The invention relates to a façade structure according to the preamble of Claim 1.
Façade structures with a sub-structure formed from vertical and/or horizontal profiled supports are known, said sub-structure being located in front of a building wall or being anchored in a fixed manner in the ground or in the building wall. Façade panels made from ceramic material, preferably clay material, are secured to the sub-structure via panel holders.
The panel holders, as a rule, are H-shaped in cross section, that means they have an upwardly open U-shaped section receiving means and a downwardly open U-shaped section receiving means. The façade panels are inserted into the panel holders such that they engage in the upwardly open U-shaped receiving means with their foot fold and in the downwardly open U-shaped receiving means of the panel holder with their head fold.
It is known that the H-shaped panel holders are secured in the vertical profiled supports by means of screws. As a rule, the vertical profiled supports are realized as T-sections. Their rear flange faces the building wall and there is secured via corresponding supports to horizontal profiled supports of the sub-structure or directly to the wall. The front T-shaped flange is for screw-connecting the panel holders. To date there are three systems in practice in conjunction with the screw-fastening. In the one case, the securing flange of the T-section is unpunched. The panel holder is secured in the respectively selected position by means of drilling on site. In the other case, securing holes are already located in the securing flange in a grid arrangement in a vertical row of holes. This means that it is not possible to adjust the position of the panel holder in a stepless manner but simply within the grid spacing of the row of holes. In the case of the third system, an undercut false channel for the panel holders is realized on the front side of the securing flange of the vertical T-section. For securement, it is also necessary in this case for the securing hole to be drilled on site. The panel holder has to be threaded into the undercut false channel in each case from the upper or from the lower end, which makes the assembly more difficult.
It is the object of the present invention to provide an improved façade structure, making simple securement and alignment of the panel holder possible.
This object is achieved according to the invention with the object of Claim 1. Proposed is a façade structure, preferably a curtained, rear-ventilated façade structure, having a sub-structure that is formed from vertical and/or horizontal profiled supports, is located in front of a building wall and/or is anchored in a fixed manner in the ground or in the building wall, having façade panels made of ceramic material, preferably clay material, that are secured to the sub-structure via panel holders. The panel holders each have on their front side at least one receiving means for a lower edge, preferably a foot fold of a façade panel, or for an upper edge, preferably a head fold of a façade panel, and at their rear side a securing flange for securement to the sub-structure. It is provided in this case that, for securing the panel holder to the sub-structure, the sub-structure has a vertical flange, in which a vertical row of holes is realized by a plurality of elongated holes located one above another, wherein the elongated holes each extend in an angled manner, preferably at an acute angle to the horizontal, and are located in a parallel or angled manner one relative to another, and the row of holes is located between two parallel extending guide ribs, which protrude forward from the vertical flange. It is additionally provided in this case that the securing flange of the panel holder is insertable in an engaging manner between the guide ribs and has at least one elongated hole, which extends at an angle to the horizontal that is not identical to the angle of a plurality of elongated holes, preferably of all the elongated holes of the row of elongated holes realized in the vertical flange of the sub-structure, such that the elongated hole in the securing flange of the panel holder intersects at least one of the elongated holes of the row of holes of the vertical flange of the sub-structure. It is provided in this case that, for securing the securing flange of the panel holder to the front flange of the sub-structure, a securing element is insertable and/or securable in the intersection region of the elongated holes.
It is essential to the invention that one or more vertical rows of holes are located in the vertical profiled support of the sub-structure, said rows of holes each comprising elongated holes that extend inclinedly in parallel. If said elongated holes are located inversely to the elongated hole in the securing flange of the panel holder, it is possible to adjust the intersection point with the elongate hole of the vertical profiled support of the panel holder over the entire vertical region of each elongated hole of the vertical profiled support by the panel holder being displaceable in its vertical position as long as the securing element is not yet inserted. When the panel holder is displaced in this manner, the intersection point of the two elongated holes moves up or down in the elongated hole of the vertical section. As soon as the securing element is inserted, the intersection point is fixed. The panel holders are therefore secured to the vertical profiled supports of the fixed sub-structure in this manner.
In the case of the present invention, the position of the panel holder can be adjusted steplessly at least in a sectional manner and it is also not necessary to drill on site. Securement can be effected by means of an arbitrary securing element that is simply inserted into the respective intersection point of the elongated holes. As described above, the vertical position of the intersection point can be adjusted steplessly by vertical displacement of the panel holder guided between the guide ribs before the securing element is inserted. Once the securing element has been inserted, the position of the panel holder is fixed.
Consequently, a substantial advantage of preferred exemplary embodiments of the invention is in the, at least in sections, stepless adjustability of the vertical position and of the securement of the panel holders. A rivet is preferably used for securing the panel holder on the profiled support. A rivet gun is used as the tool for mounting the rivet. However, it is also possible to use a screw, preferably self-tapping, to secure the panel holder. A cordless screwdriver is preferably used as the tool for this purpose.
It can be provided that the angle of the elongated hole in the securing flange of the panel holder is realized inversely to the angle of the elongated holes of the row of holes in the vertical flange of the sub-structure.
In an advantageous embodiment it can be provided that the angle of the elongated holes of the row of holes in the vertical flange of the sub-structure is +45° or −45° to the horizontal and/or that the angle of the elongated hole in the securing flange of the panel holder is −45° or +45° to the horizontal.
It can also be provided that the elongated holes of the row of holes in the vertical flange of the sub-structure are located in a grid arrangement.
It is also possible that the elongated holes of the row of holes in the vertical flange of the sub-structure cover a vertical section of the vertical flange of the sub-structure, said section being equal to the grid spacing or smaller than the grid spacing of the elongated holes.
The grid spacing can preferably be smaller or equal to the sum of the width of the elongated hole and the quotient from the grid spacing and double the sine of the width of the elongated hole. In this case, the panel holder can be mounted at any arbitrary vertical position on the sub-structure.
It can be provided that the securing element is realized as a securing screw or securing pin, for example a bolt, rivet or screw. The securing element is preferably realized such that a press-type and/or clamp-type connection is realized in the point of intersection of the elongated holes and the securing flange of the panel holder is pressed against the vertical flange of the sub-structure such that the securing flange of the panel holder and the vertical flange are each held together between two stop members. A rivet is preferably used as the securing element, however, self-tapping screws can also be used in an advantageous manner. In principle, it is also possible to use screws with nuts.
In addition it can be provided that the width of the elongated hole of the securing flange of the panel holder is equal to the width of the elongated hole of the row of holes in the vertical flange of the sub-structure and said width corresponds to the diameter of the securing element. It is assumed here that nominal sizes are used in each case and that a clearance fit is realized between the nominal sizes so that the securing element is insertable without the aid of a tool, for example a hammer.
