Shuttering for window-broken structures employs counter-form parts adjacently parallel at window breaks and filled out here by e.g. window closures with sealing.

摘要

The counter-form consists of parts (16,17) which together completely fill a window break (2,2a), the two counter-form parts arranged adjacently parallel to one side face of the concrete mold, or parallel to the shuttering surface (10). The two parts (16,17) should be closed off all round and spaced out in parallel and their interval filled by closures (3) as positively joined at the sides to the concrete, using seals (20) where the parts adjoin the shuttering surface (10). The concrete body lies between two shuttering faces (10) and is laid flush to the two faces.
