Patented cease, 1907.

Application filed July 8. 1907. Serial No. 382,617.

To all whom it may concern:

, Be it known that I, EDWARD NICHOLS, a citizen of the United States, residing at Cohasset, county of Norfolk, and State of Massachusetts, have invented an Improvement in Reinforced ConcretdConstructidn,

of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

l This invention has forlts ob ect to provide a novel 10. reinforced concrete construction whichis especially adapted for reinforcing concrete columns and beams, although the invention may be used in other reinforced concrete structures. I I

In'accordance with my invention the reinforcement of the concrete comprises longitudinal members in combination with other reinforcing members which have substantially a V-shape or U-shape in cross section with the edges of the legs or sides of said members is a transverse section through a column having the reinforcement shown in Fig. 8; Fig. 10 shows the blank from which the form of reinforcement shown in Figs. 1 to 5 may be made; Fig. 11 shows still another way in which a reinforcing member embodying my invention may be made.

- As stated above a structure embodying'my inven tion comprises longitudinal reinforcing members combined with auxiliary reinforcing members which have a substarniully-V-shape or U-shape in cross section, and which are arranged with the edges thereof secured to the ongitudinals.

. In Fig. 2 the longitudinals are shown at 3, and they may be of any suitable shape in cross section and of any suitable construction and are arranged in the column to extend longitudinally thereof. Theother reinforcing element is designatedh'y 4 and as shown it is substantially V-shape in cross section withthe edges of the sides secured .to the longitudinals by any suitable ineans. This V-shaped reinforcing member may be an expanded metal member, or a built up structure or maybe made in any suitable way.

In Fig. 2 I have show]; the V-shaped reinforcing member made of expanded metal, it being,made from p .a blank such as shown in Fig. 1 0 by slitting the blank blank over on substantially the centralline 7 and then drawing the edges 8 apart therebyto make the expanded metal reinforcing member shown in cross see member which has a continuousapex or edge 9 and also continuous side edges 8; said apex and. side edges being connected by the bars 10 which are formed'by' extend in the same direction and expanding the metal as described the bars 10 .on one side of said vmember incline in an opposite-direction from those on the other form of a truss which because of its peculiar shape is comparatively stiff.

inforcing members are employed, and they are situated ated at the corner of the column 11. Where the apex 9 of the V-shaped reinforcing members are exposed at the corners of thecolumn, as shown in Fig. 2, said apex acts to protect the corners of the broken. Furthermore since .these apicesare exposed in the completedcolumm it is possible to use them for supporting the false work or form within which the concrete column is made and thus it is not necessary form as is necessary wheresuch form cannot be supported on the reinforcing elements of the column itself.

column or beam thus formed can be transported withchipped or broken. This construction, therefore, enables me to build portable columns or beams This crete piles. i r v I,

In Fig. II have shown a construction similar to that shown in Fig. 2 except that a central longitudinal reinforcing member or core 13 is shown which may have any suitable structure. Where the form such as shown in Fig. 1 is used in a building, the angle-iron longitudinal members may have suflici cnt strength so that they'may be used to supportthe false work necessary to mold the-concrete structure, thusdoing away with much of the timbering which is-now necessary in erectdental to structures which are used temporarily as is the false work in a concrete building.

In Fig. 3 I have shown still another form of the inventionin which the-longitudinal member 15 is tubular,

the material between the slits 6,. as shown-in Fig. 10. By making the slits on both sides of the central line ,7 I

As shownin Fig. 2 a plurality of these V-shaped re to be directed outwardly with the apex 9 thereof situcolumn and prevent them from being. chipped orv tion in Fig. 2 and in 'side elevation in Fig. 6. f This I mannerof making thereinforcing member results in a side, and thus the expanded metal member is in the.

to use so elaboratea construction for supporting the This constr'uction'has the further advantage that a v out any danger of the corners of the column becoming construction may also be advantageously used in c0111 ing such structures. This method of use obviously involvesa great saving of time and labor and lessons very much the risk of accident which is always inci-v the edges 8 of the V-shaped reinforcing members being riveted or secured to the tubular member in some suitable way.

In Fig. at I have shown a way of embodying my reinforcing members in a column according to which the V-shaped members are arranged with their apices directed inwardly instead of outwardly. In this embodiment of the invention 16 designates the longitudinal members of the column, and 17 the V-shaped members 'ith their edges 8 secured to the longitudinals l6 and with the apices 9 directed inwardly. In this form of the intention no metal is exposed at the corner of the column for protecting the latter, but the benefit ofthe truss-like V-shaped reinforcing members is secured and also the benelit of the longitudinal reinforcing members.

in Fig. 5 I have shown. an embodiment of the invention similar to that shown in Fig. 2 except that the column is oblong in shape instead of square. This may be secured by making the two

sides

18 and 19 of the V-shaped reinforcing element of different lengths. In other respects the embodimentis like that shown in Fig. 2 with the edges 8 of the V-shaped reinforcing mem ber secured to the longitudinals 3. r

In Fig. 7 I have shown how my invention may be embodied-in a beam. It is usually the under side of a beam which is subjectodito tension and which needs the strength derived from the reinforcement, and in embodying my invention in a beam, therefore, I propose to use only two of the V-shaped reinforcing ele.

ments or the elements which would be used in one side of a square column and to place these two elements so the V-shaped reinforcing member may be made.

that they will properly reinforce the lower side of the beam, and if placed so that the edges 9 are exposed they will also protect the corners of the beam. As seen in Fig. 7, 3 deslgnates the reinforcing members which extend longitudinally ofthe beam, and 4 is the V-shaped reinforcing member. Said V-shaped reinforcing member has its edges 8 secured to the longitudinals 3 in any suitable way, and the apices 9 thereof at the corners of the beam.

'In Figs. 8 and 9 I have shown the V-shaped reinforcing members formed in a different way from that heretofore described. I In this embodiment the sides of .the V-shaped member are made of wire bent to form the cross bars 23 which extend from the apex 24, the latter being continuous In this form of the invention the edges 25 of the V-shaped nembers are not continuous but they are secured in any-suitable way to the longitudinal reinforcing members 3. I wil. preferably shape the wire forming the sides of the member so that the cross bars 23 on one side of each V-shaped member will incline oppositely to those on the other side whereby each V-shaped element will be in the nature of a truss.

In Fig. 11 I have shown still another way in which i In this embodiment said member is made from a piece of angle iron 30 in which slits are made at'it-s edges to form short lengths 31 which may be bent into the shape shown in Fig. 11. This forms all-shaped reinforcing 'member having the continuous apex with the bars extending at an angle therefrom, but the ends of the bars shown in Fig. 12, in connection with the longitudinal reinforcing members 3. form of my invention is to place one longitudinal reinforcing member 3 in the corner whcre the arms 31 cross, and another longitudinal reinforcing member 3 to The preferred wayof using this l which the ends of the arms .31 are secured. The ends "7 V shaped reinforcing members are made of T-iron,

shaped reinforcing membeis with a taper, they being wider at one than at the other.

Wherethe reinforcing member is made of expanded metal, as shown in Figs. 1', 2and 3, this can be accomplished by slitting the blank, as shown in Fig. 1.6, with the slits 6' radially arranged or arranged at different angles of inclination. As shown in Fig. 16 the slits at the right hand end have a less inclination than at the left hand end. here the blank is thus slitted and then foldedcentrally and expanded, as described with reference to Fig. 10, the V-shaped expanded metal member will be 'wider' at one-end thanat the other. When a reinforcing member'of this construction is used the result will be a tapering column, such as shown in Fig. 15. This feature of the invention is especially applicable where reinforced concretepiles are being made, because by means of it the proper serve to protect the corner of the finished structure whether it boa column, pile or beam.

One advantage of the expanded metal constructionshown in Figs. 1 to 7 is that the distance of the apex 9 from the longitudinal reinforcing elements may be varied by expanding the metal more or less, because the more the metal is expanded the greater will be this distance or the further the apex will project.

The expanding of the metal into the form shown in Figs. lto 7 is done by drawing the opposite edges 8 in oppositedirections either before or after the metal has been bent into Vsha'pe, and even after the metal has been bent one of the edges 8 may be moved upwardly or downwardly relative to the other edge thereby to expand the metalmore or less thereby securing the V-shaped member to the longitudinals. With this form of the invention, therefore, it is possible to adjust I the column or beam to be made after the metal has been expanded and While the reinforcing elements are being arranged preparatory to the application of the concrete.-

My invention is not confined to the illustrated em-- bodiments thereof. I

Having fully described my invention What I claim as new and desire to secure by Letters Patent is:

1. A reinforcement for concrete structures comprising longitudinailyextcnding reinforcing members and auxiliary rcinr'o ng members each having substantialiy a V- snape in cross sectl n. the edges of said auxiliary members being secured to the longitudinal members.
