Concealed fastener roof or wall structure and method of assembly

Claim 1

In a barrier structure having spaced-apart horizontally extending structural elements, plural panel members extending transversely of said structural elements and being erected in side-by-side relation, said panel members presenting alternating panel webs and downwardly opening longitudinal ribs including joint ribs comprising overlapped and interlocked complimentary partial ribs of adjacent panel members, each of said ribs including a crest, depending sidewalls, and spaced-apart inturned base portions connecting said rib sidewalls to adjacent ones of said panel webs, the improvement comprising: each of said structural elements presenting sequentially arranged sets of uniformly spaced clips secured thereto, each of said sets including a fixed clip immovably secured to the structural element and plural movable clips, each capable of limited movement longitudinally of the structural element, the fixed clips of adjacent ones of said sets being spaced-apart at a distance corresponding to a selected modular width; the fixed clips of said structural elements being aligned relative to each other transversely of said structural elements; said clips being slidably connected to said ribs thereby to permit thermal movement of said panel members relative to said clips and transversely of said structural elements; corresponding longitudinal ribs of said panel members being connected to the fixed clips of said sets whereby any of said panel members having a panel width different from said modular width undergo transverse expansion or contraction to conform the panel width to said modular width, and said movable clips undergo limited movement longitudinally of said structural elements into registry with the associated longitudinal ribs thereby to relieve stresses introduced into the panel by transverse expansion and contraction thereof.

Claim 6

The method of attaching to the spaced-apart elongated structural elements of a building a succession of panel members each having intermediate ribs separated by panel webs and including complimentary partial ribs along opposite longitudinal edges thereof which are overlappable and interfittable with complimentary partial ribs of adjacent panels to provide joint ribs of like cross section, which method comprises: (a) securing fixed clips to said structural elements, adjacent fixed clips being spaced-apart at a selected modular width, being aligned transversely of said structural elements relative to one another, and being immovable relative to said structural elements; (b) securing movable clips to said structural elements at substantially uniformly spaced locations intermediate of adjacent ones of said fixed clips thereby to provide sequentially arranged sets of clips each including one of said fixed clips, said movable clips being capable of limited movement longitudinal of said structural element; (c) forcing ribs and partial ribs on a first panel into connected relation with one of said sets of clips by pressure exerted on the top surface of the first panel member, which connected relation allows thermal movement of said first panel relative to said fixed clips and to said movable clips and transversely of said structural elements; (d) placing a second panel over an adjacent set of clips with the partial rib thereof over a partial rib of said first panel member; (e) thereafter forcing the partial rib of said second panel member into interfitted relation with the partial rib of said first panel and into connected relation with the clip associated therewith by pressure exerted on the top surface of the second panel member, and forcing the intermediate ribs of said second panel into connected relation with the clips of said adjacent set by pressure exerted on the upper surface of said second panel, which connected relation allows thermal movement of said second panel relative to said fixed clips and to said movable clips and transversely of said structural elements; and (f) repeating steps (d) and (e) for each successive panel, if any; whereby panels having a panel width different from said modular width undergo transverse expansion or contraction to conform the panel width to said modular width, and said movable clips undergoing limited movement longitudinally of said structural elements thereby to relieve stresses introduced into the panel by transverse expansion and contraction thereof.

Claim 7

The method of attaching to the spaced-apart elongated structural elements of a building a succession of panel members each having intermediate ribs separated by panel webs and including complimentary partial ribs along opposite longitudinal edges thereof which are overlappable and interfittable with complimentary partial ribs of adjacent panels to provide joint ribs of like cross section, which method comprises: (a) securing fixed clips to said structural elements, adjacent fixed clips being spaced-apart at a selected modular width, being aligned transversely of said structural elements relative to one another, and being immovable relative to said structural elements; (b) securing movable clips to said structural elements at substantially uniformly spaced locations intermediate of adjacent ones of said fixed clips thereby to provide sequentially arranged sets of clips each including one of said fixed clips, said movable clips being capable of limited movement longitudinal of said structural element; (c) forcing ribs and partial ribs on a first panel into connected relation with one of said sets of clips by pressure exerted on the top surface of the first panel member, which connected relation allows thermal movement of said first panel relative to said fixed clips and to said movable clips and transversely of said structural elements; (d) placing a second panel over an adjacent set of clips with the partial rib thereof over a partial rib of said first panel member; (e) thereafter forcing the partial rib of said second panel member into interfitted relation with the partial rib of said first panel and into connected relation with the clip associated therewith by pressure exerted on the top surface of the second panel member, and forcing the intermediate ribs of said second panel into connected relation with the clips of said adjacent set by pressure exerted on the upper surface of said second panel, which connected relation allows thermal movement of said second panel relative to said fixed clips and to said movable clips and transversely of said structural elements; and (f) repeating steps (d) and (e) for each successive panel, if any; whereby panels having a panel width different from said modular width undergo transverse expansion or contraction to conform the panel width to said modular width, and said movable clips undergoing limited movement longitudinally of said structural elements thereby to relieve stresses introduced into the panel by transverse expansion and contraction thereof.
