Unilateral formwork for basement exterior wall

The utility model discloses a unilateral formwork for a basement exterior wall, which comprises a plurality of panels, supporting columns are connected between adjacent panels, the supporting columns are obliquely arranged, one ends of the supporting columns are fixedly connected with the panels, and the other ends of the supporting columns abut against the ground. Supporting plates used for being connected with the adjacent panels are movably arranged at the ends, close to the panels, of the supporting columns, first buffering mechanisms are arranged between the supporting plates and the supporting columns, and the supporting plates are in pivot connection with the corresponding panels. A second buffering mechanism used for giving reverse elastic acting force to the panels when the panels are stressed towards the supporting column along the pivot joint is further arranged between the panels on the supporting plate, the supporting plate extends towards the supporting column to be provided with a supporting ar
