FLOOR ANL CEILING CGNSTRUCLIEON.` Y

Application filed May 20,

This invention relates to floor and ceiling constructions for buildings of any hind or class, and the object of the invention consists `in the provision of a plurality of sheet metal strips or sheets of such width as to form ceiling panels orstrips and yalso fashioned to form the joist of a floor, said strips or sheets including the joist portions, preferably extending from one beam to another, or from one wall to another, that is 'to say, from an outer wall to a partition wall or other intimate wall; a still further object being to provide means whereby `a floor facing of any kind or class may be mounted in connection with and supporting upon the joist, and still further whereby the space between the joist and above the ceiling strips may be filled in with a suitable material, for example concrete; and a still further object being to provide means whereby the lower4 face of the ceiling strips or sheets may be fashioned to permit of the application of a ceiling facing or coveringyand with these and other objects in view the invention consists of a device of the class and for the purpose specified which is simple in construction, eflicient in use and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the fol` lowing specification, of which the accompanying drawingfor-ms a part, in which the separate parts of my improvement are designated `by suitable reference characters in each of the views, and in which:

Fig. 1 is a diagrammatic, sectional view illustrating a part of two walls with my ceiling and fioor forming construction mounted in connection therewith;

Fig. 2 is a partial section on the line 2-2 of Fig. l anden an enlarged scale, showing the ceiling partially in perspective;

Fig. 3 is a view similar toFig. 2 but showing a modification;

Fig. l is a perspective detail view of the strips or sheets shown in Figs. 1 and 2; f Fig. 5 is a perspective view of one of the strips or sheets shown in Fig 3; and,

Fig. 6 is a sectional detail View` of a part of a sheet showing another'modification.

In Fig. 1 of the drawing, I have indicated at 10 and 1l two walls of a building, both of which are inner walls, in the construction shown, and in the wall 10 is a steel beam or girder 12 and a similar beam or girder 13 is in the wall 11. In the construction of the 1926. Serial No. 110,396.

building and in forming the floor and ceil mg struct-ure in accordance with my invention, as shown in Figs. `l, 2 and el. of' the drawing, I mount upon the top of the

beams

12 and 13, metal strips or sheets 'lll which extend from one beam 12 to the other beam 13 in the manner indicated in Fig. 1 of the drawing, the ends of said strips or sheets being imbedded in the wall structure as will be apparent, and as seen in said figures, the strips or sheets 14 consist of comparatively wide ceiling forming portions 14d, at one end of which the sheet is bent backwardly upon itself as seen at 14"and then upwardly at right angles to the sheet Li as seen at 11i to form a joist member having a" flanged top 1111.` The side portion 14 of the sheet is straight, as seen in F igs. 2 and Il of the drawing, and in assembling the separate sheets in the construction of a floor and ceiling, the side portion 14 is placed upon the inwardly turned flange portion 141-, as clearly seen in Fig. 2 of the drawing, and when the separate strips have all been placed in position, it will be apparent that a f'loor and ceiling frame structure, comprising ceiling facing portions le and spaced joist portions or members 14, will result.

The flanged side portions 14.* of the sheets may form a panel o1' beamdike effect for the ceiling structure,` or suitable facings or coveringssmay be applied to give a smooth and finished effect in the manner illustrated in Fig. 3 of the drawing, and later described.

A flooring 15 of any kind or class is mounted uponthe flanged upper ends 111 of the joist portions 111C, andas illustrated in Fig. 2` of the drawing this flooring may be of concrete, tiling, boards, slabs or the like, and as shown is `also mounted upon a body 16 contained within and between the joist members lil and above the ceiling forming portions la. This body 1G may be composed of concrete or any other suitable material, it being understood that the strips or sheets employed will be of such strength as to sustain the body 16, and further to provide the necessary fioor strength, which results may be accomplished by gaging the thickness of the sheet metal employed, and further by the distance arranged between the joist inembers, 111C, and still. further by reinforcing said joist members, as seen in Fig. 6 of the drawing, by attaching angle plates 17 to one side face of the joist 14C, the angle plates 17 having top flanged portions 17 directed departing from the spirit of my invention orl vreinforced oists board flooring to the joist 14,

in oppostie directions to the flanged tops 14d of the joist 14C. It will be understood that a floor and ceiling construction may be made up of a combination of the joist structures, as seen in Figs. 2 and 6, that is to say, the i may be incorporated at intervals with the single joist, for example every other joist may be reinforced, or every third joist reinforced as the case may require.

In Figs. 3 and 5 of the drawing, I have shown a modification in the formation of the strips orsheets 14;, wherein I have substituted for the straight edge portion lile an offset edge portion llf, the offsetbeing upward tofcompensate forthe two thicknesses of metal at the flanged side portion let", whereby when the separate strips or sheets are vplaced together', a straight and flush ceiling surface is` provided, as clearly seen in Fig, 3 of the drawing. In this form of constructionl have also illustrated apertures 18 in the ceiling'forming portions 14Ta of the strips` ory sheets, whereby a ceiling surface or body 19 of any suitable material may be applied to the strips or sheets and anchored thereto, by the passage of the body or substance 19 through the apertures 18 provided,

as indicated at 20 in Fig of the drawing.

InV Fig. 3 of the drawing I have also shown another vmanner of securing, preferably a which consists in mounting wooden strips or slabs 21 upon the top flanges 14d, of the j oist and nailing or otherwise securing a board flooring 22 thereto. However, I am not necessarily limited to any specific manner ofconstructing the floor surface or attaching and supporting the same to the joist, and various changes in and modifications of lthe construction herein shown and described may be made, within the scope` of the appended claims, without sacrificing its'advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

l1. A ceiling construction for buildings `fashioned from a plurality of interlocking members adapted to extend from oneV wall toanother, said members being formed from strips of sheet metal, oneside of said strips beinfr folded upon itself to form a. project-- g flange of two thicknesses of the metal of said'strip, and a part extending substantially at right angles to one face of said strip, and a fiange at the free edge ofsaid part, said part. forming a joist member upon which the floor Vsurface is adapted to be supported.

2.
