The invention relates to a large-area formwork consisting of several interconnected rectangular formwork elements consisting of a hollow body with a square or rectangular cross-section exist and movably connected to one another on the long sides and in the connected state are collapsible or stackable, and a method for stripping this large-area formwork, in the case of the massive components of the structure to be constructed to absorb the weight of the formwork during used for stripping.

A large-area formwork for walls made of several interconnected rectangular formwork elements, which can be movably connected to one another on the long sides and are in a connected state is collapsible or stackable, is based on the documents of the German utility model 1 868 848 known. The formwork bodies are hollow bodies educated. If this known large-area formwork is used to produce ceilings then the support structure is dismantled when stripping for this in the work process closely tied to the loosening of the individual formwork elements, i.e. the support structure can only be dismantled as far as the formwork elements are removed.

After completion of the respective concreting section, the rope strands made of steel or Plastic grouped formwork elements are hung on a crane and transported to the new site.

In terms of this prior art, the invention is based on the object of a large fairy form to improve the type mentioned in such a way that in the manufacture of ceilings Stripping process for the individual formwork elements regardless of the support structure this is feasible and that at the same time this stripping process is so simple in its course is that after loosening the individual Schalgheder the large-area formwork is automatic for the Transport collapses and stacks.

This object is achieved according to the invention that the connections of the formwork members are arranged so that the upper edges alternate or the lower edges of neighboring SchaluiursRlieder are interconnected, and that in each case the end link of the interconnected Formwork elements at a distance from its Sümlangsseite is provided with pulleys in the direction of the adjacent formwork member, which are supported by a striking mechanism are supported.

A method for stripping the large area shuttering in the case of the massive components of the structure to be constructed to take the weight of the formwork are used, is characterized in that the interconnected formworks on a stripping hanger consisting of at least two round rods ° or ropes, which in is anchored to the concreted components, lowered and collapsed into a stack.

The advantages achieved by the invention are that the large area formwork with little Expenditure of working time and manpower can be eliminated. The one given in the solution alternating arrangement of movable connections on the top and bottom of the formwork members enables automatic folding the formwork to a transportable stack, with the attached to the end Sdialui ^ members and pulleys running on the dismantling chain ensure that this stack is in the shortest possible time Time and by the shortest route from the center of the formwork surface.

An embodiment of the invention is shown in the drawing and is common in the following described with the method according to the invention. It doesn’t
