V "CO CRET RTEENFORCEMENT SUPPORT, I

V "Application 'filed ctober 16, 1929. -Seria1 1 To'. 400,02.

This inventionrelates to concrete reen-force-' ment supports and more "partlcularly to such supports for supporting-mesh reenfo'rcement material in the making of concrete roads,

" subsaana the like, and "has for its object the provision of asu'pport which will suspend the reenforcing material in the form until the concrete has been poured, after which the support may be bodily removed and relocated '10 to support other reenforcement as the pour ing progresses.

Another object of the invention isto pro- "vide a support'of this class which is composed ofFigure '1. I

of standard rolled metal sections and short lengths of rolled metal strips or sheets either vvelded, riveted or bolted together so as to "reduce the'first cost to* a minimum.

The supportO comprises abeam 2 composedoi' a section of rolled metal'channel which is of a length to bridge across the side forms A of the roadway." The, beam 2 is adapted to be positioned With its flanges horizontalandits Web or back vertical. The back or web of the beam 2 is provided at spaced intervals witha'plurality of series of holes 3 to receive key bolts 01' pins 4 for'attaching supporting legs 5.] The legs'5 are provided With a vertically extending slot. 6 to receive thebolts or pins 4. The pins 4 are adapted to be passed through the slotsG-and through selected ones of the holes 3 to'seciire the legs 5 in position and edges-'7 are driven into to form' recesses to 'receivethe longitudinal members" of the reenforc'ing material and thereby support said" material in suspended position between theforms. p 4

o n-avert d se relation by transverse bars 1 In operation, when it is desired to mount the support G, the pins 10 and 13 are removed and the support is bridged across the of the mesh reenforcement. \Vhen the sup-- port C is thus finally positioned the pins 10 and 13 are mounted to prevent displacement of the mesh from the notches 8 and to prevent displacement of the support.

After the support or several 'ofsuch supports are thus positioned the concrete will be pouredbetween the forms and, before the concrete sets or hardens, the pins 10 and 13 will be removed and the support will be shifted transversely of the roadway to disengage the longitudinal reenforcing members from the support, and the support will be lifted vertically leaving the reenforceinent suspended in the concrete.

In Figure 5 we have shown a modified form of mesh supporting leg 5 having notches 8 in its opposite edges so that it may engage the longitudinal mesh members at either side of the opening through which it projects.

In Figures 6 and 7 we have shown a reenforcement clamp D adapted to be used to hold the reenforcement in position in the notches 8 of the legs 5 instead of the pins 10.

This clamp comprises a pair ofinverted U-shaped members 16 secured in fixed spaced 7 In use, the reenforcernent mesh is first positioned in the .notches 8 of the legs 5 and the clamp D is positioned so that one set of its legs extend down along the outside ofone of the side forms A while its other. set of legs extend down through the reenforcement'mesh and engage one of the longitudinal members thereof so as to prevent transverse movement thereof.

In Figures 8 to 10 we have shown a modi- V fled form of support C composed ofa beam pins P on the opposite side of the 2* formed from a rolled-metal angle-bar.

The beam 2 is positioned with its flanges extending downwardly and with its apex forming its top edge or ridge. One flange of the beam 2 is provided with a plurality of spaced :ser'ies of'holes 3 to receive key bolts or pins P for attaching supporting legs 5. The pins 4* are adapted to be passed through holes in thelegs 5"" and through selected ones of the holes 3 'to secure the legs in position, and wedges 7 are driven "into slots in the flange to lock the legs in; position.

P 1 vided with extensions 17 cons sting of a vertical back portion andga I horizontal flange portion. The flange portion of the extension 17 a is provided with a hole 1 8 -alined witha beam hole 19 in the portion of the leg overlying the beam and said holes 18 and 19 are so spaced relative to the bolt or pin holes in the and to extend downwardly parallel with the legs 5 on the opposite side of the longitudinal reenforcing member entered into the notches 8 so as to prevent displacement of the reenforcement from the support.

Handles 14: are provided at each end of the beam 2'" to facilitate the handling of the support. I Y

In Figures 11 to 13 We have shown a still further modified form of the support C which comprises a beam2 formed from a rolled metal angle-bar having legs 5 permanently secured thereto byrivets 4 The legs 5 have one edge notched, as at 8 to form recesses to receive the longitudinal members of the reenforcement.

Handles l l are secured ateach beam 2 by rivets 25. v i

While the legs 5 and handles 14 are shown permanently riveted to the beam 2 it will be understood that, ifv desired, said parts may be secured in position by welding orbolting.

- It will be understood that the locking pins 10 and 10 may be omitted from the structures above described,-if desired, since in some instances they may be unnecessary.

While we have shown and described certain specific embodiments of our invention it will be understood that we do not wish tobe limited thereto since various modifications may be made without departing from the scope thereof, as defined in the appended claims. i

We claim: r

1. A concrete reenforcement support for supporting reenforcement in concrete roads and the'like, comprising a supporting beam adapted to be bridged across the side forms and of the of the road, and a plurality of depending vertical legs removably and adjustably mounted on said-supporting beam, key pins ceive'wedge members for preventingdisplacement thereof ,1

2. A concrete reenforcement support for supporting reenforcement 1n concreteroads and thelike, comprising" a supporting beam formed from a rolled metal angle-bar which is positioned with its flanges extending downwardly and its apex forming the top edge or ridge, said beam being adapted to be bridged acrossthe side forms of a road, and a plurality of depending Vertical legs secured on said beam, said legs being composed of short I lengths of fiat strip metal arranged so that 5 their flat faces are parallel with the longitudinal axis of said beam, and the edges of k said legs being notched to form recesses adapted to receive and support longitudinal members of the reenforoementQ In testimony whereof, We have hereunto
