  • This disclosure also relates to the modular pod itself.

  • the modular pod finds particular application in multi-storey constructions but is not limited to the forming of a stairwell for a stairway.
  • the modular pod may provide permanent formwork suitable for the forming of a lift well, a shaft or another similar structure within a building.
  • the method of constructing the modular pod as disclosed herein comprises arranging a base frame for the pod.

Abstract

L'invention concerne une nacelle modulaire et son procédé de construction, appropriés pour une utilisation en tant que coffrage permanent. La nacelle comprend un châssis de base et le procédé comprend l'agencement du châssis de base. La nacelle comprend également au moins un support individuellement raccordé pour s'étendre vers le haut à partir du châssis de base et le procédé comprend l'agencement des supports pour s'étendre à partir du châssis de base. La nacelle comprend en outre au moins un module de coffrage, une base de chaque module étant agencée au niveau du châssis de base, chaque module de coffrage s'étendant vers le haut à partir du châssis de base et le procédé comprenant l'agencement des modules au niveau du châssis de base. La nacelle comprend, de plus, un châssis supérieur, le châssis supérieur étant raccordé vis-à-vis de l'au moins un support et agencé de sorte qu'une partie supérieure de chaque module de coffrage s'étende jusqu'au châssis supérieur lors de l'utilisation et le procédé comprend l'agencement du châssis supérieur sur chaque module de coffrage.
