- Scaffolding is used in the construction sector for various tasks. Facade scaffolding is used to design the outer surfaces of buildings, for example to paint them. Furthermore, elements required for the erection of buildings, such as makeshift constructions or formwork with shoring, can be positioned. Finally, scaffolding is also used in the service or revision area, for example to bring workers safely to the parts of the plant to be overhauled in large process engineering plants, such as refineries.
- Scaffolding has horizontally oriented levels on which workers can stay and move.
- These horizontal planes are formed by horizontal bars, which are attached in the horizontal direction to vertically running scaffolding elements, for example vertical posts.
- a horizontal plane can be formed by a frame made of four horizontal bars arranged at right angles to one another.
- Various coverings can be applied to such a frame, which then form the tread surface of the level.

- no tool is required to create the connection, which greatly simplifies the handling of the element receptacle compared to the known prior art.
- the connection created is free of play, which means that there is a direct transmission of force between the element holder and the two scaffolding elements. The connection no longer has any degrees of freedom, making it very stable and reliable.
- This play-free, non-positive connection is particularly advantageous if a bracket is to be attached to a scaffolding element that has already been positioned using the element holder.
- an already positioned scaffolding element creates a non-positive connection, in which a flow of forces flows through the components in different ways, which further increases the stability of the connection.
- part of the power flow is guided via the first tensioning section and another part of the power flow is guided via the second tensioning section between the element holder and the scaffolding element that has already been positioned or the further scaffolding element.

- the position of use of the element holder 1 is shown, in which it can be firmly connected to an already positioned scaffolding element, for example a horizontal bar 20.
- a connection system 100 in a corresponding position of use, with the illustrated, already positioned horizontal bar 20 can be seen in FIG.
- the hanging element 121, the contact surface 123, the gripping surface 114 and the clamping surface S1 together form an undercut into which a scaffolding element to be positioned can be introduced.
- a framework element introduced into this undercut is then surrounded by the element receptacle 1 in such a way that the element receptacle can no longer be separated from the framework element that has already been positioned.
- the contact surface 123 is oriented essentially at right angles to the gripping surface 114 .
- the two clamping surfaces S1 and S2 are oriented essentially parallel to the contact surface 123 and to the holding surface 121c on the suspension element 121.
- the area of the base body 110 which in the representation of the holder 12 points to the right, is also oriented essentially at right angles to the contact surface 123 .
- the connecting part 115 can be seen clearly, which is used for the additional connection of receptacle 11 and holder 12.
- a recess 115a is arranged approximately centrally in the connecting part 115 .
- the end section of the holder 12 pointing away from the suspension element 121 is introduced into the recess 115a of the connecting element 115 and is partially surrounded by it.
- This area of the holder 12, which is arranged below the counter-joint area 112 is thus surrounded around its entire circumference by the combination of connecting part 115 and base body 110.
- the receptacle 11 cannot be separated from the holder 12, although the two components are connected to one another so that they can move relative to one another.
- the base body 110 is first pushed into the counter-joint area 122 in such a way that the joint area 112 is arranged within the counter-joint area 122 .
- the connecting part 115 is then pushed with its recess 115a over the downward-pointing part of the holder 12 and is connected via two surfaces to the downward-pointing surface of the base body 110 by means of welded connections.
- the recess 115a has an essentially rectangular shape in the illustrated side view. However, the recess 115a can also have a different shape, for example the shape of a semicircle or some other shape.
- the shape of the downwardly oriented, second clamping section 113b can be seen clearly. In the area in which the second clamping section 113b adjoins the base body 110, it is wedge-shaped and tapers as the distance from the base body 110 increases bending axis and, on the other hand, compact and lightweight.
- the planar second clamping surface S2 is arranged pointing to the right, which is provided for force transmission with the connection interface 22 of a horizontal ledger 20.
- force is introduced into the second clamping section 113b via the second clamping surface S2, which force is passed on by the second clamping section 113b and guided to the base body 110 and to the first clamping section 113a.

- the receptacle 11 was then rotated about the first spatial axis A1, so that in the state shown, the gripping surface 114 and the contact surface 123 are oriented essentially at right angles to one another.
- the gripping surface 114 is already in contact with the downward-facing broad side surface 21a of the first horizontal bar 20 .
- the contact surface 123 rests against the high side wall 21b facing to the right. It can be seen that in the illustrated State the first clamping surface S1 is not yet applied to the first horizontal bar 20. Furthermore, the second clamping surface S2 is not yet in contact with the connection interface 22 of the second horizontal bar 20 .
- the state shown shows a position of the element holder 1, which is between the assembly position and the use position.
- a connection interface 22 is arranged on the second horizontal bar 20 on its side facing the element receptacle 1 . This connection interface 22 has a number of sub-areas.

- connection system 100 The components of the connection system 100 are thus non-positively connected or braced to one another by two force flows that are routed along different paths.
- the actuating element 22A In order to dismantle the connection system 100, the actuating element 22A is moved back up again starting from its position of use shown in FIG. 7, as a result of which the tension between the three components is released. In the non-tensioned state, the components can then be separated from one another again in the reverse order as described above.
- FIG. 8 shows a perspective view of a second embodiment of an element holder 1 according to the invention.
- the second embodiment shown in FIG. 8 differs from the embodiment shown in FIG , In particular the clamping area 113, the hanging element 121, the receiving interface 111, the gripping surface 114 and the contact surface 123 are identical to the first embodiment and are therefore not described again in detail.
