Abstract

While small, the Dinosaur Bridge demonstrates how close collaboration between the design and fabrication team and a rigorous process of modelmaking and prototyping can create a delicate structure that suggests new ways of generating sculptural form. A team of Tonkin Liu (architects), Arup (structural engineering) and Cake Industries (fabrication and installation) were commissioned by the charitable body that looks after the Victorian Dinosaur sculptures in Crystal Palace Park, London, to improve access for maintenance and educational purposes to the heritage island. By drawing on and abstracting references from the natural world, the team developed a scheme for an eight metre swing bridge that creates a complex sculptural geometry from flat laser cut steel sheet. By cutting a “comb” from a 10 mm thick plate, the cantilever struts, deck stiffeners and balustrade posts could all be folded from a single piece. This framework is attached to a triangular and profiled box girder, creating a structure that is visually striking, with sinusoidal forms that act both visually and structurally. This paper describes the collaborative process of developing the design through understanding and incorporating the fabrication process in the design concept, and working at various physical model scales through to full size testing. The bridge is due to be installed in autumn 2020.

摘要

恐龙桥虽然很小，但展示了设计和制造团队之间的密切合作以及严格的模型制作和原型制作过程可以创造出一种精致的结构，从而提出产生雕塑形式的新方法。一个由 Tonkin Liu（建筑师）、Arup（结构工程）和 Cake Industries（制造和安装）组成的团队受慈善机构委托，该机构负责管理伦敦水晶宫公园的维多利亚恐龙雕塑，以改善维护和教育目的到遗产岛。通过借鉴和抽象自然界的参考资料，该团队开发了一个八米摆桥方案，该方案利用平面激光切割钢板创建了一个复杂的雕塑几何体。通过从 10 毫米厚的板上切割“梳子”，悬臂支柱，甲板加强筋和栏杆柱都可以从一个整体折叠。这个框架连接到一个三角形的异形箱梁上，创造了一个视觉上引人注目的结构，正弦形式在视觉和结构上都起作用。本文描述了通过理解和将制造过程纳入设计概念来开发设计的协作过程，以及在各种物理模型比例下进行全尺寸测试的协作过程。该桥将于 2020 年秋季安装。本文描述了通过理解和将制造过程纳入设计概念来开发设计的协作过程，以及在各种物理模型比例下进行全尺寸测试的协作过程。该桥将于 2020 年秋季安装。本文描述了通过理解和将制造过程纳入设计概念来开发设计的协作过程，以及在各种物理模型比例下进行全尺寸测试的协作过程。该桥将于 2020 年秋季安装。
