Definitions

  • the invention relates to a roof drainage device with cover for use on flat roofs.
  • Roof drainage devices usually exist from a funnel-shaped inlet and one attached to it connecting pipe socket.
  • the enema is in the Roof inserted and the pipe socket to a drain pipe connected. So that the pipe system does not become dirty, the inlet openings are usually protected, Various designs are known.
  • EP 0 146 561 B1 is a roof drain with a grille known, the a plate covering the inlet having.
  • the plate is at a vertical distance from Arranged roof level and thus forms an open all around Inlet opening, in which an out essentially triangular ribs existing inlet grille.
  • the inlet grille protrudes vertically from the plate, so that if the outside of the inlet grille is clogged, the water climbs over the inlet grille and at the plate edge can flow past into the inlet opening.
  • the device has one relatively large height and in the case of heavy water a cavitation space is formed below the plate, that is not filled with water and in which one Vacuum forms. This will make the flow impaired.
  • the invention has for its object a roof drainage device with improved drainage behavior to accomplish.
  • the roof drainage device a covering device that consists of a trough-shaped Plate with bottom opening and a plate trough there is essentially a covering cover, the plate trough in a funnel part of an inlet funnel of the roof drainage device.
  • the funnel part opens into a pipe socket to which a drain pipe is connected.
  • the inlet opening is from the outer edge of the plate and the Inlet funnel formed.
  • the underside of the plate trough is preferably and the top of the funnel part parallel to each other educated.
  • the circumference of the lid and the upper edge of the plate trough an overflow opening.
  • the inlet opening is dirty Water through the overflow opening, so that also in in these cases, water drainage is guaranteed.
  • Rainwater washed up on the roof Foliage or other dirt can accumulate in the ring Fix the inlet opening and so the water accumulate. The water then no longer flows through you from the bottom of the plate and the top of the funnel part formed channel, but through the Overflow opening and the bottom opening of the plate.
  • a strong negative pressure is built up in the channel. This Pressure is sufficient to clear the foliage from the inlet opening suck away.
  • the roof drainage device is thus self-cleaning.
  • the upper diameter of the plate trough three to four times the diameter of the pipe socket. With this ratio the water is on a long enough Route channeled so that an even flow arises.
  • the lid is preferably in the plane of the plate rim arranged. This allows the construction of the roof drainage device be kept very flat and the risk of constipation is reduced.
  • the cross-sectional area of the pipe socket essentially the inlet cross-section of the inlet opening. So are the drainage rates of the inlet opening and pipe socket almost the same. This guarantees a very even Flow of water.
  • Fig. 1 shows a cross section of a roof drainage device 1 for a flat roof consisting of one Inlet funnel 2 and a cover device 3.
  • a roof drainage device 1 for a flat roof consisting of one Inlet funnel 2 and a cover device 3.
  • In Flat roofs usually made of concrete, are Openings exist in which an inlet funnel 2 is inserted which is e.g. made of plastic is shaped. Then the roof is covered with a skin 20 covered, which leads into the inlet funnel 2 becomes.
  • the cover 3 is through here Supports, not shown, hovering above the inlet funnel 2 held.
  • the inlet funnel 2 has a funnel part 4 and an adjoining pipe socket 5. At the The upper edge of the funnel part 4 goes into one the horizontal surface flush with the roof.
  • the Cover device 3 consists of a trough-shaped Plate 6 and a lid 7.
  • the plate 6 has one Plate 8 on a plate trough 9 with a central Bottom opening 10 encloses.
  • the plate 6 dips about up to half of the funnel part 4 in this.
  • the outer edge of the plate edge 8 and the top of the Inlet funnel 2 and the roof skin 20 form a annular vertical inlet opening 11 on the circumference of the Roof drainage device 1.
  • the channel 12 has a uniform Height a from 10 to 20 mm.
  • the lid 7 has a diameter which is slightly smaller than the top diameter the plate trough 9 and is with radially projecting supports placed on the upper edge of the trough 9, see above that between the supports several overflow openings 13th be formed.
  • the pipe socket 5 has a nominal inside diameter of 70 mm. All other dimensions of the roof drainage device 1 depend on this measure, since the drainage performance the roof drainage device 1 of the drainage capacity the drain pipe is adjusted.
  • the depth of the Funnel part 4 is 30 mm and the upper diameter 250 mm.
  • the plate 6 has a diameter of 350 mm, the upper diameter of the plate trough 9 that of Funnel part 4 corresponds.
  • the diameter of the bottom opening 10 is equal to that of the pipe socket 5.
  • the water flows through the inlet opening 11 and is from the channel 12 in the pipe socket 5 and a drain pipe connected to it.
  • the height a of the channel 12 is over the entire radial extent essentially constant.
  • On the pipe socket 5 creates a downward pull that strives is to suck air into the pipe socket 5.
  • pressure equalization takes place with the environment instead. Without this pressure equalization form a cavitation space above the pipe socket 5.
  • a steady continuous flow would be not realizable.
  • the attached above the pipe socket 5 Cover 7 prevents dirt in the pipe socket 5 falls or that too much air is sucked in. A small amount flows through the overflow openings 13 Air sucked in that is sufficient to prevent a vacuum.
  • the water builds up on the flat roof and then flows beyond the plate 8 in the overflow openings 13 and thence through the trough 9 and the bottom opening 10 in the pipe socket 5.
  • the overflow openings 13 are now filled with water, so that no more pressure equalization takes place.
  • the one located in the channel 12 Air sucked out of the flow, so that in the Channel 12 forms a vacuum that removes the dirt from the Inlet opening 11 pulls into the pipe socket 5, and thus makes the inlet opening 11 usable again.
