摘要

The construction element comprises interconnected concreted panels (4, 5) with a filler in the interspace. Full-length grooves are provided over the length of opposite end sides and are connected together through transversely aligned chimney-like cavities (6) which are formed by shuttering bodies (7) concreted in between the panels.
