A splicing structure of fair-faced concrete pouring formworks comprises a first formwork (1) and a second formwork (2). First edge sealing angle iron (3) and second edge sealing angle iron (5) are respectively fixed onto the first formwork (1) and the second formwork (2), first diagonal angle iron (4) and second diagonal angle iron (6) are respectively fixed onto the first edge sealing angle iron (3) and the second edge sealing angle iron (5), and two ends of a diagonal screw (7) respectively penetrate through preset holes on the first diagonal angle iron (4) and the second diagonal angle iron (6) and are screwed with nuts. The splicing structure has the advantages that corners can keep perpendicular, pouring slurry cannot seep from a joint of the two formworks, the quality of a project is guaranteed, and the attractiveness of the project is improved.
