Definitions

  • the invention relates to a rainwater collector, in particular for a flat roof, with a water inlet opening arranged at the top, a lower diameter smaller water outlet opening and an intermediate, rotationally symmetrical relative to a vertical axis intermediate portion whose inner wall projecting along a flat top inclined to a horizontal plane and down at a distance from the horizontal plane, steeply extending into a extending around the vertical axis extending inner cylindrical surface extending, extending in a vertical plane spanned by the vertical axis extending contour line.
  • Rainwater collectors are used on flat roofs. They have an upper region extending in a horizontal plane, to which a rotationally symmetrical intermediate region adjoins, which merges into a cylinder section spaced apart from the horizontal plane. Such a rainwater collector is from the WO 99/51834 previously known.
  • the intermediate portion has a rounded contour line and ribs intended to cause the water flowing into the water inlet opening into circular motion.
  • the flow channel has a plurality of curvature sections.
  • a first, to the Horizontal plane adjacent curvature section is formed by a retracted into the discharge funnel roof sheet.
  • the curvature course of the first curvature section is predetermined by a base body.
  • An adjoining second curvature section is formed by a clamping ring.
  • Rainwater collectors for flat roofs are also known from EP 0502493 B1 and the WO2010 / 103371 A1 , The latter also has a leaf trap grille.
  • the invention has for its object to optimize a rainwater collector of the generic type hydromechanically.
  • the contour line is designed in such a way that there is no backflow or stall in the runoff.
  • the contour line is designed so that the vertical component of the velocity of water pressurized from above by pressure of an upper water column and down by suction of a lower water column in each volume region of the intermediate region is greater than the radial component of the water velocity.
  • the relevant function R D 0 * H / x 1 ⁇ 4 * C + K describes for each distance x from the horizontal plane in the region between the horizontal plane and cylinder surface a radial distance of the contour line to the vertical axis, where it can be seen that the radial distance is proportional to the fourth root of the reciprocal distance x.
  • the proportionality constant C and a linear constant K are essentially freely selectable, but are preferably in a range between 0.1 and 2 in each case.
  • D 0 also corresponds here to the diameter of the cylindrical section.
  • a second aspect of the invention relates to a preferred constructive embodiment of a hydromechanically optimized flat roof outlet, wherein it is essential that the above-mentioned contour line has three consecutively adjoining one another in the radial direction curvature sections which can be different degrees inclined relative to the vertical axis, but also different degrees curved.
  • the rainwater collector has a base body which has a horizontal section which lies in the horizontal plane and which is covered by a roofing membrane, for example a roof underlay membrane or a sealing foil. At the extending in the horizontal plane horizontal section is followed along a circular line an annular first curvature section, whose Surface is formed by the resting on the body sealing membrane or roof underlay.
  • a radially adjoining second curvature section which is inclined more strongly with respect to the vertical axis, is formed by a clamping ring which clamps an opening edge region of the sealing web between itself and the base body.
  • the clamping ring overhangs the edge of the opening and continues into a cylindrical portion which is in a neck of the body.
  • the cylinder portion of the clamping ring preferably has an external thread which is screwed into an internal thread of the neck.
  • the third curvature portion which adjoins the second curvature portion and is inclined more toward the vertical axis than the second curvature portion, is formed by a support ring of a leaf trap body.
  • the third curvature portion merges into a cylinder inner circumferential surface formed by a cylinder portion of the leaf catcher body.
  • the radially outer peripheral edge of the clamping ring extends at an acute angle and lies in the installed state in a plane which is parallel to the horizontal plane, so that it forms only an insignificant kink between the first curved portion and the second curved portion.
  • the radially inner edge of the second curvature section is substantially flush with the radially outer edge of the third curvature section.
  • the leaf catcher preferably has leaf catcher webs extending upwardly from the support ring of the leaf catcher body.
  • the leaf catcher webs extend obliquely upward in the direction of the axis of the cylinder sections and open into a cover section in which the leaf catcher webs are connected to one another.
  • the leaf catcher webs have an elongated cross section. They are thus formed as a flat body, wherein the longitudinal axes of the cross-sectional surfaces extend in the radial direction.
  • the wall thickness of the leaf catcher webs is less than the distance between two leaf catcher webs in the circumferential direction.
  • the clamping ring preferably has guide ribs in the second curved section.
  • the guide ribs extend in the radial direction from the radially inner peripheral edge of the second Curved portion, in which the second curved portion merges into the inflow surface, until immediately adjacent to the radially inner peripheral edge of the second curved portion.
  • the guide ribs which are aligned with the leaf catcher webs in the radial direction force the water flowing into the rain collector into a radial flow.
  • the acceleration forces are adjusted as a result of the contour of the contour line such that the vertical component of the velocity of the water acted upon from above by pressure of an upper water column and down by suction of a lower water column in each volume region of the intermediate region is greater than the radial component of the water velocity. This dimensioning avoids vortex formation and Aufstau bine.
  • the leaf catcher body is connected to a locking tongue with the clamping ring.
  • a latching tongue connects to the support ring, which has a latching projection which engages in a latching niche of the clamping ring.
  • Below the clamping ring an outlet pipe is screwed into the internal thread of the neck of the body with an external thread.
  • the connecting pipe may have a Reduzierabêt in which reduces the inner diameter of the connecting pipe.
  • the upper section of the connecting pipe may, for example, have a diameter of 160 mm, so that the pipe diameter in the reducing section can be reduced to the standard diameters 150 mm, 125 mm, 100 mm, 70 mm, 50 mm.

  • the horizontal portion 2 is adjoined along a circular boundary line by a first curvature portion 4, which is the beginning of a funnel-shaped depression which opens into a connection pipe 35.
  • the first curvature section 4 is followed in planar contact with the roof underlayment membrane or sealing foil, which is clamped with its section 33 adjoining a circular opening edge 34 between a sealing ring 6 inserted in an annular groove 5 of the base body 1 and a clamping ring 12.
  • the opening edge 34 of the roofing membrane 30 or sealing foil is located in a free space 7 between the main body 1 and the clamping ring 12.
  • Axially with respect to a passing through the center of the rainwater collector vertical axis A extends below a curved portion of the base body 1, a cylindrical portion of the base body 1, which forms a neck 8.
  • the outer wall of the neck 8 has ribs 11 in the form of an external thread.
  • the inner wall of the neck 8 has an internal thread 9.
  • a radially outer peripheral edge of a second curved portion 13, which is formed by a peripheral portion of the clamping ring 12 is obliquely cut so that it extends in a horizontal plane and forms an inflow surface 15.
