Abstract
A seamed metal roof is formed from an array of panels having lateral edges interconnected by rolled seams, and a plurality of clamps, each comprising a first elongate part having a mating surface, a longitudinal recess having dimensions like those of the seam, a second elongate part having a mating surface opposing the recess and the mating surface of the first part, and a fastener for drawing said parts together, to confine the seam in the recess.
Claims8
A clamp for reinforcing a rolled seam, of predetermined height and width, formed between apposed flanges of adjacent metal roof panels of a predetermined gauge, said clamp comprising
- a first elongate part having a head with a mating surface, a longitudinal recess beneath said head having a depth equal to the width of the seam, and a height equal to the height of the seam, and a foot extending below the recess and bounded by a plane offset from that of said mating surface by a distance equal to twice said predetermined gauge, and
- a second elongate part having a mating surface opposing said recess and the mating surface of said first part, and
- at least one fastener for drawing said parts together, to confine said seam in said recess and clamp said flanges together, face-to-face.
A method of reinforcing a roof, formed of panels laterally interconnected by rolled seams and secured to substructure at intervals by attachment clips joined to the seams, against wind uplift loading, comprising steps of
- identifying areas of maximum wind loading and
- applying a plurality of clamps to said seams, above said attachment clips, in each of said areas;
- each of said clamps comprising a first elongate part having a mating surface and a second elongate part having a mating surface opposing said mating surface of said first elongate part.
A seamed metal roof comprising
- an array of panels having lateral edges, neighboring panels being connected together along their lateral edges by rolled seams, and a plurality of seam clamps, each comprising
- a first elongate part having a mating surface, a longitudinal recess having dimensions like those of the seam,
- a second elongate part having a mating surface opposing said recess and the mating surface of said first part, and
- a fastener for drawing said parts together, to confine said seam in said recess.
