RALPH A. MEG-ENITY, OF KANSAS CITY, MISSOURI.

CONCRETE CONSTRUCTION.

Specication of Letters ratent.

Patented Oct. 1, 1918.

Application led March 22, 1918. Serial No. 2523,890.

Be it known that I, RALPH A. MnenNi'rY, a citizen of the United States, resldmg at Kansas City, in the county of Jackson andy concrete construction.

The object of` my invention is to provide novel, simple, cheap and eiiieient means for securely attaching to concrete walls, veneer facings and fire proof partitions, and for attaching veneer facings to other cementitions bodies, such as piers, columns, beams, posts, lintels and the like.

My invention provides further a novel metal stud, which is durable, cheap to manufacture, which may be easily and securely built in a' concrete Wall or the like, and which permits of easy attachment thereto of wall ties at any desired height.

My invention provides still further a novel wall tie, which is particularly adapted for use in connection with my improved stud, and which may be easily and quickly attached thereto.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanaying drawing which illustrates the preferred embodiment of my invention,

Figure 1 is a vertical sectional view of a portion of a concrete wall and a brick veneer facing attached thereto with my improved studs and Wall ties.

Fig. 2 is a perspective view of a portion of an ordinary Woodenvwall form to which are shown temporarily attached two of my improved studs, the upper portions of which nre broken away.

Fig. 3 is a horizontal sectionalview on the line-3 3 of Fig. l.

Fig. 4 is an enlarged perspective view of a portion of one of my improved studs.

Fig. 5 is a plan view of a rod or wire formed to make a plurality of my improved wall ties.

Fig. 6 is an enlarged perspective view of one of my improved wall ties.

Similar reference characters designate similar parts 1n the different vlews.

1f designates a cementitious or concrete body, such as a wall, pier or post of the ordinary type. 2 designates the brick veneer facingv laid in cement or mortar 3 and which is attached to the body 1 by means of my improved studs and Wall ties.

My improved stud comprises preferably an upright strip of metal 4, such as rolled sheet steel from opposite longitudinal edges of which are cut, respectively two series of tongues which are bent laterally at right angles so as to form inwardly extending anchoring arms 5, each of which is provided at yits inner end `with a projection 6, extending at right angles thereto.

7 :and 8 designate respectively opposite side boards of an ordinary Wooden wall form, which may be retained in position for receivingy the concrete in any usual manner. Prior to pouring the concrete into the wooden form, the studs 4 are secured in an upright position to the inner sides of the board 7 For temporarily fastening the studs in their proper positlons in the form, each stud may be provided with a plurality of holes 9, preferably located respectively below the arms 5 in the wide portions of the stud. The holes 9 receive securing devices, such as nails 10, Fig. 2, which are driven into the board 7.

In order that the strain may be equally distributed, the arms 5 of one series are,

preferably, disposed in staggered relationship to the arms of the other series. By cutting the arms 5 from opposite longitudinal edges of the metal strip, 4, there is no Waste of material. As the arms 5 are integral parts of the strip, they are rigidlyconnected thereto and will, therefore, be retained in their proper horizontal position, when the concrete is poured into the mold.

After the concrete has been poured into the form or mold, and has become suiiiciently set or hardened, the mold boards Zi and 8 are removed, leaving the upright portions 4 of the studs embedded in the wall flush with one side surface thereof.

The veneer facing 2 is then laid, and between the desired layers are placed in the mortar or cement 3 my improved wall ties, each of which comprises, preferably, a. piece of rod or wire 11 having its ends bent respectively into two reversely disposed arcuate hooks 12, which are, preferably, of

like size and which are disposed in the s lme i horizontal plane. Each hook 12 is prefer ably ,of sufficient diameter to receive the widest portions of the stud 4. The Wall ties may, therefore, be attached at any desired height to thel stud 4.

When the facing 2 has been laid te a height at which it is desired to bond it to the Wall 1, holes for receiving the hooks 12 are gouged out of the Wall 1 behind the studs 4, and the hooks 12 are then threadedthrough the holes which have been gouged in the Wall so a-sf to respectively embrace the different studs, the wall ties being laid` flat- Wise upon the uppermost layer of the facing 2, as shown in-Fgs 1v. and 3.

A layer of morta-r 3 is then placed upon the top layer of'the veneer facmg so as to cover the Wall ties 11. v

The laying of the veneering 2 is then continued until the veneer facing has reached a height at Which it is desired to aga-in bond it to the Wall 1. At such time, holes are gouged in the wall 1 around the studs 4 to receive the Wall ties 11, and the latter are hooked to the studs and laid in cement or mortar on the top of the' veneer facing in the manner already described.

By having the hooks .1.2 of arcuate form, a minimum of material need be gouged out of the concrete Wall to enable the workman to thread the hooks around the studs.

. By having the wall ties engage the studs intermediate of the anchoring arms 5, and by haring the latter arranged in staggered relationship, the strain upon the studs is equalized, and a direct pull by thel wall ties is insured.

By having the hooks 12 revers-ely turned and of like size, the pull upon the wall tie is direct and equally divided, and either end of the Wall tie may be employed to engage a. stud.

The wall ties 11 may be cheaply formed from a single piece of Wire or rod, by forming therein a. series of portions, each having the shape of the letter S disposed horizontally, as shown in Fig. 5, each S-shaped portion being cut in two, as indicated by the horizontal dotted lines in Fig. A5.

The gage and Width of the metal strip 4. and the thickness of the Wire or rod used to make the Wall ties may be such as shall be required for the particular purpose in view.

I do not limit my invention to the structure shown and described, as modifications Within the scope of the appended claim, may be made without departing from the spirit of my invention.

That I claim is In a structure of the kind described, a wall, an upright stud embedded therein at the surface thereof and having anchoring means embedded in the wall,a veneer facing comprising horizontal layers, and a Wall tie secured to the facing between the layers and having a hook partly encircling and engaging the stud.

In testimony whereof I have signed my name to this specification.

RALPH A. MEGENITY.
