上是两端弯曲的梁。展示跨层美国郁金香的结构和空间潜力，艾莉森布鲁克斯的概念是有史以来第一个‘超级管’与建筑尺寸的硬木CLT面板。

The Smile is one of the Festival’s Landmark Projects, which can be inhabited and explored by the public. The spectacular, curved, tubular timber structure measures 3.5m high, 4.5m wide and 34m long and is effectively a beam curving up at both ends. Showcasing the structural and spatial potential of cross-laminated American tulipwood, Alison Brooks' concept is the first ever ‘mega-tube’ made with construction-sized panels of hardwood CLT.

关于交叉层合郁金香

ABOUT CROSS LAMINATED TULIPWOOD

交叉层合木材(CLT)是一种工程木材，可用于建造整个建筑物的墙壁和地板。它有一个分层结构，木材纤维在每一个接续层中以直角旋转，在两个方向形成一个强度相等的面板，就像胶合板一样。重量的重量，CLT比混凝土更强，它也可以被加工到难以置信的高公差。这使得它是理想的预制和快速装配，减少建设时间高达30%。CLT通常是由一种名为云杉的软木制成，俗称圣诞树。AHEC和Arup一起开始了一个用快速生长的北美郁金香制成的CLT的实验过程。测试表明，郁金香比云杉强得多，而且外观也很好。

Cross-laminated timber (CLT) is an engineered timber that can be used to make the walls and floors of entire buildings. It has a layered construction with the wood fibres turned at right angles in each successive layer, creating a panel with equal strength in both directions, just like plywood. Weight for weight, CLT is stronger than concrete and it can also be machined to incredibly high tolerances. This makes it ideal for prefabrication and rapid assembly, reducing construction times by up to 30%. CLT is usually made of a softwood called spruce, better known as the Christmas tree. Together with Arup, AHEC has started a process of experimenting with CLT made from fast-grown North American tulipwood. Testing has shown that the tulipwood is considerably stronger than spruce; it also has a superior appearance.

微笑是世界上第一个使用大型硬木CLT面板的项目，事实上，整个结构是由12个巨大的郁金香木面板组成的，每个面板长达14米，宽4.5米。在一个真正的CLT生产厂制造这些面板是重要的一步，展示了如何将这种材料用于商业项目。

The Smile is the first project in the world to use large hardwood CLT panels, in fact the entire structure is made from just 12 huge tulipwood panels, each up to 14m long and 4.5m wide. Fabricating these panels in a real CLT production plant has been an important step forward, showcasing how the material can be used for commercial projects.
