As part of the Malmo (Sweden) City tunnel infra-structure project the new Triangeln station in the heart of Malmo has recently been opened. By combining all the best attributes of sandwich composites, glass and steel, the architects have created two self-supporting entrances to the station that maximize natural light and create a real feeling of spaciousness both in the entrance and the escalator areas. Such is the innovative nature of the design that natural light even filters down to the platforms some 25 meters below street level. The flowing form of the entrances can be likened to a futuristic spaceship.
Both the station entrances were produced
by Gothenburg-based Skandinaviska
Glassystem AB (SG) who specialize in the
design and fabrication of façades and cladding
systems. Diab have worked closely with SG on several previous occasions including
the development of an award-winning
sandwich composite cladding system.
Lightweight, high strength performance was
a key requirement of the sandwich composites.
In addition to being capable of supporting
the weight of any maintenance crews and
equipment, the sandwich components also
feature hidden run-off channels for rainwater.
The sandwich composite elements were
based on Divinycell P, Diab’s recyclable,
thermoplastic foam. Divinycell P offers excellent
FST (fire, smoke & toxicity) properties,
a wide processing envelope and very
good fatigue properties.
To achieve the complexity geometry and
the +/- 0.5 mm tolerances that were required,
the core was accurately machined to shape
using a three axis CNC milling machine.
Reinforcements were then applied directly
to the core thereby eliminating the need for
