INTERLOCK CONNECTION FOR FILING Filed NOV. 6, 1955 h alier H Ma a-e Patented Sept. 15, 1936 UNITED STATES- PATENT OFFICE: T 1

2 Claims.

This invention relates to sheet piling as used in conjunction with the construction of cofferdam retaining walls and such foundation work, and more particularly to an improved form of interlock joint for same.

One of the objects of my invention is to provide an improved interlock joint for steel piling the form of which will permit the manu-" facture of same by the usual methods employed in steel rolling mills.

A more specific object of my invention resides in providing an improved form of interlock joint by which the several piling members may be flexibly joined at their longitudinal edges, each joint being readily effected by a lateral insertion of one member of the interlock joint into the receiving member of the adjacent piling section, thus to obviate the necessity for raising the piling section being inserted, as is now the usual practice.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not con fined to the exact showing of the drawing, nor

to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing: 1

Fig. 1 is a perspective fragmentary view of a typical wall comprising my improved sheet piling sections.

Fig. 2 is a top elevational view of the improved form of interlock joint with the respective piling sections disposed at an angle with relation to each other, indicating the flexibility of the joint; and

Fig. 3 is a top elevational view similar to Fig. 2 but showing the respective members of the interlock joint being connected to each other by the lateral insertion of the male member.

Referring now to the drawing for a more detailed description thereof, the numeral 6 indicates the web of my sheet piling section which in the physical embodiment illustrated comprises a substantial straight panel. As required in certain types of work the web 6 may be channel shaped in cross-section so as to provide greater longitudinal rigidity for the structure.

At one longitudinal edge of the web ii is formed a reverse V-shaped bend, which comprises the male member 5 of my interlock joint.

The member 5 consists of a sharp bent corrugation comprising three substantial straight integral members 6, the inner member being integral with the web 4. v

The other member of my interlock joint is disposed at the opposite longitudinal edge of the web 4 and comprises a channel formation 1, the same being substantially C shaped in cross section. The channel formation 1 is composed of an arcuately formed portion 8 at one side thereof its free edge terminating substantially coplanar with the web 4. The remaining portion of the channel formation 1 is indicated by numeral 9 and is contiguous from the opposite face of the web 4 being formed in a rounded V bend. The free edge of each terminates intermediate the concave surface of the arcuate portion 8. The groove formed in the channel formation I comprising the

members

8 and 9 is adapted to receive the outer members 6 of the reverse V shaped bend 5.

As afore indicated the several sections of piling may be assembled one to the other by merelyinserting laterally the reverse V shaped bend 5 into the channel formation I substantially as illustrated in. Fig. 3. It will, however, be noted that my'interlock joint will also permit the longitudinal insertion of the bend 5 into the channel formation' 'i' such as is required when the final section of sheet piling is to be set in place. In such case the final section of sheet piling is raised substantially above the structure and its longitudinal edges are guided into the respective members of the interlock joint on the adjacent sections of sheet piling during the lowering of the final section.

It is to be noted that the novel form of my interlock joint effects a substantially tight connection as assembled with the respective webs d in coplanar relation or at an appreciable angle with each other, in that the respective members of the joint contact each otheralong at least two longitudinal lines. This fact will be apparent by reference to both Figs. 1 and 2.

What is claimed as new and useful is:

1. A sheet piling section comprising a web provided along one edge with a reverse V-shaped bend formation and along its opposite edge with a channel formation adapted to be interlocked from the side with a reverse V-shaped bend, of an adjacent piling section.

2. Interlocking sheet piling comprising similar sections each of which is provided along one edge with a reverse V-shaped formation and along its opposite edge with a channel formation, the channel formation of each section being formed so that the reverse V-shaped formation of the adjacent section may be interlocked with and released therefrom by lateral movement of the piling sections.
