PURPOSE:To increase the strength of the foundation of a membrane by burying the membrane foundation into a heat-insulating layer and adopting a structure of multiple pipes connected by return parts for the membrane foundation to keep the membrane at a fixed position. CONSTITUTION:A membrane foundation 5 is composed of double cylinders 6 connected by two return parts, a horizontal flat plate base 7 of a regular square welded at the lower end of the double cylinders 6, a member 8 with a flange 8a extended toward the center of the double cylinders 6 to cover the upper part, and a welded boss 9. After a heat-insulating panel 2 is fixed on a concrete body 10 to surround the installing position of the membrane foundation, a urethane foam board 13 is laid. Then, a membrane 3 is fast fixed on the concrete body 10 via the membrane foundation 5 and fixing bolts 11 at a fixed position with a strength highly increased. |
