Description of the invention

The subject of the invention is a ventilating element of a ridge or a corner of a roof, consisting of a central strip fixed on its batten and connected to it - on both sides - of side strips, consisting of strips with an air-permeable surface adjoining the central strip and connected to them external belts.

Roof ventilation elements are used to seal the void existing on both sides of the ridge between the batten and the roof covering, and to eliminate the possibility of rain, snow, dirt and insects penetrating into the building, and at the same time to effectively ensure ventilation of the roof and protect the elements. its structure against damage as a result of putrefactive processes.

DE 4 001 766 C2 discloses a ventilation element mounted on a ridge, the side parts of which are made of non-woven or woven fabric, and their shape and dimensions cannot be changed during assembly. A significant disadvantage of this known ventilation element is the inability to seal the space between the roof covering and the ridge batten if the widths of these spaces are different from the widths of its side parts.

From the German utility model description DE GM 295 01 242.0, a roof sealing strip is known, the middle strip of which is provided with grooves of a predetermined length, by means of which it is connected to the side stripes, which enables the strip width to be adapted to different roof batten widths.

From the German description of the utility model no. DE GM 94 16 291, a sealing tape for a ridge or a roof corner is known, made of air-permeable foamed plastic, which with its central part is mounted on the ridge beam, and with its side parts on the adjacent panels. roof covering. The sealing strip is provided in its central part with a reinforced strip which joins its side edges with its side parts. The side portions of the strip are formed of two air-permeable strips made of open-pored foamed plastic and of two reinforced corrugated strips adjoining them along their outer edges and provided with an adhesive layer on the surface adjacent to the roof covering. The sealing tape is covered from the outside with ridge tiles, maintaining a free space between the tape and ridge tiles. The tape seals the ridge area against rainfall, and at the same time ensures ventilation of the under-roof space.

DE 196 27 750 discloses a roofing element made of metal or plastic for ventilating the free space between two roof slopes or in the eaves area, and consisting of a central gutter to which both of the roof gutters are attached. the sides of the boards are fixed to the roof truss. T-slats are welded to the upper surface of each plate, on which the roof covering rests. The gaps between the battens ensure ventilation of the space between the roof covering and the truss. In the design for the eaves, the element consists of a similar plate mounted on the lower part of the eaves support structure and is extended with the part bent downwards towards the gutter. A ventilation bar in the form of an I-section is attached to the slab, the web of which has vertical slots for air flow. The roofing sheets rest on this ventilating strip.

EP 0 341 343 discloses a sealing tape for a ridge or a roof corner, provided with an air-permeable middle strip overlapping a ridge beam or a roof corner, and with two side strips connected to it along its edges, with their outer edges. parts are mounted on the roof cladding panels. The middle band is made of an air-permeable, non-wetted non-woven fabric, while the side bands are made of soft, stretchy polyisobutylene in which is embedded an expandable metal mesh with high elongation in the longitudinal direction and much less in the transverse direction. The mesh also extends to part of the center lane. The nonwoven fabric of the middle strip is glued with its side edges overlapped on the outer side strips provided with a self-adhesive layer, covered with a protective peel-off foil.

GB 2 155 516 A discloses a ventilating element with folds forming a kind of grooved walls to which other components are attached.

PL 197 299 B1

Also known from the prior art are ventilation elements for a ridge or a corner of a roof, constituting a one-piece structure made of a soft, foamed plastic with open pores and of equal dimensions. These elements, combining the roof covering and the ridge batten, cover the gap formed between the roof and the batten, and ridge tiles are placed above them, pressing their edges against the roof covering surface. It happens, however, that the ventilation element does not seal the gap between the batten and the roof covering accurately, for example due to its incorrect attachment, or the air permeable surface of the element adheres too tightly to the batten or to the roof covering, reducing the ventilation efficiency.

In roof structures, solutions are more and more often used in which the distances between the ridge batten and the roof batten are different, resulting in variable widths of the roof gap. In order to eliminate this problem, ventilation elements of different sizes, in particular of different widths, are used, which of course increases the workload for fixing them and the manufacturing costs, and thus also the costs of sealing the roof.

The object of the invention is to provide such a structure of the ventilating element which enables the sealing of the space between the ridge batten and the roof covering in a simple manner for different widths of this space, and at the same time ensures proper ventilation of the roof.

This aim is achieved by the ventilation element of the ridge or roof corners according to the invention, which is characterized in that the side stripes are provided with air-permeable longitudinal folds located at the edge of the runway in a direction parallel to the ridge axis, for stretching and sliding the ventilation element in the direction of transverse to the ridge.

The longitudinal fold of the side band preferably forms a trailing edge of the roofing material at the lower edge of the fold.

The air-permeable belt is preferably made of a flexible mesh, reinforced by covering it with a thin foil.

The air-permeable belt is preferably made of an elastic non-woven material.

The reinforcement foil covering the mesh is preferably made of light metal, for example aluminum or plastic.

The belt-forming mesh with an air-permeable surface is preferably made of plastic or metal.

The lower surface of the middle strip and / or the outer strip is preferably covered with a self-adhesive layer.

The above-described ventilation element of the ridge or the corner of the roof according to the invention enables the correct sealing of the space between the ridge batten and the roof covering, having different widths, because its longitudinal folds allow it to be adapted to the dimensions of the gap, and at the same time ensure that the appropriate air permeable surfaces and cross-sections, necessary for proper roof ventilation. In the case of a small distance between the roof batten and the ridge batten, it is possible to reduce the dimensions of the ventilation element in the lateral direction by pulling the folds. The deviations in the dimensions of the gap, resulting from the use of patches of different widths and the inaccuracy of their fixing on the roof structure, therefore do not affect the proper operation of the ventilating element.

The ventilation element of a ridge or roof corner according to the invention is shown in an exemplary construction in the drawing, in which: Fig. 1 shows a ridge equipped with a ventilation element according to the invention in a perspective view; Fig. 2 shows a perspective view of the ventilating element according to Fig. 1, rolled up before being attached to the roof, and Fig. 3, a different design of the ventilating element according to the invention, in cross-section.

The ventilation element 10 of the roof ridge shown in Fig. 1 consists of a central strip 11 and side strips 12 connected to it on both sides. The middle strip 11 abuts with its lower surface 13, preferably provided with a self-adhesive layer, against the upper surface 14 of the batten 15 and it is attached to it by gluing.

Connected thereto on both sides of the center strip 11 are belts 16 with an air-permeable surface forming part of the side belts 12. The belts 16 are provided on both sides with folds 18 and 19, parallel to the longitudinal direction 17 of the element 10. The folds 18 and 19 allow the belts 16 to be stretched or tightened with an air-permeable surface in the transverse direction. The edges of the folds 18 and 19 are preferably rounded, with the folds themselves forming a pleated structure allowing them to slide apart or slide together. Folds 18 and 19 can also be of the form

PL 197 299 B1 of the wave. During stretching, the angle between the adjacent surfaces of the folds increases, thus eliminating the possibility of creating unfavorable internal tensions in the material. Increasing the number of folds 18 and 19 makes it possible to increase the extent of the stretching or tightening of the accordion formed by them which obscures the space between the batten 15 and the roof covering 20, irrespective of the width of the space.

The roofing 20 shown in Figures 1 and 2 is made of tiles laid on battens 21 and 22 fixed to the rafters 23 and 24. The ridge batten 15 is fixed by a bracket 25 over the upper edges of the rafters 23 and 24.

The side stripes 12 of the ventilation element 10 consist of two adjacent strips, namely: a strip 16 with an air-permeable surface, and an external strip 26 connected to it, also provided with longitudinal folds 28, 29, 30, enabling the change of the width of the element. of a ventilating element in the transverse direction 27 of the ventilation element 10. The outer strip 26 is also provided with folds, but transversely parallel to the transverse direction 27 and allowing the surface of the ventilation element 10 to be perfectly matched to the contours of the roof.

The number of longitudinal folds 28, 29, 30 may of course also be greater, allowing the outer flange 26 to be stretched like accordions to position its surface parallel to the roof covering 20. The lower edges of the fold wall 30 form a trailing edge 32 facing the ridge 31, preventing the penetration of snow or moisture from the roof covering 20 into the air-permeable strips 16.

The air-permeable surface of the strip 16 is made in the form of a mesh of elastic plastic or metal fibers, whereby it is possible to easily change the shape of the surface of the strip 16 to fit the void space between the batten 15 and the roof covering 20. The belt 16 may also be made of non-woven material.

In order to increase the durability of the ventilation element according to the invention and its resistance to strong winds, it is advantageous to reinforce the web 16 by covering it with a thin foil of light metal or plastic.

The space 33 between the ridge tiles 31 and the venting element 10 forms an ascent sphere for the air flowing through the permeable surfaces of the strip 16 from the underroof space and for the air flowing in a direction transverse to the ridge.

An air flow from the windward side also flows into the space 33, taking with it the air ventilating the roof space. Other streams are deflected by the ridge tiles 31 and create a negative pressure on the leeward side that sucks the air under the ridge tiles, ensuring proper circulation and proper ventilation of the roof.

Effective ventilation of the inside of the roof is achieved when the air flow flows through the space 33 in the transverse direction 27.

Figure 2 shows the ventilation element 10 ready for transport.

The ventilation element 10 should be fixed to the ridge batten essentially symmetrically by gluing the center flange 11, but it can also be attached asymmetrically, for example to seal and ventilate only one slope of the roof.

When mounting the ventilation element 10 on the roof structure, the side bands 12 are rolled out to seal the space between the ridge batten 15 and the roof covering 20. In Fig. 2, the individual parts of the side strips 12 are laid flat, so that the element 10 can be rolled up into a roll. Since the element 10 in the exemplary construction according to the invention is made of plastic, it is possible to easily stretch the folds and then, during assembly of the element, to pull them back again. The folds 18, 19 and 28, 29 and 30 are formed during the fabrication of the element 10, but may also be separately connected to the center flange 11 and the flange 16 to the air permeable surface of the roofing roofer. The height of the folds 28, 29 and 30 should be matched to the size of the space 33 under the ridge tiles to ensure a suitable cross-sectional area for the flowing air.

The ventilation element 40 shown in Fig. 3 consists of a central strip 41 connected to the side stripes 42. The middle strip 41 is flat and made of a different material than the side belts 42, which consists of two parts, namely: a strip 43 of an air-permeable and air-impermeable outer strip 44, both of which are made of different materials and joined together by gluing.

PL 197 299 B1

The accordion-shaped strip 43 with the permeable surface allows the width of the element 40 to be varied in the transverse direction 45 by stretching or sliding it. The outer strip 44 is provided with transverse folds 46, thanks to which it is possible to precisely adjust the element 40 to the surfaces of various roofs. The trailing edge 47 eliminates the penetration of snow and rain into the inner space of the roof.
