Circular formwork GRV

wallbridgecircular

Overview
The GRV articulated waler circular formwork enables circular concrete structures to be formed without tie points by transferring ring tension and compression through a closed ring of walers.

Product description
The closed ring of articulated walers transfers external ring tension and internal compression so that tie points or watertight anchor points are not required. Articulated connections between walers permit small radii to be shuttered and reduce handling at the site. Compatible with common formwork girders and shoring, the system is suited to containers, circular walls and arched bridges, offering material and installation savings where anchors would otherwise be needed.

Applications / In action

• Forming circular walls, tanks/containers and arched bridge structures without ties thanks to the closed waler ring.
• Cost-effective solution for larger radii and for repetitive production of identical circular elements.
• Suitable for containers, silos, clarifiers and various types of arched bridges.
• Can be combined with steel walers, formwork girders and shoring systems.
• Articulated walers allow very small internal radii (down to approx. 0.60 m); continuous adjustment possible for internal radii > 0.90 m.
• Possible traction forces up to ~300 kN depending on configuration.
