• the fastening element shown in DE-A1-32 37 294 serves for the overlapping arrangement of the facade panels.
• AT-B-372 134 describes a fastening device in which strips or tabs for receiving fastening screws on the side surfaces of facade elements Raenten are arranged, each with a spring element is provided to prevent the falling out and unintentional rotation of the screw. To achieve this, the spring element presses the screw head against the tab or bar.
• the object of the invention is therefore to provide fastening elements for fastening facade panels to building walls which are simple and quick to assemble, free adjustability in the three mutually perpendicular directions being possible, even after their pre-assembly , and errors due to incorrect or careless handling are minimized or largely excluded.
• the movability of the bolt can be determined and controlled via a self-clamping or snap-on device.
• Spring elements as a clamping device enable, via their spring legs projecting beyond the pin axis, their convenient handling even with lower or side plates already in place before the adjacent plates are installed.
• Measures to increase stability such as the body of the fastening element provided with beads or support, or guidance by double mounting of the bolt, reduce the risk of the fastening element bending under load.
• the mounting of the fastening element on the wall is simplified in that a slot-shaped recess is provided on the holding part thereof, via which the fastening element is inserted into the wall after the dowel screw has been screwed in and because of the cantilevered edges that come into engagement with one of the dowel screws can be hooked in and rotated or shifted vertically as required.
• the holding part and / or the holding washer can be designed with a rough surface, so that after tightening the dowel screw, a frictional fit is obtained.

• FIG. 1 shows a fastening element according to the invention for fastening facade panels in an oblique view, for which FIG. 2a shows a cross section of the fastening element mounted on a wall 2.
• the fastening element has a body 3 with an approximately b-shaped cross section.
• this body 3 is made of a heavy sheet metal profile - optionally bent in one piece and - as shown in FIG. 1 - may have beads 16 formed therein.
• the fastening element is fixed to the wall 2 by means of a dowel screw 4, the dowel screw 4 being inserted through a slot-shaped recess 13 in a flat holding part 5 of the fastening element which comes into contact with the wall 2.
• This mandrel 8a engages in recesses 9 'and 9 "which are provided in the facade panels 1' and 1", with two facade panels 1 'and 1 "- in 2a a lower 1 'and an upper facade panel 1 "- are fixed to each other via this mandrel 8a.
• the bolt 7 is displaceably mounted in the offset part 6 along its longitudinal axis 7c, to secure the horizontal position of the bolt 7 when the facade panels 1 ', 1 "are mounted, a further bearing 11 of the same is provided, here as a bent-up part punched out of the offset part 6 In the same way, the fastening element as such is also supported against the wall 2.
• a support 17 is formed on the bow-shaped, offset part 6 in order to minimize its deflection when the facade panels are attached.
• the mobility of the bolt 7 can be controlled via a clamping device in the form of a leaf spring 10a.
• a clamping device in the form of a leaf spring 10a.
• the leaf spring 10a In the relaxed state, the leaf spring 10a is seated to inhibit the movement of the bolt 7, and to clamp it firmly, since it projects through a recess 18 in part 6 and is thus arranged in a stationary manner relative to the latter. If, on the other hand, the leaf spring 10a is compressed, the clamping on the bolt 7 is released and the latter is displaceable.
• a flange-like widening, optionally riveted, provided on the free end 7b of the bolt 7 facing the wall 2 serves as a safeguard 12 against the bolt 7 being pulled out, if necessary carelessly.
• FIG. 1a shows an alternative embodiment to FIG. 1, in which the body 3a is double-walled, and the load-bearing capacity of the fastening element thus becomes particularly high.
• the bolt 7 is guided in both parts of the body wall.
• the dowel screw 4 is approximately in the middle, ie essentially above the dimension of the fastening element, ie above a recess 9' provided in this panel 1 ' predetermined distance screwed into the wall 2.
• the fastening element is then inserted into the upwardly open slot 13 on the holding part 5 from below, a holding washer 15, which sits on the dowel screw 4, the fastening element due to the projecting, upper edges 14a and 14b of the wall parts 5a and 5b provided on both sides of the slot 13 holds the holding part 5 until the final fixing of the fastener.
• the pin 7 is displaceable by relaxation of the leaf spring 10a and the mandrel 8a is inserted with its downwardly facing end into the recess 9 'of the lower facade panel 1. 1 Any necessary corrections, for example due to a slight inclination of the plate with respect to the horizontal or vertical alignment, can be carried out by a new displacement or slight rotation of the bolt 7 and thus the mandrel 8a.
• FIG. 3a and 3b show an embodiment variant of a fastening element according to the invention, in which a leaf spring 10b is provided as the clamping device, which laterally engages in a corrugation 7d attached to the bolt 7.
• a leaf spring 10b is provided as the clamping device, which laterally engages in a corrugation 7d attached to the bolt 7.
• the clamping device is designed as a wire spring 10c engaging in the corrugation 7d, will also be suitable for less heavy facade panels, and their structural depth is also less than in the variant shown above.
• the size, strength and type of the clamping device and the dimensions of the body of the fastening element are to be determined depending on the weight, size and number of the facade panels used, since the tensile and compressive forces acting on the facade panels must be reliably absorbed.
• FIG. 5 shows an extension 8 ', which is designed as a cross member and carries two mandrels 8a, which engage in a slot-shaped recess in the facade panel.
• the approach 8 ' can optionally perform a carrying function if designed as a cantilevered carrier profile.
• Double-angle shape formed, possibly stabilizing the weak points of the recess in thin plates. It
• the facade panels can also be installed overlapping, whereby (Fig. 7) - especially with very thin facade panels - there is no need for recesses in the facade panels that tend to break out (there will then be no spike on the extension).
• FIG. 8 shows an essentially known fastening element with a screw-shaped bolt and a screw nut 19 lying on the outside of the bow-shaped part 6s, which has a slot-shaped recess 13s on its holding part 5s, such as the assembly and positioning as shown above with reference to FIG. 2b known systems by hanging in the wall 2 pre-assembled dowel screws 4 facilitating.
