9 Claims. (Cl. 189-34) The object of this invention is to provide a metallic structure for flooring or other surfacing purposes, particularly adapted for commercial vehicles wherein adequate air circulation under refrigerated loads is required. A characteristic of the invention is the provision of maximum air circulation space within the structure itself. Also the structure comprises a primary unit and associated units `adapted to be mutually secured in a manner providing rigidity for the combination. A maximum ratio of load-bearing strength to weight is provided without the employment of corrugation, by providing, in the primary unit, and also in certain `associated tying units, a flat, i.e., horizontal, load-bearing surface from which upwardly extend vertical ribs, at least the major number of the ribs merging into opposed flanges which partially close the spaces or channels between the ribs and which overhanging flanges provide a oor surface without excessively wide grooves. This application is a continuation of my now abandoned copending application Serial No. 620,412, led November 5, 1956.

The invention will be described with reference to the accompanying drawings, in which:

Figure l is la transverse section through an assembly consisting of two primary iloor units mutually tied and tied to coacting side wall units.

Figure 2 is a transverse section through a primary floor unit having like longitudinal margins.

Figure 3 is a perspective view, in transverse section, showing one of the primary units of Figure 1, dotted lines connecting the marginal fragment of =a like unit.

Figure 4 is a perspective view, in section, of a side wall unit.

Figure 5 is a view similar to Figure 4, showing the side wall unit of that figure modified.

Figure 6 is a perspective view, in section, showing a tie unit to be employed in themanner shown in the succeeding gure.

Figure 7 is a transverse section broken away at its margins and showing two primary units tied, i.e., connected, by the units shown in Figure 6.

The construction now'to be described as to the units thereof is particularly adapted for strong aluminum alloy extrusion. Figure 3 illustrates a preferred form of primary unit. It consists of a base wall 1 from which rises a plurality of ribs 2, the major number of the ribs carrying at their tops opposed laterally-projecting load-carrying anges, so that each rib with its top is T-shaped. The T-shaped top of each-rib overlies channels between the ribs, and said channels are open for free circulation of the lair. In the structure of Figure 3 means integral with the margins of the structure is provided for rigidly tying together two like members when they areY brought together in reverse position. For such purpose the margins of the said structure are differently formed as now to be described.

Referring to the right-hand margin of Figure 3, it

be seen that a relatively deep rounded channel or groove Vcoacting unit shown inY Figure 3.

PatentedSept. 13, Y1960 ICC 3 is formed inthe under-surface of the load-carrying rib top 4, the latter being made up of the opposed ilanges at the top of the rib. This channel extends longitudinally of member 4. Rising from base member 1, in outwardly spaced relation to theouter rib 2, land extending 1on- `gitudinally thereof isa short rib 5 preferably havin-g its inner wall 5X downwardly inclined. At the opposite margin of the structure the outermost anged rib 2 carries a raised horizontal wall 6, the latter outwardly merging into a downwardly inclined extension 7 which carries =a generally L-shaped extension consisting of horizontal wall 8 and vertical wall 9, the top of which has a 'bead or rounded nose 1,0.

Wall 8 is raised vto a degree equivalent to the thickness of the basewaill 1. In the assembly of two like units `of the structure shown in Figure 3 they are abutted and as` indicatedk by dotted lines in that iigure the reverse Amarginsmay be interlocked, with wall S of the rst unit resting on the base wall of the second unit, wall 7 of the rst unitabutting the` inclined base 5X of rib 5 of the secondunit, and nose 10 of the first unit seated in groove `3 of the colacting unit.

lntFigurevl the said-two interlocked units are shown as interlocked with side wall or dashing units. Re-

ferring tothe right-hand side wall unit, it consists of a base wall 11 from which, rising to a degree required for arshing, is a vertical wall 12 spaced from a rib 13 which ,may have opposed anges or the single left-hand ange shown in. the ligure. Rib 13 carries a raised horizontal wall 14 merging into a downwardly inclined wall 15 which, in turn, carries the slightly raised horizontal wall 16 at the lower end of a vertical member 17 having a rounded nose17xiat its topv to enter the channel 3 of the Except for its relatively deep vertical wall 12X the left-hand side wall memberof Figure 1 is formedexactly the same as the righthand, end of Figure 3 and requires no further description. It is shown more clearly in Figure 4 and those elements which are the same for interlocking as those ,at the right-hand end of Figure 3 bear the same numerals.

' In some casesitV maybe desirable to reverse the posi- In such case that tie member the base wall 18 carries a central upstanding rib y19 having a load-bearing top 19X formedby vopposed anges, each vflange having an underlying longitudinal channelV or, groove at 20. At each side of rib k19 and spaced therefrom Ais a shallow rib 21 having an innerV downwardly inclined wall 21X. Thus when two like units are reversed in position their vertical walls 9 -may abut the .opposite faces ofthe connectorv `wall `19 withv thelbead or nose 10 of each wall 9 in its appropri- .'ate channel 20 of the connector, as shown in Figure 7.

When` the like-'units are reversed inthe manner shown in Figure 7 each marginL of the assembled structure, Will be @like that at` the right-hand end of Figure 3, and two of ltlieside wallmembersshown in, Figure 5 will interlock with, the, margins ofthe assembled primary when required.` f

The modiiiedprimary unit shown in Figure 2 is adapted structure,

,to receive either additional .primary members of the .supporting surfaceandineach casethe outermost flange is formed with achannel at 24 to receive the nose 10 of theunit shown in/Figure. 3 or the nose 1'7,X Vof the Lsidie wall unit shown in Figure 5,-and` at each margin the structure of Figure 2 carries within .the margin the same shallow rib shown at S in Figure 3 and for the same purpose.

It will be understood that various modifications may be made in the forms and arrangements of the elements illustrated in the drawings, without departing from the spirit of the invention.
