Description
~L039071 The present invention relates to a pile construction and more particularly a metal pile constructed o~ four elon-gated metal members and defining a central solid core with the outer periphery of the pile being constituted by flange sections.
Steel piles constructed from railway rails are known but these all have the disadvantages that when driven into the ground, some of the rails become detached or break by the application of blows from one end of the pile. Repair on site of such breakage is very costly and time consuming. Also, known type piles utilizing railway rails are fabricated in a plant and then transported to a site. The reason for plant fabrication is that their attachment or the position of the rails relative to one another is such that a great deal of ~ -accuracy is required to support the rails in particular posi-tions and to weld them together in that position. Still further, the configuration of piles constructed with railway rails do not have a sufficiently large central core to support a large load nor do they all have sufficient strength in their outer , periphery to withstand the impact of a heavy weight hammer ~ -normally utilized to drive the piles into the ground. ;
It is a feature of the present invention to provide a steel pile constructed of railway rails which substantially overcomes all of the above disadvantages.
It is a further feature of the present invention to provide a pile constructed from railway rails and having a central core constituted by flange sections of the rails and an aggregate of cement.
According to the above features, from a broad aspect, the present invention provides a pile comprising four elongated metal members secured together in elongated parallel abutting i"~"
~'~' relationship. Each of the four elongated metal members has . ~. . ... . .
~039()~
opposed flange sections and an in-terconnecting web extending transversely from mid-width of each opposed flange section. The four elongated metal members are connected to form a central core defined by opposed pairs of a common one of said flange sections, One of the pairs is disposed transverse to the other pair to form the central core, Two opposed parallel pairs of peripheral flange sections are constituted by the other common flange section to provide sufficient strength in the periphery of the pile to resist deformation of the pile by the application of blows thereto and from one end thereof when driven axially into the ground, The invention will now be described with reference to a preferred embodiment as illustrated by the examples shown in the drawings in which:
FIGURE 1 is a cross-section view of a pile constructed in accordance with the present invention, FIGURE 2 is a further cross-section view of a further configuration of a pile constructed in accordance with the present invention, and FIGURE 3 is a still further cross-sectional view of a still further embodiment of the present invention, Referring now to the drawings, and more particularly to Figure 1, there is shown generally at 10, the pile of the present invention and comprising four elongated metal mernbers 11, herein railway rails, which are secured together in longitudinal parallel abutting relationship. Each of the elongated members or rails 11 is provided with opposed flange sections 12 and 13 and an interconnecting web 14 extending transversely from mid-width of each opposed flange section 12 and 13, The four elongated metal members 11 are connected ~ together to form a central core 15 which is defined, in ~..~
., Figure 1, by opposed pairs of common flange sections 13.

. ., ,, ~ .
~ 9~71 As can be seen, each pair of flanges iQ disposed transver~e to one another and aligned ~etween the other pair to form a central hollow core 1~ which is filled with an aggregate of cement 17 after the pile is put in place in the ground.
The opposed parallel pairs of peripheral flange sections 12 lie in the outer periphery of the pile whereby to provide sufficient strength in the periphery of the pile to resist deformation of the pile by the application of ~ ~
blows thereto and from one end of the pile when driven ~ -axially into the ground.
One of the flange sections, namely flange 12, is a ~-substantially flat, plate-like flange having elongated end edges 12'. The other flange 13 is an enlarged flange of ~ .
substantially rectangular cross-section defining an outer substantially flat wall 13', an inner wall 13" connected to the web 11, and opposed end walls 13"'. The elongated metal members 11 are secured together by a weld 18 formed between adjacent end walls 13"' and along the elongated edges adjacent the outer flat wall 13'. The-weld 18 may be a continuous weld throughout the length of the pile or spaced apart spot welds. The configuration of the pile is ~uch as to permit the construction of the pile at the site where it is to be utilized. ;
The pile as shown in Figure 1 is provided with the flat, plate-like flange 12 in the outer periphery of the pile which gives more stability to the pile when driven into the ground~ When it is desired to have a pile with a larger central core, the railway rails 11 are secured to~ether with their plate-like flange 12 surrounding the central core. Such a pile construction is illustrated generally at 20 in Figure 2 Referring to Figure 2, the elongated member~ 11 or railway rails are shown secured in parallel relationship in the same manner as Figure 1 but with their flat, plate-like flange _ ~ _ 1~3s~n71 secured together by a weld 21 formed between adjacent end edges 12'. A further weld 22 may be formed along the outer edges of the outer surface 12" of the flange section 12, thus providing a weld in the hollow core and on the outside.
Of course, the weld 22 cannot be made throughout the length of the pile and such is provided at the ends only.
As hereinshown, the hollow core is much larger than the core of the pile as shown in Figure 1 and this type ~ -of pile is preferred for supporting heavier loads.
10Referring now to Figure 3, there i9 shown generally at 30, a further embodiment of the pile. As herein-shown, the central core 31 is substantially a solid steel core constituted by interconnecting the four enlarged flanges ~`
13 together. To make this pile, the enlarged flange of a first pair of flange sections 13 are connected together, w~th their outer flat wall 13' in juxtaposition, by making a weld 32 bridging the end walls 13"' which lie in parallel opposed common planes. Care is taken that this weld is not too large to interfere with the outer flat wall 13' of the other pair of flange sections secured on these common planes.
The outer wall 13' of each flange of the other pair of flange sect ons is secured in facial contact and centrally aligned with the opposed end walls 13"' of the first pair and connected thereto by welds 33 made ~etween their elongated upper edges of the end walls 13~' and the edge of the inner wall 13" of the first pair, Thus, there is formed a pile having a solid steel core 31 and large plate~like stabilizing flanges 12 lying in the outer periphery and spaced from the central core of the pile.
It is within the ambit of the present invention to provide any obvious modification~ of the configuration of the piles herein disclosed, provided there are four railway rails ~,:
