- Flitch beam
A flitch beam (or flitched beam) is a compound beam used in the construction of
houses , decks, and other primarilywood-frame structures . Typically the flitch beam is made up of asteel plate sandwiched between twowood beams, the three layers being held together withbolts . In that common form it is sometimes referenced as a steel flitch beam. Further alternating layers of wood and steel can be used to produce an even stronger beam. The metal plate(s) within the beam are known as flitch plates.Advantages
Because flitch beams are significantly stronger than wood alone, they:
*require less depth than a wood-only beam of the same strength
*are much lighter than a steel beam of the same size
*can still be attached (e.g. nailed) to the rest of a wooden structureFlitch beams can also be created from existing
in-situ joist s or beams permitting easier renovations.External links
