Abstract

The invention proposes a double-walled body with cover panels between which spacers are arranged. The double-walled body is distinguished in that the spacers are designed as cylinders, in particular tubes (6), of which the cylinder axes run orthogonally with respect to the cover-panel surfaces, in that one set of tubes (6) (first tubes (7)) is of a length which corresponds to the clear width between the cover panels (3, 5), and in that another set of tubes (6) (second tubes (9)) engages in, or through, apertures (13) in the cover panels (3, 5) by way of the end regions (11) in each case, and in that the interior of at least some of the second tubes (9) accommodates fastening means, in particular threaded bushes.
