The corner portions 121a of the curve form of the secondary barrier 121 of curved form is configured centered on the B of interface.Pass through the secondary barrier of curved form
121, can be effectively combined the first corner thermal insulation board 110a being fabricated separately in the form of monolithic entity respectively and the second corner every
Hot plate 110b, and peel stress caused by thermal stress caused by very low temperature flow and the deformation of hull can be effectively coped with and cut
Shearing stress etc..At this point, clamping washer 5 and nut 6 on the stud 4, it is heat-insulated to be inserted into the first corner for insertion part 7
After the internal holes S1 of plate 110a and the second corner thermal insulation board 110b, the 8 equal work that close the lid can be performed.The work can also be
It is vertically fixed on the stud 4 of the Inner wall of ship body 2 and first corner thermal insulation board 110a is set and the second corner is heat-insulated
It is executed after plate 110b.
Secondly, configuring the (ginseng of flat part lower part thermal insulation board 10 in a manner of connecting with the secondary barrier 121 of curved form referring to Fig. 8
According to Fig. 2) the plate shaped secondary barrier 122 on top.In fig. 8, for convenience of explanation, flat part lower part thermal insulation board 10 is not shown.
Secondly, the secondary barrier 123 of engagement is arranged across the mode between corner lower part thermal insulation board 110, to cover song
Space between the secondary barrier 121 of face shape, and connect with the secondary barrier 121 of curved form and plate shaped secondary barrier 122.Curved form
Overlapped peripheral portion connects between secondary barrier 121 and plate shaped secondary barrier 122 and the secondary barrier 123 of engagement
It closes.
Secondly, being matched in a manner of corresponding with corner lower part thermal insulation board 110 on secondary barrier top with Fig. 9 referring to Fig.1
Set corner top thermal insulation board 160.
Secondly, distinguishing clamping washer on the internal holes S2 draw bolt 170 outstanding to corner top thermal insulation board 160
181 and nut 182, in the state that washer 181 is supported by top accessory plate 162, tightening nut 182 simultaneously pressurizes downwards.It is interior
Lid (not shown) can be used to cover for the upper end of portion hole S2.
Later, the setting work of barrier 190 of corner can be realized on 160 top of corner top thermal insulation board.
The setting work of the cargo hold corner barrier can cooperate barrier setting work in flat part to carry out in order.That is, can
It is arranged with the sequence with lower part thermal insulation board, secondary barrier, top thermal insulation board, a barrier.
Specific embodiment is illustrated above.But the present invention is not limited to the embodiments, for this hair
For bright person of an ordinary skill in the technical field, the technical idea main idea for the invention recorded in not departing from claims
In the case where, numerous variations implementation can be carried out.
