Abstract

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. A scaffold portion comprising a scaffold node and further scaffold elements.

First claim

The invention claimed is:

1 . A scaffold portion, comprising:
at least one scaffold node comprising: a connecting sleeve configured as a coupling point for two scaffold components comprising at least one vertical post, the connecting sleeve comprising a first half of the connecting sleeve and a second half of the connecting sleeve, the first half of the connecting sleeve being distinct from the second half of the connecting sleeve, a connecting disk configured to connect the scaffold node to further scaffold components or elements, the further scaffold components or elements comprising at least one horizontal bar or a horizontal strut, wherein the at least one connecting disk is distinct from the first half of the connecting sleeve and the second half of the connecting sleeve, wherein the connecting disk defines at least one inner projection that protrudes radially inwardly beyond an inner lateral surface of the connecting sleeve, wherein the at least one inner projection protrudes abruptly relative to the inner lateral surface of the connecting sleeve and has at least one load-absorption surface configured for absorbing loads oriented in the longitudinal direction of the connecting sleeve from a scaffold component, the at least one inner projection having a projection height from its outer edge adjacent to the inner lateral surface to its inner edge that is oriented radially toward the inside of the connecting sleeve, the connecting disk having a receiving surface defining an upper receiving surface and a lower receiving surface and having a plurality of receiving recesses, and the receiving recesses configured for connecting to the further scaffold components or elements, the connecting disk being rigidly connected to the connecting sleeve, the receiving surface being substantially perpendicular to the overall length of the connecting sleeve, and the connecting disk dividing the connecting sleeve into two parts such that the first half of the connecting sleeve is arranged below the connecting disk and an upwardly-facing end face of the first half of the connecting sleeve is rigidly connected to the lower receiving surface and the second half of the connecting sleeve is arranged above the connecting disk and a downwardly-facing lower end face of the second half of the connecting sleeve is rigidly connected to the upper receiving surface; the at least one vertical post insertable into the connecting sleeve of the scaffold node, wherein the vertical post defines at least one securing opening at an end close to the scaffold node, the securing opening corresponding in shape and size to a locking opening of the scaffold node; the at least one horizontal bar configured to be connected to the connecting disk of the scaffold node, or the horizontal strut configured to be connected to the connecting disk of the scaffold node; and a plug-in element configured to be introduced into the securing opening and the locking opening, the plug-in element being configured to both axially and radially secure the vertical post and scaffold node with respect to one another, wherein there is play between the plug-in element and the locking opening and/or between the plug-in element and the securing opening, so that the vertical post in the connecting sleeve is movable in the longitudinal direction of said sleeve within the limits of the play.

2 . The scaffold portion according to claim 1 , wherein the projection height is equal to or greater than a wall thickness of the connecting sleeve.

3 . The scaffold portion according to claim 1 , wherein the connecting disk is arranged centrally in the longitudinal direction of the connecting sleeve.

4 . The scaffold portion according to claim 1 , wherein the overall length of the connecting sleeve on each side of the connecting disk to the end of the connecting sleeve is greater than the sleeve diameter by the factor of 0.9 to 2.4.

5 . The scaffold portion according to claim 1 , wherein the plurality of receiving recesses, in the plan view on the connecting disk and the receiving surface, are arranged regularly at regular angles with respect to one another based on the axis of symmetry of the connecting sleeve, in the circumferential direction.

6 . The scaffold portion according to claim 1 , wherein the connecting sleeve has, at each end in its end regions, at least one locking opening which is directed radially inwardly through the wall of the connecting sleeve.

7 . The scaffold portion according to claim 6 , wherein the locking opening is arranged at a distance from the receiving surface of the connecting disk which corresponds at least to the factor of 0.5 of the sleeve diameter, the locking opening being arranged so as to be offset from the receiving recess at an angle of 45° in the circumferential direction of the connecting sleeve.

8 . The scaffold portion according to claim 1 , further comprising: the horizontal bar being form-fittingly connected to one of the receiving recesses in the connecting disk of the scaffold node, a shaped element arranged at the end of the horizontal bar being inserted into one of the receiving recesses and at least part of the horizontal bar end face facing the scaffold node abutting the connecting sleeve.

9 . The scaffold portion according to claim 1 , wherein at least one spindle nut post is provided which comprises a tubular post shaft with a spindle nut which is fastened thereto in an axially flush manner, the post shaft being inserted into the connecting sleeve.

10 . The scaffold portion according to claim 9 , wherein the end of the post shaft facing away from the spindle nut is supported on the inner projection.

11 . The scaffold portion according to claim 9 , wherein the length of the post shaft corresponds to a factor of from 0.5 to 0.8 of the overall length of the connecting sleeve.
