摘要

The partition has two metallic walls (1, 2) spaced with respect to each other and including strutting units constituted of hollow patterns (3) which are obtained by punching the metallic wall (1). The hollow patterns form respective heads (31) with respect to the metallic wall (2). One of the patterns includes a drill (30) at the heads. A reinforcement material is disposed between the walls outside the heads. An independent claim is also included for an application of the partition to a strong box.
