My invention relates ,to sheet piling of the kind used inconstructing sea walls for beaches, harbors, breakwaters, piers, dams, man made islands and like structures.

The invention pertains particularly to the type of sheet piling which consists of separate units, said units forming a cellular wall in lieu of a single wall and so arranged that the particular type of piling units comprising my invention can be interconnected with standard piling units, thereby forming a substantial wall or bulkhead, and requiring no further bracing than that contained within said sheet piling structure proper.

An object of this invention is to provide a sheet piling that possesses a superior rigidity than which is ordinarily obtained from similar structures and also resistant to the force of waves, storm stress and other interfering factors.

A further object of the invention is to provide a sheet piling having cross-section bracings integral thereto which correspond in shape to H beams, T beams, circular piling, square piling and similar shaped piling.

In the present prevailing construction of sea walls and like wall structures utilizing sheet piling, said piling consist of flat plates, the edges of which are fabricated in a manner to enable said sheet piling units to be interlocked thereby forming a continuous wall. I

The advantages gained by the utilization of sheet piling in the manner described is due to the fact that the said sheet units are flat and in some cases U-shaped. Such sheet units have a certain degree of superiority in resistant quality and durability.

The aforementioned type of sheet piling, however, does not offer the best desired rigidity and resistance to withstand heavy wind or storm stresses. The aforesaid type of construction while superior to other forms of piling, greatly add to the amount of materials required in addition to increased labor construction costs.

To overcome the aforesaid deterrents to the utilization of sheet piling as stated, in my invention the sheet piling is reinforced by the forming and without the riveting thereof into standard H or T beams.

In my invention the deterrents to the utilization of sheet piling as described are further overcome by reason of the manner of fabricating sheet piling sections thereby making additional reinforcement to said sheet piling unnecessary and also to render said piling unusually stress and storm resistant.

In further description of the invention reference is had of the following figures in which Fig. 1 shows an arrangement of an H beam having a section of flat sheet piling welded intermediately to said H beam.

Fig. 2 shows a perspective view of a sheet piling connection' utilizing the beam arrangement shown in Fig. 1.

Fig. 3 shows a fabricated sheet piling of the kind shown in Fig. 1.

In Fig. 1 there is shown a sheet piling unit having two parallel walls joined with two beams or projecting cross-connecting members 26 and 21, said beams being secured and welded into a detent in a flat sheet piling wall 28 at the sections 29 and 30 as shown in the figure. The wall 28 is heavily shouldered and reinforced in the area of the welded sections 29 and 3!].

In further description of Fig. 1 there is shown a unit of type and class known as a soldier pile. The difference in the aforesaid construction from that of the common type of similar function is in the fact that single sheet piling can be used in sea wall forming or like structures by utilizing the aforesaid soldier piling at interval sections in between said row of single sheet piling.

The flanges 26 and 21 projecting from the central body section, said central section being at the welding points 29 and 30, act to stiffen and reinforce a wall built of single sheet piling as stated. The soldier pile as illustrated in this invention furthermore enables a greater grip and greater displacement in the soil upon which the aforesaid piling rests and also providing anchorage in the surrounding soil.

In Fig. 2 there is shown the manner in which H-piling units are interconnected with standard sheet piling sections 15 and 16.

Fig. 3 shows a form of fabrication of the sheet piling 25, the inside ends thereof being linked to adjacent sections l5 and 16.

The piling unit as shown in Fig. 1 is joined with adjacent units at each side thereof by means of extended jointure sections, each of said sections having claws l6 and 11 which interlock with companion sections similarly equipped with the claws aforesaid.

The structure and shaping of claws I6 and I! are known to the art and hence do not require further description in the manner of construction or the joining thereof.

It is understood that the particular sheet piling described above is intended to be merely illustrative and. not illuminative of the invention, since it is obvious that the invention may be efiected by sheet piling arranged in many other different ways within the scope of the claims.

Now having described my invention what I claim is:

1. In an H piling beam formation including a pair of T beams, said T beams welded to a flat piling, said piling having interlocking means for interconnecting with adjacent piling, said interlocking means extending outwardly and beyond the limit length of said T beams in both directions from the central section of said formation whereby said beam formation may be interlocked with an adjacent beam formation Or to a single sheet piling.

2. In a sheet piling unit formation including two parallel walls and an intermediate wall approximately centrally located between said par allel walls, each of said parallel walls having a cross-connecting member integral to and extending from said respective walls, said crossconnecting members fitted into respective indents in the approximate central portion of the intermediate wall and welded therein, a bulged reinforcement portion contiguous to each of said indents whereby said welding way be strengthened and furthermore providing a reinforced body area for driver hammer operations upon said unit formation incident to installing said unit formation into position; an integral part of said intermediate wall forming linking means for interconnecting said unit formation with adjacent sheet piling unit-formations, said linking means extending horizontally in both directions beyond the limit length of the parallel walls of the sheet piling unit formation aforesaid.
