Definitions

  • the invention relates to a raised floor with height-adjustable supports that support head plates, with grid support rods made of square tubes, which are anchored to the head plates with their upper wall and extend between the supports, and to floor plates with their corners on the head plates and with their Edge areas are supported on the grid support rods.
  • the invention has for its object to improve the connection of the grid support rods to supports of raised floors from a static point of view so that higher loads can be transferred over the grid support rods and supports compared to the prior art, thereby increasing the load capacity of the raised floor overall.
  • the connection of the grid support rods should be easy to assemble and also be able to be manufactured subsequently.
  • the grid support bars can advantageously be simply placed on the support rings, the support rings also serving to level the base plates in the further course of the installation work.
  • at least the front edges of the lower wall of each grid support bar are positively and / or non-positively connected to a height-adjustable sleeve on the supports, so that the front edges of the lower wall of each grid bar are held in place when the supports are loaded and in this way practically the entire cross section of the grid support bars can be used statically.
  • the head plates are attached, for example screwed, to the upper end of the height-adjustable sleeves, and then, as is known, the grid support rods are attached to the top plates with their upper wall, for example screwed on.
  • the solution according to the invention is thus easy to assemble and can also be used retrospectively even with existing raised floors. Then only the grid support rods and some parts of the existing support have to be replaced, provided that they already have a threaded shaft or a threaded tube on the footplate.
  • the grid support bars can also be dimensioned weaker with the same floor load due to the solution according to the invention. This material saving leads to an overall cheaper solution.
  • grid support bars can be used, the ends of which are simply cut at right angles.
  • FR-PS 2 050 197 also discloses a height-adjustable support for raised floors, in which grid bars with a U-shaped cross-section open at the bottom rest with their end edges on a height-adjustable sleeve of the support.
  • the grid support rods with their upper wall (web) are neither attached to the height-adjustable sleeve, nor to the head plate of the support, but only inserted between a plate-shaped support of the height-adjustable sleeve and fingers protruding outwards on the head plate.
  • Embodiments of the invention emerge from the subclaims. In this way, the introduction of forces from the grid support bars into the supports continues improved if the end edges of the side walls of the grid support rods are positively and / or non-positively connected to the height-adjustable sleeves.
  • the height-adjustable sleeve on each support is completely or partially closed at the top by an end wall, the attachment of the head plates is e.g. facilitated by screws on this end wall, which can also have a ring shape.
  • the support ring for the grid support bars has one or more upwardly projecting anchoring projections for the grid support bars provided with corresponding receiving openings, a simple fixation of the ends of the lower wall of each grid support bar becomes laterally even when the grid support bars are placed on these support rings reached.
  • the anchoring of the grid support rods on the head plates is facilitated or simplified if, according to yet another embodiment of the invention, one or more downwardly projecting anchoring projections are provided on the head plates for the grid support rods provided with corresponding receiving openings. Because these anchoring projections take effect immediately when the head plate is screwed onto one of the height-adjustable sleeves.
  • the support ring is designed as a threaded ring and screwed onto a thread of the tube of the support. This allows you to use an inexpensive height-adjustable sleeve with a smooth inner wall, which is supported on the support ring, which in turn, for example, by another Threaded ring (counter element) can be fixed in its respective setting height.
  • the height-adjustable sleeve it is also possible for the height-adjustable sleeve to be screwed onto the thread of the tube of the support by means of an internal thread and for the support ring for the grid support rods to form the locking element for the sleeve.
  • the support ring designed as a threaded ring.
  • the height-adjustable sleeve and the support ring for the grid support rods are carried by an extension piece of pipe, which is axially displaceably arranged on the pipe of the support and is supported on a threaded ring screwed onto the thread of the pipe, is obtained
  • a column version with a large overall height which is suitable for raised floors that need to be raised accordingly.
  • the support ring for the grid support rods can be attached to the extension tube piece or can be formed in one piece with it.
  • the various embodiments of supports of a double floor described below are each set up in a grid on a raw floor of the building in question and anchored to this, if necessary.
  • Four grid support bars are connected rigidly to each support (except for the wall-side) and the individual floor slabs are laid on the substructure thus formed, with four floor slabs meeting with their corners centrally on a support.
  • the four corners of the floor slabs are supported on the supports and their edge areas on the grid support bars.
  • Figures 1 to 3 show a support 10 with a circular base plate 11 to which a tube 13 is welded in the center, which is provided with an external thread 12 in the upper region.
  • a support ring 14 designed as a threaded ring for the four grid support rods 15 assigned to the support 10 is screwed onto the external thread 12 of the tube 13.
  • Another threaded ring 16 serves (as a counter nut) for fixing the support ring 14 in its respective height position.
