Metal roof construction

Claim 2

In a roof construction for a building, means for supporting a sheet metal roof cover which comprises, a plurality of laterally spaced elongated members each having an upper surface for supporting the cover and a wall extending normal to said surface, flange means spaced from said surface projecting laterally from the wall and extending beyond said surface, a sheet metal cover supported on the upper surfaces of the members and having a series of spaced openings therein, said flange means having openings therein which are normally in substantial alignment with respective openings in the cover, means for securing the cover on the surfaces comprising a pin extending through each of a pair of aligned opening in the cover and flange means and provided with an enlarged head overlying the opening in the cover, said pin being of a size to provide a snug fit within the opening in the cover and having a tapered portion converging downwardly passing through the opening in the flange means, the opening in the flange means being of a size relative to the tapered portion as to confine the pin against translational movement in any lateral direction but to allow the pin to rock in any direction about the wall of the opening as the head of the pin moves with the sheet in its expanding and contracting movements.

Claim 3

In a roof Construction in accordance with claim 1 wherein at least the base portion of the enlarged head of the pin is of spheroidal shape.

Claim 4

In a roof construction in accordance with claim 2 wherein the remaining portion of the enlarged head is of extended height and width to provide an effective snow guard.

Claim 5

In a roof construction according to claim 1 in which there are means for maintaining the pin against removal which comprises an enlargement adjacent the free end of the pin below the flange means, a second wall means, openings in the second wall means being no larger than the respective aligned means in the metal cover.

Claim 6

In a metal building wall assembly having an exterior metal sheath, comprising elongated structural support members in substantially parallel, laterally spaced relation, each of the support members having an outwardly facing first wall means against which the metal sheath engages, and a second wall means spaced inwardly of the first wall means, extending substantially parallel thereto and having at least a portion projecting beyond the edge of the first wall means, longitudinally spaced openings in the second wall means located in the portion projecting beyond the first wall means, openings in the metal sheath normally in substantial alignment with the respective openings in the second wall means, an elongated metal pin member extending through each pair of substantially aligned openings, the pin members each having a snug fit in the opening in the sheath and an enlarged head portion at one end bearing against the outer surface of the sheath, the portion of the pin passing through the opening in the second wall means tapering to converge toward its other end and fitting said opening so as to be incapable of translational movements in any lateral direction therein, the length of each pin between the openings in each pair, allowing it to rock about the wall of the opening in the second wall means as the one end of the pin moves with the sheath in its expanding and contracting movements.

Claim 7

In a metal building wall assembly having an exterior metal sheath, comprising elongated structural support members in substantially parallel, laterally spaced relation, each of the support members having an outwardly facing first wall means against which the metal sheath engages, and a second wall means spaced inwardly of the first wall means, extending substantially parallel thereto and having at least a portion projecting beyond the edge of the first wall means, longitudinally spaced openings in the second wall means located in the portion projecting beyond the first wall means, openings in the metal sheath normally in substantial alignment with the respective openings in the second wall means, an elongated metal pin member extending through each pair of substantially aligned openings, the pin members each having a snug fit in the opening in the sheath and an enlarged head portion at one end bearing against the outer surface of the sheath, the portion of the pin passing through the opening in the second wall means tapering to converge toward its other end and fitting said opening so as to be incapable of translational movements in any lateral direction therein, the length of each pin between the openings in each pair, allowing it to rock about the wall of the opening in the second wall means as the one end of the pin moves with the sheath in its expanding and contracting movements.

Claim 8

In a metal building wall assembly according to claim 5 wherein the first wall means each include a planar outer surface and a wall extending transversely thereto, the second wall means comprising a wall extending laterally from the transversely extending wall.

Claim 9

In a metal building wall assembly according to claim 5 wherein the structural support members comprise the roof rafters of the building.

Claim 10

In a metal building wall assembly according to claim 6 wherein the first and second wall means are in substantially parallel transversely spaced relation and connected by a transversely extending wall.

Claim 11

In a metal building wall assembly according to claim 5 wherein the openings in the second wall means are no larger than the respective aligned openings in the metal sheath.
