Abstract
A wooden joist is described. The joist comprises a wooden top chord, a wooden bottom chord, and a main section comprising at least one of wooden boards and wooden webs adhesively connected to the wooden top chord and to the wooden bottom chord to form at least one of an I-joist subsection and an open-joist subsection along the main section of the wooden joist. An end configuration at one end of the main section comprises a wooden post extending generally perpendicularly between the wooden top chord and the wooden bottom chord and is adjacent to the main section.
A wooden diagonal web extends diagonally from the wooden top chord to the wooden bottom chord. A first set of metal plates is in alignment on opposed sides of the wooden joist to connect the wooden top chord to the diagonal web. A
second set of metal plates is in alignment on opposed sides of the wooden joist to connect the diagonal web and the post to the bottom chord. A third set of metal plates is in alignment on opposed sides of the wooden joist to connect the wooden top chord to the post. An extension is defined by the wooden top chord extending beyond the diagonal web at an end of the wooden joist. The wooden joist is adapted to be in a top-chord bearing relation with a beam by the extension being on top of the beam.
A wooden diagonal web extends diagonally from the wooden top chord to the wooden bottom chord. A first set of metal plates is in alignment on opposed sides of the wooden joist to connect the wooden top chord to the diagonal web. A
second set of metal plates is in alignment on opposed sides of the wooden joist to connect the diagonal web and the post to the bottom chord. A third set of metal plates is in alignment on opposed sides of the wooden joist to connect the wooden top chord to the post. An extension is defined by the wooden top chord extending beyond the diagonal web at an end of the wooden joist. The wooden joist is adapted to be in a top-chord bearing relation with a beam by the extension being on top of the beam.
