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 supporting grate In a known base plate of this type, the supporting grate consists of a group of mutually spaced square tubes which are welded with their ends to two transverse square tubes of the same type.
  • the cover plate In this floor plate construction, the cover plate is perforated in strips only in zones, in the areas which coincide with the cavities between the square bars of the grate.
  • the non-perforated part of the cover plate of this known base plate therefore comprises a peripheral edge zone, as well as a number of parallel strips over the square tubes of the supporting grate. In this way, only about 60% of the base area of the plate is used for the passage of air or, in other words, the supporting grate blocks about 40% of the base area of the cover plate for the passage of air.
  • a floor plate for double floors in ventilated rooms which has a supporting grate on which a perforated cover plate is attached.
  • This cover plate is perforated practically evenly over its entire base area.
  • the supporting grate is formed by profile bars with a narrow web-shaped section. These web-shaped sections of the profiled bars are arranged on the cover plate perpendicular to the cover plate only at their zones of full cross-section between the perforations and are formed in one piece with the cover plate.
  • 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 perforations can be provided in the legs and / or in the base section of the U-shaped hollow profile bars.
  • the hollow profile bars can have a V-shaped cross section and the perforations can be arranged in both legs of the V-shaped hollow profile bars.
  • the perforations in the base section of the U-shaped hollow profile bars can be the perforations in the Correspond to cover plates and be aligned with them This measure 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. These supports are set up on the bare floor of the clean room concerned.
  • the raised floors produced from the floor slabs 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 down 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 attached to the zones of full cross section of the cover plate 12, except for the free edges of the inner legs 15 of the two transverse hollow profile bars 14 (FIGS. 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.
