When the vertical dimension of window and column is not consistent with the modulus of face brick, the cutting must be symmetrical, and zero adjustment is not allowed. The size of face brick cut on both sides should be consistent and the joint should be uniform.
2. The pressing direction of facing brick should be correct, the side brick of window should be cut 2 ~ 3mm of frame edge, both sides of door and window frame should be uniform, the flashing slope of window sill and waist line should not be less than 5%, and the molding of face brick at the lower opening of window frame should not exceed the main frame.
