Definitions

  • the invention relates to a longitudinally folded roofing panel according to the preamble of claim 1.
  • FIG. 1 Another well-known roof covering plate (see EISENBERGER double interlocking tile, model E 20) points to the Front of her foot on a sieve-like formation, in which the air passage area consists of the sieve openings.
  • This roof covering plate for ventilation has the disadvantage that at about vertical and also at diagonal flow to the roof ridge at the sieve-like openings creates a dynamic pressure, which aeration of the underlying roof space either hindered or even thwarted.
  • These sieve-like types achieve the best ventilation effect Inserts with a negative pressure, such as on the leeward side due to a flow separation in arises near the ridge.
  • a concrete roof tile for ventilation is known from a prospectus sheet "concrete roof tiles" by the applicant, which is provided with a hood ventilation made of plastic inserted into an opening in its central fold.
  • This concrete roof vent is largely independent of the air flow direction, but with the Disadvantages of a multi-part, complicated shape and an unpleasant visual conspicuous, because the Plastic insert protrudes over the surface of the roofing panels and an inhomogeneous visual impression leaves.
  • a fan tile from the "Fan tile” brochure from the company Laufen which is a cant has at its foot end and is provided with an opening over almost the entire width of its foot, in which a sieve-shaped insert is inserted.
  • This sieve-like insert protrudes with its underside for holding penetrating precipitation relatively far below the bottom towards the head side, which in turn the Flow path and the air to be discharged from the roof space extended and higher pressure losses.
  • rainwater can nevertheless occur if the back pressure is present on the windward side penetration.
  • this fan tile has an impact surface that is favorable for a detachment process, it is also included suffers from the disadvantage of a lower part made of polypropylene plastic or metal.
  • the object of the invention is a longitudinally folded roof covering plate of the type mentioned to create ventilation, on the one hand visually inconspicuous with the same ventilation roofing panels, but also with conventional roofing panels of the same type Form is relocatable, largely independent of the wind direction due to relatively large flow cross-sections always ensures effective ventilation and yet the penetration of precipitation into the attic safely prevented.
  • this design now for the first time creates a ventilation passage area between the top of the water fold side of one and the bottom of the cover salt side of the other neighboring Roof covering plate created, which is visually perceptible only with special attention.
  • Ventilation technology this arrangement is linked to the incomparable advantage that regardless of the direction of flow Outside air always has a venting effect due to signs of detachment of the outside air in the vicinity of the longitudinal fold or the foot end that acts as a baffle edge is ensured. The greatest venting effect is with an inflow of the roof parallel to the ridge longitudinal axis.
  • this longitudinally folded roofing sheet is that the appearance of its surface of a conventional longitudinally folded roofing sheet of the same kind by a layperson not or hardly is distinguishable and a multi-part embodiment is unnecessary, since the projections causing the air passage slots are cohesively connected to the relevant roof covering plate for ventilation and in one Operation in the pressing of such roofing sheets are made.
  • penetrating precipitation is hermetically prevented from entering the roof space and below fully exploited the specific function of the water rebate side towards the eaves.
  • the roof covering plate according to the invention with convective ventilation due to differences in density the air in the roof space has a better ventilation effect due to the relatively large air passage slots than the conventional roofing tiles described in the prior art.
  • the roof covering plate according to the invention can be designed as a ridge connecting tile, that her head with a flat support surface for the ridge tile and with a parallel to the longitudinal axis of the ridge Baffle edge is provided to prevent precipitation.

There is a possibility of moving and good adaptability of such a roof covering plate for ventilation with the adjacent roof covering plate same type, with the protrusions on the bearing base protruding beyond the level of the water rebate surface Place on a roof covering plate for ventilation.
  • the projections can be inside a corresponding tolerance range.
  • the air passage areas are in the form of air passage slots, which are each several centimeters long and therefore also in connection with the height of the projections for a cheap one Ensure air passage.
  • the areas of the bearing base and stop edges are approximately are of the same width and run at an angle of inclination between 0 ° and 30 ° to the horizontal in the direction on the foot of the roofing slabs.
  • the purpose of this tendency is to have falling precipitation below it To allow gravity to flow towards the eaves. Since the protrusions on the Placing bearing bases on a surface area of the water rebate prevents the water rebate side with its raised, internal fold edge and concealed by the neighboring roof covering panel penetration of precipitation into the roof space, which is the basic purpose of each water rebate side corresponds
  • Each of the roofing panels for ventilation has an inner and at the top of its head an outer head rib and on the underside of her foot an inner and outer foot rib, which are about to each other run in parallel.
  • the inner and outer head rib as well as the inner and outer foot rib are in their edge areas either rounded or beveled into a trapezoidal cross-sectional shape.
  • For a favorable runoff of precipitation To allow between the outer and inner head rib is the inner head rib on the water rebate side provided with a drainage opening adjacent.
  • the water fold is at its base of the roofing slab facing end also with a drainage opening to the water rebate side of the adjacent Roof covering plate provided. This can penetrate precipitation from the area between the outer and inner head rib to the water seam side and from there through the drainage opening there flow away from the water rebate side near the foot to the roof covering plate adjoining it in the direction of the eaves.
  • the roof covering plate for ventilation is on its underside near its head two protruding lugs for mounting on a roof batten and in the adjoining one, just before the ribs area to ensure a correspondingly high load capacity with both lengthways and with provided transverse stiffening ribs. From the inside of two stiffening ribs running parallel to the longitudinal axis branch three transverse expansion rib pairs towards each other at different heights from, the one longitudinal stiffening rib below the water seam side and the other approximately in Center area of the bottom is arranged.
  • stiffening ribs are not only for reasons of strength, but also against a fluidic background of the ventilation, because this means the underside of the roof covering slab in the area of the top rebate smooth and without dents which hinder the ventilation flow is trained. This smooth area therefore has a low-resistance air guiding function for those from the attic air to be extracted.
  • the roof covering plate according to the invention corresponds in size and circumferential contour to a conventional roof covering plate and is either together with other identical roofing slabs of this type for ventilation or can be installed with conventional roofing tiles of the same circumferential contour.
  • These roofing tiles for ventilation are made of clay and are in a conventional pressing process in the corresponding under and Manufactured upper forms. In principle, however, it is also possible to use roofing panels of this type in a pressing process to manufacture with concrete. because the longitudinally folded surface is relatively smooth and the underside with relatively flat, is conical shapes.
