Jig for forming structural building member
A jig 1 for wooden beam 20 construction, the jig 1 adapted to hold in position an upper beam 21 above a lower beam 22 , in or overlapping its vertical footprint 22 a , the jig 1 including a fastener dispenser 30 mounted on a translocatable carriage 40 , the fastener dispenser 30 adapted to mechanically attach the upper beam 21 and the lower beam 22.
1 . A jig for wooden beam construction, the jig adapted to hold in position an upper beam above a lower beam, the upper beam in or overlapping the lower beams vertical footprint, the jig including a fastener dispenser mounted on a translocatable carriage, the fastener dispenser adapted to mechanically attach the upper beam and the lower beam, wherein the jig includes at least one upper dispenser unit and at least one lower dispenser unit, the upper and lower dispenser units each including a fastener dispenser, the upper dispenser unit being adapted to be mounted above the wooden beam and the lower dispenser unit being adapted to be mounted below the wooden beam, each of the upper and lower fastener dispenser units being adapted to eject a fastener at a non-perpendicular angle to the respective longitudinal axes through the respective upper and lower beams into one of the mid supports to mechanically attach the upper beam and the lower beam.
2 . The jig for wooden beam construction as claimed in claim 1 , wherein the upper beam is adapted to be attached indirectly to the lower beam with an arrangement of mid supports bridging the upper and lower beams, the mid support in the form of wooden blocks or boards.
3 . The jig for wooden beam construction as claimed in claim 1 , wherein the fastener dispenser includes a pair of dispenser units orientated so that the fasteners are ejected at a non-perpendicular angle to a longitudinal axis of the upper and lower beams.
4 . The jig for wooden beam construction as claimed in claim 1 , wherein a method for construction of the wooden beam includes applying adhesive to the upper and lower wooden beams and clamping them together with the mid supports interposed between the upper and lower beams in the jig, locating the translocatable carriage at various points along the wooden beam in line with the mid supports and inserting fasteners through the upper and lower beams into the mid supports with the fastener dispenser to mechanically secure the wooden beam together.
5 . The jig for wooden beam construction as claimed in claim 1 , wherein the translocatable carriage is adapted to translocate along the jig on an upper and lower rail.
6 . The jig for wooden beam construction as claimed in claim 1 , wherein operation of the translocatable carriage and fastener dispenser is partially or fully automated.
7 . The jig for wooden beam construction as claimed in claim 1 , wherein the translocatable carriage includes a roller adapted to roll across an upper surface of the upper beam.
8 . The jig for wooden beam construction as claimed in claim 7 , wherein the roller is adapted to be located adjacent the dispenser units.
9 . The jig for wooden beam construction as claimed in claim 4 , wherein, the adhesive is applied to only near-upward or downward facing surfaces, being between zero and 15 degrees from vertically facing.
