FIREPROOF CEILING AND FLOOR.
SPECIFICATION forming part of Letters Patent No. 794,438, dated July 11, 1905.
Application filed February 13, 1905. Serial No. 245,354.
1'0 0 whom it may concern.-
Be it known that I, JOHN WEBER, a citizen of the United States, residing at New York city, Manhattan,county and State of New York, have invented new and useful Improvements in Fireproof Ceilings and Floors, of which the following is aspecification.
This invention relates to an improved fireproof ceiling and floor whichis of simple construction and of superior strength and durability.
In the accompanying drawings, Figure 1 is a perspective view, partly broken away, of my improved fireproof ceiling and floor; and Fig. 2 is an enlarged end View of part of the corrugated plate and beam.
The letters A A represent the parallel I- beams of a ceiling and floor. Upon the lower flanges of these beams are supported the ends of corrugated sheet-metal plates B, which are of a length corresponding substantially to the distance between the webs of the beams. Each plate B is composed of a series of horizontal sections and intervening flaring and downwardly-opening pockets. The horizontal sections are corrugated, as at b, the corrugations extending parallel to beams A. The sides of the pockets 6 diverge from top to bottom and are also corrugated, as at 6 such corrugations being likewise parallel to beams A. At its apex each pocket 6 terminates in a narrow longitudinal groove 6 After the plates B are properly positioned cement C is filled in on top, flush substantially with the top of beams A and constituting the support for the wooden or other floor. At the bottom a coat- This coating d is forced into the grooves 6 of the horizontal plate-sections and also into the grooves 5 6 of the pockets to completely fill the latter. In this way the coating is securely anchored to the plates.
It will be seen that while the grooved pockets 5 serve as keys for effecting a secure connection between plates B and the coating (Z the grooved horizontal plate-sections constitute stiffeners for the .structure. Thus a strong, simple, and durable ceiling and floor construction is obtained.
What I claim is 1. In a fireproof ceiling and floor, flanged beams combined with sheet-metal plates supported upon the beam-flanges, each plate being composed of corrugated horizontal sections and intervening flaring pockets having corrugated sides and a grooved apex, the corrugations of the horizontal sections and pockets extending parallel to the beams, substantially as specified.
2. A fireproof ceiling and floor composed of flanged beams, intervening sheet-metal plates supported thereon and having corrugated horizontal sections and intervening corrugated pockets, the corrugations of the horizontal sections and pockets extending parallel to the beams, a cement filling above the plates, and a coating below the plates which enters the corrugations and pockets, substantially as specified.
Signed by me at New York city, Manhattan, New York, this 11th day of February, 1905.
JOHN WEBER.
