Definitions
- the present invention relates to a column head for attachment to a formwork support for formwork of a ceiling. Furthermore, the present invention relates to a slab formwork system, which has such formwork supports, columns heads and corresponding slab formwork elements. Furthermore, the present invention relates to a method for stripping a ceiling, which is feasible using such a slab formwork system.
- drop head supports which are used to build a slab formwork. Ceiling formwork panels are supported on the drop head supports, or supports on which formwork panels are arranged.
- the use of a drop head support allows a so-called ceremonieschalen.
- Early shelling means that after unlocking the case head at least a part of the slab formwork panels or formwork panels is removed, with the drop head supports (formwork support with case head) remain set up to stabilize the ceiling until it has the required capacity.
- the remaining head support cause relatively high costs for the provision of material, since the drop head supports are complex compared to simply constructed formwork supports without drop head.
- the column head is designed for attachment to a formwork support, for the formwork of a ceiling by means of a plurality of slab formwork elements, which each have a scarf surface.
- the column head has a connection section for connecting the column head to a shank section of the formwork support.
- the support head further comprises two support portions which are suitable for supporting at least one pair of adjacent ceiling formwork elements of the plurality
- the columns gropf has an adjusting device for moving a first of the support sections in an arrangement in which on the first support portion, the auflagbare slab formwork element is auflagbar on at least one lower support point, which has a lower Auflagungs us than the Einschalungs Auflagerungsdorf. At the lower Auflagungsdorf the Trolagerungsddling the second support portion remains on the Einschallungs Auflagerungsiere.
- a column head which heads in the early shelling an efficient dismantling of the formwork supports and columns allowed together with the slab formwork elements to head to the desired solidification of the ceiling by inexpensive steel tubular supports without elaborate columns head support. Due to the inventive design of the support head dismantling can be done in an efficient manner so that no column-free zones arise, which are already too large for the burden of the weight of the ceiling. Excessive column-free zones could damage the concrete.
- the column head according to the invention therefore allows the early reuse of the column head in a further slab formwork, for example in a projectile.
- the number of required support heads can be reduced and costs for the provision of the support heads are lowered.
- drop head supports have been developed which, in addition to the contact surface for the formwork, also have a further contact surface for the concrete of the ceiling.
- the contact surface for the formwork was designed so that it can be lowered to remove the formwork.
- These known drop head supports are constructed such that the concrete head on the one hand with the formwork, on the other hand, but also with the support surface of the case passes directly or via a cover strip in contact. If the concrete comes in contact with different materials, this can lead to undesirable traces in the surface of the finished concrete pavement.
- the props invention allows gropf that the contact of the formwork support with the ceiling takes place only on the slab formwork elements, since it is no longer necessary that the formwork support remains standing with the strut head after the Vietnameseschalen to support the ceiling. This reduces the risk of creating undesirable marks or marks on the surface of the concrete pavement.
- the slab formwork elements can be designed as slab formwork panels.

- sliding block 90 (I) fixed in the second support portion 34 is fixed.
- a pawl 98 is positioned in a pivot bearing 96 of the second support portion 34. The pawl 98 is located in a in Fig.
- first support portion 32 occupies a first storage position 102, in which the Auflagungstician Pi lies on the Einschalungs- Auflagerungsdorf u.
- the sliding block 90 (I) is located at the lower end 104 of the slot 92.
- the first support portion 32 integrally formed and connected via the adjusting device 46 with the second support portion 34.
- Fig. 7 is a longitudinal section through the support head 20 (I) in the fourth embodiment after lowering the first support portion 32 compared to the second support portion 34 by pivoting the first support portion 32 after releasing the locking device 56 is shown.
- the pawl 98 remains in the first end position 100.
- the sliding block 90 ⁇ I) is still located at the lower end 104 of the slot 92.
- the support surface 36 has an oblique orientation as compared to the vertical direction.
- FIG. 8 shows a longitudinal section through the column head 20 (I) in the fourth embodiment, wherein the first support section 32 occupies a second storage position 106.
- the first support portion 32 is located on the dissolved Locking device 56 on.
- the support surface 36 of the first support portion 32 is aligned parallel to the support surface 38 of the second support portion 34.
