For example, when a grating is uncovered, its surroundings must be secured against the risk of falling. Since barrier tapes or barrier chains are not permitted for this purpose, barriers are usually constructed from wood, for example from square timber and boards attached to it. The assembly and disassembly of such securing devices is labor-intensive, and there is a risk of injury to the Mon expensive from wood splinters and handling tools.

Support posts and railing struts form the modules from which the quick release railing can be constructed.

  • the opening in the base plate is preferably located close to the shaft of the foot part. In this case, the engagement element is guided close to the foot part so that the risk of tripping due to protruding or protruding components is prevented. It is also preferred that the engagement element is adapted to the requirements that result from the structure on which the support post is to be braced.
  • the engagement element is preferably designed such that it can enclose one or more bars of the grating.
  • a design of the engagement element is particularly preferred in which the lower end of the engagement element is designed as a U-shaped hook which is suitable for encompassing one or more bars of the grating from below.

  • the tensioning means is designed as a lever which, in the tensioned state, rests essentially parallel on the foot part.

While the foot parts must follow a certain orientation depending on the structure, for example using the bars of gratings, the rotatability of the support tube also allows the balustrade to be oriented with any angular offset to the orientation due to the structure. This enables flexible and versatile use of the support posts and the quick-release railing in a modular design.

  • the lower end of the tube formed the foot part 3, which is thus integral with the support tube 1 was connected.
  • three rings each with a height of 20 mm and an outer diameter of 60 mm, were fastened with screws to the support tube 1 as fastening means 2 for upper Ge country braces .
  • the vertical distances between the three rings were each 60 mm.
  • the support tube 1 was placed with its foot part 3 vertically on a base plate 4 and welded to this.
  • a trapezoidal sheet metal was welded to the foot part 3 and to the base plate 4 on two opposite sides.
  • the base plate 4 with the dimensions 360 ⁇ 360 ⁇ 10 mm had two elongated holes of 30 ⁇ 100 mm.

  • the lengths of the partial struts of the upper and lower handrail struts were chosen so that in the retracted state a length of 1800 mm and in the extended state of 2500 mm was achieved, each measured from claw center to claw center. These dimensions correspond to the minimum length and the maximum length between which the railing struts can be telescopically adjusted.
  • a star handle 12 was provided on the upper and lower railing struts.

Abstract

L'invention concerne un montant porteur comprenant un tube porteur (1), qui comporte au moins un moyen de fixation (2) pour une barre de balustrade, une partie de pied (3), qui est reliée au tube porteur (1) et est délimitée sur son extrémité inférieure par une plaque au sol (4), dont la face inférieure est prévue pour être placée sur un corps de construction pour fixer le montant porteur, ainsi qu'un dispositif de serrage, qui est relié à la partie de pied (3) et qui comprend un moyen de serrage (5) ainsi qu'un élément de prise (6). La plaque au sol (4) comporte au moins une ouverture. Le moyen de serrage (5) et l'élément de prise (6) coopèrent de telle manière que l'élément de prise peut être guidé à travers l'ouverture dans la plaque au sol sur une surface d'appui dans le corps de construction, et le moyen de serrage tire l'élément de prise dans une direction verticale vers le haut dans l'état serré de sorte que la face inférieure de la plaque au sol (4) est serrée contre le corps de construction. L'invention concerne par ailleurs une balustrade à serrage rapide présentant une structure modulaire, qui comprend au moins deux montants porteurs selon l'invention.
