FIELD: construction.
SUBSTANCE: group of inventions relates to a suspended ceiling structure of a membrane tank and a membrane tank. Suspended ceiling structure of membrane tank includes central ceiling component (110) and several cantilever beams (120) distributed in circumferential direction around central ceiling component. First end of each cantilever beam has inclined abutment surface (121). Surface (113) of the edge side of the central ceiling component is inclined, and the first end of each cantilever beam is movably connected to the central ceiling component, and each cantilever beam has an unfolded state and a folded state. Cantilever beam is in unfolded state, abutment surface adjoins surface of edge side. Second end of the cantilever beam extends from the centre of the central ceiling component, and the entire cantilever beam extends along the plane in which the central ceiling component is located, and both the lower edge of the edge side surface and the lower edge of the abutment surface are inclined away from the centre of the central ceiling component. When the cantilever beam is in a folded state, the cantilever beam is inclined to the central ceiling component.
EFFECT: reduced complexity of construction and risk during welding on upper part of inner tank wall.
