Abstract: A Sheet Metal Structural Member has flanged openings formed therein to permit the passage of services therethrough. A grommet is provided that has a shape that corresponds generally to the plan form shape of the openings. The grommet has a peripheal wall and seating elements arranged about the peripheral wall to mate with the flanges that are located about the flanged opening. The grommet snaps into place and resists movement once installed. The grommet has radiused edges to discourage damage to service conduits or wiring carried therethrough.

Abstract: A rotary apparatus (20) for rotary forming of a web workpiece (12) and having a rotatable first roll unit (32) and corresponding rotatable second roll unit (34), a first die support (46) carried by the first roll unit (32), having a leading edge (51) and a trailing edge (52) respective to rotation of the first roll unit (32), a second die support (46) carried by the second roll unit (34), having a leading edge (51) and a trailing edge (52) respective to rotation of the second roll unit (34), the first and second roll units (32, 34) receiving a web workpiece (12) in a forming plane between the first and second roll units (32, 34), and in which each die support (46) includes a first part (46a) carried by the respective roll unit and including the leading and trailing edge and a second part (46b) having a platen surface for mounting a die, the second part (46b) being mounted on the first part (46a) for reciprocal motion transverse to the leading and trailing edges (51, 52).

Abstract: A construction panel for use in the erection of buildings comprising a panel of castable construction material of predetermined thickness, and having first and second sides; a plurality of structural members, reinforcing the panel on one side, at least some of the structural members comprising a generally linear edge, and a generally zig-zag edge, and a web extending between the linear edge and the zig-zag edge, the zig-zag edges defining apexes, and root portions; the apexes, being embedded in one side of the panel thereby securing at least some of the structural members to the panel; recesses formed in the web extending substantially from the apexes to the root portions; and, generally triangular indentations formed in the web throat portions adjacent to but spaced from the recesses. Also disclosed is a method of constructing a level portion of a building.

Abstract: A method of manufacturing a one piece integral metallic beam (22) having flanges (24), and a web (26) joining said flanges, the beam having been hot rolled from a heated metal workpiece (20) to produce an integral one piece beam having flanges and a web extending therebetween, the flanges having a predetermined first thickness, and the web having a predetermined second thickness less than the first thickness, and in which the web is heated to a hot forming temperature, without substantially heating the flanges and, the web is than passed through at least one metal forming die set (16), which is repeatedly closed on the web to form the web without forming the flanges. The method may also include the piercing of openings (28) through the web, and the forming of lips (30) around the openings, and also, the forming of a secondary product (52) from the portion of the web discarded from the opening, and also hot forging the lips (30) around the openings.
