REINFORCED-CONCRETE FLOOR-SLAB.
Specification of Letters Patent.
Application filed June 25, 1908.
Patented Nov. 22, 1910. Serial No. 440,212.
To all whom it may concern:
Be it known that I, JOHN A. Jones, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Reinforced- Concrete Floor-Slabs, of which the following is a specification.
The object of m invention. is a means by which a concrete 001' may be formed without using a temporary framing. This object is attained by the means described in the specification and illustrated in the accompanying drawings, in which,
Figure l is a perspective view of a floor slab embodying my invention. Fig. 2 is a sectional view thereof taken upon line 22 of Fig. 1. Fig. 3 is a longitudinal sectional view taken upon line 33 of Fig. 1. Fig. 4 is a longitudinal sectional view taken upon line 4-4 of Fig. 1. Fig. 5 is a perspective View of a part of a girder and the ends of two floor-slabs and the means of connecting them.
The slab consists of two longitudinal metal bars, A, embedded in concrete, B. The concrete is molded with an enlarged central longitudinal bore, 6, and with a groove, 1), upon one edge and a corresponding tongue, b upon the opposite edge. Bars, A, are situated upon opposite sides of the bore, 6. These bars are formed from expanded metal such as described in United States Letters Patent No. 848,105, granted to me upon March 26th, 1907. The ends of the bars project beyond the ends of the floor slabs, and are provided with key-seats, a, a.
In the formation of a floor from the slabs embodying my inventlon, the ends of the slabs are rested upon girders, C, with the key-seats, a, in the bars of one slab registering with the key-seats, a, in the bars of the hollow concrete body, provided on one side with a longitudinally extending groove and upon the opposite side with a longitudinally extending tongue, and two reinforced bars located upon opposite sides of the hollow space embedded in the concrete and extending beyond the body at each end and provided with key seats and a key to secure the floor slab to the next adjacent floor slab located in alinement therewith.
2. A floor slab consisting of a rectangular concrete body and two flat reinforcing bars with expanded ends embedded in the conorete of said body, said bars having their ends rojecting beyond the floor slab and provi ed with key seats, and a key to secure the floor slab to the next adjacent floor slab located in alinement therewith.
3. A floor slab comprising a hollow rectangular concrete body, provided on each side with a longitudinally extending tongue, and on the other with a correspondingly located longitudinally extending groove, flat bars embedded edgewise in said body upon each side of the hollow space, said bars having their ends projecting beyond the slab and provided with key seats, and a key to secure the floor slab to the next adjacent floor slab in alinement therewith.
