Abstract

The invention relates to a scaffold node for connecting scaffold elements extending in different spatial directions, comprising a connecting sleeve which is provided as a coupling point for two scaffold components, in particular for two vertical posts or for a vertical post and a spindle nut post, and at least one coupling element which is used to connect the scaffold node to further scaffold components or scaffold elements. The invention also relates to a scaffold portion comprising a scaffold node and further scaffold elements.

First claim

a connecting sleeve ( 2 ) which is provided as a coupling point for two scaffold components, in particular for two vertical posts ( 41 ) or for a vertical post ( 41 ) and a spindle nut post ( 304 ), at least one coupling element which is used to connect the scaffold node to further scaffold components or scaffold elements, wherein the connecting sleeve ( 2 ) has at least one inner projection ( 25 ) which protrudes radially inwardly beyond an inner lateral surface ( 26 ) of the connecting sleeve ( 2 ), wherein the at least one inner projection ( 25 ) protrudes abruptly relative to the inner lateral surface ( 26 ) of the connecting sleeve ( 2 ) and has at least one load-absorption surface ( 251 ) which is provided for absorbing loads oriented in the longitudinal direction of the connecting sleeve ( 2 ) from a scaffold component, and which has a projection height ( 28 ) from its outer edge adjacent to the inner lateral surface ( 26 ) to its inner edge that is oriented radially toward the inside of the connecting sleeve ( 2 ).

2 . Scaffold node ( 1 ) according to claim 1 , characterized in that the projection height ( 28 ) is equal to or greater than the wall thickness ( 27 a ) of the connecting sleeve ( 2 ).

3 . Scaffold node ( 1 ) according to either of the preceding claims, characterized in that the coupling element ( 3 ) is designed as a connecting disc, the connecting disc ( 3 ) having a receiving surface ( 31 ) having a plurality of receiving recesses ( 32 ), and the receiving recesses ( 32 ) being provided for being connected to further scaffold elements, such as horizontal bars ( 42 ) or diagonal struts, and the connecting disc ( 3 ) being rigidly connected to the connecting sleeve ( 2 ), and the receiving surface ( 31 ) being substantially perpendicular to the overall length ( 23 ) of the connecting sleeve ( 2 ).

4 . Scaffold node ( 1 ) according to either claim 1 or 2 , characterized in that the coupling element ( 301 a , 301 b ) is formed by two Cuplock elements that are collar-shaped, one Cuplock element ( 301 a ) being rigidly connected to the connecting sleeve ( 2 ) and the other Cuplock element ( 301 b ) being mounted so as to be axially displaceable relative to the connecting sleeve ( 2 ), and there being a gap between an inner diameter of the Cuplock elements ( 301 a , 301 b ) and the outer diameter of the connecting sleeve ( 2 ), into which gap an end piece of a horizontal strut ( 4001 ) can be introduced.

5 . Scaffold node ( 1 ) according to either claim 1 or 2 , characterized in that the coupling element is formed by a plurality, in particular four, wedge-locking pockets ( 302 ), a wedge-shaped end region of a horizontal strut ( 4002 ) fitting into a wedge-locking pocket ( 302 ), and it being possible to insert the wedge-shaped end region of the horizontal strut ( 4002 ) into the wedge-locking pockets ( 302 ) and to secure it therein.

6 . Scaffold node ( 1 ) according to either claim 1 or 2 , characterized in that the coupling element is formed by a disc washer ( 303 ) which is rigidly connected to the connecting sleeve ( 2 ), and a plurality of substantially wedge-shaped recesses are introduced into the disc washer ( 303 ) which penetrate the disc washer ( 303 ), the wedge-shaped recesses being provided to be connected to horizontally extending scaffold elements, such as a horizontal strut ( 4003 ).

7 . Scaffold node ( 1 ) according to claim 3 , characterized in that the at least one inner projection ( 25 ) is a part of the connecting disc ( 3 ), the connecting disc ( 3 ) dividing the connecting sleeve ( 2 ) into two parts, and the end face of each part of the connecting sleeve ( 2 ) being rigidly connected to a receiving surface ( 31 ) of the connecting disc ( 3 ).

8 . Scaffold node ( 1 ) according to claim 7 , characterized in that the connecting disc ( 3 ) has an in particular circular recess ( 39 ), and at least one portion outside this recess ( 39 ) forms the inner projection ( 25 ).

9 . Scaffold node ( 1 ) according to claim 3 , characterized in that the connecting sleeve ( 2 ) is made in one piece and the inner projection ( 25 ) is formed by an impression that extends radially around the circumference of the connecting sleeve, and the connecting disc is fastened to the outer lateral surface of the connecting sleeve ( 2 ).

10 . Scaffold node ( 1 ) according to any of the preceding claims, characterized in that at least one further inner projection ( 25 a ) is formed by indenting the wall ( 27 ) of the connecting sleeve ( 2 ), the further inner projection ( 25 a ) having a constant projection height ( 28 ) inside the connecting sleeve ( 2 ) in the longitudinal direction of the connecting sleeve ( 2 ), or the further inner projection ( 25 a ), starting from the inner lateral surface ( 26 ) of the connecting sleeve ( 2 ), rising steadily up to the projection height ( 28 ) and falling.

11 . Scaffold node ( 1 ) according to claim 10 , characterized in that the at least one further inner projection ( 25 a ) is designed as a longitudinal bead which extends over the overall length ( 23 ) of the connecting sleeve ( 2 ).

12 . Scaffold node ( 1 ) according to claim 11 , characterized in that two, preferably three, more preferably four further inner projections ( 25 a ) designed as longitudinal beads are provided which are distributed uniformly on the inner lateral surface ( 26 ) in the circumferential direction.

13 . Scaffold node ( 1 ) according to claim 10 , characterized in that the at least one further inner projection ( 25 a ) is designed as a stamping point which has a stamping center and which, starting from the inner lateral surface ( 26 ), steadily rises up to the projection height ( 28 ) in all radial directions around the stamping center, the projection height ( 28 ) being located in the stamping center.
