Claims. (01.. 189-34) 5 one to the other, .at points intermediate the supporting beams.

In the construction of metal decks for floors and roofs, it is customary to use elongated metal plates having depending flanges which rest upon supporting beams or purlins. Where the depending flanges contact with the supporting beams or purlins, it is customary to provide clips which secure y attach the depending deck flanges to the flanges of the supporting beams or purlins; In view of the fact that the beams are usually spaced comparatively far apart, it is desirable that the adjoining decks be securely attached together at points intermediate the supporting beams.

An object of this invention, therefore, is to provide a building deck construction having means for locking the adjoining decks together at points intermediate of the supporting beams; also to improve building constructions in other respects hereinafter specified and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which I Fig. 1 is a perspective view of one of my improved roof decks, or

k Fig. 3 is a perspective view or one of the locking eys,

Fig. 5 is a sectional elevation similar to Fig. 4, but showing a modified form of locking key,

Fig. 6 is a sectional elevation showing the form of clip for attaching the decks to supporting beams, t v

Fig. 'l is a sectional elevation through a building deck construction at a point where the ends of the decks overlap, and

-Fig. 8 is a perspective view of one end of a modified form of deck construction.

One form of my improved metal deck shown in Fig. 1, consists of an elongated plate In, having longitudinal channel shaped ribs II which divide which extends from one end of the deck to a point somewhat less than the opposite end of the deck. The bead l2 also serves to reinforce the plate In in a longitudinal direction and makes said plates more resistant to, loads which might be placed upon them.

One longitudinal edge of the plate In is provided with a downwardly extending channel flange l3, which terminates at its lower edge in an arcuate shaped bulb channel I l which has an outwardly flaring lip l5 at the upper edge of said bulb channel. A downwardly extending flange i6 is formed along the opposite edge of 'each plate ill, the flange l6 terminating in an arcuate shaped section I! adapted to enter into and engage the inside of the bulb channel I l. The bulb channel It and section I! thus form registering locking-shoulders.

Due to the narrowing action of'the reinforcing bead l2, the decks may be telescoped together so that upon their erection on a sloping surface of a roof, they form a water shed immediately upon erection. Supporting beams or purlins l9 are positioned below the decks l0 preferably at the points where the ends of the decks telescope together. The beams [9 preferably have outstanding upper flanges 20 which engage directly with the bottoms of the bulb channels. In order to securely attach the decks to the purlin flanges 20, a clip 22 is provided on top of the flange 20, said clip having bifurcated ends 23, which are arranged to be bent around the flange 20. An upstanding flange 24 is formed on the clip 22 and is bent back upon itself to form a downstanding channel flange 25, which terminates in an arcuate section 26, said arcuate section being arranged to fit within the bulb channel [4 of the adjacent building deck.

In order to securely lock adjoining building decks together at one or more points intermediate the supporting purlins I9, I provide a locking key 28, which is composed of a flat strip of metal 29, formed into a cylinder 30 at its lower end, and

having an upstanding flange 3| in closely abutting relation to the metal, strip 29. Thetops of the strip '29 and the flange 3| are preferably in the same plane to form a shoulder 32 which may be used for hammering the locking key into position between deck flanges l3 and [6, so as to press the arcuate flange section ll tightly into locking position against the inner walls of the bulb channel H and section [1. It will be noted that the cha-nnel flange It extends through approximately 270' degrees so as to leave a substan tially open throat to permit th transverse insering the locking key It yields slightly and the metal deck flanges yield also when the locking key is being driven into locking position from above the building deck.

A prong I3 is preferably formed integral with the metal strip 29 and extends upwardly to a point substantially above the deck plate iii. In constructing a roof, it is customary to mop asphalt on the top of the metal plate Ii! and then apply a layer of insulating flber board 35 to the asphalted surface. In applying the boards", the prongs 33 are forced through the boards until the board lies flush with the upper surface of the plate It, and then the board is locked in place by bending the prongs 33 at right angles to form locking flanges 36. A stiifening bead 3| is preferably formed in the middle of the prong 33 to prevent the prong from bending over while it is being forced through the flber board. Building paper 31, shingles, or other protective layers may be then applied on the flber boards 35 by mopping on with asphalt or by other suitable means so as to make a water-shedding, heat insulating roof construction. In constructing a floor, a short piece of round solid rod 39 may be used as a locking key; and then a slab of concrete, gypsum or other cementitious materials may be poured on top of the metal deck to form a floor.- Keys similar to keys 28, but. without the prongs 33, may also be used.

If desired, a plate 42 may be made in lon lengths of 20 or 30 feet and made in comparatively narrow widths, such as 6 to 12 inches (Fig.

- 8). In sections of this nature, it will be unnecessary to use intermediate beads i2 although it may be found desirable in certain cases. Flanges i3 and ii are formed .on the edges of the plate 42 in the same way that they are used on plate l0,

said flanges having the same shape as those shown on plate ill.

I would state in conclusion that while the illustrated examples constitute practical embodiments of my invention, I do not wish to limit myself precisely to these details, since manifestly, the same may be considerably varied without departing from the spirit of the invention as deflned in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:-

2. In a metal deck, a plurality of plates arranged in a plane, each plate having an outstanding flange extending longitudinally along one edge thereof, an open channel flange of substantially open throat extending longitudinally along the opposite edge of each plate and adapted to receive the outstanding flange of an adjoining plate, and a locking key driven into position in a direction perpendicular to the plane of said plates and engaging'said flanges for locking adjoining plates together.
