L. LAMPERT BAR-- SUPPORT AND SPACER Filed Feb. 21, 1951 Patented Aug. 16, 1932 nausea ATEN LYDIA LAMIPERT, OF CHICAGO, ILLINOIS, ASIGNOR 'IO UNIVERSAL FORM CLAMP CO.,
OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS i BAR SUPPORT AND srAcnn Application filed February 21, 1931. Serial No. 517,513.
The main objects of this invention are to provide an improved bar support and spacer for use in reinforcing systems of concrete construction work; to provide a bar support and spacer having an improved foot portion for temporarily supporting the device on the form; and to provide a device of this kind wherein the spacing rod and supporting chairs may be readily assembled.
An illustrative embodiment of this invention is shown in the accompanying drawing, wherein:
Figure 1 is a fragmentary perspective of an improved bar support and spacer, showing two of the improved supporting chairs secured to a spacing rod.
Fig. 2 is a side elevation of the same, showing also two reinforcing bars in section as they appear when seated on the chairs; the
dotted lines representing the reinforcing bars prior to being forced into the chair seats.
Fig. 3 is a vertical section, taken on the line 33 of Fig. 2.
Fig. 4 is a top plan of the portion shown in Fig. 3; the reinforcing bar being shown in dotted outline.
In the form shown, the reinforcing system involves the use of the. customary reinforcing bars 1 disposed horizontally in substantially parallel spaced relation above a falsework, not shown.
The improved bar support and spacer comprises a plurality of supporting chairs 2, which are spot welded or otherwise rigidly secured to a spacing rod 3, whereby the chairs are permanently spaced the desired distance from one another. The chairs 2 and spacing rod 3 are made of wire of a suitable gauge which will insure the necessary rigidity.
In the form shown, each of the supporting chairs 2 comprises a single piece of wire which is bent to form a pair of vertical legs 4 having their lower ends looped to form an annular foot 5 disposed in a horizontal plane.
In operation, the improved devices are placed on the falsework with the spacing rods 3 disposed substantially parallel to one another at the desired intervals. The reinforcing bars are then placed in the throats 8 and are pressed downwardly into their seats.
Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claim.
I claim:
7 A bar support and spacer of the class described, comprising a spacing rod and a plurality of chairs respectively secured to said rod at'points spaced longitudinally of the rod, each of said chairs being formed of a wire rod bent to form an annular base and legs extending vertically from said base, upper end portions of said legs being bent to form co-operating clip portions for receiving and gripping a bar, said leg portions being welded to said spacer adjacent to but below the bottom of said clip portions so that a bar received by said clip portions is held thereby out of contact with the spacer and the latter serves to resist spreading of said clip portions.
Signed at Chicago this19th day of February, 1931.
