The mounting head has an anchoring cross-member which in the mounted state on the vertical support is oriented transverse thereto, the length of the anchoring cross-member corresponding to at least one side length of the ceiling formwork panel to be supported, whereby the anchoring cross-member is respectively affixable at its ends to lateral edges of the ceiling formwork panel.

Claims

Description

[0021] Additional details and further advantages of the invention are described below on the basis of an embodiment, which, however, should not be read as a limitation of the present invention; the same applies with regard to the accompanying drawing figures.

[0022] Shown in the drawing figures are:

[0023] FIG. 1 a perspective view of the mounting head according to the invention;

[0024] FIG. 2 a front view and a top view of the mounting head from FIG. 1:

[0025] FIG. 3 a relative perspective view from above and from below of the ceiling formwork system according to the invention;

[0026] FIG. 4 Details of the ceiling formwork system from FIG. 3; and

[0027] FIG. 5 Phases of an assembly of the mounting head on the formwork panel.

[0028] FIG. 1 shows the bearing head 14 according to the invention in perspective view. It has an anchoring cross-member 16, the length of which roughly corresponds to a side length of a formwork panel 10, i.e. projects somewhat past it in order to securely affix the ends of the anchoring cross-member to a frame 22 (see FIG. 4) of the panel. Normally, this is a perimeter frame of the panel.

[0029] In the present case, the anchoring cross-member is made of a round pipe, which for stability reasons is accommodated within a rectangular pipe and is solidly connected thereto, for example via welding. As a result, the anchoring cross-member has an optimal connection rigidity. This represents one embodiment. Of course, one skilled in the art understands that the anchoring cross-member can generally be made of a single rectangular pipe frame or, alternatively, a round pipe, or that a round pipe may be affixed, e.g. welded on, on both sides at a central rectangular pipe.

[0030] Transverse to the anchoring cross-member 16, an element of the mounting head projects downward, namely a mounting bracket, with which the mounting head 14 is placeable on a vertical support 12 (see FIGS. 3 and 4) and is fixable via a flange 32. By means of the mounting bracket and an alignment element 28, the anchoring cross-member 16 can easily be turned manually about its longitudinal axis (see the description for FIG. 5 for more details on this), The alignment element 28, which is recognizable below the flange, is used to facilitate affixing the mounting head within a hollow section of the vertical support.

[0031] Furthermore; means 20 for anchoring the mounting head, which are also referred to as, among other things, an anchoring eye, sit on the anchoring cross-member 16. These means, i.e. the anchoring eye, show two parallel plate elements that sit on the rectangular pipe frame and are connected by a pin. The anchoring element 18 (see, for example; FIG. 3 or 4) can be hooked in on this pin. The means 20 or, better put, the parallel plate elements can be turned about the longitudinal axis of the anchoring cross-member relative thereto, so that any angle of the anchoring element 18 relative to the anchoring cross-member can then be assumed for a fixation on the pin without the means 20 applying a torque to the rectangular pipe frame.

[0032] Two latching clips 26 are recognizable at one end of the anchoring cross-member 16, and each form an abutment in interaction with the frame of the formwork panel 10 (see e.g. FIG. 3) in order to inhibit a translational displacement of the anchoring cross-member 16 following a mounting on the formwork panel (see details about this in the description related to FIGS. 4 and 5).

[0033] FIG. 2 shows the mounting head from FIG. 1 in a front view and a top view with respective section A-A. As can be recognized in the front view, the mounting bracket projects at a right angle downward from the anchoring cross-member 16, the alignment element 28 projecting below the flange 32. The latching clips 26 shown in the sectional view A-A of the front view are illustrated with broken lines because they are in front of the sectional plane.

[0034] FIG. 3 shows the ceiling formwork system according to the invention from formwork panel 10more precisely, three formwork panels 10a vertical support 12 supporting the central formwork panel and a mounting head 14 with anchoring cross-member 16 in a state of being mounted in the central formwork panel. The anchoring element 18 in the form of anchoring element can also be recognized. The latter is anchored on the ground by means of a fixation anchor (the ground is not illustrated in the drawing), and at the other end the anchoring chain is hooked in on the pin of the anchoring means 20. To tension the anchoring chain 18, a turnbuckle 30 is inserted therein with which the length of the anchoring chain can be varied, so that a tensioning force in the form of tensile stress can be applied to the mounting head 14 with anchoring cross-member 16.

[0035] A respective ceiling formwork element has a total of eight latching recesses 24, i.e. two latching recesses on each side length of the formwork panel. As a result, an anchoring cross-member can be installed on each of the short sides over the width direction of the formwork panel, and a longer anchoring cross-member on the long sides of the panel. In other words, each formwork panel can be anchored in its width direction and/or in its longitudinal direction.

[0036] Said latching recess openings 24 are provided in the frame 22 of the formwork panel, which frame runs around the perimeter of the formwork panel. In FIG. 3 an anchoring cross-member is anchored over the width of the central formwork panel.

[0037] From FIG. 4, mounting details of the anchoring cross-member can be seen on the formwork panel, i.e. on its frame 22. As shown, the mounting head 14 with anchoring cross-member 16 is completely accommodated on the frame 22 of the formwork panel 10 and fixed via the latching clip 26 in such a way that a translational displacement of the anchoring cross-member 16 along its longitudinal axis in the perimeter frame 22 is inhibited. The respective latching recess 24 is formed by a triangular oblong hole. As a result the introduction of the anchoring cross-member 16 on the respective end is made easier. In other words, the anchoring cross-member can be swiveled in a plane parallel to the formwork plane of the panel, a pushing in of the anchoring cross-member 16 from within the frame 22 being easily possible as before thanks to the dimensioning of the latching recess opening 24.

[0038] The detail A shows very clearly the abutment of the outer latching clip 26 against the outer surface of the frame 22 of the formwork panel 10. With the aid of the configuration of the two latching clips 26 (see FIG. 1), it can be determined that the inner latching clip 26 abuts the inner side, i.e. the inner surface of the frame 22 and the anchoring cross-member 16 is held by this abutment in such a way that they cannot be displaced outward through the latching recess opening 24 shown in Detail A. As a result, the anchoring cross-member 16 overall also cannot be displaced through the opposite opening, as shown in Detail B.

[0039] In FIG. 5, the phases 1-6 of a mounting of the mounting head with anchoring cross-member on the frame of a formwork panel are shown. To align the outer latching clip, the mounting head 14 is first tilted about the longitudinal axis of the anchoring cross-member 16 in such a way that the outer latching clip 26 can be pushed from the inner side of the frame 22 through the latching recess opening 24 associated therewith (see also phases 2 and 3). In phase 4, the mounting head 14 is swung back down, whereby the outer latching clip 26 is co-rotated in such a way that it can no longer be pushed back through the latching recess opening 24. Moreover, the other one, i.e. the inner latching clip, forms an abutment on the inner side of the frame surface so that the anchoring cross-member 16 can no longer be translationally displaced within the latching recess opening 24 along its longitudinal axis.

[0040] Subsequently, the anchoring element 18 in the form of an anchoring element can be hooked in on the means for anchoring, and a vertical support can be mounted via the flange connection 32 on the mounting head. The anchoring chain can then be affixed and tensioned there by means of a ground anchor, whereby as a result horizontal loads on the existing structure are borne in the anchored state of the ceiling formwork panel.
