3D打印技术及其在超高层建筑应用的可行性分析

3D printing technology and feasibility analysis of its application in super high-rise buildings

收集了国内外31个机构所采用的3D打印设备及工艺,分析了3D打印设备及工艺特点。基于统计分析结果,给出了3D打印在建筑工程中的分阶段应用技术路线,包括打印异形非承重结构、复杂模板及节点、轻质承重结构、异形房屋和异形建(构)筑物。以高层、超高层建筑为研究对象,介绍了爬升式和落地式造楼装备的结构原理,提出了3D打印设备发展的技术方案,即3D打印设备与现有造楼装备集成和开发新型3D打印设备;分析了3D打印技术在超高层建筑工程应用的可行性和挑战。

The equipment and processes of 3 D printing used by 31 institutions at home and abroad were collected, the characteristics of 3 D printing equipment and processes were analyzed. Based on the results of statistics and analysis, the technical route for phased application of 3 D printing in building engineering was given, including printing special-shaped non-load-bearing structures, complex formwork and joints, light-weight load-bearing structures, special-shaped house and buildings or structures. Based on the research objects of high-rise and super high-rise buildings, the structural principles of climbing and floor-standing building machine were introduced. Technical solutions for the development of 3 D printing equipment were proposed, that is, the integration of 3 D printing equipment with existing building machine and the development of new 3 D printing equipment. The feasibility and challenges of the application of construction 3 D printing technology in super high-rise projects were discussed.
