PROBLEM TO BE SOLVED: To provide a nozzle reinforcement structure of a low-temperature storage tank capable of softening the load condition of a radial-direction fixed member or a peripheral-direction fixed member.SOLUTION: A nozzle reinforcement structure 30 for fixing a nozzle 10 vertically extending through the roof of a low-temperature storage tank to the vicinity of a bottom part includes a nozzle fixing frame part 24 having two radial-direction fixed members 21A extending in a radial direction and two peripheral-direction fixed members 23A and 15A extending in a peripheral direction in the roof, a flange member 31 fixed to the nozzle disposed in the internal space of the nozzle fixing frame part 24, and a plurality of reinforcing bones 32 and 33 for securing the flange part 31 at least three intersection joined parts among four intersection joined parts 25 and 26 in which the two radial-direction fixed members 21A and the two peripheral-direction fixed members 23A and 15A are joined together in an intersection manner.SELECTED DRAWING: Figure 5 |
