Description

The invention relates to a device for at least liquid-repellent connection of two oppositely positionable profile elements of a building area cover with a base body for supporting the profile elements and with at least one base-side sealing means for sealingly abutment of the body to the profile elements.

On the other hand, the invention relates to an arrangement of profile elements of a building area cover and a device for at least liquid-repellent connection to a butt joint of the profile elements, wherein between at least one of the profile elements and a base body of the device at least one base-side sealing device is arranged acting.

Moreover, the invention relates to a method for producing a universal joint connector for at least liquid-repellent connecting two opposing profile elements on a butt joint on a cover assembly for a building part area in which the profile elements are supported in the region of the butt joint with a main body of the universal joint connector.

Generic devices for at least liquid-repellent connection of two oppositely positionable profile elements of a building area cover exist in general as a butt connector in the prior art in various forms. For example, they comprise a corrugated profiled base body for supporting two abutting edge side opposite profiled sheets for covering a cornice, a wall or other building area. Due to the corrugated profiled structure, the risk, in particular of a critical rainwater intrusion into protected building areas below the respective protective cover can be reduced. However, such provided with corrugated profiled bodies shock connectors have moreover no additional sealing means by which they can seal against the underlying profile elements.

In addition, there are other joint connectors, which have a rubberized sealing device. In this case, the respective rubberized sealing device is often merely glued to a base body of the butt connector, which, however, due to insufficient adhesive adhesion, quickly entails the risk that the rubberized sealing device will detach at least in regions from the base body during mounting. In such a case, it may be that the rubberized sealing device can already ensure shortly after assembly no or only reduced sealing properties.

Alternatively, sealing devices of generic butt connectors can be clamped into an adhesive connection cumulatively or alternatively into corresponding brackets. However, in practice it has also been shown here that these often easily come out of the holder.

It is an object of the present invention to further develop generic butt connectors so that increased functional reliability is ensured.

The object of the invention is achieved on the one hand by a device for at least liquid-repellent connection of two oppositely positionable profile elements of a building area cover with a base body for supporting the profile elements and with at least one base-side sealing means for sealingly abutment of the base body on the profile elements, wherein the device is characterized thereby, the at least one base-body-side sealing device is arranged directly vulcanized on the surface of the base body.

The direct vulcanization of the base-body-side sealing device on the body, a particularly intimate connection between the base-side sealing device and the actual body of the present device are generated so that the risk of unintentional and too easy detachment of the body-side sealing device is significantly reduced, if not even in terms most operating conditions is almost completely excluded.

Thus, in particular there is a high level of operational reliability with regard to expansion movements on a building area coverage due to weather conditions, such as sunshine, rain, frost, etc. Here, it can easily come to the building area covers temperature amplitudes between 60 ° C to 80 ° C, for example when on direct sunlight Rain follows. The associated expansion movements can also burden the connection between the sealing devices and the base body, so that sooner or later fails. However, this danger is extremely reduced by the vulcanization.

The term "device for at least liquid-repellent connection of two opposing positionable profile elements of a building area coverage" describes in the sense of the present invention, any device which can be substructured with regard to the building area cover, by means of which a generic butt joint can be provided. In this respect, the present terms device for at least liquid-repellent compound and universal butt connector in the context of the invention are used synonymously.

The scope of the device according to the invention extends to the liquid-proof connection of wall, roof edge, cornice, ridge, and window sill covers or the like for all common Baumetalldünnbleche.

The at least liquid-repellent properties relate primarily to influences of rainwater or spray water.

A particularly preferred embodiment provides that the at least one base-body-side sealing device comprises a sealing body which can be adjusted at the time of placing on the base body by at least one of the parameters time, pressure, temperature and / or an activator. Such a directly vulcanized sealing device is particularly weather-resistant, in particular with regard to premature detachment from a substrate. In this respect, in the present case, an exceptionally good rubber-metal compound can be produced.

In addition, an exceptionally preferred embodiment provides that the at least one base-side sealing device comprises a rubber material which can be adjusted with regard to its degree of crosslinking as a function of at least the time, the pressure, the temperature and / or an activator. As a result, in particular, hardness properties of the at least one base-body-side sealing device can be adapted individually to existing installation requirements without having to hold a correspondingly large number of sealing devices. Preferably, the selected rubber is black.

In this respect, the object of the invention is also achieved by a method for producing a universal joint connector for at least liquid-repellent bonding two oppositely positionable profile elements on a butt joint of a cover assembly for a building section, in which the profile elements in the area of the butt joint with a base body of the universal joint connector can be, wherein the method is characterized in that on the base body of the universal joint connector at least one sealing device is vulcanized.

The process of vulcanization creates a particularly intimate connection between the at least one sealing device and the main body.

A preferred variant of the method provides that the physical properties of the at least one sealing device are at least partially adjusted even when the at least one sealing device is applied to the base body. For example, this can still be done taking into account the time, the pressure and the temperature, with an influence on the physical properties need not be limited to this.

The application can be carried out with the aid of an extrusion process. Preferably, a rolled-rubber strip of material and the base body are inserted into a press tool, so that subsequently the sealing device is formed and vulcanized immediately on the base body. As a result, a particularly good rubber-metal compound can be produced. The rubber-material strip may advantageously be delivered as a rolled-up raw rubber strip.

It is understood that a related body-side sealing device can be made in a variety of forms.

It is advantageous if the at least one base-side sealing device comprises at least two spaced-apart sealing lip elements. By means of the two spaced-apart sealing lip elements, the security against the ingress of particular rainwater can be increased again.

Moreover, it is advantageous if a distance between two spaced-apart arranged on the base body side sealing means and / or between two mutually spaced sealing lip elements of a base-side sealing device is selected depending on a width of the main body of the device.

The operational safety of the present device can be further increased if the at least one profile-side sealing device comprises a sealing lip unit designed in the shape of a U. Such a U-shaped sealing lip unit on the one hand structurally and thus particularly easily two spaced sealing lip elements can be provided. On the other hand, this can provide a substantially larger vulcanizable surface on the present sealing device, so that the connection between the base body and the directly vulcanized sealing device can be further increased advantageously.

Furthermore, it is advantageous if the at least one base-side sealing device comprises at least one sealing lip element, which has a sealing lip web with a height starting from the main body of more than 5 mm and less than 15 mm, preferably 8 mm.

The present device can be particularly easily adapted to structural conditions, for example, with respect to a width of a wall to be covered or the like, when the at least one base-side sealing device is bendable together with the main body.

Advantageously, in the present case, the danger is almost ruled out that the body-side sealing device separates from the body especially in the region of a bending edge, since the adhesion forces are more than sufficiently high in terms of Vulkanisationsverbindung invention between the base body sealing device and the body, so that unintentional detachment of the body side Sealing device of the main body can be almost completely excluded.

In this respect, it is advantageous if adhesion forces act between the base body and the at least one base-side sealing device which are greater than adhesive bonding adhesion forces, as is the case with conventional butt joints with glued sealing devices.

It is understood that the adhesion forces can additionally be advantageously influenced, in particular also reinforced, by a chemical and / or mechanical surface treatment of the basic body. For example, the base body is coated before vulcanization with a suitable bonding agent.

Furthermore, it is advantageous if the base body has a thickness of more than 0.5 mm and less than 2 mm, since it is sufficiently stable in terms of such a strength in terms of externally applied loads and on the other still sufficiently flexible and thus is also capable of bending, in order to be able to be adapted on site to corresponding structural conditions without any problems.

It is understood that the base body can also be made of a variety of materials. The materials aluminum or stainless steel have proven to be particularly suitable, since a particularly high degree of universality can be achieved with these materials. In this respect, not many different materials need to be kept. Aluminum is cheaper than stainless steel, relatively insensitive, silver-colored, like many other building materials also, light and easy to work with and can be easily combined with almost all metals except copper. Stainless steel, however, is more expensive, but also higher quality and can be combined well with copper. In addition, especially stainless steel is particularly insensitive to the weather.

The present device can also be further developed particularly advantageous if the main body is made of a more than 1 m, preferably more than 1.5 m, long strip material. Often, a length of 3 m long strip material proves to be advantageous, since this also a greater application flexibility can be achieved.

In addition, the object of the invention is also achieved by an arrangement of profile elements of a building area cover and a device for at least liquid-repellent connection to a butt joint of the profile elements, wherein between at least one of the profile elements and a base body of the device at least one base-side sealing device is arranged acting the arrangement is characterized in that the at least one base-side sealing device on the one hand directly vulcanized on the base body and on the other hand is arranged adjacent to the at least one of the profile elements.

By means of the present arrangement can be achieved in a structurally particularly simple manner a hugely durable and reliable liquid-tight seal between a butt connector and a building area coverage.

In particular, it is advantageous if the arrangement comprises a device according to at least one of the features explained here.

It should be mentioned at this point that it is advantageous if a metal strip is arranged between two spaced-apart base-body-side sealing devices, whereby even larger joints between the individual profile elements can be bridged optically and structurally particularly advantageous.

In addition, the present device can be installed easily and quickly. A soldering, folding or other sealing measures and expansion compensators are superfluous and an open Butt joint allows free movement of the cover profile.

Further advantages, objects and features of the present invention will be elucidated with reference to the appended drawing and the following description in which, by way of example, a universal butt connector with a main body and sealing devices vulcanized thereon is shown and described.

In the drawing show:

1 schematically shows a perspective view of a universal joint connector having a vulcanized seal means having body on a building wall for underfounding a building cover;

2 schematically a head-side view of the universal connector from the 1 ;

3 schematically a perspective view of the universal joint connector of the 1 and 2 with a first profile element of the building wall covering placed thereon; and

4 schematically another perspective view of the universal joint connector from the 1 to 3 with a second profile element of the building wall covering placed thereon.

The in the 1 to 4 shown device 1 for at least liquid-repellent connection of two oppositely positioned profile elements 2 and 3 (see in particular 4 ) has a main body 4 for supporting the profile elements 2 and 3 on.

For at least liquid-repellent bonding of the two profile elements 2 and 3 are two body-side sealing devices 5 and 6 directly on the surface 7 of the basic body 4 vulcanized, creating a particularly intimate connection between the body-side sealing devices 5 and 6 and the body 4 is realized.

Advantageously, the two body-side sealing devices 5 and 6 with regard to their physical properties even during the vulcanization process by influencing about time, pressure and temperature parameters individually adjustable, which also provides particularly advantageous connection properties between the body-side sealing devices 5 and 6 and the body 4 can be created.

In this respect, the present device provides 1 a particularly reliable universal butt connector 8th also for rainproof connection of two opposing profile elements 2 and 3 at a butt joint 9 (please refer 4 ) a cover assembly 10 for a part of the building 11 where the building part area 11 in this embodiment, a building wall 12 which is through the cover assembly 10 especially to be protected from rainwater.

To the main body 4 permanently on the building wall 12 To install, this is by means of a variety of suitable screws 13 (here only exemplified) or nails on the building wall 12 bolted resting.

The two body-side sealing devices 5 and 6 extend in the longitudinal direction 14 of the basic body 7 from a first side of the head 15 up to a second side of the head 16 of the basic body 4 , the two sides of the head 15 and 16 depending on the building wall width 17 previously correspondingly together with the body-side sealing devices 5 and 6 was folded.

This bending is not a problem in this case, since the two body-side sealing devices 5 and 6 directly on the surface 7 are arranged vulcanized, so that the body-side sealing devices 5 and 6 despite the chipping of the main body 4 by about 90 ° even at the respective bending edge 18 respectively. 19 also not permanently from the main body 4 peel off. Thus, a particularly reliable seal is especially against rainwater between the body 4 and the two profile elements 2 and 3 ensured.

How well the presentation according to the 2 can be removed, each of the body-side sealing means 5 respectively. 6 a U-shaped sealing lip unit 20 on, the structure of the sake of clarity, only with respect to the base-side sealing device 6 is explained in more detail. The body-side sealing device 5 However, this is identical.

The body-side sealing device 6 has two spaced sealing lip elements 25 and 26 on which over a floor element 27 the body-side sealing device 6 connected to each other.

Each of the two sealing lip elements 25 and 26 has a sealing lip web 28 (here only exemplified) with a height 29 of 8 mm.

A distance 30 between the two sealing lip elements 25 and 26 is 25 mm in this embodiment, whereas a seal distance 31 between the two body-side sealing devices 5 and 6 this is 45 mm.

The width 32 of the basic body 4 is 150 mm, with the sealing lip element spacing 30 and / or the sealant clearance 31 depending on the width 32 of the basic body 4 is advantageous selectable.

The material of the basic body 4 here consists of a 0.8 mm thick stainless steel sheet, while the two sealing devices 5 and 6 are made of an elastomeric rubber black.

The basic length (not shown here, since the main body 4 already shown cut to length) of the present body 4 amounts to 3 m, so the main body 4 together with the vulcanised body-side sealing devices 5 and 6 according to the building wall width 17 cut to length and shown folded.

By means of the present device 1 or universal connector 8th can a particular rainwater-resistant connection in the butt joint 9 on the cover assembly 10 be ensured because the sealing lip elements 25 and 26 on both sides when hanging the two profile elements 2 and 3 cling to these and thus ensure a secure barrier against the ingress of rainwater in particular. In this respect, this creates a particularly high-quality building area coverage.

The butt joint 9 can easily be 5 to 10 mm or less or more, so that a free movement of the two profile elements 2 and 3 when implementing the cover assembly 10 is possible.

Pass the two profile elements 2 and 3 from a colored aluminum, a pre-weathered zinc or copper, may be in the middle of the device 1 or in the butt joint area 9 the cover assembly 10 easily about 40 mm narrow, to the profile elements 2 and 3 color matching metal strips are inserted, the previously according to the specifications of the body 4 must be folded.
