From innovate treatments that improve the durability of timber and timber products, to new products designed for specific applications and connections that reduce assembly time and costs, this is an invaluable resource.View
ABUILD™ Flitches* provide a means of reinforcing timber to increase the span of timber beams. Abuild comprises of a 50 mm x 50 mm x 2.4 mm thick or 3.8 mm or 6.0mm thick steel angles, spot welded on to a standard toothed nail plate extending most or all of the length of the angle. Self install models using “grasshopper teeth” driven in with a hammer on site or pressed in the factory are both available. The steel angles are attached to the top and bottom of a timber beam which substantially boost the flexural strength as well as reducing deflection. The main difference from many previous efforts is that a substantial amount of steel is added to the top and bottom flanges where it is most effective.
A solution which is probably best suited to cost effectively modifying existing structures e.g. the general approach is a relatively common way to rectify a sagging beam.
Structural limitations - shear connection through the nail plate may be an issue in the do-it-yourself version of installation; connection to the steel upper surface is not as easy as timber.
Some potential for uptake in Australia for specific applications such as in high wind areas.
Structurecraft are a contractor specialising in the engineering, design detailing, supply and fabrication of complex, large and challenging timber structures. Though there is nothing especially groundbreaking about the panelized systems that they use, they occupy a worthwhile link in the supply chain that largely does not currently exist...
