Definitions

  • the present invention relates to a pedestal for supporting an elevated floor assembly on a substantially flat surface.
  • Such pedestals include a column, a supporting head fixed to the upper end of the column, so as to be capable of supporting the elevated floor assembly, and a base plate fixed to the lower end of the column for providing a support platform for the pedestal.
  • the length of the column is generally adjustable, so that the height of the pedestal can be adjusted.
  • all the supporting parts of the pedestal are generally made of metal, most often steel.
  • German utility model DE-U-94 21 324 discloses such a pedestal, wherein the supporting head and/or the base plate of the pedestal has a socket with a cavity therein, projecting from the side of the base plate facing the column. The lower end of the column is received in the cavity.
  • the base plate is obtained from a metal sheet by a process of deep drawing, wherein a cup like depression is worked in the centre of the side of the base plate facing the column so as to form the cavity surrounded by a collar. This allows for an easy and effortless connection of the column to the base plate, mechanical rigidity of the pedestal is however not guaranteed.
  • a technical problem underlying the present invention is to provide a pedestal for an elevated floor assembly that is less expensive to manufacture and warrants nevertheless a high mechanical rigidity. This problem is solved by a pedestal as claimed in claim 1.
  • a pedestal in accordance with the present invention includes a column, a supporting head fixed to the upper end of the column, so as to be capable of supporting the elevated floor assembly, and a base plate fixed to the lower end of the column for providing a support platform for the column on the surface.
  • the base plate has an underside facing the surface on which the pedestal is to be supported and an opposite upper side facing the elevated floor assembly.
  • a socket projecting from the upper side has a cavity therein, and the lower end of the column is received in this cavity. Reinforcing braces are radially arranged around the socket.
  • a pedestal in accordance with the present invention distinguishes over prior art pedestals in that it is obtained from a metal sheet by a process of deep drawing.
  • a cup like depression is worked in the center of the upper side of the plate, so as to form the cavity surrounded by a collar, and cuneiform depressions are worked in the upper side of the collar, so that the undersides of the cuneiform depressions form substantially flat cuneiform support surfaces of the base plate.
  • These cuneiform depressions are separated by radially extending U-shaped loops of the metal sheet, which form the reinforcing braces.
  • the lower end of the column is advantageously press fit into the cup like depression, so that no screwing, riveting or welding is necessary for fixing the base plate to the column. It will be appreciated in this context that the above described features of the base plate warrant a very solid and stable mechanical fit of the column in the base plate.
  • the underside of the cup like depression forms an additional, substantially flat support surface in the centre of the base plate and contributes thereby to a still better stability of the pedestal.
  • the height of the U-shaped loops linearly diminishes from the rim of the cavity, where they have a height substantially equal to the depth of the cavity, to the rim of the collar, where they have a height substantially equal to zero.
  • the braces formed by the U-shaped loops have in a side view the form of a rectangular triangle.
  • the collar of the base plate has a rim which is preferably substantially flat.
  • the depth of the cup like depression is preferably about the same as its diameter.
  • the column comprises a threaded rod, a bearing nut screwed on the threaded rod and a support tube.
  • a first end of the support tube is placed over a first end of the threaded rod and supported thereon by the bearing nut.
  • the second end of the support tube is fixed to the supporting head, whereas the second end of the threaded rod is axially received within the cup like depression in the centre of the base plate.
  • the base plate is preferably square shaped and has at least six cuneiform depressions separated by six reinforcing braces.
  • FIG. 1 shows a pedestal 10 in accordance with the present invention, which is mounted on a surface 12 to support thereon an elevated floor assembly, of which only a single panel stringer 14 is shown.
  • the pedestal 10 comprises a column, which is globally identified with reference number 16, a supporting head 17 fixed to the upper end of the column 16, and a base plate 18 fixed to the lower end of the column 16.
  • the column 16 consists of a threaded rod 20, a bearing nut 22 screwed on the threaded rod 20 and a hollow support tube 24. The lower end of the support tube 24 is placed over the upper end of the threaded rod 20 and supported thereon by the bearing nut 22.
  • the support tube 24 can be raised or lowered by screwing the bearing nut 22 on the threaded rod 20, so that the height of the pedestal can be freely adjusted.
  • the upper end of the support tube 24 is welded to the supporting head 17.
  • the latter includes normally four or eight supporting arms to which the panel stringers 14 are screwed. On Figure 1 only two supporting arms 26, 28 are seen.
  • the floor panels are not shown on Figure 1. They rest on the panel stringers 14.
  • the lower end of the tube 24 is crimped to have peripheral indentations 30 co-operating with protrusions 32 on the nut 22.
  • crimping of the lower end of the support tube 24 is not only an inexpensive method to provide a high number of equally spaced peripheral indentations 30 to be engaged by the protrusions 32, thus providing a high degree of height adjustment flexibility, but it improves rigidity and axial stability of the support tube 24 and minimises axial play between the support tube and the threaded rod 20 too.
  • This base plate 18 is obtained by a process of deep drawing from a metal sheet.
  • a cup like depression 34 is worked in the center of the upper side of the square shaped plate, so as to form a central cavity surrounded by a peripheral collar.
  • the depth of the central depression 34 is about the same as its diameter.
  • Six cuneiform depressions 36 1 ... 36 6 are worked in the upper side of the collar, so that the undersides of the cuneiform depressions 36 1 ... 36 6 form substantially flat cuneiform support surfaces 38 1 ... 38 6 of the base plate 18.
  • Figure 4 shows a longitudinal section through the cuneiform depressions 36 3 and 36 6 defining the support surfaces 38 3 and 38 6 .
  • An additional support surface 38 7 is formed in the centre of the base plate by the underside of the cup like depression 34.
  • the cuneiform depressions 36 1 ... 36 6 are separated by upstanding U-shaped loops 40 1 ... 40 6 of the metal sheet, which extend radially from the central cup 34 to the border of the plate.
  • Figure 5 shows a cross-section through the loop 40 1 , which is separating the cuneiform depressions 36 3 and 36 4 from one another.
  • Figure 3 shows a longitudinal section through U-shaped loops 40 1 and 40 4 , whereas an elevation of U-shaped loops 40 3 and 40 5 is seen on Figure 4.
  • the U-shaped loops 40 1 ... 40 6 have the effect of reinforcing braces of a central socket in which the cavity 34 is located. Each of these reinforcing braces has the form of a rectangular triangle in a side view.
  • the lower end of the rod 20 is press fit into the cup like depression 34 of the base plate 18, so that no screwing, riveting or welding is necessary for fixing the base plate 18 to the column 16. It will be appreciated that the special design of the bases plate 18 warrants an especially strong mechanical connection between the base plate 18 and the column 16.
  • the cuneiform depressions 36 1 ... 36 6 are arranged so that the metal sheet is doubled in their apex.
  • the apexes of the cuneiform depressions 36 1 ... 36 6 form vertical reinforcements 46 arranged around the cup 34 receiving the lower end of the rod 20.
  • the base plate 18 is preferably a square shaped plate with holes 48 in the four corners for screwing the base plate 18 to the surface 12.
  • the size of the square shaped plate may for example be about 100 x 100 mm and its wall thickness about 2 mm.
