Definitions

  • the present invention relates to improvements in metal structural elements, relating more particularly to steel structural members especially useful for constructing floors over which freight is moved or upon which it is stored, such as floors for freight cars, trucks, warehouses and the like.
  • the present structural element can withstand hard usage without requiring repair or replacement but is economical to manufacture.
  • Another object of the invention is to provide erally channel-shaped steel floor member having" a load-bearing panel containing strengthening indentations or depressions filled with a wear resistant non-metallic substance so that the floor.
  • Still another object of the invention is to pro vide a floor composed of a plurality of floor members of the aforementioned general character and to provide such members with a structure permitting them to be placed side by side conveniently and effectively but spaced from each other to provide grooves or openings for receiving nails.
  • strengthened. structure it is adapted to withstand its load without support from adjacent members so that the floor not only remains smooth but dishing is almost entirely avoided.
  • the nail receiving grooves do not spread and are not otherwise deformed so that their effective operation is not impaired or prevented by dishing of the floor members as has often been the case heretofore.
  • each floor member possesses a Finally, it is an object of the invention to provide an improved metallic nailable interior surface for freight conveyances or the like in which nailing grooves, as well as indentations or depressions in the load-bearing surface, are filled with a mastic or cementitious material rendering the freight conveyance suitable for carrying all kinds of ladingsincluding loose or unpackaged cargoes "such as grain; sand, etc. without loss through cracks, grooves, nailholes, split structural elements and the like; and to provide a surface possessing and retaining a relatively highcoefficient of friction as compared with slippery all-metal surfaces or composite:- metalzl and: wooden surfaces, so that flo'ating loads mayfibe .a

  • Figure 2 is an isometric view of a portion of the. floor:;structure of the freightcar illustrated in. Figure l and is taken alongtheline 2-2 of. Fig: ure l in;the direction of'thearrows.

  • the angle members l3 are welded or otherwise firmly secured to the frame of the car so that the sheathing i2 and I6 and the angles l3 provide a rigid wall structure enclosing the interior of the car.
  • a curved cover plate I1 having a rounded corner is attached to the sheathing l2 and [6 at the corners of the car in order to reinforce the structure'and "to concealathe-angl member's I3.
  • the reference numeral l8" designatesan inner wooden side wall or lining which is spaced from the outer metallic wall I2 and is held in place by suitablewstuds or upright supporting members spaced at intervals, two such studs being shown at 2El-and 2 I
  • the end wall of the car also is provided *witli a'wooden inner wall or lining l9 placed directly-against the outer metallic end wall lfia.
  • Thewoodenzinner wall or lining I8, 19 preferably rests upon suitable supports such as th'e side'anglemembers ill and H and may be reinforced if desired.

  • such groove .- provides ready and convenient means fornailing; fasteningoules taining elements to the floor, such for instance, as the block 35.
  • the nailing grooves are filled with a relatively soft, mastic or gummy material 49 acting as a sealant but which i adapted to receive a nail.
  • each of the contiguous floor members 21 rests upon one of the side rails or angle members It or I l.
  • the floor members 21 are also supported by longitudinal frame members 23 as well as by the central longitudinal sill member 25.
  • the frame members 23 are preferably Z-shaped and are supported by the cross-beams or cross-bearers (not shown) forming a part of the car frame and mentioned hereinbefore.
  • the reference numerals 26 and 28 designate a pair'of wooden strips disposed between the central sill member 25 and the floor members 21.
  • each member 21 may be riveted to the angle members in or H while its intermediate portion may be welded to one or more of the 'Z-shaped supports 23. It will be noted that each member 21 is attached to its support independently of its adjacent member. Thus, such members are easy to repair or replace.
  • the increased strength of the present floor members 21 prevents dishing or deformation thereof especially at the panel portion 29. Consequently, the nail receiving grooves are not spread or otherwise distorted by such dishing and remain fully operative throughout the useful life of the fioor members.
  • the floor members can be secured together to strengthen the floor 9 especially to make it more rigid and resistant to swaying or buckling longitudinally of the conveyance.
  • bridge-Welds may be used at spaced points along the top of each nailing groove to secure the floor members to each other.
  • the strengthened structure of each member 21 causes it to resist dishing. Accordingly, in this case, too, the nail receiving grooves do not spread and are not distorted.
  • each floor member 21 The outer or load-bearing surface of the panel 29 forming a part of each floor member 21 is provided with a plurality of indentations or de pressions 36 herein sometimes referred to as reinforcing ribs.
  • these indentations and depressions are somewhat elongated, that is, they are relatively long as compared with their width.
  • the indentations or depressions 38 are provided with a round or semi-circular contour in cross-section but possess upwardly inclined converging end walls which meet to provide a rounded end point smoothly merging into the surface of the panel 29.
  • the indentations or depressions 36 are spaced from each other longitudinally throughout the length of each member 21, the major axis of each indentation running transversely of the member 21.
  • the aforementioned arrangement of the indentations or de-' pressions 36 disposes the major'axes thereof at right angles relative to the parallel longitudinalaxes of the webs 30 and 3
  • the mem bers 21 are strengthened against longitudinal deformation of the panels 29 inasmuch as the transversely extending depressions 3B stoutly resist such deformation.
  • provide ample strength for resisting of the floor 9 do not dish the floor.
  • transverse deformation of the member 21 if lift trucks are run lengthwise of the boxcar or if such transverse loading is otherwise imposed.
  • axes of the depressions 36 could run obliquely relative to the longitudinal axes of the webs 39 and 3
  • shape of the depressions or indentations 36 could differ from that illustrated provided that the surface of the panel 29 is kept smooth. Principally because of the elongated shape of the" vmember 21, it is much better to provide a some what elongated indentation or depression 39 sothat it may extend across substantially all ofa the width of the panel 29 in order to strengthen.
  • the depressions or indentations 36 are filledwith an initially moldable non-metallic, mastic.
  • the bonding agent a bituminous, aqueous emulsion containing an emulsifying agent as well as colloidal clay and asphalt.
  • This bonding agent is preferably painted on or otherwise applied to, the walls of the depressions or indentations 36' prior to filling them with the moldable material itself.
  • the latter may comprise a graded light-' weight cellular burned argillaceous, chemically inert aggregate, such as siloxide rock or a volcanic ash.
  • the asphaltic base may be a prod uct similar to the bonding agent; that is, a bituminous, aqueous colloidal clay but, unlike the bonding agent, also containing a non-mineral fibre.
  • the setting powder may be air entrained cement blended with other cement powders, such for example as a Portland puzzolan-type cement.
  • the ingredients mentioned may be mixed with water to form a mortar-like product which can tion 36.
  • One suitable material comprises an as-v phaltic bonding agent, an inert aggregate, an asphaltic base, and a cementitious setting agent, More particularly, I have successfully employed emulsion containing a.”
