Abstract
An engineered perimeter rim board with machined or otherwise-formed modular recessed receptacles receives and secures I-joists and other manufactured joists at pre-designated spaces along the length of the rim board. The rim board provides pre-measured joist securement locations and structural enhancements by “locking” the joists into position. Receptacles machined/cut into the rim board may be of various shapes, such as a rectangular recess with a flat planar back wall, a profiled recess with curved top and bottom compartments, and/or an angled recess wherein two sidewalls converge to create a recess without a back wall for receiving joists at positions other than perpendicular to the rim board. The preferred 90-degree receptacle profile provides an I-joist web receiving slot for additional lateral support to help prevent joists from buckling, twisting or rolling over.
