Abstract

A support head for attachment to a formwork support for creating the formwork for a floor using a large number of floor formwork elements which each have a form surface. The support head has two support portions suitable for supporting at least one pair of adjacent floor formwork elements of the large number of floor formwork elements. The support head has an adjustment device for moving a first support portion into an arrangement in which the floor formwork element which can be mounted on the first support portion can be mounted thereon on at least one subjacent mounting point which is at a lower mounting height than a formwork mounting height. The mounting point of the second support portion remains at the formwork mounting height.

First claim

The invention claimed is:

1. A support head for attachment to a formwork support for creating the formwork for a floor using a plurality of floor formwork elements which each have a form surface; wherein the support head has:
a connecting portion for connecting the support head to a shaft portion of the formwork support;
two support portions configured for supporting at least one pair of adjacent floor formwork elements of the plurality of floor formwork elements such that each one of the floor formwork elements of the adjacent pair can be mounted on each of the support portions on at least one mounting point;
wherein the mounting points have a substantially equal formwork mounting height;
wherein the support head has an adjustment device for moving a first support portion into an arrangement in which the floor formwork element which can be mounted on the first support portion can be mounted thereon on at least one subjacent mounting point which is at a lower mounting height than the formwork mounting height, wherein the adjustment device has a sliding guide for the movement of the first support portion, wherein the sliding guide is designed as a slotted guide and forms a straight or curved guide track;
wherein at the lower mounting height, the mounting point of the second support portion remains at the formwork mounting height,
wherein the first support portion pivots relative to the second support portion such that at least part of the movement has a direction component which is oriented toward a floor formwork element, the floor formwork element being mounted on the first support portion.

2. The support head of claim 1 , wherein the slotted guide includes slotted links and slotted-link blocks, the slotted links being arranged so as to be moveable relative to the rigidly arranged slotted-link blocks.

3. The support head of claim 1 , wherein the sliding guide is designed to form the curved guide track, wherein the slotted guide includes slotted links and slotted-link blocks, the slotted links being arranged so as to be moveable relative to the rigidly arranged slotted-link blocks.

4. The support head according to claim 1 , wherein the adjustment device is configured such that at least one part of the first support portion is lowered by the movement of the first support portion.

5. The support head according to claim 1 , wherein the adjustment device has a releasable locking device which releasably locks the movement of the first support portion.

6. The support head of claim 1 , wherein the first support portion pivots relative to the second support portion about an axis of rotation arranged at a height lower than the formwork mounting height.

7. A system, comprising:
a formwork floor element; and
the support head of claim 1 .
