TWO-PART HOLD-DOWN APPARATUS WITH SLIP JOINT FOR SEAMED PANEL ASSEMBLIES Abstract A two-part hold-down apparatus for an assembly of seam-connected panels (11, 12) firmly secures the panels at the seam (13) to the supporting structure while at the same time allowing for thermal expansion and contraction movement thereof. An upper fastening member (31) has an upstanding web portion (32) with a top flange (33) extending out from an inner face that is firmly secured in a seam (13) joining the adjacent sidewall portions of two panels and extends down to the supporting surface. A bottom pocket (36) extends up from an outer face of the web portion and terminates in a top rim (37). A lower fastening member (41) covered by a panel (12) has a depending end section (44) freely slidable in the pocket and a top section (45) that bears against the rim to exert a hold-down pressure thereon to form a slide joint between the two members. A base (42) of the lower fastening member is firmly affixed to the supporting structure.
