Definitions

  • the invention relates to a drain device for the throttled drain of rainwater according to the generic term of claim 1
  • the building permit authorities require in urban areas of the developers, the rainwater of sealed surfaces on its own grounds seep into let and with this measure the groundwater to enrich and the sewer or sewage treatment plants to relieve.
  • This requirement is not just about water of sealed areas such as squares, but also of Roof surfaces.
  • Rainwater from sealed places like Parking lots and streets must inevitably in the accumulating amount to be derived immediately to one To avoid accumulation.
  • the on roofs falling rainfall due to suitable roofing, especially the flat roofs, or the creation of Reservoir temporarily stored and in the desired Amount be dissipated over a longer period.
  • Rainwater-storing roofs become retention roofs called and they can either be used as nude roofs or as Substrate-covered flat roofs with or without greening be educated.
  • Substrate covered flat roofs can in limited mass in the pores of the substrate temporarily absorb, store and recover water let drain.
  • Known substrates store in their Pores about one third of their own volume. In order therefore To be able to store 50 liters of water per square meter, it needs a substrate volume of about 16 cm in height. The Outflow delay is about five, depending on the substrate structure Hours. After this time, the pores are emptied and that Substrate dries out. In heavy rain, the temporal Absorbent capacity of the substrate often not to the withhold the amount of rainfall. This particular when heavy rainfall on a substrate with already water-saturated Pores fall.
  • the percolation surface should be about 5% of the roof area.
  • a larger retention volume on the roof and a low drainage volume can reduce the seepage area accordingly. This can be reduced, for example, in a detached house with 200m 2 roof area to a 1m 2 .
  • the known throttle devices which allow such low flow rates, require a high level of maintenance, since their dirt and clogging vulnerability of the small diameter of the aperture is very large.
  • Object of the present invention is to provide a Drain device, which has a very small drainage amount per Unit of time, without being affected by suspended matter, Leaves etc. the corresponding small aperture of Drainage device clogged and thus their function can be affected.
  • the inventive Device requires a small cleaning effort, since the cross-sectional area of the upstream filter device is many times greater than the flow rate determining aperture and also optimal Has self-cleaning properties.
  • the filter can manually cleaned if necessary without much effort or be completely exchanged.
  • the drainage device exists from a few individual parts, which are tool-free during assembly can be put together on the roof.
  • the pinhole exists from a pipe, which in the on-site existing, at the roof surface ending drain pipe can be inserted and can be sealed by lip seals.
  • the pinhole only in the drain pipe is inserted, its height or the height of the first row of holes on more if necessary be aligned similar drainage devices, so that at the same time in all drain devices the Water flow starts or larger amounts of water evenly distributed over the drainage devices be derived.
  • an additional pipe put on be, on which a thread is formed, which with a thread on the orifice tube or one above arranged additional threaded pipe combs.
  • the height of the aperture tube by turning the the latter.
  • An over the aperture tube arranged lid which is located at a distance from the upper edge of the diaphragm tube and this projects radially, and one on the aperture tube mounted flange whose diameter with the Diameter of the lid approximately matches be achieved that at the beginning of the overflow no Sucking occurs and also a high suction power is guaranteed.
  • the water inlet openings are arranged in the aperture tube so that they do not diagonally opposite one another at the same height, one becomes significant noise reduction during operation of the Drainage device reached.
  • the pinhole and preferably made of a plastic or a metallic fabric produced filter are covered by an opaque hood, so that no UV light will damage the components and through Incidence of light can promote the growth of algae and moss.
  • the almost complete darkening of the filter area of the Roof drain prevents the rainwater persistent contaminants and dissolved Fertilizers such as ammonia from agriculture, Nitrogen from combustion processes etc. as well as organic Suspended matter such as pollen, pollen etc. none Biorasen Guess or Vermosung form.
  • the production the drainage device can be inexpensive in plastic, Metal or a combination of these materials. Due to the small cross sections of the slits in the hat, which covers the pipe aperture, air circulation the hot air by convection in the drain pipe almost completely prevents, especially if the slits in the hat partially or completely covered by pent-up water.
  • this extended area 7 is a cylindrical in the example Aperture tube 9, at its lower end circumferential Lip seals 11 are arranged and at the top End a plurality of holes or holes 13 preferably in a regular arrangement next- and are embedded on top of each other (see the settlement in Figures 6 and 7).
  • the upper edge of the diaphragm tube 9 is at the height of a3.
  • a carrier 15 Concentric with the diaphragm 9 is a carrier 15, comprising a central ring 17 which extends over only about twenty percent of the section above the roof 1 of the aperture tube 9 extends.
  • the central ring 17 At the central ring 17 are For example, four connecting webs 19 (see FIG. attached, which extend radially outwards and there are connected with ring sections 21.
  • the ring sections 21 extend from the roof surface to the height a3.
  • a support ring 25 This can be connected to the ring sections 21 or in one piece be prepared or put on this.
  • the ring sections 21 and the support ring 25 made in one piece.
  • in the Support ring 25 are a plurality of recesses 27th admitted.
  • the carrier 15 can with a Attachment means 47, e.g. Screw and nut, on Aperture 9 to be attached.
  • a cylindrical Fine filter 23 This is preferably dimensionally stable and consists of a fine metal or plastic grid or braid.
  • the fine filter 23 may be tubular or be made without seam or made of a tubular rectangular lattice piece joined together to form a tube be.
  • the fine filter 23 is two at the top and bottom applied O-rings 29 or a metal strap attached. Alternatively, the attachment of the fine filter 23 also be done with Briden or the like.
  • the tubular fine filter 23 projects beyond the lower O-ring such that it as a flange-like protuberance 24 on the Surface of the roof rests (see Figure 4).
  • a hat 31 This includes one cylindrical or polygonal jacket 33, at the Lower edge of a plurality of vertically extending Slots 35 are recessed.
  • the hat 31 is on top a frusto-conical cover 37 completely closed. Inside the jacket 33 can clamp and Holding means 39 to be formed, which the hat 31 with respect a flange 41 at the upper edge of the support ring 25th center and hold the hat 31.
  • the access of the water takes place always through the slots 35 in the jacket 33 of the hat 31st Through the slots 35 are larger impurities such Leaves and branches withheld. This rough Impurities can be lifted without lifting the hat 31 be eliminated. Finer impurities, such as pollen or leaf sections that just the slots 35 can happen, are stopped at the fine filter 23.
  • Whose Surface is in the example shown about five times big as the surface of the aperture tube 9.
  • the Water level within the roof outlet 3 always corresponds about that outside.
  • the through the fine filter 23rd passed water is free of impurities, which are always larger than the holes 13 in the diaphragm tube. 9 Consequently, the holes 13 always remain continuous and ensure the specified calibrated outflow.
  • a threaded tube 48 attached to the upper end 7 of the drain pipe 5, at which a flange 8 may be fixed, a threaded tube 48 attached.
  • a threaded tube 48 is attached at the lower end of the Threaded tube 48 also a flange 8 'attached, over which secured by means of screws 10, the threaded tube 48 can be.
  • a External thread 50 is formed, with an internal thread a Stülprohres 49 meshes.
  • the upper end of the Stülprohres 49 carries the aperture tube 9, which at its upper edge is surrounded by an outwardly directed flange 55.
  • an external thread and on Threaded tube 48 an inwardly directed thread 50.
  • About the aperture tube 9 with the flange 55 is spaced a Cover 52.
  • the diameter of the lid 52 corresponds to is essential to that of the flange 55 and much larger than the diameter of the aperture tube.
  • Between the lid 52 and the flange 55 results thereby a suction slot 51, through the water at Exceeding the level a3 enter the diaphragm tube 9 can.
  • By turning the lid 52 by suitable Spacer is connected to the flange 55, the Height of the upper edge of the aperture tube 9 (height a3) on and be adjusted.
  • the Holes 13 are arranged in the aperture tube such that the there entering water jets 53 are not in the Center frontally meet, but diagonally opposite to the Wall to be redirected.
  • the holes 13 are therefore offset accordingly on the circumference and / or in height arranged.
  • the level of the withheld Rainwater on the roof 1 always to a minimum Lower and thereby set the fine filter 23 dry.
  • self-cleaning of the Filters 23 instead, leaving this for a long time without mechanical cleaning or replacement fully operational remains.
  • a clogging of the filter occurs 23 never suddenly, but gradually from bottom to bottom above, so that it is visible from the outside, that the accumulation height, as shown for example in Figure 2 with Arrow 45 is indicated on the outside of the hat 31, something rises. If the accumulation height exceeds the specified one essentially, so can by lifting the hat 31 and Removing the O-rings 29 of the fine filter 23 dissolved and either cleaned or replaced.
  • the drain device not only be used on flat roofs, but also in Rainwater collection basin, where rainwater from Steep roofs or non-stowable other areas temporarily withheld and calibrated to one Seepage is to be passed.
