It gets cold on the beach during the winter season, so now Toronto is doing its version of the Winnipeg Warming Hut competition with its own Winter Stations Design Competition. Among 2015’s winners were The Steam Canoe, a design from OCAD University in Toronto. The team, led by Environmental Style Assistant Professor Mark Tholen, won an Ontario Wood Functions! award recently.
Composed of wood panels and architectural timbers, OCADU’s design resembles that of a canoe that is upside down, resembling a dome on the interior in which the public can take shelter. Evacuated solar tubes placed at the rear of the structure were created to turn snow to steam, resulting in a fog halo that surrounds the ‘steam canoe’.
However these are not regular wood panels, this is a brand-new technology that introduces a new method for laminating wood. It is developed with a metal attachment system called Grip Metal, which has small extruded hooks that go into the wood, turning it into exactly what they call Press Laminated Timber panels.
The procedure of sandwiching 2 layers of 3mm Oak and one layer of 19mm Spruce was enabled by the mechanical fastening of two Grip Metal ™ layers that results in a type of metal Velcro ™. It was established by Nucap Technologies. This method requires that a thin continuous steel sheet with grip hooks on the either side of the sheet’s faces is pressed into the veneer and core lumber in this press rolling method.
It obviously was developed for the automobile market, however can in fact, secure any products that are softer than the base metal utilized, which if course, wood is. It has some genuine benefits over the more conventional glue laminated panels, in that it is reversible.
The panels are assembled without making use of any glue and even though they have a more powerful bond than standard chemical adhesive approaches, the parts can be separated at the end of its life-time into its pure product origins of wood and metal, making this an ideal innovation in product, procedure, application, item, and sustainability.
It was likewise relatively easy to curve the panels, merely by flexing them as it went through the rollers, which removed the requirement for a structural frame. The Steam Canoe displays many of GRIP Metal’s core capabilities. Including providing a bonding layer to wood laminates and structures that equate the core abilities of metal substrates to its laminate partners; bond strength, shear and torsion resistance. This is done without trading off the need for lighter weight and flexibility, that today’s styles require.
It is exceptional that this all progressed from a product initially created to hold brake pads in place, now cranked out in big sheets. The Steam Canoe job is probably the very first of numerous interesting projects that are made of PLT. This is a sign of cool things to come!
