CEILING coNsrRUc'rIoN.

Application filed May 5; 1927'. Serial o. 188,958.

The present invention relates to an improved ceiling stru cture such as is used in concrete construction work for suspension of metal lathing. r I

Briefly, the invention has reference to a soiiit form for pouring of a concrete joist construction which, in the present instance, em'

bodies an especially constructed metal'reinforcing means, a part of which forms a longitudinal stringer and suspension means for the backing rod and metal lathing which is tied thereto and suspended therefrom.

The principal feature is a novel stringer which is in the form of an insert plate in the form and which includesangularly-disposed arms forming chairs for additional reinforcing members, together with depending sus-- pension ears for thesealing structure.

A further feature of importance is an expansion tension hanger permitting the metal lathing to be suspended at the desired elevation from the concrete joists.

The particular physical features in the improved embodiment together with the ad vantages derived from their use, will become more readily apparent from the following description and drawings.

In the drawings V Figure 1 is a transverse section through the form into which the fluid concrete is poured.

Fig. 2 is a fragmentary top plan view of the same.

Fig. 3 is a cross section through the com pleted concrete joist, the embedded metal reinforcing means and a fragmentary portion of the metal lathing and suspension means.

Fig. 4 is an enlarged fragmentary detail perspective view of the improved reinforcing stringer and ceiling suspension inserts.

Fig. 5 is a detail perspective view of one of the extension hangers.

Fig. 6 I is a view showing the hanger in place.

In the drawings, the reference character 7 designates generally the joist soflit form such as is used in form work for concrete joist construction. This includes the wooden soflit joist 8 located between the bottom portions of upstanding metal confining walls 9.

If desired, nails 10 may be driven into the longitudinal edges of the joist to provide stops for the lower ends of the walls 9.' Located within this form is the novel metal insert and reinforcing device generally designated by the reference character 11. -This device as better shown in Fig. 4, comprises a strip 12 of an appropriate gage metal which is adapted to be inserted into the form in the manner shown in perpendicular position. 3

At longitudinally spaced points',-arms 13 are struck out to provide elongated openings 14 on the bottom edge.- These are preferably bent outwardly at right angles and are formed instaggered relation and constitute what may be convenlently designatedas chairs providing seats for vthe reinforcing rods 15 and. 16

respectively. Incidentally, therod '15 is rectangular cross section, while. they rod- 1-6is of cylindrical cross section.

Inaddition, this device is provided with depending suspension ears 17 which are located at equi-distant points, each one being of taperedconfiguration being provided in its bottom edge-with a notch 18 and adjacent its top witha tie wire hole 19. p I

By directing attention to Fig. 3, it will be seen that the referencecharacter 20 designates the completed concrete joist with the rein forcing insert and rod embedded therein. In this connection, it might be. stated that when this device 11 is set in position in form, the ears 17 is driven down into the wooden joist 8 or if desired, the joist may be provided withsockets of these. I/Vhen the product is finished, the ear 1? extends or projects be- I 23. The wire is passed through openings in' the ceiling material and through the afore said holes 19. This obviously maintains the parts in assembled relation firmly.

a In some instances, it is desired to suspend the ceiling structure further down from the concrete joist, and this is preferably done by employing extension hangers, one of which is shown in Fig. 5, and designated by the reference character 24:. The hangercomprises asmall metal straphaving a hook 25 at its upper end'and having laterally bent I shoulders 26 intermediate its ends.

The intermediate portion of the shank 27 is twisted and the shank terminatesin' a bent-up rod receiving seat, which operates in the manner represented'in Fig. 6. Obviously, when this hanger is used, the hook 25 is ear 17 While the shoulders 26 come beneath placed through the hole 19 in the depending the lower end of the ear. Thus a dependable extension hanger is provided.

ture of this kind Will be readily apparent to persons skilled inthe art to which the in- 'vention relates. Therefora a more lengthy descr ption 18 thought unnecessary.

-Minor changes in shape, jsiz e,'an'd arrangeinent coming within the invention claimed Hni'a'y beresortedto if desired. j

'Haying thus described our invention, what 'lhAs new produetof manufacture, a forn insert of ,th? class described comprising a inetal str p having rod supporting arms s-truek out therefroln'at longitudinally spaced points, and disposed at right anglesto the body portion, said strip beingv formed on its lower edge with a depending apertured ceili l; s p nsio haying 1 9 in its bottom.
