J. OLELLINGER. REINFORCEMENT FOR CONCRETE CONSTRUCTION.

APPLICATION FILED MAR. 4. 1907.

JULIAN 0. ELLINGER, ,OENEW roan, QY.

REINFORCEMENT FOR CONCRETE CONSTRUCTION.

Specification of Letters iatent. Application filed March 4, 1907. Serial No. 360,310.

Patented June 9, 19 08,

To all whom it may concern: j

3 Be it known that I, JULIAN O. ELLINGER, a citizen of the United States, and residing in the city, county, and State of New York, have invented certain new and useful Improvements in Reinforcements for Concrete Construction, of which the following is a specification. V I i This invention relates to improvements in' reinforcements for 'beams, girders and the like, having their body portions composed of concrete or. analogous plastic materials.

It particularly relates to reinforcements wherein all of'the elements of the reinforce ment are designed, built, delivered, and

erected with all parts securely held together so that none will be inadvertently omitted when the concrete is molded around the same, and comprises longitudinally extending tension members connected with' each other by loops or'stirrups adapted to take I care of the shearing stresses.

One of the objects of the provide a reinforcement of the character stated, which willbe very efficient in use and may be inexpensivelyproduced. In pursuance of this object I have produced a beam or girder having longitudinally extending rods or, bars, forming tension members, and a shear member composed of a fixedly united,

system of longitudinal and transverserods which are arched between the tension members and are suitablyse'cured to the latter.

Such a construction forms beam 'or the same to the tension members;

or bars connected with each other by a web girder whichanay be produced at a minimum expense, and one in which stram imposed on.

any part of the shear member is transmitted throughout the series of longitudinal and 1' idJlSVGISQ bars composing the same, andv also to the tension members, thus making the entire network available to support $118,111"

imposed on any part thereof and to transmit This feature, however, is not broadly claimed herein as it is made the subject matter of claims embodied in my copending application -l lo.

373,633, filed May 14, 1907.

In further pursuance of the ultimate object of the invention, the tension members,

which are located at opposite sides of the beam or girder, are eachformed of two rods from which the ends of one of the rods 'or bars of each pair are severed and bent upward. Among the advantages .which this construction affords, especial attention is called to invention is to.

the fact that the weband rods of the shear membersle'nd themselves to an effective and yet economical mode of connecting the shear member to the tension members and to the positioning of the beam or girder in the mold, which, as herein shown, may be produced merely by extending the ends of the trans verse rods of the shear member through aper- 'tures inthe webs, and bending some of said ends into contact with'the outer faces of the web, allowing'others of said ends to efittend directly outward sufliciently to engage the side walls of the form and bending still others downward and extending them sufficiently to engage the bottom of the form.

Other objects will appear from the hereinafter description.

The objects are accomplished by. the construction set forth in the following description and illustrated in the accompanying drawing.

Referring to the drawing, Figure 1 is a perspective View of a reinforcement inade in accordance wlth the present mvention and shows the preferred construction thereof.

Fig. 2 is a detail planview of the means which constitute the shear member of the reinforcement. Fig. '3 is a sectional view of the reinforcement and the form in which the same is placed preparatory to the molding of the concrete or other plastic material around the reinforcement..

The same reference character designates thesame part in the several views.

- The present reinforcement comprises a pair' of side members A and A sac of which consists .;of a pair of rods a, a connected with each other by a web a ofthin sheet metal and adapted to be rolled, pressed or other- ".wise produced of the required shape.v The rod a of each of these side members is sheared from the web a at each end a suitable distance toward the center, and is left-unsevered at the central portion. v The ends of the rods (1 thus severed from-the web are then ,bentupward-at an inclinationto form vergently inclined portions 1.

I At suitable distances apart apertures 2 are provided in'the webs ofthe members A, A

for the rece tion of the ends of stirru s or loopsfb ,whic 1 are preferably of inverte approximately V form. The ends I) of some of vthese'rods b are turned downward to rest on the bottom d of the form D and thereby support the reinforcement within said form'durso I the, di- 1 mg the process of forming the concrete or otherv material around the reinforcement.
