Abstract

UNLABELLED

This paper discusses the design, fabrication, and assembly of the 'Eggshell Pavilion', a reinforced concrete structure fabricated using 3D printed thin shell formwork. Formworks for columns and slabs were printed from recycled plastic using a pellet extruder mounted to a robotic arm. The formworks were cast and demoulded, and the finished elements were assembled into a pavilion, showcasing the architectural potential of 3D printed formwork. The Eggshell Pavilion was designed and fabricated within the scope of a design studio at ETH Zurich. The structure was designed using a fully parametric design workflow that allowed for incorporating changes into the design until the fabrication. The pavilion consists of four columns and floor slabs. Each column and floor slab is reinforced with conventional reinforcing bars. Two different methods are used for casting the columns and floor slabs. The columns are cast using 'Digital casting systems', a method for the digitally controlled casting of fast-hardening concrete. Digital casting reduces the hydrostatic pressure exerted on the formwork to a minimum, thereby enabling the casting of tall structures with thin formwork. The floor slabs are cast with a commercially available concrete mix, as the pressure exerted on the formwork walls is lower than for the columns. In this research, 3D printed formwork is combined with traditional reinforcing, casting, and assembly methods, bringing the technology closer to an industrial application.

摘要

未标注

本文讨论了“蛋壳亭”的设计、制造和组装，这是一个使用3D打印薄壳模板制造的钢筋混凝土结构。柱和板的模板是使用安装在机械臂上的颗粒挤出机从回收塑料中打印出来的。模板经过浇筑和脱模，最终的构件被组装成一个亭子，展示了3D打印模板的建筑潜力。“蛋壳亭”是在苏黎世联邦理工学院设计工作室的范围内设计和制造的。该结构采用全参数化设计工作流程进行设计，允许在制造前对设计进行修改。亭子由四根柱子和楼板组成。每根柱子和楼板都用传统的钢筋进行加固。柱子和楼板的浇筑采用了两种不同的方法。柱子采用“数字浇筑系统”进行浇筑，这是一种用于快速硬化混凝土数字控制浇筑的方法。数字浇筑将作用在模板上的静水压力降至最低，从而能够使用薄模板浇筑高层建筑。楼板采用市售混凝土混合料浇筑，因为作用在模板壁上的压力低于柱子。在本研究中，3D打印模板与传统的加固、浇筑和组装方法相结合，使该技术更接近工业应用。
