Abstract:
PCT No. PCT/FR86/00016 Sec. 371 Date Sep. 22, 1986 Sec. 102(e) Date Sep. 22, 1986 PCT Filed Jan. 21, 1986 PCT Pub. No. WO86/04448 PCT Pub. Date Jul. 31, 1986.This reservoir is provided with a fluidtight covering of metal sheets (6) welded together by their edges and supported by beams (2) each comprising two section elements (16, 17), and three longitudinal channels. In cross-section, the first and second section elements each have the shape of a U, the second section element being substantially narrower than the first element and being fixed by the edge of its branches (18) to the bottom (19) of the first section element so as to define an inspection channel (20) having a closed cross-section, and two draining channels (21) having an open cross-section. The surface of the bottom of the second section element (17) which faces toward the exterior of the beam, is contained in the same plane as the edges (11) of the branches (22) of the first section element (16) so as to form the bearing surface (14) for two sheets (6) in the region of their weld head (15) which interconnects them.
