Definitions

  • the invention relates to a fastening arrangement for a facade panel with the features of the preamble of claim 1 and a Agraffe with the features of the preamble of claim 7.
  • Such fastening arrangements with an agraff for fastening a facade panel to a substructure are well known.
  • the facade panel is connected to a fastening element with the Agraffe, wherein the Agraffe has a receiving device for receiving the fastener.
  • the agraffe in turn is connected to the substructure.
  • the facade panel of a vertically-horizontally oriented façade surface is suspended by means of the agraffe in a horizontally extending support of the substructure.
  • the Agraffe transmits forces acting parallel and orthogonal to the plane defined by the facade panel in the substructure.
  • the substructure is anchored in a supporting structure, for example the outer wall of a building.
  • Such a fastening arrangement is for example from the document WO 98/49412 known.
  • the publication EP 0 595 062 A1 shows a further fastening arrangement with a hook-shaped Agraffe which is connected via a fastening element, an undercut anchor, with the facade panel.
  • the undercut anchor is attached to the Agraffe in a receiving device, designed as a cylindrical bore receiving opening, with a screw.
  • the Agraffe is hooked with a hook-shaped suspension element in a horizontally extending support of the substructure, which is anchored by means of a dowel directly into a load-bearing wall of a building.
  • the facade panel comprises in this case two plate-shaped discs which are glued together by a thermoplastic film. To prevent slippage of the not held by the fastener front disc in the failure of the bond, is from the document EP 0 552 101 A1 It is known that the front disc is secured against slipping by a retaining clip arranged on the fastening element.
  • a major disadvantage of the known fastening arrangements is that due to thermal stresses, such as temperature changes, constraining forces can arise, which act on the fasteners and the facade panels.
  • the constraining forces arise when the substructure due to temperature changes deforms differently than the facade panel, that is, when the position of the fastener in the facade panel changes relative to the position of the attached to the substructure Agraffe.
  • the clasps are slidably attached to the substructure by hanging, due to the friction between Agraffe and carrier arise but relatively large forces especially in heavy facade panels.
  • the object of the invention is therefore to propose a comparison with the prior art improved mounting arrangement with a Agraffe in which the constraining forces occurring due to thermal stress are minimized.
  • the fastening arrangement according to the invention for a facade panel has a facade panel, a clasp and a fastening element which is connected to the facade panel.
  • the Agraffe serves for fastening the fastening arrangement to a substructure and comprises a receiving device for receiving the fastening element.
  • the receiving device is designed such that only those forces can be transmitted to the Agraffe by the fastener, which act orthogonal to the plane of the facade panel.
  • the "level of the façade panel” corresponds to the level that is defined by the façade itself. In a horizontally-vertically oriented façade, the level of the façade panel is characterized by the height and length of the façade panel. The height and length of the facade panel is usually much larger, often by ten to a hundred times, than the thickness of the facade panel.
  • forces acting orthogonal to the plane are wind forces that may be transmitted through the fastener from the facing panel to the agraffe.
  • the transmission of forces parallel to or in the plane of Facade plate act, can not be transmitted through the fastener on the clasps due to the design of the receiving devices. This applies in particular to forced forces caused by temperature, but also to the weight of the façade panel in the case of vertically-horizontally oriented facades.
  • a preferred embodiment of the fastening arrangement according to the invention has a receiving device, which is designed as a receiving opening, wherein the fastening element is not applied to the lateral surface of the receiving opening.
  • the receiving opening may be a bore in the agraffe, the lateral surface corresponding to the receiving opening of the borehole wall.
  • the diameter of the bore is substantially larger than the outer diameter of the part of the fastener, which lies in the receiving opening.
  • a further preferred embodiment of the fastening arrangement according to the invention provides that a spacer element is arranged in the receiving opening.
  • a connection between the fastener and Agraffe must be created.
  • an undercut anchor is used as the fastening element, which has a threaded bolt or, alternatively, an internal thread
  • the transmission of the forces can be effected by a washer, which is fastened to the undercut anchor with a nut or a screw, which abuts against the agraff, and whose outside diameter is greater as the diameter of the receiving opening.
  • the spacer element is for example a spacer sleeve, which is arranged on the threaded bolt or on the screw of the undercut anchor.
  • the spacer is designed such that the washer is applied after tightening the Agraffe essentially without play, but no friction between the washer and Agraffe can act.
  • the receiving device can continue to act as a sliding bearing even with tight-tension washer, which prevents the emergence of constraining forces due to temperature-induced changes in length of the facade panel or the substructure.
  • the transmission of forces between retaining clip and Agraffe can be done by a positive, frictional or cohesive connection between retaining clip and Agraffe.
  • the retaining clip may be integrally formed on the Agraffe.
  • the retaining clip is for example hook-shaped, with a cantilever, on which rests the facade panel. It is advantageous if the retaining clip is designed such that the friction between the retaining clip and facade panel is minimized. Friction occurs when the pressed by its own weight on the retaining clip facade panel should move relative to Agraffe, as is possible for example in a temperature-induced change in length of the substructure or the facade panel.
  • One way to reduce the friction is, for example, the formation of an intermediate layer of plastic, which forms a kind of sliding bearing for the facade panel on the retaining clip.
  • the retaining clip is particularly advantageous if the facade panel is formed from two plate-shaped elements which are glued together, wherein only the first element is connected to the fastening element.
  • the elements can be glass panes which form, for example, a laminated glass pane. If the second element is located on the retaining clip, the retaining clip prevents slippage of this element in case of failure of the bond.
  • the Agraffe cost-effective with the retaining clip from an extruded profile, wherein the material of the agraffe is preferably an aluminum alloy.
  • the mounting arrangement 1 for a facade panel 3 has a facade panel 3, a fastening element 4, the first Agraffe 2 and a second Agraffe 5 for attachment to a substructure 6.
  • the substructure 6 is attached via a vertical support 7 to a supporting wall, not shown, of a building.
  • the substructure 6 comprises the vertical support 7 and two horizontally extending support 8 with an upwardly projecting web 9, on which the clasps 2, 5 are suspended and thus secured to the substructure 6.
  • the facade panel 3 consists of a first plate-shaped element 10, which is connected to a thermoplastic sheet 11 with a second plate-shaped element 12.
  • the plate-shaped elements 10, 12 are slices of a facade panel 3 made of laminated glass.
  • the facade panel 3 spans a plane E P , on which the axis of the fastening elements 4 formed as an undercut anchor 13 is substantially perpendicular.
  • the undercut anchors 13 are connected to the first plate-shaped element 10. They transmit the forces F O to the clasps 2, 5, which act orthogonal to the plane E P of the facade panel 3.
  • the undercut anchors 13 each have a spacer 19 and a round nut 20, which are screwed for mounting the undercut anchor 13 in a, introduced into the first plate-shaped element 10, undercut borehole 21 on a threaded bolt 22 of the undercut anchor 13.
  • the arranged on the facade panel 3 above agraffe 5 is L-shaped, with a vertically extending first web 14 and an adjoining, facing away from the facade panel 3 and horizontally extending second web 15, is formed.
  • a downwardly open, U-shaped suspension element 16 connects to the attachment of the second Agraffe 5 to the upper, horizontally extending support 8 at.
  • receiving device 18 is arranged, which receives the undercut anchor 13.
  • the receiving opening 17 is designed as a cylindrical bore 23, wherein the wall of the bore 23, the lateral surface 24 of the receiving opening 17 forms.
  • the diameter of the bore 23 of the receiving opening 17 is selected so that the diameter of the bore 23 is significantly larger than the diameter of the threaded bolt 22, whereby the fastening element 4 is not applied to the lateral surface 24 of the receiving opening 17.
  • the undercut anchor 13 can thus transmit no forces over the lateral surface 24 on the agraff 5.
  • the threaded bolt 22 is inserted into the receiving opening 17 and screwed with a washer 25 and a nut 26.
  • a spacer element 27 is disposed in the receiving opening 17.
  • the spacer element 27 is designed as a sleeve which receives the threaded bolt 22 and whose height is slightly greater than the wall thickness of the first web 14.
  • the washer 25 and the round nut 20 are clamped when screwing the nut 26 against the spacer element 27.
  • the first web 14, the round nut 20, the spacer 27 and the washer 25 together form a first sliding bearing 33.
  • the first Agraffe 2 is designed to accommodate the fastener 4 is the same as the second Agraffe 5, so that even in the first Agraffe 2 by the fastener 4 also only such forces F O are transferable to the Agraffe 2, orthogonal to the plane E P of Facade panel 3 act.
  • F P on the agraffe 2 which act parallel to the plane E P of the facade panel 3
  • the first Agraffe 2 of the mounting assembly 1 a retaining clip 28, the one piece, as an extension of the first web 14, L-shaped with a in the lower end of the facade panel 3 arranged cantilever 29 is formed as a bearing surface 30 on the agraffe 2.
  • the self-weight of the facade panel 3 is introduced via the support surface 30 in the retaining clip 28, and from there via the first web 14, the second web 15 and an adjusting element 16 arranged on the adjusting screw 31 in the horizontally extending support 8.
  • an intermediate layer 32 which reduces the friction between the facade panel 3 and the cantilever 29, it is ensured that the facade panel 3 can slide on the intermediate layer 32 at a temperature-induced change in length of the substructure 6, or the facade panel 3, and thus no significant Forcing forces due to friction arise.
  • the intermediate layer 32 forms with the facade panel 3 and / or the cantilever 29, a second sliding bearing 34th
  • the intermediate layer 32 is made of plastic, for example, while the clasps 2, 5 are preferably made of an extruded profile of an aluminum alloy.
