本発明は、低温液化ガスのごとき低温貨物を収容するた
めのタンク（容器を含む）に関し、特にその防熱構造に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tank (including a container) for accommodating low-temperature cargo such as low-temperature liquefied gas, and particularly to a heat-insulating structure thereof.
従来より、低温貨物用タンクの外壁面に、ポリウレタン

待できないという問題点がある。Traditionally, a heat-insulating layer has been formed on the outer wall of a tank for low-temperature cargo by foaming polyurethane foam in-situ. - It takes a lot of work to create a heat-insulating layer, and despite the effort, there is a problem that it is not possible to uniformly form a heat-insulating layer or to expect a sufficient heat-insulating effect.

めることが難しく、依然として十分な防熱効果が期待で
鰺ないという問題点がある。Therefore, a technology has been developed in which a large number of heat-insulating panels are molded separately and these panels are connected together and installed along the tank wall. However, in the conventional heat-insulating panel mounting structure, the heat-insulating panels are attached to the tank wall. Since the heat insulating panel is attached directly to the tank wall, it is difficult to increase the precision of attaching the heat insulating panel to the tank wall, and there is still a problem in that sufficient heat insulating effects are not expected.
本発明は、このような問題点を解決しようとするもので

貨物用タンクの防熱構造を提供することを目的とする。The present invention aims to solve these problems, and provides a heat-insulating structure for low-temperature cargo tanks in which a heat-insulating panel can be attached to the tank wall with high precision and a sufficient heat-insulating effect can be obtained. The purpose is to provide.

している。For this reason, the heat-insulating structure of the present invention includes a large number of heat-insulating panels arranged along the wall surface of a low-temperature cargo tank, and each of these heat-insulating panels has a groove formed on its outer periphery, so that the heat-insulating panels are mutually connected. The tank is coupled to the tank through a spline 2-in that fits into the groove, and the spline is supported by a clip attached to the wall of the tank.
