Definitions

  • the invention relates to vent roof tiles, in particular ridge connection vent tiles, which can be used for venting the ventilation cross section under the roof skin.
  • the ventilation cross-section on the ridge must be at least 0.5% of the associated roof area in order to protect the roof structure from moisture damage by adequate ventilation.
  • fan ridges are already known for roof ventilation. They can be attached to the ridge on gable roofs and also on hipped roofs. In the case of the fan ridge tiles known for this purpose, ventilation takes place through slots in the area of their mutual longitudinal overlap. The circulating air escapes from these openings.
  • the disadvantage of such fan ridge tiles is that flying snow can penetrate through the openings, so that moisture forms on the roof foil, the battens, etc.
  • the well-known ridge connection vent tiles have two edge contact surfaces for the ridge tiles in the header. Between the lower edge of the ridge tile resting transversely on the ridge connection ventilation tile and the surface of the ridge connection ventilation tile, there remains a transverse gap through which the circulating air supplied through the ridge tile exits.
  • a vent roof tile according to the preamble of claim 1 is known from DE-C-466 548.
  • the invention is therefore based on the object to improve the known ridge connection breather tiles to the effect that they no longer have the disadvantages of the known ridge connection breather tiles mentioned above, ensure reliable ventilation of the roof surface and at the same time provide the greatest possible protection against the ingress of water and snow deliver. Furthermore, it is an object of the invention to further develop ventilation bricks with ventilation dormer and fan ridge bricks in such a way that the roof surface is vented properly and safely and the ingress of water, in particular by driving rain and snow, in particular flying snow, is prevented.
  • the channels serve as ventilation openings for the discharge of the circulating air flowing out through the ridge tiles, the cams and / or webs at the same time as protection against the ingress of moisture.
  • This protection is achieved in particular if, according to a preferred embodiment of the invention, the individual webs are formed from web sections that are angled to one another and connected to one another. The resulting labyrinthine course of the channels deflects the air flow, but does not prevent it from escaping, while providing protection, in particular, against the penetration of flying snow and the like. Further advantageous cam or web designs result from the subclaims and the drawing.
  • the head area of the brick is shielded by a damming bar which is separated from the webs by a transverse channel and runs across the brick surface.
  • the ventilation ducts are shielded from the particularly high dynamic pressure at the base of a ridge of the air flow passing over the roof surface.
  • the inventive design of the head field of the ridge connection vent brick can only fully develop its effect if, when installing the ridge connection vent brick, the ventilation cross section remains freely accessible to a sufficient extent, that is, it is not constricted too far from the ridge tiles placed on it.
  • limiting cams are preferably provided in the header of the ridge connection vent tile for safety reasons, which form stops for the position of the ridge tiles on the ridge connection vent tile.
  • the design of the vent brick with ventilation dormer according to the invention is carried out in such a way that the front opening of the ventilation dome is juxtaposed with a baffle bar, the height and shape of which, for. B. corresponds to the ventilation gap, but can optionally also be designed with a greater height.
  • the end faces of the venting bead and the baffle bar face each other at a short distance, while the outer surfaces of the breather bead and the baffle bar are in their common shape, for. B. to a fluidically favorable form (streamlined form).
  • the arrangement of the baffle bar prevents the wind that is present at the ventilation gap from generating a dynamic pressure.
  • the latter is also provided with a damming bar at one end or at both ends, which has the task of guiding the air flowing past and creating a suction at the ventilation gap between two adjacent tiles, which prevents the ingress of rain or snow effectively prevented.
  • a ridge connection vent tile 1 is designed as a folded tile and has an approximately semicircular bead 3 which laterally adjoins the tile surface. On the longitudinal side of the tile 1 opposite the bead 3, folded grooves 4, 5 and 6 are provided.
  • the so-called head field 7 of the brick 1 is delimited by a head edge strip 8, which is drawn up along the head-side outer edge of the brick 1 and by a storage ledge 9 running parallel to the head edge strip 8 at a distance from the latter across the brick surface 2.
  • the stowage bar 9 also delimits the head-side end of the bead 3.
  • a web labyrinth 10 (see FIG. 4a) is provided in the head field 7, specifically in the area between the head edge strip 8 and the storage rail 9.
  • This labyrinth 10 is formed from a multiplicity of webs 11 which run adjacent to one another and ventilation channels 12 for the discharge of the ridge tile from the roof ridge vent tile 1, not shown here, which is fed transversely, ascending from the roof interior and through the openings of the ridge tile limit escaping circulating air.
  • the webs 11 are formed according to the schematic representation in Fig. 4a from mutually angled, interconnected web sections 11 a, 11 b.
  • Such a configuration has the advantage that the circulating air can escape from the ventilation ducts 12, but flying snow or blow water cannot penetrate through the ridge tile and get under the roof skin.
  • the arrangement of the webs chosen here has the particular advantage that, despite the shielding achieved, it does not unnecessarily reduce the usable vent cross section.
  • FIG. 4a The blocking effect of the web arrangement shown in FIG. 4a becomes particularly clear from the arrangement of the webs 11 shown in perspective view in FIG. 3, the cross-sectional profile of which has the shape of a trapezoid.
  • the webs 11 are arranged side by side so that their apices 11c are approximately at the level of the leg ends of the adjacent web 11. This achieves the desired redirection of the air and at the same time impedes the penetration of moisture.
  • a similar effect can also be achieved by web or cam arrangements, as are indicated schematically in FIGS. 4b, c and d. 4b it is webs 20 with also an angular connection in the form of an “S •, in FIG. 4c a meandering configuration 21.
  • the cam arrangement shown in FIG. 4d is formed from parallel, parallel rows of cams 22, 23, 24.
  • the cams are arranged at a distance from one another within a row of cams.
  • the cams of adjacent rows 22, 23, 24 each sit on a gap.
  • Such a cam arrangement offers particularly good protection against the ingress of water or snow.
  • it must be accepted that the ventilation cross section available for the circulating air is considerably reduced compared to the web arrangement shown in FIG. 4a.
  • the baffle bar 9 is arranged at a distance from the base point of the webs 11. Its cross-sectional profile, which can be seen in FIG. 2, is selected such that it causes a flow profile indicated by the flow lines in FIG. 2 for the air flowing over the roof towards the ridge. At the points of high streamline density, a negative pressure forms which exerts a suction on the circulating air flowing through the channel 13 in the direction of the arrow P and thus favors the discharge of the circulating air.
  • the profile of the brick surface 2 facing side of the storage rail 9 has z. B. an approximately hyperbolic shape, the hyperbola approaching the brick surface 2 or the storage surface 9 asymptotically.
  • the height of the storage bar 9 is greater than that of the top edge bar 8.
  • Another function of the raised baffle bar 9 is to prevent the ingress of moisture into the channels 12 connected to the ridge tile.
  • This moisture protection is, as already explained, reinforced by the shape of the webs 11, which block access to the ventilation slots of the ridge tiles in a labyrinth-like manner and thus make the penetration of flying snow and moisture almost impossible.
  • limiting cams 14 and 15 are provided on the top edge strip.
  • the limiting cam 14 is arranged in the area of an edge support bar 16 provided laterally on the brick 1 and extends transversely to the storage bar 9 in the direction of the head bar 8.
  • the limiting cam 15 is also in the form of a hump 15 in the area of the edge support bar 16 on the top edge bar 8.
  • the 6, 7 is open on the end face 27 and has a storage bar 28, the end face 29 of which faces the end face 27.
  • the distance between the two end faces 27 and 29 is, for example, 20 mm and can be between approximately 10 and approximately 50 mm.
  • the storage rail 28 is curved on the side facing away from the end face 29, z. B. formed in cross-section part-circular, such that the outer surface 30 of the baffle 28 and the outer surface of the ventilation bead 26 complement each other to form a streamlined shape.
  • the baffle bar 28 can also project significantly beyond the ventilation bead 26.
  • baffle bar 32 is either provided at the overlapped end of the ridge tile, or baffle bars 32, 33 are provided at both ends of the ridge tile, the opposing baffle bars 32, 33 in each case 'two adjacent ridge tiles z. B. add so that a streamlined transition is achieved on the two facing ram ledges, which causes suction in the air duct 34.
  • one baffle bar can be made significantly higher than the other.
  • the curved surface of the baffle strip (s) can generally be concave or convex.
