ABSTRACT:
An engineered or manufactured elongate wooden I-beam of the type having continuous upper and lower flange sections and a central web section therebetween is provided with a rectangular opening in the web along the span of the beam. A rectangular and open reinforcing frame constructed from at least four wooden pieces is securely positioned in the opening and is exteriorly dimensioned so that the height of the frame corresponds to the distance between the opposed interfaces of the upper and lower flange sections and the width of the frame is no less than the distance between the spaced apart web sections. This reinforced opening facilitates the passage of ductwork or the like laterally therethrough. Employing apertured I-beams of the foregoing description also facilitates a structural beam and bridging assembly where an elongate wooden bridging element can be employed by extending through and being interconnected to the frames of adjacent pairs of apertured joists.
