B. HOUGH, OF CHICAGO, ILLINOIS, TAXIS, ,0F ST. LOUIS, MISSOURLAND ONE-HALF TO METAL COMPANY, .A CORPORATION OF MAINE.

REINFOBCED CONCRETE CONS'.'LRUC'IIVON` To all whom 'it may concern Be it known that I, WILLIAM B. HoUeH, a citizen of the United States, residing at Chr.

Illinois, have invented certain new and-usef ul Improvements in Reinforced Concrete Construction, of 4which the following is a specification.

This invention relates to improvements in reinforced concrete construction and more particularly to an improved connection member for the support, spacing and locking of the reinforcing bars.

The object of the invention is to provide a connection member which embodies substantial improvements over known devices for the same general purposes in a number of respects to be particularly pointed out as the description proceeds.

An embodiment of the invention is illustrated in the accompanying drawings wherein- Figure 1 is a view showing the reinforcing bars in side elevation and the connection members in cross section. Fig. 2 is` a view showing the reinforcing bars in cross section and the connection members in side .elevation and, Fig. 3 is a perspective view showing in detail the improved construction of connection members.

Similar characters of reference designate corresponding parts throughout the several views.

The letter A designates the usual false floor or boxing which is removed after the cement has set and from which the reinforcing bars B are supported by the connection members C. The connection members C extend for any desired distance, transversely of a number of bars B, constituting common supports therefor and being ar` ranged at such intervals as' may be advantageous.

The member C consists of a sheet-metal strip formed at intervals corresponding to the intervals of the reinforcing bars in the y manner shown more particularly in Fig. 3. The elements of the formation shown in Fig. 3 are a pair of supporting lugs l and a bar engaging strap 2 arranged between lugs l. disposed longitudinally and of bow shaped longitudinal curvature. In producing the format-ion aforesaid, two parallel slits are formed in the member C, thus di- Specication of Letters Patent.

Application tiled January 9, 1911'.` Serial No. 601,575.

.ASSIGNOR OF ONE-HALFTO FREDERICK C.

BU'IIJIIIINGl` yidiii'githe latter throughout the extentofithe slits into three separated parallel portions, the two at the side of the strip being indicated by a and the intermediaterorieI being indicated by b. The lugs l are arranged at points within the portions a, being produced by the formation of downward bights preferably coincidently located. The formation of such bights results in proportionate lengthwise contractions of the member C, which provide for bowing upwardly the intermediate longitudinal portion b thus forming the latter into the finished strap 2 aforesaid.

In use the lugs 1 rest upon the false fioor or boxing A and the reinforcing bars which are threaded under the straps 2, are held spaced from the Hoor by said lugs and from one another by said straps. The latter have also the function of positive locks, serving the purpose of preventing any displacement whatever of the bars B.

The particular ad van tages of the improved construction are that the straps 2, in addition to their spacing and locking functions serve as braces to increase the stiffness of the connection member and thus prevent the bights, forming the supporting lugs from spreading or opening under the weight of the lreinforced bars; that the provision of a pair of supporting lugs in connection with the intermediate strap adds to the stability of the arrangement; that the straps cannot be broken off in shipping; and that the formation of the lugs and the spacing and locking strap does not weaken the member C to any material extent' since it involves no cross cutting of said member at any point.

The improvement is susceptible of slight modifications from the form described, for which reason no specific description herein contained is intended to put any limitation upon the scope of the succeeding claim which does not inhere in the language thereof.

Having fully described my invention, I claim:

In reinforced concrete construction, the combination of a plurality of horizontal reinforcing bars, and a combined tie and gage member extendil'ig transversely of the bars and consisting of a strip of sheet metal Ihaving); at points beneath said bars a pluratentaaug. 4., 1era.

vseveral short parallel strap-like portions separate from` one another' but integral at -each end with the main body of the strip, A'seid portions at each side of the strip being bent downwardly `from the plane of the body of the strip to formy legs adapted to rest at their lower .ends upon a form-work, and each having its upper `end underlying and' supporting one of said reinforcing bars, the main body of said stripL being substantrially straight and horizontal, and the incopies of this patent may be obtained for ve cents. each, by addressing the Commissioner of latents,

termediate strap-like portions being bent upi wardly from the plane of the body and eac-h overlying 4and retaining one of said reinforcing bars in place on its supporting legs, whereby the supporting bars are properly spaced from each other and from the form- Washington, D. C.
