A panel construction for roofs and walls of buildings incorporates holding clips secured to supporting roof purlins in overlying relation to locator strips which are installed preliminarily to establish the spacing of the clips. After the locating strips are positioned, the clips are temporarily located by interfitting portions of the strips and clips, whereafter permanent fasteners are extended through the clips and strips and into the supporting structural element. The clips are double bent sheet metal elements having integral latch-type retaining portions. The panels, of sheet material, have hollow upstanding dovetailed latching ribs extending longitudinally of medial areas thereof, and complemental partial latching rib portions along their longitudinal edges and which interlock in sealed engagement with the complemental partial rib portions of adjacent panels to define dovetailed latching ribs at the joints of the adjoining panels. The latching ribs are shaped to conform to the retaining portions of the clips and during assembly are snapped into latched relation with the clips by pressing on the ribbed portions of the panels.
Securing means for the panels of a building panel structure comprising elongated relatively thin flat locating strips having coupling portions at their ends for assembling a plurality of such strips to a desired length, said strips being adapted to be installed in end to end relation lengthwise upon an elongated building frmae member, clip locating portions on surface portions of said strips which remain exposed when the strips are so installed, said clip locating portions being arranged at standardized longitudinally spaced distances, panel holding clips having base portions for attaching the same to supporting structure, additional locating portions on said base portions adapted to interfit with said clip locating portions on the locating strips, fastener-receiving portions on the base portions adapted for securance to an underlying building frame member by fastening means extending through such base portions and through the underlying locating strips and into the building frame member, and flexible latching means on said clips adapted for interengagement with coacting latching means on overlying panels.
A panel holding clip construction comprising a sheet metal member having an upstanding frame portion of generally inverted U-section defined by a top wall and side walls, base flanges extending laterally from the lower extremities of said side walls, a head including a pair of integral flexible latching arm portions, each of said latching arm portions being biased to and normally standing in a position extending angularly outwardly and downwardly from one of said side walls, said latching arm portions being pierced from said side walls, integral continuation latching arm portions extending inwardly and downwardly from the first mentioned latching arm portions, and abutment means on said side walls and latching arm portions limiting outward movement of said continuation latching arm portions in directions away from said side walls.
A holding clip for building panels and the like comprising a sheet metal member having a base portion adapted to be attached to supporting structure and having a retaining head of generally mushroom-shaped cross section defined by oppositely laterally protruding latching portions which are resiliently inwardly deflectable toward each other and which extend along lines parallel to each other, each said latching portion comprising a first leg extending outwardly from said clip and an integrally formed second leg extending inwardly toward said clip, said legs joining one another along a generally straight line of intersection, the lines of intersection of both latching portions being generally parallel to one another.
Means for securing panel elements to elongated building frame members comprising elongated relatively thin flat locating strips having coupling portions at their ends for assembling a plurality of such strips to a desired length, said strips being adapted to be installed lengthwise in end to end coupled relation upon a building frame member, clip locating portions on surface portions of said strips which remain exposed when the strips are so installed, said clip locating portions being arranged at standardized longitudinally space distance, whereby panel holding clips may be located on frame members and secured thereto in overlying relation to such strips, to enable retention of panel elements upon the frame member, said locating strips being formed of material having relatively low heat conductivity.
A panel holding clip construction comprising a sheet metal member having an upstanding frame portion of generally inverted U-section defined by a top wall and side walls, a base flange extending laterally from the lower extremities of one of said side walls, a head including a pair of integral flexible latching arm portions, each of said latching arm portions normally standing in a position extending angularly outwardly from one of said side walls, and limit means integral with said clip for limiting the maximum outward deflection of said latching arm portions.
The method of attaching to the elongated structural elements of a building or the like a panel having latchable retaining portions on its under surface, said latchable retaining portions including downwardly opening hollow ribs of generally mushroom-shaped cross section extending longitudinally of a medial portion of each panel, and also including partial ribs of corresponding cross section on the edges of each panel and which are interfittable with cooperating partial ribs of adjacent panels to define complete ribs of like cross section, which method comprises:
