<P>PROBLEM TO BE SOLVED: To provide a pressure container having a weld structure in which a plate material subjected to pressure or load is welded to wall surface members such as a barrel plate and an end plate, the pressure container being configured so that the concentration of stress in the weld structure is relaxed to suppress an increase in the amount of welding and in the thickness of the wall surface members. <P>SOLUTION: The pressure container has a weld structure portion in which an end of a top plate 22, which is mounted so as to partition the inside of the container body and which is subjected to pressure or load, is welded to the wall surface member 30 of the container body. The weld structure portion is provided with shape displacement points located at at least two portions including a weld 40, the two portion being the weld 40 and a stepped section 50. <P>COPYRIGHT: (C)2012,JPO&INPIT |
