Abstract
Interlocking cast glass assemblies are a promising solution for architectural cast-glass applications aiming for high transparency and a reversible structure that allows the reuse of the glass components (Oikonomopoulou et al.,2018; Oikonomopoulou,2019b). In such a system, an interlayer material between the glass elements is essential, to assist the homogenous stress distribution and account for the surface microasperities of the glass elements. Towards circularity, this material should be dry (and not an adhesive), allowing for the eventual disassembly of the system. Previous experimental work by (Aurik at al.,2018; Oikonomopoulou at al.,2019b) has focused on the use of PU and PVC interlayers as suitable candidates; the focus in those studies has been solely placed on the mechanical performance of the interlayer material. This research provides a review of potential material candidates suitable for interlayers of an interlocking cast glass assembly based on a set of revised design and performance criteria that are divided into primary and secondary. Furthermore, the impact their unique material properties have on the potential application of the interlocking system is examined. The whole process, from fabrication to construction of the entire assembly, based on an assumed building scenario, is presented in a chain reaction manner, whose starting point is the interlayer itself. After defining the design criteria the interlayer should adhere to, the proposed candidates are: PETG sheets (Vivak®), Neoprene, Aluminum, Laminated Polyurethane (PU) and a Soft-core aluminum interlayer. The unique properties and fabrication challenges of all five proposed interlayers are considered, as well as their properties in relation to assembly, which leads to the development of two distinct assembly sequences. The main distinction concerns the interlayers that risk creeping and those that do not. The research concludes with a comparison between the interlocking assembly and the other glass block assemblies currently applied.
互锁铸造玻璃组件是建筑铸造玻璃应用的一个很有前途的解决方案,旨在实现高透明度和可逆结构,允许玻璃组件的重复使用(Oikonomopoulou等人,2018;Oikonomopoulou, 2019 b)。在这样的系统中,玻璃元素之间的夹层材料是必不可少的,以帮助均匀的应力分布和解释玻璃元素的表面微凹凸。朝向圆形,这种材料应该是干燥的(而不是粘合剂),允许系统的最终拆卸。(Aurik at al.,2018;Oikonomopoulou等人,20119b)专注于使用PU和PVC夹层作为合适的候选者;这些研究的重点仅仅放在夹层材料的机械性能上。本研究基于一套修改后的设计和性能标准(分为主要和次要标准),对适用于互锁铸造玻璃组件中间层的潜在候选材料进行了回顾。此外,还研究了它们独特的材料性能对联锁系统潜在应用的影响。整个过程,从制造到整个组装的施工,基于假设的建筑场景,以连锁反应的方式呈现,其起点是中间层本身。在确定中间层应遵循的设计标准后,建议的候选材料有:PETG片材(Vivak®)、氯丁橡胶、铝、层压聚氨酯(PU)和软芯铝中间层。考虑了所有五种夹层的独特性能和制造挑战,以及它们与组装相关的性能,从而开发了两种不同的组装序列。主要的区别在于有蔓延风险的中间层和没有蔓延风险的中间层。研究的最后,比较了联锁组件和目前应用的其他玻璃块组件。
