‘微笑’ was a Landmark Project for the 2016 伦敦设计节; a public pavilion in the Chelsea College of Art (UAL) Parade ground that showcased the structural and spatial potential of cross–laminated hardwood using American tulipwood.
这个非凡的结构, designed by Alison Brooks彩票365官方网站事务所 with engineering by 奥雅纳, 跨越彩票365官方网站, 雕塑, 公共艺术. It could be described as an unidentified flying object: a 34m long, 3m high upside down arc poised on the urban horizon. 它是双悬臂的, four sided tube that curved upward to its two open ends, allowing light to wash across its interior 表面s like water across a spillway. 在离地面3米的地方盘旋, its two ends acted as viewing platforms taking in the sky and neighbouring Edwardian buildings. Entering 微笑 through an opening where the curved form meets the ground, 来访者可以走(或跑)!) from end to end of the 34-metre-long tube discovering a dynamically curved space that gradually rises toward light. A segment of a 100m diameter circle, the Smile created an immersive sensory environment integrating structure, 表面, 空间与光线.
微笑 was prefabricated as 12 industrial-sized tulipwood 解释水平理论 panels manufactured by German 解释水平理论 pioneers, 德国z
奥雅纳 applied their latest timber research to devise a structural connection system of 4000 screws over a foot long that can be installed with an ordinary rechargeable screwdriver. At the tube’s mid-span four 1m long steel plates connected the main structural panels at high level, 也用螺丝. A condition of the pavilion taking its place in the Chelsea Parade Ground was that no foundations were possible – the structure had to be self-supporting. The solution was to connect the structure to a 1m deep glulam timber cradle filled with 20 tonnes of steel counterweights. Inches below the cradle are the remains of the 19th-century Millbank prison, once a transit station for convicts before they were deported to Australia.
对于AHEC, 微笑 is one of the most important developments in a decade of research into structural timber innovation with structural engineers, 奥雅纳. For Alison Brooks彩票365官方网站事务所 the installation was an opportunity to free architecture from the conventions of permanent building, to celebrate the sensory qualities of wood, and the chance to stretch a fully renewable, zero-carbon structural material to its limit.
微笑 consisted of around 70 cubic meters of tulipwood and 25 cubic meters of spruce, altogether stores 70 tonnes CO2 eq. Just takes less than five minutes for tulipwood required to be replaced in forest.
