The subject matter of the invention is mounting means for mounting natural stone elements and a respective method. It relates especially to façade engineering and respective natural stone claddings.
Natural stone claddings are increasingly used which in addition to a special visual appeal also ensure a permanent and clean solution. The current trends go in the direction of smaller natural stone elements 11.1, 11.2, 11.3 which are arranged in the manner of belts, as is shown in
Frequently, natural stone elements are mounted on a wall with so-called anchors. One hole needs to be drilled into the wall for each anchor, and each anchor needs to be fastened individually in these holes. The natural stone elements then typically have holes on the rear side which enable placing the natural stone elements on the anchors.
Other façade solutions work with glued natural stone elements. This kind of façade cladding is partly rejected because builders doubt the durability of such glued solutions under changing weather conditions.
It is therefore the object to develop a mounting apparatus or respective mounting means which are easier to handle and which, depending on the wishes of the builder or architect, allow offering elegant and durable claddings with natural stone elements.
It is a further object in accordance with the invention to offer a solution which is stable and durable, with the mounting of the natural stone elements being simpler than was the case with previous approaches.
In accordance with the invention, a mounting means is provided with features shown in claim 1. Moreover, a natural stone cladding is provided with features shown in claim 6 and a method whose details are shown in claim 10. Preferred embodiments are disclosed in the respective dependent claims.
Further details and advantages of the invention will be described below by reference to embodiments and the drawings. Unless reference is made explicitly to a special drawing in the description below, the described features refer to all embodiments, wherein:
It is indicated in
The general arrangement of the novel natural stone cladding 10 in accordance with the invention will be described below. The arrangement is described by reference to a vertical wall surface. The natural stone cladding 10 in accordance with the invention can also be used on other surfaces, as indicated in
The natural stone cladding 10 comprises a plurality of strips (wall-mounting racks) 18 which are mounted parallel to a wall 40 to be lined.
A supporting mount 30 can be fastened at the desired height to such a wall-mounting rack 18.
The counterholder 20 comprises an insertion area 24 which is arranged in a complementary manner to the accommodating area 36 or the placement area that during mounting the insertion area 24 can be slid onto the accommodating area 36 of the supporting mount 30. As a result, the counterholder 20 sits or is disposed in the mounted state on the supporting mount 30, as is shown in
The counterholder 20 comprises a second projection 22 which is arranged to fix the natural stone element 11 on the rear side in the mounted state, as is shown in
Each natural stone element 11 comprises a visible front side 13 and a rear side 16 with a first mechanically produced longitudinal recess 14 (which is also designated here as a horizontal recess) and a second mechanically produced longitudinal recess 15 (which is also designated here as a horizontal recess).
Natural stone elements 11 which are processed in this manner do not yet exist. A special machine tool is used for its production/machining which produces or machines the longitudinal recesses 14 and 15 by circular saw blades which are adjusted in different ways. The first mechanically produced longitudinal recess 14 is preferably produced by a circular saw blade which has a thickness SD, as is shown in
Notice must be taken at this point that the length LA of the natural stone elements can vary.
A further circular saw blade dips with another inclined position from behind into the natural stone element 11 in order to produce a surface 15.1 of the second longitudinal recess 15. The second surface 15.2 of the longitudinal recess 15 is produced by a circular saw blade which lies parallel to the main plane of the natural stone element 11.
Details of the first counterholder 20 are shown in
It is schematically indicated in
In a preferred embodiment which is indicated in
In an especially preferred embodiment of the invention, two securing elements 51.1 and 51.2 are used for each natural stone element 11, which securing elements have differently large spring forces. The securing element 51.1 can have a larger spring force for example in order to tightly clamp the natural stone element 11 with the supporting mount 30.1 and the counterholder 20.1 at a predetermined position. The securing element 50.2 on the other hand has a slightly lower spring force, so that the natural stone element 11 can slightly slip in the region of the supporting mount 30.2 and the counterholder 20.2. Fluctuations caused by temperature can be compensated with this kind of embodiment.
A similar effect can be achieved in that identical securing elements 51 are used at all points, with those surfaces of a pair consisting of supporting mount 30.1 and counterholder 20.1 being coated with a rough material (e.g. sand or corundum) offering good grip which come into contact with the natural stone element 11. The respective surfaces of the other pair are not coated. It is also possible to provide the respective surfaces with a sliding coating, whereas the surfaces of the other remain uncoated. These two approaches can also be combined.
In order to enable good contact on the wall-mounting rack 18, the supporting mount 30 preferably has a planar rear side 31.
Preferably, the supporting mount 30 comprises a nose 34 with a stop face, on which the natural stone element 11 can rest with its rear side 16. This nose 34 is optional. A respective supporting mount 30 is shown in
Both the supporting mount 30 and also the counterholder 20 are preferably made of respectively shaped metal or plastic sections which are cut to size in the respective lengths. These counterholders 20, 30 can thus be produced in a simple and precise way in large piece numbers. Aluminum sections or sections made of nickel-plated or hot-dip galvanized steel have proven to be particularly useful.
Preferably, each pair consisting of a supporting mount 30 and a counterholder 20 together with the applied or inserted securing element 51 has a total height HV1 which is slightly smaller than the height HV2 of the natural stone element 11 (see
An exemplary mounting process will be explained below. The wall-mounting brackets 18.1, 18.2 are mounted at a defined distance HA parallel with respect to each other on a wall 40 or surface to be lined (it is also possible to line other surfaces such as horizontal or oblique surfaces in this manner), as indicated in
At least two support holders 30 and two counterholders 20 are required for each natural stone element 11. In the case of very long natural stone elements 11, it is also possible to use several such pairs. It needs to be ensured however that tensions do not occur in the stone 11.
Depending on statutory regulations, the natural stone elements 11 must be secured in such a way that they cannot break up and then fall down. In order to ensure this, respective means can be provided on the rear side 16. It is either possible to insert or glue a steel cable into a further (e.g. horizontally extending) third recess or the rear side 16 can be covered with a net or band.
A weatherproof rubber ring can also be used as securing element 51 which encompasses the supporting mount 30 and counterholder 20.
