CONCRETE FLOOR CONSTRUCTION Filed June so, 1930 2 Sheets-Sheet 2 Patented Aug. 9, 1932 UNITED STATES PATENT *oFFms MAX S. GOLDSMITH, OF CINCINNATI, OHIO, ASSIGNOR TO THE GOLDSMITH METAL LATH COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO CONCRETE FLOOR CONSTRUCTION Application filed June 30, 1930. Serial No. 464,724.

This invention relates to concrete floor constructions of the type disclosed in my Patent 1,168,627. I

An object of this invention is to provide a combined floor and ceiling structure wherein auniform plaster receiving surface is provided.

Another object is to provide means for the purpose indicated that are simple in construc- 1o tion and manufacture, and which may be readily assembled by means of unskilled labor, but which, because of its arrangement, and relation of parts, will substantially preclude error in installation by such unskilled labor.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fig. 1 is a perspective view, parts. being broken away, showing a fragment ofa floor and ceiling structure embodying the invention.

Fig. 2 is an enlarged sectional view on line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmental perspective view of a metal lath and a spacer pan, all of which form details of the invention.

Fig. 4 is a view similar to Fig. 3 and illustrates the use of expanded metal lath as distinguished from the sheet metal lath shown 111 3.

The shoring and temporary centering 11 may be of the character illustrated in the said patent to Goldsmith 1,168,627. The temporary centering 11 may comprise spaced solfits or solid decking.

The lath 12 is provided with upturned ends 13 that are disposed at substantially the center of concrete ribs or beams 14 that are tobe formed over and adj acent the assembled lath 12, spacer pans 15, and arched forms or tiles 16. The upturned ends 13 of abuttinglaths 12 are illustrated in Fig. 2' and in the preferred form of construction would be disposed at substantialy the center of the various ribs such as 14. 7 The spacer pans or members 15 are mounted upon the lath and extend from the upturned ends 13 of the lath to the downwardly extending arms or walls 17 of the arched forms or inverted U-shaped tiles 16.

Each of the spacer pans 15 comprises a body member or portion 18 along the lateral edges of whlch are provided depending flanges 19 flange 20 is a flange 21. A flange 22 extends along the'flange 21. The flanges 20, 21, and 22, provide a pocket, groove or recess 23 along one lateral edge of the pan. The grooves or channels 23 are adapted to receive and hold 7 fore follows that when a pair of laths are placed with their upturned ends in abutment, as shown 1n F 1g. 2, and the spacer members 15 and the tiles 16 are: assembled with the lath,

that a space or pocket 24 is provided between the lath and the spacer member 13 and which pocket extends substantially one-half of the provision of a similar pocket between the adjoining'lath and spacer member, provides'a structure wherein the lower face of the concrete beam or joist 14 is spaced from the lath surface to such extent that the plaster may and 20. Attached to and extending along the v width of the beam or joist 14, and that the be applied over a uniform lath face and may V be spaced from and below the concrete beam at variable distances, depending upon the depth of the pockets.

By varying the width of the body member 18 of the spacer pans 15, the width of the beams 14'may be modified. By way of illustration, if the beam 14 is to be substantially four inches wide, the body of the spacer members 15 would be approximately two inches, whereby the arrangement of a pair of such spacer members in the relationship shown in Fig. 2 would provide an over all four inch width for the resultant beam '14 formed over such spacer members. Although there may be instances in which pans orthe spacer member such as 18, of dissimilar width might be used tov advantage, the pans would ordinarily would not be obligedto pay anyattention to the order in which said assembled lath, spacer 1 members and archedjorms, are disposed over the temporary flooring or centering 11.

After the concrete is poured over the assembled structure, the concrete beams formed between the arched forms lock the upturned ends of the lath and hold the lath, the spacing members and the arched forms. in position.

Fig. 4: discloses the use of so-called expanded metal lath l0 in lieu of the sheet metal lath 30 shown in Fig. 3. V In sheet metal lath it is common to provide ribs such as 31. If some strengthening membersshould be desired in connection with expanded metal lath such as 40, any of the various ribbed expanded metal laths may be utilized.

By reference to Fig. 3 it .will be observed that the ribs 31 are deflected downwardly as indicated at 32, when forming the upturned end 13 and that at the deflected portion 32 of the rib there is provided a recess or pocket 33 into which the lower edge ofthe flange 19 may enter. The said entry of the flange into the seat or pocket 33 may be utilized for retaining spacer members in position relative the lath, or if desired, suitable nail holes such as 34, may be provided in the body18 or some other portion of the member 15 for temporarily fixing the parts in assembled position over and upon the temporary centering. In like manner fastening means may be employed for temporarily fixing the lath relative the temporary centering. It is to be understood that any type or kind of lath that adapts itself to this invention, may be employed, and that the lath may .be reenforced or strengthened by ribs or any other means. I

After the concrete has been formed over the assembled lath, spacer members and tiles, and has set sutficiently to permit removal of the temporary centering and shoring 11 and 10 respectively, there is provided a plaster receiving surface that is uniform throughout the ceiling area formed under the concrete rib and slab structure shown herein.

Although the tiles or arched forms 16 shown herein are illustrated .as corrugated and as sheet metal, it is to be understood that the invention is not restricted to arched forms or the specific characteristics mentioned. The term tile orarched is intended to comprehend any type or kind of form that maybe positioned over the temporary centering for providing voids, air spaces or pockets in the concrete floor and ceiling that is to be formed.

Some of various forms that may be used are shown in my Patent No. 1,747,294, wherein the forms or tiles are provided with removable tops. a p

What is claimed is 1. In a concrete floor in course of construction-the combination of temporary support means, parallel rows of hollow members of different heights arranged to provide rib molds between adjacent higher members and over the shallower members, the shallower members having pockets formed along their lateral edges, and the higher members comprising side walls having their lower edges received in the pockets.

2. In a concrete floor in course of construction the combination of temporary support mea-ns, parallel rows of lath on the support means and having their lateral edges upturned and in abutment on one another, and a plurality of inverted U shape members of dilferent heights received between the upturned edges of the lath, the inverted U shape members adjacent the upturned ends of the lath being shallow relative the adjoining U shape members, whereby to provide spaced concrete ribs over the shallow members and in which ribs the upturned lath ends are embedded.

3. In a concrete floor incourse of construction the combination of temporary support means, parallel rows of lath having upturned lateral edges in abutment, parallel rows of hollow members of different heights supported on the lath between the upturned edges of the lath, the hollow members arranged to provide rib molds between adjacent higher members and the upturned lath ends extending into said rib molds, and concrete in'the rib molds covering the shallower members and securing the upturned lath ends.

'4. In a concrete floor in course of construc tion the combination of temporary support means, parallel rows of lath having upturned lateral edges in abutment, parallel rows of hollow members of diiferent heights having contiguous lateral edges and supported on the lath between the upturned lath edges,the hollow members arranged to provide rib molds between adjacent higher members and into which rib molds theupturned lath ends extend, the contiguous edges of the. higher and'shallower members having mterengagement for retaining the members in contact,

and concrete in the rib molds covering the shallower members and securing the upturned lath ends.

' '5. In a concrete floor in course of construction the combination of temporary support means, rows of lath having abutting upturned ends, hollow members on the lath and having depending walls spaced from the upturned lath ends, and hollow spacer means between the upturned lath ends and the depending walls, the upturned lath ends projecting above the spacer means, and. concrete formed over the spacer means and between the depending walls and embedding the upturned lath ends.

In testimony whereof, I have hereunto subscribed my name this 23rd day of June, 1930.

I MAX S. GOLDSMITH.
