PURPOSE:To secure an inner tank to the heat insulation layer in a reasonable and simplified way by providing this insulation layer with receptacles and the inner tank with metal fittings. CONSTITUTION:In a heat insulation panel 1 forming an insulation layer and situated inside the outer shell 3 of concrete housing, receptacles 5 each having a hole 8, a recess 9 and a ring-shaped groove 10 are provided. On a membrane 4 forming an inner tank, metal fittings 6 to be fit in the receptacles 5 are provided. If the membrane 4 covering the insulation panel 1 which is fixed previously to the shell 3, is placed in a designed position and every metal fitting 6 is pushed into their mating receptacles 5, the tip 6' fits in the recess 9 and ring-shaped groove 10. Thus, the membrane 4 is fixed to the insulation panel 1 firmly. No boring work is required here different from the conventional method in which a tank interior is secured to an insulation panel using anchoring metals. |
