El ,@2l,2'fitl. Specification of Letters Patent.
Application filed October 12, 19117 K To all whom it may concern I Be it known that I, TIARVEY H. HICKMAN, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Tmprovement in Spacing and Supporting Deof which the following is a specification. u
This invention relates to metallic reinforces for concrete constructions and has for its principal objects to produce a simple and etliient spacing and supporting device for the bars or rods used in reinforced concrete floor, ceiling and beam construct-ions, to produce a spacing and supporting device which can be used interchangeably with bars or rods of various cross sections, such as square, round, or bars whose contours are approximately square or round, 82c, and to J attain certain advantages will hereinafter more fully appear.
The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.
In the accouupanying drawing which forms pait oi this specification and wherein like symbols refer to like parts wherever they occur,-ligure l is a side elevation of a spacing and supporting device constructed 111 accordance with my invention; Fig. 2 is atop plan view showing fragments of two reinforcing bars of square section with the spacing and supportingdevice applied ther to; Fig. 3 is a section on the line of Fig. Fig. l is a view similar to l ig. 3 showing the device applied to a bar of round section and the supporting legs of the device being modified slightly.
The device shown in the drawings con1- prises a member 1 which 'n'ehrrably made from a piece of wire of high elastic limit. I The end portions of the wire are bent. as at 2, and looped back or rebent. as at 3, to form supporting legs adapted to r on the cenx tcring or false work as to position the re intorcing' bars or rods vertically. The porj tious 3 are cxteiuled up above the body or l connecting pmtion l, as at i, and then bent v on a curve outwardly, as at b; thence in a straight line at an inclination toward the body or connecting portion 1, as at From the portion 6 the directionv changes slightly, at 7. for a short distance. and then the wire is turned away from the body or connecting portion 1, as at 8. The portions of l I the wire thus looped ured to properly positiouthe ba or hooked are adapted to receive and retain the reintorciuo bars or rods. The shoulders formed by the po tions t serve as dblltlllQlllS for the sides or the respective bars in cases where bars of square section are used. as shown in Fi. J and "l.
The distance between the shoulders for :1. given job. That is, the desired distance be tween the i'eintolring bars in the structure being determined, the clips or spacing and supporting devices are made accordiiug'ly. Normally, the distance across the mouth. of the hook less than the thickness of the bar to which it is adapted. so that in applying the device the hook has to be sprung; the resiliency ot' the hook being depended upon to retain the bar in place.
v V The portion o constitutes a flared hp so that the bar may be easily moved into the hook.
in Figs. as being provided with transverse ribs 10 on all four of faces. shown, the bottom of the bar rests liatwise on the body or conmeeting portion 1, while its outer side abuts against the shoulders. The portion '7 of the hook bears upon the'top oi the bar near the .inner' corner. Thus the bar is firmly held against turning accidentally.
In Fig. lthe device is shown as applied to a bar oi round section. That is, a bar whose body 11 is of general round section. H is provided with longitudinal ribs fti on oppo'sitc sides and transverse 13 similar to" the ribs 10 ot the square ha in this case, the longitudinal ribs 12 a TL t in a. horimutal plane and one of Sdlt-l .ihs rests in. the
curved portion iiuiued' V ately above the shoulder l. the body portion of tho bar being clamped between the. body or conncctiugi portion 1 and the incl'h-ie d hook portion G or" the spacing and supporting device which eug'ap'es the bar some distance inwardly from a line cxtei'iding vertically through the center.
. u -l The hooks or bar-receiving portions oi the respective spacing vices may be made to s the same device will a certain size and a and supporting deuch dimensions that round bar of a certain size but different from the square. For example, the device may be made for a one inch'square bar and an inch one eighth round bar of the two types shown. practice each in the drawing. That is, in
and 3, the square bar 9 is shown lit both a square bar of it is easily held side of the square bar while the inch and one-eighth bar ll measures approximately one and seven onehundredths in short diameter through the body, one and t\vent ,"-ni1'1c one-hundredths in long diameter through the ribs 12, and said ribs are e; wide,
stantially the same as that of a plain circular bar of one and one-eighth inches in diameter.
As above set forth, the shoulder 4 positions the square bar, and as the bar rests flat upon the connecting portion or body 1, against turning accidentally. However, some special provision must be made to hold the round bar against turning. This is accomplished by curving the hook portion 5 immediately above the shoulder 4 on a radius considerably Sllfil le than that of the face of the rib 12, so Unit said hook portion 5 contacts with both the upper and lower corners of the rib; and as the portion 6 of the hook contacts with the bar a considerable distance inwardly from a line extending vertically through the center of the bar, this contact between the hook portion 5 and rib, as well as between the body of the bar and portion 1 of the spacing and supporting device, is mamtaincd. Hence, there is a four point contact which is effective to hold the bar against turning.
It is noted, that in Figs. 1 and 2, the supporting legs of, the device are outward while in Fig. 4 they are substantially perpendicular to the body or connect ing portion 1. The difference inposition is merely incidental and due to difi'erences in the shape of the forming and bending dies used in manufacturing the devices.
In practice. the device may be used to spare a pair of bars constituting reinforcing units for a beam, or three or more bars may be connected by using a series of the devices. That is, in a floor, ceiling or slab structure,'wherc the reinforcing bars or rods have to be spaced equidistantly, the devices are applied respectively to each adjoining bars in a straight line throughout pair of or, if desired,
the width of the structure the devices maybe staggered with respect to each other. So, too, the devices may be made of different lengths where there is a desired variation in the spacing of the bars, as is obvious. 4
