Abstract: An expansion joint cover apparatus (10) includes a cover plate (38) in covering relationship with the gap (12) between building sections(14,16). One edge (46) of the plate (38) is coupled to one building section (14) and the opposed edge (48) is slidably received in a recess (30) defined in the second building section (16) adjacent the gap (12). The second building section (16) includes a recess wall (34) between the recess (30) and the adjacent support surface (28). The apparatus (10) further includes a transition insert (44) mounted in the recess (30) against the recess wall (34). The insert (44) presents an insert wall (66) to provide a beveled transition between the recess area (30) and the support surface (28) in order to guide the plate edge (48) therebetween during relative movement between the building sections (14,16) and to protect the recess wall (34) from impact by the second edge (48) of the plate (38) during such movement.
