  • scaffolding is required in order to be able to prepare the formwork for the manufacture 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 means of anchors in order to absorb the outward pressure of the cast-in concrete material.
  • the formwork panels must be accessible to workers over their entire height, which is usually done using scaffolding or a working platform.

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.
  • scaffolding or a work platform is required again after the actual casting in order to be able to carry out the final work.
  • a large number of different scaffolding or work platforms are therefore required for the production of a wall element using formwork, which leads to complicated work processes and the need for a large number of different scaffolding elements.

  • the formwork panel and the scaffolding section can be connected to one another in a simple manner by the connecting component, with the connection and also the disconnection of this connection being able to be carried out easily and quickly.
  • a system according to the invention usually comprises several formwork panels and can also comprise more than one scaffolding section.
  • a plurality of connecting components are usually provided for the connection, which are arranged at different positions between the formwork panel or formwork panels and the scaffolding section.
  • the scaffolding section of the system according to the invention is formed by a scaffolding section according to the prior art and comprises several vertical standards which are essentially vertically oriented in the assembled state and several horizontal bars which are essentially horizontally oriented in the assembled state. These elements of the framework section are connected to one another and, when assembled, form a framework section extending in three spatial directions.
  • the truss section may include other elements such as treads, ladders, railings and the like.
  • the skeleton section is preferably constructed in a modular manner, which means that the skeleton section can be constructed from standard elements of different sizes and shapes.

  • the formwork skin is fastened to the frame and rests on at least part of the longitudinal struts and transverse struts.
  • an undercut is to be understood as meaning an area which is set back in relation to neighboring areas. If a counter-element is connected to the frame of the formwork panel in such a way that it engages in the undercut in some areas, a form fit is created, by which the counter-element is connected to the frame.

  • the undercut extends in the longitudinal direction of the longitudinal struts and/or transverse struts.
  • the undercut can be formed by a groove which is set back from the remaining surface of the longitudinal struts and/or transverse struts and which extends along these struts.
  • This extension of the undercut in the longitudinal direction means that a connecting component can be fastened steplessly at different positions on the frame of the formlining.
  • This variability in the location of a connecting member to the frame can be connected means that formwork panels and scaffolding sections with different grids can be connected to one another very easily.
  • the system according to the invention also includes at least one connection component with a framework interface and a formwork interface.
  • the formwork interface is intended for connection to the formwork panel, in particular to the frame of the formwork panel.

  • the clamping element can have other elements, for example a mechanism for actuating and locking the gripping arms.
  • the connection between the connecting component and the frame of the formwork panel is established in that the two gripping arms are initially adjusted in such a way that they can partially grip a transverse strut or a longitudinal strut of the frame.

The distance between the two gripping arms is then reduced, with these engaging at least in certain areas in the undercut on the frame.
  • a non-positive connection in particular a clamp, is preferably produced at the same time between the gripping arms and the frame.
  • a non-positive connection ensures that there is no play between the connecting component and the formwork panel and thus a stable, statically and dynamically loadable connection is created.
  • What is particularly advantageous about this connection is that it can be produced at different positions in the longitudinal direction of the transverse strut or the longitudinal strut.
  • the connecting component can be variably positioned relative to the frame of the formwork panel.
  • the undercut advantageously extends over the entire free length of the transverse struts and the longitudinal struts.
  • connection can be made to the connecting component at almost all locations on the frame of the formwork panel.

  • the scaffold section supports the formwork panel and vice versa.
  • the scaffolding section positions the formwork panel, for example within a formwork or a formwork system for the production of a wall element.
  • the system is designed in such a way that it can preferably be used without additional support elements, such as supports.
  • the system according to the invention thus avoids the expense of attaching additional support elements for setting up and positioning the formwork panel.
  • the connection of the formwork panel and scaffolding section using the connecting component also makes it possible to transport and position the entire system together.
  • the built-up system can be positioned with the help of a crane at the point where it is needed for the production of the wall element. This eliminates the need to set up the system at the location where the wall element is to be created.
