Description

The invention relates to a holding device for panels for facade cladding, comprising a base body with a rear contact surface for abutment against a substructure, a perpendicular to the contact surface aligned first receiving area for receiving a first panel portion and a parallel to the contact surface aligned second receiving area for receiving a second panel section ,

A holding device for panels for cladding is known as part of the "cassette system K25" the company Rheinzink (Datteln, Germany). Such a system allows a determination of a panel on a substructure, so that the weight of the panel in the substructure derivable and wind-related movement of the panel can be largely avoided. For this purpose, a first receiving area is provided, in which a first, in the fully assembled position of a panel horizontally aligned first panel section is receivable. In this way, the weight of a panel can be derived in the body and from there into the substructure. A second, in the assembled position of a panel vertically aligned receiving area allows the inclusion of a second panel section, which is trapped between the main body and the substructure in the horizontal direction. This allows the determination of a panel in the horizontal direction and prevents wind-induced detachment of the panel from the substructure.

The system described above has several disadvantages. It is not suitable for different panel thicknesses, requires a time-consuming fixation of the panels on the base body by means of rivets and causes noise in temperature fluctuations. In addition, damage caused by contact corrosion can occur.

On this basis, the present invention seeks to provide a holding device with which as many of the aforementioned disadvantages can be avoided.

This object is achieved in a holding device of the type mentioned above in that at least one resiliently deformable insert element is provided for fixing a panel section in at least one of the receiving areas, which can be applied under the action of restoring forces on the panel section and a contact between the panel and the main body prevented.

The holding device according to the invention enables the definition of panels with different thicknesses. This is achieved in that an insert element is provided, which is elastically deformable. By the exercise of restoring forces, it is also possible to dispense with a different attachment (for example, by riveting). Further, the insert member allows a panel portion and the body to be separated from each other so that they are not in contact with each other. Thus, a variably usable, easy to handle and permanently damage-free and low-noise fixation of a panel on a substructure is possible.

The resiliently deformable insert element has the further advantage that a panel section arranged in the respective receiving region does not have to be arranged absolutely parallel to a main extension direction of the receiving region, but can also be arranged inclined relative to the main extension direction. In this way, unevenness of the substructure can be compensated in a particularly simple and easy to install way. This is particularly advantageous in the assembly of bump-sensitive panels with low material thicknesses.

In a preferred embodiment of the holding device, the base body is made of a metallic material, for example aluminum. In this case, it is preferred that the base body is a continuous casting profile.

The insert element is preferably made of a plastic material, in particular of an elastomer. A preferred material is ethylene-propylene-diene rubber (EPDM).

It is conceivable that the insert element comes to rest flat against a panel section. However, it is preferred that the insert element comprises a plurality of bending elastically deformable abutment lips. In this way, the introduction of a panel section into a receiving area is simplified. In addition, the plant lips can rest against a panel section with comparatively high contact forces, so that it can be reliably fixed in the respective receiving area.

It is preferred that the abutment lips, as seen from a base in the direction of the free end of the abutment lips, extend in a lip plane which forms an acute angle together with an insertion plane of a panel section. In this way, the system lips can be pushed laterally when inserting a panel section into a receiving area. At a Running the panel portion from a receiving area, the investment lips act as a barb due to the inclined orientation. For carrying out a panel section from a receiving area, the abutment lips are compressed in one another, whereby a resistance to a panel section being moved out of a receiving area is increased. Thus, a panel portion can be reliably and permanently secured in a receiving area.

It is further preferred if the base body has a third receiving area for receiving a third panel section. This allows a more flexible use of the holding device for different installation situations and panel geometries. Moreover, it is advantageous that the third receiving area makes it possible to create an additional ventilation path in the region of the second receiving area.

It is particularly preferred that the third receiving area is aligned parallel to the second receiving area. This simplifies the assembly of panels whose viewing surfaces are separated in the vertical direction by a joint.

The third receiving area is preferably bounded by two walls of the base body which extend parallel to the rear contact surface. In particular, a front wall remote from the rear contact surface is longer than a rear wall adjacent thereto. This has the advantage that in panels whose viewing surfaces are spaced apart by a joint, the rear portions of the holding device are not visible even at an unfavorable angle.

It is particularly preferred if the insert element extends over a plurality of receiving areas, preferably over all receiving areas. In the simplest case, the holding device is formed from two components, namely from geanu a base body and from exactly one insert element.

In a further advantageous embodiment of the invention, it is provided that the contact surface is formed by a base body portion having an enforcement, in particular in the form of a hole for a fastener for attachment of the body to the substructure, and that adjacent to the contact surface, in the area Enforcement, a space for receiving material chips is provided. This makes it possible to introduce a fastening element, in particular a screw, into the substructure by machining and to pick up the resulting chips in the free space, whereby an otherwise possible detachment or lifting of the base body and its contact surface from the substructure can be avoided.

The free space is preferably groove-shaped and has at least one open groove end, which allows the removal ("falling out") of chips from the free space out. A possible whereabouts of residual chips in the free space is not critical, since it is protected in the assembled state of the holding device from weather and water. A risk of corrosion due to a whereabouts of residual chips in the free space therefore does not exist.

One in the 3 to 7 total with the reference numeral 10 designated holding device comprises a main body 12 (see. 1 ) and an insert element 14 (see. 2 ).

The main body 12 is in particular integrally formed and preferably in the form of a continuous casting of a metallic material. The main body 12 includes a body portion 16 with a rear contact surface 18 for installation against a substructure 20 (see. 3 to 7 ).

From the body section 16 starting from a U-shaped section extends 22 which is perpendicular to the contact surface 18 aligned first receiving area 24 having.

To the U-shaped section 22 close, parallel to the body portion 16 aligned, a front wall 26 and a back wall 28 at.

A back surface 30 the back wall 28 runs parallel to the contact surface 18 and is relative to the contact surface 18 towards the front wall 26 added. This creates parallel and adjacent to the back 30 a second recording area 32 ,

The front wall 26 , the back wall 28 and the U-shaped section 22 together define a third reception area 34 which is parallel to the second receiving area 32 extends.

The course of the boundaries of the recording areas 24 . 32 and 34 is to the outer contour of an insert element 14 customized. The insert element 14 is preferably made of an elastomer, in particular of EPDM. The insert element 14 is preferably formed in one piece.

The insert element 14 has a first element section 36 , a second element section 38 and a third element section 40 on. The element sections 36 to 40 each have an outer contour, the contour of a respective receiving area 24 . 32 . 34 is adjusted.

The element sections 36 and 40 each have walls extending parallel to each other 42 and 44 on that over a connecting wall 46 connected to each other. The second element section 38 has a single wall 48 on, which for connecting the first element section 36 and the third element section 40 serves.

The element sections 36 . 38 and 40 have a plurality of plant lips 50 on, each one between a base 52 and a free end 54 extend. The investment lips 50 are relative to the walls 42 . 44 . 48 in a sloping lip plane 56 aligned. The lip level 56 limited together with an introduction level 58 a panel section at an acute angle 60 , which is preferably between about 20 ° and about 70 °.

The insert element 14 preferably has edge-side attachment portions 62 . 64 on, which for additional determination of the insert element 14 to the body 12 serve. For this purpose, grooves are on the body 66 and / or protrusions 68 provided, which with the attachment sections 62 . 64 of the insert element 14 interact.

For fastening the holding device 10 indicates the basic body 16 an enforcement 70 (see. 3 to 7 ) on. This serves to pass through a fastening element 72 , in particular a screw. To the enforcement 70 adjacent and starting from the contact surface 18 has the body portion 16 a groove-shaped, open-sided free space 73 on. This serves for receiving and discharging material chips when screwing the fastener 72 in the substructure 20 ,

At the substructure 20 it is preferably a vertical wall of a building or a vertically extending wall element.

The holding device 10 becomes so at the substructure 20 mounted that the first receiving area 24 extends in the vertical direction, so that the second receiving area 32 and the third recording area 34 extend in the vertical direction. It is possible that the second recording area 32 and the third recording area 34 are open at the bottom in relation to the direction of gravity (cf. 3 to 6 ) or open at the top (cf. 7 ).

The holding device 10 serves for the attachment of a plurality of panels, for example a top panel in the position of use 74 and a lower in use position panel 76 , It is possible that between the visible surfaces of the panels 74 and 76 a fugue running in a horizontal direction 78 is provided (cf. 3 to 5 ), or that in the area of a transition 80 between two panels 74 . 76 no or only a very small distance is formed. The panels 74 . 76 are made of a sheet having a material thickness of, for example, between about 1 mm and about 4 mm.

The stacked panels 74 . 76 are preferably identical to each other. These panels have a viewing section extending in a vertical direction 82 on.

At the lower in use position end of a panel is a perpendicular to the viewing section 82 extending lower horizontal section 84 and a parallel to the viewing section 82 extending lower end portion 86 intended.

At the upper end of a panel in the position of use is a perpendicular to the viewing section 82 extending upper horizontal section 88 , one parallel to the viewing section 82 extending rearward section 90 and a parallel to the upper horizontal section 88 extending end portion 92 intended.

The sections 82 . 84 and 86 together form a in-use position of a panel 74 . 76 open at the top U. The sections 88 . 90 and 92 form in the position of use of a panel 74 . 76 starting from the substructure 20 forward open U.

For mounting the panels 74 . 76 panels are mounted from bottom to top. A first panel 76 comes with its rear section 90 in contact with the substructure 20 brought. Subsequently, the main body 12 the holding device on the end portion 92 of the panel 76 placed. This is the end section 92 in the first recording area 24 of the basic body 12 introduced. Here are the investment lips 50 bent laterally; These lie down because of the resulting restoring forces against the end section 92 at. When the contact surface 18 of the basic body 12 in contact with the substructure 20 The sealing lips are also used 50 of the second recording area 32 deformed.

For fixing the basic body 12 on the substructure 20 becomes the fastener 72 with the substructure 20 screwed.

Subsequently, another panel 74 with the holding device 10 get connected. For this purpose, the end section 86 of the panel 74 parallel to the end section 90 of the panel 76 in the second recording area 32 inserted. This goes with a stronger deformation of at least a portion of the plant lips 50 of the second recording area 32 associated.

Due to the deformation of the plant lips 50 is also the inclusion of panel sections with different material thickness allows. For example, thin-walled panels 74 . 76 be used (see. 3 ) or thick-walled panels 74 . 76 (see. 4 ). The thicker the panel sections are, the more the plant lips deform 50 , In extreme cases, the investment lips extend 50 after completion of the assembly parallel to the predetermined panel sections, for example to the panel sections 92 . 86 and 90 ,

It is possible that a lower horizontal section 84 and an upper horizontal section 88 a panel 74 . 76 the same depth, ie the same distance from the substructure 20 to the sight section 82 exhibit.

It is also possible that the lower horizontal section 84 compared to the upper horizontal section 88 has a smaller depth, so that the end portion 86 a lower end of a panel, such as a panel 74 , with the third recording area 34 can be added (cf. 5 ). Out 5 It can be seen that even with a direction of view symbolized by means of an arrow 94 through the fugue 78 through the rear portions of the holding device 10 are hidden, which is in particular because that is different from the U-shaped section 22 extending rear wall 28 shorter than the front wall 26 ,

It is also possible that the sections running parallel to the substructure 86 and 90 the panels 74 and 76 starting from the horizontal sections 84 and 88 are each angled downwards. This is in 7 shown.
