<p>PURPOSE:To perform insulation work to the low temperature tank roof inside efficiently and safely by previously forming the insulation cover and cover the inside of roof plate or various supporting members by proper fixing measure. CONSTITUTION:Hard polyurethane foam insulation covers of various shapes are formed in a factory outside of the building site. In this case, they are formed previously to suit to the dimension and shape of the inside of the roof plate 4 or various supporting members 5, 6, 7. These various insulation covers are brought into the low temperature tank and attached selectively to fit to the places and assembled according to the purpose to cover places for heat insulation. Therefore, interior of the low temperature tank can be covered safely and efficiently without using spray foaming method or the like, and sure protection from the low temperature liquefied gas is obtained.</p> |
