Definitions

  • the invention relates to a formwork panel having a frame which has a number of longitudinal struts and a number of transverse struts, the longitudinal struts and the transverse struts being arranged essentially perpendicularly to one another.
  • the invention also relates to a system for shuttering a wall element, comprising at least one shuttering panel.
  • the invention relates to the field of construction.
  • building parts are often formed by pouring concrete.
  • the shape of these cast building parts is specified by a formwork, the formwork being erected on the construction site before the casting.
  • ceilings or walls of a building are erected with the help of formwork.
  • scaffolding is required in order to be able to prepare the formwork for the construction of the wall element.
  • scaffolding is required to connect individual formwork panels to form the overall formwork, for example by attaching formwork locks.
  • two opposing formwork panels must be connected to one another by anchors before the production of a wall element in order to absorb the outward pressure of the poured concrete material.
  • the formwork panels must be accessible to workers over their entire height, which is usually done using scaffolding or a working platform.
  • reinforcement must be attached to an already positioned formwork or between such a formwork and a closing formwork which is opposite the formwork.
  • scaffolding or working platforms that are provided for attaching formwork locks are arranged on the formwork in such a way that no reinforcement can be attached to these scaffolding or working platforms.
  • the places where the reinforcement must be positioned are simply not accessible from these scaffolding or work platforms used to prepare the formwork panels, since they are on the opposite side of the formwork panel.
  • there are usually a large number of different types of scaffolding and formwork panels on the construction site which often means that the scaffolding cannot be connected to the formwork panels, in particular for the applications described above.
  • the object of the present invention is therefore to simplify the production of a wall element, in particular to enable flexible, universal and/or secure attachment of scaffolding, platforms and/or supports to formwork panels.
  • a formwork panel having a frame which has a plurality of longitudinal struts and a plurality of transverse struts, the longitudinal struts and the transverse struts being arranged essentially perpendicularly to one another, with at least some of the longitudinal struts and/or the transverse struts having at least two grooves running in the longitudinal direction and run on opposite side surfaces of the respective longitudinal strut and/or transverse strut.
  • the transverse and/or longitudinal struts (hereinafter collectively referred to as struts) have, geometrically speaking, two indentations on both sides, which serve as rails.
  • the profile of the depression has the shape of a bone.
  • a connecting component e.g. B. a clamping device are attached.
  • the connecting component which z. B. adapted to the profile includes gripping devices or grippers can be variably attached to the frame and removed. Scaffolding, platforms and/or supports, in particular push-pull supports, can thus be flexibly connected for aligning the formwork.
  • the grooves can be arranged axially symmetrically to one another and/or arranged opposite one another.
  • the grooves can have at least approximately the same shape.
  • the grooves can extend at least over part of the length or over the entire length of the respective longitudinal strut and/or transverse strut. It has turned out to be particularly suitable if the grooves extend over the entire length of the respective strut. As a result, connection components, for example clamping devices, can be fixed to the frame in a particularly advantageous and flexible manner.
  • the side surfaces of the respective longitudinal strut and/or transverse strut, in which the grooves are arranged, can run essentially perpendicularly to a front side of the frame provided for the attachment of a formwork skin.
  • the formwork panel can have a formwork skin which, when connected to the frame, rests on at least part of the longitudinal struts and/or the transverse struts, in particular on a front surface which is oriented forward and runs plane-parallel to the formwork skin.
  • the frame can have two outer frame transverse struts and two outer frame longitudinal struts, between which inner transverse struts and/or inner longitudinal struts are arranged, with preferably a part of the inner longitudinal struts and/or the inner transverse struts having the grooves.

  • the outer frame transverse struts and/or the outer frame longitudinal struts preferably have no grooves.

  • the grooves preferably run off-centre in the side surfaces in such a way that the grooves are at a greater distance from a front edge of the struts, in which the side surfaces converge with a front surface, than from a rear edge of the struts, in which the side surfaces converge with the rear surface. Due to the fact that the grooves run eccentrically in this way, a connecting component or a clamping device can be fixed in the grooves in a particularly advantageous manner. It is advantageous if the longitudinal struts and/or the transverse struts have holes in the side surfaces that are spaced apart from the grooves.
  • the holes are preferably made in a part of the side faces located between the grooves and the front edge.
  • the side walls of the respective grooves can be inclined outwards from a groove base of the respective grooves, in which case the side walls can preferably enclose an angle of 95° to 125°, in particular 110°, with the groove base.
