Steel cones are used for applications such as the construction of watertight concrete walls. The cones are supported at the inner side of the formwork and are fastened from the outside using a thread bar and a combination plate, flanged wing nut or equivalent accessories.Size accuracy of the formwork distance is achieved using a lost formtie/water stop Type N.
The steel cones are loosened via an easily accessible hex in the cone cover. The matching PE sleeve facilitates the loosening of the cone.

The slim edge cover defines a clear hole that can be easily closed with mortar. However, it leaves a clearly visible indentation in the formwork skin if the outer thread bar is over tightened. The wide edge cover prevents damages to the formwork skin.The hole that remains after unscrewing must be closed elaborately.

Shear forces and lateral pressure caused by steel brackets should be avoided when using anchor bars or products derived from Thread bars. Cones must be used for deflecting lateral forces.
