Embodiment Construction

[0025] figure 1 A selected column section of a telescoping column for the construction field, generally indicated at 10, is shown in . The telescoping strut 10 has an outer tube 12 and an inner tube 14 arranged axially displaceable in the outer tube. The inner tube 14 has a known bearing plate 18 on its free end 16 shown in the upper part of the figure, and the outer tube 12 has a bearing plate 18 on its base-side end, which is not shown in detail in the figure, for secure positioning. base plate on the corresponding bottom foundation.

[0026] A cover 22 is arranged on the top side of the outer tube 12 , that is, towards the end 20 of the support plate 18 of the inner tube 14 , which serves as a stop element for the inner tube 14 and prevents the inner tube 14 from the outer tube by means of the cover. 12 axially move out or fall out.

[0027] The cap 22 is configured in a manner corresponding to a cap nut and has an approximately cylindrical wall section 24 provided with ...

Abstract

The invention relates to a telescopic support (10) for the construction sector, comprising an outer tube (12) and an inner tube (14) arranged axially displaceable in the outer tube, the inner tube being prevented from moving out of the outer tube by means of a fall-off prevention device (12), the anti-falling device has a stop element arranged on the outer tube (12), and at least one stop device (48) arranged on the inner tube (14) can be attached to the stop element, According to the invention, the stop element is fastened in the region of the end ( 20 ) of the outer tube ( 12 ) and at least partially covers the free cross section ( 32 ) of the outer tube ( 12 ). The stop element is preferably designed as a cover ( 22 ). The external thread (36) engages with the drop nut (38) on which the locking that can pass through the outer tube (12) and the inner tube (14) transversely to the longitudinal axis (30) of the telescopic strut (10) screws (40).

Description

technical field [0001] The invention relates to a telescopic support for the construction sector, with an outer tube and an inner tube arranged axially displaceable in the outer tube, the inner tube being prevented from being removed from the outer tube by means of a fall-off prevention device, said fall-off protection The device has a stop element arranged on the outer tube, against which at least one stop means arranged on the inner tube can rest. Background technique [0002] Telescopic columns of this type are used in the construction industry for a variety of support tasks and are used, for example, as ceiling or installation columns for supporting concrete formwork. [0003] GB 755 831 A discloses a telescopic strut for the construction sector, wherein the stop element is formed by a tapering edge section of the end of the outer tube towards the telescoping end of the telescopic strut. In the telescopic strut according to EP 1 273 740 B1, the outer tube has a stop ele...
