Definitions

  • the present invention relates to a jack intended to support a raised floor, in particular removable by elements.
  • the object of the present invention is to improve the seat plate in order to allow both, on the one hand, to absorb an excess of adhesive when the base is glued to the ground, and on the other hand share easily tear the same base from the same soil, when you want to remove or move it.
  • the seat plate has hollow and radial ribs, located on the side opposite the bearing ground, forming at their end adjacent to the perimeter of said plate, tearing hook of the base.
  • the support head (5) comprises a tubular sleeve (7), mounted freely and coaxially with respect to the threaded rod (3), and resting at one end (7a) on the adjustment bolt (4).
  • a plate (8) for supporting the elements (6a) to (6d) is mounted at the other end (7b) of the sleeve (7), perpendicular to the axis of the latter, and therefore parallel to the surface d 'support (la), or on the supporting ground (2).
  • the plate (8) is welded by electrical contact with the straight end (7b) of the sleeve (7), determining a plane perpendicular to the axis of the latter, and opposite the end (7a) resting on the adjusting nut (4). Near the axis (9) of the jack, the plate (8) partially seals the end (7b) of the sleeve (7), adjacent to said plate, a residual hole (8b), circular, but of smaller diameter than that of the sleeve (7), being formed in the center of the plate (8).
  • the plate (8) comprises, on the one hand a central part (8a), of radial extension from the axis (9) of the sleeve, reinforced by hollow radial ribs (8g) , having approximately the shape of a square, and on the other hand four wings (8c, 8d, 8e, 8f), crosswise, continuous with the central part (8a).
  • Each wing has vertical edges, directed downward, so that it has a U-shaped cross section.
  • Each wing (8c) to (8f) has a shoulder (8c ') to (8f'), s 'extending parallel to the bearing surface (5a) of the central part (8a) of the plate (8), at a distance substantially corresponding to the thickness (e) of a crosspiece (10).
  • each crosspiece (10) has a transverse U-shaped profile, and therefore comprises a core with two perpendicular wings; the end of such a cross member fits on a wing (8c) to (8f), the wings being in contact with two vertical edges of the plate (8), and of the core resting on a shoulder (8c ' ) to (8f ') as previously defined.
  • the shoulders (8c ') to (8f') make it possible to maintain any bearing surface at the level (5a) of FIG. 1, with respect to the elements or slabs (6) placed after the crosspieces (10) .
  • means (11) for locking in rotation are provided at the end (7a) of the sleeve (7) opposite the plate (8), relative to the adjusting nut (4).
  • These means consist of notches (11a) provided in the thickness of the wall of the sleeve (7), projecting axially from the horizontal plane (7c) of the same end (7).
  • Corresponding notches (11b), therefore hollow, are provided on the surface (4a) of the nut on which the sleeve (7) rests.
  • the support head (5) is locked in rotation, so that in turn the sleeve (7) blocks the nut adjustment (4), which allows over time to maintain the mounting height of the jack, whatever the stresses, for example vibrations, to which the technical floor is subjected.
  • pins such as (8e ") make it possible to position each element or slab (6a) at (6d), two adjacent and perpendicular sides of the same slab bearing against two lugs corresponding, oriented perpendicularly to each other.
  • the base (1) comprises a seat plate (12), of generally square shape, on which a fixing nut (13) is fixed flat. On this nut (13) is screwed in a removable and adjustable manner the end (3b) of the threaded rod (3), opposite the head (5) of support. Like the tube or sleeve (7) relative to the plate (8), the seat plate (12) is welded flat by electrical contact with the fixing nut (13). This allows in particular to obtain a precise positioning of these different parts, relative to each other, without a welded joint, which would interfere with the desired precision of the assembly.
  • the seat plate (12) has radial ribs (12a), in relief, and located on the side opposite the load-bearing floor (2).
  • Each rib (12a) extends radially up to the perimeter of the plate (12), forms at its end (12a '), adjacent to the perimeter of the plate (12), a tearing hook for the base (1 ), when the latter is glued to the load-bearing floor (2).
  • the removability of the threaded rod (3) relative to the fixing nut (13) simplifies the implementation of the cylinders for raised floors. By having threaded rods of different lengths, it is possible to adapt to all the heights required for the raised floor, while keeping the same base and the same support head.
  • the seat plate (12) comprises a clamping hook (12b), obtained by cutting the plate (12), and deformed against a braid or metallic conductor (15) .
  • a clamping hook (12b) obtained by cutting the plate (12), and deformed against a braid or metallic conductor (15) .
  • the bearing surface (5a) can be coated with a thickness of a flexible and elastic material, electrically conductive, making it possible to dampen vibrations, while driving charges to the base.
