- Connection element for connecting a formwork support head with a pipe support
- the invention relates to a connecting element, preferably for connecting a formwork support head to a pipe support, comprising a base element which has an interface for connection to at least one further element, in particular to a formwork support head, and to a bracket and at least two bearing elements that connect the base element to the bracket .
- the bracket has a length which spans at least the distance between the bearing elements.
- at least two tensioning elements are provided which, in operative connection with the bearing elements, tension the bracket relative to the base element.
- the invention further relates to a connection system with a connection element and a pipe support, as well as a method for connecting a connection element to a pipe support.
- formwork support heads are directly connected to the formwork and are designed in such a way that the formwork can be lowered just enough from the hardened ceiling with a few simple movements to be able to easily remove it.
- the formwork support heads will be placed on extending elements so that they can be placed at ceiling height.
- Such lengthening elements can be pipe supports, for example.
- Such pipe supports are usually adjustable in length and thus adaptable to different room heights.
- Various solutions for connecting such pipe supports with formwork support heads are known from the prior art known.
- a very simple solution is to connect part of the pipe supports to the formwork support heads with screw connections. The disadvantage of this is that the attachment and removal of these screw connections is time-consuming.
- a solution is known from EP 3 121 349 A1 in which the formwork support heads are connected to the pipe supports via a clamping device operated by threaded bolts.
- This solution also requires the complex tightening of screw connections in order to establish a fixation between the formwork support heads and the pipe supports.
- this solution has a large number of sensitive components that quickly become dirty and wear out in the harsh ambient environment on the construction site, which means that they have to be replaced regularly.
- the object of the invention is thus to propose solutions with which a further element, for example a formwork support head, can be fixed in a simple manner to an elongating element, for example a pipe support, firmly and yet detachably.
- a further element for example a formwork support head

- the connecting element according to the invention is based on a base element on which further components of the connecting element are arranged.
- the base element has an interface for connection to a further element, in particular to a formwork support head.
- the interface can be designed in a simple manner as a connection surface to which the further element is welded.
- the further element can also be connected to the base element via various other connections, such as screw connections or bayonet connections.
- the connecting element according to the invention also has a bracket which is designed to be movable relative to the base element.
- This bracket is intended to provide, together with the base element, a clamping of at least part of a pipe support.
- the base element and bracket can be connected to one another via at least two bearing elements or are connected to one another in the assembled state.
- the bracket has at least one length that is greater than the distance between the two bearing elements.
- the bracket thus spans the two bearing elements.
- the bearing elements are usually arranged on the edges of the base element. In this case, the bracket also spans the base element.
- At least two tensioning elements are provided for clamping or tensioning at least a part of the pipe supports between the base element and the bracket. These clamping elements are in operative connection with the bearing elements.
- the bearing elements are also moved in such a way that the base element and bracket are moved towards one another.
- the bracket is tensioned in the direction of the base element, as a result of which at least part of the tubular support is releasably fixed to the connecting element in a non-positive and / or positive manner.
- the bracket is pivotably mounted on one of the two bearing elements. As a result, the bracket can be pivoted relative to the base element.
- the bracket can be moved away from the base element before a part of the pipe support is mounted on the connecting element, in order to facilitate the introduction of the pipe support. Subsequently, the pivotably mounted bracket is pivoted back to the base element and to the second bearing element in a simple manner, whereby a first, initially still loose form-fit is created between the two components. This form fit can be produced in a very simple manner without the aid of tools.
- the bracket In the pivoted-back state, the bracket is then still loosely connected to the base element via both bearing elements.

Due to the large area tension, the connection between the components is very stable. Furthermore, as a result of the tension over a large area, there is only very little wear and tear on the components of the connecting element according to the invention, as a result of which it is durable.

- the outer wedge-shaped areas of the tensioning elements rest on the inner surfaces of the receiving slots, whereby a linear movement of the tensioning elements parallel to the bearing surface causes a linear movement of the pressure surfaces of the tensioning elements in a linear movement directed essentially at right angles to the bearing surface.
- the tensioning elements are arranged in such a way that the wedge-shaped area rests on the side of the receiving slots facing away from the support surface.
- the pressure surfaces are also located inside the receiving slots and face in the direction of the support surface and in the direction of the mounted bracket. If the clamping elements are moved in a direction parallel to the receiving surface, the wedge-shaped area runs along one end of the receiving slots.
- the two alternative embodiments of a connecting element described are based on the same operating principle, using a wedge-shaped element to use a linear movement of a tensioning element into a linear movement directed at right angles to it to clamp at least part of a pipe support in the connecting element.
- the advantage of both embodiments is that a simple, linear movement of the tensioning elements is sufficient for relaxation.
- the connection of the connecting element to a pipe support is therefore simplified and accelerated.
- the proposed solutions are robust and very well suited for the environmental conditions on the construction site.
- the bracket which extends between two bearing elements arranged opposite one another and clamps part of the pipe supports flat.
- connection system with a connecting element according to one of the embodiments described above and a pipe support, the pipe support having a support area and at least one support head and the support head being designed in the form of a plate, the plate-shaped support head having a plate thickness, in which connected state of connecting element and pipe support, the end face of the support head facing away from the support area of the pipe support rests against the bearing surface of the connection element and the contact side of the bracket of the connection element rests against the surface of the support head facing the support area of the pipe support and the bracket is connected to both bearing elements, the Clamping elements clamp the support head between the base element and bracket by means of the bearing elements.
- a connection system comprises, in addition to a connection element according to one of the embodiments described above, a pipe support.
- a pipe support is to be understood as an element which is provided in connection with other elements to support a ceiling formwork and to hold it in position.
- the pipe support can be designed in various ways.
- Such a pipe support comprises at least one support head. This support head forms an axial end of the pipe support.
- the prop head can either be connected to a further element, for example to a formwork support head described above, or it can be set up on the floor.
- pipe supports comprise two support heads which are arranged at both ends of the pipe support.
- a pipe support also has a supporting area arranged between them. This carrying area is designed to be adjustable in length.
- the support area comprises at least two pipe pieces, which are designed to be adjustable in their total length via a thread.
- the support head is designed in the form of a plate and is usually formed by a metal plate.
- the support head has an end face facing away from the support area, which serves to transmit compressive forces to adjacent elements.
- a connection element is connected to a support head. This connection is designed to be detachable, so that the pipe support and connecting element can optionally be connected to one another or separated from one another.
- the end face of the prop head facing away from the support area rests flat on the support surface of the base element. This results in a good transmission of forces, in particular of compressive forces between the connecting element and the pipe support ensured.
- the support head In the assembled state, the support head is clamped against the base element by the bracket of the connecting element.
- the length of the bearing elements of the connecting element is selected in a connecting system according to the invention so that when the clamping element is not actuated, the distance between the contact surface of the base element and the contact side of the bracket is greater than the plate thickness of the support head.
- the bracket can be pivoted with play over the support head placed on the support surface and connected to the second bearing element. Then the clamping elements are actuated and the support head is clamped between the support surface and the bracket.
- the connecting element or the connecting system is thus suitable for making connections with differently designed pipe supports.
- pipe supports with different panel thicknesses can be flexibly clamped by one and the same connecting element.
- pipe supports from different manufacturers can also be connected to one connecting element.
- This is beneficial for flexibility on the construction site. Pipe supports from different manufacturers and different designs are often used, especially on larger construction sites. Due to the flexibility of the connecting element, the logistical effort on the construction site is significantly reduced compared to the prior art. As has already been shown in the embodiments of the connecting element, the connecting system is also simple and robust and can be operated without special tools.
- the central area of the bracket in the assembled state of the connection system encompasses at least part of the support area of the tubular support.
- the support area of the pipe support comprises a cylindrical pipe.
- the bracket of the connecting element has an arcuate central area, in the assembled state, when the bracket is connected to both bearing elements, this central area encompasses at least part of the support area of the pipe supports.
- the contact side of the bracket lies flat and around the support area of the tubular support on the support head. The introduction of the clamping force between the connecting element and the prop head is thus distributed over large areas of the prop head. The connection between the two components is therefore very stable.
- connection system is also suitable for absorbing asymmetrically introduced loads.
- the arc-shaped central area of the bracket also enables the connection element to be connected to tubular supports which have a supporting area with different diameters.
- the radius of the arc-shaped central area is selected approximately in accordance with the radius of the largest expected diameter of a supporting area of a pipe support. Pipe supports with a supporting area with a smaller diameter can easily be clamped by the same bracket.
- the connection system is therefore also suitable for pipe supports with different diameters of the bearing area.
- the prop head has at least one bore and, in addition to being clamped between the base element and bracket, the prop head can be connected to the connecting element by a mounting element, the additional mounting element penetrating the bore in the prop head and the recess in the base plate .
- an additional clamping option is provided between the connection element and the pipe support. This additional clamping possibility is made possible, for example, by one or more screw connections, this screw connection being guided through a recess in the base element of the connecting element and at the same time through a bore in the support head.
- Such an additional mounting element additionally increases the stability of the connection between the connecting element and the pipe support.
- the free length of the bearing elements extending between the support surface and the contact side in the assembled state is made variable due to the wedge-shaped areas of the clamping elements, whereby support heads with different plate thicknesses can be clamped in the connecting element.
- the free length of the bearing elements is to be understood as the distance that extends between the support surface and the contact side in the assembled state. This distance can be changed by actuating the clamping elements.
- the free length also corresponds to the distance that is available to insert a column head with a plate thickness. Due to the variability of the free length, column heads with variable panel thickness can be placed between Bracket and base element are introduced.
- the free length is usually chosen between 1 and 15 mm, in particular between 5 and 10 mm.
- a method for connecting a connecting element according to one of the previously described embodiments to a pipe support having a support area and at least one support head and the support head being designed in the form of a plate, the plate-shaped support head having a plate thickness comprising the steps,
- the bracket of the connecting element is pivoted away from the base element around a first bearing element and around the pivot mount. In this pivoted-away state, the bracket does not prevent the pipe support from being fed to the connecting element.
- the pipe support is brought into connection with the connecting element.
- the tubular support is guided with the end face of the support head first in the direction of the support surface. This merging is ended as soon as the end face of the prop head facing away from the support area rests on the support surface.
- the pipe support is still rotated around its longitudinal axis in order to achieve optimal overlap between the support head and the base element.
- the bracket is then pivoted back in the direction of the base element until the closing receptacle of the bracket receives and engages around the second bearing element. During this pivoting of the bracket, the prop head is enclosed between the bracket and the base element.
- the bracket which is at least partially curved, encompasses the tubular support, in particular its support area.
- the tensioning elements are actuated, i. H. moved in a linear direction.
- This linear movement is translated into a likewise linear movement of the bearing elements or the pressure areas of the clamping elements via the wedge-shaped areas of the clamping elements.
- This second linear movement moves the bracket in the direction of the support surface and clamps the support head enclosed between the support surface and the support side of the bracket.
- the clamping elements can be actuated by hand or with the aid of a simple tool such as a hammer, which is used to strike the clamping elements.
- the bearing element can no longer be displaced relative to the clamping body in a direction parallel to its sliding area.
- the tensioning element and bearing element can no longer be separated from one another. This is advantageous because the tensioning element cannot be lost and the functionality of the subassembly is thus always guaranteed.
