BAR SUPPORT AND SPACER Filed June 23, 1930 WEW,
Patented Jan. 19, 1932 UNITED STATES PATENT OFFICE LAWRENCE F. EMIGHOLZ, OF CHICAGO, ILLINOIS, ASSIGNOR TO UNIVERSAL FOR-M CLAMP ('10., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS BAR SUPPORT AND SPACER vApplication filed June 23,
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 which is expansible and contractable so that it'may meet various requirements as to the spacing of the reinforcing bars; to provide a device of this kind which may be fabri cated out of asingle piece of wire; and to provide a bar support and spacer which may be made in a standard size for use in the con struction of concrete joists of different widths.
An illustrative embodiment of this invention is shown in the accompanying drawings wherein Figure 1 is a side elevation of an improved bar support and spacer in its contracted position.
Fig. :2 isa similar view, showing the bar support and spacer partly expanded.
Fig. 3 is also a side elevation showing the improved bar support and spacer expanded and showing a reinforcing bar in section.
Fig. 4 is an end elevation of the improved bar support and spacer.
The common types of bar support and spacer heretofore in use generally included a plurality of supporting members secured to spacing strips which spaced them uniformly from one another. In the manufacture of those devices, the supporting members and spacing strips were separately fabricated and then assembled in units. Each unit consisted of separately formed parts of different shapes which required several different dies. It was also necessary for 'the manufacturer to carry in stock a large supply of each part of the units.
In the construction herein shown, the improved bar support and spacer comprises asingle piece of wire which is fabricated to form both the supporting part and the spacing part. This obviates the necessity of carrying in stock a large number of parts of dif- 1930. Serial No. 463,237.
ferent sizes and shapes and also obviates the necessity of welding.
The support and spacer is preferably made of wire of comparatively heavy gauge, which possesses the necessary rigidityand which may be bent to the desired shape.
The reinforcing system involves the use of a'plurality of reinforcing bars 1, disposed horizontally above a falsework such as a joist so'lfit, not shown, and supported in substantially parallel spaced relation to one another by a plurality of the improved supports and spacers.
In the form shown, the improved bar support and spacer comprises a single piece of wire which is bent to form a pair of substantially U-shaped saddles 2 which provide seats for the reinforcing bars. The intermediate portion of the wire, which is located between the saddles, is bent upon itself to form a depending leg structure 3 which is expansible and contractable late-rally for varying the distance between the seats. The seats 2 and intermediate leg 3 are located in substantially a single vertical plane.
The outer ends of the wire are bent downwardly to form end legs 4, which diverge downwardly on respectively opposite sides of the vertical plane of the seats, as shown in Fig. l. The lower ends of the legs l are bent inwardly to form horizontal feet 5 which intersect said vertical plane at substantially right angles thereto.
In operation, the improved devices are placed on the falsework at the desired intervals and the reinforcing bars are then placed on the seats. The bar supports and spacers embodying these improvements are exceedingly simple in construction and operation, comparatively inexpensive to manufacture, stable when set up, and adapted for use with bars which are spaced at various distances.
I claim:
A bar support and spacer comprising a single piece of wire bent to form a pair of spaced seats and an intermediate loop forming a supporting leg, said leg and seats being located in substantially a single vertical plane, the outer ends of said seats diverging downwardly from said plane to form end legs, the lower portions of said end legs being bent inwardly to form horizontal feet intersecting said plane.
Signed at Chicago this 20th day of June,
LAWRENCE F. EMIGHOLZ.
