Definitions

  • the invention relates to a natural stone slab according to the preamble of claim 1.
  • Natural stone slabs are often used, in particular for the cladding of the outer facades of large buildings, and must be fastened to the facade by means of suitable fastening devices.
  • the type of fastener receives increased attention because large-format natural stone slabs have a considerable weight and the detachment of a natural stone slab from the facade structure not only leads to the destruction of the natural stone slab but is also associated with a considerable risk to people and property.
  • the natural stone slabs are usually attached to the structure by means of mounting elements in the form of tab-like fastening elements.
  • these brackets are connected in a suitable manner to the load-bearing structure of the building, on the other hand, they hold the natural stone slabs at their edges in the selected position.
  • the tabs engage in the recesses provided on the plate edge.
  • Pronounced solid natural stone such as marble
  • weight-saving solutions are proposed by using natural stone slabs with reduced wall thickness and thin-walled, light-weight supporting slabs made of other materials, such as aluminum, plastic and the like. Like. Be put together. Although this combination leads to a noticeable reduction in weight, it makes the manufacture of such facade cladding difficult. From format sizes of more than 1 sqm, there is also a detachment of the natural stone slab connected to the aluminum or plastic support plate as well as breaks in the natural stone slab. This is largely due to the fact that the support plate expands more when heated than the natural stone plate. The service life of such composite panels is therefore limited.
  • the mechanical fastening means explained at the outset are predominantly used for the facade cladding.
  • the edge-side mounting of these mechanical fasteners can lead to breakouts and damage to the plate edges under dynamic loads as a result of wind, but also to breaks of the plates themselves.
  • the natural stone slabs are mostly used with excessive thickness, which however results in an increased weight and so on with correspondingly dimensioned fasteners required.
  • the mechanical fastening elements frequently engage in recesses in the edge region of the natural stone slab and the plate is thus weakened, particularly in the areas at risk, a reduction in the plate thickness of natural stone slabs is limited when using mechanical fastening elements.
  • the object of the invention is to ensure a stable and secure attachment of large-format natural stone slabs.
  • holding elements are arranged on the back of the natural stone slab, which are connected to the natural stone slab by means of a glass solder. Furthermore, the holding means are arranged on the plate at attachment points determined according to static requirements.
  • the advantage of this fastening system is that the natural stone slab remains completely unaffected by the fastener itself, in particular no weakening of the plate edge areas by recesses is necessary for the insertion of fasteners. Nevertheless, an intimate bond is achieved through the glass solder.
  • the glass solder melting during the burning process dissolves the surfaces of the mounting element and the natural stone plate in the fastening area somewhat, so that after cooling, there is a toothing between the elements mounting element / glass solder and natural stone plate.
  • the mounting elements can be made of the same or similar material as the plate and serve as such to fasten the plate directly or to receive a metal fastener. In the latter case, you are completely free to choose the material for the fasteners. Ceramic material has proven to be particularly suitable as the material for the mounting elements.
  • the holding elements can be provided with recesses or bores for receiving metallic fastening means, which considerably facilitates the rotation of the plate according to the invention designed in this way on a framework or the like, for example.
  • the fasteners can already before Fire may be used in the mounting elements. A central load transfer is reliably achieved due to the interlocking between the mounting element and the metallic fastening means.
  • the firing can also take place without such metallic fastening means if the recess or bore in the holding element is designed in such a way that it is possible to subsequently insert metallic fastening means into the holding elements.
  • Such fasteners can then be, for example, expansion dowels, insertion pins, spacers or the like.
  • the invention thus creates a plate which can be fastened directly to walls, ceilings, mounting frames or the like and in which the attachment points can be freely selected from a static point of view.
  • the plate and the holding element are made of the same material, so that a homogeneous part with the same coefficient of thermal expansion and the same strength properties is produced in the area of the fastening of the holding elements. Even if the fastener is made of metal, this does not change the formation of a homogeneous body from the plate and the holding element.
  • both the mounting element or the fastening means and the natural stone plate remain completely unchanged.
  • the mounting elements or fasteners are not located on the edge, but in the parts on the side of the plate facing away from the visible side, which provide the best structural options for fastening.
  • the edge areas remain completely unaffected by the bracket, so that the disadvantages associated with an edge fastening for the natural stone slab are basically avoided.
  • this is the transition from a two-point storage, as is the case with the edge fastening, allows for a multi-point storage.
  • the size and shape of the base of the mounting element can be chosen so that the stress peaks that occur in the bearing points do not exceed the stresses in the middle of the field, ie in the middle of the field bounded by the fastening points. This enables a noticeable reduction in the thickness of the natural stone slab.
  • This fracture safety coating has to cover at least the entire length dimension of partial areas of a plate so that in the event of damage the plate parts cannot be released from their assembly and fall to the ground.
  • the coating also cover the area of the holding elements and to cover them, after which the glass solder connection is also protected against a possible atmospheric acid attack.
  • This shatterproof coating preferably consists of a mineral, preferably glass fiber fabric or nonwoven, which is impregnated with an epoxy resin.
  • the mounting elements are expedient not to design the mounting elements as a sharp-edged cuboid or cylinder, but rather in a dome shape in a further embodiment of the invention.
  • Another solution to this problem is to ensure that acid rain or moisture can immediately drain from the area of the ceramic bond. This is preferably done with the help of channel-like recesses which extend from the edge of the holding element in the part which is intended to receive the metallic fastening means in at least one direction, preferably in four mutually perpendicular directions.
  • the present solution achieves weight savings in comparison to edge-mounted fastening options of up to 50% for the weight of the natural stone slab.
  • 1 denotes a large-format natural stone slab, of which only a part is shown.
  • a holding element 2 Arranged on the side opposite the visible side of the natural stone slab 1 is a holding element 2 which, in the exemplary embodiment shown, has a circular plan.
  • the mounting element 2 is intimately connected to the natural stone slab 1 via a glass solder 3.
  • a countersunk screw 5 In a central bore 4 of the mounting element 2, which opens too conically downwards, a countersunk screw 5 is received, which serves as a fastening means and via which the natural stone slab 1 can be fastened to the facade.
  • the back of the natural stone slab is finally provided with a break-resistant coating, which is also drawn at 6 over the holding element 2, so that the connection of the holding element 2 with the natural stone slab 1 is protected in particular against atmospheric acid attack.
  • the support elements 2 are arranged in particular in the edge area of the large-format plate, in particular in the corner region of the plate. Depending on the size of the large-format plate, more than four mounting elements 2 can also be arranged distributed over the circumference of the plate.
  • a depression 7 can be worked into the natural stone slab 1 in the area of the attachment point of the mounting element, which depression serves to receive the glass solder 3.
  • a lead borate glass solder is particularly suitable as a glass solder. Expediently, the glass solder used is a glass which softens at temperatures of about 400 to 450 ° C and is sufficiently flowable (viscosity ⁇ 105 dPa ⁇ s).
  • the attachment of the support elements 2 to the back of the natural stone slab 1 takes place in that a natural stone slab 1 is arranged lying on its visible side and the glass solder 3 is placed on the desired attachment points of the support elements 2 from above.
  • the glass solder 3 can be pressed into a ring shape or can also be used in powder form.
