Definitions

  • the invention relates to a plate for raised floors in which load-bearing, square floor plates are placed on vertical, adjustable supports with support plates at the upper end.
  • Such double floors are known in many variants and generally serve as installation floors in which installation lines are laid below the raised floor plates. Closed panels are usually laid with a carpet on the top. If, however, the floor has to be ventilated from below and / or vehicles have to be driven on in highly stressed areas, it is customary to design the plates to be placed as gratings. Such gratings, however, have a relatively large grid spacing and can only take loads of up to a certain size.
  • the present invention is therefore based on the object to provide a plate for such a raised floor, which can be flowed through freely from below and which can also withstand the highest loads of at least 500 kg per plate, the plate size generally 600 x 600 mm is.
  • each Plate consists of several, approximately spaced, approximately C-shaped metal profiles, which are open on the underside and have parallel, transverse cutouts on the top and are clamped together by means of transversely inserted bolts.
  • the bolts are provided with sleeve-shaped spacers each having the length of a profile width and a profile spacing, and the profiles on both long sides are provided with aligned bores, one of which has the diameter of the bolt and the other of which Have outer diameter of the sleeve.
  • the spacer sleeves can then be arranged in such a way that they abut with their one end face on the inner surface of a longitudinal side of the profile, penetrate the other longitudinal side of the profile and rest with their other end face on the outer surface of the adjacent profile.
  • spacer sleeves are arranged so that their ends always meet on both sides of a longitudinal side of the profile, so that the profiles themselves are not compressed and thus deformed.
  • an outer sleeve has the length of a profile width minus a wall thickness and is provided with an internal thread into which the free end of the rest Profile penetrating bolt is screwed.
  • a locking bolt can then be screwed into the free outside of this threaded sleeve.
  • each plate 1 consists, for example, of 21 parallel and spaced-apart profiles 2 which are connected and braced by three transverse bolts 3.
  • each profile 2 has an approximately C-shaped cross section with parallel side surfaces 4 and 5 and is open from the bottom in the form of a wide gap 6.
  • cutouts 7 running parallel to one another and transversely are provided, between which closed areas 8 then lie.
  • the total area of the cut-out areas 7 of each profile 2 corresponds approximately to the area of the free gap 6 on the underside, so that a uniformly free passage of air through the individual profiles 2 can thus take place.
  • Each profile 2 has on the two long sides 4 and 5 mutually aligned bores 11 and 12, the bore 11 in the long side 5 having a diameter which is slightly larger than the outside diameter of the bolt 3.
  • the bore 12 in the other long side 4 has a larger diameter corresponding to the outer diameter of the spacer sleeve 10, these sleeves 10 having a length that corresponds to the width of a profile 2 minus a wall thickness of a long side 5 plus the distance between two profiles 2.
  • the sleeves 10 pushed onto the bolts 3 are now arranged so that they rest with their one end face 15 on the inner surface of one long side 5, penetrate the other long side 4 and hit with their other end face 16 against the outer surface of the long side 5 of the following profile 2 .
  • Such a design and arrangement of the spacer sleeves 10 has the advantage that these sleeves 10 are not only in the free area between two adjacent profiles 2 and thus can compress the profiles with a lateral pressure, but that these sleeves are each on the inside and outside abut a side surface 5 of a profile 2 and thus lie rigidly against one another.
  • the bracing of the profiles 2 against each other over the entire width of a plate 1 now takes place in that the sleeve 20 in the outer profile 2 'on the left side has only the length of a profile width minus a wall thickness and is provided with an internal thread.
  • the bolt head 21 of the remaining profile 2 penetrating bolt 3 is also provided with a thread and is screwed into the outer sleeve 20 until a firm tension between the bolt head 3 and the outer profile 2 'is reached.
  • a plate for a raised floor which can withstand the highest loads and which has a large free cross section for the flow of air.
  • a plate can be assembled easily and quickly from only a few different individual parts, which gives great flexibility.
