ATTORNEY United States Patent 3 420,065 ADJUSTABLE BRACING MEANS FOR VER- TICALLY DISPOSED EARTH-SHORING PLANKING Edward J. H01], 320 Warwick Ave., South Orange, NJ. 07079 Filed Mar. 6, 1967, Scr. No. 620,803 US. Cl. 61-41 Int. Cl. E21d /06; E02d 29/00 7 Claims ABSTRACT OF THE DISCLOSURE A brace disposable substantially horizontally between vertical channels of spaced, upright beams, in bracing association with vertical, earth retaining planks serially arranged adjacent to two or more of such beams; the brace being telescopically or equivalently adjustable in length and/ or having articulatedly connected parts making the brace distortable in longitudinal form to enable it to coact with said beams to support said planks.
Field of the invention The prior art In shoring means hitherto developed, employing vertical planking, a series of vertical planks, even though sometimes interlocked along adjacent side edges, required cross-bracing to be applied thereto to prevent the assembly of planks from bulging inwardly of the excavation. Such bulging is undesirable and often leads to complete failure of the shoring means.
The cross-bracing, however, has been rather haphazardly applied to the planking and has usually consisted of wooden cross members which were required to be cut, on the excavation job, to lengths which appeared suitable to the workmen putting the shoring into place. This haphazard way of providing cross-bracing involves considerable uncertainty as to the adequacy of the shoring a This invention, to eliminate such haphazard procedure and the resultant evils thereof, involves retention of vertical planking which is placed into the ground at a planned excavation; but includes the use of side-channeled beams driven vertically either in front of or in back of a series of upright planks and telescoping (or the equivalent) cross braces which may be easily adjusted in length to fit into the side channels of the beams. These braces and beams may be placed either in front of the vertical planking (ie at the excavation-side face of the planking) to prevent inward bulging of the latter or in back of the vertical planking with stud-held cleats on the cross braces to engage the planking to prevent it from bulging inwardly.
These cross braces are not only adjustable in length but also, optionally, may be distortable in a horizontal plane to permit their use even though the related vertical beams may have been driven with their side channels not in perfect facing relation to each other. To permit such horizontal distortion, opposite end portions of the cross brace may be pivoted, at vertical axes, to intermediate portions of the brace.
In the accompanying drawing 'FIG. 1 is a perspective view of a portion of preferred shoring means according to this invention as viewed from within the shored excavation; this illustrated arrangement being particularly recommended for use where the earth being excavated is relatively soft with a high water content.

The embodiment of FIGS. 1-3
The shoring means of this, the first embodiment, comprise an aligned series of steel H-bearns 10 (only two being shown) driven vertically into the ground by any suitable driving means along a line corresponding approximately to the contemplated excavation. These H-beams are of such length as to extend downwardly approximately from the level of the earth before excavating to a point sufliciently below the floor of the excavation that they will be substantially supported in their upright positions by the earth into which they are driven.
Under conditions wherein the earth has some tendency to be self supporting, the H-beams may not require any supplemental support, but it is often desirable to provide supplemental support such as, for example, horizontal cross-struts, fragmentarily shown at 12, fitted tightly between H-beams at one side of a trench or other excavation and opposed H-beams at the opposite side of the excavation.
The first embodiment also comprises a series of vertically disposed corrugated steel planks 14, side edges of which internest to form a continuous earth supporting barrier in back of the series of H-beams; these planks being driven or otherwise suitably put into place in back of the H-beams.
FIGS. 2 and 3 show the corrugations of the planks 14 as being substantially angular, and the latter figure shows details of one suitable type of internesting for use between adjacent planks. Each plank 14 is illustrated as being more or less Z-shape in cross section with one side edge formed with a U-shaped socket 16 extending therealong and the opposite side edge formed with a bead 18- adapted to seat within such a socket of an adjacent plank.
Even though the planks 14 are internested, the pressure of the earth in back of the planking may strongly tend to bulge the planking inwardly of the excavation in areas between the H-bearns and break the internesting connections. As such bulging and/or breaking would constitute or lead to failure of the shoring, this invention also comprises one or more longitudinally adjustable, horizontal braces 20, extended between the webs 10a of successive H-beams with the ends of the brace or braces lying against rear flanges 10b of the H-beams and wedged firmly into place by suitable wedges 22 driven into place between the brace ends and front flanges 10c of the I-I-beams.
As illustrated as a component of the first embodiment, a brace 20 comprises hollow steel tubes 24a and 24b of rectangular shape in cross section; the former telescoping into the latter with a fairly close sliding fit. The brace 20, in non-extended form is easily located between successive H-beams and then extended to lie against and in front of the rear flanges 10b of said beams, after which suitable wedges 22 may be driven into place between the front flanges 10c of said beams and the ends of the brace to hold the latter against dislodgment.
The H-beams 1t} and the planks 14, ordinarily, are driven prior to or shortly after commencement of the excavating and the braces 20, in suitable number and spacing, are put into place as the excavation deepens.
It will be realized that the braces 20, by opposing inward bulging of the planking, also strongly oppose separation of adjacent planks 14 at their internesting edges. Thus, the corrugated planking not only supports the excavation wall very effectively but is sufliciently water tight to strongly oppose any excessive volume of Water from finding its way into the excavation.
The second embodiment (FIGS. 4 and Horizontal braces 30, which are utilized in the second embodiment, are fundamentally similar to the braces 20 of the first embodiment in that they are telescopically (or equivalently) extensible.
Each brace 30, as illustrated, comprises main, tubular members 32a, b, c, of rectangular shape in cross section, telescopically inter-associated by slidable, tubular sleeves 34, each having a cleat stud 36 welded to its front face. A cleat member 38 is held upon the stud 36 by a nut 40 threaded upon the stud.
When the shoring equipment is assembled, the studs 36 extend outwardly between successive planks 42 and the cleat members 38 overlie the inner faces of said planks to hold the latter firmly in earth supporting position and condition.
Where conditions call for additional studs, an additional stud-carrying sleeve 34 may be slidably positioned on the telescoping member 3212 as shown; and additional sleeves 34 may similarly be slidably positioned on one or both of the members 3242 and 0.
Earth shoring equipment according to the second embodiment may include angularly corrugated planking as shown in the first embodiment; but as internesting of plank edges is not resorted to in the second embodiment, the planking shown in the latter embodiment comprises sinuously corrugated metal planks 42 driven or disposed vertically in spaced relationship in an aligned series extended in front of a series of vertically driven H-beams (only two of the latter being shown).
The equipment of the second embodiment is employed somewhat differently than that of the first embodiment. Where the equipment of the second embodiment is employed, the earth, being of relatively low water content, is sufficiently self-supporting that, in many excavations, usually those of limited depth, the earth remains selfsupporting at least until parts of the shoring equipment are put into place as the depth of the excavation increases.
Thus, where earth of relatively low water content is being excavated, the H-beams 10 are vertically driven, in a series, in spaced relationship with the channels of successive H-beams facing each other; the H-beams being disposed along a line or lines substantially coincident with the planned excavation. The H-beams are preferably of such length and driven to such depth that their bottom ends will be below the planned floor level of the excava tion.
Then, the excavating progresses and, as the excavation deepens, the horizontal braces 30 are put into place between the H-beams and are telescopically extended to abut the webs 10a of the latter. The braces 30 are positioned against the inner faces of the front flanges 100 of the H-beams; and suitable wedges 22 inserted tightly between 4- the rear flanges 10b of the H-beams and the ends of the braces serve to hold the latter firmly in place.
When the excavating is completed or nearly completed, the metal planks 42 are vertically driven, or disposed in spaced relationship, in a plane extending in front of the H-beams. As this placing of the planks is done, the sleeves 34 are slid on the braces 30 so that the studs 36 line up with the spaces between the planks 42 and extend through said spaces, with the cleat members 38 in vertical attitude at the inner faces of said planks. After the placing of the planks, the cleat members 3-8 are turned to horizontal position and the nuts 4% are tightened to hold the cleat members firmly against the planks to hold the latter securely against inward bulging or dislocation.
A third form of horizontal brace is shown at in FIGS. 6 and 7 as comprising a central, tubular member 52 of rectangular shape in cross section and similar cross sectionally rectangular, tubular members 54, pivotally connected at vertical axes by pivot pins 56 to opposite ends of the central member 52; these pivotal connections preferably being such as to permit only limited pivotal movement of the members 54 relatively to the member 52 as indicated in chain lines in FIG. 6.
The brace 50 also includes tubular sleeves 58 slidably disposed on and extensible from the ends of the members 54 to enable the brace 50 to be extended and wedged into place similarly to brace 30 of the second embodiment. The sleeves 58 may include integral studs 36 which, if included, will permit the brace 50 to be used in much the same manner as brace 30 of the second embodiment. If the latter use is to be made of the brace 50, one or more studded, tubular sleeves 60 (only one being shown) may be slidably carried upon the member 52.
Moreover, a contractor doing an excavating job may keep a supply of end sleeves 58 with the studs 36 located in different positions therein (i.e., not necessarily centered thereon as illustrated) so that the inward projection of the studs 36 may be coordinated with the spaces between planks 42. The brace 50 is particularly useful where, as often occurs, successive H-beams are not driven with their flanges aligned in coplanar relation.
It should be understood that horizontal brace 50 may be employed similarly to brace 20 of the first embodiment, in which event, the studs 36 may be omitted if desired. However, even if said studs are not omitted in such use, they will not objectionably protrude into the excavation.
It will be understood that various types of internesting or interlocking means may be substituted for the head 18 and socket 16 arrangement illustrated in FIG. 3 and, also, that other types of corrugated planking may be employed instead of the planking shown in FIGS. 1-3. Thus, sinuously corrugated planks, such as shown at 42 in FIG. 4, may be employed in the first embodiment. In such a use however, the individual planks, extending in a plane in back of the H-beams, would not be spaced, but would be arranged. with side edge corrugations of each plank internested in adjacent side edge corrugations of adjacent planks.
It will be understood, also, that this improvement lends itself to various other forms of parts and other Ways of usage without departing from the invention as set forth in the following claims.
