BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention concerns a system ceiling form with ceiling supports and rectangular form components as well as ceiling carriers, whereby vertically standing sections are provided for on a support head containing a head plate which lie in a perpendicular plane containing the support axis and are arranged at a separation from the perpendicular support axis.
In ceiling supports of this kind known in the art through EP 297 357 B 1, a rectangular head plate exhibits arms which extend radially beyond the edges of this plate at the ends of which perpendicular bolts are attached which can engage into the edge regions of a frame of a form component supported on the plate to secure these form components. The four edges of the form components seated on the head plate meet at the extension of the support axis. Radially running raised rods are provided for on the side surfaces of the head plate which seat on the side surfaces of the mutually adjacent form components. The corner of a form component is secured by means of the bolts and the struts.
In the event that the support is to be lowered, removal of the form components between the retracted head plate and the lower surface of the concrete ceiling is difficult, since the corners of the form components are captured between the bolt and the struts and therefore the form components, due to their thickness, prohibit a pivoting motion about an axis running diagonally between the edges. The form components must therefore be raised by the complete height of the bolt in the upper direction when disassembling. This support head is only suitable for the seating of form components and not for the seating of ceiling carriers.
It is therefore the underlying purpose of the invention to develop ceiling forms which are extremely safe in particular when disassembling the ceiling components and nevertheless are easy to handle and whose support heads, while exhibiting a high degree of safety, allow for a simplification of the ceiling form and are suitable for the seating of various components of a ceiling form.
SUMMARY OF THE INVENTION
This purpose is achieved in accordance with the invention in that that the plate sections, as holding means for the ceiling components supported on the support head, engage into the under side of the ceiling components and an additional abutment is provided for the ceiling components above which the ceiling component must be raised following pivoting when disassembling.
This form has the advantage that the ceiling form components, when pivoting, do not unintentionally travel above the abutment or the upper end of this holding means and do not thereby fall down. Following pivoting, it is necessary for the ceiling components to only be raised by a small degree in order to completely remove them from the support. With the introduction of further components ceiling carriers as well as form components can be securely seated on a support head of this type.
For example, form elements can be seated on the ceiling carrier. This form therefore has a plurality of applications.
In embodiments of the invention the plate sections exhibit a front surface facing the support axis which travels in the upper direction in such a fashion that the plate section tapers upwardly, whereby a perpendicular or undercut front surface section forms an adjacent abutment at the upper end of the front surface.
This form has the advantage that the feet of frames of form components are displaced upwardly onto the diagonal surface formed by the tapering during pivoting. In this fashion the stop prevents the ceiling form components from unintentionally travelling over the upper end of this holding means during pivoting to fall down. Following pivoting, it is only necessary to lift the form elements by the small amount corresponding to the height of the stop in order to completely remove them from the support.
When pivoting out, the form components are pivoted about a pivot axis at their foot at the edge. A further advantage of this embodiment is, during disas
