柱体を配置する。Accordingly, a plurality of reinforcing columns are provided in the flat container. For example, when the thickness of the flat plate is 2 mm, the stainless steel plate can withstand the internal pressure of 1 MPa without deforming the flat plate. In view of the allowable tensile stress value of the stainless steel plate, the interval between the support members is set to 36 mm or less. Arrange the columns.

FIG. 5 is a diagram showing a state in which the support 4 is incorporated between two flat plates. FIG. 6 is a state diagram in which the frame member 5 is incorporated between two flat plate members. The outer shape of the support body is cylindrical or prismatic, and the support body to be incorporated in the flat plate has steps at the top and bottom. This step is for the purpose of preventing the displacement between the flat plate and the support. In addition, as shown in FIG. 3, in the state where the support is incorporated between the two flat members, the step of the support is lower than that of the flat member before joining. This is to suppress thermal deformation of the flat plate after welding. The flat plate 2 and the support member 4 and the flat plate 2 and the frame member 5 are joined by welding or brazing.
