Designed by ABCP architecture, the new structure aims to provide a protected playground that can be used as an ice rink in winter and doubles as a dek hockey or basketball court in summer. The strategic use of wood is this project’s greatest innovation. The service building has a light frame structure well suited for structures of this proportion and is covered with spruce siding which marks its relationship to the large roof. The rink cover on the other hand, uses a combination of glulam timber and steel to increase span without breaking the budget.
The glulam timber structure in tandem with the steel tensioning system permits a free span of 28 meters, despite its relatively low thickness. This large wooden veil rests on a steel colonnade extending on both sides of the playing surface. Without any additional elements, the bracing of the entire roof structure is integrated within the steel support system.
The unique shape of the roof is intrinsically innovational. The main trusses variable girths are sized to minimize wood volume across the structure. Each truss is constructed using two identical pieces of wood assembled to conceal the connections between the trusses, tie rods and columns. Dozens of hidden connectors are needed to connect trusses and columns. Angled in two different directions, columns are supported halfway between two trusses. The columns are off-kilter in all directions, yielding breathtaking results.
