w. c. KQHLER ET AL HOLLOW FILE FOR SHEET PILINGS Filed Jan. y 14, 1937 Patented Jan. 4, 1938 UNITED STATES HOLLOW PILE FOR SHEET PILINGS Willem Coenraad Kiihler, Amsterdam, Netherlands, and Arthur Mauterer, Dortmund, Germany Application January 14, 1937, Serial No. 120,479% In Germany January 18, 1936 2 Claims.
This invention relates to a hollow pile for an iron double walled sheet piling which differs from the known constructions in that it consists of component parts which are very easy to roll,
5 produces smooth outer and inner walls without projecting parts and enables tightness in the locks to be obtained so that it can be employed for instance for building the walls of dikes across valleys and similar structures.
It has already been proposed to build up hollow piles for sheet pilings from four U-girders. In this construction only the outer irons have lock-forming ends and the arrangement of lock ing bars is not provided for. Moreover, the outer irons are diflicult to roll and also only up to a certain size. Double walls are further therein, the individual elements of which consist of two outer sections interconnected by means of a locking bar arranged in the neutral axis of the wall. In this instance relatively large open spaces are formed between the shut off hollow spaces and can only be filled with a large quantity of waterproof material.
The invention sets out from the known hollow pile for sheet piling composed of four U-girders in which the U-girders forming the flanges have their open side directed inwards and the U- girders forming the webs have their open side directed outwards. The novelty consists in that go the edges of the individual girders are bent over or thickened in club-shape so that the abutting irons form a bulb which can be gripped by the claws of an I-section locking bar of known type.
This new hollow pile for sheet pilings presents 3.3 a number of advantages over those of known construction. It is possible to make the connection between two neighbouring piles with two locking bars of any desired thickness in an absolutely perfect manner and also to allow in the 40 section according to the invention a relatively large clearance between each locking bar and the ends which it grips so that the ramming can be carried out without difficulty and much more easily and more reliably than with sections which 45 only allow slight clearance in the locking connections. The arrangement of two strong looking bars in or on the outer sides of the hollow piles not only secures the connection under all circumstances but also increases the moment of 50 resistance of the whole wall. By this type of connection between the outer and inner girders a moment at fixed end, in the case of transverse stressing of the outer girders, is produced in their ends and favorably influenced by the 55 locking bar. Owing to the special kind of connection of the four girders at their bent over ends it is suflicient for the strength of the hollow pile to form welded seams only at intervals. The invention renders it possible to produce double walls of any desired strength, in which the ratio between moment of resistance and weight of the hollow pile per square meter of wall is much more favorable. Moreover the individual parts can be simply and cheaply rolled. The locking bars lie recessed in the face of the wall. 10
An embodiment of the invention is illustrated, by way of example, in cross section in the only figure of the accompanying drawing.
The hollow pile a is composed of the two U- section outer girders b and U-section web girders c. The flanges of the outer girders b have hook-shaped extensions 11, whereas the flanges e of the web girders, which bear against the hook-shaped extensions 11 of the girders b are thickened in wedge-shape. I-section locking bars serve for the connection with adjacent piles. The girders b, b and c, c forming a hollow pile can be joined by internal or external weld seams to form boxes which can easily be rammed.
Between every two adjacent hollow piles a space 9 is formed which, as well as the space formed by the girders b, b and c, 0 can be filled with concrete orthe like. There is no reason why the flanges of the web girders 0 should not have hook-shaped bent over ends similar to those formed on the girders 1).
Whereas the tightness of the pile a can be attained by the welding seams, the tightness of the space y can be obtained by the concrete or bitumen or the like or by both. It is evident that in this manner an absolutely tight wall can be produced. Furthermore it is possible to produce extremely strong double-walled sheet pilings with any desired moment of resistance 4. and which are moreover very easy to ram. The component parts can be made very easily by rolling.
We claim:--
1. A hollow pile for sheet pilings, comprising in combination two parallel U-section outer girders with their open side directed inwards, two parallel U-shaped web girders with their open side directed outwards, the longitudinal edges of each web girder abutting against one of the longitudinal edges of each outer girder, hooks formed on the longitudinal edges of said outer girders and of said web girders, the hooks on every two abutting edges forming a bead, and I-section locking bars one adapted to engage over each bead to hingedly connect said outer edges of said girders, and of a bent up end on girders to said web girders. the outer edge of the outer girder and a wedge 2. A hollow pile as specified in claim 1, in shaped thickening on the outer edge of the web which the bead formed by two abutting edges girder.
of the outer and web girders consists of an out- WILLEM COENRAAD KOHLER.
