| 摘要 |
<p>The invention relates to a flat structure, comprising two elongate parallel carriers and metal main profiles extending substantially transversely of the carriers, wherein this measure results in a considerably stronger construction, this being caused mainly by the fact that a load on the structure, in particular a transverse load, is distributed over several main profiles by the auxiliary profiles. Such a structure can hereby be loaded more heavily or it can be given a smaller construction for the same load, which results in lower costs. <IMAGE></p> |
