Abstract

PURPOSE: To ensure verticl lifting of a tank roof while keeping it horizontally, by temporarily fitting a center pole at the center of the tank for guiding the lift of the roof.
CONSTITUTION: A center pole 6 is temporarily erected at the center of the tank, when the erection of side plate 1 has reaches a certain level of height. The temporary erection is conducted by vertically penetrating a siliding mechanism 7 fitted to the center of a pre-fabricated tank roof 5. Supporting wires are shown by 8 and 11. As the center pole 6 and the sliding mechanism 7 are assembled, a sealing device 12 is fitted to the roof 5 and all workers withdraw from a lower port of the side plate 1. Then the port is closed airtinght and compressed air is blown in from an air port 14 opening on the bottom plate 13. The roof 5 is thus gradually lifted horizontally, being guided by the center pole 6 and through the smooth transfer of the sliding mechanism 7
