FLOOR AND CEILING CONSTRUCTION.
SPECIFICATION forming part of Letters Patent No. 729,799, dated .T une 2, 1903.
Application filed March 20, 1902. ASerial No. 99,232. (No model.)
To a/ZZ whom t may concern:
Be it known that I, JACOB Sonnnrwinsnn, a citizen of the United States, and a resident of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Floor and Ceiling Constructions, of which the following is a speciiication.
My invention relates particularly to fireproof construction adapted to be supported by the joists or I-beams of the building and upon which the doors are laid and the oeil.- ings hung. Its objects are, among others, to provide a strong, light, and durable construction of this character of a simple and inexpensive structure, the parts of which may be made and assembled with 'a comparatively small amount of manual labor.
It consists of the combination of parts and arrangement of details hereinafter described and claimed, and illustrated in the accompanying drawings referred to herein.
In the said drawings, Figure 1 is a vertical section of a construction embodying my iin-.-
provements partly completed, the same being taken on a line at right angles to the I- beams. Fig. 2 is a like View of a modification, and Fig. 3 is a View of the same completed. Fig. a is a detail showing the end of one of the cross-pieces B and parts secured thereto as shown in Fig. 1.
The cross-pieces BA are composed of sheet metal folded and having a core C extending through the same or part way therethrough, and preferably secured by rivets or the like passing through the said strip and core. The
ends B' of the cross-pieces thus formed rest on the lower fianges of the I-beams and have portions of the sheet metal B2 turned at right angles to the main body, so that they will rest upon the said flanges and prevent the cross-piece from being tilted. The lower edges B3 of the cross-pieces are also turned at right angles thereto and form a support for the lath, blocks, or other material used in constructing the ceiling. It will be seen that with this construction the flanges or turned portions B3 extend beneath the I- beams, thus strengthening the blocks or lath passing thereunder. At intervals running parallel with the I-beauis are strips or bars D, which act as separators for the cross-pieces and also form a support for the lath, which lnay be placed thereon,so that its lower edges will rest upon the flanges B3. y The core C at the ends of the cross-piece is preferably 1nor tised in a manner similar to the said cross pieces; `butin some forms of my construction this form of the core may be dispensed with or the core may be entirely omitted, as shown in Fig. 3. Where blocks or the like are used, they may be separated and supported by T- bars G, running parallel with the I-beams and resting upon the lower flanges of the cross-pieces B. It will beseen that in this construction the lath, blocks, or other material used for forming the ceiling may be run underneath the I-beams without having a joint at this point. The construction enabling the lower flanges of the cross-pieces to extend beneath the I-bealns in connection with the continuous lath or block forms a strong and serviceable structure and dispenses with the weakness which is found in many constructions wherein a joint occurs at this point.
In filling in the space between the I-beams I use a dry mixture of sawdust, sifted ashes, or some other suitablesubstance of a like character, as shown in Fig. 3, and designated by the letter I. This substance is formed so as to present a curved upper surface with -the apex in the center, and the concrete I' 4is placed upon the arch thus formed, filling in the entire remaining space. As the concrete is applied While wet, the drippings therefrom, which in constructions not provided with some means for retaining the same are wasted, will percolate through the dry filling I and serveto unite the upper portion thereof with the concrete. j
What l claim is-,
l. The combination with I`beams of a crosspiece composed of folded metal, a-portion of each thickness turned outwardly at an angle to the body thereof and resting upon the L beams at a point above the'lower edge of said cross-piece and iianges on the lower edge of y said crosspiece, a core within the fold of said cross-piece and a mortise in the end of the core adaptedv to receive the flange of the beam.
2. The combination with I-beams of a crosspiece composed ot' folded metal, a portion of each thickness turned outwardly at an angle to the body thereof and resting upon the I- beams at a point above the lower edge of said cross-piece and flanges on the lower edge of said cross-piece formed by turning;r outwardly the lower portion of the metal at an angle to the body, a core within the said cross-piece extending downwardly to the point where the lower flanges are turned.
3. The combination with I-beams of crosspieces com posed of folded metal supported by the said I-beains at their ends, portions of said cross-pieces extending below said I-beams,V
supported by said beams, inortises in the endsV of said cross-piece adapted to receive the flanges of the beams and a core within said cross-piece provided with mortises at its ends corresponding tothat of the cross-piece.
5. The combination with I-beamsofa crosspiece, flanges at the ends of said cross-piece formed by turning a thickness of the metal composingr the cross-piece outwardly at an angle. thereto, said flanges resting on the I- beams, the portion of said cross-piece between the portions which rest upon the I- beams extending below said I-beams, and flanges on the lower edge of said intermediate portion formed by turning outwardly the lower edges of the metal composing the crosspiece, a core within said cross-piece, a portion of which extends below the beam.
G. The combination with I-beams ofa'crosspiece composed ot' a single piece of material, flanges at the ends of said cross-piece formed by turning a thickness of the metal composing the cross-piece outwardly at an angle thereto, said flanges resting on the I-beams, the-portion of said cross-piece between the portions which rest upon the I-beams extending below said I-beams, and flanges on the lower edge of said intermediate portion, formed by turning outwardly the lower edges of the metal composing the cross-piece, extending underneath said I-beams.
7. The combination with I-beams of blocks or slabs supported by the lower flanges thereof and extending from beam to beam, a filling of loose material supported by said blocks between the beams and having a convex upper surface with its highest point near the center of the space between the beams, and concrete on said lilling extending from beam to beam and having its lowest portions near the beams.
8. The combination with I-beams of, crosspieces supported upon thelower flanges thereof', a ceiling construction closing the space between the beams and extending beneath the same supported by said cross-pieces, a filling of loose material upon said ceiling construction in which said cross-pieces are einbedded and concrete upon' the said filling, the upper portions of said filling being mixed with the portion of the concrete.
9. The combinationl of I beams, crosspieces supported by the lower flanges thereof, a ceiling construction closing the space between the beams comprising bars supported by the cross-pieces and connecting the same, loose material upon the said ceiling construction between the beams and concrete upon the said loose material.
Witness my hand this 12th day of March,
1902, at the city of New York, county and State of New York.
