A reinforcement plate for attachment to an I-joist weakened by the removal of a portion of its web volume comprises at least one sheet-like portion for placement against a generally planar surface of an I-joist wherein an edge of the at least one sheet-like portion is configured to define at least part of opening in the reinforcement plate, said opening configured to be aligned with the weakened portion of the I-joist, wherein the edge of the at least one sheet portion comprises a continuous flange depending therefrom and upstanding from the plane of the at least one sheet-like portion. The joist plate may be provided as a pair of sheet portions, each having an aperture edge portion which together define the opening in the reinforcement plate. The invention further relates to an I-joist assembly comprising an I-joist weakened by removal of a portion of its web and a reinforcement plate attached thereto. The reinforcement plate may also have peripheral edge flanges which may project in the opposite direction from the aperture edge flange. |
