Definitions

  • the invention relates to a bearing head, as is used on a vertical support for supporting a ceiling formwork panel for concreting purposes.
  • the invention also relates to a ceiling formwork system made up of a ceiling formwork panel, a bearing head and a vertical support with a bracing element in combination.
  • Slab formwork systems are generally used in the construction of concrete slabs for buildings to create a receiving area for the flow concrete. After curing, this should form the desired ceiling structure.
  • ceiling formwork systems with formwork elements or panels mounted on vertical supports, it is problematic that horizontally directed forces can act on the vertical supports or the formwork elements, which can lead to the entire ceiling formwork system tilting and, in the worst case, even tipping over.
  • the concrete joist slab support assembly includes first and second slidable joists and first and second slab support frames.
  • the sliding crossbars adjust the width according to the size of the panels as they slide into each other.
  • the first and second panel support frames connect adjacent panels and support the first and second cross members.
  • the panel support frames include support panels and fasteners.
  • the support plate has support flanges, recesses and pin holes. The support flanges hold the plate. Support brackets touch the support plate when the sliding crossbars are inserted into the recesses of the support plates. From the KR 2012 0064657 A a slab formwork system is known in which vertical supports derive the load resulting from concreting a slab completely vertically.
  • a traverse is also used, which can be screwed to opposite sides of a surrounding panel frame for a ceiling formwork panel.
  • a mounting head sits on this traverse, to which a pull rod can be latched in order to be able to lower the ceiling formwork panel on the pull rod when stripping the formwork.
  • the object of the present invention is to improve a ceiling formwork system in order to be able to apply the greatest possible forces to a panel for dissipating horizontal loads with as little structural effort as possible.
  • the core idea of the invention is to collect horizontally occurring loads and divert them collectively.
  • the object is achieved in a ceiling formwork system according to claim 1 and a bearing head according to claim 9.
  • Advantageous embodiments emerge from the dependent claims.
  • a bearing head is designed with the invention, as can be used for a vertical support for supporting a ceiling formwork panel, but which, compared to the prior art, has a bracing traverse that is aligned transversely to the vertical support when mounted.
  • the length of the bracing traverse corresponds to at least one side length of the ceiling formwork panel to be supported.
  • the guying traverse can act with its respective ends on both side edges of the ceiling formwork panel, whereby the guying traverse acts simultaneously at two spaced points in order to support and brace the ceiling formwork panel.
  • the ceiling formwork system thus comprises at least one formwork panel, with at least one vertical support supporting the formwork panel, and with a bearing head described above and means for fixing the bracing element which are provided on the bearing head or sit on the bracing cross member.
  • the formwork panel has respective snap-in receptacles, so that when the bracing traverse is accommodated in the formwork panel, a tensile stress can be applied to the formwork panel by means of the bracing element via the traverse, in order to derive the load in the formwork plane at least partially horizontally.
  • the length of the bracing traverse of the bearing head is adapted to a side length of the formwork panel with regard to its length or its width.
  • the bracing traverse is accommodated in the center of the bearing head, wherein according to an advantageous embodiment the bracing element in the form of a chain or a belt, etc. acts equally centrally on the bracing traverse, so that the bearing head has the means for fixing the bracing element.
  • the bearing head can then be fixed via a flange on the vertical support and is carried by it.
  • the bearing head can have an alignment element in the form of a bolt which can protrude into a hollow end of the vertical support for alignment.
  • the formwork panel according to the bearing head according to the invention and in an advantageous embodiment of the ceiling formwork system according to the invention has a peripheral frame in which snap-in receptacles are provided as openings on opposite sides for receiving the ends of the traverse.
  • the opening mentioned is a snap-in receptacle in the form of an elongated hole, so that the bracing traverse is first inserted from below the formwork panel into a locking opening, then the guying traverse can be angled in a plane parallel to the formwork panel in order to introduce the second end of the guying traverse into the second locking receptacle opening.
  • the bracing traverse is braced, it is then brought into a stop position in the snap-in openings.
  • the guying traverse according to the bearing head according to the invention and in an advantageous embodiment of the ceiling formwork system according to the invention has two locking brackets projecting at right angles to the longitudinal axis of the traverse.
  • these are both provided at the same end of the guy beam at a distance from one another, so that a frame section of the formwork panel can be accommodated between them, with the shape and size of the external locking bracket being selected such that that it can only be passed through it in a specific position relative to the snap-in receptacle, which is complementary in shape and size.
  • the second locking bracket which strikes the inside of the frame section of the frame of the formwork panel, forms an inhibition of the translational displacement of the guying cross member along its longitudinal axis in the opposite direction.
  • the second, internal locking clip can be of any shape and size, since it does not have to be passed through the locking receptacle opening anyway.
  • the latching brackets are of identical design, being offset transversely to the longitudinal axis of the bracing cross member on the outer circumference thereof.
  • the bracing traverse can be pushed through one and the same latching receptacle opening with both latching brackets, given a suitable rotation about its longitudinal axis. This can facilitate insertion of the opposite end of the guy beam into the complementary snap-in opening. This applies all the more, the greater the length of the bracing traverse is relative to the relevant side length of the formwork panel.
  • the bearing head can be fixed to the vertical support by means of a flange.
  • the ceiling formwork system has a turnbuckle on the bracing element in order to build up and set a tensile stress through the bracing element between the anchoring point and the bearing head.
  • a formwork panel of the above type is configured in such a way that it can be coupled to other formwork panels via their end faces, it is possible to brace a plurality of formwork panels with a single bearing head and a bracing traverse connected thereto, so that the A bracing force applied via a bracing element of an individual formwork panel can be transferred to the formwork panels present in the direction of the force.
  • - 1 a perspective view of the bearing head according to the invention
  • - 2 a front view and top view of the bearing head 1
  • - 3 a respective perspective view from above and from below of the ceiling formwork system according to the invention
  • - 4 Details of the slab formwork system 3
  • - figure 5 Phases of mounting the bearing head on the formwork panel.
  • FIG. 1 shows the bearing head 14 according to the invention in a perspective view. It has a bracing traverse 16, the length of which roughly corresponds to the length of a side of a formwork panel 10, ie protrudes somewhat beyond it, in order to attach the ends of the bracing traverse to a frame 22 (see 4 ) of the panel to be fixed securely. Usually it is a peripheral frame of the panel.
  • the bracing traverse consists of a round tube which, for reasons of stability, is accommodated in a rectangular tube and fixed to it is connected, for example by welding.
  • the bracing traverse can also consist of a single rectangular tube frame or alternatively of a round tube, or that a round tube can be fixed, e.g. welded, to both sides of a central rectangular tube .
  • An element of the bearing head protrudes downwards transversely to the bracing traverse 16, namely a fastening support with which the bearing head 14 is mounted on a vertical support 12 (see Figures 3 and 4 ) can be placed and fixed via a flange 32.
  • the bracing traverse 16 can easily be rotated manually about its longitudinal axis (see details in the description of figure 5 ).
  • the alignment element 28 that can be seen below the flange serves to facilitate fixing of the bearing head in a hollow section of the vertical support.
  • bracing traverse 16 Also located on the bracing traverse 16 are means 20 for bracing the bearing head, which are also referred to, inter alia, as a bracing eye. These means, ie the guy eye, show two plate elements aligned parallel to one another and seated on the square tube frame, which are connected by a bolt.
  • the bracing element 18 (see, for example, 3 or 4 ) to be mounted.
  • the means 20, or rather the parallel plate elements can be rotated about the longitudinal axis of the guying traverse relative to the latter, so that any angle of the guying element 18 relative to the guying traverse can be assumed after it has been fixed to the bolt without the means 20 applying a torque to the square tube frame raise.
  • Two locking brackets 26 can be seen at one end of the bracing traverse 16, each of which has a stop in cooperation with the frame of the shuttering panel 10 (see, for example, 3 ) form in order to inhibit a translatory displacement of the bracing traverse 16 following assembly on the formwork panel (see details in the description of figures 4 and 5 ).
  • the bearing head 1 each in a front view and a plan view with the respective section AA.
  • the fastening support protrudes downwards at a right angle from the bracing traverse 16 , with the alignment element 28 protruding below the flange 32 .
  • the locking brackets 26 shown in the sectional view AA of the front view are shown in dashed lines because they lie in front of the sectional plane.
  • FIG. 3 shows the ceiling formwork system according to the invention from formwork panel 10 - to be more precise three formwork panels 10 are shown - a central formwork panel supporting vertical support 12 and a bearing head 14 with bracing traverse 16 in a mounted state in the middle formwork panel.
  • the anchoring element 18 can also be seen in the form of an anchoring chain. The latter is anchored to the ground by means of a fixing anchor (the ground is not shown in the drawing), and at the other end the anchoring chain is hung on the bolt of the anchoring means 20 .
  • a turnbuckle 30 is used to tension the guy chain 18 , with which the length of the guy chain can be varied, so that a guying force in the form of tensile stress can be applied to the bearing head 14 with guying traverse 16 .
  • a respective ceiling formwork element has a total of eight locking receptacles 24, ie two locking receptacles on each side length of the formwork panel. This allows a bracing traverse to each of the mount the short sides across the width of the shuttering panel, and a longer bracing traverse on the long sides of the panel.
  • each formwork panel can be braced in its width and/or in its longitudinal direction.
  • Said snap-in openings 24 are provided in the frame 22 of the formwork panel, which frame runs along the peripheral edge of the formwork panel. In 3 a bracing traverse is braced across the width of the middle formwork panel.
  • the bearing head 14 with the bracing traverse 16 is completely accommodated on the frame 22 of the formwork panel 10 and fixed by means of the locking brackets 26 in such a way that translational displacement of the bracing traverse 16 along its longitudinal axis in the surrounding frame 22 is inhibited.
  • the respective locking receptacle 24 is formed by a triangular slot opening. This facilitates the introduction of the bracing traverse 16 at the respective end.
  • the bracing traverse can be pivoted in a plane parallel to the formwork plane of the panel, with the dimensioning of the locking receiving opening 24 allowing the bracing traverse 16 to be easily pushed in from within the frame 22 as before.
  • Detail A clearly shows the stop of the outer locking clip 26 on the outer surface of the frame 22 of the shuttering panel 10.
  • phase 5 the phases 1-6 of an assembly of the bearing head with bracing traverse on the frame of a formwork panel are now shown.
  • the bearing head 14 is first tilted in order to align the outer snap-in clip about the longitudinal axis of the bracing cross member 16 in such a way that the outer snap-in clip 26 can be pushed through the relevant snap-in receiving opening 24 from the inside of the frame 22 (see also phases 2 and 3).
  • the bearing head 14 is then pivoted back down again, as a result of which the outer latching bracket 26 is also rotated in such a way that it can no longer be pushed back through the latching receptacle opening 24 .
  • the other, ie the inner locking clip forms a stop on the inside of the frame surface so that the bracing traverse 16 can no longer be displaced in a translatory manner along its longitudinal axis in the locking receiving opening 24 .
  • the bracing element 18 in the form of a bracing chain can then be hung on the means for bracing and a vertical support can be mounted on the bearing head via the flange connection 32 .
  • the guy chain can then be fixed and guyed there by means of a ground anchor, with the result that horizontal loads are transferred to the existing structure when the ceiling formwork panel is guyed.
