This invention relates to improvements in the construction of fireproof buildings; and

more particularly to fireproof roof decking thereof, the unitsor sections of which may be machine fabricated, ready for their application to the roof framing of the structure. It is a specific object of this invention to provide relatively long, narrow, metal roofing units or sections, comparable to the planks or boards commonly used for roof decking, and means for joining the ends of the several deck members to prevent local deflection when a load, such as a mans foot, is concentrated at the end of one of the deck members. A further object of. this invention is to provide a fireproof roof decking that may be'applied rapidly and cheaply to the roof framing of a structure, whether the framing be of metal or wood, without the use of special tools, bolts, rivets, or any of the expensive conventional attaching means.

A still further object of the invention is to provide a roof decking which presents a smooth, rigid and stiff, exterior surface that may readily be insulated and waterproofed. With these and further disclosed objects, my invention consists in the novel construction, combination and arrangement of parts hereinafter more fully described, and. illustrated in the following drawings, in which:

In the drawings, in which similar reference characters, and numerals designate corresponding parts in all figures, A represents a starting strip laid first against the parapet wall B or lined up to any position markmg one edge of the roof.

This starting strip A is formed with a double flange 1 at its uppersurface 2 which is flush, substantially, with the deck surface 7, when laid. It is formed also with a vertical flange 3 which rests against the parapet B, and with a lower horizontal flange 4 which is provided at intervals with holes 5 so that it may be nailed to wood roof purlins C or trusses; or it may be fastened by a friction spring clip D to a steel roof framing. It is formed furtherwith an upstanding flange 6 to protect the edge'of the flange 4 from becoming bent in handling.

The starting strip A provides a straight starting line for laylng the roof deck proper. A succession of deck units or sections E, as shown in Figures 1, 2 and 7, make up the roof deck. Each unit or section E consists essentially of a strip of steel formedwith a comparatively narrow exposed surface 7, and, at one edge, with an offset 8, preferably, and a vertical flange 9 with a horizontal or base flan e 10 arallel with the top surface 7. Eac unit is formed, at the op osite edge, with a double flange 11, adapted to fit into the offset 8 of the adjoinin unit E, a vertical flange 12 with a lower orizontal or base flange 13 arallel with the upper surface 7 of the deck and an upstanding vertical flange 14 to protect the flarlilge 13. The opposite sides the fr mg, as shown in igures 1, 2 and 8, mo

' is provided with two,

I posite side by driving on any suitable number of friction sprin clips D at an angle of about 45 degrees to their base flanges 13 and to the purlins or steel framing C; but holes 15 may be provided at intervals in said deck units E when it is desired to nail them to a wooden frame. All work, it is to be noted, is performed from the top, making it unnecessary to reach underneath or to use scaffolding.

- As shown in Figures 1 and 7 the butt or end joints 16 and surfaces of the deck units E are reinforced in the same plane by triangular devices F shown in Figures 1 and 3 which are located transversely beneath the surface 7 of deck units. As shown in Figures 1 and 3 the body portion or member 17 of each device is rectangular, is provided with two, triangular, vertical, upstanding flanges tends beyond the edges of the said flanges so that its projecting lip 19, at one side, extends into the double flanges 11 of butting deck units, and its projecting ledge 20, at the opposite edge, rests on the base flange 10. Each upstanding flange 18 is provided with a matching groove 21 and an edge 22 of vertical flange -18 which register with offset 8 and flange 9, respectively, of each butting unit. Every flange 18 thus supports the end joint 16 and the end surface 7 0 each unit.

A variation in the form of reinforcing device or plate, located transversely beneath the surface 7 of buttin deck units, is indicated in Figure 4.\ The ody portion or member 23 of each plate G, as shown in Figures 2 and 4, is rectangular, lies flat against the underside of the ends of butting roof deck units E, rectangular, vertical, depending flanges 24, and extends beyond the edges of the said flanges 24, so that its projecting lip 25, at one side, extends into the double flanges 11 of butting deck units, its turneddown inclined leg 26 rests at its opon the base flanges 10, and the dending flanges 24 stiffen its upper surface.- ach body member 23 thus supports an end surface 7 and the end joint 16 ofbutting deck units.

The deck roof roper, laid as described and illustrated, may waterproofed by the direct application of any of the well known roofing compounds or prepared roofings. The waterproofing material is cemented directly to the roof against heat losses, a layer of insulating material may first be cemented or otherwise fastened to the decking and the waterproofing then applied over the insulation.

I have described the principle and construction of my invention together with the distinct views which-I now consider to represent the preferred embodiment thereof; but

I do not desire to limit myself to the minor details above shown and described, as other modifications of the invention will doubtless portions 18, and exsteel decking. To insulate the P su st themselves to those skilled in the art.

at I claim is:

1. In combination, a. pluralit of sheet metal deck units having associate top walls, and reinforcements for said -top walls located transversely beneath the same and having portions at their ends interlocking with of the units below said top walls, said reinforcements being thereby'supported against the to walls to reinforce the same.
