Abstract: A construction of metal walls or closed containers which are used for storage. A wall or shell formed of several sheets of metal (5, 6) juxtaposed at their longitudinal edges (9, 10), resting on longitudinal elements (2, 3) and transverse elements (4). The longitudinal edges of these metal sheets form receptors (13, 14) subject to pressure from transverse movable pushing elements, thereby maintaining one of the edges (9) in abutment with the other (10) and generating lateral, strengthening tension. A method of construction of any individual wall or container by immobilizing sheets of metal (5, 6) along their longitudinal edges (9, 10) on longitudinal elements using opposing transverse force exerted locally and at intervals along the entire length of two adjacent sheets of metal (5, 6).

Abstract: A protective and insulating enclosure for a transfer unit of the conveyor type, the enclosure formed by lateral sides consisting of panels (2) removably mounted between a bottom carrier profiled section (6) and a (7), the panels are separated laterally by joining profiled sections, a top cover formed by sloping panels (121) with an end housed so as to be encased in a linear cavity (134) in a rear top profiled section (127), a front end of the top panels bearing on the longitudinal top holding profiled section, and the top panels separated by lateral joining sections (128, 129), a bottom enclosure consisting of a central recovery channel (120), between two longitudinal bottom carrier profiled sections (6, 176, 177), the central recovery channel having removable plates (118, 119, 189) sloping towards the central recovery channel enabling all panels to be fitted and removed easily and rapidly without any tool or equipment.

Abstract: Silo for diverse products in bulk, particularly plastic bottles, characterized by a hull (2) constituting its walls, and being formed of thin plates (3) suspended from, or attached to respective horizontal (4) and vertical plates (5) carrying profiles constituting an external framework.This invention will primarily be of interest to constructors of stockage material for bulk products.
