Definitions

  • the invention relates to a floor plate for raised floors in ventilated rooms, in particular clean rooms, with a load-bearing grate on which a perforated cover plate is fastened.
  • the invention has for its object to develop a base plate of the type described in such a way that the shortcomings indicated above are eliminated and a practically uniform air passage over the entire base of the base plate or the raised floor made from such base plates is achieved, and this with minimization of Turbulence over the raised floor.
  • the hollow profile bars can have a substantially U-shaped cross section and the perforations can be provided in the legs and / or in the base section of the U-shaped hollow profile bars.
  • the embodiment of the invention according to claim brings a further improvement in the air flow.
  • the double floor plate 10 shown in FIG. 1 from below has a load-bearing grate 11 for a cover plate 12, which is practically uniformly perforated over its entire base area or with elongated holes 13.
  • a raised floor numerous raised floor panels 10 are supported with their edges abutting one another on a supporting grid made of profiled bars, which in turn rests on height-adjustable supports.
  • the raised floor panels 10 can also be directly supported with their corners on the supports.
  • the supports are set up on the bare floor of the clean room concerned.
  • the raised floors produced from the floor panels 10 according to the invention are designed in particular for clean rooms which are ventilated from the ceiling, the air supplied being able to flow downward over the raised floor into the space below the raised floor.
  • the cover plate 12 but also the hollow profile bars 14, 14a, 14b or 14c of the supporting grids are perforated, as follows will be explained in detail.
  • the grate 11 in the exemplary embodiment according to FIGS. 1-3 has a family of laterally evenly spaced hollow profile bars 14 with a substantially U-shaped cross section. These hollow profile bars 14 are welded at their ends to the aforementioned grate 11 with two transverse hollow profile bars 14 of the same type.
  • the grates with the hollow profile bars 14a - 14c (Fig. 7-9) are constructed in the same way as described above.
  • the hollow profile bars 14 preferably have the same perforations or elongated holes 13 in their two legs 15 as the cover plate 12. It is also important that the free edges of the legs 15 of the hollow profile bars 14 are only fastened to the zones of full cross section of the cover plate 12, except only the free edges of the inner legs 15 of the two transverse hollow profile bars 14 (Fig. 1 and 3).
  • the perforations or elongated holes 13 are provided in the cover plate 13 and in the base section 16 of the U-shaped hollow profile bars 14a, while in the exemplary embodiment according to FIG. 8 the perforations or elongated holes 13 are provided both in the two legs 15 and are worked out in the base section 16 of each U-shaped hollow profile bar 14b of the grate in question.
  • the load-bearing grate in the embodiment according to FIG. 9 is composed of hollow profile bars 14c with a V-shaped cross section, the perforations or elongated holes 13 being provided in both legs of each hollow profile bar 14c.
  • FIGS. 11 and 13 shown in FIGS Raised floor plate also have the cover plate 12 provided with elongated holes 13 according to FIG. 3, for which a load-bearing grate made of flat bars 17 or 17 'is provided.
  • the numerous flat bars 17 which are mutually equally spaced are connected at their ends by welded flat bars 18 which have a lower overall height than the flat bars 17.
  • the overall height of all flat bars 17 ' is the same, that is to say that of the two transverse flat bars 17' at the ends of the coulter of flat bars 17 'which are evenly spaced from one another.
  • the flat bars 17 and 17 ' are so narrow and spaced apart from one another that they can be fastened to the cover plate 12 at its zones of full cross-section between the elongated holes 13. That is, that the free cross section of adjacent elongated holes 13 is not restricted by the flat bars 17 or 17 '.
  • the supporting grate for the perforated cover plate 12 has a family of laterally uniformly spaced profile bars 19 with an L-shaped cross section, which can be connected at their ends by welded narrow flat bars 20.
  • a web-shaped section 21 of the profiled bars 19 is in each case fastened to a zone of full cross section of the cover plate 12 perpendicular to the latter, as can be clearly seen from FIG. 10.
  • the variant of a double floor plate shown in FIG. 12 contains a supporting grate for the cover plate 12, which contains numerous profile bars 22 arranged at the same mutual distance, each with an inverted T-shaped cross section.
  • the profile bars 22 may z. B. by narrow flat bars 23 to the mentioned supporting grid for the cover plate 12 may be connected.
  • the web-shaped sections 24 of the profiled bars 22 are fastened to the cover plate 12 perpendicularly to the cover plate 12 only at the zones of its full cross section between the elongated holes 13.
  • the grates of the embodiments according to the Fi. 10-13 can also be placed with their corners on height-adjustable footrests, not shown.
  • the perforations in the cover plate 12 or in the hollow profile bars 14, 14a-14c consist of elongated holes 13, these can also have any other cross-sectional shapes.
