Definitions

  • the invention relates to a foundation arrangement according to the preamble of claim 1 and particularly to a foundation arrangement for a building, wherein one or more pillars of the building are supported to piles placed into the ground, the foundation arrangement comprising a pile array including two or more piles for supporting a pillar.
  • the invention also relates to a method according to the preamble of claim 10 and particularly to a method of accomplishing a foundation of a building, the method comprising placing piles into the ground, one or more pillars of the building being supported to said piles.
  • the foundation of buildings is formed by installing piles into the ground, the piles carrying the loading created by the building see for example GB 2 216 153 A .
  • These piles are installed into the ground in accordance with the load-bearing capacity of the ground and the required loading created by the building in each particular case. Accordingly, the size, number and material of the piles vary in accordance with the circumstances in each particular case.
  • the upper ends of the piles are left to project upwards from the ground surface.
  • the building in turn, comprises substantially vertical pillars that constitute the load-bearing structure of the building in each particular case.
  • the pillars are supported to the piles by casting a so-called concrete sole between the piles and the pillars, to which sole the upper ends of the piles are placed.
  • a so-called concrete sole between the piles and the pillars, to which sole the upper ends of the piles are placed.
  • fastening parts are cast into the concrete sole, to which parts the pillars are further fastened.
  • the pillars may also be supported directly to the piles without making a concrete sole.
  • the object of the invention is thus to provide a foundation arrangement to solve the abovementioned problems.
  • the object of the invention is achieved with a foundation arrangement according to the characterizing part of claim 1.
  • the object of the invention is further achieved with a method according to the characterizing part of claim 10.
  • the invention is based on achieving the foundation of a structure or a building by placing two or more piles constituting a pile array into the ground. Beams extending between the piles are fastened and/or supported horizontally to the piles of the pile array.
  • the pillar of the building is supported and/or fastened to these beams, whereby the loading of the pillar is distributed via the beams to the piles of the pile array.
  • a frame is preferably formed from the beams and installed on top of the piles in such a manner that the beams extend substantially in the horizontal direction.
  • the foundation arrangement comprises a pile array for supporting a pillar, the pile array comprising two or more piles, and one or more beams supported to two or more piles of the pile array, and a pillar supported, in turn, to one or more beams for distributing the loading of the pillar to the piles of the pile array by means of the beams.
  • the pillar may be supported directly onto the beams, the pillar extending upwards from a level defined by the beams, or the pillar may be supported to the beams from the side such that the pillar may extend below the level defined by the beams.
  • the beams may also be replaced with a plate-like structure that is supported to the piles.
  • the plate may be a ready-made concrete plate placed and supported to the piles.
  • the pillar is supported to the piles by means of a substantially horizontally extending beam, beams or plate such that the loading of the pillar is transferred via the beam, beams or plate to the piles of the pile array.
  • a structure is achieved wherein the load generated by the pillar is transferred in the beam or the plate substantially as bending forces to the piles, the vertical load of the pillar being transferred in the substantially horizontally extending beam or plate.
  • An advantage of the method and arrangement of the invention is that, in accordance with the invention, the foundation can be constructed quickly by means of piles and steel structures in such a manner that there is no need to cast a concrete sole at all, or the concrete sole may be cast after the installation of the pillar at a suitable construction stage.
  • casting the concrete sole does not slow down the progress of the construction, since casting a concrete sole is conventionally slow and its drying also takes up time, during which the construction does not advance.
  • the foundation arrangement of the invention allows the foundation phase and the entire construction to be sped up and also a simple and efficient foundation arrangement to be achieved. This foundation arrangement may be permanent or temporary.
  • a temporary one may be used for instance when a concrete sole is additionally achieved in the foundation, whereby there is no need to wait for the concrete sole to be cast and dried, but the construction can be continued immediately after the piling.
  • the temporarily used foundation according to the invention may then be torn down as regards the beams.
  • the pillars may always be placed at the desired location irrespective of the location of the piles.
  • FIG. 1 it shows an embodiment of the present invention, showing a top view of the foundation arrangement of the invention.
  • piles 2 are installed into the ground 50, in this exemplary embodiment four of them, which constitute a pile array.
  • the piles may be for example steel piles, woodpiles, concrete piles, bored piles or any other corresponding piles to which the building or structure is supported.
  • the piles 2 are preferably steel piles having a round cross-section whose diameter may vary between 60 and 1,000 mm, for example, according to the need.
  • the number of piles may thus vary from two upwards according to the need in each particular case.
  • the number and size of piles is particularly affected by the dimensions of the building, the loading caused thereby, and the quality of the ground.
  • the upper ends of the piles 2 of the pile array are preferably flushed for instance by cutting off the piles 2 after the installation into the ground.
  • the upper ends of the piles 2 may also be flushed by some other known method.

  • the beams 5 may be fastened to the beams 4 by welding, mechanically with bolts or by some other suitable method.
  • the beams 5 may be fastened to the sides of the beams 4 such that the beams 4 and 5 are flush, or, similarly, the beams 5 may be installed to be supported on top of the beams 4, such as is shown in Figure 2 , whereby the beams 4 and the beams 5 are on a different level.
  • the beams 4, 5 and/or the frame are installed in the piles 2 preferably in such a manner that the beams 4, 5 extend substantially in the ground plane and horizontally, as Figure 2 shows.
  • the beams 4, 5 may have any cross-section, such as for example H, I, L, T, TT, Z or U beams or flanged U beams or beams having another corresponding cross-section.
  • they may be tubular beams that may have a round, square or another cross-sectional form.
  • the beams may also be massive.
  • the beams 4 and 5 installed in the piles 2 of the pile array may be similar to or different from each other.

  • the concrete sole may be cast after the foundation arrangement built by means of the piles 2, the beams 4, 5 and the pillar 6 is complete. In this case, however, the construction may be continued in spite of the casting of the concrete sole and the drying thereof, since the structure is already supported with the foundation arrangement according to the invention.
  • the concrete sole may be cast in such a manner that, in the case of Figure 2 , the pillar 6 extends inside the concrete sole.
  • Figure 2 shows the concrete sole with a dashed line.
  • the concrete sole may also be used in the solution of Figure 1 , whereby the pillar does not necessarily extend at all up to the concrete sole.
  • shearheads may be used in the piles and/or the pillar extending to the concrete sole, the shearheads preventing the pillar and/or the piles from piercing the concrete sole.
  • shearheads any shearheads according to the known art may be used.
  • the beams 4, 5 may be removed, since the concrete sole provides the pillar with the support required thereby.
