Facade fastening system having profile elements
A profile element for attachment to the rear side of a façade panel, which in turn is fastened to a base such as a building surface or substructure. The profile element is formed in one piece and includes three functional sections arranged one after another: a fixing section for fixing the profile element to a base; a support section for attachment to the façade panel; and a spacer element which, in the installed state, ensures the correct distance between the base and the rear side of the façade panel. The profile element is extendible by a supplementary element, which has functionally similar elements and is only used if required by the geometry of the façade panel. The supplementary element is usable for positive connection to the profile element of an adjacent façade panel. Such a façade system provides flexibility for a wide variety of types and dimensions of façade panels.
1 . A profile element ( 10 ) for attachment to a rear side ( 2 ) of a façade panel ( 1 ) and fastening to a base ( 5 ), the profile element ( 10 ) comprising:
an integrally formed single piece comprising a fixing section, a support section, and a spacer element ( 20 , 30 , 40 ) arranged one after another,
the fixing section ( 20 ) being configured for contact with and fixing to the base ( 5 ),
the support section ( 30 ) being configured for attachment to the rear side ( 2 ) of the façade panel ( 1 ), and
the spacer element ( 40 ) forming a spacer that is configured to only dissipate compressive forces that occur to ensure a correct distance between the base and the rear side of the façade panel in an installed state,
wherein the support section ( 30 ) has a substantially flat, planar fastening surface ( 32 ) which, in the installed state, lies at least one of flush or positively against the rear side ( 2 ) of the façade panel ( 1 ).
2 . The profile element ( 10 ) according to claim 1 , wherein the support section ( 30 ) has through-holes ( 34 , 34 ′) configured for receiving at least one of screws, rivets, or threaded bolts, which are provided for connecting the profile element ( 10 ) and the façade panel ( 1 ).
3 . The profile element ( 10 ) according to claim 1 , wherein the fixing section ( 20 ) has at least one of a marking ( 23 ) for self-drilling screws or a through-hole or receptacle ( 24 ) for a fastener for connecting the profile element ( 10 ) to the base ( 5 ).
4 . The profile element ( 10 ) according to claim 1 , wherein the fixing section ( 20 ) has a substantially flat, planar contact surface ( 22 ) which, in the installed state, lies flush with the surface of the base ( 5 ).
5 . The profile element ( 10 ) according to claim 4 , wherein the fixing section ( 20 ) further comprises an edge region ( 26 ) which tapers outwards in a tongue shape and recedes from a plane ( 25 ) of the contact surface ( 22 ), thus forming a groove ( 27 ) between the fixing section and the base in the installed state.
6 . The profile element ( 10 ) according to claim 5 , wherein the groove ( 27 ) has a substantially rectangular, wedge-shaped or rounded profile in cross-section.
7 . A two-part profile element combination, comprising:
the profile element ( 10 ) according to claim 1 ;
a supplementary element ( 50 ) formed in one piece and comprising a spacer ( 60 ), a support area ( 70 ) and a connecting section ( 80 ) arranged one after another, the spacer ( 60 ) acts only as a spacer member and dissipates compressive forces that occur, which in the installed state ensures the correct distance between the base and the rear side of the façade panel, the support area ( 70 ) is configured for attachment to the rear side of the façade panel; and
the connecting section ( 80 ) comprises a pin ( 84 ) at one end and a contact surface ( 82 ) to the base ( 5 ), and the pin ( 84 ), in the installed state, permits positive engagement in a groove ( 27 ) formed by the fixing section of the profile element ( 10 ) with the base ( 5 ).
8 . The profile element combination according to claim 7 , wherein at least one of the profile element ( 10 ) or supplementary element ( 50 ) is extruded from aluminum, are formed or assembled from bent sheet metal parts or are produced as plastic injection molding elements.
9 . A façade system for mounting façade panels on a base ( 5 ), the system comprising façade panels as well as the profile element according to claim 1 .
10 . The façade system according to claim 9 , wherein, in the installed state, vertically measured distances of horizontal edges of two adjacent façade panels from one another are selected such that a gap formed is configured for insertion and actuation of a fastening or loosening tool for a fastener ( 7 ) which forms a fastening point between the profile element ( 10 ) and the base ( 5 ) in a region of the fixing section.
11 . The façade system according to claim 9 , wherein a length of a fastener ( 7 ) is selected shorter than a clear width (d) between mutually facing and opposing surface sections of the fixing section ( 20 ) and the support section ( 30 ).
12 . The façade system according to claim 9 , wherein the façade panel ( 1 ) is at least one of a decorative element, a cover panel, a solar panel, a light or lighting element, a thermal collector or radiation element, a sound insulation element, a display element, or a sensor surface.
13 . The façade system according to claim 9 , wherein the base is a building surface or a substructure.
14 . A façade system for mounting façade panels on a base ( 5 ), the system comprising façade panels as well as the profile element combination according to claim 7 .
15 . The façade system according to claim 14 , wherein connection between the façade panel ( 1 ) and at least one of the profile element ( 10 ) or the supplementary element ( 50 ) is made by at least one of screws, rivets, threaded bolts, or glue.
