4 Claims. (01. 6162) This invention relates to sheet metal piling of has for its object to provide a new section profile which adapts the section to useful employment in of positions. By the use of the.

v a greater variety profile herein shown and described, the same section may be used for the construction of a straight wallor a curved or angular manner of assembling In principle, the construction. according to the present invention involves the use of reversed single or double-acting wall, depending upon the the adjacent sections.

interlock edges in which the interlock axis of one edge is in angular relation to the interlock axis of the other edge. This principlemay be' embodied in various types of maybe attained by forming the axis of either one or both of the interlocks at an angle to the section axis. I. prefer, however, to form each of the interlock axes at an angle to the section axis. The invention is furthermore applicable to either straight web web sections. p To clearly illustrate vention, I have shown in the or arched or deep arched the principles of the inaccompanying drawings several examples of constructions embodying the invention.

. Figure 8 is a similar a straight web section to view illustrating the assembling of sections of the typeiillustrated in Figure 7, to form a straight wall; and

Figure 9 is a similar view illustrating the assembling of the sections, shown in Figure 7, to

form a curved wall.

Referring to Fig. 1

with its web l extendi to the section axis I 5,

which shows a pile section ng closely and in parallel it will be noted that at theright hand section edge the hook member H extends substantially in the direction of the section axis 55, while the guard member I 2 rises from the web at a pronounced angle to this axis before it curves toward the end of the hook. Inversely at the left hand section edge the hook member l3 rises from the web at a pronounced angle to the section axis l5, while the guard member l4 extends mainly in the direction of this axis. This unlike or dissimilar positioning of the interlock members at each section edge with respect to the main section axis I results in this and in all modifications within the scope of this inventionin the angular inclination of the two axes of interlock at the two to one another (for instance angle 7 in Fig. l) and with respect to the main section axis, as will be noted from the inclination a of the interlock axes l6 and I! in Fig. 1.

. If adjacent sections thus constructed are joined at like axes l5, are disposed in one case alternately on opposite sides of the pile wall, thereby neutralizing as it were, mutually their effect upon the direction of thewall, so that a In this figure for instance the opposite side of the wall.

In the other case, represented by Fig. 3, where unlike contoured section edges hand interlock angled of the left hand end of the figure.

Obviously the wall sired, to a considerable extent from a straight direction, and. the curved wall of Fig. 3 may be made to curve more sharply or less sharply. than wall with a straight main axisresults, as shown for instance in Fig. 2.

of Fig. 2 may vary, if deillustrated, because there is in all cases a certain angular displacement of the section joints permissible, without thereby unduly increasing the driving friction of the joint. But by forming and placing the interlock elements at both edges of each section so that their interlock axes are inclined toward one another and form angles with respect to the section axis, a very much greater adjustment of the angular relation of the adjacent sections to each other is made possible.

In Figure 4, the invention is illustrated as applied to an arched web section in which the web has the short flanges 2|, 22, the hook member 23 and guard 24 extending from the flange 2|,

and the hook member 25 and the guard member 26 extending from the flange 22. Here again the interlocks are reversed, and the angular relation of their interlock axes to each other and to the section axis 1'5 is in this instance attained by the bending of the flanges 2i and 22. Assembly of the adjacent sections with like contoured edges of adjacent sections in engagement, as illustrated in Figure 5, produces a straight wall, whereas the reversal of these connections, as illustrated in Figure 6, produces a curved wall. In either case, the particular direction of the successive piles may vary also in this modification to either side to a number of degrees from the normal relation.

In Figure '7, the section is illustrated in the form of a modified straight web type in which both axes are again,

the web 30 has two axes intersecting on a line parallel to its two edges, preferably but not necessarily midway between the two edges. The hook member 31 and guard member 32 project from one edge, whereas the hook member 33 and guard member 34 project from the other edge. The positions of these two members are reversed on the two edges, and the axis or" one interlock or joint is at an angle'to that of the other, and

as in the previously described modifications, at an angle to the main section axis. In this modification the two shanks of the web happen to conicide with the two interlocked axes of the section, which need not necessarily be the case. For the construction of awall, having a straight main axis, with this form of pile section, the like contoured section edges are joined with each other as illustrated in Figure 8, whereas the curved main axis wall is produced by assembling the sections with their unlike contoured edges, as illustrated in Figure 9. The adjustment of the interlock a number of degrees to either side of the normal, provides for considerable variation in the precise relationship of the adjacent sections to each other, whether in'the straight wall type of connection or in the curved wall type of connection. Also in this case it will be noted that in the straight wall form of Fig. 8 as in Figs. 2 and 5, the interlock angles are located alternately on opposite wall sides, while in the curved wall form of Fig. 9, as in Figs. 3 and 6, the interlock angles are all located on the same side of the wall.

The principles of the invention are applicable to either single or double-acting interlock joints of various shapes and constructions, provided they are reversed on the two edges. The pile may be straight web, arched web, or deep arched web.

, The form of interlock and the types of pile sections shown in the accompanying drawings are therefore to be understood as being merely conventional or illustrative. The particular angle at which the axis of the interlock at either side is disposed to the section axis 15 may be quite varied, so long as the two interlock axes are at an angle to each other and to the section axis l5. Indeed, their angular relation may be so chosen that with the normal amount of play permitted by the joints, the wall direction in the straight wall type of connection may assume as great a degree of curvature as the lowest degree of curvature permissible with the curved wall type of connection, so that a practically continuous range of adjustment from straight to curved wall construction of maximum curvature may be attained with one and the same form Ofpl0fi16.

As a further illustration of the adaptability of the one profile to various conditions, I may mention the connection of a number of the sec-. tions in the form of a straight wall, followed by a series of sections in the form of a curved wall; or the formation of offsets and angles by the appropriate selection of the type of connection.
