Abstract:
1. A structural interface strengthening system used mainly in residential and commercial construction of floors in a structural interface between a support beam and an engineered wood I-shaped joist having a thin central web and opposing top and bottom flanges each having a width dimension larger than that of said web, said structural interface strengthening system comprising: a support beam; an engineered wood I-shaped joist having a thin central web and opposing top and bottom flanges each with a width dimension larger than that of said web; and a quantity of rigid hanger material having a lower portion configured as a bridge that closely receives and supports said bottom flange of said engineered wood I-shaped joist, said quantity of hanger material also having an upper portion configured with opposed stiffener components bendable toward one another, wherein when said engineered wood I-shaped joist is supported by said bridge and said upper portion of said rigid hanger material is secured to said support beam, and said bendable stiffener components are rotated toward one another, closely and directly engaging and securing said thin web of said I-shaped joist without having contact with said bottom flange thereof, rotation of said engineered wood I-shaped joist relative to said support beam is reduced during weight transfer across said structural interface created by connection of said support beam, said engineered wood I-shaped joist, and said quantity of rigid hanger material, providing a strong structural interface with less material cost, environmental benefit, and reduced noise in finished construction.
