The invention provides a prestress clamp used for flexible age forming. The clamp comprises two supports, multiple upper cross beams, multiple lower cross beams and a positioning assembly, wherein each support is provided with an upper sliding rail and a lower sliding rail which extend in the horizontal direction and are parallel; the multiple upper cross beams are supported between the two supports; the multiple lower cross beams are supported between the two supports; the positioning assembly comprises positioning cross beams and positioning pins and is arranged between the two supports; the positioning pins are perpendicularly installed on the positioning cross beams to support a wallboard workpiece; upper pressure rods of the upper cross beams penetrate through threaded holes of the upper cross beams to press the wallboard workpiece; lower pressure rods are provided with pressure heads used for supporting the wallboard workpiece, so that the wallboard workpiece is supported between the upper cross beams and the lower cross beams. The prestress clamp can achieve hyperbolicity loading of the wallboard workpiece.
