A system and method used in residential and commercial construction of floors, ceilings and roofs, where a beam and hanger together support a joist/rafter to which sheathing is applied. Hanger design features include bendable stiffeners that provide pinching structural support for opposing sides of an engineered wood I-joist web after the joist/rafter is seated into the bridge of the hanger, providing a superior structural interface connection, less material cost, and no contact between the hanger and sheathing which reduces unwanted noise in finished construction. Additional strengthening of the structural/load-bearing interface between the joist/rafter and beam may include selected horizontally-extending dato, groove, cut, or other detail formed in the support beams during their manufacture/milling and rearwardly-extending protections on the hanger configured to engage the detail.

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; anda 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. 2. The system of claim 1 wherein said upper portion of said quantity of rigid hanger material further comprises at least one fastening hole. 3. The system of claim 1 wherein said quantity of rigid hanger material is pre-scored, facilitating rotation of said bendable stiffener components toward one another. 4. The system of claim 1 wherein said bendable stiffener components are further adapted to center said I-shaped joist against said support beam. 5. The system of claim 1 wherein at least one said bendable stiffener component further comprises least one reinforced edge. 6. The system of claim 1 wherein at least one said bendable stiffening component further comprises at least one tap point. 7. The system of claim 1 wherein said upper portion of said quantity of rigid hanger material further comprises at least two rearwardly-extending projections and said support beam comprises at least one indentation configured for interlocking engagement with said at least two projections, further strengthening said structural interface when such interlocking engagement between said rigid hanger material and said support beam occurs. 8. The system of claim 7 wherein said upper portion of said quantity of rigid hanger material further comprises a top end and wherein said at least two rearwardly-extending projections depend from said top end. 9. The system of claim 1 wherein said lower portion of said quantity of rigid hanger material further comprises at least one fastening hole through said bridge. 10. The hanger of claim 1 further comprising at least one fastening hole through said bridge and wherein said upper portion further comprises at least one fastening hole. 11. A system for providing a strong load-bearing structural interface in residential and commercial construction of floors using sheathing secured over support beams and supported joists connected to one another by hangers, said system comprising: at least two support beams;a plurality of engineered wood I-shaped joists each with a thin central web and opposing top and bottom flanges each having a width dimension larger than that of said web, said engineered wood I-shaped joists also each having opposite ends and said web having opposing sides; anda plurality of hangers each having a bridge configured for receiving and supporting one of said bottom flanges, said hangers also each having at least two bendable stiffener components positioned above said bridge and configured to create pinching contact with said opposing sides of said web after rotation of said stiffer components tower one another occurs, closely and directly engaging and securing said thin web of said I-shaped joist without having contact with said bottom flange thereof, reducing rotation of said engineered wood I-shaped joist when seated in said bridge, wherein when a different one of said hangers is secured to each of said opposite ends of each said engineered wood I-shaped joist, and each said hanger on one of said opposite ends of said I-shaped joist is also securely fixed to a different one of said least two support beams, rotation of each said engineered wood I-shaped joist relative to the ones of said support beams connected thereto is reduced after sheathing is applied, strengthening the structural interfaces between said engineered wood I-shaped joists and said support beams with less material cost, reduced installation time, and reduced noise in the finished construction. 12. The system of claim 11 wherein at least one said bendable stiffener component comprises at least one fastening hole. 13. The system of claim 11 wherein at least one said hanger is pre-scored, facilitating rotation of said bendable stiffener components. 14. The system of claim 11 wherein said bendable stiffener components are further adapted to center said I-shaped joist against said support beam. 15. The system of claim 11 wherein at least one said bendable stiffening component is further adapted with at least one reinforced edge. 16. The system of claim 11 wherein at least one said bendable stiffener component is further adapted with at least one tap point. 17. The system of claim 11 wherein at least one said hanger further comprises at least one rearwardly-extending projection and at least one said support beam comprises at least one indentation configured for interlocking engagement with said at least one rearwardly-extending projection, further strengthening said structural interface when such interlocking engagement between said rigid hanger material and said support beam occurs. 18. The system of claim 17 wherein said at least one hanger has a top end and wherein said at least one rearwardly-extending projection depends from said top end. 19. The system of claim 11 further comprising at least one fastening hole through said bridge. 20. The hanger of claim 11 further comprising at least one fastening hole through said bridge and at least one fastening hole not through said bridge.
