' Z '0 all whom it may concern:
Be it known that I, JULIAN O. ELLINoEn, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Unit-Bars for Concrete Construction, of which the following is a specification.
This invention relates to frames for reinforcing concrete and like plastic materials and it has for its object the provision of an effective concrete-reinforcing frame which at the same time may be economically produced.
In the accompanying drawings there are shown several embodiments of the present invention, and those several embodiments are contemplated to be within the spirit and scope of the invention as defined by the subjoined claims.
' In said drawings :Figure 1 is a plan view or side elevation of a very desirable embodiment of the present invention. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a similar section showing a slightly changed form of loop or strap. Fig. fl also is a similar section, but shows a further slightly changed form of loop or strap. Fig. 5 is a similar section illustrating a different relative arrangement of longitudinal members and straps. Fig. 6 is a similar section illustrating another arrangement of longitudinal members and straps. Fig. 7 is an elevation. or plan View exemplifying a further slightly changed relative arrangement of the elements. Fig. 8 is a view, in a plane at right angles to all of the preceding views,'illustrating a changed construction of welding projections, with some of the straps broken off to show the Welding projections. Fig. 9 is a perspective View of a bar and a part of a strap exemplifying a further embodiment of the present invention. I Similar characters of reference denote corresponding parts in the several views.
Referring to Figs. 1 and 2, which show a most desirable embodiment of the present invention, it will be noted that the frame comprises a longitudinal member, 20 and other longitudinal members 21 and 22, the
latter members being arranged in an endwise relation but with a space between their confronting ends and being spaced from and substantially parallel withthe longitudmal member 20 and projecting outward beyond the ends of the latter. Each of these longitudinal-members has one of its surfaces formed with a plurality of spaced longitudinal pro ections, those of the member 20 be ng marked 20 those of the member 21 being marked 21 and those of the member 22 being marked 22*. The members 21 and 22 are connected to the member 20 by loops or straps 25 which have side members arranged on opposite sides of the longitudinal member and end members 25 and 25", the latter extendmg at an angle with said side members and being arranged between the same and forming elements which are integrally united, by being electrically welded, to the longitudinal members 20 and 21, or 20 and 22, at the places defined by the projections hereinbefore referred to.
In the particular exemplification of the invention shown in Figs. 1 and 2, the members 20 and 21 and 20 and 22 are relatively so disposed that their projections are on the opposed surfaces of the parallel spaced members, and the projections extend coritinuously throughout the lengths-of their. respective members. The loops or straps 25, moreover, in this particular exemplification of the invention are endless and formed of round rods. With this relative disposition of the parts the loops or straps extend around the longitudinal members and are weldably united to the opposed faces of the latter. The parallel longitudinal members are thus connected to each other by endless straps or loops having members arranged on opposite sides of the frame and integrally united to the outer or opposed surfaces of the longitudinal members. The bars, however, may be relatively so arranged that the straps or loops will be united to confronting surfaces thereof as shown in Fig. 5 or they may be so disposed that the union of the loops or straps will be with corresponding surfaces of the bars, as exemplified by Fig. 6. Again, the straps need not be endless. As shown in Figs. 3' and 5, the straps, which are marked 125 in said figures may be bent into loop form with their ends unsecured to each having bent ends 225 welded to the longitudinal members. Moreover, any of these forms of straps may be made of flat metal instead of round metal. This is exemplified in 7 and 8, in which the straps are marked The longitudinal members, furthermore, may be provided with separated welding projections instead of continuous welding projections. Fig. 8 exemplifies this, in a. form of bar marked 320, having welding projections, 320 which are separated. from each other both longitudinally and transversely of the bar, there-- by forming the bar with separated welding projections arranged in pairs. Fig. 9 excmplifics the separated projections as being arranged in single line, the projection shown in this figure being marked 420 and the bar marked 420. This figure also exemplifies the use of strap, having its ends a: uangcd side by side where they are welded to the projections, instead of being abutted, as in Figs. and 5. in Fig. 1, the straps are shown as being at right angles with or perpendicular to the longitudinal members, but they may be arranged in diagonal or inclined positions, as exemplified in Fig. 7.
It will be understood that the foregoing embodiments are merely typical examples of a concrete reinforcing frame characterized by the employment of a plurality of longitudinal members arranged in a spaced relation and connected with each other by a loop or strap having members arranged on opposite sides of the frames and between the lontudinal members and other members which are disposed at an angle to the first mentioned members and are weldably united electrically to the longitudinal members: and that other than the herein particularly illustrated embodiments of the invention may be made without departing from the spirit of the invention as defined by the subjoined claims. Especially will it be understood that any of the straps herein illustrated may be employed with any of the forms of longitudinal members.
it frame constructed in accordance with the present invention is very strong and durable andmay be economically produced.
Having now described the invention whati believe to be new and desire to secure by Letters Patent, is-
l. A reinforcing frame for concrete and the like comprising a plurality of spaced bars having welding projections and straps which connect said bars together, each of said straps comprising parts which are arranged on opposite sides of the frame and between said bars and other parts disposed between the first mentioned parts and Weldably united to the bars at places defined by said projections.
