METALLIC REINFORCE FOR CONCRETE CONSTRUCTION,

the following is a specification.

My invention relates to the formation of composite concrete and metal structures of various kinds, such as beams, floors, walls and other members of a similar nature; and the purpose of my invention is to provide an improved form of stirrup and spacing means for supporting the reinforcing bars-for the concrete in proper position wlth relation to each other, and to the form or mold in which the beam or other composite member is made. The purpose and use of metal reinforcements for concrete construction being well known in the art, it is not thought necessary to describe the same herein.

My invention relates specifically to an improved form of stirrup and to spacing means combined withesaid stirrup, and 'is fully shown in the accompanying drawings, in which: I 1

Figure 1, is a sectional elevation of a mold or form, showing an improved form of stirrup embodying my invention, and one form of spacer which I may use therewith; Fig. 2, is a similar View illustrating a slight modification of the spacer shown in Fig. 1; Fig. 3, is a perspective view of the spacer shown in Fig. 1; Fig. 4, is a view similar to Fig. 1, showing a spacer for use therewith the stirrup or support shown in Fig. 1,

showing a modified form of spacer employed therewith; Fig. 7, is a sect1onal' elevation of the structure shown in Fig. 6; Fig. 8, is a perspective view of spacing and supporting. 1

In Fig. 1, I have shown a stirrup comprising verticalmembers -1, connected at the bottom by a plain run 2, and'having at the top inclined su porting arms 3, wlth ofl'sets 4 at fsaid supporting arms 1n order sition when placed in a mold or form without danger of tilting during the assembling Specification of Letters Patent.

bars are so placed.

I of the metallic reinforcingbars for the concrete. The offset portions may extend in the same direction, or in opposite directions as indicated in the drawings.

The u per and lower reinforcing bars are indicated at 5'and 5 respectively, and the lower series of bars 5 are placed directly on the lower runs 2 of the stirrups, and in the arrangement shown in Figs. 1

The reinforcing bars are separated and the upper row 5 supported by spacers 6, in

the structures shown in Figs. 1, 2 and 4, and when the lower set of bars are in place, the spacers are disposed in proper engagement with the stirrup and dropped onto the lower set of bars 5", and then the upper set of bars are laced on saidspacer. The spacer 6 is clear y shown in Fig. 3, and consists of a flat piece of sheet metal of suitable thickness, having recesses 7 to receive the bars, and turned edges 8 or other means to engage the vertical runs 1 of the stirrup. In this form of spacer as shown in Figs. 1 and 3, the notches or recesses 7 are offset with respect to each other, while in the form shown, in Fig. 2, the notches or recesses are directly above one another and the vertical width of the spacing member is proportionately greater.

In. the structure shown in Fig. 4, I have illustrated amodified form of spacer made of sheet metal and indicated at 6", which, in addition to having the notches 7 to accommodate the bars, has side projections 9 whereb the stirrup can be readily centered in the orm or mold in which the reinforced concrete structure is made.

In Fig. 6, I have shown a form of stirrup having coiled portions at the top of its vertical runs to support the outside bars of the upper set. These coils are indicated at 10 and the supporting arms 3 have the usual ofi'set ends 4 to provide a suitable support and prevent tilting.

In. Fig. 7, I have shown a sectional v ew of another part of my improvements in which the upper run of bars is connected by a member 23 having a series of loops 24, one for each bar; the projecting ends of the latter for support upon the form having the inclined arms 3 and the horizontal portions 17 held in place by staples 18. \Vhen and 2, three a A cent the stirrup having the' looped portions ends turned to form hooks for engagement in use, the member 23 will be mounted adja- 21, shown in Fig. 6.

If desired, he offset ends 4 of the supporting portions 3 of the stirrupsmay be secured by staples to the frame of the form or mold, although such securing isnot-es sential.

I claim: g

1. The combination, with a wire stirrup consisting of vertical runs and a cross member integral therewith, of a sheet metal supporting and spacing member constructed for engagement by reinforcing bars, said supporting and spacing .member being vertically disposed and extending between the vertical runs of said stirrup and having its with said vertical runs.

2. The combination with a stirrup comprising an integral U-shaped member, of a sheet metal supporting and spacing member carried by said stirrup and extending between the legs of the same, said spacing member being notched on its upper and lbower'edges for the reception of reinforcing ars. 3. The combination with a stirrup consisting of vertical runs and a cross member integral therewith, of a sheet metal supporting and spacing member for reinforcing bars having side clips in engagement-with said stirrup and extending between the legs of the, same, said spacing member being notched on its upper and lower edges forreinforcing bars. 1

4. The combination of a stirrup for reinforced concrete construction, and asheet metal spacing andv supporting member for reinforcing bars carried by said stirrup and extending between the legs of the same, said spacing member having side extensionsforming positioning means. p

5. The combinatlon of a stirrup for sup- 1 eraser porting reinforcing bars, and a sheet metal spacing and supporting member for said bars carried by said stirrup, said spacing and supporting member having side extensions forming positioning means and hook portions to engage the lefgs of said stirrup.

6. The combination 0 a stirrup for supporting reinforcing bars, and aspacing and supporting member for-said bars mounted for engagement with said stirrup, said spacing member having side extensions forming positioning means and hook portions to engage the legs of said stirrup.

7. A combined support and spacer for use with reinforcing bars and supporting stirrups, said support and spacer being formed of a single ply of sheet metal, having notches to accommodate said bars and integral hooks at its ends for engagement with the vertical runs of a stirrup.

8. A sheet metal support and spacer for reinforcing bars having notches to accommodate said bars, side extensions serving as positioning means, and side clips for engagement with a stirrup.

9. A support and spacer for reinforcing bars made of sheet metal and having notches in its upper and lower portions to accommodate said bars, and curved portions at'its sides forming vertical clips for engagement with the stirrup.

10. A support and spacer for reinforcing bars having notches in its upper and lower portions to accommodate said bar's, side extensions serving as positioning means, and

" side clips for engagement with a stirrup.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
