Definitions

  • the invention relates to a metal foundation pile for forming a foundation for a building structure, which pile is to be driven into the earth, in particular by means of a vibrator.
  • the foundation pile according to the invention is composed of a plurality of parallel metal bars, which are interconnected by means 'of metal cross-members.
  • the required cross-section of the foundation pile is distributed over a plurality of bars, which are interconnected by means of crossmembers, so that the foundation pile itself as well as the single bars obtain a rigidity which is such, that no buckling will occur, when the maximum strength blow of the vibrator and thus the total vibrator weight is applied to the top of the bars, or even when a downwardly directed tensile force is exerted on the vibrator.
  • each bar consists of at least one rolled billet with a rectangular cross-section.
  • unfinished products are used as bars, which leads to a substantial decrease of the costs of the foundation pile.
  • the mill scale of the rolled billets will give some protection against corrosion, and a further corrosion resistant layer may be applied at low costs due to the favorable ratio between the outer surface area and the cross-section of the billets. Due to this favorable ratio between the outer surface and the cross-section, a downwardly directed force of friction on the foundation pile, which may sometimes occur, is considerably reduced.
  • the rolled billets have a maximum crosssection of X 10 cm*, as such cross-section still allows the foundation pile to be vibrated into the earth without any difficulty.
  • the foundation piles according to the invention may have a very great length.
  • a plurality of rolled billets are positioned one above the other and are coupled by means of intermediate coupling members.
  • FIG. 1 is a front view of a first embodiment of the foundation pile according to the invention.
  • FIG. 2 is a cross-section along the line IIII in FIG. 1.
  • FIG. 3 is a top view of the foundation pile according to FIG. 1, wherein the pile shoe is omitted.
  • FIG. 4 is a front view of a modified embodiment of the foundation pile according to the invention.
  • FIG. 5 is a cross-section along the line VV in FIG. 4.
  • FIG. 1 shows a first embodiment of the metal foundation pile according to the invention.
  • This foundation pile is composed of three parallel metal bars 1 of square cross-section. These bars 1 form the edges of an imaginary triangular prism and are interconnected by means of cross-strips 2.
  • the cross-strips 2 are placed at different levels in the longitudinal direction of the foundation pile.
  • the cross-strips 2 are welded at their end portions to the respective bars 1.
  • the distance between successive cross-strips 2, which interconnect the same two bars 1, amounts to l 2 m in the lower portion of the foundation pile, but may be considerably larger, e.g. 5 m, in the upper portion of the foundation pile.
  • a common pile shoe 3 is mounted underneath the bars 1.
  • This pile shoe 3 has the shape of a grid and is welded to the three bars 1.
  • the three interconnected bars 1, together with the underlying pile shoe 3, are vibrated into the earth, during which operation no danger of buckling exists despite the small cross-section of the bars 1.
  • the metal foundation pile shown in FIGS. 4 and 5 differs from the foundation pile according to the FIGS. 1 3 in that a separate pile shoe 4 is mounted underneath each bar 1. These pile shoes 4 again have the shape of a grid.
  • the foundation pile may be built up of a plurality of elements, which are positioned one above the other and are coupled with each other.
  • Each of these elements consists of a plurality of parallel metal bars 1, which are interconnected by metal cross-strips 2.
  • An important advantage of the foundation pile according to the invention consists in that only a slight earth displacement is necessary when the pile is driven into the earth. This enables the mutual distance between the piles to be much smaller than would be possible when solid piles with the same bearing capacity are used.
  • the mutual pile distance may, for instance, be cm when foundation piles according to the invention are employed, while this distance would be cm when solid piles are used. This is of particular importance in the foundations of tall building structures such as factory chimneys, when a large number of foundation piles has to be driven into the earth close to one another.
  • the foundation pile according to the invention may also be applied as a tensile pile.
  • the foundation pile and the pile shoe, and successive elements of the foundation pile when the same is composed of a plurality of elements positioned one above the other, have to be rigidly interconnected.
  • each bar consists of at least one rolled billet with a rectangular cross-section. As this material may be obtained at a low price, the costs of the foundation pile are considerably decreased.
  • a metal foundation pile comprising; a plurality of spaced upright parallel metal bars, a plurality of horizontally extending elongated metallic cross-members interconnecting said metal bars, said crossmember each having end portions welded to two adjacent ones of said metal bars and being vertically spaced from each other, and a plurality of pile shoes separate from each other, each said pile shoe being fastened to the bottom of a respective one of said metal bars, each said pile shoe being of an essentially gridshaped configuration.
  • each bar consists of a rolled billet with a rectangular cross-section.
  • a metal foundation pile comprising; a plurality of spaced upright parallel metal bars, a plurality of horizontally extending elongated metallic cross-members fixedly interconnecting said metal bars, said crossmembers each having end portions welded to two adjacent ones of said metal bars and being vertically spaced from each other along the length of the bars to prevent buckling of said bars due to application of load thereto for driving the pile into the earth, and a common pile shoe fastened to the bottoms of said metal bars to initiate penetration into the earth due to application of load at the top of the pile, said cross-members being driven with said bars into the earth, said pile shoe being of an essentially grid-shaped configuration.
  • each bar consists of a rolled billet of rectangular crosssection.
