UNITED STATES JOSEPH SO'I'Y, OF NEW YORK, N. Y.

FLOOR CONSTRUCTION FOR REENIORCED CONCRETE.

Application filed March 10, 1922. SeriaLNo. 542,665.

To all whom it may concem:

Be it known that I, J osnPH So'rY, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Floor Constructions for Reenforced Concrete, of which the following is a specification.

- This invention relates to reenforced -floor constructions and has for its main object to provide such a construction and system of a buildlng and reinforcing concrete floors.

which will do away with the horizontal beams used at present to carry part of the load on the floor construction.

Another object of this invention is to provide such a system which will make the top and lower surfaces of the floor. construction perfectly horizontal and parallel to each other and thereby make the necessary forms and frames for the concrete more economical, simpler and cheaper.

Another object again is to make such a floor construction which will be easier to build, lighter in weight and cheaper in cost than those used at present for similar pur-' poses.

Still further objects of this invention will be apparent while the description of my in vention proceeds.

For a'full description of the invention and the merits thereof and also to acquire a knowledge of the details. of construction of the same for effecting the various results mentioned hereinbefore, reference is to be had to the following description and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the-invention is illustrated in the accompanying drawings, in which Fig. 1 is a plan view. of a floor construction made according to my invention,

Fig. 2 is a vertical sectional view of said floor construction, the section being taken on the line 2--2 of'Fig. 1,

Fig. 3 is a more detailed plan view of a connecting plate applied to the columns of the building to which my reenforced concrete floor construction is to be built,

Fig. 6 is avertical cross sectional View of the floor construction usedwith temporary iron beams, the section being taken on the line 66 of Fig. 5,

Fig. 7 is a detail view of one of the connecting plates employed in the above mentioned second modification of my invention, Fig. 8 is a diagrammatic plan view of my invention employed in connection with built stone or brick columns-,-

Fig. 9 is-a diagrammatic plan view of a portion of the floor constructed according to my invention and joined at the corners of the building to built brick or stone walls.

Fig. 10 is a similar View to Fig. 9 showing I said connection at the sides of a wall, and Fig. 11 is a vertical cross sectional View of such a construction, the sectionbeing taken on the line 1111 of Fig. 10.

Referring more closely to the drawings, 12 indicates the column of the building, in this case it being made of structural steel. At the center line-of the floor to be constructed, I apply connecting plate 13'and fasten it to the column 12. This. plate is shown on an enlarged scale in Figs. 3 and 4 and is preferably made ofcast -iron. In this case it is shown as of octagonal shapeand around its sides on its upper surface it has lugs 14 into which are connected the single rods of reenforcing bands 15. Said rods are preferably formed into an end loop 16 thrown over the lugs 14 and secured by'wire. clasps 17. In order to take up the possible bend and loose.- ness of the rods 18, keys 19 and '20 are employed into the loop 16 and the rods can be pulled tight by driving said keys against each other. v

In order to construct the concretefioor, I

first employ reenforcing bands 15 in two directions, connecting the columns in their lines, and in the diagonals of the squares formed by their lines. These bands will be' connected to the plates 13 in the manner ex-' plained hereinbefore. In the diagonal direcadditional' rods at the. twosides of the onginal bands, distributing them at a larger distance from each other than the rods of the original bands are placed. Said additional diagonal band rods are shown in Fig. 1 marked 21. and they are bound into a'rectangular or square stiffening and reinforcing rod shape 22 placed around each column. Further additional reinforcing rods 23 and 24 may be employed at still larger distances-from each other in the two diagonal directions at the two sides of the and properly fastened and also secured to each other, the concrete may be poured and the floor isready.

In case a temporary steel beam construction is needed, horizontally connecting, reinforcing and stifiening the columns of the building while the erection work is going on,

the construction shown on Figs. 5 to 7 may be employed. In this modification 12 again represents the structural steel columns of a building. Between said columns a system of horizontal stiffening beams 2525 are applied, which are useful only while the erection is going on and which may-be lighter and lower than the beams usually employed if they have to carry the load of the floor.

' Specially shaped cast iron quarter plates 26 are in this case employed in the four corners formed by the reinforcing beams 25 and fastened to the columns in the center line of the floor by their extensions 27. These quarter plates are similarly constructed to the plates 13 described above and the load carrying and reinforcingbands are secured to them in the same way asthey have been secured to the plates 13 in the construction detailed hereinbefore. Load bands 15 and additional rods 21 are employed in a similar manner as mentioned above, only the stiffening rectangular shapes 22 are replaced here by sin gle sides- 28., The field reinforcements for the floor run in this case in the directions of the columns and not in their diagonals and 4 are represented by the rods 29 and 30.

My system of reenforced concrete floor construction may also be applied to buildings with stone or brick columns and walls. Figs. 8 to 11 show some details of such constructions. In Fig. 8 the numeral 31 represents the outlines of a brick or stone column, 32 indicates the octagonal connecting plate built into the column in the center line of the floor. The construction of these connecting plates and the method of securing the rods to them is entirely similarto those described above. A center rod 33 is built into the column and through a suitable hole in the center of the connecting. plate to further secure said plate in the column, and will be described presently..

At the corners of the building-the rein forcing rods are connected to quarter platesshownon Fig." 9 and said quarteP-plates are secured into the corners of the walls byextensions 34 and 35 which may be furthersecured into the walls by the vertical rods in this-case three of them being shown. 1 Figs. 10 and llshow the construction used and horizontal so that v as the boards need not afterwards be re eases having stone or brlck walls. Here again a specially formed connecting plate 36 is used. similar to thoseused hereinbefore and con nected to the wall by extensions 37 and 38 through which pass the vertical rods 33. Said rods are built into the wall or column of the building and serve to further secure the connecting plates or their extensions to the column or to the wall of the building.

As will be seen, my floor construction does not need any horizontal beams to carry the load and transfer it to the columns or walls of the building. All the loads on the floor will be directly transferred by this system of reinforcement to the columns or the walls.

Another advantage of my system against other floor constructions as used at present is that the upper and lower surfaces of the floor are absolutely parallel to each other the building of the the concrete is greatly facilitated be-cut to any special forms for shapes.

As the horizontal load beams are eliminated, the costs of erection are greatly reduced, at the same time the floor will be much lighter than heretofore and the columns also can be built cheaper and lighter than with the present systems.

The reinforcing rods everywhere in the floor form such a reinforcing triangde that any load at any point of the floor will always be distributed on all the four columns limiting the field in question. All the rods of the reinforcing system are stressed for tension only.

The columns of the building may be distributed in number.

any suitable system, form and This system of reenforced concrete floor can be used with stone or brick buildings as wall as with concrete buildings. My floor construction at. the same time is absolutely fire and water proof.

In case temporary horizontal beams are used while theerection work is being done, said beams do not carry any load afterwards, can be of light and low dimensionsand can crete.
