BECKER SHEET FILING Foa HEAVY LoADs Filed Nov. 20. 1930 In ver/of 39 man@ ./lorneys Patented Jan. 19, 1932 UNirsD STA ENNO BECKER,.OF BREMEN, GERMANY SHET :FILING FOR HEAVY LOADS Application filed November 2D, 1930, Serial No. 497,047, and in Germany .Tune 14, 1928l gagement for tliepurpose of ramming, ow-

ing to the dierences in distance between two locking members situated `on one side ot the webs of the I-sections, which arise on account of unavoidable inaccuracies of the single parts to be connected, which inaccuracies may be summarized in a structure of some greater length.

It is also known to provide the ends of the iianges of I-sections with locking members and to connect themby means of flat plates *provided with corresponding locking members. W'ith this construction also, diliiculties arise in ramming, from the employment of: the lat plates, which are not suiiiciently rigid and the ramming of which is diicult, or in the case of considerable lengths'even impossible. f 4V These detects yare obviated, according to the present invention, by a new combination between the I-sections and ilat plates, in

.which the plates are disposed on one side, (the outside) ofthe wall only. I

The I-sections appliedaccording to the invention are of the ordinary general form,

but have unequal vflanges with" that atone endsomewhat wider --and thicker and so of greater strengththan that at the other, The weaker flange of each section is designed to be slid or inserted vinto a plate .and rigidly connected thereto by welding, in known manner, while the wider and thicker ilange at the other end of the web forms an anchorage and counterbalance ior the greater mass Von the plate side, and brings the aXis of flexion as nearas possible to the so-called wall axis or middle planer-of the wall.

I-section walls,such as here contemplated,

presenta perfectly staunch smooth front surtace. This is a condition which is desirable for shipping, but is attended with the drawback that structural members which lare indispensable in the case of such walls, can be attached only in such a manner as to project. In order to remedy this drawback, ythe invention provides for the insertion, according to requirements, of channel sections between the plate irons in which channel irons, mooring rings, ladders etc: can be accommodated.

In ramming a wall of sheet piling, the piling members of irons gradually tend to assinne a slanting posit-ion, in that the upper end diverges towards the unrammed side of the wall. It is, therefore, necessary, now and again, when the tilt has become excessive, to compensate or return the joints to kvertical position. This is diihcult te accomplish in the case of closedlI-section walls because, unlike wooden piling members, the irons cannot be cut inthe form ot wedges. The insertion o'l the channel members enables the :tree locking edge to be rforced nearer to the linished wall, at the upper end, and to draw it further apart at the lower end, so that the free locking edge will assume the vertical position, as the inserted channell iron may comparatively easily be brought to a wedge shape of the required angle. In this manner, the insertion of the channel section enables balanced ramming to be obtained, or in other wvorcls to return the free edge of the piling torcoincide with a vertical line.

The drawings showr the sheet-piling wall in cross section intwo constructional forms, AFig. lillustrating one ormand Fig; 2 illustrating another. i i y In Fig. l a an' I-section, having a thick-v enedtlange Z2 at one end disposed at the side facing the solid ground, while the opposite Vflange c'facing the trench or water side in case of a quay wall is slipped in dove-tail and groove Jfashion into a fiat plate Z provided with lugs or projections e which tightly embrace said flange.

Compound units comprising an I-iron a and a plate CZ rigidly attached thereto as by welding are driven one after the other and n so as to provide a perfectly flat surface on the outer side of the wall.

In F ig. 2 a channel section f is shown inserted in the wall for the purpose of balancing the ramming and at the same time7 as already described, to accommodate struc` tural members (not shown) such as mooring rirgs, ladders and the like.

aving now particularly described and as` certained the nature of my said invention and in what manner the same is to be performed; I declare that what l claim is 1. A piling wall construction comprising fiat iron-plate sections joined together by interlocking marginal end connection one to another and I-shaped iron-beam members backing the same in right-angular or T relation; said members having their flanges at one end dove-tailed in and welded to the plate sections and heavier flanges at the other end providing firm anchorage and counterbalance for the structure as also bringing the axis of fiexation nearly as possible to the middle plane thereof.

V2. A piling wall construction comprising fiat plate sections connected by interlocking Ymarginal end fit with one another and I- shaped beam-members dove-tailed to and rigidly united with the mid-portions of said Section in T or right-angular relation; said members being unconnected at their opposite ends and thereat formed with enlar ed finges effecting firmer grip into the soil or counterbalancing purposes and bringing the axis of flexation nearly as possible to the middle plane of the wall structure.

3. A piling wall construction comprising fiat plate sections joined together end to end by interlocking connection with one another and I-shaped backing members connected to the midortions thereof in T or right-angular relation with laterally extended free ends formed Wider and thicker than at the others for as nearly as possible centralizing the mass and bri ing the axis of flexation toward the middle p ane of the wall structure, combined with U-shaped sections applied at intervals between the fiat plate sections for correcting or compensating inclination and providing for structural a pliances such as ladders within the face of) the wall.

4. In a piling wall construction, a structural unit comprising a fiat plate-section and an I-shaped beam-like member rigidly united thereto in T or right-angular relation by dove-tailed connection and welding together for driving or ramming as a unit; the free end of said beam-like member being formed with an enlarged flange or head for firm anchorage and counterbalance as also to throw the axis of fiexation nearly as possible toward the center plane of the unit.

5. A piling wall construction comprising Hat plate-sections having interlocking margina end connection together along the line of the wall, and I-shaped members having dove-tail and rigid connection with the midportions of said sections in right-angular relation thereto along their lengths; said members being formed with the flange or head at the end unconnected with the sections wider and thicker than at the other for nearly as possible oentralizing the-mass and bringing the axis of fiexation toward the middle plane of the Wall structure.
