<P>PROBLEM TO BE SOLVED: To provide a pedestal with a built-in flow path capable of forming a hollow structure functioning as a large-diameter piping or a tank, without enlarging the thickness of a flat plate constituting the pedestal. <P>SOLUTION: A flow path 30 with a cross section (a size h3 in a thickness direction of the plate) larger than that (sizes h1, h2 in the thickness direction of the plate) of a groove 27 (the built-in flow path) is formed by jointing a flow path member 28 with one side surface of the pedestal (a lower plate surface 23c or a top plate surface 22a) or with both-side surfaces of the pedestal (the lower plate surface and top plate surface). Further, a tank with a cross section (a size in a thickness direction of the plate) larger than that (the size in the thickness direction of the plate) of the groove (the built-in flow path) is formed by jointing a tank member with one side surface of the pedestal (the top plate surface or the lower plate surface) or with the both surfaces of the pedestal. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
