Description

The invention relates to an adapter for holding facade elements (cladding) on the wall or ceiling of a building.

For the attachment of facade elements to the wall or ceiling of buildings, elongated supports or support profiles are used, which are attached to the outer or inner wall, or to the ceiling or soffit of the building, usually via a wall support or the like, and the facade elements (cladding ) Give a hold. The support profiles usually extend vertically over the entire height of the building. Insulation panels or a similar thermal insulation can be provided between the outer wall of the building and the facade elements, as a result of which the wall supports for fixing the support profiles have to overcome greater distances.

In order to connect the facade elements selectively with the vertically extending support profiles, adapters are known. These adapters are connected to the support profiles at certain points. During the assembly of the facade, the facade elements, mostly in the form of facade panels or facade cassettes, are attached to the adapters, for example suspended, plugged in or screwed on.

In practice, however, the problem arises with known adapters, inter alia, that both the facade panels and the support profiles provide different fastening mechanisms, and thus different adapters are required depending on the facade system and support profile system.

These and other problems are solved according to the invention by an adapter according to claim 1 and by a substructure with such an adapter and by a facade cladding with such a substructure.

An adapter according to the invention is designed to hold facade elements on the inner or outer wall or the ceiling or soffit of a building. The adapter according to the invention has a U-shaped cross section with a base limb and two holding limbs arranged or protruding substantially at right angles thereto. On the base leg, two fastening elements are preferably provided for the force-fit and / or form-fit fastening of a support profile arranged on the building and preferably elongated. When mounting on the support profile, the adapter can be adjusted along the support profile in order to achieve an optimal arrangement of the facade element.

For this purpose, a third fastening element can be provided on the base leg, preferably a fixing screw, which is used to fix the base leg and thus the adapter on the support profile. After the adapter has been attached to the support profile using the fastening elements, the adapter is adjusted on the support profile and then fixed using the fixing screw. This third fastening element can be arranged displaceably in a linear guide of the base leg; But it can also be fixed, i.e. not movable. The adapter can also be fixed to the support profile by self-tapping screws.

According to the invention, the two retaining legs each have a preferably U-shaped recess for receiving retaining bolts of a facade element. This can be a U-shaped cutout or a semicircular cutout of the retaining legs, which is suitable for receiving a retaining bolt of the facade element in a form-fitting manner.

In addition, according to the invention, a support bolt is provided between the holding legs of the adapter for the optional form-fitting reception of holding grooves or semicircular or U-shaped cutouts of a facade element. The support bolt is preferably made of aluminum, steel or stainless steel in a solid or hollow design. The recesses and the support bolt can preferably each be arranged in the frontal area of the holding legs. It is thereby achieved that the adapter can be used both for facade elements which comprise a retaining bolt and for facade elements which only have recesses for receiving a retaining bolt on the adapter side. As a result, the adapter can be used universally for various facade systems.

According to the invention, the fastening elements of the adapter are designed as essentially T-shaped material webs. These material webs are preferably arranged on the rear side of the base leg and protrude from the base leg surface in such a way that they allow a T-shaped support profile to be positively received on their sides facing one another and also allow positive insertion into a C- on their sides facing away from one another. allow shaped support profile. The material webs thus form on the one hand an internal C-shaped groove for receiving a T-shaped support profile, as well as outwardly facing webs for form-fitting introduction into a C-shaped support profile surrounding the base leg. This makes the adapter even more universally usable, since it can be used for a wide variety of designs of the support profile.

At least the base leg and the two retaining legs, preferably the entire adapter, can be formed in one piece and particularly preferably made of aluminum, steel or stainless steel. In particular, the material webs are preferably formed in one piece with the base leg. The entire adapter can also be coated in color, preferably in black but also in other colors.

The support bolt can be detachably connected to the retaining legs. This means that the adapter can also be delivered without the support bolt. For example, the support bolt can be inserted into the retaining leg or screwed onto the retaining leg.

The support bolt can be made of aluminum, steel or stainless steel or comprise this material. The support bolt can also be sheathed with plastic, preferably made of elastomers or thermoplastics.

The invention also relates to a substructure for holding facade elements, comprising an adapter according to the invention and a support profile for fastening to the wall or ceiling of a building.

According to the invention it can be provided that the support profile is essentially T-shaped and comprises a support leg via which the support profile is positively and / or non-positively connected to the fastening elements, preferably pushed into them. Such a support profile can thus be introduced with its support leg into a C-shaped groove formed by the material webs of the adapter in a form-fitting manner.

Alternatively, it can be provided that the support profile is essentially C-shaped and has internal grooves, via which the support profile is non-positively and / or positively connected to the fastening elements, preferably the material webs, the material webs of the adapter preferably being inserted into the grooves of the support profile are. This results in a large number of different possible uses for the adapter according to the invention for a wide variety of designs of the support profile.

The invention further comprises a facade cladding comprising a substructure according to the invention and at least one facade element which has suitable means for engaging the adapter. The facade element can be a facade cassette or some other facade cladding.

The facade element can have at least one retaining bolt, which is hooked into one of the recesses of the retaining leg to hold the facade element on the adapter. When assembling the facade element, its retaining bolt is hooked into the recesses of the retaining leg.

It can be provided that the facade element comprises a plurality of retaining bolts, which are hooked into the retaining legs of a plurality of adapters. In this embodiment, the support bolt is not absolutely necessary, so that the adapter can also be used without the support bolt. The support bolt can be removed on site or it cannot be delivered with the adapter at all.

The retaining bolt of the facade element is preferably designed in such a way that it is not visible from the outside. For example, the retaining bolt of the facade element can be arranged behind a protruding area of the side wall of the facade element.

Furthermore, the invention also comprises a facade cladding with a substructure according to the invention and at least one facade element which has at least one preferably U-shaped recess which is hung on the support bolt to hold the facade element on the adapter. In this embodiment, the facade element does not have a retaining bolt, but a recess which can be U-shaped, semicircular or the like, and which is designed for preferably positive engagement in the support bolt of the adapter. Again, it can be provided that the facade element has several recesses that can be inserted into the support bolts of several adapters. The support bolt of the adapter is therefore absolutely necessary in this embodiment.

After the facade element has been connected to the holding legs of the adapter, that is to say has preferably been suspended, it can be fixed to the support profile in a conventional manner, for example by means of fixing screws or the like.

Further features according to the invention emerge from the claims, the description of the exemplary embodiments and the drawings.
