Definitions

  • the invention relates to a ridge sealing and ventilation element, which is to be attached under ridge stones or possibly other ridge cover parts on a ridge screed and, after being placed on it, describes a curvature surface and has the raised support for the inner surfaces of the ridge stones, is lined with push-in edge strips below its outer edge regions and above its curved surface has distributed air passage openings which are arranged in areas outside the supports.
  • Such a ridge sealing and ventilation element is known from German Offenlegungsschrift 3 533 822.
  • This element which describes a vaulted surface after laying, is nailed directly onto the ridge plank over the entire length.
  • On the outward-facing surface there are individual, circular supports and mirrored round ventilation openings on both sides of the ridge screed, the ventilation openings being surrounded by a bead.
  • the arched area is lined with push-in edge strips at the outermost edge areas.
  • the above-mentioned ridge sealing and ventilation elements are attached between a ridge stone made of concrete or ridge tile made of fired clay and the ridge screed in order to absorb the weight of the ridge stones lined up and to ensure ventilation below the ridge stones in the ridge area.
  • An improvement of the ridge sealing and ventilation elements is aimed at reducing the material consumption for the installation of such elements, i.e. to use a relatively thin material, the ventilation properties of the element compared to the known element should be at least equal, but if possible should be improved.
  • the object is achieved in that the supports are designed as individually arranged fins with their side surfaces transverse to the direction of travel, which start at a distance from the ridge line, are arranged along the element side edges and protrude beyond the element side edges.
  • the elements are preferably made of plastic, for example polyvinyl chloride or polyethylene. However, it is not out of the question to also form elements from sheet metal.
  • the fins can be made from solid material or else as an inverted hollow body, preferably in one piece with the remaining material of the element.
  • the ridge sealing and ventilation element lies flat immediately after manufacture and only forms a vaulted surface under the load of the ridge stones.
  • the fins are preferably at a distance from the ridge line and are also cut somewhat obliquely, with two There are buckling areas that run between the fins and the ridge line.
  • the fins are generally arranged in rows, at least some of the fins also being able to be arranged in comb-like rows which extend over the curvature of the element.
  • the bearing load of the ridge stone is distributed particularly well over the surface. It is also possible to arrange rows of such fins on beads running over the curvature of the elements, so that a particularly stable arrangement is given.
  • a further embodiment is to step down at least one of the side edges of the element in a step-like manner, the steps extending in the ridge direction.
  • This design has the advantage that along the step edges each later or during manufacture with the help of cutting tools, one strip after the other can be cut off one step at a time, so that wider, narrower elements can be produced, which are therefore suitable for the corresponding ridge stones are easily adapted. Accordingly, only one tool is required for production; warehousing is also significantly cheaper if only a broad form is specified.
  • the ventilation slots are designed as incisions, which are known to be mirror images on both sides of the ridge line, thus allowing good air purging in the immediate ridge area.
  • the ventilation openings usually have an elongated rectangular shape, with the long side lying along the ridge.
  • the ventilation openings are surrounded in a known manner by an edge web or by a round bead, so that condensed water or indented rainwater is not can flow into the ventilation opening.
  • These edge strips can also be designed so that they have a bow-like shape at the top, at which the water can not build up.
  • the ventilation openings can also be arranged in hollow bases which are set apart from one another and lined up along the ridge blocks.
  • FIG. 1 shows a ridge sealing and ventilation element in a first embodiment, reference number 100.
  • the element is arranged under a series of ridge stones of the usual shape. If necessary, other ridge cover parts can also be attached between the ridge stone and the element 100, which however, essentially do not change the task and function of the elements 100 or 200 or 300 to be described below.
  • ridge bricks fired clay ridge bricks in various widths and curvatures can also be used. It is also not excluded to use the element to cover the ridges.
  • the ridge sealing and ventilation element 100 is made from a colored, 1-3 mm thick plastic film, for example polyvinyl chloride, or from a corresponding, injection-molded plastic material, e.g. B. polyethylene. It has a modular structure, the module length being M and, in the present case, each comprising a bead 7, 8 running over part of the curvature.
  • a single element 100 may include two, four, or more such modules.
  • the element is lined with push-in edge strips 5, 6, which lie sealingly on the ridge-side roof covering panels and provide extensive sealing against water and dust there.
  • the arched element 100 has beads 7, 8 running at a distance of one module length M each over a part of the curvature, which are interrupted in the apex region of the element and provide stiffening in the other regions. Furthermore, numerous supports 10, 11 are attached to the bead, the side surfaces of which are transverse to the ridge direction. These supports are referred to as "fins” because they have the shape of aerodynamically shaped fin-like structures and at the same time the function of the support, together with the underneath bead 7, 8.
  • the fins 10, 11 are arranged in comb-like rows on top of the beads 7, 8 and, in the present case, are designed as inverted hollow bodies, this shape being selected in particular when the ridge sealing and ventilation elements 100 are produced using the deep-drawing process.
  • the fins 9 are designed as comb webs resting on the arch surface.
  • the fins 9 project beyond the element sides and are at a distance from the ridge line, so that the element 100 can be bent or arched around the ridge line when the heavy ridge stones lie on it.
  • a further feature of the ridge sealing and ventilation elements 100 is formed by ventilation openings 16, 17.
  • the ventilation openings 16, 17 are each formed in pairs, each assigned to a module length, as a mirror image on both sides of the ridge line (-.-.-.). In the present case, these are roughly rectangular openings, the longer side of which runs parallel to the ridge.
  • the ventilation openings 16, 17 are surrounded by an upstanding bead 19, which prevents water from flowing into the openings 16 and 17, respectively.
  • FIG. 1 shows two embodiments of such ventilation openings. While the opening 16 is a simple, punched-through opening with an edge bead, the ventilation opening at the opening 17 is surrounded by a protruding edge 18 toward the ridge side. Furthermore, the lower edge is formed together with a bottom in such a way that a trough is formed which has its low point approximately 2-6 cm below the upper arch surface.
  • the bottom 21 and / or the edges 18 are provided with ventilation perforations 22, 23, which ensure adequate ventilation in the ridge area. Seen in the longitudinal direction, three or four such perforations 22, 23 can be seen be provided.
  • FIGS. 2 and 3 show a further curved ridge sealing and ventilation element 200, which is to be arranged under a row of ridge stones 1 of the usual shape.
  • the ridge sealing and ventilation element 200 is made from a colored, 1-3 mm thick plastic film or from a corresponding, injection-molded plastic material. It has a modular structure, the module length being M and this in turn corresponding to approximately half the ridge length. A single element 200 can accommodate two, two and a half, or three such modules. When laying the element is preferably arranged overlapping. For this purpose, it is nailed onto the existing ridge screed 2. The ridge stones are then fastened with ridge brackets (not shown), as is known in the conventional ridge laying technique.
  • the element is lined with push-in edge strips 5, 6, which lie sealingly on the ridge-side roof covering panels and provide extensive sealing against water and dust there.
  • the arched element 200 has beads 7 ', 8' which run over the curvature at intervals of half a module length M and which provide stiffening. Furthermore, numerous fins are attached to the convexly curved outside, the side surfaces of which are transverse to the ridge direction. In the present case, the fins are designed as inverted hollow bodies, this shape being chosen in particular when the ridge sealing and ventilation elements 200 are produced using the deep-drawing process. The fins are made of solid material be made when the element 200 is injection molded.
  • the fins 10 are partially arranged in comb-like rows 14 which extend over the curvature of the element 200.
  • the fins 9 are arranged along the edge of the element in order in particular to facilitate the air entry in the edge area when the ridge tiles are in place; they also protrude outward beyond the edge.
  • the edge regions 3, 4 of the ridge sealing and ventilation element 200 shown are stepped, steps 15 each having a height and width of approximately 8-20 mm. These gradations enable a cut to be made along a step edge, this cut being made by the manufacturer, but also later, and thereby resulting in narrower elements which are adapted to correspondingly narrower ridge stones.
  • Ventilation openings 16 ', 17' are each formed in pairs, each mirroring the half length of the module, lying on both sides of the ridge line. These are roughly rectangular openings, the longer side of which runs parallel to the ridge.
  • the ventilation openings are surrounded by an upstanding bead 19, which prevents water from flowing into the opening 16 'or 17'.
  • the edge bead is bulged or shaped toward the ridge like a ship's bow, preventing water from being stowed. However, the edge web is only dimensioned so high that the ventilation is otherwise not hindered.
  • Further fins 11 are each arranged directly in the apex area and take up the weight of the ridge stone in this area.
  • FIGS. 4a and 4b A ridge sealing and ventilation element in a third embodiment, reference number 300, is shown in FIGS. 4a and 4b.
  • the element 300 is arranged under a row of ridge stones of conventional shape. While it initially has a flat shape after production (FIG. 4b), a curved surface is formed under the load of the ridge stones.
  • the element 300 is formed from a colored, 1-3 mm thick plastic film, as in the other exemplary embodiments. It is also constructed in a modular manner, the module length being M and, in the present case, each comprising a hollow base 30 arranged in the ridge area.
  • the hollow base has a width of slightly more than the ridge plank width. In its upper side, ventilation openings 16 are cut, each of which runs in mirror image on both sides of the ridge line.
  • spacer knobs 31 are placed on the four corners of the hollow base 30, which protrude upwards.
  • the inside of the ridge covering element lying on it rests in the region of the apex on these spacer knobs 31.
  • spacing cams 34 are also provided between the ventilation openings 16.
  • the hollow bases are each connected to two webs 32 running in the ridge direction.
  • element 300 is provided on its sides with fins 9 which are oriented towards the apex.
  • the area between the bevel 33 and the outside of the hollow base, denoted by "K”, represents a kink area which is not so heavily loaded when the ridge stones lie on it and which thus produces the arch surface which the ridge sealing and ventilation element 300 is compatible with 30 the domed ridge stones.
  • the fins 9 protrude laterally beyond the outer edge of the wing parts of the element. This prevents the heavy ridge stones lying on top from resting on the outer edge and interrupting the cross-air flow.
  • the element according to FIGS. 4a and 4b can advantageously be injection molded or deep-drawn in plastic tools that are easy to create, a plane shape according to FIG. 4b initially being produced, which bulges downward only in the application. There is no separation of the air flow in the area of the ridge screed, since the cams or knobs standing up and down allow an unimpeded air flow to take place transversely to the ridge batten.
