Definitions

  • the invention relates to a ventilation element for the ridge or ridge area of roofs according to the preamble of claim 1.
  • a ventilation element for roofs is known from EP 0 807 726 A3, which forms a fan cap to be arranged in the ridge region, on the edge regions of which strip-shaped sealing elements protrude.
  • These sealing elements are made of an elastic material, so that a shape adaptation to the respective adjacent roof tiles is possible.
  • Such roof ventilation elements are usually made of plastic, whereby the formation of algae, lichens and moss can not be effectively suppressed.
  • the vast majority of ventilation elements have now just under the first hipped covers arranged their ventilation openings. This can often rainwater and. Not tightly closed or defective ridge-ridge cover Flying snow penetrate unhindered and moisture damage occurs in the roof structure or roof structure, which are only discovered when it is usually already too late.
  • the invention has for its object to provide a ventilation element for the ridge or ridge area of roofs, which consists of a flexible material and preventively against unwanted growth by algae, lichens or the like is effective and prevents the penetration of moisture as well.
  • the ventilation element is at least partially provided with metallic surfaces, which may for example consist of copper, zinc or titanium. Such metal surfaces have a good leaching against algae formation and other vegetation by means of ion rinsing, so that thereby a growth of the roofing material is restricted or prevented.
  • the ventilation element is preferably made of a woven, knitted or produced in a different continuous process, reticulated or mesh-like base material bcstcht from thin Mctalldrähtcn or metal filaments. But it is also possible to use a fabric in the central region of the ventilation element, adjoin the side edges of metal strips or metal filaments or other metallized sealing elements.
  • the fabric used in this case can be coated like a tarpaulin in order to achieve a sufficient resistance to environmental influences.
  • the ventilation element is made of a plastic base material
  • the laterally projecting sealing elements may have metallized surfaces in order to achieve the desired protection against unwanted growth.
  • any other flexible base material in particular natural base materials, Use find such as jute, coconut or wool materials. It is important in any case that the ventilation areas where there is a risk of fouling, are provided with appropriate metallization or with additional metal elements such as copper, zinc or titanium.
  • the material may be impregnated with a suitable agent for protection against rotting.
  • the ventilation element is formed from a metal wire mesh or a mesh fabric or from a mesh or knitted fabric made of thin metal threads, then it is particularly advantageous to depress the ventilation element by means of rolling to a predetermined thickness.
  • the material can be compressed to form a longitudinal groove, so that this longitudinal groove has a corresponding material compaction and is particularly well suited for nail-fixing to the ridge or burr lath.
  • a development of the invention provides that in the ventilation element punched ventilation holes are provided, which are enclosed by means of eyelets.
  • the eyelets ensure that the wires or threads that make up the ventilation element are securely held even in the area of the ventilation holes and do not cause frayed burrs there. Also, these rings prevent clogging of the vents.
  • Such holding elements may be wire brackets, which support the bulge of the ventilation element in the central region and press the side edges of the ventilation element into the indentations formed by the adjacent roof tiles in the outer edge region. If such holding elements used, the ventilation element can be made of a correspondingly easily flexible material, since the holding elements give the required dimensional stability.
  • the ventilation elements may protrude sealing strips, which are weighted with balls or other parts to ensure a secure concern of the sealing strips on the surface of the roof tiles.
  • the parts used may be made of metal, ceramic, glass or plastic, with suitable metallic surfaces in turn to prevent growth in the ventilation area and the roofing material are advantageous.
  • the ventilation element according to the invention is so flexible that it can be rolled up or folded in order to facilitate the transport and also the handling of the ventilation element.

  • the folds, notches or undulations not only facilitate the depression of the edge area, but also a longitudinal deformation in which, for example, the folds can be slightly pulled apart or even compressed, thereby achieving an optimal seal.
  • the wrinkling may be a so-called Leporello deformation.
  • the deformable material formed as edge strip It is particularly advantageous to stabilize the outer edge of the deformable material formed as edge strip by an additionally attached aluminum strip or another, deformable metal strip.
  • This metal band can be on the be deformed edge strips glued or is preferably sewn thereto by means of a metal wire.
  • the deformable material itself can also be sewn or glued with a central support element, which connects both edge regions of the ventilation element with each other.
  • all parts of the ventilation element are sewn together by means of metal wire, since this type of attachment gives great manufacturing advantages and is also completely insensitive to weathering.
  • the metal wire used in this case stabilizes the edge region of the ventilation element which is adapted to the contour of the respective roofing by deformation.
  • the deformable material may for example consist of copper, stainless steel or another metal.
  • the band used for stabilization may also be made of metal, for example aluminum.
  • the outer longitudinal edges of the edge strips may contain an inset or a deformable wire lying in a bead, which serves to stabilize the respective longitudinal edge.

At the same time, these edge strips have a very good ventilation function and prevent the penetration of snow and driving rain.
  • the connection of the edge strips with the central support element can be done by gluing, sewing or by means of brackets.
  • the entire ventilation element may have a transverse to its longitudinal direction Leporello deformation or other fold or notch, which can be produced in a deformation process by means of a molding roll.
  • Leporello deformation allows the fabricator to stretch or push together the sealing strips as needed to obtain the best possible seal against drift snow and driving rain.
  • the ventilation part designed as a metal wire mesh or mesh fabric preferably extends only at the left and right at the lower end of the ridge cover and is connected to a closed central metal support element, for example a metal foil, which extends below the ridge cover.
  • the fine-meshed grille does not let any driving rain or flying snow through.
