My present. invention, however, comprises. a:.

column {ai'i'd tied.- atri'n'tervals to pairs of disposing' thes e.bars.'in pairs relatively close a by the -helical.-speoer,-=.ye t: such securing lb close together that'in practice no." cultyzie experincedin atte'm'ptingftofold the structure ion-the joint spacing band or'wire; the nd 16 of the same I leling runs are caught around the wire formmg thes acmg means; one of said ends being shorter t an the other. It will thus be seen that a hinge joint is provided by the tying means that will permit folding or collapsing of the structure to permit of 1ts read handling. "njhcn set upon the job, additional pairs of bars or rods such as indicated at 1- in dotted lines are'employed in connection with the structure and these may be secured to the helical wire orband forming the spacing means at various-points. It is, of course, unnecessary to tie these additional bar's at every run of the spacer, since the main; bars employed in connect-ion with the same when in its collapsible condition, are tied at every run, and such condition 1'. ill insure the propcr'positioning of the spacing means.

In the form of structure shon in Fig. 7, the vertical rods or bars 1 are disposed singly, in rectangular form, \aiih a 'c-cnitinu ous spacer 2, thenshole being capable of folding or collapsing in substantially the same manner as the structure shown in Fig.1. V 1

it is obvious, of'course, that other forms of ties capable of performing the function (is sired may be employed-instead of-the specific device shown and described hereith, and hence my invention is not limited to the'use of any specific form of tying means for securing the rods and spacer together.

I claim:

1. A col apsible reinfdrce'ment for concrete construction, comprising a series of longitudinal'reinforcing bars or rods, a con tinuous s acing member connected to said rods, an said members with respect to each other and securing the same together, saidsreinforcing bars or rods be e disposed in pairs op osite each other and 'l he rods of each pair eing relativel, close together; I p

2. A llapsiblei-reinforcement for concrete construction, comprising pairsof longitudinal reinforcing bars or rods, a continuous spacing member connected to said rods, and tying means forming hinge oints connectlng s'aid rods and spacing member, said pairs of rods being disposed opposite each other and relatively close together, I

3. A collapsible reinforcement for concrete column construction,- comprising airs of longitudinal reinforcil bars or ro s,. a continuous spacing men: er connected to said rods, and t g means encircling the rods and secure to the' spacing member,

said means connecting said ars and spacing means permitting movement ofmember together but permitting movement of the samewith respect to eachother', said reinforcing bars .or rods bei disposed in pairs opposite each other an the rods of each pair being relatively closetogether.

he combination, m a reinforcement to eachother to collapse the structure.

5.- Thecombination, in a reinforcement for concrete column construction, of pairs of longitudinal reinforcing rods or bars, 'a-helicallycoiled wirepforming spacing means for said bars, and tying means at the crossing points of said. wire and bars, said means. ieing so disposed as to form horizontal hinge joints permitting movement 'oL'said bars and wire with respect to each other to collapse the structure.

" 6. The combination}: in a reinforcement for-concrete construction,'of reinforcing rods orba'rs, a helically coiled spacing member, and tying means connecting saidspae'ing member and the rods or bars, said tying means comlprising a looped member having substantial y paralleling runs with hooked ends,- the loop of said member being adapted to engage .the continuous spacing member while the hooked ends of the tie are arranged to pass around the rods or'bars and. engage the spacing-members at points beyond the loop. a

7. -.The combination, in a reinforcement for concrete column-constructiomof reinforcing rods orbars, a helically coiled spacing member,' and tying'means connectingsaid spaoingmember and the rods or bars, said tymgmeans com rising a looped member havingsubstantially paralleling runs with ends of unequal length-terminating in hooks, the loop of said member being adapted to engage the continuous spacmgmember while the hooked ends of the tie are arranged to pass around the rod or bars and engage the-spacing member at different points beyond the loop.

In testimony whereof, I have signed my 110 name to this specification, in the presence of two subscribing)witnesses.' 4
