摘要： An insulating construction for a low temperature liquified gas storage tank consists of a plurality of heat insulating blocks or plates of rigid foam, each covered with a gas-tight sheet bonded thereto and each bolted at its approximate center to the outer wall of the tank. The joints between adjacent plates are filled with a heat insulating material and a gas-tight cover is applied to the exposed portions of this filler material and to the exposed ends of the bolts. Preferably, the inner surfaces of the plates are separated from the outer wall of the tank by spacers, providing a space which is filled with a soft foam resin and which forms a passage for conducting any leakage gas from the tank to a pipe located in a plate below the bottom of the tank and discharging such gas to the outside of the insulating construction.
