Definitions
- the present invention relates to devices for evacuating rainwater from the surface of a building roof and relates more particularly to disposi ⁇ tive evacuation devices with closed or siphoid flow.
- Such a flow is characterized in that the pipe in which the water flows is full, without air entrainment.
- a conduit for collecting and evacuating rainwater on the surface of the roof of a building comprising a discharge pipe the upper end of which is assembled with a collecting trough of section larger than that from the pipe inlet.
- the upper edge of the tank is placed higher than said orifice.
- a full cover, the section of which is intermediate between the section of the orifice and that of the tank, is fixed above the orifice and assembled with a strainer whose wall surrounds the inlet opening of the pipe.
- the strainer is pierced with holes the surface of which is such that the ratio between the total passage area of the perforated wall of the strainer and the section of the discharge pipe is between 2.5 and 3.5.
- the invention aims to remedy the aforementioned drawbacks of known devices by creating a discharge device which, while being of simple construction, allows: - to obtain the lowest possible height of water on a roof fitted with it and in any case less than 55 mm for normal flow,
- a device for evacuating rainwater from the surface of a building roof comprising a vertical evacuation pipe surmounted by a tank with a section larger than that of the pipe and intended to be flush with the surface of the roof and an anti-vortex device of intermediate section between that of the pipe and that of the tank, disposed in said tank, above the inlet end of the discharge pipe, characterized in that the anti-vortex device comprises a solid wall of conical shape provided with axial peripheral fins in contact with the bottom of the tank surrounding the inlet of the drain pipe and defining with said bottom radial passages for water to said drain pipe, and in this that its conical wall is arranged opposite a frustoconical portion of the wall of the tank to form with the latter a passage for water, the ratio between the section of the passage for water defined between the conical wall of the device anti-vortex and the frustoconical wall portion of the tank on the one hand and that of the evacuation pipe on the other hand, being close to 1.
- Fig.l is a view in elevation and in cross section of the rainwater evacuation device according to the invention in place in a roof slab;
- - Fig.2 is an exploded view of the anti-vortex device and the cover or strike guard with their assembly rod removed from the tray.
- a rainwater evacuation device placed in a roofing slab D. It mainly comprises a vertical pipe 1 for evacuating water also called stump surmounted by 'a tub or pot 2 of generally cylindrical shape with a section greater than the section of the pipe 1 and connected to the latter by a wall portion 3 of frustoconical shape.
- the pot 2 has at its end flush with the slab D, a plate 4 of generally square shape placed on the slab D and thus ensuring the tightness of the connection between the slab and the evacuation device.
- an anti-vortex device 5 comprising 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 wall portion 3 of frustoconical shape and forms therewith a passage 6a for water to the discharge pipe 1.
- axial fins 7 regularly distributed.
- the evacuation device is provided with a hat or strike guard 8 surrounded by an anti-glitter system 9 placed on the plate 4 and intended to retain the majority of debris or flakes which come off from certain roof coverings. and that risk blocking the horizontal pipes of a rainwater drainage system.
- the fins 7 are connected to the conical wall 6 in an intermediate zone of their length and are advantageously diametrically opposite in pairs and directed along their width towards the center of the conical wall 6
- the ends of the fins 7 located on the side of the hollow of the conical wall 6 and therefore turned towards the end of the bowl 2 carrying the plate 4 are connected together by a strapping ring 10, while the ends of the fins 7 opposite to said ring terminate in points 11 by which the anti-vortex device 5 rests on the bottom 12 of the bowl 2 which surrounds the orifice of the discharge pipe 1.
- the anti-vortex device 5 comprises, above the frustoconical wall 6, an annular grid 14 formed by the conical wall 6,1'ringing ring 10 and the portions of the fins 7 joining them and below the wall frustoconical a portcullis 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 of the 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 points 11 of the fins 7 also prevents the formation of vortices in the water streams which enter the pipe 1.
- the anti-vortex device 5 comprises centering studs 16 arranged at 120 ° with respect to each other and each projecting with respect to an axial fin 7.
- the studs 16 are part of a circle of diameter equal to that of the pot or tray 2 and thus ensure the centering of the anti-vortex device in the pot.
- the presence of the fins 7 causes a radial flow of water from the periphery towards the center of the bowl 2 and consequently prevents any formation of swirls liable to entrain air towards the evacuation pipe or stump. 1.
- the cap or strike guard 8 of the device has a domed shape and has slots approximately radia ⁇ les. It has a diameter adapted to that of the bowl 2 and has axial fins 22 bearing on the rim of the bowl 2 regularly distributed around its periphery, one in two for 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 centering fingers can be chosen different.
- the fins 22 define, with the plate 2 of the bowl, passages 25 for access to the rainwater in the bowl 2.
- the frustoconical wall 6 of the anti-vortex device 5 and the cap or strike guard 8 each comprise a central orifice in which is engaged a sliding fastening rod 26 comprising a head 27 and carrying at its end opposite to the head, a washer of blocking 28 after crushing of the corresponding end of the rod 26.
- This rod allows a slight axial movement of the strike guard 8 relative to the anti-vortex device 5 and promotes:
- the ratio between the section SI of the passage 6a defined between the conical wall 6 of the anti-vortex device 5 and the frustoconical wall 3 for connecting the evacuation pipe 1 with the bowl 2 on the one hand, and the section S2 of said pipe (Fig.1) on the other hand, is according to the invention chosen close to 1.
- the anti-glitter system 9 is in fact a filtering system.
- It consists of a ring 30 of perforated sheet metal provided with a rim 31 for stopping debris. It can also be formed of a ring made of a metallic or textile mesh or also of foam.
- the mesh For light rain generating a roof water height lower than the filter height, the mesh retains the glitter but not the water.
- the purpose of the upper plane or rim 31 of the filter is to contain the flakes which can float when the water begins to rotate around the birth.
- the anti-glitter filter 9 therefore has a height which corresponds to the height of water for which the birth (therefore the channeling system) begins to operate as a siphoid and therefore can no longer be blocked by the glitter (hydrocuring).
