Abstract
A support device is provided for the preferred application of buckling opposing support of an I-joist having an erroneously cut hole in its web portion. The support device may have an approximate U-shape with two substantially parallel bridging structures combined by a structure that combines the bridging structures and provides an alignment reference with the chords. In the case where an erroneously cut hole is identified, the support device may be laterally attached to the I-joist such that both bridging structures flank the erroneously cut hole. Once the bridging structures are attached to the web, the bridging structures define with the remainder of the web a buckling opposing interface. The support structure is preferably monolithically fabricated from sheet metal and scaled in conjunction with dimensional standards of commercially available I-joists.
