The invention relates to an expansion dowel with an expandable section and a further section for fastening of cladding elements or components on a wall or the like., The expandable section in a borehole the wall insertable and therein for its attachment by driving in a head having Spreading element spreadable from the free end of the dowel is, and the other section engages with its end in the 3 component to be fastened and this with the end having a flange-like extension that can be covered by a cap from its outer surface Recorded. ■

The invention aims at a further embodiment of the subject matter according to the main patent in order to expand its application possibilities.

There are cladding elements or components known in which the making of recesses for receiving

of the head of the expansion element is not possible. There are cladding elements that consist of two thin metal plates that form the outer surfaces and that enclose an insulating material between them. Making a recess for receiving the head is understandably not possible in the thin plates, since the depth of the recess required to accommodate the wax can be _{a multiple of the plate thickness f.} The well-known posting of the

Plate for forming a recess can also be retrofitted to these cladding elements not perform. The placement of the head of the expansion element directly on the surface of the Metal plate is undesirable because of the risk of contact corrosion «

The object of the present invention is therefore to design the dowel according to the main patent in such a way- * that it is suitable for the application cases described above 'Is suitable and the expansion element by with his head Dowel is well guided and protected against corrosion.

According to the invention this is achieved in that the flange-like approach on its to the further section ■ ■ '. facing side by a right-angled to the dowel, / axially directed surface is limited, a substantially cylindrical outer shape with preferably circular Has cross section and has a recess corresponding to the head shape of the expansion element.

The flange-like approach is due to its right angles directed contact surface directly on the outer surface

of the cladding element or the component to be fastened, while in the head shape of the expansion element adapted recess of the head is added so that an effective attachment of the Cladding panel or the component is ensured. By receiving the head in the recess is this protected against corrosion and external damage, which is further reduced by the attachable cap

In addition to the invention, the recess for receiving a countersunk head arranged on the expansion element be conically tapered.

This configuration makes it possible for the cladding panels described above and to be fastened Components to use wood screws as expansion elements, which are usually provided with a countersunk head are. Only through the design of the expansion anchor according to the invention has it become possible to use such wood screws with countersunk head for fastening '»') these cladding elements.

An exemplary embodiment of the invention is shown in the drawing.

The dowel 2 has a flange-like extension 7 which has a substantially cylindrical outer shape owns. The surface 15 »which has the flange-like approach 7 to the outer surface of the component 3 to be fastened

Inside the flange-like extension 7 a recess 8 is provided which corresponds to the shape of the head 9 of the expansion element 10. the Cover cap 11 can be slipped over the flange-like extension. The component 3 to be fastened consists from the outer plate 16 and the inner plate 17, an insulating material 18 is enclosed between the two. - sen.

The invention is not limited to the illustrated embodiment. So are others of that Circular shape deviating cross-sectional shapes of the flange-like approach conceivable. The countersunk head can also have a different education. Finally, it is also possible to use the components or cladding panels also to be arranged at a distance from the wall. This can be done using special spacer elements. It but it is also possible to arrange stop means on the dowel, which are spaced apart from the cladding panel hold off the wall surface.
