'lppli'cntion filed September 3,1924; Serial No. 735,674.

Be it knowna that; I, Bromine Hexwkn Rocnns a'Briti'sh subject; and" resident-of 9 Park Placegleondon; S. 1 England, have 5 invented certain: new and; useful Improve-' concretei floors; and, other; like structures made with metallic reinforcements According to the presentri'nvention thea'reinforce ment' employed consists of platesof sheet in etal out so as to: form tongues which can be bent out of the plane of the plate,-,these tongues; serving toi support or interconnect meta'l rods-or wires in'faplane-ata distance from that ofthe plate, suchrods,v wires. or the likebeihg: intendedvto: act as:- binding members for thezconcretqor inacases of reversed stress; as tension members The metal platefrom" which i the tongues are bent may have cross-piecesleft? extending- -diago-- nally' across the rectangles from which the tongues are out, whereby the plate will be materially strengthened.- without interfering with the; free passagav of the concrete through the plate, and-thethorough inter? connexion of; the concretebelowand above the surface oftheplat'e.-, The tongues of the plate serveto form roughly pyramidal cells for the concrete, while. the. intervening spacesform portions of. inverted: pyramids, and. it. has been? found by 1 experimentsewhen the-concrete is more. or'less divided up in this wayhy the, reinforcement that its .r re,- sistance. to deformation -or. fracture is very 40 high. The invention comprises the rein:

forcement per. se as? an 1 article: of manufacture-and alsoaconcrete structures embodying-g thereof,

Figure- 4 is. a; detail lview showingeafmethod I of. securing ;reinforcing2 rods-tor wires: to .the F hotly/1082's,?

tongues a are cut and bent upwardly, leav- Viously the sections might be shorter and Figure 5 is a plan view of a portion of a roadway with the reinforcement laid thereon in interconnected sections.

' Figure 6 shows a cross-section of a roadway made according to the invention.

Figures 7, 8 and 9 are partial views showing various arrangements of the reinforcing wires.

Referring first to Figures 1 to 4, it will be seen that the basis of the reinforcement consists of metal sheeting from which c ing diagonal members 7) in the cells between the tongues. In this particular example binding wires 0 are laid along the tips of thetongues and are secured by bending over portions of the tips. Figure 4 shows a suitable method of bending. Near the tip of each tongue a subsidiary tongue is cut and vthe metal of this tongue is bent as at d around the wire, or so as to form an eyelet through which the wire can be threaded. The actual tip a of the tongue is bent outwardlyin order to provide an additional anchorage for-the reinforcement in the concrete.

In layinga roadway for example, a number of sections of reinforcement made as abovedescribedare laid one beside another withtheir edges goverlapping, and the sections are? then interconnectedby wire lacing f carriedaround the roots of the tongues a from one: section to another. The sections may of course be bolted or riveted together if. preferred, but the method of lacing as above described is sufficient for most purposes.

The sections of the reinforcement of 7 any convenient dimensions, and in theexample shownin Figure 5 the sections are in strips each of the width of two cells. but of a length of eight cells. Ob-

wider, if preferred.

lllherremforcement is laid on a comparatively, shallowbedof concrete and then the concrete is filled in to a levelsomewhat aboyefthe, top of the reinforcement. In Figure- 6, for example, 72, represents the level, to which thei concrete is filled in, while the layer represents a road-surfacing layer or coveriapplied after the concrete has set.

It? wi11 .,be obvious that any additional 105 reinforcement required, for example ties of greater strength than the rods or wires 0, may easily be introduced into the reinforcement, for instance in the longitudinal and transverse channels between the tongues a. The reinforcing wires 0 may also be applied in various different ways. For example, Figure 7 shows how the wires may be passed diagonally through holes or slots as at is near the tips of the tongues. The wires may also be threaded straight through the holes is in the tongues as indicated in Figure 8, or the wiring may be provided as in Figures '7 and 8 combined in the one structure. As another alternative indicated in Figure 9, the wiring of Figures 1 to 6 may be retained while the tongues a have holes or slots through them at a lower level as at Z, through which additional wires may be passed, either longitudinally and transversely as shown, or diagonally if preferred, as in Figure 7 It is unnecessary to illus trate all the possible ways in which the wiring may be combined with the tongues, but it is thought that the illustrations above referred to will su'liice for this purpose. The body portions of the tongues a may have subsidiary tongues cut and bent out from them if required, as indicated at 0 in Figure 1. These tongues 0 provide further projecting engaging members for the concrete and they may also serve as a means of supporting additional reinforcing bars if required. Instead of being flat in the spaces between the principal tongues a, the sheet metal plate may be stamped with ridges or the like for the purpose of increasing its stiffness, and the tongues (it themselves may be stamped out with ridges therein for the same purpose, although this is not generally necessary.

Where the binding rods or wires 0 cross one another they may be interconnected either y wire binding as indicated at n, by spot welding or in any other convenient manner. The wires may also be spotwelded, for example, to the tongues instead of being passed through slots or otherwise secured thereto as previously described. It is not essential that the diagonals marked 6 in the drawings should be left between the tongues, and when these diagonals are not required the tongues may be cut out by simple X-shaped slits being formed in the plate. It is preferred, however, to leave the diagonals for strengthening purposes.

hen the reinforcement is to be used for concrete flooring in buildings for example, the apertures in the plate may be closed from below by another plate applied at the bottom and connected, for example, by spot welding at convenient positions. The additional plate will then serve to support the concrete within the reinforcement formed in accordance with the present invention.

The tongues 64 may be bent up from the plate at any convenient angle thereto, but as a rule it will be found most convenient for the tongues to be bent up to from 45 or more from the horizontal, and in the example shown in the drawings they are bent up to about 60.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1.
