GEISLER CONCRETE STRUCTURE AND METHOD OF MAKING SAME Filed July 31, 1928 3 Sheets-Sheet 3 INValfTOR Patented Dec. 30, 1930 CHARLES R. GEISLER, OF PITTSBURGH, PENNSYLVANIA CONCRETE suinoc'runn AND nutrition on MAKING sAiun Application filed July 31,

This invention relates to fioor structures and the method of making the same, and more particularly to monolithic floors of plastic material such as concrete.

One of the objects of the invention is to provide a monolithic floor structure for balcanies, stadiums, and the like wherein an interrupted floor consisting of risers and treads is used.

Another object of the invention is to provide a monolithic fioor structure for balconies, stadiums and the like, wherein reinforcing material is used as forms for the plastic material for the risers and treads.

Another object of this invention is the design of a method of construction whereby a continuous monolithic floor structure is more rapidly and easily constructed.

Still other objects of the invention will be apparent in the detailed description herein, taken in conjunction with the drawings.

in the drawings, Fig. 1 is a perspective View, illustrating a continuous floor structure, constructed in accordance with the method; Fig. 2 is a side view in section, and Fig. 3 is a front view, in elevation, of a part of the completed floor.

Referring to the drawings, a plurality of girders 1 are disposed in spaced apart relation and slope downwardly, and may be supported in any suitable manner. Transverse supports 2, of any suitable material as wood or angle iron are secured to the girders 1. Vertical braces or joists 3, secured to the frame members or supports 2 and having frames of wood or iron 4c extending across the upper ends thereof, form the supports for the risers.

Reinforcing material or fabric 5 consisting of wire mesh and having imperforated sheet material secured to one side thereof is laid longitudinally of and suitably secured to the transverse supports 2 and 4, to completely cover the structure. The fabric 5 is shown as extending beneath and behind the supports 2 and in front of and. above the supports 4-,. This arrangement tends to cause the fabric to remain in place without additional fastening means, providing itis drawn taut.

1 28. Serial No. 296,569.

It will be, noted that the reinforcing material is used as a form for the plastic material on the treads of the structure and that the vertically disposed portions of the reinforcing material constitute one side of the forms for the risers.

Also, that the reinforcing fabric is a continuous reinforcement for the plastic material to be applied as hereinafter described.

The other side of the riser forms may be constructed of any suitable framework or form 6, being spaced apart from and temiorarily secured to the rear wall ofthe riser forms in any manner as by wires 9. An interrupted. floor 8 may be completed by pouring plastic material, such as concrete, on the tread portions of the reinforcing for-ms and in the space between the walls of the riser forms. The plastic material is preferably poured on the lower tread and then, working upwardly, in each succeeding riser and tread. If it is desirable additional reinforcing may be had by imbedding rods 7 in the plastic material. 7

After the plastic material has hardened, the form 6 may be removed, completing a monolithic fioor structure.

From the foregoing it will be seen that I provide a tread and riser structure which may be readily formed of concrete or other plastic material and wherein most of the false structure or temporary form work heretofore. deemed necessary is eliminated, and which can be quickly and accurately applied to the usual girders and'joists, the fitting of the fabric structure into position automatically producing a form for the treads and risers. g

If the wire mesh of the fabric structure be omitted, the papersheet itself can be, utilized merely as a form, but I prefer to employ also the wire mesh so that reinforcing for the concrete is automatically provided upon placing of the form sheet.

I claim: p.55

1. A monolithic floor structure having an interrupted surface consisting ofrisers and treads, comprising in combination, a pl"- rality of spacedsapart girders sloping downwardly, transverse supports secured to said ,iy'd

girders, and a reinforcing material consisting of wire mesh having a backing sheet on one side, secured to said transverse supports and bent to form treads and risers, the backing sheet of said reinforcing material constituting a form for the monolithic floor.

2. In a monolithic floor structure having a generally slo ing surface of risers and treads, the com ination of a plurality of girders in spaced-apart relation and sloping downwardly, supports disposed transversely of said girders and secured thereto, and a continuous reinforcing fabric comprising a wire mesh having a backing sheet secured to one side thereof, said reinforcing fabric constituting a continuous form and reinforcement for the said floor.

3. In a monolithic floor structure having an interrupted surface consisting of risers and treads, the combination of a plurality of girders in spaced-apart relation sloping downwardly, supports disposed transversely of said girders and secured thereto, a reinforcing fabric secured over all said trans verse supports and forming treads and risers, and removable forms disposed parallel with the said risers.

4. The method of constructing a floor consisting of risers and threads, which comprises shaping continuous reinforcing fabric to the contour of said risers and treads, the shaping being efiected upon permanent supports, placing removable forms adjacent to the riser portions in spaced relation therewith, pouring plastic material upon said reinforcing fabric and behind said removable forms, to make a continuous floor, and removing the said forms.

5. The method of constructing a floor consisting of risers and treads which comprises bending a form sheet to the shape of risers and treads, supporting the sheet in such shape, upon a framework, and applying plastic material thereto.

6. In a monolithic floor structure having an interrupted surface consisting of risers and treads, the combination of a plurality of girders in spaced-apart relation and sloping downwardly, supports disposed transversely of and projecting above said girders, a form sheet supported by said supports and having the contour of the risers and treads, and plastic material supported by said sheet and forming the exposed surface of said risers and treads.

7. The combination with a monolithic floor structure, of a support and form therefor comprising a plurality of laterally-spaced girders sloping upwardly, pairs of bars supported by and extending transversely of said girders, the bars of each pair being vertically spaced, and a continuous sheet of strip material extending beneath and behind one bar of each pair of bars and in front of and above the other bar of each pair, the sheet
