AIRGRATE FLOOR PANEL SUB-PLENUM RETROFIT AIRFOIL

摘要

A retrofit airfoil for attachment to at least one of the girder members of an open-box load bearing frame supporting an air-grate raised access floor panel is provided. The open box flame includes a plurality of longitudinally spaced apart vertical girder-plate members and a plurality of longitudinally spaced apart transverse vertical reinforcing rib-plate members. The airfoil includes a sheet. The sheet has an upper edge, a lower edge, and a horizontal bend formation positioned along a longitudinal axis established therebetween. The bend formation defines an upper vertical face, and a lower inclined face. The upper vertical face includes a plurality of tongue and groove formations adapted for interlocking fitment with the vertically extending transverse reinforcing rib-plate members, so that the sheet is capable of being slidably attached to at least one of the girder members with the upper edge being positioned adjacent to the lower surface of the top plate. The vertical face of the sheet also includes at least one retainer to secure the vertical face of the sheet to the girder member.

1. In combination with an air-grate for a raised floor system, the air grate having a top plate supported on an open-box load bearing frame, the frame connected to a lower surface of the top plate, the open-box frame including a plurality of longitudinally spaced apart vertical girder members and a plurality of longitudinally spaced apart transverse vertical reinforcing rib-plate members, an interlocking airfoil for pressed fit attachment to at least one of the girder members, comprising: a sheet having an upper edge, a lower edge, and a horizontal bend formation positioned along a longitudinal axis therebetween, said bend formation defining an upper vertical face, and a lower inclined face, wherein said upper vertical face includes a plurality of tongue and groove formations adapted for interlocking fitment with said vertically extending reinforcing rib-plate members so that said sheet is capable of being slidably attached to at least one of said girder members with said upper edge being positioned adjacent to said lower surface of said top plate, and wherein said vertical face further includes at least one clip retainer to secure said vertical face of said sheet to said girder member.
