Abstract

The invention relates to the fixing of a natural ashlar panel to a substructure with an anchor having an internal thread. The invention proposes that the corresponding blind hole be drilled to residual wall thickness R and the anchor be set in a recessed position. The natural ashlar panels with the anchors can thus be transported to the building site in the form of a compact stack. At the building site, a bolt having a stop element is mounted, which stop element is supported on the anchor. At the opposite end the substructure is clamped against the stop element. In that way, the distance of the outer surface of the natural ashlar panel from the substructure is constant even in the event of varying thicknesses D of the natural ashlar panels. As a result, laborious adjustment work is avoided.

First claim

The invention claimed is:

1. A combination, comprising:
an anchor for panel components, the anchor having an internal thread, and
a bolt, with an external threaded portion, which is complementary to the internal thread, and a load-application means for connection of the anchor to a substructure,
wherein
on the bolt, between the load-application means and the external threaded portion, there is arranged a stop element which is larger in diameter than the external threaded portion, wherein an axial thickness of the stop element is maintained when under a compressive load by the anchor and the load-application means,
a first axial end of the stop element that forms a first axially facing stop surface that faces the anchor and that is supported against the anchor, and
either the load-application means is a screw head and the stop element is longitudinally displaceable relative to the bolt, or the load-application means is a thread and the stop element is longitudinally immovable relative to the bolt and is larger in diameter than the load-application means,
wherein the first axially facing stop surface abuts either an axially facing surface formed by the anchor, or the first axially facing stop surface abuts an axially facing surface formed by a spacer that is sandwiched between the stop element and the anchor.

2. The combination according to claim 1 , wherein the stop element has the same diameter as or is smaller in diameter than an adjacent end of the anchor.

3. The combination according to claim 1 , wherein tool-application faces are arranged on the stop element.

4. The combination according to claim 1 , wherein tool-application faces are arranged on the load-application means.

5. The combination according to claim 1 , wherein the load-application means is a screw head and the stop element is longitudinally displaceable relative to the bolt.

6. The combination according to claim 1 , wherein the load-application means is a thread and the stop element is longitudinally immovable relative to the bolt and the stop element is larger in diameter than the load-application means.

7. The combination according to claim 1 , wherein the load-application means is an external thread.

8. A fixing arrangement, comprising:
a panel component having a hole extending in a first axial direction from an inner surface of the panel,
in which an anchor is anchored, the anchor having an internal thread,
a bolt, with an external threaded portion, which is screwed into the internal thread, and a load-application means,
and a substructure which is connected to the anchor via the load-application means of the bolt,
wherein
on the bolt, between the load-application means and the external threaded portion, there is arranged a stop element which is larger in diameter than the external threaded portion, wherein an axial thickness of the stop element is maintained when under a compressive load by the anchor and the load-application means,
a first axial end of the stop element that forms a first axially facing stop surface that faces an axially facing surface of the anchor and that is supported against the anchor, and
a second end of the stop element that forms a second axially facing stop surface that faces away from the anchor and that is supported against the substructure,
wherein the axially facing surface of the anchor is recessed in the first direction from the inner surface of the panel.

9. The fixing arrangement according to claim 8 , wherein the depth (T) of recess is from 1 to 6 mm.

10. The fixing arrangement according to claim 9 , wherein the depth (T) of recess is from 2 to 4 mm.

11. The fixing arrangement according to claim 8 , wherein the first end of the stop element, facing the anchor, is supported against a bearing shoulder of the panel component.

12. The fixing arrangement according to claim 8 , wherein the anchor is anchored in an undercut blind hole.

13. The fixing arrangement according to claim 8 , wherein the first axially facing stop surface abuts either the axially facing surface formed by the anchor, or the first axially facing stop surface abuts an axially facing surface formed by a spacer that is sandwiched between the stop element and the anchor.

14. The fixing arrangement according to claim 8 , wherein the stop element has the same diameter as or is smaller in diameter than an adjacent end of the anchor.

15. The fixing arrangement according to claim 8 , wherein the panel is a stackable panel.

16. The fixing arrangement according to claim 8 , wherein the anchor is anchored in an undercut blind hole of the panel.
