The invention relates to a runner holder divided into a first part and a second part, the first part comprising a first end of the runner holder and the second part comprising a second end of the runner holder, opposite the first end, the first part having a projection inserted into an inlet of the second part, which projection can slide into the entrance such that the length of the runner holder can be adjusted. The runner holder further comprises at least one pressure means situated at the first end and/or the second end.

Formwork support comprising an outer support part and a telescopic inner support part, wherein the inner support part comprises a twist-proof portion and the outer support part comprises a twist-proof region with a first inner contour, wherein during telescoping of the inner support part, the twist-proof region of the outer support part cooperates with the twist-proof portion of the inner support part in such a manner that a twisting of the inner support part about its longitudinal axis with respect to the outer support part is blocked, wherein the outer support part comprises a guide region with a second inner contour which differs from the first inner contour for guiding the inner support part.

The present disclosure is directed to climbing wall assemblies having a variety of improvements. For instance, the climbing wall assemblies may include connectors to attach the surface panels to the framework, in which the connectors may be mounted substantially anywhere along the front of the framework and at substantially any angle, providing for the securement of climbing panels in various geometries. The climbing wall assemblies may also include braces that may easily be adjusted to a desired length and configuration during construction of a climbing wall. The climbing wall assemblies may also include variable-angle, integral front posts, which provide for the easy and stable securement of climbing panels in various geometries. These improvements provide climbing wall assemblies that may be easily assembled to produce a desirable climbing wall structure having few framework components.

Diagonal reinforcement for floor formwork support structures, the support structure comprising height-adjustable props on which diagonal reinforcements are mounted, wherein each of the diagonal reinforcements comprises a projecting pivot close to the upper end thereof, or on the upper end itself, the free end of which pivot is deformed towards one side and can fit progressively into one of the holes in the prop on which the pivot is mounted by means of rotation, it being possible to detach the reinforcement simply by reproducing the insertion movement in reverse.
