2 Claims.

This invention relates generally to the class of building construction, and has particular reference to an improved hanger for suspending from an overhead plastic structural slab, a ceiling structure of the type which embodies metallic furring and metal lath.

The hangers which have heretofore been employed entail a considerable expenditure of time and labor, due to the fact that the depending portions of the shanks were provided with a single aperture to each of which an extension strip was bolted and after which a chalk line was snapped to indicate on each extension shank the point at which an aperture was to be formed, to which the purlin strips or members were to be subsequently attached. 'I'he extension strips were then removed and numbered and apertures formed at the chalk mark. The extension strips were then again bolted to the proper depending shank.

The present invention aims for its principal object an improved hanger for the purpose set forth which is so constructed as toy materially reduce the time and labor incident to the hanging and leveling of the transverse members or purlin strips which support the furring and lathing.

More specifically, the invention resides in an improved hanger of the indicated character which includes means for insuring the proper embedment and anchorage of the upper ends of the hangers in the structural slab, and the depending portions of which are so constructed as to admit of the direct attachment thereto and the leveling of the transverse carrier members or purlin strips.

Other objects of the invention reside in the simplicity of construction of the hangers, the economy with which they may be produced and the general efficiency derived therefrom.

With the above recited and other objects in view, reference is had to the following description and accompanying drawing, in which there is exhibited one example or embodiment of the invention, while the claims define the actual scope of the same.

In the drawing:

Figure 1 is a fragmentary transverse sectional view illustrating the hangers in position in the Y plastic slab.

Figure 2 is a similar longitudinal sectional View taken approximately on the line 2-2 of Figure 1, and illustrating the hangers in section.

Referring to the drawing by characters of reference, each hanger consists of a strap like body 5 which has secured to or otherwise formed at its upper end, a transverse anchoring head 6, preferably of small channel material. In order to secure the proper embedment of the anchoring head 6 in the plastic slab A, the body 5 is formed with a suitable stop 7, which is preferably in the nature of an outstruck tongue, and which stop or tongue is designed to engage with the upper surface of the form boards B upon which the slab A is formed. The body 5 is designed to extend downwardly between two adjacent form boards B, and the lower end thereof is provided with a plurality of rows of apertures 8, the apertures of said rows being staggered so as to render available an aperture at any desired point for the reception of a bolt 9 which connects the transverse carrier members or purlin strips 10 to the hangers. In practice, after the form boards B have been erected for the formation of the plastic slab A, the hanger bodies 5 are inserted between adjacent form boards until the stops or tongues 7 engage with the upper surface of the form. After the plastic slab is formed and set, the form boards B are removed, leaving that portion of the hanger bodies 5 below the stop 7 protruding. A chalk line is then snapped to the proper level across the hanger bodies, and it will be found in practice that one of the apertures 8 of the multiplicity provided in each hanger will be in close enough proximity to the chalk line to permit of the direct attachment of the transverse members or purlin strips thereto. If it is found that too great a length of the hanger body 5 extends below the transverse members 10, the extending portion may be bent up to a non-interfering position with the furring strips C or lath D. It will be further apparent that the multiplicity of apertures 8 is suflicient to take care of any hangers which may be canted or disposed at an angle.

From the foregoing, it will thus be seen that a simple and improved ceiling structure hanger has been devised and while there has been disclosed only a single form of the invention, it is to be understood that variations and modifications which fall within the scope of the appended claims may be resorted to when desired.

What is claimed is:

1. A ceiling hanger comprising a flat, bendable metal strap, an anchoring crosshead secured to the upper end of the strap, an offset tongue projected from the body of the strap at a point below the anchoring head, and said strap at its lower portion having parallel lines of perforations, the perforations in one line having staggered relation with the perforations of the other line.

2. In a structural support adapted to be embedded in a body of concrete, a beam-like member embedded in said concrete, a hanging member having a plurality of spaced holes at one end thereof secured to said beam-like member at one end thereof, said perforated end protruding beyond the body of said concrete, said hanging member having a bent portion with the end thereof spaced flush with the face of said concrete.
