Patented Oct. 22, 1929 UNITED STATES PATENT OFFICE WILLIAM M GOLDSMITH, OF CINCINNATI, OHIO, ASSIGNOR TO THE GOLDSMITH METAL LATH COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO CEILING ELEMENTS FOR CONCRETE FLOOR CONSTRUCTION Application filed August 4, 1926. Serial No. 127,149.
This invention relates to concrete floor structures in which arched metal tiles and strips of metal lath are employed for the purpose of forming a concrete floor beams and a ceiling structure for the floor below at one portion, and has for an object the provision of means whereby to retain the said elements in a proper relation throughout the construction of the floor.
Another object is to provide a metal lath structure for receiving and positioning the metal tiles or domes which will preclude any spreading or displacement of the tiles when said tiles are under the pressure of the weight of wet concrete.
These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:
Fig. 1 is a fragmental perspective View of a floor under construction and having embodied therein devices of my invention.
Fig. 2 is a perspective View of a metal lath of my invention.
Fig. 3 is a cross sectional View on line 3-3 of Fig. 1.
In constructing floors embodying my invention a series of metal laths 6 each having upturned opposite ends 7 each aligned to form a continuous surface and having their opposite ends supported upon soflits 8. The sofiits S are supported on shoring members 9. In constructing floors according to this invention, the use of the usual temporary flooring is eliminated, the metal laths being placed side by side in rows to span the spaces between the soil its 8. Metal tiles or domes 10 are positioned upon the row-s of tiles with the lower edges 11 of said tiles positioned against the inner faces of upturned ends 7 of the laths, thereby aligning .the tiles without further effort and retaining the ends thereof against displacement. The adjacent ends of adjacent rows of laths 6 and tiles 10 used therewith form troughs in which suitable reinforcing rods (not shown) may be placed and into which troughs concrete enters when the floor is poured for forming uniform rectilinear beams 12. As will be noted in Fig. 3, the concrete of the beam looks the upturned ends 7 of the laths 6 in said beams so that when the concrete sets and the temporary support structure is removed a plane ceiling surface remains. A plaster finish 13 may thenbe applied over the exposed bottom faces 14 of the beams and the bottom faces of the laths for producing a finished ceiling.
The lath 6 comprises a rectangular sheet of metal having spaced longitudinal ribs 15 formed therein and between which ribs the metal is perforated. The metal is not removed from the perforations 16 but is upwardly struck around the saidperforations to form flanges 17. In forming the ends of the laths 6 the ribs 15 are flattened adjacent each end to form straight plane bottoms 18 for parallel troughs 19 along the ends of the tiles. The upturned ends 7 form the outer walls of the troughs while the substantially vertical ends 20 of the ribs form the inner wall thereof. As previously explained, the edges 11 of the side walls of the tiles or domes 10 are seated and aligned in the troughs 19. In order to provide a substantial positioning means for both sides of the side walls of the tiles 10 there are provided lugs 21 at each end of each rib 15. The lugs 21 are struck from the top faces of the ribs and extend upright from the top of said edges 22 of the ribs 15. By reference to Fig. 3 it will be apparent that the combined operative height of end walls 20 of the ribs and the outermost perpendicular edges 23 of lugs 21 is substantially the same as that of the upturnet ends 7. In this manner the result attained in supporting and positioning the side walls of the tiles is had without necessitating a special type of metal lath for the purpose, and at the same time a great saving of metal is effected. It will be observed that the lugs 21, by reason of their position at the edges of ribs 15, are in reality a continuation of the side walls of the ribs and are consequently of greater strength and effectively resist any direct pressure of the tiles and concrete. The effective height from the bottom of the troughs to the top of lugs 21 precludes any possibility of the side walls of the tiles creeping upwardly under the pressure of wet concrete, so that there is eliminated an possibility of displacement of the tile walls to ward one another.
I claim:
1. As a new article of manufacture, a metal lath having upturned ends, longitudinal ribs which are closedat the ends of the lathe and are' fiattened adjacent to theupturned ends to provide transverse grooves, .andlugs struck from the body of theribs adjacent the ends" thereof, said lugs extending in a plane with certain walls of the ribs.
2. As a new articlezof manufacture, a metal lath having longitudinal ribs extending upwardly from one face thereof, upturned ends on the laths extending above the top of the ribs, and lugsystruck from the'body of the ribs and uniformly spaced from the upturned ends, the top edges of the lugs extending sub stantially above the tops ofthe ribs.
3. As a new article of manufacture, a metal lath, upturned ends 0n-said-1ath and upturned longitudinally disposed -lugs struck from the body ofthe lath and having their outermost edges spaced inwardly of the upturned ends, theends andthe lugs forming positionin and-"retaining'mean's of substantially unifhrm height providing-support on opposite sides ofthewalls of metal tiles and providing: a relativelyshallow plaster receiving recess intermediate said supporting means.
4. -As anew article of manufacture a metal lath having upturned ends; reinforcing'ribs for the lath serving asrelatively :low abutments spaced interior'ly of the upturned ends, and lugs struck upwardlyfrom said ribs to increase the effective height of the abutments.
I 5. In a deviceof the class described ametal vlath having end fianges,-reinforcing ribsfor the lath and-spaced from the flanges to provide abutments relatively lower than said flanges and means't-o increase the effective height of said abutments.
In testimony whereof, I have hereunto subscribed myname this 2nd dayof August,
WILLIAM GOLDSMITH.
