Lightweight Sandwich Panel in Cold Stores and Refrigerated Warehouses
The use of sandwich panels has gained considerable recognition in the construction industry and more use of this composite structure is ever increasing. This study highlights and familiarizes the use of lightweight sandwich panel in refrigerated warehouses and cold storage facility and construction and the challenges such construction faces in warm climates considering the effects of thermal load. The study was commissioned by HAMK Sheet Metal Center, the steel research and development center in Hämeenlinna. The objective of the study was to investigate the thermal load on lightweight sandwich panel and how this load affects the working of the structure. Another aim was also to provide a structural arrangement that would reduce the effects of this loading on the structure. The loading is the thermal load of the sun, and the effects of this load are deflection of the span, wrinkling of the face, and core deformation, others include the shear failure of the screws and the stress induced by bending and intermediate supports in a multi-span system. The study is mostly on a general and descriptive level, reviewing and examin-ing existing and current practices on how to reduce thermal load on light-weight sandwich structures and providing ways to improving and modifying them. A thermal break, covering over the face of the panel, the use of flexible screws, sealing at the joints are existing practices geared towards reducing the effect of thermal load. The study provides further measures of reducing the thermal load by incorporating additional insulation on the panel face, further reduction of thermal bridge by using short screws rather than go-through screws from panels to the supporting structure and the use of PVDF paint as polymeric membrane.
