Larger cross sections can be made via special wood manufacturing processes.
Curved laminated timber beams.
As a rule of thumb the thickness of plank required is the radius 200 i e.
Factory made members can be formed into any practical shape and any desired size.
Glulam beams that curve in plan use plies that are oriented vertically therefore the finished height of the beam is based on standard glulam widths.
A nine metre radius will require a plank thickness of 45mm but a two metre.
Differing radii are achieved by adjusting the clamp layout and using different thicknesses of timber.
Radial curved elliptical shapes and reverse curves are all possible.
We can even fabricate complete circles.
The tightness of the radius will determine the thickness of the laminations.
They resist checking and twisting because of the use of multiple plies of kiln dried lumber bonded together with waterproof phenol resorcinol adhesive.
Rigidply rafters inc has been manufacturing glue laminated products since 1954.
Curved beams creativity involves thinking outside the square and wouldn t it be great to work with a material that allows you to do just that.
The thinner the planks are the easier they are to bend which allows tighter radii to be achieved.
Laminated beams are superior in all strength characteristics to solid sawn lumber.
Use other member stress combinations e g.
