Claims

[Scope of utility model registration request]

A notch groove is circumferentially formed on the outer circumferential surface following both end faces of the square cylinder, and a connecting edge is fitted into one of the notch grooves to provide a protruding edge, and a square prism is formed at the corner of the inner circumference. A block for use in a propulsion construction method, in which a concave portion is formed into a concave shape, and through holes whose center lines coincide with each other are opened from both end faces into the concave portion.
