JULIUS KAHN, OF DETROIT, MICHIGAN, ASSIGN OR TO TRUSSED CONCRETE STEEL COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHI- GAN FLOOR CONSTRUCTION.
Patented. April 30, 1907,
Application filed April 26,1906. Serial No. 313.763.
To all ZUI'LONL it Natl/[j concern:
Be it known. that I, JULIUS KAHN, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Floor Construction, of which the folowing is a specification.
This invention relates to reinforced concrete floors and ceilings, and the object of my invention is to provide a construction of this kind that can easily and cheaply be constructed, that will be strong and fire-proof, and that will have a flat surface adapted to be plastered.
My invention consists of a floor construction formed of a series of connected beams of concrete, reinforced by steel tension members, the beams being formed on corrugated and curved centers, and the centers spaced by peculiar space bars.
It further consists of a floor or ceiling formed of a series of connected beams of concrete having metal webbing embedded in the lower faces of the beams and adapted to receive and retain plaster so as to form a flat ceiling.
I attain my invention by the construction illustrated in the accompanying drawings which shows a section of floor supported at one side'by an I-beam.
The floor shown in the drawing is preferably constructed as follows. A flat false work is built up about one half inch higher than the finished height of the ceiling. On this are placed sufficient sheets of metal webbing such as expanded metal 1 to cover the entire surface. A series of space bars 2 provided with upwardly extending projections 3, in pairs, are then laid on themetal ters are then filled in forming the beams 6. The floor portion 7 is then'fllled in, all being properly packed down by ramming or rolling. The ends of the centering arches 4 may reston the lower flanges 8 of the I-beams 9 or on any other desirable support. After the concrete has set sufficiently, the false-work is removed and the metal webbing is plastered in the usual manner forming the flat ceiling 10. This construction is especially adapted for localities where ceiling and floor tiles are high in price and where corrugated arches such as shown and described can be more cheaply obtained. The number of the space bars 2, the depth of the beams 6 and the distance between their centers, as well as the character of the tension members 5 will depend greatly upon the character of the floor desired. The member 5 shown in the drawing is of the type illustrated in my former patents Nos. 743,086 and 751,921, although any other good type may be employed. The concrete of the beams will flow around. the strands of the metal Webbing and unite the beams and webbing.
Having now explained my improvements, what I claim as my invention and desire to secure by Letters Patent, is
1. In a combined concrete and metal construction, the combination of a series of parallel molds formed of corrugated sheets, space bars having upwardly extending projections to position said molds, a plastic material extending over and between said molds to form a floor and a series of parallel beamsconnected thereto, tension members molded into said beams near the bottoms of the same, metal webbing secured in the bottom faces of said beams, and plaster attached to said webbing to form a flat surface.
2. In a concrete and metal construction, the combination of a series of molds, space bars to position said molds, a plastic material extending over and between said molds to form a floor and a series of beams connected thereto, and tension members molded into said beams near the bottoms of the same.
In testimony whereof I have signed my name in the presence of two subscribing witnesses.
JULIUS KAHN.
