Specification of Letters Patent.
Patented Sept. 9, 1919.
Application filed December 15, 1917. Serial No. 207,251. g
To all whom it may concern:
Be it known that I, WILLIAM GoLDIE, a citizen of the United States, and resident of WVilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Reinforcing-Bars for Concrete Construction; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to reinforcing bars for concrete construction, its object being to provide a strong and light bar having large exposure of surface to the concrete, and providing efiicient means for anchoring the bar in the concrete in such way that the bar reinforces and anchors the concrete, and the concrete reinforces and anchors the bar.- It comprises, generally stated, a reinforcing bar for concrete construction formed of an I-shaped bar having a central web portion and having its flanges bent toward each other so as to provide dove-tail recesses into which the concrete enters and sets in such way that the bar reinforces the concrete and the concrete reinforces the bar, as hereafter described. I
Figure 1 is a perspective view of the bar; Fig. 2 is a cross-section of the bar anchored in the concrete; and Fig. 3 is a perspective view partly broken away, illustrating the anchoring of the bar within the concrete. Fig. 4 is a perspective view of another form of bar embodying the invention.
The reinforcing bar 2 is formed of a structural shape having a central web portion 3 and having flanges 4:, 5, 6 and 7 which flanges are bent or curved toward each other, so as to form dove- tail recesses 8, 9. The preferred form of the bar is that illustrated in Figs. 1, 2 and 4:, the outer surface of the flange portion being curved preferably to form a partial cylinder, so that the outer surface of the bar forms a curved surface to which the concrete will firmly adhere. The bar may have the form of Fig. 4, however, where the outer faces'of the flanges forming the dovetail recesses are flat instead of curved. The inner surface of the web portion may be ribbed or otherwise formed to prevent longitudinal movement, but this is not necessary, and forms no part of the present invention.
When the bar is placed in the concrete, the concrete flows into the dove-tail recesses and forms a strong connection between the main body of the concrete and the bar itself, so
that when it is set the transverse strains are sustained by the bar itself, which is of a section having great rigidity and sustaining power and the flange portions are fully braced by the dove-tailed portions 10 of the concrete body, which being practically incompressible, give to the bar the full rigidity of a solid bar of the same section, and a greater rigidity because of the surrounding cement body which itself enters within the bar and holds by a dove-tailed union between the concrete body and the bar. Thus the bar has the full rigidity of an I-bar section to sustain loads, and in addition has that bar bracedby the dove-tail filling of concrete inclosed within the bar which being incompressible supports the flanges from possible deflection, and such dove-tail sections unite integrally with the surrounding concrete body, so carryin the sustaining element outwardly beyond tlie body of the bar a considerable distance into the body of the concrete which is in integral union therewith. The flanges with their curved outer faces provide for union with the concrete without marring the continuity of the contacting surfaces or breakin them up. The bar is much lighter in weig t and requires less metal than a round bar of the same main diameter, and so provides for the reinforcing of the concrete by a metal body of much less weight. The bar reinforces the concrete and the concrete reinforces the bar.
I prefer to employ the bar as illustrated in the drawing, where the web portion is in vertical position or transverse to the load strains, this giving a very strong section, and a continuous holding dove-tailed recess extending on the same plane with relation to the load strains.
What I claim as my invention is:
1. A reinforcing bar havin a vertical web and having recesses for locliing the concrete to the bar, said recesses becoming wider toward the interior of the bar. 7
2. A reinforcing bar having recesses for locking the concrete to the bar, said recesses having a central vertical web and having their greatest width adjacent the interior of the bar.
3. A reinforcing bar having a central vertical web, and having flanges projecting laterally from the top and bottom of said central web, said flanges forming recesses for locking the concrete to the bar, the dove-tail recesses extending longitudinally Wider portions of said recesses being adj aof said bar. 10 cent said central Web. In testimony whereof, I, the said \VILLIAM 4. A reinforcing bar having a central ver- GOLDIE, have hereunto set my hand. tical Web and having flanges extending lat- WILLIAM GOLDIE. erally from the top and bottom of said Web NVitnesses: 0n the arcs of a circle having the center of JOHN F. WILL, the Web as its center, said flanges forming J. R. KELLER.
