Use of sandwich-panel technology for partition walls

Abstract

This thesis is devoted to the topic of partition walls in Finland, their requirements and main technological solutions. It explores the possibility of sandwich-panel use for partitions, emphasising modularity, faster assembly and potentially lower cost for construction projects. Thesis was commissioned by Ruukki Construction Oy. Conventionally, partitions have been made of masonry or wooden frames, seeing no significant change or advancement in technology over the past decades. Sandwich-panels, while typically used for facades or roof structures, could become an alternative solution. With advancements in material science and engineering, traditional designs could be improved to serve as partitions in certain building types. This thesis combines a literature review of relevant standards and publications and a case study, suggesting a sandwich-panel structure that could be utilised in office spaces as a partition wall. The results of the validation process indicate that it withstands necessary forces, acts well in fire and surpasses similar panels in acoustic performance. Moreover, the use of a modular structure offers reduced time and cost of assembly on-site. While this thesis does not provide a finalised solution and still requires additional validation by test and more reliable calculations, it serves as a foundation for further research on partition walls’ technology and, particularly, the potential use of sandwich panels in it.
