Application July as, 1933. Serial l\lo. 682,684 C a fig omens; (o ve-71) My invention relates to reinforced concrete construction andmore especially to the reinforce-3 ment or steel 'work usable in floor construction,
the'present invention contemplating certain material changes or improvementsonwhat is shown anddesc'ribed in my P ior application for "patent filed June 16, 1931,Seria l No..5i4,863; I M
j The'pri'n'cipal object of this invention jisto provide steel reinforcing members for con'crete construction work which can bereadily and conveniently set intplace to present an interlocking framework'in the form of a grid made upv of longitudinaland transverse trusses of diiierent' sizes in fcrosfs, section, with; the smaller trusses".
passing through the larger trusses andf ada pted to be spaced apart according to requirements relative to'stress or load to be supported.
' A further object of my 'invention is to providev a V reinforcement for. heaVy duty concrete floors comprising a steel flframeworkor grid; of truss through truss construction which isadapted to be'einployed in connection with a sheetlmetal basein'the form of plates which are'in some instances temporarily connected to the beams so as to be removable from the reinforced concretefioor and in other instances locked or firmly? secured to the floor beamsby a keeper rail welded thereonand upon which the truss through truss H grid rests t'o be embedded inthe concrete and form part ofthe floor structure...
I Withthese principal objects inview invention contemplates a particular arrangement of truss, members having spacedfapart longitudi nal bars with separatedwebs whereby in the for 'mation 'of the main or longitudinal trussesspaces are provided between the webs and bars for the,
passage of the transverse trusses of smaller size in.parallelseriesbeing connected and braced together by'imetal clips engaging-the lower longi I tudinal bars thereof, thus providing a-' grid-like steel structure for reinforcing a concrete floor either with or without a permanentsheet metal j base, all ashereinafter described and specifically set forth in thdappendd claims.

In the'construction of. the trussthroughxtrus's Q the spaein g means in the form of a spajcingbar f gridrlike form of reinforcement the longitudinal and'tr'ansverse frame members or unitsmay be similarinconstruction; each consisting of three main" bars while in, other instances they extend longitudinally, as shown infthe drawings; and this reinforcement for the concrete flooring is usablev inconnection withtemporaryor removable forms, l asprovided for in Figs. 26 to 34l ir'iclusive', or permetal clip for-connecting the longitudinal t manent base platesas shown in' 'Fig. 10.
are each, made up of .a' main. upper bar; 20 and Fig. '16 isa sectional view enlarged showin fi he' "PAT N 22;,th'e {centrods forrning' 'thev webs extending d 7 them to receive the transverse trusses. The transverse trusses are similar in construction to the longitudinal trusses, that is to say comprise an upper main}bar'23 connected to the spaced apart lower bars 24, 24 by webs 25, and for the purpose of constructing the grid-like concrete reinforcement the trusses of one series, as the transverse trusses, are smaller in cross section than those of the other series so they can be slid through the same between the webs to rest on the lower bars. The transverse trusses may be located in alternate spaces or wherever required according to disposition of the stress to which the floor will be subjected; in other words, at certain portions of the grid forming the steel reinforcement the transverse'trusses may be located closer together thanat other portions thereof.
The formation of the trusses or reinforcement unitspermitthem to be shipped nested, as-shown in Fig. 11, and in constructing the grid the lon-. gitudinal trusses are connected together inparallel series b'y'means'of. metal clips 26 engaging the contiguous lower bars 21, 21, the purpose of the clips serving more especially to bind the q trusses togetherrather than increase the strength the bars andclampthem closely together, the bent end portion 26a being in the arc of a circlecorresponding with that .of .the circumferenceof the bar,,whi1e the arc of lthebent end portion 26b is slightly less than that of the circumference of the companion bar so that the last' mentioned end portion will be sprung over the barby the tap of.
a hammer. The clips remain in place to be em--' bedded in the concrete and although they are permanently attachedand consequently seldom required to'berem'oved the bent endportion 26b terminates in an outwardly projecting loop 260 that may be gripped by pliers should it be desired to remove the clip.
It will be apparent that by the use of different size truss members of the construction hereinbefore described the work .of forming anet work of steel reinforcement for all kinds of floors can be accomplished expeditiously for the reasonthat it is necessaryonly to set the longitudinaltrusses and after looking them by means of the clipspass the transverse trusses through thespacesintermediate the. webs, and in joining a series of transverse trusses with another series they are lapped as shown in Fig. 2-the ends of one series being l1 respects my invention provides a wide latitude or variety in construction. I
It is essential that thewebs of the larger truss members 'shouldbearranged so as to provide the required spaces for the passage. of the smaller truss members, but instead of having the webs or rods extend directly from the upper to the lower bars, as hereinbefore described; theymay, be disposed as illustrated in the modification Figs. '7, 8, 10V and-l6, which the webs extenddiagonallyat opposite sides of the truss between the upper bar 27 and lower bars 28, 28 and on a line therewith. In this instance also the rods forming the webs 29 are bent V -shape with the ends extended to bear on the lower bars to which they are welded. This form of truss possesses advantages over the other form and consequently the smaller truss members are similarly constructed, the upper and lower bars 30 and 31, 31 being connected by diagonal webs 32, and of course the angle of the bent rods forming the webs 29 of the larger trusses is such as to provide spaces to receive the smaller trusses. In this instance also thelower bars 28, 28 are connected by clips 26 in constructing the grid-like reinforcement. In either instance, however, this type of deck or floor reinforcement isvery cheap for the reason that the truss members or units can be shipped economically and when assembled provides'a mat ofmaximum strength consistent with the weight of steel employed. .Furthermore as the. truss members or units are easily handled in producing the net workwith the longitudinal bars of the trusses crossing each other the assembly canbe accomplished with greater. facility. by eliminating the expensive work of tying or welding loose members, itbeing necessary only to lay the larger truss members so as to be supported at their ends on the floor beams and pass the smaller trusses through them, and it'will be ob vio'us that in the completed structure the load carried by the top bars of the main trusses is transmitted through the webs to the bottom bars of said .trusses and the load carried by the top bars of the smaller trusses carried likewise through the bottom bars thereof to the main trusses upon which they rest.
Although different forms of .bar constructionmay be used in providing the truss through truss construction those illustrated in Figs. 17 to 22 possess peculiar advantages 'in a structure of this kind. In Fig. 17 the smaller or transverse.
trusses which extend through the webs 37 of'the spaced apart bars of themain trusses 38 are formed of four longitudinal bars designated by.
the numeral 39 connected by a transverse web 40, the longitudinal bars being arranged in upper and lower spaced apart pairs with the lowerpair.
spaced at a greater distance apart than the upper pair and having the web 40 extending between the upper pair of bars beneath the same and from the said bars to the lower pair respectively, .while in Figs. 18 and 19 four longitudinal bars 41 are also employed but in this form the.
upper and lower pairs of bars are close together with the bent rod or web 42 welded between said bars, The truss shown in Fig. 20 is a modification of the truss shown in Fig. 17, the four longitudinal bars 43 being spaced apart rectangular in cross section with the web 43a. extending across. the top of the upper pairof bars and from the.
latter downwardly to the lower bars. In each instance the webs are welded to the longitudinal bars, and it will be noted that these forms of smaller truss members are adapted for use in connection with main trusses in which the longitudinal bars are connected by vertical webs 45.. In Figs. 21 and 22 I have shown a form in which the web .46 extends from one of thelower longitudinal bars 47 diagonally to the upper, lon-.
' plates 35 are arranged with the corrugationsex tending transversely with respect to the floor oson-72 fIn'sQme instances itisdesirable tos'spacea the longitudinal: .trusses apartto aamore: OF'IBSS" ex.- tent and in Figs; 23 andriZdvI have shown; modie fications; of the metal-clip hereinbefore: described; in Fig. 23 thabent endportionsefiflsgoorof the clip having the connecting portion- .51' extended' to thainsertioni of a bentor curved. piece of metal or short bent ban52qbetween the.bars 2i, 2 1, and in Fig. 24- theconneotingportionfilof the clip is longer for separating. the bars of adjoinin'g main trussesa greater "clistance-apart the clipbeing; reinforced by means. of-a rail barror section 53.2 Theimodification shown in.Fig...25- ilius' trates the-adaptation of the metaivc1ips=26,-.here'- inbefore: described, in'connectin'g flat bar trusses, each truss consisting. of spaced apart longitudinal bars 57, 57 on a horizontal plane with each other and connected: by. webs 55a in: .the form :ofv rods bent'zig-zag betweenthe companion bars 57.

when removed will permit the 'plate floor construction todrop away from the concrete leaving only, the upper portion of theU-bolts-embedded therein. It will be notedthat i-n applying this plate floor .constructionto-thattype of I-bearn which thejunder side of the top flanges are inclined inwardly, as" shown in Figs. 28. and

Instead of using u-bolts I may employ vplairibolts '67 "as shown in Fig.;30, andfin this instance also the bolts remain in place after the removal of the plates forming. he temporary floor on which the concrete is poured. I
It, will be seen that in Fig. 26 the corrugated.
