| summary |
Shotcrete 3D concrete printing (SC3DCP) technology offers vast potential for digital fabrication and structural engineering. However, it faces limitations with complex geometries involving non-developable surfaces. To address these technical challenges from a computational perspective, this research introduces an adjustable formwork system based on a discrete interlocking mechanism. The proposed model consists of an octagonal, porous unit inspired by chainmail. By utilizing the unique chainmail pattern and interlocking parts, the proposed form ensures: (1) a wide range of flexibility at each node that can be applied to various types of curved surfaces; (2) can be reused overtime by adjusting each interlocking part; (3) print-in-place capability without external supports, reducing assembly complexity compared to traditional engineered formwork systems. Overall, the research aims to reduce geometric constraints in the construction domain through a novel, practical method. |
