Abstract

PURPOSE: To relieve the production of ice pressure in a manner to break an ice plate with a bending moment and to enable the rational use of a structure material, by a method wherein fins, which have a chevron shape cross section, are positioned at a part of a leg stay, which makes contact with an ice plate, so that fins are attached at given pitches in a manner to be titled against a horizontal plane.
CONSTITUTION: A leg stay 1 is formed into a column or the similar shape to the column and spiral fins, which have a chevron shape cross section, are located at given pitches P1 at a part where the leg stay makes contact with an ice plate 3. The pitch P1 of the spiral fin 4 is set to be larger than the thickness of the ice plate on ice waters. The spiral fin 4 has an inclining angle θ1, while incling angles θ2, and θ3 are preferably below 75°. When the ice plate enters into between the spiral fins 4, it is caused to enter into along the upper surface and the lower surface of the spiral fin, and the ice plate is broken with a bending breakdown moment.
