ABSTRACT OF THE DISCLOSURE

Description
/skl
2~
The present invention is directed to a suppprting or hracing beam which is particularly adapted for bracing or suppoxting construction plates, sheeting piles or similar construction walls which are normally utilized in pairs and ara held in spaced relationship by spreaders installed transverse to the length of an associated trench.
It is common in large excavations to use so-called L-shaped plate material from which is made sheeting or trenching piles whose lateral vertical sides are generally of a T-shaped or C-shaped cross-section forming vertical guides which may be engaged by similarly complimentary contoured braces. Such sheeting piles or trenching piles are generally placed in a trench in iront-by-side and in superimposed relationship, depending upon the depth of the trench, and are interlocked at adjacen~ contiguous vertical and/or horizontal edges. These same trenching or sheeting piles are also held in spaced relationship from each other by braces to resist the collapse of associated trench walls or like excavations.
A simpler version of such heating piles, trenching piles or building walls are equiped with vertical C-shaped guides or box beams which may receive associated spreaders or guide heads of building walls which are transverse (generally normal) to the longitudinal axis of an associated -~
trench. As such building walls permit preassembly to form rectangular closed building walls, they are normally termed "excavation walls" in the trade. Such excavation walls are generally connectedly rigidly at least .in pairs by means of spreaders or the like and are emplaced in such pairs in pre-excavated trenches.
~ /skl 5~5~
The difficulty resides not simply in bracing by spreaders or the like such pairs of excavation walls, sheeting piles or trenching piles from each other ~o prevent the walls of a trench from collapsing, but to effect the support of such excavation walls in areas that which a trench is crossed by conduits or the like,and it is impossible to utilize excavation walls in these areas. In other words, the excavation walls are generally placed one on opposite sides o~ the conduit and though they are held in place by spreaders or spanners noxmal to the longitudinal axis of the trench,those excavation walls on the same side of the trench but on opposite sides of the conduit have not been inter-connected in a suppor~ing fashion. Heretofore in such cases the trenching excavation had to be interrupted and temporary planking was utilized in the old conventional manner which is obviously laborious, time consuming, not particularly safe, and generally interferes with overall construction deadlines.
Similar problems to a conduit crossing a trench transversely results where a trench of a predetermined width suddenly becomes larger in width which is s-mply incapable of being accommodated for, if transversely narrow trenching walls are unavailable.
In keeping with the foregoing, it is a primary object of the present invention -to provide a suitable supporting beam or brace which can stand the distances between adjacent excavation walls, construction walls, or the like, as, for example, excavation walls spaced from each other on the same side of a trench between which might pa~s a conduit, the supporting beam preferably being telescopic

in nature and having pivoted thereto at opposite ends generally C-shaped brackets defined by a bight, a pair of legs, and end walls opposing each other to define therebetween a groove with the groove having a longitudinal axis parallel to the axes of the pivotal connection between the C~shaped brackets and the associated supporting beam whereby the supporting beam can be connected between and in supporting relationship to spaced aligned construction walls or excavation walls on the same side of an associated trench.
Still another object of this invention is to provide a novel supporting beam of the type aforesaid including clamping means carried by each of the bights for clampingly securing each C-shaped bracket to an associated guide head or plate of the excavation wall or construction wall.
A further object of this invention is to provide a novel supporting beam in which additional clamping means are associated with each bight of each C-shaped bracket in - order that either clamping means may be utilized to draw a guide head or plate of an excavation wall against and in clamping relationship to an outer surface of the end walls or against an inner surface of the inner surface of the end walls of the C-shaped brackets for clamping purposes.
By providing a novel supporting beam of the type aforesaid, the conventional "soldier beams" found in wood construction are totally replaced while the major advantage obtained from the construction of the supporting beams of this invention is that they may be fastened by means of the C-shaped brackets to the vertical C-shaped or T-shaped end beams or box beams of excavation walls or to the C-shaped box beams of excavation walls or plates or like trenching, ': ' :

and in this manner they are rigidly connectable in a continuing or ongoing fashion to buildup relatively large trenching areas. Furthermore, the pivoting associated with each C-shaped bracket and its preferably telescopically extensible bracing mernber allows most any type of construction to proceed at virtually any angle, as might vary when trenching direction or excavation is changed. Due to such pivo-ting, the supporting beams of this invention might, for example, be utilized in areas where a narrow trench widens and then renarrows again to support and interconnect the excavating walls along the narrowing and widening trenches.
With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following . detailed description, the appended claims and the several views illustrated in the accompanying drawings.

(not shown~, another pair of excavation plates in a wider area of the trench, and four spreader bars of this invention connecting together adjacent ends of the excavation plates~
A novel supporting beam constructed in accordance with this invention is generally designated by the reference numeral 12 in Figures 1 and 2 and is shown positioned between construction walls or excavation plates 1, 1. The right hand side of the excavation plates 1, 1 in Figure 1 are the outside thereof which are normally imme~iately adjacent the wall of a trench,while the left side of the same plates 1, 1 are inside the trench and suitable conven~ional spreaders (not shown) are received in the guides 3 carried by the excavation plates 1 to hold oppositely unillustrated excavation plates against the opposite unillustrated side of the trench in Figure 1. Each of the excavation plates or walls 1 also include vertical bars, guide heads or braces 2 which are welded or otherwise rigidly carried by the excavation walls 1 and generally run the length thereof from top to bottom on both sides of each of the excavation plates 1. It is to these guide heads or plates 2 that the supporting beam 12 is interconnected to reinforcingly brace and support the excavation plates 1, 1 from each other in the manner most readily apparent in Figures 1 and 2.
The supportiny beam 12 includes an elongated member 12a having ends (unnumbered) telescopically received in tubular elongated members or end portions 11, 11.
Suitable adjustiny pins and alignable bores are formed in the members 11, 11 and 12 in order that the elongated member 12a may be ad~usted in its length .relative to the end : :

The end portions ll, ll are connected by pivot pins lO, lO to C-shaped brackets 9, 9 tFigure 2) whose ~ight (unnumbered) are welded or otherwise fixed to bights 7 of generally elongated (Figu.re 2) C-shaped clamping brackets or brake shoes 5, each of which includes a pair of legs (unnumbered) generally normal to the bight 7 and terminal end walls 4, ~ in planer opposing relationship to each other which define therebetween a groove or slot (unnumbered). Clampin~ means in the form of bolts 8 are threaded in nuts (unnumbered) welded to the bight 7 of each of the C-shaped bracXets, and each bolt 8 carries a clampin~ jaw or plate 6 which clamps the guide head or strip 2 of each excavation wall 1 against inner surfaces (unnumbered) of each of the terminal walls 4 of the C-shaped brackets, thus rigidly connecting the supporting beam 12 between the excavation plates l, l in the manner clearly apparent from Figures l and 2. A cover plate 13 is welded to one of the legs of each of the C-shaped brackets and covers a gap between each excavation wall 1 and its associated guide head or strip 2. The same cover plate 13 is used for alignment purposes in the manner best shown in Figure 5.

of the drawings, the same construction as that heretofore .:
described relative to ~igures l and 2 is illustrated .

except that in addition to -the clamping means or clamping bolts 8, 8 and the associated jaws 6,6, additional clamping means in the form of bolts 18 are shown in Figures 3 through 5 with the bolts being received through apertures (unnumbered) in a securing plate 16 which spands legs 14 of a generally inverted C-shaped vertical box beam forming part of an excavation plate or construction plate (unnumbered) with a C-shaped vertical guide plate or box beam (unnumbered) of the latter being connected by a weld to the inverted C-shaped box beam, generally along the common bight wall 15 therebetween. Thus, as the bolts 18 are tightened, the plate 16 is drawn to the le~t to clamp the end walls 14 of the excavation plate against the outer surfaces (unnumbered) of the end walls 4 of the C-shaped clamping bracket 5 of the supporting beam 12.
Thus, depending upon the particular construction of the excavating plate and its associated box beam 14, one might utilize the bolts 8 and their associated clamping jaws 6 (Figures 1 and 2) or the bolts 18 and their associated clamping plates 16. Also, -the bolts 8 or 18 might preferably be housed in horizontally elongated slot 17 (Figure 4) to permit limited adjustment while horizontal adjustment might be achieved by elongating the slots associated with the bolts 8 or 18 vertically, as is indicated by the elongated slots associated with the lowermost bolt 18 in Figure 1~ opening through the lowermost edge of the bight 7.
In Figure 6 of the drawing, two pairs of excavation plates or walls 19 ! 19 are each in alingment with an excavation plate or wall 20, 20 and they are held by conventional -- g _ .

Reference numeral 21 indicates a conduit which is passing generally transversely through the trench (unnumbered) which is supported by the excavation walls 19, 20. Preferably corrugated sheeting 22 is applied to ~he exterior surfaces of the spreader bars 12 ~o futher support the trenching while allowing gaps (unnumbered) between the corrugating sheeting 22 through which the conduit 22 may project in the manner readily evident in this figure.
In Figure 7 like excavating walls 19, 19 in parallel rel~tionship to each other are spanned by a spreader (unnumbered) disposed between vertical guides 3.
In this case, the supporting beam 12 stands across the ends of the excavation walls 19, 19 at the end of a trench and may have resting thereagainst or otherwise secured thereto like corrugated sheeting 22 for supporting the blind wall (not shown) of the associated trench.
In Figure 8 the upper excavating walls 20, 20 are in alignment with the lower walls 19, 19 and represent narrow portlons of a trench whereas excavating walls 23, 23 represent a widening portion of an associated trench (not shown) with the ad~acent vertical edges of these -~
