Definitions

  • the invention relates to a facade covering comprising facade panels which can be connected to one another by means of a tongue and groove connection, and at least one support element which acts as a storm protection device, the facade panels being formed at least partially by a metal sheet forming the visible surface, which is attached to the end faces to form the groove - and of the tongue profile is profiled, and wherein the metal sheet forms a fastening section, which extends under the adjacent facade panel in the connected state to the tongue profile, for fastening the facade panel to the substrate, and wherein the support element is arranged on the fastening section and has a Has groove profile of the adjacent facade panel engaging behind stop.
  • Tongue and groove connections are often used to join together board-like, in particular large-area components such as panels, floor elements or boards to form large areas.
  • the tongue and groove profile on the end faces is usually bent out of the edge areas of the metal sheet.
  • the tongue and groove connection is intended to achieve a connection with as few open butt joints as possible, so that the structure covered by the board-like components can be reliably protected from environmental influences.
  • the facade panels are fastened to a facade with the aid of fastening means.
  • the fastening is not usually effected directly on the facade, but rather on elongate holding elements arranged on the facade, which can be designed, for example, as carrier profiles made of steel, aluminum or wood.
  • the support element can be arranged on a facade panel in such a way that it engages behind the groove profile of an adjacent facade panel and thereby forms a stop that makes it difficult for the tongue profile to emerge from the groove profile.
  • the support element has to be arranged at a distance from the groove profile of the adjacent facade panel in order to enable the production of the tongue and groove connection, ie the tongue and groove can be pushed into one another.
  • the document EP 636 752 A1 discloses an arrangement of facade panels which can be connected to one another by means of a tongue and groove connection.
  • the documents EP 2 251 500 A1 as EP 0 133 146 A2 also disclose facade panels or an arrangement of facade panels with tongue and groove connections.
  • the latter document discloses a facade cover according to the preamble of claim 1.
  • the present invention therefore aims to improve a storm protection for facade panels in such a way that the detachment of individual facade panels is reliably prevented even with high wind suction loads, without the assembly of the facade panels, in particular the sliding of tongue and groove into one another is made more difficult.
  • the invention in a facade covering of the type mentioned essentially provides that the stop of the acting as a storm protection Support element is held resiliently deflectable and that the support element has a first leg rigidly arranged or arrangeable on the fastening section of the facade panel and a second leg that can be deflected, in particular pivoted, relative thereto, the stop being formed on the second leg. Due to the fact that the stop is held in a resiliently deflectable manner, several effects are achieved at the same time. On the one hand, the resiliently deflectable arrangement of the stop means that the stop can be pressed against the groove profile under a spring force, which in turn causes an additional attachment or wedging of the groove profile relative to the tongue profile.
  • the resiliently deflectable arrangement of the stop allows it to be pushed away to make it easier to slide in the tongue and groove profile during insertion. When pushed away, free space is created for the tongue and groove profile to slide into one another, with the stop being able to return resiliently to its original position after the tongue and groove connection has been made, in which the stop assumes a position that engages behind the groove profile.
  • the stop has a first stop surface that interacts with the groove profile of the adjacent facade panel in order to exert a holding force acting perpendicularly to the first stop surface, and that the stop can be deflected in a direction running transversely to the holding force.
  • the stop has a second stop surface which interacts with the groove profile of the adjacent facade panel and can be pressed resiliently against an underside of the groove profile.
  • the first stop surface of the stop thus serves to provide a holding force acting transversely to the direction of deflection of the stop.
  • the first stop surface is arranged in such a way that it counteracts the tongue profile being pulled apart relative to the groove profile.
  • the stop is preferably designed in such a way that the first stop surface has essentially no movement component in the direction of the holding force.
  • a particularly effective securing of the tongue and groove connection is achieved according to a preferred embodiment in such a way that the stop, in particular the first stop surface, is arranged to be in contact with one another connected state of the facade panels to lie on the groove profile of the adjacent facade panel.
  • the second stop surface of the deflectable stop has a movement component in the direction of the holding force, i.e. perpendicular to the second stop surface, so that the stop with the second stop surface can be pressed against the underside of the groove profile.
  • a preferred embodiment provides that the section of the groove profile that can be contacted by the second stop surface of the stop runs inclined relative to the corresponding section of the tongue profile, so that wedging is promoted.
  • the structural design of the support element according to the invention provides that the support element has a first leg that is or can be arranged rigidly on the fastening section of the facade element and a second leg that can be deflected, in particular pivoted, relative thereto, with the stop being formed on the second leg.
  • the support element is essentially U-shaped or V-shaped in cross section.
  • the resilient design of the stop can be achieved in that the two legs are connected to one another via an elastic connecting section.
  • the two legs can be formed in one piece with one another, with the deflection or connecting section forming the U or V shape being elastic.
  • the support element can be made of spring steel or the like.
  • the stop is formed by an end section of the second leg that is bent into a step.
  • the second leg has stiffening means, preferably beads, extending in the longitudinal direction of the leg.
  • stiffening means preferably beads
  • a preferred embodiment provides that the second leg has beveled lateral surfaces, and that the second leg may also have at least one rounded transition area between the first abutment surface and the leg region adjoining this.
  • the rounded areas in particular in the front area of the second leg, in particular in the area immediately adjacent to the stop, serve on the one hand to facilitate insertion of the groove profile and on the other hand to enable the façade panels to be moved laterally without tilting.
  • the support element according to the invention can be designed either as a separate component from the facade element or in one piece with the fastening section of the facade panel be trained. In the former case, the support element can be made available preassembled with the fastening section or assembled separately on site.
  • the supporting element is designed as an element that is separate from the facade panel and has a recess for a connecting means, in particular a screw. Because the supporting element has a recess for a connecting means, in particular a screw, one and the same connecting means can be used to connect both the supporting element to the fastening section and the fastening section to the substrate.
  • the support element is placed on the fastening section in such a way that the recess of the support element is aligned with a recess formed in the fastening section, so that the connecting means, in particular a screw, can be inserted through both recesses.
  • the recess is formed in the first leg and that the second leg has a further recess aligned with the recess.
  • the further recess formed in the second leg serves to insert the connecting means from above into the recess of the first leg.
  • the further recess is formed with a larger diameter than the recess formed in the first leg, in order to allow a screw head, for example, to pass through.
  • the support member additionally functions as a washer and reduces due to the greater surface pressure, the buttoning of the screw on the facade panel.
  • the recess formed in the first leg can in this case be formed as a slot in order to be able to set the longitudinal position of the stop relative to the groove profile and, for example, to be able to adapt it to the material thickness.
  • FIG. 1 shows 1 a formation of facade panels according to the state of the art, 2 the connection of two adjacent facade panels using a support element according to the invention, 3 a perspective view of the support element according to FIG 2 , 4 a view of the support element according to the arrow IV 3 and 5 a sectional view of the support member along the line V - V of 4 .
  • a first facade element is denoted by 1 and a second facade element by 2 .
  • the first and the second facade element 1, 2 are each formed from a metal sheet and have a groove profile 3 or a tongue profile 4 on the end faces.
  • the tongue profile 4 is pushed into the groove profile 3 and held in it in a form-fitting manner.
  • Adjoining the spring profile 4, the metal sheet forms a fastening section 6, with which the facade panel 1 or 2 can be fastened to a substrate (not shown).
  • the attachment can be done, for example, using at least one screw.
  • a support element 7 with a stop 8 is provided on the fastening section 6 , which engages behind the groove profile 3 of the facade element 2 .
  • the support element 7 comprises a first leg 9 and a second leg 10, which are connected to one another via an elastic connecting section 11 to form a V-shaped cross section.
  • the first leg 9 is rigidly connected to the base 13 with the aid of a screw 12 which also passes through a recess in the fastening section 6 .
  • the second leg 10 is held resiliently deflectable relative to the first leg 9 with the aid of the elastic transition section 11 in the direction of the double arrow 14 .
  • the second leg 10 has a stop 8 which comprises a first stop surface 15 and a second stop surface 16 . At least one rounding 17 is provided at the transition from the first stop surface 15 to the adjacent section of the second leg 10 .
  • the first stop surface 15 and the second stop surface 16 are arranged at an angle of approximately 90° to one another, with, as in FIG 2 As can be seen, the first stop surface 15 bears against a vertical section of the groove profile 3 and the second stop surface 16 can be pressed resiliently from below against a section of the groove profile 3 which is essentially horizontal or slightly inclined to the horizontal. This effectively prevents the tongue and groove profile from being pushed apart and causing a façade panel to become detached from the panel assembly.
  • the first leg 9 has a recess 18 through which the screw 12 can be inserted.
  • a further recess 19 is formed in the second leg 10, the diameter of which exceeds the screw head diameter ( 3 ).
  • the beveled side surfaces of the second leg 10 cause the facade panels 1, 2 to be moved laterally without tilting.
  • façade panel includes any panel-like cover elements that are suitable for covering a building or parts thereof.
  • the term “facade panel” is therefore not to be understood to the effect that the invention is limited to panels that are provided for covering facades, but also extends to panels that cover other components of a building.
