orties BUILDING STRUCTURE Application November 3, 1930, Serial No. 492,899 Renewed April 6, 1933 22 Claims.

This invention, generally stated, relates toa building structure and has more especial relation to cementitious slabs forming a ceiling constructilgn as supported by a floor of concrete or the li e.

The leading object of the present invention may be said to reside in the provision of means whereby unskilled labor may more readily and eiciently erect cementitious ceiling slab-s to reduce building costs.

A further object of the present invention resides in the provision of ceiling slabs of cementitious material provided with hook-like suspension devices whereby the slabs may be quickly and easily suspended from plasterers channels.

A further object of the present invention is to provide cementitious ceiling slabs of the character stated in which the hook-like suspension elements have hinged relation with respect to the slabs, whereby the hook-like elements may be moved to inoperative position so as to be capable of assuming a horizontal, relatively flat-like position to facilitate the storage, packing, and shipping of the slabs by the manufacturer.

A still further object of the present invention is to provide a slab structure of the character stated which is entirely constructed of fire-proofing material, is sound proof, very strong and very cheap to erect, and in which metallic, hooklike suspension elements are provided for the suspension of the slabstructure from auxiliary plasterers channels as supported by main plasterers channels, which in turn are suspended from floor beams, or floor itself.

Other and further objects of the present invention reside in the provision of the general arrangement, combination, and connection of parts for attaining the results sought by the foregoing objects.

The invention consists of the novel construction hereinafter described and nally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings. forming part hereof, and in which:

Fig. l is a fragmentary View partly in longitudinal section of a ceiling construction embodying the invention;

Fig. 2 is a fragmentary View in plan of the ceiling slab shown at the extreme left hand end of Fig. 1;

Fig. 3 is a top or plan View of a ceiling slab equipped with suspension hooks differing slightly from those disclosed in Figs. 1 and2;

(ci. vz-ns) Fig. 4 is a View in side elevation of Fig. 3;

Fig. 5 is a top or plan view of a slab equipped with still another form of suspension hooks;

Fig. 6 is a View in side elevation of Fig. 5, and

Fig. 'l is a View in perspective of a channel support.

For the purpose of illustrating my invention I have shown in the accompanying drawings several forms thereof which are at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Referring now to the drawings in detail, the reference numeral I0 designates a ooring usually of concrete o-r the like, preferably reinforced as at II. A flooring of this character is usually supported by licor beams designated I2. Supported by the beams I2 are plasterers channels i3, the latter being attached to the floor beams I2 by means of hangers Ill which may be of any preferred design. The plasterers channelsl S3 in turn support auxiliary plasterers channels i5 which are arranged at right angles to the main plasterers channels I3 and are supported by means of hangers I5 which may be of any desired design. Below the auxiliary plasterers channels I5 are arranged the ceiling slabs designated I6 and which are of cementitious or other fire-proofing material. These ceiling slabs are suspended from the auxiliary plasterers channels I5 by means of hook-likemernbers of which several forms are disclosed in the drawings.

Referring now more particularly to Figs. l and 2 of the drawings, a ceiling slab I6 is provided at opposite ends with spaced removable hooks. These hooks are of metal and preferably forrned from a single piece of wire, each hook comprising an elongated, vertically disposed stem il, the lower end of which is bent at right angles to the stem to provide a foot I3, and the upper end of the stem Il is bent over horizontally at right angles to the stem and in a direction opposite to the foot I8 to provide a hook I9 for engaging over an auxiliary plasterers channel l5. The foot I8 of the hook is adapted for removable insertion in horizontally arranged tubing 2l) of metal which is embedded in each ceiling slab I6 and spaced apart, as clearly shown in Fig. 2. Each end of a slab I 6 is cut away laterally to provide a ledge 2I, the

upper surface of which is substantially flush with the tubing 28 and the marginal surfaces of which abut similar surfaces on adjacent slabs, as clearly shown in Fig. 1. In practice with a foot of the hook positioned within the tubing the hook may be moved aboutl the horizontal axis of a foot, whereby the hook may be moved from horizontal position to vertical position to engage an auxiliary plasterers channel I5. This provides what may be termed a pivotally disposed hookike suspension element which may be moved to flatwise position with respect to a ledge 2|, whereby the manufacturer may more readily pack, store, and ship the slabs I6. As clearly shown in Fig. 1, the hooks of adjacent slabs I6 are so positioned that they may engage over an auxiliary plasterers channel I5 in opposite directions.

Referring now to Figs. 3 and 4, the side walls of opposite ends of the slabs I6 are cut away to provide hook-accommodating,recesses. Each of these hooks is also formed of one piece of wire and comprises an elongated, laterally disposed portion 22 which extends entirely through a slab I5 and projects into the opposed cut-away portions 23, at which point the said portion 22 is bent at an angle to provide arms 24 terminating in hooks 25. These hooks 25 in inoperative position are accommodated by the recesses 26 of the cut-away portions 23, as clearly illustrated in Fig. 4. These hooks 25 are adapted to engage over the tops of auxiliary plasterers channels |5 in the suspension of the tiles. Thus, for packing, storage, and shipping purposes the hook-like members are moved to the position shown by full lines in Fig. 4, and for erection purposes are moved to the position shown by dotted lines in Fig. 4.

Referring now to Figs. 5 and 6, a ceiling tile I6 has embedded therein a reinforcing member usually wire, the parts 21 of which parallel the sides of a tile and the parts 2B of which parallel the end walls of a tile, the entire reinforcement constituting a generally rectangular shaped element. It is to be noted in this respect that the parts 28 of the reinforce element are arranged immediately above the slotted portions 29 with each end of a tile to reinforce a tile structure at its ends. The slots 29 are flush with the tops of the ledges 2|, see Fig. 5. These slots 29 in conjunction with the ledges 2| provide means for the removable reception `of hooks shown by dotted lines in Fig. 6. These hooks are similar in all respects to those hooks shown in Fig. l and the same reference numerals have been applied thereto. It will be understood that these hooks for packing, storage, and shipping of the slabs may be either entirely removed with respect to the slots 29, or may be positioned upon the tops of the ledges 2| to assume a fiat-wise position. It will be readily understood that in positioning the slabs the workman has simply to introduce the foot of a hook with respect to a slot 29 and thereafter move the hook about the horizontal axis of the foot portion thereof so that the stem I1 is positioned vertically, whereby the hook I9 may be caused to engage over an auxiliary plasterers channel I5.

In practice the ledges of adjacent slabs abut endwise, so that a space is present between said slabs to accommodate the stems of the hooks as shown in Figs. 1 and 6, in which case the stems to abut against the vertical cut-awayportions of the slabs, thus tending to prevent endwise or swaying movement of the slabs when-the hooks engage over the plasterers channels. In Figs. 3 and 4 the stems of the hooks abut against the cut-away vertical portions of the slabs and tend to steady the slabs both laterally and longitudinally considered in suspended position.

While the main plasterers channels I3 are shown as being supported from floor beams I2, it is to be understood that I have in mind supporting the channels directly from the flooring by means of suitable hangers when found conven ient so lto do. Also, while I may employ any convenient form of auxiliary channel hanger I prefer to use the type best seen in Fig. 7. This one piece Wire hanger I 5 is provided with a flattened cross-arm I5 so that a snug i'lt may be obtained for the channel iron I5, thereby to permit lthe ceiling slabs I6 to abut against the undersides of said channels I5 which is desirable. In using these hangers the ends are first placed over the channels |3 and then clinched over the same by means of a hammer to bring the tops of the auxiliary channels I5 close up under the bottoms of the main channels I3.
