Definitions

  • the invention relates to a sprinkler system for high-bay systems according to the preamble of claim 1.
  • an effective area of 45 m2 or 90 m2 per sprinkler level is used.
  • the height of each sprinkler level must be taken into account.
  • the amount of water for the effective area of the ceiling protection is added to the shelf protection and is included in the calculation for the water supply.
  • high water outputs are necessary due to the large number of shelving levels to be protected. This requires very large supply lines and valve stations, which means that the known sprinkler systems cause high construction costs and high costs.
  • a large amount of extinguishing water must be kept available and high-performance pumps must be used, especially since the entire geodetic height must always be bridged.
  • the object of the present invention is to design a sprinkler system of the type mentioned at the outset in such a way that the outlay for the constructional and apparatus structure is reduced and sprinkler protection and electronic fire alarming are largely ensured even if a valve station fails.
  • the horizontal division into sprinkler groups provided according to the invention divides the required amount of water (effective area x number of intermediate levels) into several groups and accordingly into several valve stations per effective area over all sprinkler levels. By dividing the amount of water, the valve stations and the cross-sections for the supply lines can be selected to be smaller. The entire geodetic height is no longer required for the lower levels of the rack storage to be bridged, so that pumps with lower performance can be used.
  • the sprinkler levels combined in a group can be adapted exactly to the pump characteristic. Due to the horizontal meshing of the extruded pipes and downpipes provided according to the invention, the extruded pipes of the adjacent shelves are used as feed lines to the active surface, so that the feed lines previously used under the ceiling to the downpipes can be saved.
  • the meshing contributes to a high uniformity of the amount of water between the favorable and unfavorable effective area.
  • the non-uniformity can be reduced below 10 percent.
  • the pump output and the amount of extinguishing water to be kept available can be significantly reduced.
  • the horizontal grouping and meshing of the pipe network offers additional security when the sprinklers are triggered in the effective area of a shelf. If a valve station fails, sprinkler protection below and above it and electronic alarming on the shelf are still guaranteed. Not all sprinkler levels on the shelf fail immediately. By meshing the pipe network, the supply of the other sprinklers is guaranteed even after an interruption of a strand pipe.
  • the drawing schematically shows a high-bay system with a plurality of shelves 2 arranged side by side, each having a plurality of shelf levels 4 arranged one above the other.
  • Each shelf level is assigned two sprinkler rows 6, 8 arranged side by side. Depending on the shelf width per shelf level, one to three sprinkler rows are provided in accordance with VdS guidelines in order to achieve the prescribed effective area 9, cf. the figures of the drawing.
  • the sprinklers 11 of each row are located on sprinkler pipes 10, 12, 14.
  • the sprinkler system is horizontally divided into several sprinkler groups 20, 22, 24, 26, which are arranged one above the other in FIG. 1 and three in FIG. 3, such that several, here three sprinkler levels 28, 30, 32 per sprinkler group are summarized.
  • the horizontal division can be from halving all levels to one level per group.
  • the sprinkler pipes 10 to 18 of each sprinkler group are supplied with extinguishing water via the down pipes 34, 36, 38, 39 assigned to each group.
  • the sprinkler pipes and the downpipes are meshed horizontally, cf. Fig. 1 and 2, so that the sprinkler pipes serve as feed lines for the downpipes and thus the usual leads to the downpipes can be dispensed with.
  • the sprinkler groups are supplied with extinguishing water via supply lines 40, 42, 44, 46 and valve stations 48, 50, 52, 54, the extinguishing water being supplied via a pump 44 and a supply line 56 common to all sprinkler groups.
  • 1 and 3 also show the arrangement and supply of ceiling protection sprinklers 58 via their own supply line 60 and their own valve station 62.
