SHEET FILING Filed Oct. 4,, 1928 I 2 Sheets-Sheet 2 Patented Dec. 9, 1930 CAMILLE BEAUJ'EAN, OF BRUSSELS, BELGIUM ASSIGNOR TO soorn'rn" AnonYME IDOUGREE MARIKAYE, OUGBEE, BELGIUM SHEET FILING Application filed October 4, 1928, Serial No. 310,403, and in France February 29, 1928.

Lengths of sheet piling are known which are formed by joining together elements of simple curvature arranged alternately on either side of the axis of the sheet piling.

the sheet piling thus formed a fairly high moment of inertia which is nevertheless limited by the dimensions of the cylinders of the rolling mills employed for rolling the ele ments of simple curvature.

The present invention relates to a sheet' piling formed by the juxtaposition of Z- piles which are each formed by the rigid union, before hammering, with two U-shaped members arranged alternately on oppositesides of the axis of the sheet pile, and of flat forms arranged between the opposing wings of each of the two U-members and in the extension thereof, the assemblage being formed by H-members having hollows of trapezoidal form, said piling being also provlded at one of its free wings with an H-memher or an arrangement of flat and H-members similar to the arrangement lnterposed'in the medial arm of the Z-piling.

The accompanying drawings illustrate byway of example and in a non-limiting manner various embodiments of the lnventlon.

The latter extends to the various original features wh1ch the arrangements shown comprise.

Figs. 1 and 2 are diagrammatic plan views of sheet piling in process of construction.

Figs. 3 to 17 show in end view various elements adapted for use in constructing the sheet piling.

2) are formed by joining together elements 2 of simple curvature arranged alternately on either side of the axis of the sheet piling, the axis to which these elements turn the concave side.

In the case shown in Figs. 1 and 2, addisuitable number and The additional sembled arrangements the additional secof simple curvature. I This arrangement makes it posslble to give- 'The invention is not limited Lsolely to lengths of sheet piling constructed in the manner shown in Figs. 1 and 2, but also extends-to all sheet piling comprising additional sections interposed between the elements of simple curvature placed alternately on'either side of the axis of the sheet piling.

.These various lengths of'sheet piling may be constructed according to the invention in different ways by employing fortheir forma-' tion members rigidly connected together in a arrangement before being driven in. I

In the case shownin Fig; l the length of sheet piling is formed by means of'members assembled together so as to form an arrangementsuch as the one shown in Fig. 15.

The invention provides however for the group. of assembled members driven in, in the first place, to be such as the one shown in The jointsbetween the various members are obtained by the engagement of male and female parts. By firstfof :all.driving in a group such as the one shown in Fig. 5, com

prising two male ends, it is possible tov pro-- ceed to the construction of the length of sheet piling by extending at the same time in the two opposite directions indicated by the arrows U and V (Figs. 1 and 2), while arranging always for each group of'members driven in to be guidedat one of its ends bya female The lengths of sheet piling (Figs. 1 and 2 part engagedupon a male part of a group of members previously driven 1n.

The same result is moreover obtalned 1n the case shown in Fig. 2. However in this figure the groups of members employed for the'formation of the sheet piling is different.

The lengthening sections 3 in fact, no longer form part of groups of members rigidly assembled before being driven in; the

group of members driven in first of all,'and comprisingtwo male ends, is however identical to the one shown in Fig. 1 and in 5. The. other groups of members driven in are of two types; one of them consists of lengthening sections provided at one end with an assembling section as shown in Fig. 12, and the other consists of groups of members similar to the one shown in Fig. 6.

The lengthening sections, instead of being formed by simple flats as shown in Fig. 9, may be of any section, such for example as the one shown in Fig. 10 or as the, one shown in Fig. 11. V I, I

It" goes without saying, that instead of rijg-' idly connecting members comprising, for in stance, an assembling section and a lengthenmg section or even an element of simple curvature, provision may be made for these.

members to be manufactured in such a way as to be integral with each other.

As shown in; the drawings, the assembling sections which operate by theengagement of male and female parts are such that these male. and female parts are formed by solid portions symmetrical relatively to a central common plane along which the connected parts are arranged in alignment with each Otherl.

The invention provides -moreoverfor the solid portions which engage to come into contact along planes symmetrical relatively to the invention is no way limited to the arrangements shown, but that it covers any arrangements of these members or of like mem- V hers. I 1

lVhat I claim is: p

1'. Sheet piling formedby the juxtaposition of Z-shaped members each formed by rigidly connecting before hammering two U- menibers' arranged alternately at each side of the axis of the sheet piling and the two opposing arms of which are in the extension of each other, flat members arranged between said opposing arms and in alignment therewith, H-shaped members having trapezoidal cavities or hollowed out portions connecting said arms and the fiat members, and an H- member with trapezoidal hollows arranged at the end of one of the two free arms; andfiat members and H-members similar to those above described assembled rigidly before hammering, arranged in alignment between the arms of the consecutive 'Z-members and connecting these.

2. Sheet piling formed by the juxtaposition of Z-shaped members each formed by rigidly connecting before hammering two U- members arranged alternately at each side of the axis of the sheet piling and the two opposing arms of which are in the extension of each other, flat members and H-members having trapezoidal hollows arranged between said arms and in alignment therewith, and

a similar arrangement at the end of one of the free arms.

lntestlmony whereof I have afiixed my signature. a,
