In the present invention, the liquefied gas storage tank may be a C-Type (C-Type) tank, and thus a bracket for fixing is required. In the present invention, the wooden support 10 is used as the support.
The wood bracket can be a fixed bracket or a sliding bracket.
The fixing support is of a support structure as follows: with the liquefied gas storage tank cooling to ultra-low temperature, even along the upper and lower left and right sides direction repeated contraction and expansion several times, above-mentioned fixed bolster also can not change the position, plays the fixed axle effect.
The sliding support is of a support structure as follows: the tank can be contracted and expanded under the condition of thermal contraction and expansion without great stress by forming the sliding groove.
In an embodiment of the present invention, the wood bracket 10 may be formed by bonding a plurality of wood bracket blocks (wood support blocks) with Resin (Resin).
Hard heat insulating materials 20 are provided in contact with both side surfaces of the wooden holder 10.
The hard thermal insulation material 20 may be damaged by contraction and expansion of the wooden holder 10 due to a rapid temperature change of the liquefied gas storage tank.
In the present invention, the soft heat insulating material 40 is provided between the wood bracket 10 and the hard heat insulating material 20, so that the hard heat insulating material 20 is not directly bonded to the wood bracket 10, and thus, stress generated in the hard heat insulating material 20 due to thermal contraction and expansion of the wood bracket 10 caused by contraction and expansion of the liquefied gas storage tank can be reduced.
In an embodiment of the present invention, the hard heat insulating material 20 may be polyurethane foam (polyurethane foam), polystyrene foam, extruded polystyrene, or the like, and preferably may be polyurethane foam.
In an embodiment of the present invention, the soft heat insulating material 40 may be soft polyurethane foam (soft polyurethane foam).
