The cost for installing the hanging deck becomes high. In addition, when constructing a roof using the aerating method, the roof is smaller than the side wall diameter of the storage tank and is assembled on the ground within the side wall, making it impossible to install hanging decks in advance around the roof. There is a problem in that after the cold insulation material is installed in the attic, there is no scaffolding around the attic for installing the cold insulation material (installation of the cold insulation material), and there is also no mounting part to attach the cold insulation material itself.

ようになつている。 The roof 2 consists of a roof frame 3 and a roof plate 4 stretched over its upper surface, and rafters 5 are provided around its periphery. A temporary roof 6 is provided on the lower surface of the periphery of the roof 2 excluding the rafters 5. This temporary roof 6 has an annular mounting member 7 fixed to the lower surface of the periphery of the roof 2.
It consists of a member 8 attached vertically to this mounting member 7, and a member 9 extending from the lower part of this member 8 to the inner surface of the upper end of the side wall 1. is becoming possible.

As explained above, this idea is based on LPG,
In low-temperature storage tanks that store low-temperature liquids such as LNG,
The peripheral part of the roof, excluding the rafters, has a temporary roof formed by vertically descending members and members reaching the upper end of the storage tank side wall.This temporary roof is used as a scaffold for installing the cold insulation material, and the temporary roof is used to install the cold insulation material on the temporary roof. Since we constructed a cold insulation structure around the roof, it is possible to install the cold insulation material without installing a hanging deck in the attic, and in particular, the construction around the roof, which cannot be assembled on the ground, can be done using the temporary roof as a scaffold. It is easy to work, and to prevent sloshing, insulation around the roof can be easily achieved by installing a cold insulation material on the temporary roof.Furthermore, when air rising, a sealing member can be installed around the temporary roof. It has various effects such as being able to be implemented immediately.
