PROBLEM TO BE SOLVED: To provide a barrel tank partition wall that can partition a barrel tank easily in an optional place and can be assembled into the barrel tank with stabler force. SOLUTION: A partition wall 1 is composed of a main part 2 of hexagonal shape conformed to the cross-sectional shape of a barrel tank 5, and a press- fitting part 3 adjusted to a press-in groove 10 opened in isosceles triangular shape to one side of the main part 2. The main part 2 is placed in a requested position of the barrel tank 5, and the press-fitting part 3 is lightly fitted into the press-in groove 10. When a bolt 4A is passed through an insert hole 12 and a bolt receiving hole 11 and turned into a nut 4B, the press-fitting part 3 is firmly assembled to the main part 2. At this time, since the press-fitting part 3 is formed at a slightly larger angle than the press-in groove 10, the main part 2 is deformed open, so that a pressure-fitted edge 16 is pressure-fitted to the internal wall of the barrel tank 5. |
