Abstract

Modular construction offers economic and environmental advantages over conventional construction technologies. Although several researchers have introduced various modular construction systems, the methods for creating channel structures within block modules and injecting epoxy resin to connect blocks efficiently have not been fully explored. This study proposes a new assembly channel system for modular construction using 3D printing. Four different channel types are fabricated using 3D printing, and epoxy resin is injected for block connections. The relationships between channel geometries and structural resistance are thoroughly analyzed with the uniaxial tensile and three-point bending tests. Both experiments are also numerically simulated using the finite element method to validate the modeling methodology for assembly channel systems. The validated methodology is useful for evaluating assembly channel systems and enhancing the design of such systems. Overall, this study can foster the practical application of modularization across various industrial fields.
采用 3D 打印通道系统的新型先进积木组装方法
与传统建筑技术相比,模块化建筑具有经济和环保优势。虽然一些研究人员已经推出了各种模块化建筑系统,但在砌块模块内创建通道结构和注入环氧树脂以有效连接砌块的方法尚未得到充分探索。本研究提出了一种利用三维打印技术建造模块化建筑的新型装配通道系统。利用三维打印技术制作了四种不同类型的通道,并注入环氧树脂用于砌块连接。通过单轴拉伸和三点弯曲试验,深入分析了通道几何形状与结构抗性之间的关系。此外,还使用有限元法对这两项试验进行了数值模拟,以验证装配槽系统的建模方法。经过验证的方法有助于评估装配通道系统和改进此类系统的设计。总之,这项研究可以促进模块化在各个工业领域的实际应用。

期刊介绍: The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
