Definitions

  • the invention relates to a drain device for the removal of Water from a substantially flat surface, especially from a flat roof, through a wall section that delimits the surface, with one extending through the wall piece Pipe piece formed drain opening, a cover for closing the drain opening against air entry when reaching a Limit of the water level on the surface and with itself connecting the outside of the wall section to the pipe section Down pipe leading to full filling when the limit is reached of the water level and for the formation of a suction vacuum is dimensioned.
  • Flat roofs are regularly covered by a roof edge limited wall piece. It is known to go through flat roofs to drain drainage openings distributed on the surface, the Drainage openings routed regularly within the roof structure Bus lines are connected. Since the drain openings and the Collector lines require interventions in the roof structure, it is also known, such roof surfaces through the roof edge drain to drain through by a drain pipe through the wall piece of the roof edge is passed and a drain opening has in the surface of the wall piece, which for Surface of the flat roof is directed towards the surface of the flat roof, the water laterally through the wall section of the edge of the roof can run through.
  • the known drainage devices of this type have the disadvantage on that when the "start" of the suction effect despite the overshoot the limit of the water level due to vortex formation air is still sucked in, which on the one hand reduces the drainage capacity reduced, on the other hand causes considerable noise becomes.
  • the invention is therefore based on the problem of a drain device of the type mentioned at the beginning with regard to the performance and improve noise generation.
  • a drain device is used to solve this problem of the type mentioned at the outset characterized in that the Pipe section is continued on the surface outside the wall section and that the drain opening is spaced from the wall piece is arranged, an all-round inflow outside the pipe section towards the drain opening.
  • the drain opening through which the water through the wall piece that closes the surface, not in the wall piece itself, but at a distance from the wall piece arranged on the surface by placing the pipe piece on the surface continued outside the wall piece. That made it possible free flow to the drain opening from all sides - apart from from the pipe section forming the inlet opening - leads to a significantly improved drainage of water under suction, the undesired intake of air avoided or at least can be reduced.
  • the pipe piece in a pot arrangement forming the cover, the a circular cylindrical wall with itself over part of the Has height of the jacket wall extending inlet openings.
  • the height of the inlet openings suitably corresponds to that Limit of the water level, when reached the suction effect should "jump" so that through an increased drainage capacity again a reduction in the water level on the surface is achieved becomes.
  • the drain device according to the invention as an emergency drain, through which water is only drained off when the Surface has a minimum accumulation height.
  • This is the Pipe piece formed rising before entering the wall piece and enters the wall piece with a clear distance from the surface on. In addition, this will seal the pipe section relieved when entering the wall piece.
  • FIG. 1 shows a right-angled angle piece 1, which is connected with a horizontal leg to a roof surface (not shown) and with a vertical leg to a surface of a wall section (not shown) that forms the roof boundary (not shown).
  • a pipe section 2 is laid on the roof surface and on the horizontal leg of the angle piece 1, passes through a corresponding through opening of the vertical leg of the angle piece 1 and is passed through the width of the wall piece.
  • a curved angle piece 3 is connected to the pipe section 2, which produces a transition into a vertical downpipe 4.
  • the downpipe 4 has an upper drop section 5 which merges with a step-shaped narrowing 6 into a narrowing section 7, so that the falling section 5 has a larger diameter than the narrowing section 7.
  • the step-shaped narrowing 6 and the narrowing section 7 are expediently part of a correspondingly shaped funnel piece, that in the area of the constriction 6 and the constriction section 7 of a continuation of the diameter of the downpipe 4 Jacket tube piece 8 is surrounded.
  • a lid 9 Inspection opening 10 In the lower area of the downpipe there is a usual, lockable with a lid 9 Inspection opening 10.
  • the connections of the individual sections the downpipe 4 and the connection to the elbow 3 and Pipe section 2 is sealed with known socket connections 11 manufactured.
  • a free end of the pipe section 2 laid on the roof surface forms a vertical drain opening 12, which is somewhat located within a pot arrangement 13, since the pipe section 2 um led a small amount into the pot assembly 13 sealed is.
  • the pot arrangement 13 is upwards, above the pipe section 2, sealed airtight by a cover 14 and has a circular cylindrical jacket wall 15 in which there are inlet openings 16 are distributed over the circumference of the jacket wall 15.
  • the inlet openings 16 are vertical, open at the bottom Slits formed about halfway up the jacket wall 15 end, so that the inlet openings 16 from the Area starting only over part of the height of the jacket wall 15 extend.
  • the height of the inlet openings 16 corresponds to a limit of Water level on the surface.
  • Figure 2 illustrates that on both legs of the elbow 1, a sealing sheet 17, 18 is laid, which is pressed by an associated flange 19, 20 with the help of fastening screws 21 sealing against the relevant leg of the elbow 1.
  • FIG. 2 also shows that the pipe section 2 is divided in the area of the angle section 1 and is continued inclined downward by a small angle within the wall section (not shown).
  • FIG. 3 illustrates that the pot arrangement 13 is provided with a bottom designed as a mesh screen 22, which has the function of preventing the sealing membrane of the surface from being pulled up due to the negative pressure effect in the downpipe 4 - and thus in the pot arrangement 13.
  • the second embodiment of the invention shown in FIGS. 4 to 6 differs from the first embodiment shown in FIGS. 1 to 3 only in that the pipe section 2 ′ outside the wall section, that is to say in the area of the surface, with an obliquely upward section 23 is provided so that the pipe piece 2 'is passed through the vertical leg of the leg piece 1' at a distance from the surface or from the horizontal leg of the angle piece 1 ', whereby water drainage is only possible when the distance of the passage of the pipe piece 2 'of the area corresponding minimum accumulation height is present.
  • Such a drainage characteristic is used for emergency drains that only take effect when regular drainage devices are not sufficient due to blockages or excessive water to keep the surface water from rising below the minimum accumulation level.
