Definitions
- the invention relates to a connecting clip for
- Formwork construction in particular for concrete formwork construction, with an inner clamp arm and an outer clamp arm, the two clamp arms each having a clamp jaw and being movable relative to one another for adjusting a clamp width of the connecting clamp, and the inner clamp arm having a plug-in section which is inserted into a guide section of the outer Clamp arm inserted and guided in this.
- the invention also relates to structural formwork,
- Formwork element and a connecting bracket Formwork element and a connecting bracket.
- Connecting clamps of the type mentioned are known and are used for the construction of building formwork. With the help of the building formwork, concrete walls and concrete ceilings are poured. The connecting clamps are used to firmly connect the formwork elements of the building formwork to one another in the position of use before the concrete is poured.
- the object of the invention is to provide a connecting clip of the type mentioned at the outset which, with comparable or unchanged stability, has a lower weight than the previously known connecting clips.
- connection clip of the type mentioned above
- Clamp arm has a cavity at least in its plug-in section. So far it has been common in the prior art that to produce inner clamp arms of such connecting clamps from a solid material.
- the connecting clamp is lighter than the connecting clamps of comparable size and load capacity known from the prior art. This is due to the cavity in the connecting clamps of comparable size and load capacity known from the prior art. This is due to the cavity in the connecting clamps of comparable size and load capacity known from the prior art. This is due to the cavity in the connecting clamps of comparable size and load capacity known from the prior art.

This is due to the cavity in the connecting clamps of comparable size and load capacity known from the prior art. This is due to the cavity in the connecting clamps of comparable size and load capacity known from the prior art.
- the clamp arm has a stability comparable to that of the previously known ones
- the inner clamp arm has, at least in its plug-in section, a profile that defines the cavity
- the profile of the inner clamp arm can be designed so that it encloses the cavity on all sides.
- the profile of the clamp arm can be a closed or, for example, a hollow profile open at least on one side, at least in the plug-in section of the clamp arm.
- Guide direction is formed continuously in the plug portion of the inner clamp arm. In this way, particularly high weight savings can be achieved.
- connection clip When the connection clip is in the position of use, the connection clip can comprise a tensioning element.
- the clamping element can be inserted through a recess of the outer clamp arm and a recess of the inner clamp arm and into Locking and / or clamping position of the clamping element
- the tensioning element has a tensioning slope with which the two clamp arms can be braced against one another.
- the clamping slope is through a

- a rectangular, preferably non-square basic shape is favorable to the
- a long side of the rectangular and / or oval and / or oval-rectangular basic shape of the profile (s) can be oriented in the direction of the clamp jaws of the clamp arms. This way it is rectangular
- the inner clip arm has a step and / or a grid. It is thus possible, for example, the previously mentioned clamping element, which can also function as a locking element, in its clamping and / or clamping arms when the clamp arms are in different relative positions
- the gradation and / or the grid can be different
- the bracket width of the connecting bracket can be increased or reduced as desired, for example to be able to use the connecting bracket when intermediate elements are to be used between two formwork elements to be connected to the connecting bracket to compensate for structural dimensions and / or tolerances.

- clamp jaw of the outer clamp arm can span a right angle with the guide section of the outer clamp arm. Furthermore, the jaw of the inner clamp arm with the
- the plug-in section of the inner clamp arm also spans a right angle.
- the guide section of the outer clamp arm and the plug section of the inner clamp arm are dimensioned such that the guide section engages around and supports the plug section when the clamp width of the connecting clamp is set to the maximum.
- the guide section supports the plug-in section when the clamp width of the connecting clamp is set to the maximum, in particular on both sides, in the region of a jaw limb of the inner clamp arm.
- connection bracket on the one hand a pleasing appearance in all working positions. On the other hand, it is ensured that the outer bracket arm of the connecting bracket can also absorb load over its entire length in this most extended position. Ultimately, this leads to the fact that the inner gripper arm can be designed with lower stability and correspondingly lower material usage and thus also correspondingly lower weight.
- Each of the two clamp arms can have a cheek piece
- the jaw limb of the inner clamp arm can be oriented transversely or at right angles to the plug-in section of the inner clamp arm.
- the jaw limb of the outer clamp arm can be oriented transversely or at right angles to the guide section of the outer clamp arm.
