Definitions

  • the present invention relates to a prop head for attachment to a formwork prop for forming a ceiling. Furthermore, the present invention relates to a ceiling formwork system which has such formwork supports, support heads and corresponding ceiling formwork elements. Furthermore, the present invention relates to a method for stripping a ceiling, which can be carried out using such a ceiling formwork system.
  • drop head supports are known from practice, which are used for the construction of a ceiling formwork. Slab formwork panels are placed on the drophead supports, or girders on which formwork panels are arranged. The use of a drop headrest enables so-called early stripping. Early stripping means that after unlocking the drophead, at least a part of the slab formwork panels or formwork panels is removed, whereby the drophead supports (formwork prop with drophead) remain erected in order to stabilize the slab until it has the required load-bearing capacity. However, it has been shown that the remaining drop head supports cause comparatively high costs for the provision of material, since the drop head supports are complex compared to simply constructed formwork supports without a drop head.
  • WO 2012/174597 A1 discloses a prop head for attachment to a formwork prop.
  • the prop head is designed for attachment to a formwork prop, for forming a ceiling with the aid of a large number of ceiling formwork elements, each of which has a formwork surface.
  • the prop head has a connection section for connecting the prop head to a shank section of the formwork prop.
  • the support head also has two support sections, which are suitable for supporting at least one pair of adjacent floor formwork elements of the plurality of floor formwork elements, so that one of the floor formwork elements of the adjacent pair can be supported on at least one support point on each of the support sections.
  • the support points have essentially the same shuttering support height.
  • the support head has an adjustment device for moving a first of the support sections into an arrangement in which the floor formwork element that can be supported on the first support section can be supported on at least one lower-lying support point, which has a lower support height than the formwork support height. With the lower support height, the support point of the second support section remains at the shuttering support height.
  • dismantling can be carried out in an efficient manner in such a way that no support-free zones arise, which are already too large to bear the load of the ceiling's own weight. Excessively large column-free zones could damage the concrete.
  • the prop head according to the invention therefore allows the prop head to be used again at an early stage in another ceiling formwork, such as in a subsequent floor. As a result, the number of prop heads required can be reduced and costs for maintaining the prop heads can be lowered.
  • drop head supports were developed which, in addition to the support surface for the formwork, also have a further support surface for the concrete of the ceiling.
  • the support surface for the formwork was designed in such a way that it can be lowered to remove the formwork.
  • drophead supports are constructed in such a way that the concrete comes into contact with the formwork on the one hand and with the contact surface of the drophead on the other hand either directly or via a cover strip. If the concrete comes into contact with different materials, this can lead to unwanted marks on the surface of the finished concrete pavement.
  • the prop head according to the invention allows the formwork prop to contact the ceiling only via the ceiling formwork elements, since it is no longer necessary for the formwork prop to remain with the prop head after early stripping in order to support the ceiling. This reduces the risk of creating unwanted marks or imprints on the surface of the concrete pavement.
  • the ceiling formwork elements can be designed as ceiling formwork panels.
  • Each of the ceiling formwork panels can have a formwork surface and one or more carrier elements.
  • the carrier elements of the ceiling formwork panel can be crossbeams and/or longitudinal beams.
  • the side walls of the ceiling formwork elements can be understood as transverse and longitudinal beams.
  • the adjacent pair of ceiling formwork elements can be essentially identical.
  • the pair of adjacent ceiling formwork elements can adjoin one another with their transverse sides or with their longitudinal sides.
  • the adjacent pair of ceiling formwork elements can be aligned with one another and therefore form a common central axis.
  • Two pairs of slab formwork elements can be placed on the first and the second support section, with two slab formwork elements being placeable on the first support section and two slab formwork elements on the second support section.
  • Each of the support sections can each have a bearing surface on which the ceiling formwork element can be placed adjacently.
  • a section of a cross member and/or a section of a longitudinal member of the ceiling formwork element can be placed on the support surface.
  • the bearing surfaces may each be at the formwork bedding height.
  • the formwork support height and the reduced support height can refer to a position of use of the prop head.
  • the support sections can each have one or more engagement elements, such as hanging hooks.
  • the suspension hooks can each be open at the top.
  • the suspension hooks can be brought into engagement with a transverse and/or longitudinal beam of the ceiling formwork element.
  • the movement of the first support section can cause a change in a position and/or orientation of the first support section.
  • the second support section can remain in an unchanged position and/or orientation.
  • the second support section can be rigidly connected to the connection section.
  • the adjustment device is designed in such a way that the movement of the first support section results in a lowering of at least part of the first support section.
  • the adjustment device has a guide for the movement of the first support section.
  • the guide enables a controlled movement of the first support section into the arrangement in which the slab formwork element can be supported on the lower-lying support point.
  • the guide can be designed, for example, as a sliding guide or as a rotary guide and sliding guide.
  • the displacement guide can be designed to form a straight or curved guideway.
  • the displacement guide is designed as a slotted guide or linear guide and slotted guide. At least part of the movement may have a directional component directed towards a floor formwork element, the floor formwork element being supported on the first support section. This can facilitate the release of the slab formwork element from engagement with the first support section.
  • the pivot guide defines an axis of rotation which is located lower than the casing support height.
  • the guide is designed as a linear guide and as a link guide.
  • the guide can be designed as a rotary sliding guide with a slot for lowering the first support section in the vertical direction.
  • a slot allows both a pivoting of the first support section and a rectilinear lowering in the vertical direction.
  • the ceiling formwork element concerned continues to lie flat on the first support section. The lowered slab formwork element is still held securely in the prop head in this lowered position.
  • the elongated hole may be formed at an end of the first support portion. This allows the first support section to be pivoted with an elongate pivot arm.
  • a further embodiment of the support head is characterized in that a pawl is arranged in a pivot bearing of the support head.
  • the pawl rests in a first end position on the end of the first support section with the elongated hole when the first support section occupies a first storage position in which the support point of the first support section is at the shuttering support height.
  • the locking pawl falls automatically into a second end position, by means of which a second storage position of the first support section is fixed in place.
  • the pawl can slide into the second end position in a rotational movement at the end of the first support section with the elongated hole along the outer contour of the first support section.
  • the pawl prevents the first support section from being displaced upwards in the vertical direction.
  • the pivot bearing can have bulges and/or inwardly curved stops, not just a circular reach-through opening. Then the pawl can form a locking angle in relation to the vertical direction in the second end position. Below the locking angle of a canting of the pawl in the pivot bearing, the pawl can no longer be rotated back into its first end position by moving the first support section in the vertical direction and blocks displacement of the first support section in the vertical direction.
  • the pawl can have a reach-through opening.
  • the pawl can be unlocked manually via the reach-through opening. After unlocking, the first support section can be moved back up in the vertical direction.
  • the adjustment device has a releasable locking device.
  • the releasable locking device can releasably lock the movement of the first support portion.
  • the locking device can be designed in such a way that it can be actuated when the prop head is in a position of use and when all ceiling formwork elements that can be placed on the prop head are supported.
  • the locking device can have a wedge lock, for example.
  • other configurations of the locking device are also conceivable.
  • the slab formwork system has a large number of formwork supports.
  • the formwork props are each connected to a prop head according to one of the preceding embodiments.
  • the ceiling formwork system also has the multiplicity of ceiling formwork elements.
  • a ceiling formwork surface can be formed by resting the ceiling formwork elements on the first and second support sections of the prop heads, which covers the formwork props horizontally in a closed manner.
  • the support head has a moment support.
  • the moment support can be designed to engage with one of the ceiling formwork elements when this is supported on the second support section.
  • the moment support can be designed to support a torque which is exerted on the support head by a vertical load of the slab formwork element supported on the second support section.
  • the moment support can act on a surface profile, in particular on a crossbeam or longitudinal beam of the ceiling formwork element.
