Application filed February is, 1915. Serial iiolres T all whom it may concern:

'Be itknown thatL-MIXOR CHA BER- LAIN, a citizen of the United States, residing at the city of Lebanoi1,c'ouiity of La-.' 'clede, and State of Missouri,- have invented a new and useful Reinforced Concrete Con structioii, of wliicli ,the following is a speci fication.

This invention relates to reinforced concrete construction, including such structures as annular or polygonal walls, solid mono lithic bodies such as posts and the like, and

all other structures composed of concrete; which may be erected or formed in accordance -Wltl1 the principles hereinafter eX-- plained. An object of the invention-isto provide .aconcrete structure, composed of suitable upright reinforcement-s spaced according to the requirements of the structure to be formed and having metallic reinforcing latlis secured thereto and supporting walls. or wall faces of concrete between which an open space remains, it being intended that the open space between the walls'm'ay be Ifilled with concrete so as to form a monolithic wall structure the :opposite surfaces of which comprise the concrete firstsecured to the metallic: laths. Another object of the invention is'to pro- V vide a concrete wall including parallel up right reinforcing members for the outer surface, of the wall, corresponding parallel upright reinforcing members for. the. inner surface of the wall, metallic reinforc ng- 'members uniting the. outer uprights with the corresponding inner uprights, metallic. laths secured to the outer and nner 1lp' rights,.respectively, two separate concrete wall portions embedding the outer and inner laths', respectively, and leaving an open space adapted to receive'concrte whereby the inner andouter wall portions may be monolithically united, the same constituting the form by which the concrete interposed between them will be held in place until it has hardened.

A furtherobject is to proiide a concrete structure comprising .walls constructed as above explained, incombinatlen with transverse reinforcing, elements connecting said walls and j supporting reinforced concrete floor structure.

Another object i's to provide an improved reinforcement for posts and the like, comi ing a central reinforcing member, p rallel reinforcing members connected to the central member,- intallic reinforcements extendingaround the series of reinforcements, .and concrete embedded and supported by the last-named reinforcements, and forming a "central open space adapted to receive concrete or not, as desired, whereby 'either" a hollow post' or a solid monolithic post' may be-produced, depending upon Whether] or not-the centralsp'ace is filled with concrete.

to be attained and accomplished by thein- 'vention'will be apparent from the follow-' ing description, reference being made to the -accompanying.drawmg in' which Figure 1 IS a sect onal" view illustratlnga outer and 'inner wa'llsurface being monol tliically united, and another wall, surface being shown without the concrete filling.

.From the foregoing it will be understood that one specific embodiment of,the invention as it might be employed 'in an annular.

wall, is illustrated in Figs. 1 to 5 inclusive; another specific embodiment of the invention as it might be employed in a polygonal wall, such, for instance, as the wall of a building, is illustrated in Figs. 6 to 12 inclusiveyand a third specific embodiment of the invention as it might be employed in the construction of posts and poles is illustrated in Figs. 13 to 23 inclusive. It will '-also'be understood that the particular form of corner reinforcing members illustrated in Figs. 10, 1.1 and 12 maybe utilized with equal advantage in the construction of the posts or poles.

In describing the different specific e m-- bodiments of the invention I will describesuch embodiments in the order above mentioned, it thus being necessary to make reference only to a single sheet of the drawing at any one time.

The structure illustrated in Figs. 1 to 5 inclusive, comprises an outer annular series of upright reinforcements, each. comprising a single sheet folded to provide three perpendicularly disposed lateral wings including one wing 1 of double thickness, and two wings 20f a single thickness of the sheet. These uprights are arranged in annular series with the double wings 1 extending radi-- ally inwardly, and the wings 2 of single thickness'of the serles of reinforcements bemg in annular alinement, as will be understood by reference to Figs. 1 and 4. Certain of the wings 2 are provided with integral tongues 3 by which the horizontal sheet I tively.

provided with laterally extended portions 10 metal reinforcements 1 are secured in place. I

Each horizontal reinforcement 4: is connected to the adjacent one in the same plane,

preferably by a tongue or reduced portion 5 on one of said remforcements passing through a slot near. the end of theadjacent reinforcement and then being bent back in clamping position, as will be understood by reference to Fig. 2. There is also an inner annular series of reinforcements, corre sponding in number and position to the outer series. Each reinforcement of the inner series comprises a piece of sheet metal folded to provide three perpendicularly disposed wings, the wing 6 of-which is of double thickness of the sheet and the two wings 7 of which are of single thickness of the sheet. The wings 6 are extended radially outwardly toward the wings-1 of the outer seriesof reinforcements, and the wings 7 of the inner series are in annular alinement. Each reinforcement of the, outer series is connected to a corresponding reinforcement of the inner series by a number of reinforcing metallic connecting devices. Each connecting device comprises a pair of plates 8 attached together, by suitable binding elements 9 and embracing the wings'l and 6 between their' outer and inner ends respec- The outer ends-of the plates 8 are bearing against the wings 2 of. single thickness on the outer reinforcements, and' the inner ends of said plates are provided with similar lateral extensions 11 bearing against the wings 7 of single thickness on the inner' reinforcements. Horizontal metallic reinforcements 12 are placed agalnstthe inner surfaces of the inner reinforcements, and

.may be retained in position in the same way that the reinforcements 1 are retained in.

position against the outer uprights. The reinforcements 4 and 12, and the connecting reinforcements 8 are further secured in po-- wall portion 15 is formed by placing a layer of concreteagainst and upon the outer-reinforcements'so as to engage and embed the horizontal reinforcen'ients 4, which will hold a the concrete until it becomes hardened. .When the concrete is applied in this manner there is-no necessity for the use of a form or mold to confine the concrete, because the 13o concrete being in a plastic condition may be placed by means of a trowel or the like,,similar to the manner that plaster walls are that said reinforcements will be embedded thereby and will support the'concrete until 'tween the outer and innerablingeach of said it-hardens. In a similar mannerv an inner concrete wall'cr Wall portion 16- is formed in connection with, the inner reinforcements, the plastic concrete being applied in the same way. The concrete of which the inner wall portion is formed is also forced into the spaces between the horizontal reinforcements 1:2 and against the outer surfaces of said re inforcements, thus embedding said reinforcements and forming an efficient inner wall. The entire structure may thus be formed if desired, in which event the'structure will be composed in an outer reinforced concrete wall 15, and an inner reinforced. concrete wall l6, w'1th an intervening space between sa1dwalls, and the rigid metallic connections 8 connecting the outerand inner walls andthus forming. a rigid structure.

If found preferable inany instance the space between the outer and inner Walls may be filled with concrete as shown at 17 in Fig.1. The concrete filler l7 i'spl'aced belatter have hardened and form amonolith-ic union with the outer and inner was. This concrete filler also embeds the metallic connections 8 which connect theouter and inner reinforcements, and give rigidity to the outer and inner wall portions 15 and 1.6, en-

wall portions to strengthen and support the other. As a result of this'arrangement the outer and inner wall portions 15 and 16 will retain the concrete which is placed therebetween as a filler while the filler is forming a monolithic union with said outer and inner walls. In this way the necessity for the use, of. forms or molds to retain the concrete and to shape the wall surfaces is dispensed with, the metallic reinforcements holding the concrete pensive forms or molds. the plastic concretebeing-- placed upon the outer and inner-reinforcemen-ts in a. well understood manner without the necessity of special training for such purpose;

"alls' after the scribed, each outer reinforcement being composed of sheet metal folded to provide three.

perpendicularly disposed ings of which the wing 18 isof double thickness. and the two wings 19 are of single thickness of'the also composed. of sheet metal each comprising a sheet folded to provide three perpen- 'dic-ularly disposedlateral wings, of which the wing 20 is of double thickness and the .two wings 2lfa're of single thickness of the sheet. The outer and inner upright reinv t'orcements'are placed a suitable distance apart with the

wings

18 and 20 of double thickness extending toward each other-andv connected by metallic reinforcing members each of which includes two plates 22 embracing} the

wings

18 and 20 between their ends and provided with lateral-extensions 23. These plates 22 are secured, together by cutting or stamping therefrom tongues 2% from one, plate which are pressed through similarly shaped holes in the other plate and thereby fastening; two plates together. The lateral extensions 23 press against the lateral .wings 19 and 21/ The outer and inner upright reinforcements support a plurality of horizontal reinforcements 25 retained in position by tongues 26 and bypla'tes 27 having extensions 28 extendingbetween said reinforcements 25 and clamping upon'the inner surface/of the wings 19 and 21 of single "thickness. The tongues :28 also clamp upon the lateral extensions 23, thus firmly con-' necting' the'outer and inner reinforcements so that each'will afford strength to the other. In the huter corner reinforcing" members the wings 19 of singlethickness are formedat rightangles to each other which will be understood by reference to Figs. 10 and 11. In the inner reinforcing members the-wings 21 of single thickness are also formed at right angles to each other, and in planes parallel with the planes of the wings 19 of the outer corner members. Thewings 18 and 20 of the corner reinforcements are con sheet. The inner uprightreinforce'mentsare the inner horizontal reinforcements 95 at the corners. In this way there is formed an outer series of upright reinforcements and a cooperating inner series of upright reinforcements, each seriesof uprights support- I mg a series of horizontal reinforcements 25.

The inner series 'ofreinforcements and the outer series of'remforcenients. are retained rigidly intheir proper relative adjustments by the connecting plates 22.

lnner reinforcements applied thereto by means of a trowel or otherwise, and the outer and inner walls thus formed. are pernnttedto harden after which I the intervening space is filled with a filler 31 of concrete which forms a monolithic union between the outer and inner walls placed and formed in a preceding operation. A reinforced concrete floor may also be formed.

in monolithic union with the walls when desired. The remforcements for the floor have then ends embedded in the wall structure,

and include a series oftransversereinforcing members which su-ppdrt an additional series of reinforcements. Each transverse reinforcing member comprises two metallic plates 35 placed side by side and having their lower edges extended laterally to form wings 36 and their upper edges also extended laterally to form wings 3T. Said p l'a'tes are fastened'together by stamping tongues 38 from one of said plates and extendlng said tongues through correspondingholes in the. adjacent plate and then clamping the tongues upon the adjacent plate. The reinforcing members 35 are supportedupon the upper ends of the wings 21 on the inner reinforcements, the wings of the inner reinforcements as well as the wings 18 of the outer reinforcements extending-between the plates 35,- thus preventmg lateral displacenient of said plates and supporting them rigidly in their proper adjustments. The plates thus formed extend from wall to wall as illustrated inFig. 6, and other series of upright reinforcements rise above said plates having their wings of double thickness extending between said plates asv indicated at 39 (Fig. 8). A series of horizontal reinforcements 40 is secured to'the lower flanges 36 of the plates 35 by means of tongues 41 on said plates 35, and clamping plates &3 which press against the reinforcements 40 and which have extensions 4:3 extending between the reinforcements 40. and clamping upon the flanges'136. After the reinforcements 10 have been thus secured in position a layer of concrete is applied thereto by trowel the wing 117 of single thickness of the sheet.

or otherwise, said concrete engaging and embeddingthe reinforcements 4:0 and the lower flanges 36 of the plates 35. The concrete thus applied. to and embedding the rein forcements 10 is'illustrated in the portion A of Fig. T5. while no concrete has been applied to the portions B.

After the concrete applied iii-this manner has become hardened addltional quantities of-concrete are placed "above the same and permitted to form a monolithic union therewith until the spaces between the reinforcing plates 35 have been filled with the desired'quantity of concrete as illustrated in the spaces C in Fig. 6. In this way the building may be constructed to any desired altitude and floors may be provided as needed. The floors thus constructed merge integrally with the walls, so that there is really no line of separation between the floors and walls when the building is completed.

Referringflnext to the structure illustrated in Figs. 13 023 inclusive, it will be noted that this structure includesa centralreinfor-cement composed of sheet metal folded to provide four perpendicularly disposed lat eral wings, of which the wings H are of -double thickness and the winged?) are of single thickness of the sheet. There are also four corner reinforcements each of which coinprises a single sheet folded to provide three perpendicularly disposed lateral wings, of which the wing 46 is of double thickness and In-this particular form the corner reinforcements are connected with the central reinforcements'by a number of metallic plateslS each of which is doubled upon itself and having its double portion engaged by thearms M) of double thickness on thecorner reinforcements. The. inner extremities of the plates 48 are clamped upon the arms of the central reinforcements and secured there- 4 to by suitable fastening devices 49. A series of horizontal reinforcements-50 are supported by the corner reinforcements by means of tongues 51 formed on the corners and embracing the parts 50 whereby the latter are clamped against the uprights. The adjacent ends of the parts 50 are fastened by a tongue 52 on one of said members extending through a slot in the adjacent end of the next or thesamemember and clamped so as to hold the parts in proper'arrangement. After the reinforcements have been thus arranged a concrete wall 53 is formed by embedding the horizontal reinforcements 50 in concrete and permitting the same to harden or solidify. After the'eoncrete wail 50 has been formed the space incl'osed thereby may be filled with concrete as will be understood by reference to Figs. 18 and 21, the concrete filler forming an integral union with the outer Wall so that the completed structure hasan integral concrete "body having em- -bedded therein the 1 reinforcements as described.

; Figs 18, 19 and 20illustr'atea modified form of corner reinforcements. In this structure the central reinforcements 5,4 are the same as that illustrated in Fig. 13. Each corner reinforcement comprises a sheet folded to provide three perpendicularly dised rings, of which the wing 55 is of double thickness and the wings 56 are of a single thickness of the sheet. Metallic-plates -57. connect the wings of the central.reinforcement 54 withv the wings 55, the latter being extended toward the center and presenting the wings 56 outwardly for sup {porting the horizontal reinforcements 50 which are held against the wings 56 by tongues 57 and plates 58. The plates '58 have extensions 59 extending between the reinforcements 50 and clamping upon the wings 56, as illustrated in Fig.20. The concrete wall surface 53 in this embodiment is applied in thesame manner as the concrete forming the wall 53 illustrated in F ig.'13, and after the wall has been formed the space is filled with concrete so as to form a monolithic reinforced'body. v

In Figs. 21, 22.and 23 the central reinforcement 59 is the same as that illustrated in Fig. 13. The corner reinforcements comprise a sheet bent substantially in the form of an I-beam forming two arms 60 of double thickness and at right angles thereto, an arm 61 also of double thickness of the sheet,

and two arms 62of single thicknessof'the sheet. In this structure the radial reinforcing plates 63 are. the same as the plates 48, the double edges of said plates extending between the walls of the'double arms 61 of the corner reinforcements, The horizontal reinforcements 50 in this embodiment are'supported by tongues 64, and by plates 65, the latter having projections 66 extending between the plates 50 and clamping upon the Wings 60 of doublethickne'ss. After the horizontal reinforcements have been secured in position in thismanner the outer concrete wall 53 is formed byv applying concrete to the reinforcements so as to embed the same therein and permitting the concrete to harden. After the concrete has hardened and formed the confining outer walls the space inclosed by said walls 1s filled with concrete so as to fo" m an integral or monolithic union with the inclosing walls,

thus providing a solid reinforced concrete post or body.

It will. be understood that there may be variations in the construction andarrangement of the parts comprising theinventmn without departure from the SPlIgt thereof.
