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 industry, comprising an outer tube (12) and an inner tube (14) axially displaceably arranged therein, said inner tube being secured by means of a fail safe against removal from the outer tube (12). The fail safe comprises a stop element which is arranged on the outer tube (12) and with which at least one stop means (48) arranged on the inner tube (14) can be brought in contact. According to the invention, the stop element is provided in the region of an end (20) of the outer tube (12) and covers the free cross-sectional surface of the outer tube (12) at least partially. The stop element is preferably designed as cap (22) and comprises an internal thread (26) that engages with an external thread (36) of the outer tube (12). The external thread (36) is in engagement with a recessed nut (38) on which a securing pin (40) can be supported, which can be guided through the outer and inner tubes (12,14) transversely to the longitudinal axis (30) of the telescopic support (10).

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...
