A self-mounting modular structure comprises profiled peripheral columns (1, T) which exhibit upper overlapped and spaced fulcrums (2, 2'), wherein the rear portions of two series of crosspieces (3, 3') engage, the front ends whereof connect to upper (4) and lower (41) fulcrums of the central support rack (5) of a control unit (6) the stem whereof (7) connects, through a coaxial joint (8) and movable radial levers (9), to the front extensions (3'') of the lower crosspieces (31). In feedback, the stem (7) rises and pushes the columns (1, T) outwards, which move on standard or roller tracked wheels (11), causing the lifting in the middle and "at the ceiling" of the crosspieces (3, 3'), located within the same columns. Peripheral section bars (19), also comprised in closure in the peripheral columns (1, T), delimit the structure with roll-up sheets (21), along with an upper cover (22) engaged, in the middle, with said rack (5). |
