Definitions

  • the pile shoe to be left in the ground can be freely slipped out of the tubular form so that during the removal of the tubular form, it remains in situ in the foundation ground in order to permit that the material intended tobe used to make the pile may pour out of the tubular form.
  • the valve-fitted pile shoe comprises one or more movable members which, while the tubular form is being driven into the ground take a closed position so as to prevent the earth or portions thereof from enter ing the interior of the tubular form, and during the removal of the form they take such a position as to allow the pile-forming material to pour out.
  • valved shoe is formed by a substantially circular swash plate hingedly connected to the interior of the tubular form-in correspon dence with the bottom end thereof so that during progress of the form driving the peripheral portion of the plate may rest on one or more points, or continuously, against the edge of the tubular form so as to prevent the earth from entering thereinto and, during the removal of the form, on account of the eccentricity of its center of gravity with respect to the hinge point, it is rotated downwards thus affording an opening through which the filler material, such as concrete, gravel or sand, is permitted to flow.
  • the filler material such as concrete, gravel or sand
  • Such a kind of valved shoe has, however, the serious drawback that it cannot be opened integrally: as a matter of fact a substantially circular plate hinged at a point ofits circumference in correspondence with the bottom end of a vertical tube and in the interior thereof, cannot be opened completely towards the bottom, thus originating the shortcoming of being compelled to use extremely fluid materials.
  • valved shoe as used today comprises a plurality of members, which are substantially a part of a conical surface, which are hinged at the bottom end of the tubular form and which, during the driving operation, remain united by means of a holding ring which has been freely slipped onto the pointed end, whereas during the withdrawal of the form they are opened since the action of the ground acts in such a way as to slip the ring out of said members and to remain in situ.
  • the principal object of the invention is to provide a form of tubular form having a valved point which is capable of removing or minimizing all the defects enumerated above which impair the conventional pile shoes, while retaining simultaneously all of the advantages thereof.
  • Another object of the invention is to provide a foundation form or tubular form having an extremely reliable, durable and cheap pointed end.
  • a footing form characterized in that it comprises an end tubular portion having a pointed end comprised of two portions, one fixed and the other movable, the fixed portion being integrally formed with said tubular portion, whereas the movable portion is hinged to said tubular portion and can be displaced between an open position where the filler material is allowed to flow, and a closed position where the free end of the movable portion goes to be housed in a rebated portion of a pointed end of the fixed portion.
  • FIG. I is an elevational view showing a footing form made according to the present invention.
  • FIG. 2 is an elevational view showing the same form shown in FIG. 1 but rotated through an angle of degrees with respect to that of FIG. 1.
  • FIGS. 3 to 6 are cross-sectional views taken along the lines III-III, IV-IV, V-V, and VI-VI of FIG. 1, respectively.
  • the form in question is generally shown at I and is structurally composed by a metal tubular portion 2, of which the end portion only has been shown, and by a pointed end 3.
  • the pointed end 3 has a substantially ovoidal cross-sectional outline which gradually tapers from top to bottom (FIGS. 4 and 6) and comprises two portions 4 and 5.
  • the portion 4 is fixed and is integrally formed with the tubular portion 2 and has a solid pointed end 6 (FIG. 6) whereas the portion 5 is movable between a closed and an open position for its being hinged as at 7 to the tubular portion 2; the open position of the portion 5 is shown in FIG. 1 in dotted lines, whereas the closed position is shown in solid lines.
  • the movable portion 5 which is kept closed by the lateral trust of the ground itself or by any suitable conventional means, and the relative hinges, are influenced to a minimum extent only by the shocks and/or vibrations which are transferred axially to the form while the latter is being driven down, these shocks and/or vibrations being nearly completely absorbed by the pointed end 6, the portion 4 and the tubular portion 2, as formed integrally.
  • the portion 5 is opened in the position shown in dotted lines to permit the filler material to pour out, the latter following, on account of the form structure, an axial route so that it can be even not too fluid without causing any trouble thereby.
  • the comparatively acuminate shape of the form according to the invention permits its use in very compact grounds where the conventional forms could not be used without a preliminary drilling of the ground, which, obviously, is much objectionable from an economical standpoint.
  • a footing form for casting foundation piles directly in the ground comprising: an end tubular portion with an acuminate end consisting of two portions, one fixed and the other movable, said fixed portion being formed integrally with said tubular portion and being provided with a pointed end having a rebate forming a seat,
