REINFORCING-FRAME Specification of Letters Patent.

A Applause med august 14, 190e. semi No. 330,551.

To all whom 'it may concern: r

Be it known that I, HERBERT E. VmTE, a citizen of the United States, and resident of .Youngstowrn Ohio, have invented certain new and useful Im rovcments in Reinforcing-Frames, of whic '1 the following is a specification accompanied by drawings.

This invention relates to reinforcing frames suitable for embodiment 1n concrete /and other masonry constructions, and the objects of the invention are to improve upon the construction of such reinforcing frames and render them more suitably ada )ted to meet the special' requirements of ifferent constructions.

Further objects of the Vinvention will hereinater appear aii'd to these ends the invention consists of a reinforcn frame substantially as hereinafter more fu Y described and claimed in this specification and shown in drawings, in which,-

Figure 1 is a si e elevation of a portion of a column and reinforcing frames embodying the invention connected thereto and toeach other; Fig. 2Vis a side elevation partly in section of a frame embod ing the invention supported between two ams or girders; Fig. 3 is an enlarged detail side view, partly broken away, illustrating the means for connecting the slats or tie pieces to the longitudinal members of the frame; Fig. 4 is 'an enlarged detail view, partly in transverse section, showing one of the clamps; Fig. 5 is a transverse sectional detail view, taken r through one of the clamps; Fig. 6 is a detail View partly in transverse section, showing one of the-anchor blocks for the frames.

Fig. 7 is a detail view of a modification of a portion of the frame.

It is well known that the stresses in a concrete beam or girder follow certain lines. Particularl the tensile strains be yinning at the top en of -a girder or beam w1 l follow a line descending as it approaches the center of the beam or girder and then asccndin as it approaches 'the opposite end. It t ius follows that the greatest tensile strain is at the bottom of the central or middle portion of the beam or girder, and hence it is desirable and necessary to place in central section or 'at the bottom of thc central section of the beam a eater bod'y of metal. ,I propose to obtain t iese desire ends by making a proper distribution of the metal by means of trusslike structures made by bending or deformcommercial shapes of iron or steel.

Referring to the drawings A represents a longitudinal base member, which may be a metallic rod or bar of any suitable cross section. .In this instance a bar square in cross section being shown by way of illustration. Connected to the base member A by means of longitudinal slats or tie piecesl B 1s another` or upper longitudinal member C, which is preferably one of the commercial shapes used in the construction of reinforcin members, and as shown, comprises a centra portion D, outwardly cxtendm portions E which extend from each'end o? the central portion D and diverge from the base memer A so that the distance between the base member and the portions E continuously increases as the outer ends of the reinforcing frame are aiproaehed. Preferably the extreme ends of the upper member C extend substantially parallel to the base A.

In`constructing the beam, the central portion D Aof the member C is placed upon the central portion lofthe base member A, and the two members are tied together by sets of slats B, the slats in each set bein f arranged preferabl f substantially paralle to each other, alt ough the arrangement may be varico, as desired. These slats as shown are preferably of much lighter stock than the ongitudnal members A and C, and are de tachably secured to said members by means of clamps, comprising the straps G, each formed of a continuous piece of metal bent 'into U-shaped form and adapted to slip over the members A and C at the desired points. Each slat or tie piece B is rovided with a foot H bent at an angle to tie tie ieee, and ada ted to lie within a strap G an substantial y parallel to one of the members A or C. Means are rovided for securely holding the bent ends I of the tiepieces, in this instance, each stra into whicli are adapted to be slipped plugs or blocks J recessed at L to receive the straps and provided with shoulders K which are arranged outside of the straps so that the blocks are revented from longitudinal movement when the ties are clamped in place. As shown, the ends of the tic pieces or slats B are placed between the plugs or blocks J and the longitudinal members of the being provided with apertures I,

frame, and wedges O are forced into .place between the feet l-l of the4 slats and thehinbe provided extending outwardly from the of the connecting piecesS,-wliich upper member l, and these additional ribs P may be secured by the `same. straps which lamp the members A and C together, and which' elamp Ithe ends of `the-tie pieces or slats B'to the. member C. g

- In Fig. 2 one inode of using the reinforeing frame illustrated, th'e 'endsof the frame-Alie.- ing placed between the' flanges .of the eye' berns` or girders Q and the whole:embedded in concrete. In Fig, 1 another and prefer- 'able mode of utilizing reinforcing frames is -lllustrated, in which ,li represent-s the upright metal ineinbers'of a]concrete-.eoluinnI and two reinforcing frames eoil trueted. in.

The base members of tliereinforeii'ig fra-nies `are also secured to the` up-- rights.` lt of the coluiniib v inea-iis ofl the -strutsl.'1 which struts-.are fastened-tt' the base members A and lo the uprigfils by 'may be arranged side by side and secured to ,gelber b5 means of Llie anchor liloek.\V,

whit-li also serves the purpose of fastening a suspended veiling to the frames,`or for fastening [Viartsof niarhinery oi' other ixtures' to the ceiling'. l'ii this instance the anchor blot-k lV is provided with jaws X, within which the base members ofthe beams are' platzed," and then tlie endsl Y of the jaws art" ben-t. over to rlaiuptlie anchor block upon the fi':i..nies. ln l*`ig. l Z represent-s a fixture of an)Y .suiluble eliarat'tei seeuieil l-o the :iii-

(ineof the particular advantages of thisiii vention resides in the fact that the subordinate-members ol' the. reinforcing frame ran be in'adi` of Ismall plee-en off stockY ordinarilytlirqln'n into the waste. Another advantage resides in the fact that'. t'he parts forming the reinforeing frame can be shipped to llie -niarluet in ltnorked4 down form, and may then. .be 'readily assembled at the pjlaee of using without more than the ordii'i'aiuf, slull ol" the iiuelianitl because the parts are 'connet-ted in. a very simple and ellirient manner,

and the. juni-tion members or clamps are all intert'liangf-able,- that is, any one clamp or strap may be placed in any desired. position to hold twoorvniore lparts together. Another advantiig i is the act that the different parts, int-hiding both the longitudinal -niain I, -ineiiibers and tlie subordinate members can be readily eut after slii|niieiit tothe seene of use and before assemhling,'and thus adapted to meet special requirements.

. It.' is of .great in'iportance that the reinforcing frames be capable of being connected with the vertieal reinforcing members. of a eolunnn for instance, which object is readily accomplished in aecordance with this 111-' with the beam or girderinterseeting it at right angles, but it may 'be connected with the. corresponding beamer girder extending `in the saine diret-tion as the frame in the eentiguous divisionofl the building v1n order to 'provide a continuous reinforcement from one side of 'the building to the. -other. The deformed upper nienilierof the truss-like reinforeingfraineprovides for the tensile strain, .and the otherparts of the frame provide' for the 'various stresses'to which eoiieretebodies are, subjected when heavily loaded. I In a;inediicationof the i'n'ain inent- 'ber's tif-tlierfmine iswsliown, in which the upper and lower members are integral instead .of sepaiite. .A solid bar A" is splitlut each e'iid to forni therbase member andthe upper members f `()b\'ioirisl.`\,v soinev features of this invention may be used 4without others` and the invention mar.' be embodied in, widely varying foriiis..'
