PURPOSE: A structure support with a breakaway prevention unit for a wear plate is provided to prevent a wear plate from breaking away by forming and integrally connecting a wedge-shaped groove on a middle plate and a wedge-shaped projection on the wear plate. CONSTITUTION: A structure support (100) with a breakaway prevention unit for a wear plate includes an upper plate (110), a lower plate (120), a middle plate (130), a wear plate (140), and a breakaway prevention unit (160). The wear plate has the lower side which is settled and fixed in the concavo groove of the upper side of the middle plate in order to prevent wear of the middle plate due to friction which is generated in between the upper plate and the middle plate. The breakaway prevention unit is formed in between the concavo groove of the upper side of the middle plate and the lower side of the wear plate, and prevents the wear plate from breaking away. The breakaway prevention unit is formed to have a wedge-shaped groove which is formed on the middle plate and a wedge-shaped projection which is protruded from the wear plate. |
