Spindle strut

Abstract

A spindle strut comprises a support rod element which is elongated in the direction of a longitudinal axis and has a first axial end portion and a second axial end portion, a spindle nut element which can be rotated about the longitudinal axis with respect to the support rod element, wherein the spindle nut element is held at the first axial end portion of the support rod element in both axial directions against axial movement with respect to the support rod element, so that rotation of the spindle nut element about the longitudinal axis essentially does not result in an axial movement of the spindle nut element with respect to the support rod element, a spindle rod element which is elongated in the direction of the longitudinal axis, wherein the spindle rod element is in threaded engagement with the spindle nut element, so that rotation of the spindle nut element about the longitudinal axis results in an axial movement of the spindle rod element with respect to the support rod element.

1 . A spindle strut, comprising:
 a support rod element elongated in the direction of a longitudinal axis with a first axial end portion and a second axial end portion,   a spindle nut element rotatable about the longitudinal axis with respect to the support rod element, wherein the spindle nut element is held at the first axial end portion of the support rod element against axial movement in both axial directions with respect to the support rod element, so that a rotation of the spindle nut element about the longitudinal axis does not essentially result in an axial movement of the spindle nut element with respect to the support rod element,   a spindle rod element elongated in the direction of the longitudinal axis, wherein the spindle rod element is in threaded engagement with the spindle nut element, so that rotation of the spindle nut element about the longitudinal axis results in an axial movement of the spindle rod element with respect to the support rod element.   
     
     
         2 . The spindle strut according to  claim 1 , wherein the spindle nut element has an internal spindle thread, and the spindle rod element has an external spindle thread in threaded engagement with the internal spindle thread. 
     
     
         3 . The spindle strut according to  claim 2 , wherein the spindle rod element has a spindle rod threaded portion having the spindle external thread and a spindle rod coupling portion adjacent the spindle rod threaded portion. 
     
     
         4 . The spindle strut according to  claim 3 , wherein the spindle rod threaded portion is designed as a tube or as a solid component, and/or in that the spindle rod coupling portion is designed as a tube, and/or in that the spindle rod threaded portion is connected to the spindle rod coupling portion by material connection. 
     
     
         5 . The spindle strut according to  claim 1 , wherein the support rod element is tubular at least in the region of its first axial end portion and in that the spindle rod element, which is in threaded engagement with the spindle nut element, engages in the support rod element in the region of its first axial end portion. 
     
     
         6 . The spindle strut according to  claim 1 , wherein a support rod element end face is provided on the first axial end portion of the support rod element, and in, that on the spindle nut element, a spindle nut support surface is provided, which is supported, in a first axial direction, on the support rod element end face towards the first axial end portion of the support rod element. 
     
     
         7 . The spindle strut according to  claim 1 , wherein, on the first end portion of the support rod element, a support rod element support surface is provided, which is oriented towards the second axial end portion of the support rod element and which extends around the circumference, and in that the spindle nut element is supported with at least one spindle nut support portion in a second axial direction away from the second end portion of the support rod element. 
     
     
         8 . The spindle strut according to  claim 7 , wherein, on the first axial end portion of the support rod element, a support flange is provided, which provides the support rod element support surface, and extends around the circumference. 
     
     
         9 . The spindle strut according to  claim 6 , wherein the support flange is arranged at an axial distance from the support rod element end face. 
     
     
         10 . The spindle strut according to  claim 7 , wherein at least two spindle nut support portions are provided on the spindle nut element, arranged at a circumferential distance from one another. 
     
     
         11 . The spindle strut according to  claim 7 , wherein the spindle nut element has, in association with at least one spindle nut support portion, a spindle nut actuation portion which protrudes radially outwards from a spindle nut central region and carries a spindle nut support portion. 
     
     
         12 . The spindle strut according to  claim 1 , wherein at least one coupling element is provided on the support rod element and/or on the spindle rod element. 
     
     
         13 . The spindle strut according to  claim 12 , wherein the at least one coupling element is designed as a perforated disk, and/or in that at least one coupling element is designed as a pass-through opening. 
     
     
         14 . A support structure, comprising at least two structural elements supported by at least one spindle strut according to  claim 1 . 
     
     
         15 . The support structure according to  claim 14 , wherein the support structure is a scaffolding, and/or in that the support structure is a formwork structure.
