Definitions

  • the invention relates to a formwork element for closing a gap in a ceiling formwork with a plurality of standard formwork elements which have a closed frame, the formwork element having a frame for supporting a formwork skin in a formwork skin plane.
  • the invention also relates to ceiling formwork with such a formwork element and a method for erecting ceiling formwork.
  • the slab formwork is composed of several standard formwork elements. These standard formwork elements typically have an all-round closed frame parallel to the formlining plane. Due to their flexibility, standard formwork elements in the form of frame panel formwork elements are preferably used.
  • a disadvantage of the known standard formwork elements is that in the event of an obstacle in the ceiling formwork, for example in the form of a Column, makeshift structures must be used to switch the obstacle.
  • FR 3 003 285 describes a formwork shell that is used for pouring concrete slabs into a trapezoidal zone.
  • the shelf consists of a fixed part, an expandable part and two intermediate bars.
  • the fixed part consists of a spar, two side bars made of intermediate crossbeams and the closing plate.
  • the expandable section consists of an expandable spar and two crossbeams articulated at joints. These two articulated sleepers slide in the side cross members of the fixed part.
  • A1 Grate ceiling formwork arrangement for integrating a column which comprises a) a frame, the frame comprising a base cross member, two parallel legs which are rotatably mounted on the base cross member, the axis of rotation (D) of the legs running parallel to the base cross member and the legs being perpendicular extend to the base cross member, an auxiliary cross member which is aligned parallel to the base cross member, the auxiliary cross member being slidably mounted on the legs and being lockable in various displacement positions, and b) at least one auxiliary leg which can be fastened in different fastening positions on the base cross member and on the auxiliary cross member, wherein the at least one auxiliary leg is aligned parallel to the legs in these fastening positions and is arranged between the legs.
