Lightweight thin walled profiled steel sheeting/dryboard (PSSDB) composite floor system

摘要

This paper describes an innovative lightweight thin walled composite construction system, known as the "Profiled Steel Sheet Dry Board (PSSDB) System" developed by the authors over several years of research work. The composite panel system consists of dry boarding, such as chip, ply, or cement board, attached to a core of profiled steel sheeting using mechanical screws. Floors in buildings or small bridges are possible applications for the PSSDB system and can now be built within a shorter period of time compared to the traditional methods and materials of construction. Apart from the speed of construction and earlier occupation time of buildings, and no wastage of temporary construction materials, the PSSDB system also appeals to many clients as the panels are lightweight (approximately a quarter of the weight of normal reinforced concrete slabs) with a reduced construction depth, meaning a reduction in the floor to floor height in buildings. The PSSDB system may also be used as load bearing wall panels, and as folded plate roof structure. This paper highlights on the Bondek Ⅱ/Cemboard Floor Panel (BCCFP), a derivative of the PSSDB system that has won three gold medals, i.e. the best overall invention award by the World Intellectual Property Organisation (WIPO), beating 58 other participants in the Invention & Design Competition (MINDEX/INNOTEX '97), held in Kuala Lumpur in 1997, a gold medal from the Ministry of Science, Technology and Environment, Malaysia in the same exhibition, and another gold medal received during the 26th Geneva International Exhibition on Invention, 1998. The application of the BCCFP system in flooring at the Hyatt Hotel, Sabah, Malaysia and other projects will be described in this paper.
