IRON FILE A Filed Feb. 16', 1952 d c Q i s n J l- M Inventor: -Bea/(ex Patented Aug. 6, 1935 PATENT OFFICE IRON PILE Enno Becker, Bremen; Germany, assignor to firm Vereinigte Stahlwerke Aktiengesellschaft,
Dusseldorf, Germany Application February 16, 1932, Serial No. 593,346 In Germany February 23, 1931 I Claims.
Recently iron piles havebeen used either as individual piles for the carrying of building construction or as sheet-piling. In these cases piles of I shaped cross-section are preferred, owing to the easier pile driving work. Their carrying capacity depends in the first instance on the friction offered by its large surface. It is therefore desirable to make use also of the carrying capacity of the ground. If the point of the pile were provided with a pile shoe, as one may be inclined to do, then such a pile could be used only in soft ground, and moreover one would gain no advantage over the known kinds of ferroconcrete or hollow piles. Moreover that which would be gained by loading the ground would again be annulled, to reat extent, by the decrease in friction.
The primary object of the present invention is to utilize without substantially affecting the driving work, or decreasing the friction, the carrying capacity of the ground and this is effected by providing a pile-shoe at any desired position of the pile not at the point, so that the pile thereby receives a kind of thickening between the pile point and the pile head. The thickening may be provided at any distance from the pile point.
In most cases it is placed as far from the point,
that the thickening need be driven in only a small distance into the ground.
The thickening may be arranged symmetrically about the pile, however according to the construction of the pile, it may be arranged at different heights and planes above one another. In this way it is easy to apply the invention according to prevailing conditions. This has the further advantage that the thickening which may be of any length and cross-section may be provided even at the building place, for example, by welding, so that it is possible to make it suit in all cases.
The application of the invention to iron sheet piling has the advantage that it permits the carrying capacity of the sheet-piling to be increased, and on the other hand that by suitably shaping the thickening, the iron is prevented from assuming an inclined position during the driving. The piles may also be provided with locking means, so that a closed sheet pile may be obtained.
The thickening may be provided on each individual iron sheet pile of the sheet pile transversely to the axis of the wall, however it may be regularly or irregularly distributed in the case of separate irons of the wall.
Certain embodiments of the invention are illus- (orsi-gso) I I trated inthe accompanying drawing and the same will now be described, reference being made to the accompanying drawing, wherein:-
Figure l is a side elevation of a pile in accordance with the invention.
Figure 2 is a cross sectional plan of the same taken on the line 22 of Figure 1.
Figure 3 is a side elevation of a similar pile to that of Figures 1 and 2 except that additional thickenings are provided at a higher level.
Figure 4 is a side elevation'of the same looking from the left or right of Figure 3.
Figure 5 is a side elevation of a sheet pile structure in accordance with the invention.
Figure 6 is a vertical section of the same taken on line 65 of Figure 5.
Figure 7 is a horizontal section of the same taken on line 1-1 of Figure 5. 7
Referring to Figures 1 and 2 the pile consists of an I sectioniron a provided, approximately in the middle, with thickening elements I) of shoe formation made of sheet iron and connected on either side of the centre web by welding. These thickenings may be either filled up or hollow.
In Figures 3 and 4 the iron 0 is similar to the iron a of Figures 1 and 2 and the thickening elements d are similar to those b of Figures 1 and 2. The arrangement differs from that of Figures 1 and 2 in that additional thickening elements e are secured at a different height from the elements at and are arranged in a different plane, being welded to the outer surfaces of the two flanges of the iron 0.
Figures 5, 6 and 7 illustrate a sheet pile structure in which a number of sheets of Z section (but in which all the angles are right angles) are combined together in pairs so that each pair forms a rectangular trough with flanges projecting at right angles from its edges. Secured in the trough cavity of each pair as shown is a thickening element 9. The several pairs are then driven into the ground side by side as best shown in Figure '7. It will be seen that the carrying capacity of the sheet pile is considerably increased without the driving work being substantially affected.
What I claim and desire to secure by Letters Patent is:-
1. An iron pile comprising a main portion of I-section including a central web and two sheet iron elements of shoe formation secured on opposite sides of the center Web of said main portion at such a distance from the pile point as to lie when the pile is driven with its upper edge at I-section including a central web and two flanges and two sheet iron elements of shoe formation secured respectively on the outer surfaces of the two flanges of said main portion, and two other sheet iron elements of shoe formation secured. respectively on the opposite sides of the center web of said main portion, the first and last named elements being located at such distances from the pile point as to lie when the pile is driven near the upper limit of the ground having carrying capacity.
4. In an iron pile, the location of a plurality of relatively short thickenings of shoe-like formation at opposite sides of the pile section and in each case at such a distance from the pile point that they lie, when the pile is driven, at the upper limit of that layer of the ground which has carrying capacity, while the part ofv the pile between the pile point and the said thickenings is of normal thickness.
5. In an iron pile, the provision of two pairs of relatively short thickenings of shoe-like formation, the thickenings of each pair lying on opposite sides of the pile and the said pairs lying in different vertical planes and somewhat difierent in height, the said pairs of thickenings being located in each case at such distances from the pile point that they lie, when the pile is driven, at the upper limit of that layer of the ground which has carrying capacity, while the part of the pile between the pile point and the said 20 thickenings is of normal thickness.
