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.
Claims15
A double walled body comprising:
- first and second spaced apart cover panels with a surface on one panel opposed to a surface on the other panel;
- a plurality of apertures defined in the cover panels, the cover panels being so placed and the apertures being so placed in the cover panels that the apertures are in respective sets with one aperture in each of the panels;
- respective pluralities of first and second cylinder shaped spacers, each spacer having an axis through the cover panels;
- the first spacers each having a length along its axis corresponding to the clear width distance between the cover panels to engage the opposed surfaces of the cover panels;
- the second spacers each having axially opposite end regions and each second spacer being of a length to cause its end regions to extend in a respective set of apertures in the cover panels for the respective spacer;
- whereby both of the first and second spacers support the cover panels.
