Anti-cracking prefabricated L-shaped corner column

The utility model discloses an anti-cracking prefabricated L-shaped corner column. The anti-cracking prefabricated L-shaped corner column comprises an L-shaped corner column body, vertical prefabricated slurry storage grooves are formed in the two side faces of the L-shaped corner column body in the height direction, and joint grooves are formed in the two sides of the L-shaped corner column body.According to the L-shaped corner column body, after the L-shaped corner column body is spliced with the adjacent inner partition wall battens, mortar is densely filled in a prefabricated mortar storage channel defined by the L-shaped corner column body and the adjacent inner partition wall battens to form a secondary connecting body with the function of an inner bolt for fixed connection, and theproblem that the splicing position of an existing L-shaped corner plate and an adjacent inner wall partition plate cracks is solved; net laying and plastering are conducted in the seam grooves in theedges of the abutted seams
