BUILDING STRUCTURE Application filed December 20, 1929.

This invention, generally stated, relates to a building structure, particularly of the ceiling type, and has for its leading object to make use of existing supporting conditions as I find them in supporting the ceiling slabs from a common carrier.

A further object of the present invention resides in the provision of the m'ode of building construction in which I irst erect a scaffold beneath the ceiling to be suspended and make use of such beams, irons, and other supports as may be present above the ceiling to be formed, and thereafter support the ceiling slabs from a common support.

It is a further object of the present invention to complete the slab structure upon the underside of the ceiling to accept the finishing plaster.

Other and further objects of the present invention reside in the provision of general details of construction, and in the arrangement, connection, and combination of parts for attaining the results sought by the foregoing objects in an expeditious and inexpensive manner and at relatively little cost.

A. still further object of the present invention resides in providing a ceiling structure which may be readily erected by unskilled labor.

The invention consists of the novel construction hereinafter described and `finally 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. 1 is a cross sectional view of the construction showing as much of the details as possible. v

Fig. 2 is a sectional View taken on line 2 2 of Fig. 1.

Fig. 3 is ai view in detail perspective of one of the hooks that fit over the L-irons.

Fig. 4 is a detail sectional view on the line 4 4 of Fig. 1.

Fig. 5 is an enlarged sectional view taken on the line 5-5vof Fig. 1.

Fig. 6 is an enlarged sectional View on the line 6--6 of Fig. 1.

design of which is immaterial.

Serial No. l15,520.

Fig. 7 is an enlarged sectional view taken on the line 7-7 of Fig. 1.

Fig. S represents a detail sectional view showing one of the slabs or blocks and the tie wire wrapped around the tit of an L-beam.

Fig. 9 represents a cross sectional view of a modified form of construction showing the hook positioned to the reinforcement in the block.

For the purpose of illustrating my invention I have shown in the accompanying drawings two 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 to the drawings, and with more especial relation to Fig.` 1, the reference numeral 10 designates the upper building structure as one may find it in a. building, and usually is of concrete, reinforced at 11. Embedded within the floor structure 10 are usually found spaced supports as beams, which may be I-beams 12, channels 13 or the like. The supports are suspended from the floor structure 10. In erecting my ceiling I first build a scaffold beneath the upper concrete 10 and then suspend the same from the support 13 so that I am always enabled to work from beneath the slabs, the advantages of which are obvious.

I either may bolt or attach in some manner as at 16 to the support 13 common carriers 17, which may be metal straps, the general The reference numeral 15 designates a precast ceiling slab or block of cementitious material as embedded in one end of a horizontally apertured flat plate 18. The slab 15 is also provided with a U-shaped reinforce 19 the legs of which are connected by cross piece 20, all of these parts being embedded in the slab or block. Each end of each block or slab is slitted or slotted at 21 to provide longitudinally extending spaced lugs 22. Op-

posite each space as formed by the lugs 22 are slots 28, see Fig. 2. In making an attachment of a slab for ceiling purposes, there is left at each end of a slab an opening arranged upon an angle, which is later filled in with cement or gypsum.

In Fig. 8 I have shown in perspective a hook having a pendant portion 25, a horizontal portion 26, these parts being preferably stamped from sheet metal. The toe of the hook-like part 24 engages within the space between a pair of slab lugs, see Fig. 6. In the connection the hook-like part of pendant part 25 engages over the upper edge of a rail 30, see Figs. G and 7. In making fast a connection of slab or ceiling precast block I make use of tie wires 31, see Fig. 7. Depending from the fioor 10, see Fig. 5, is a channel 32 rivetted to which is a rail 30. Each rail 30 is provided with a vertical lug 35 which in practice abuts against an end slab wall, see Fig. G, it being understood that the space between adjacent slabs is filled from below. In the connection I make use of wires 31 which I cause to engage the partI 23 of the cross piece in a ceiling slab.

In Fig. 9 I have shown a modified form of connection in which instead of using wires a hook 37 is provided. The strap engages over the part 30 of the slab reinforcement.

By the above arrangement and construction of parts I am enabled to erect a building structure in a much quicker, cheaper, and more efncient manner, and without the necessity of skilled labor.

In the event that the I-beams 12 are spaced too far apart I make use of the attachment shown at the left hand end of Fig. 1 and comprise a pair of opposed members 40 and 41 which engage around the lower i'ail of an I-beam 12. The members 40 and 41 may be bolted together as shown in Fig. 1.

Vhat is claimed is:

1. In a building structure, a floor of suitable material having depending therefrom in fixed position ceiling slab supports, a common carrier suspended from said supports, a series of precast ceiling slabs having slotted ends, said slabs being arranged end to end beneath the floor structure, there being a space between adjacent ends of said slabs, a metal plate embedded in each of said slabs, metal bars arranged longitudinally of said slabs, said metal bars being connected with said plate and connected at oneend across said slots.
