Definitions

  • the invention relates to a ridge ventilation device, consisting of an outside, curved outward, provided with an opening in the apex area of the ridge cover element and an insert arranged in the cavity of the ridge cover element for collecting and discharging penetrating precipitation, as described in the preamble of independent claim 1.
  • First venting devices of this type serve to discharge air moisture penetrating into the roof space to the outside. They are also intended to prevent the build-up of heat and cold and to balance the pressure between the inside and outside in strong winds.
  • a ridge ventilation device in which the insert consists of two upwardly curved and superimposed shell elements, each of which is provided with air passage openings.
  • the air passage openings are offset from one another as seen over the bulge periphery.
  • a generic ridge ventilation device is described in DE-A-33 01 273.
  • this document discloses an insert which is arranged essentially at a gap and at a predetermined distance from the opening of the ridge cover element. It has two shoulder-like side parts arranged on both long sides below the middle part and at a horizontal distance from one another.
  • a ridge ventilation element in which a central part covers the space between two side parts to form a lateral protrusion. There are lateral openings between the side edges of the central part and the associated side parts.
  • the invention has for its object to provide a generic ridge ventilation device in which the air throughput is improved.
  • the invention has the advantage that the deflection of the air flow is reduced to a minimum and that the cross-sectional areas of the air path can be kept relatively large in relation to the dimensions of the ventilation device. A correspondingly larger roof area can therefore also be ventilated for each ventilation device.
  • the shape of the insert is simple and clear, the laying of the ventilation device is simplified, so that the labor costs for roofing can be kept low.
  • the tear-off edge has the effect that a draft flowing along the roof creates a negative pressure above the opening, so that the roof ventilation is supported by the suction effect.
  • the swirling of an air stream sweeping along the roof and the generation of a vacuum area is further increased by the fact that a further tear-off edge is arranged parallel to the tear-off edges running in the longitudinal direction and below them on the surface of the outer element.
  • This further tear-off edge also has the advantage that a defined, reinforced rib is present, which serves as a support during stacking of such elements during transport and storage. The weight of the stacked elements is therefore controlled downwards through these reinforced areas, so that the risk of breakage is reduced.
  • ribs projecting inward into the cavity corresponding to the further rib-like tear-off edges.
  • they also perform other functions relevant for ventilation. They protect the ventilation duct against external air that could penetrate between the longitudinal edges of the outer element and the associated roof panels in the contact area of the outer element.
  • they fix the inner element preferably with the aid of an elastic base element that generates a predetermined preload and prevents rattling noises. Adequate water outlet is achieved through recesses in these ribs on the underside.
  • a foam material as is known as a Komprie sealing tape, has proven to be particularly suitable for the elastic underlay. This material adapts to the profile and the surface of the associated roof tiles without having to be shaped accordingly in a separate machining process. It can also be easily glued to the underside of the insert.
  • Reliable drainage of precipitation is achieved in that the middle part is provided with a drip edge.
  • the inner edges of the side parts are provided with an upward-facing collar, which keeps the under-roof reliably dry even in the case of large amounts of water, for example in the event of a downpour.
  • the drip edges and the collar also serve to stiffen the insert lengthways.
  • the passage cross section between the middle part and the side parts is at least impaired in that the spacer consists of at least two transverse ribs.
  • the ribs also connect the two side parts to one another, so that overall a relatively rigid body is formed.
  • vertical transverse ribs are present on the upper side of the central part, which extend into the area of the opening of the cover element.
  • the ribs also have the advantage that they form a grid that prevents the ingress of leaves, small animals or the like. prevent. They also prevent precipitation from sloping.
  • a spoiler element consisting of a horizontally running spoiler cap and vertical spoiler carriers placed on the insert.
  • the spoiler cap When assembled the spoiler cap is located above the opening of the cover element. It creates a venturi effect, through which air is extracted from the sub-roof.
  • 10 is a fired clay clay roof element (ridge ventilation tile). It is provided in the apex region with a slot-shaped opening 11 which runs in the longitudinal direction and is provided on all edges with a tear-off edge 12 which projects upwards.
  • the example shown in FIG. 1 also has two further tear-off edges 13, 13 ', which run parallel to the longitudinal direction of the ridge cover element 10 or the opening 11 at a predetermined distance from the tear-off edge 12 on both outer sides of the ridge cover element 10.
  • the ridge cover element is provided with two support ribs 14, 15 which run in the longitudinal direction and project substantially freely vertically into the cavity. They are essentially below the further tear-off edges 13, 13 ′, so that when several such ridge cover elements 10 are stacked, the support ribs 14, 15 come into engagement with and are supported on the further tear-off edges of the ridge cover element located below each. Within a stack, the weight of the ridge deck elements is therefore taken up in the area in question by the further tear-off edges 13, 13 'and supporting ribs 14, 15 and is derived downward.
  • first layer insert In the cavity of the first cover element 10 there is an insert 20 made of plastic (first layer insert), which is an air-permeable and precipitation-resistant chicane.
  • the length of the insert 20 can match the length of the ridge cover element 10. However, it is preferably an integer multiple of the length of the ridge cover element 10.
  • the insert 20 consists of two longitudinally parallel side parts 21, 22 arranged at a distance from one another and a middle part 23 bridging the space between the side parts 21, 22 at a predetermined distance
  • the middle part 23 and the two side parts 21, 22 are essentially connected to one another at the end faces by means of spacers 24 which form transverse ribs. For longer missions 20 there are several such spacers 24 'distributed over the length.
  • a plurality of inserts 20 can be pushed into one another at the end side in such a way that one end side of each insert 20 is open (not shown), ie that the end spacer 24 in question is removed.
  • 1 further illustrates two guide surfaces 42, 43, recesses 18 in the supporting ribs and partially a rib insert 46.
  • roof tiles 32, 33 are placed on the two uppermost roof battens 30, 31 oriented perpendicular to the plane of the drawing. Between the upper ends of the roof tiles 32, 33 there is a passage gap 34 for venting the roof space 35. Along the edges of the roof tiles 32, 33 and adjoining roof tiles (not shown) there is in each case a strip-shaped, elastic foam pad 36, 37, which as Komprie sealing tape is known.
  • the insert 20 with its side parts 21, 22 rests on these two documents 36, 37. Since the documents 36, 37 adapt to the outer contour of the roof tiles 32, 33, a form-fitting, essentially airtight seal between the roof tiles 32, 33 and the insert 20 is achieved.
  • the supporting ribs 14, 15 of the ridge cover element 10 press onto the areas of the side parts 21, 22 supported by the documents 36, 37.
  • the insert 20 is glued to the documents 36, 37.
  • the ridge cover element 10 is not supported on the documents 36, 37, but lies with its lower edge 17 on the roof tiles 32, 33. It can be fixed to the central part 23 by means of the transverse ribs 44 which extend over the edge of the opening 11.
  • the rib insert 46 in the example shown is releasably attached to the insert 20.
  • the supports 52 (FIG. 3), like the ribs 44, can form a protective grid against leaves, birds, etc.
  • the supports 52 and the ribs 44 also fix the ridge deck element 10 'in its position.
  • the transverse ribs 44 are connected to one another above the latching lug with a longitudinal rib 45, the height of which is such that it does not obstruct the air flow.
  • the middle part 23 of the insert 20 is arranged exactly below the opening 11 of the ridge cover element 10 and at a predetermined distance from the inside of the ridge cover element 10. It is provided with a slight outer curvature and with a protrusion over the two side parts 21, 22 so that penetrating precipitation flows onto the side parts 21, 22. As a precaution, drip edges 27 are formed along the edges of the middle part 23.
  • the underlying edges of the two side parts 21, 22 are provided with a collar 28 which prevents rainwater from flowing into the space 38 between the two side parts 21, 22.
  • the side parts 21, 22 are provided with a slight external inclination. The drainage takes place essentially through recesses 18 open at the bottom in the contact area of the support ribs 14, 15.
  • the middle part 23 is arranged essentially at a gap to the opening 11.
  • the two side parts 21, 22 end on their outer sides in drip edges 29 bent downward, which laterally overlap the documents 36, 37.
  • Air from the roof space 35 passes through the passage gaps 34 and the overlying space 38 to the middle part 23, where it is deflected laterally and flows through the openings 25, 26 according to arrows 39 into the passage 40, 41 between the middle part 23 and the ridge cover element 10. From there it can escape freely through the opening 11 to the outside.
  • the tear-off edge 12 tears off the flow of the air currents flowing along the roof from the outside. This creates a vacuum suction effect, which the Roof ventilation supported.
  • side guide surfaces 42, 43 which extend downward on the insert 20 and extend from the inner edges of the side parts 21, 22 to the area of the roof battens 30, 31 (show in dashed lines). They can also be used to nail or screw the insert 20 onto the roof battens 30, 31.
  • a plastic spoiler cap 50 is placed on the middle part 23 'of the insert 20'. It consists of a downwardly curved spoiler 51 above the opening 11 of the ridge deck element 10 ', which narrows the passage cross-section in order to accelerate a cross flow 53. A venturi effect is created, which draws air from the roof space according to arrow 54.
  • the spoiler 51 is detachably attached to the insert 20 in the example shown via supports 52 which are aligned in the direction of the transverse flow 53, as was described in connection with the transverse ribs 44 in FIG. 2.
