Definitions

  • the invention relates to a slab formwork with a formwork plate at its upper end supports, the supports connecting beams and between the beams with these flush-mounted formwork panels, the edges of which bear against the edges of the beams in the use position, the supports also when shuttering and stripping have fixed, non-adjustable support head with a fastening device arranged under its formwork panel for attacking the formwork girders by means of a detachably connectable flange or fastening attachment.
  • Such slab formwork is known from DE-C-3003682.
  • the ends of the supports each have a flange which engages under the underside of the fastening device of the support head and can be releasably connected to it, so that the connecting means, preferably connecting bolts, must be inserted vertically through this flange from below.
  • the connecting bolt itself is only subjected to tension, the use of such connecting bolts with transverse pins, which are inserted through keyhole-like perforations, results in a load of the transverse pins on shear in the rotated position.
  • tension in the perforations which are penetrated at the same time can prevent the bolt from being easily pulled out, although these bolts are rotatable.
  • the solution to this problem consists essentially in that the support head on at least one side and the support only on that side of the support head facing side have a hook-in connection with which the carrier is pivotally attached to the support and guided by the hook-in connection in its use - And the fastening position can be swiveled up, in which the end of the carrier opposite the hook-in connection has an anchoring fastening device with its flange with the next support head.
  • DE-C-2311544 already discloses a suspension connection between the support head and the support for a support device for formwork beams of a ceiling formwork of another type.
  • this hook-in connection is provided at both ends of the carrier as a single attachment and a groove lying on a concentric circle is necessary on the support head and a corresponding projection on the carrier for engaging in this groove, which due to manufacturing tolerances leads to inaccuracies in the alignment of the wearer through lateral play against the support head.
  • the carrier is only securely attached to the support head when the entire formwork composite has been produced, i. H. During stripping and later when stripping formwork panels, beams are exposed, which then only lie loosely in their hanging grooves.
  • a slab formwork system of another type in which the beam is coupled to a support head via a hanging connection, but the support head is adjustable in height so that after hanging the support head with the support is moved upwards in the position of use and is moved down again for stripping.
  • hook-in connections that is to say not at least one fastening flange in accordance with the solution according to the invention, are provided at both ends of the carrier and in corresponding locations on the support heads.
  • a particularly secure and precise fixing of the support is obtained if the support and the support head have a flange connection which can be locked in the position of use of the support, even in the region of their suspension connection.
  • the hook-in connection then serves above all for easy striking and stripping of the beam, because the beam can initially be temporarily fixed on one side, then locked on the opposite side and finally locked in the area of the hook-in connection. In Ge then the forces are absorbed by the flange connections.
  • the support head can have a hanging device for a swivel connection on its two opposite connection end faces for supports. This has the advantage that the user does not have to pay attention to whether the respective support head with its hooking device is correctly oriented, since a rotated position by 180 ° also fits a corresponding carrier.
  • An embodiment of the invention of considerable importance which above all makes it easier to remove formwork even with somewhat jammed fastening bolts, can consist in that the flanges on the support head and support run in cross-section from top to bottom. This gives the fastening bolts an approximately parallel or only slightly oblique orientation to the formlining, so that their ends can be acted upon by a striking tool should a bolt ever become jammed. This arrangement is therefore of greater importance for the simplification of the formwork work.
  • the fastening or locking bolts themselves are subjected to shear in such a locking, the bolts themselves being able to absorb greater shear forces than their transverse pins.
  • a very special embodiment of the ceiling formwork of the type mentioned at the outset can consist in that the fastening flange of the support head, starting from its formwork plate, is inclined obliquely towards the support and the corresponding front flange of the support has a corresponding bevel, the flanges of the support head lying opposite one another are arranged closer to each other with their lower edges than with their upper edges.
  • the connecting bolts are given a slightly oblique course, which does not impair the simplicity of the stripping process and furthermore enables the use of an impact tool, but makes insertion a little more convenient from the bottom up.
  • Embodiments of the invention in particular with regard to the suspension connection, are the subject of claims 5 to 16.
  • a ceiling formwork results in which the advantages of the ceiling formwork according to DE-C-3003682 are largely retained, but the additional formwork means that the formwork is removed and removed Hanging connection can be carried out by a single person.
  • the second person who has to hold the girder with the known slab formwork, is practically replaced by the hanging connection. Nevertheless, the risk of accidents is also reduced because the hook-in connection can be designed accordingly safely and mutual consideration of two operators is avoided.
  • a ceiling formwork designated as a whole has supports 2 which have a formwork panel 3 at their upper end.
  • the support 2 in the exemplary embodiment has a support head, generally designated 4, which on its underside below its formwork plate 3 has a plug-in attachment 5 for coupling with the actual support 2, as is indicated in FIG.
  • the slab formwork 1 also includes the supports 2 with the support heads 4 connecting supports 6 and also between the supports 6, which can be fastened in alignment with them and not shown in the drawing, the edges of which rest against the edges or edge webs 7 of the support 6 in the use position.
  • the support head 4 has fastening devices for attacking the formwork girders, which in turn has releasably connectable flanges 8 'as a fastening attachment.
  • the fastening bolts 9 used to connect the flanges can run largely horizontally or in any case in such a way that their end faces opposite to their bolt heads 10 remain accessible for a striking tool, which makes stripping easier, even if a bolt 9 should be jammed inside the connection perforations 11.
  • the support head 4 and the support 6 have a suspension connection 12 with one another on a facing end face, the individual parts of which can be seen in FIGS. 1 to 3 and whose interaction can be seen in FIG. 4.
  • the support 6 can be pivotally fixed at least temporarily on the support 2 or the support head 4.
  • This suspension connection 12 also allows the support to be swiveled up into the use and fastening position shown in FIG. 4, the suspension connection 12 guiding the support so that it is in the desired aligned position in relation to the next support 2 and the support head 4 arrives.
  • the end of the carrier opposite the hook-in connection 12 can be connected with its flange 8 ′ to the next support head 4.
  • the support 6 and the support head 4 also have a flange connection which can be locked in the position of use of the support 6 by means of bolts 9 in the region of their suspension connection 12.
  • the support head 4 has on each of its two opposite connection end faces for support 6 a suspension device to be described for the hook connection 12.
  • a holding bolt 13 running transversely to the pivoting direction and the orientation of the support 6 and on the counterpart a matching hook 14 serving to overlap the holding bolt 13, the hook opening of which according to FIG. 4 and also according to FIGS 2 and 3 points essentially downwards.
  • the pivot axis 15 of the hook-in connection 12 is located below the flange connection and its locking attachment, as shown in FIG. 4, approximately at the level of the lower edge 8a of the flange 8. This makes it easily possible to mount a bracket 6 on its hook-in connection 12 after loosening the flange connections to pivot downward, whereby the flanges 8 and 8 'in the region of the hook-in connection 12 also detach from one another.
  • the support head 4 can also be used very close to a wall without protruding hooks protruding from it.
  • the one or more retaining bolts 13 of the hook-in connection is arranged below the outline of the formwork panel 3 of the support head 4.
  • the flange 8 of the support head 4 has recesses 16 in its area higher than the one or the retaining bolts 13, in the exemplary embodiment slots for inserting the hooks 14.
  • the flange 8 of the support head 4 has two slots 16 for the passage of these hooks 14.
  • At least one continuous retaining bolt 13 running parallel to the plane of the fastening flange 8 could be provided on the support head 4.
  • the flange 8 of the support head 4 is inclined somewhat obliquely towards the support.
  • the corresponding frontal flange 8 'of the carrier 6 has a corresponding inclination or inclination, the flanges 8 of the support head 4 lying opposite one another being arranged closer to one another with their lower wheels 8a than with their upper edges in the area of their formwork panel 3. This gives the frontal sides Flanges 8 'of the carrier 6 already from the outset the inclination which they would also receive when swiveling downward about the hook-in connection 12 and which, in the inclined position provided, only needs to be increased in the use position.
  • the hooks 14 of the hook-in connection 12 are arranged directly on the inner sides of the side webs 18 of the carrier 6 and that accordingly the hook-in slots 16 are also provided in the end flanges 8 directly next to the side walls 17 of the support head 4 are.
  • the bolts 13 are least stressed on bending.
  • the carrier 6 can have a part 19 which can be pulled out in its longitudinal direction, the hooks 14 in this case being arranged on the guide body 20 of the carrier holding the pull-out part 19.
  • the user can first hang this extendable carrier 6 on a support head 4 and then pull out the extendable part 19 to the required length up to the next support head 4 and fasten it there.
  • a box-shaped extension 23 with an end flange 8 ' is provided on the extendable part 19 of the telescopically extendable carrier 6 in the region of an end piece 22 which closes the guide tube 21 of this extendable part 19 and which has the end flange 8', which the fastening device, in the exemplary embodiment has keyhole-like perforations 11 for connection to the support head 4 and its flange 8 and is at a distance from the end face of the guide tube or tubes 21.
  • keyhole-like perforations 11 and cross pins having fastening bolts 9 are provided for connecting the flanges 8 and 8 'and for locking them as fastening points, which are indicated in FIG. 4.
