Plastics water inflow cup cast in concrete ceiling - has battens on plastics supports plugged into grooves on side attachments

摘要

The plastic cup fits precisely into the service network and lies flush in the ceiling. The plastic cup for water inflow is cast into a concrete ceiling, and has a collar formed on at the top. Use is made of three or more plastics supports (20), with feet nailed to ceiling sheathing. A plug-in batten is formed lengthways on each, protruding in cross-section. Attachments are formed on the cup walling, directly below the collar (11), at equal angle intervals, each with a groove fitting a plug profile. This ensures accurate fitting in both directions.
