REINFORCED CONCRETE CONSTRUCTION.

Specification of Letters Patent.

Patented Apr. 30, 1918.

Application filed October 16, mic. Serial 110 25554.

'The present invention relates to reinforced concrete constructions, and more particularly to the joinder of the blocks, sections and similar individual building elements of reinforced concrete used in the construction of walls, roofs, staircases and other parts of an edifice.

Heretofore, considerable difiiculty has frequently been experienced in fastening together the ends of the metal reinforcing members embedded in the blocks, etc., in order to connect the abutting ends of adjacent blocks, so that relatively weak joints often result, especially where the reinforcing members take the form of heavy iron bars or beams. It is to overcome this substantial defect in theordinary method of procedure that my invention has been devised, the essential feature of the invention being the construction of the reinforcements in such a way that their projecting ends can be readilv and quickl locked together with the aid 0 .simple an inexpensive devices to produce an extremely strong, permanent connection therebetween.

In the accompanying drawing:

Figure 1 is a perspective view, showing one way inwhich the ends of the members of a four-piece joint may be connected.

'Fig. 2 is a perspective view, showing a slight modification. or development of the arrangement illustrated in Fig. 1.

Fig. 3 is a perspective View showing the invention as applied to a two-piece joint.

Fig. 4 shows a modification or development of Fig. 3.

Fig. 5 shows the application of the jcnt depicted in Fig. 1 to the girders of a roof.

Fig. 6 shows the two-place joint ofFig. 3

applied to the sections of a staircase construction. j

Figs. 5 and 6 also show end views of a girder and a staircase section respectively.

Referring to Fig. 1, the invention is illustrated as a plied to a joint formed at the meeting en s of four metal bars B, though it is to be understood that the particular numberfof bars is an immaterial matter, the

bars being arranged in angular relation with respect to one another, and having their aforesaid meeting ends bent abruptly u'pward. Also, said bars are shown as of square or, rectangular section, .so that the mutually-adjacent faces of their bent ends will fit flush againsteach other. The bars are retained in position by means 0f.anap ertured or skeleton link or links, Fig. 1 showing a single link A, which fits over and closely engages the up-turned bar ends.

In Fig. 2, the meeting ends of thebars are substantially T-shaped, that is to say, said bars are provided at their said ends with vertical cross-pieces or heads, which give them the appearance specified, and. they. are engaged by upper and lower llnks A and C, through whose open central portions the terminals of the cross-pieces project and are conformablyengaged by the marginal walls of the angular openings. The confronting faces of the said cross-pieces are rounded in this form of the invention, so that an opening is produced therebetween as will be apparent upon inspection of Fig. 2, through which opening a retaining pin" orriiiet shown) is preferably inserted. to. hold the links in place. 1. a

In the constructions just described, the links A, A, are represented asldisengaged from the bar ends for clearness of illustration, although in Fig. l the link indicated in dotted lines at a in itsefl'ective or engaged POSltlQl1,'ll1 which osition it may be. retained in any suita -le manner, as for instance byclenching the corners of the rotl ends, or, as illustrated in Figs, 1 3 and l, by simply upsetting the outer corner or corners of one of said ends.

The joints depicted in Figs. 3 and 4 cmbody the same general principles as those represented in Figs. 1 and 2, with this difference that only two bars B are used instead of four, 50 that an elongated rectangular link A is employed in place of a square link. In the case of Fig. 4, however, a third har C is driven between the up-turned ends of the bars, in a direction perpendicular to the link A and to the body portion of the bars; and in such instance, the bar C may have a, wedge-shaped head and the opposed faces of the up-bcnt bar ends may be beveled or inclined, as shown.

Fig. 5 illustrates the application of the joints shown in Fi 1 and 2 to the construction of a me with concrete girders l-ton link fitting over the arranged at right angles to each other, ouch 'rder section P having one of the bars B embedded therein. These girder sections are all of the sameheight, and they meet in precisely the same way as the bars 15 in said Figs. 1 and 2. Their confronting ends are preferably cut away or beveled at an angle of about so as to permit them to closely interfit and also to provide a space or opening 0, into which plaster cement may be poured to fill the joint and the said space or openin itself, as well as the interstices between the bar ends. The spaces between the irders may filled by concrete plates, s abs or blocks, which may be laid therein in any desired manner.

In Fig. 6, there is represented a portion of one of the sides of the staircase, comprising two concrete sections P connec toglgther by means of the joint illustrated in i .3.

It i ls to be understood that the foregoing are merely examples of certain of the uses to which the improved joints may be put. Consequently, no' limitation to such uses is contemplated, nor is it intended that the invention is restricted to the precise structural details shown and described, exccptin in so far as imposed by its scope as claime I claim as m invention a .1; In a rein orced concrete construction, a plurality of separate concrete building elements arranged in angular relation, so that the ends of all of them confront a common Eoint; reinforcing bars embedded in said uilding elements and projecting outward through the confronting ends thereof, the pr 'ecting ends of said bars bcin formed wit vertical, T-shaped heads whic are arranged in abutting relation to one another; a single skeleton hnk fitting over the 11 per portions of all of said heads; a single 3 elelower portions of all of said heads, said links scrvlng to hold 1 aitlt'l heads and links on:

ments arranged in angular relation, so tint :1

the ends of all of them confront a. comm-on point; reinforcing bars embedded in sad building elements and projecting outward through the confronting ends thereof, the projecting ends of said bars bein formed with vertical, T-shaped heads whic are arranged in abutting relation to one another; a single skeleton link fitting over the h per portions of all of said heads; a single s eleton link fitting over vthe lower portions of all of said heads, said said heads in abutting relation; and a retaining member driven between said heads to lock the same to said links.

3. In a reinforced concrete construction,

a plurality of separate concrete slabs arranged to form a joint; reinforcing bars embedded in all of said slabs and proj It ing outward. through the joining: surfaces of said slabs, the projecting rods of said bars having abrupt, lateral extcnsi ms arranged in direct juxtaposition to each other; and a single link which is fitted over all of said extensions and by which they are locked together 4. in a reinforced concrete roof or floor construction, sectional. longitudinal and transverse concrete girders, having rein forcing bars embedded in their bottoms, the ends of all of said. bars projecting mitward from the joining ends of said girders and having abrupt, lateral extensions and a single link fitted over all of said extensions to lock them together.

In testimony whereof I have aiiixed my signature.
