9 Claims.

This invention relates to sheet piling and more particularly to corrugated sheet piling. This corrugated sheet piling is intended for, and serves the same purpose as any piling now on the market. It has long been appreciated that the value of corrugation in a piling section is considerable and probably, the lack of universal acceptance of patented corrugated piling designs may be ascribed to poor joint construction. The attempt w has apparently been in the past, to follow, in connection with corrugated sheet piling, the joint practice established in connection with sheet piling according to what may be termed rolled a shaped practice". This is evidenced by attempts to simulate the claw-like construction of joints in rolled shapes. This practice has resulted in weak, complicated, and relatively expensive joints. "A further result of this practice has been that in the manufacture of hot rolled piling shapes, strength has been concentrated at the joints because of the ease of manufacturing such joints when the metal is in a hot and soft state and, therefore, narrow panels with frequent joints have been the rule.

With the above considerations in mind, it is an object of my invention to provide a corrugated sheet piling in which the panels may be broader than conventional which, of course, results in more expeditious erection and greater simplicity. It is a further object of my invention to provide a novel joint for adjacent panels which will have improved sealing qualities.

It is another object of my invention to provide corrugated sheet piling, in which the sections will be readily nestable for shipping purposes,

I which will have a great column strength and resistance to turn-over on the driving end, which will have great beam strength distributed across the entire width of the panel instead of being m concentrated at the joints and which will be extremely versatile in that, it may be fabricated from a large variey of mill structures involving a range of gauges and metallurgical properties.

These and other objects of my invention which will be pointed out more specifically hereinafter or which willbe apparent to one skilled in the art upon reading this specification, I accomplish V a .by' that certain construction and arrangement of parts of which I shall describe certain exemplary embodiments.

Reference is now made to the drawings forming a part hereof, and in which:

Figure 1 is an end view of a panel of corrugated 55 sheet piling.

I Figure 2. is a plan view of the same. 7 Figure 3 illustrates one type of joint between adjacent sections.

.Figure 4 illustrates a diiferent type of joint adapted to have a sealing material joined into it. Figure 5 shows a slightly difierent piling section and a joint'between two adjacent sections designed for certain uses.

Figure 6 is a cross sectional view of a locking piece for joining together piling sections meeting 10:

at right angles.

Figure '7 is an end view of a slightly different locking piece.

Figure 8 is an end view of still another form of locking piece.

Figure 9 indicates an end view of a number of piling sections joined together and swung about an arc of a large radius.

Briefly, in the practice of my invention, I provide piling comprising a plurality of corrugated sections. The lateral edges of the respective panels are reversely bent to form joining elements and certain shaped locking pieces are provided for the purpose of joining piling sections which meet at right angles or similar large angles.

In Fig. 1, I have shown a panel l0, of cormgated sheet material in which the end portions II, are provided with reversely bent parts l2. A joint between two such adjacent panels I0, is shown in cross section in Fig. 3. It will be noted that the panel in Fig. l, is. such that adjacent panels will have to be reversely placed in order to provide for the interlocking joints and it follows from this that in closing a circle or the. like, an even number of panels will be required. It is to be understood that an odd number of panels may be used by the simple expedient of providing reversely bent portions on parts of the panel extending parallel to each other as illustrated, for example, in Fig. 5. In this figure the panel 20, is provided at the left end 2|, with a reversely bent portion 22, and at the right hand end 23, it is provided with a reversely bent portion 24'.

The joint between the panel sections illustrated, for example in Fig. 3, may be made for a snug. driving fit, so that the joint may be tight when driven or it may be modified as shown in Fig. 4. In this figure the two panels Illa, are joined at their ends, Ila, where they are provided with reversely bent portions Ila which, however, are bent somewhat in a hair pin shape. It will be clear that in this type of joint, the portions l3, may be filled with any type of sealing material for the purpose of providing a completely water tight joint.

Another minor joint modification is illustrated in Fig. 5 where the spacing between the arms 23 and 23a, and 24 and 24a, is greater than that illustrated in Fig. 3. This construction permits adjacent sections to be placed at a slight angle to each other illustrated by the angle A. In this manner, a gradual curve may be simulated as exemplified in Fig. 9.

Where adjacent panels meet at a right angle. it is necessary to provide joining or locking members or clips as will now be described.

Figure 6 illustrates a clip 30, for joining together two panels 3| approaching each other at substantially a right angle. It is to be noted that the sections 3| in Fig. 6, are of the type described in connection with Fig. 5, that is, adjacent sections need not be reversed for joining. Fig. 7, shows a slight modification in which the member 30a is off-set as indicated at 32. This type of clip or joining piece is preferable where the angle of adjacent panels is much greater than 90 since it prevents the piling from coming apart. It will be clear from a consideration of Fig. 6, that if the upper panel 3| were swung to the right so as to make the angle greater, the upper member 3| could swing out from the upper portions of the clip 30. The ofi-set 32 in Fig. 7 efiectively prevents this.

The joining clip 33 shown in Fig. 8, is provided for the purpose of joining. adjacent sections approaching each other at right angles where the sections are of the type illustrated in Fig. 1.

It will be clear that by this construction a large variety of gauges and metallurgic properties may be employed to suit the particular emergency of the occasionand it is to be understood that gauge and material do not form limitations upon my invention. It will be clear that various modifications may be made without departing from the spirit of my invention and that I do not intend to limit myself otherwise than is pointed out in the claims which follow.

Having now fully described my invention what I claim is new and desire to secure by Letters Patent, is:

1. Sheet piling comprising a number of panels of corrugated sheet metal, the lateral'edge bends of each of said panels being provided with reversely bent flat portions of a length substantially equal to the slant length of a corrugation, said reversely bent flat portions of adjacent panels adapted to be interengaged to provide joints in said piling.

2. Sheet piling comprising a number of panels of corrugated sheet metal, said panels consisting of a number of whole corrugations, the lateral edge bends of each of said panels being provided with reversely bent flat portions of a length substantially equal to the slant length of a cormgation, said-reversely bent flat portions of adjacent panels adapted to be interengaged when adjacent panels are reversely disposed, to provide joints in said piling.

3. Sheet piling comprising a number of panels of corrugated sheet metal, said panels comprising a number of whole corrugations plus one-halt corrugation, the lateral edge bends of each of said panels being provided with reversely bent flat portions of a length substantially equal to the slant length of a corrugation, said reversely bent fiat portions of adjacent panels adapted to be interengaged to provide joints in said piling.

4.
