Description

The present invention relates to a fastening profile, a connecting element and a system for ventilation profiles for ventilated facades of buildings.

Ventilation profiles for ventilated facades are used, for example, to achieve protection against the ingress of birds, insects or other small animals in the roof connection area, in the floor or in the lateral connection area, in the window sill connection area, in the lintel area or in the lintel area of the façade, while ensuring adequate ventilation ,

It is known to connect such ventilation profiles directly to a building section, such as a wall or ceiling section, or to connect the ventilation profile with a attached to the building section, the facade supporting substructure. Furthermore, such ventilation profiles can be attached via additional fastening profiles to a building section.

A disadvantage of known ventilation profiles that for different width dimensions of the ventilation gap to be covered by the ventilation gap a corresponding plurality of different ventilation profiles must be maintained, resulting in significant storage costs. Furthermore, the assembly of the ventilation profile is difficult if the building section on the one hand and the substructure or the facade on the other hand are not over their entire length in a constant relative arrangement to each other, but, for example, wall unevenness to a variation of the width of the ventilation gap over the length of the building section to lead. In this case, it is also not possible to mount the ventilation profile without constraint, d. H. it is unavoidable that in the assembled ventilation profile internal stresses occur, which adversely affect the mechanical stability of the ventilation profile and the reliability of its attachment.

Furthermore, there is the problem with known ventilation profiles that thermal expansion of the ventilation profile can lead to distortion of the ventilation profile or associated with the ventilation profile substructure, which adversely affects the stability of the overall arrangement.

The object of the invention is to provide a fastening profile, a connecting element and a system for a ventilation profile for ventilated building facades, which is equally usable for different width dimensions of the ventilation gap to be covered by the ventilation gap and regardless of the specific installation situation, especially in one on the Length of the ventilation gap z. B. due to wall unevenness varying width of the ventilation gap, a simple and quick installation of the ventilation profile allows, which also leads to a long-term stable and reliable attachment of the ventilation profile.

According to a first aspect of the invention, the object is achieved by a fastening profile for fastening a ventilation profile for ventilated facades of a building on a building section, wherein the fastening profile is elongated in a longitudinal direction and a mounting leg for attachment to the building section and a connecting leg for connection to the Has ventilation profile. The connecting leg has at least two longitudinally spaced coupling sections, wherein in each coupling section at least two mutually spaced coupling positions are defined, in which the connecting leg can be coupled in each case with a connecting means for the ventilation profile.

In this embodiment of a fastening profile, a given ventilation profile can be connected to the fastening profile in each of the coupling sections which are spaced apart in the longitudinal direction of the fastening profile in at least two different, mutually spaced coupling positions.

This makes it possible to adjust the relative arrangement of the ventilation profile and mounting profile and thus ultimately the width of the ventilation gap covered by the ventilation profile by appropriate selection of the coupling positions. Since this adjustment is made simply by selecting and using the appropriate coupling positions already defined in the fastening profile, it is possible in particular to dispense with expensive pre-drilling of holes in the fastening profile during the adjustment, which considerably simplifies the assembly as a whole. In principle, of course, a drilling step, for example, to adapt an existing, a coupling position defining hole of the fastening profile to a connecting means with a larger diameter. The fastening profile thus enables the use of the same ventilation profile in different installation situations, which differ, for example, with regard to the width dimension of the ventilation gap to be covered by the ventilation profile. As a result, the storage costs for appropriate, consisting of mounting profile and ventilation profile ventilation systems are reduced.

The ability to couple the ventilation profile in each attachment portion of the fastening profile in a different coupling position with the mounting profile, it is also possible to compensate for a variation in the width of the ventilation gap to be covered over the longitudinal extent of the ventilation gap and adapt the ventilation system to such a varying width. As a result, a simple and constraint-free mountability of the ventilation profile and optimum coverage of the ventilation gap is achieved in any installation situation.

Advantageous embodiments of the invention are described in the subclaims, the description and the drawings.

A ventilation profile used with the fastening profile according to the invention may, similarly to the fastening profile, also have a plurality of coupling sections spaced apart from one another in the longitudinal direction of the ventilation profile, in each of which a plurality of mutually spaced coupling positions for the connection means are defined. The coupling sections of the ventilation profile with the coupling positions can be formed in particular by the ventilation holes of the ventilation profile itself, which are suitable for receiving a connecting means for connection to the fastening profile. In this case, the possibility of selecting one of a plurality of coupling positions of the ventilation profile and one of a plurality of coupling positions of the fastening profile for the connecting means in each coupling section of the ventilation profile and fastening profile further increases the variety of available relative positioning of ventilation profile and fastening profile. In this case, an at least approximately stepless adjustment of the relative positioning of the ventilation profile and fastening profile in each coupling section can be made possible, thereby adapting the ventilation system to a given width of the ventilation gap and / or compensating for a variation of this width over the length of the ventilation gap.

In each coupling section of the fastening profile, an arbitrary multiplicity of continuously successive coupling positions is preferably defined, which comprises the at least two coupling positions of the coupling section. As a result, a stepless adjustment of the relative positioning of the fastening profile and ventilation profile over at least one region is achieved.

According to an advantageous embodiment of the fastening profile according to the invention, the at least two coupling positions of a coupling portion are defined by the spaced apart ends of an elongate opening of the fastening profile provided in the coupling portion. In this case, also define all disposed between the two ends of the elongated opening positions of the elongate opening a coupling position for the connecting means, so that at least partially a continuously adjustable relative positioning of mounting profile and ventilation profile is achieved. The elongate aperture may be formed as a slot, which in particular has a width substantially constant over its length.

Preferably, the at least two mutually spaced coupling positions of a coupling portion in a direction transversely and in particular at least approximately perpendicular to the longitudinal direction of the fastening profile are arranged one behind the other. In this embodiment, the relative positioning of fastening profile and ventilation profile in the direction transverse to the longitudinal direction of the fastening profile can be selected by appropriate selection of the coupling position and thus the ventilation system can be adjusted specifically to a given width of the ventilation gap to be covered by the ventilation profile. The two coupling positions preferably lie one behind the other in a line running essentially perpendicular to the longitudinal direction of the fastening profile, but may also be offset relative to one another in the longitudinal direction of the fastening profile.

In the embodiment described above, the at least two coupling positions of a coupling section can be formed, for example, by a slot oriented transversely with respect to its longitudinal direction and in particular perpendicular to the longitudinal direction of the fastening profile.

An advantageous embodiment of the fastening profile according to the invention provides that the at least two coupling positions have a spacing of between 3 and 50 mm, preferably between 5 and 30 mm and particularly preferably between 10 and 20 mm. If the fastening profile is used with a ventilation profile, the ventilation holes are suitable for performing the connection means for connecting the ventilation profile and mounting profile, can be bridged by the at least two coupling positions of the fastening profile, for example, the distance between two adjacent rows of ventilation holes of the ventilation profile, so that over several rows of ventilation holes the ventilation profile across a finely graded and preferably stepless adjustability of the relative positioning of the ventilation profile and mounting profile is achieved.

According to a further advantageous embodiment of the invention, it is provided that at least one and in particular each of the at least two coupling sections can be coupled in its two coupling positions with a pin-like connecting means. Such a pin-like connecting means preferably engages through an opening of the fastening profile and / or the ventilation profile in order to produce a secure connection between the ventilation profile and the fastening profile. The connecting means may have a substantially round cross-section. In particular, the connecting means may be formed by a rivet, a screw or a connector.

Advantageously, the fastening profile is designed as an L-profile, wherein the fastening leg and the connecting leg form the two legs of the L-shaped cross-sectional shape of the fastening profile. The mounting leg can serve in particular for surface contact with the building section, whereby a particularly reliable connection between the building section and mounting profile is achieved. The connecting leg can be designed for surface contact with the ventilation profile, as a result of which a particularly reliable connection between the fastening profile and the ventilation profile is achieved.

The fastening leg of the fastening profile can have at least one hole with a round cross-section and / or a slot for a fastener fastening the fastening profile to the building section. As a result, a reliable attachment to the building section can be achieved. A slot also facilitates the adjustment of the mounting profile on the building section, as it allows a subsequent displacement of the mounting leg relative to a arranged in the slot fasteners until the final attachment of the mounting leg. As a fastening means, for example, a pin-like fastening means, preferably serve with a substantially circular cross section, for example, a rivet, a screw or a connector.

The fastening profile may have one or more beads, whereby a stiffening of the fastening profile can be achieved. Furthermore, the material of the fastening profile can be provided with an embossed structure, for example a bead structure, a fish skin or the like.

The fastening profile preferably comprises a metal material, for example an aluminum material, a stainless steel material or a steel galvanized material, or consists thereof. The attachment profile may also comprise or consist of a plastic material.

The fastening profile according to the invention is particularly suitable for fastening a ventilation profile for ventilated facades in the bottom connection area and in the window or lintel area of a facade. Accordingly, the fastening profile can be fastened to a bottom wall section or a window or lintel section of the building. In principle, the fastening profile is also suitable for fastening a ventilation profile in the roof connection area, in the lateral connection area or in the window sill connection area of the facade.

According to a second aspect of the invention, the above-mentioned object is achieved by a system for fastening a ventilation profile for ventilated facades of a building to a building section, comprising a longitudinally elongated ventilation profile with a plurality of ventilation holes and a longitudinally elongated fastening profile with a fastening leg for attachment at the building section and with a connecting leg for connecting the fastening profile with the ventilation profile, wherein the ventilation profile and the fastening profile in substantially parallel longitudinal alignment in at least two mutually spaced in the longitudinal direction coupling areas are coupled to each other, wherein the ventilation profile and the fastening profile in each of the at least two coupling regions in each case via a connecting means in at least two different, transversely to the common longitudinal direction voneinande r spaced relative positions can be coupled together.

In this embodiment of the system, the relative position of fastening profile and ventilation profile can be selectively adjusted by appropriate choice of relative positions used to connect the fastening profile and the ventilation profile and thus to the width of the ventilation gap to be covered by the ventilation profile or any variation of this width over the length of Adjust ventilation gap. As a result, the same system can be used in a wide variety of installation situations and mounted there at any time simply and without constraint.

The fastening profile can preferably be designed as an inventive fastening profile as described herein. The embodiments and advantages described herein with respect to the fastening profile according to the invention apply accordingly.

According to an advantageous embodiment of the system according to the invention, the at least two relative positions lie in a direction substantially perpendicular to the longitudinal direction of the fastening profile and oriented parallel to the connecting leg of the fastening profile oriented one behind the other. This makes it possible to achieve a particularly simple and targeted adaptability of the system to the width of the ventilation gap to be covered by the ventilation profile.

A further embodiment of the system according to the invention provides that the connecting leg of the fastening profile has at least two coupling sections spaced apart from each other in the longitudinal direction of the fastening profile, wherein in each coupling section at least two mutually spaced coupling positions are defined, in which the connecting leg can be coupled to a connecting means for the ventilation profile , The two coupling positions of a coupling portion of the fastening profile then allow the mutual arrangement of the ventilation profile and fastening profile in different relative positions.

Alternatively or additionally, the ventilation profile may also have at least two coupling sections spaced apart from one another in the longitudinal direction of the ventilation profile, wherein in each coupling section at least two mutually spaced coupling positions are defined, in which the ventilation profile can be coupled in each case to a fastening means for the fastening profile. The coupling sections of the ventilation profile with the coupling positions can be formed in particular by the ventilation holes of the ventilation profile itself, which are suitable for receiving a connecting means for connection to the fastening profile. Thus, the already existing ventilation holes can be used to couple the ventilation profile in different relative positions with the mounting profile. If in this embodiment of the ventilation profile additionally also the fastening profile has a plurality of coupling sections with a plurality of spaced apart coupling positions, these can serve in particular to further expand the achievable relative positions of ventilation profile and mounting profile and a finely stepped or in particular stepless adjustability of the relative positioning of the ventilation profile and mounting profile to ensure, due to the provision of the predefined coupling positions no pre-drilling of the ventilation profile or the mounting profile is necessary. It is preferred if a slot of the fastening profile and at least one row of holes of the ventilation profile, in particular substantially perpendicular, intersect when the fastening profile and ventilation profile are aligned substantially parallel with respect to their longitudinal direction and rest on one another in the coupling regions. By one or more such with the coupling positions of the fastening profile crossing rows of holes of the ventilation profile can be ensured that in each desired relative position of ventilation profile and mounting profile a ventilation hole of the ventilation profile is aligned with the slot of the fastening profile and thus a quick and easy connection without pre-drilling is possible.

According to a preferred embodiment of the invention, the ventilation profile has at least two juxtaposed and mutually adjacent rows of ventilation holes. In this case, the distance between the at least two coupling positions of a coupling portion of the fastening profile can be at least approximately as large as or greater than the distance between the two adjacent rows of ventilation holes of the ventilation profile. It is particularly preferred if in one and in particular each coupling portion of the fastening profile any number of continuously successive coupling positions are defined for coupling with a connecting means for the ventilation profile, which include the at least two coupling positions of the coupling portion. In this case, it is ensured that the ventilation profile can also be coupled to the fastening profile in any intermediate layer corresponding to the intermediate space between the two rows of ventilation holes, so that overall a stepless adjustability of the relative position of ventilation profile and fastening profile over a wide range is ensured. The arbitrarily many coupling positions of a coupling portion of the fastening profile can be defined in particular by an elongated opening of the fastening profile.

A further embodiment of the system according to the invention provides that the ventilation profile and the fastening profile are coupled to one another via a pin-like connecting means extending through a ventilation hole of the ventilation profile. The connecting means may have a substantially round cross-section and is in particular formed by a rivet, a screw or a connector.

The ventilation profile and the connecting leg of the fastening profile can rest in the region of their connection at least approximately plane-parallel to each other, whereby a particularly reliable connection is created.

An advantageous embodiment of the system provides that the width of a formed in the connecting leg elongated opening of the fastening profile corresponds at least approximately to the width of a ventilation hole of the ventilation profile. In this way, if the opening of the fastening profile and the ventilation hole of the ventilation profile are superimposed and Vertically crossing each other, a substantially square, through the ventilation profile and the fastening profile extending through opening are created, which is particularly well suited for receiving a connecting the ventilation profile with the fastening profile connecting means.

According to a third aspect of the invention, the object mentioned at the outset is achieved by a connecting element for connecting a ventilation profile for ventilated facades of a building with a substructure attached to the building, wherein the connecting element comprises a base section in which at least one fastening section for fastening the connecting element to the Substructure is formed, and at least one connecting portion for connecting the connecting element with the ventilation profile. In this case, the connecting portion of the connecting element has a neck section which extends from the base section in a longitudinal direction beyond the base section and engages through a ventilation hole of the ventilation profile and a holding section adjoining the neck section, the holding section being oriented in a direction transverse to the longitudinal direction protruding over the neck section.

Such a connecting element can be so coupled with a ventilation profile for ventilated facades, that the ventilation profile is mounted in its longitudinal direction relative to the connecting element displaceable on the connecting element.

The coupling of the ventilation profile with the connecting element can be carried out in a simple manner by inserting the holding section and the neck section in the longitudinal direction of the neck section through a ventilation hole of the ventilation profile and subsequently rotating the connecting element relative to the ventilation profile around the longitudinal axis of the neck section. In this case, the retaining portion projecting relative to the neck portion engages behind the ventilation profile in the area of the ventilation profile delimiting the ventilation hole and forms an undercut in the longitudinal direction of the neck portion with the ventilation profile and thereby limits movement of the ventilation profile in the longitudinal direction of the neck portion. The neck portion, however, can move freely in the ventilation hole in the longitudinal direction of the ventilation hole, so that a displacement of the ventilation profile in the longitudinal direction of the ventilation hole is ensured. The connecting element can then be fastened to the substructure via its fastening section. In this way, an effective support in the longitudinal direction of the neck portion of the ventilation profile is provided, wherein the ventilation profile remains displaceable simultaneously in the longitudinal direction of the ventilation hole of the ventilation profile relative to the connecting element.

This longitudinal displacement of the ventilation profile relative to the connecting element ensures that z. B. thermal expansion of the ventilation profile to no tension of the ventilation profile with the substructure, but only leads to a free longitudinal displacement of the ventilation profile relative to the connecting element. This considerably increases the long-term stability of the attachment of the ventilation profile to the substructure.

According to one embodiment of the connecting element according to the invention, the holding section projects beyond the neck section in two opposite directions, which are perpendicular to the longitudinal direction of the neck section. For example, the connecting portion may be substantially T-shaped, with the neck portion forming the vertical web and the holding portion forming the horizontal web of the T-shape. With such a connecting element, it is possible to reach behind the ventilation profile on two opposite sides of the ventilation hole receiving the neck portion and thus a particularly reliable retention of the ventilation profile on the connecting element.

A preferred embodiment of the connecting element according to the invention provides that the holding section on the one hand and the base section on the other hand each have one of at least two opposite and mutually facing end faces, which together define a bridged only by the neck portion gap of the connecting element. A ventilation profile accommodated in such a gap is mounted parallel to the longitudinal direction of the neck portion not only in the direction away from the base portion but also in the direction toward the base portion, whereby even more secure support of the ventilation profile is achieved. Preferably, the measured in the longitudinal direction of the neck portion width of the gap is adapted to the thickness of the ventilation profile, so that the ventilation profile is viewed in the longitudinal direction of the neck portion with little play or at least approximately free of play mounted on the connecting element.

A gap limiting side surface of the base portion of the connecting element can also serve as a stop for the connecting element during passage of the connecting portion through the ventilation hole of the ventilation profile and thereby facilitate the implementation process.

The minimum width of the gap measured in the longitudinal direction of the neck portion may, for example, be between 0.3 and 5 mm, preferably between 0.4 and 2.5 mm and particularly preferably between 0.6 and 2 mm.

An advantageous development of the connecting element provides that the connecting element comprises at least two connecting sections arranged at the longitudinal ends of the connecting element, wherein the at least two connecting sections have different dimensions from each other, preferably different widths of a gap, which the connecting sections in the manner described above form the base section. In this way, one and the same connection element can be used for various types of ventilation profiles, in particular for ventilation profiles with different thickness such as one hand ventilation profiles made of metal and on the other hand ventilation profiles made of plastic such. B. polyvinyl chloride. The two connecting portions of the connecting element can, however, in principle also be designed identically within the scope of the invention.

Preferably, the connecting element is formed from a flat material. The holding portion of the connecting portion then preferably projects substantially perpendicular to the longitudinal direction of the neck portion and parallel to a flat side of the connecting member via the neck portion.

According to an advantageous embodiment, the base portion of the connecting element has a longitudinal portion arranged between the fastening portion and the connecting portion, which has a lower rigidity with respect to a force directed in the longitudinal direction of the neck portion than the adjacent longitudinal portions of the connecting element. The connecting element can then absorb the resulting mechanical stresses elastically at a parallel to the longitudinal direction of the neck portion movement of the ventilation profile without warping the ventilation profile, the connecting element or the substructure occurs. This further increases the reliability of the connection between the ventilation profile and the substructure.

Preferably, the base portion of the connecting element is viewed in longitudinal section substantially S-shaped and has a first and a second longitudinal portion, which are connected by a transversely and in particular angled to the first and second longitudinal portion extending third longitudinal portion. Such an embodiment leads to a reduced rigidity of the connecting element in the region of the third longitudinal section.

An advantageous embodiment of the connecting element is achieved in that the first and the second longitudinal section are arranged substantially plane-parallel and offset in a direction oriented perpendicular to the two longitudinal sections offset from each other. It is preferred if the amount of the offset amounts to approximately half of the maximum width of the base section. This allows a particularly simple mounting of the connecting element on a surface of the substructure. Thus, it is possible to first attach the connecting element to the surface of the substructure in such a way that the offset direction is oriented parallel to the surface. If the connecting element is then rotated by 90 degrees to engage the holding section with the ventilation profile, the offset portion automatically comes to rest on the surface of the substructure and can be fastened there.

In the at least one fastening section, at least one hole with a substantially round cross section and / or at least one elongated hole can be provided for a fastening means to be connected to the substructure in order to ensure simple assembly and effective fastening of the connecting element. As a fastening means, in particular, a fastening means having a substantially circular cross-section and, for example, a screw, a rivet or a plug connector can be used.

A fourth aspect of the invention relates to a system for securing a ventilation profile for ventilated facades of a building to a substructure mounted on the building, comprising a ventilation profile with a plurality of ventilation holes and a connecting element according to the invention as described herein. The embodiments and advantages described herein in relation to the connecting element according to the invention also apply correspondingly to the system for fastening the ventilation profile to the substructure.

According to an advantageous embodiment of the neck portion of the connecting portion of the connecting element passes through a ventilation hole of the ventilation profile and the holding portion of the connecting portion engages behind the ventilation profile in the ventilation hole defining area of the ventilation profile. As a result, a secure mounting of the ventilation profile is created parallel to the longitudinal direction of the neck portion of the connecting element and at the same time achieves a free displaceability of the profile element in the longitudinal direction of the ventilation hole. The ventilation profile may comprise a plurality of elongated ventilation holes in a manner known per se, which are oriented in particular parallel to the longitudinal direction of the ventilation profile. In this case, by the system according to the invention by a Thermal expansion of the ventilation profile or the substructure caused warping or distortion of the ventilation profile and the substructure are particularly effectively prevented.

The maximum width of the neck portion of the connecting portion measured in a width direction of the connecting member perpendicular to the longitudinal direction of the neck portion may be less than or approximately equal to the width of the vent hole. The width measured in the same direction of the holding portion of the connecting portion may be greater than the width of the vent hole and less than or equal to the length of the vent hole, so that the holding portion along the width direction of the connecting element through the vent hole can be pushed through and 90 in contrast to the Degree about the longitudinal axis of the neck portion of the connecting element rotated orientation, the ventilation profile engages behind in the region of the ventilation hole.

The system described above may simultaneously constitute a system according to the invention as described herein for attaching a ventilation profile for ventilated facades of a building to a building section. For this purpose, the system may additionally have a fastening profile according to the invention as described herein for fastening the ventilation profile to a building section. The embodiments and advantages described herein in relation to the system according to the invention for fastening a ventilation profile to a building section or with respect to the fastening profile according to the invention apply correspondingly.

Furthermore, the fastening profile comprises 10 a connecting leg 16 for connection to the ventilation profile, which is substantially perpendicular to the mounting leg 12 is oriented. The fastening profile 10 is formed of a flat material and the fastening and the connecting leg 12 . 16 are essentially just trained.

The connecting leg 16 of the fastening profile 10 has a plurality of spaced apart in the longitudinal direction x coupling portions 18 on, in which the connecting leg 16 each can be coupled via a connecting means with the ventilation profile. In each coupling section 18 is a slot 20 of the connecting leg 16 formed, which is oriented with respect to its longitudinal extent perpendicular to the longitudinal direction x. Every slot 20 defines any number of along the longitudinal extent of the slot continuously successive coupling positions in which the connecting leg 16 each can be coupled with a connection means for the ventilation profile. In 1 are only the through the longitudinal ends of a slot 20 defined outermost coupling positions by the reference numeral 22 specially marked.

These are the ventilation holes 32 two in the transverse direction y of the ventilation profile 24 adjacent rows arranged 30 arranged offset in the longitudinal direction x, resulting in a brick pattern-like arrangement of the ventilation holes 32 results.

For connecting the ventilation profile 24 with the fastening profile 10 becomes the horizontal thigh 26 the ventilation profile 24 as in 2 shown on the connecting leg 16 of the fastening profile 10 flat brought to the plant, so that the connecting leg 16 and the horizontal thigh 26 are arranged substantially plane-parallel.

The relative position of ventilation profile 24 and fastening profile 10 with respect to the transverse direction y can be adapted so that it to the width of the ventilation gap to be covered and in particular also to a possible variation of this width over the length of the ventilation gap away, z. B. due to a wall unevenness or the like adapted.

The ventilation profile 24 Namely comes in each relative position so on the mounting profile 10 to plant that at least one ventilation hole 32 with a long hole 20 of the coupling section 18 Aligns and thus with this slot 20 an opening for the passage of the connecting means 34 forms. It is thus avoided, for example, that in a slot 20 available coupling positions 22 completely from between two adjacent ventilation holes 30 the ventilation profile 24 arranged area of the ventilation profile 24 be covered. This will in a simple way a continuous adjustment of the width of the ventilation profile 24 Covered ventilation gap allows.

Then the horizontal leg 26 the ventilation profile 24 flat to the connecting leg 16 of the fastening profile 10 created and the relative position of ventilation profile 24 and fastening profile 10 adjusted so that the ventilation profile 24 the width of the desired ventilation gap 65 exactly covers everywhere. Then attachment profile 10 and ventilation profile 24 over the connecting means 34 connected with each other.

The connecting element 36 will then be like in 6 shown aligned so that the width direction y '(see 5a -C) of the connecting element 36 substantially parallel to the longitudinal direction x of the ventilation profile 24 runs. In this orientation, the connecting element 36 to a for attachment of the connecting element 36 provided surface 66 the substructure 64 stopped. Then, the lower connecting portion 46 of the connecting element 36 in the z-direction through a ventilation hole 32 the ventilation profile 24 stuck through, what with the given parallel orientation of ventilation hole 32 and holding section 50 unhindered is possible.

Subsequently, the connecting element is around the in the ventilation hole 32 arranged neck portion 48 around in the direction of the 6 illustrated arrows 68 turned 90 degrees until it's in 7 shown position occupies. In this position, the holding section engages behind 50 of the lower connecting portion 46 the ventilation profile 24 on both sides of the ventilation hole 32 and thus causes a reliable mounting of the ventilation profile 24 on the connecting element 36 , At the same time, the ventilation profile can 24 opposite the connecting element 36 move in the longitudinal direction x, creating a tension of ventilation profile 24 and substructure 64 is avoided. Due to the vertical offset d ₃ (see 5c ) between the two longitudinal sections 59 (please refer 5c ) of the connecting element 36 arrives at this rotation, the upper mounting portion 42 automatically on the surface 66 the substructure 64 to the plant and can there via appropriate fasteners 37 (please refer 7 ) are attached. This is the ventilation profile 24 stable and stress-free at the building section 62 and on the substructure 64 attached. The facade 61 is then about the ventilation profile 24 through the in 6 and 7 as an arrow 72 indicated ventilation flow ventilated.
