Definitions

  • the present invention relates to devices for evacuating rainwater from the surface of a roof building and relates more particularly to closed or siphon discharge devices.
  • Such a flow is characterized by the fact that the line in which the water flows is full, without air entrainment.
  • a full cover, the section of which is intermediate between the section of the orifice and that of the tray is fixed above the hole and assembled with a strainer whose wall surrounds the inlet opening of the pipe.
  • the strainer is pierced with holes whose surface is such that the ratio between the total area of passage of the perforated screen of the strainer and the pipe section evacuation is between 2.5 and 3.5.
  • a rainwater evacuation device which includes a vertical evacuation pipe surmounted by a section larger than that of the pipe and intended to be flush the roof surface, an anti-vortex device, intermediate section between that of the pipe and that of the tray, disposed in said tray above the end outlet pipe inlet.
  • This anti-vortex device has a wall full deflector with three fins devices in contact with the bottom of the tank and extending into the drain pipe by defining three radial passages for water.
  • This solid wall is arranged opposite a curved portion of the wall of the tray to form, with the latter, passages for the water.
  • an evacuation device stormwater from the surface of a building roof comprising a vertical discharge pipe surmounted by a tank with a cross-section larger than that of the pipe and intended for flush with the roof surface and an anti-vortex device of intermediate section between that of the pipe and that of the tank, placed in said tank, above the inlet end of the drain hose, the device anti-vortex with a solid wall provided with fins axial peripherals, external to said solid wall, in contact with the bottom of the tank surrounding the inlet of the pipe evacuation and defining with said bottom passages radials for the water towards said drainage pipe, characterized in that the solid wall of the anti-vortex device is conical in shape and in that it is arranged next to a frustoconical bottom portion of the tank for form with it a passage for water, the relationship between the section of the passage for defined water between the conical wall of the anti-vortex device and the frustoconical portion of the tank on the one hand and that of the on the other hand, being close to 1.
  • FIG 1 there is shown a device rainwater evacuation according to the invention set place in a roof slab D.
  • the pot 2 has at its end flush with the slab D, a plate 4 of generally square shape placed on slab D and thus ensuring the tightness of the connection between the slab and the evacuation device.
  • an anti-vortex device 5 having a solid conical wall 6 of conicity directed towards the end of the pipe 1 connected to the pot 2.
  • the conical wall 6 is arranged opposite the portion of bottom 3 of frustoconical shape and forms therewith a passage 6a for water to the drain pipe 1.
  • axial fins 7 regularly distributed.
  • the evacuation device is fitted with a hat or strike guard 8 surrounded by a straw system 9 placed on the plate 4 and intended to retain the majority of debris or flakes that peel off from certain coatings roof and who risk blocking the horizontal pipes of a rainwater drainage system.
  • the fins 7 are connected to the conical wall 6 in an area intermediate in their length and are advantageously diametrically opposite two by two and directed according to their width towards the center of the conical wall 6.
  • the ends fins 7 located on the hollow side of the wall conical 6 and thereby turned towards the end of the bowl 2 carrying the plate 4 are interconnected by a strapping ring 10, while the ends of the fins 7 opposite to said ring end with tips 11 by which the anti-vortex device 5 rests on the bottom 12 of the bowl 2 which surrounds the orifice of the drain hose 1.
  • the anti-vortex device 5 comprises above of the frustoconical wall 6, an annular grid 14 formed by the conical wall 6, the strapping ring 10 and the portions of the fins 7 joining them together and below from the frustoconical wall a harrow for the passage of water between the portions of the fins 7 located below the frustoconical wall 6 and which are in contact with the bottom 12 from bowl 2.
  • the upper grid 14 prevents the formation of vortices in the bowl formed by the conical wall 6, while the harrow formed by the ends provided with tips 11 of fins 7 also prevents formation eddies in the streams of water entering hose 1.
  • the device anti-vortex 5 has centering pads 16 arranged at 120 ° to each other and making each projecting from an axial fin 7.
  • the studs 16 are inscribed in a circle of diameter equal to that of the pot or tank 2 and thus ensure the centering of the anti-vortex device in the pot.
  • the presence of the fins 7 causes a flow radial water from the periphery to the center of the bowl 2 and consequently prevents any formation of vortices likely to cause air to the pipe evacuation or stump 1.
  • the cap or strike guard 8 of the device has a domed shape and has roughly radial slots 20. It has a diameter adapted to that of bowl 2 and has axial fins 22 bearing on the rim of the bowl 2 regularly distributed around its periphery, one in two per example of these fins comprising a centering finger 24 intended to come into contact with the inner wall of the bowl or tray 2.
  • the number of axial fins 22 provided with fingers of centering can be chosen different.
  • the fins 22 define with the plate 2 of the bowl of the rainwater access passages 25 in the bowl 2.
  • the frustoconical wall 6 of the anti-vortex device 5 and the hat or strike guard 8 each have a central hole in which is engaged a rod of sliding fastening 26 comprising a head 27 and bearing at its end opposite to the head, a washer of blocking 28 after crushing of the corresponding end rod 26.
  • the anti-glitter system 9 is in fact a system filtering.
  • It consists of a sheet metal ring 30 perforated with a rim 31 for stopping debris. he can also be formed of a ring in a metallic mesh or textile or even foam.
  • the mesh For light rain generating a height of water on a roof lower than the height of the filter, the mesh retains glitter but not water.
  • the purpose of the upper plane or rim 31 of the filter is contain the glitter that can float when water begins to revolve around birth.
  • the glitter filter 9 therefore has a height which corresponds to the water height for which birth (so the channeling system) begins to operate as a siphoid and therefore cannot no longer be blocked by glitter (hydro-cleaning).
