Definitions

  • FIG. 14 is a sectional elevational view of a modification of truss ange
  • FIG. 21 is a sectional elevational view of a modification of a box beam employing channel flanges ⁇ and double lacing..
  • the lacing 24 may be assembled to the flanges in a plurality of arrangements. To rform a truss or beam of I section the lacing is interposed between anges 10 as shown in FIG. 7, the ends of the lacing being abutted in t-he recess 22 of the rib 18 and welded thereto.
  • the lacing struts 24 may be yarranged in several patterns, two such arrangements being shown in FIGSL 1 and 2 and the planar ends of the lacing struts are trimmed such that the edge 26 is parallel with and fully engages the recess 22, the smaller aroaaez the included angle between the strut and ange the greater the length of the edge 26.
  • FIG. 8 illustrates ⁇ another arrangement of lacings with a pair of anges 10 to produce a box beam.
  • lacing ⁇ 24 is interposed between the opposed ends of the flanges, the ends of the lacing abutting the surface 16 and being welded thereto.
  • the lacing 24 is arranged as in FIG. 3 where a uniform pitch zig-zag pattern is illustrated, however, the beam strength may be increased when supported in cantilever fashion as in FIG. 4 by decreasing the pitch of the lacing near the supporting end.
  • FIG. 15 illustrates how three beams 50 ⁇ may be employed to form a structure consisting of an elevated cross member supported at each end by a vertical column.
  • the horizontal cross member may be allixed to the columns simply by the use of overlapping perforated aluminum strips 54 which are bolted to the column and the cross member as illustrated and by the angles 56 which are bolted to the chord angles of the columns and the plates 52 of the cross beam.
  • a fabricated beam construction comprising, in combination, a pair of parallel, spaced, generally planar, elongated aluminum flanges, a planar lacing abutting surface defined on each orf said flanges in opposed relation, said lacing abutting surface extending substantially the length of and parallel to the associated flange, a plurality of aluminum lacing members interposed bet-Ween said flanges and havi-ng ends affixed to said flanges maintaining the spacing 4between said flanges, said lacing ends including a planar surface parallel to andabuttingly engaging a flange lacing abutting surface, a longitudinal shoulder surface defined on each of said flanges adjacent and perpendicularly intersecting the lacing abutting surface thereof defining a right angle intersection upon said flanges, said lacing ends being of a transverse width less than the transverse width of said lacing abutting surfaces and coplauarly engaging said abntting surfaces whereby a lacing
  • a ymethod of forming a relatively small circular hole in a substantially planar member :of rela-tively thick material comprising the steps of displacing the material of the hole location in oppositeV directions from -a diameter of the hole to be formed by a flowing of the material to define the hole and a pair of 'arcuate ⁇ ridges of displaced .material adjacent the periphery of the :hole projecting from lthe plane of the member on a common side thereof to thicken said planar member adjacent the lhole in a ⁇ direction transverse to said diameter and sizing and trimming said hole upon displacing of the 4hole material.
