Be incorporated into the support structure of the ship, thermal insulation of the tank in a waterproof with improved corners structure

摘要

PROBLEM TO BE SOLVED: To provide a tank which is provided with a connection ring, arranged at the corner part of a tank, and having simple structure and reduced in a cost and easily fixed.;SOLUTION: A tank is provided with two continuous waterproof barrier, and a support structure is provided with a wall 1 and two lateral partition walls 2, of which the inside of a double hull consists, and the waterproof barrier is alternated with the heat insulation barrier. The corner part between this main and secondary heat insulation carrier parts is connected in a connection ring shape at a zone where the lateral partition wall 2 crosses an inner surface. Its structure is held along an intersection solid corner 3 between the lateral partition wall 2 and its inner wall. Each connection ring has an assembly type composite main beam 20 wherein a rigid metal form 21 is united with a heat insulation material 22, and the rigid form provides a central fixed mooring zone 29. This zone 29 is located at an intersection part between a plane to divide a connection corner part into two sections and the extension part of a secondary waterproof barrier so that it is fixed at the central fixed mooring zone. The opposite terminal 23 of the form is fixed at support structure by a fixing means 26 supported by the lateral partition wall and the inner surface.;COPYRIGHT: (C)2000,JPO
