Shear wall formwork support structure

The utility model discloses a shear wall formwork support structure. The structure comprises a pre-embedded part, a jackscrew, a steel tube nested on the jackscrew, an adjusting fastener fixedly mounted in the middle of the steel tube, an upper fastener fixedly mounted at the top end of the steel tube and an inclination angle adjusting mechanism mounted on the outer side of the steel tube by the aid of the adjusting fastener, wherein the pre-embedded part is a saddle-shaped steel part embedded in concrete of a lower floor; the adjusting mechanism comprises a left-turned E-shaped part fastened on the adjusting fastener, a pull rod penetrating through the left-turned E-shaped part and a nut matched with the upper end of the pull rod, the pull rod is parallel to the steel tube, and the lower end of the pull rod is connected with the pre-embedded part. The shear wall formwork support structure has the advantages as follows: steel tube reinforced wall formworks are matched with and mounted on two sides of a wall formwork support which is supported well, bottoms of the steel tube reinforced wall formworks are propped against the pre-embedded part by the jackscrew, the wall formworks and the wall formwork support are utilized to bear the weight of a head die, the die supporting time is shortened, the position between the top die and each wall formwork is controlled conveniently, and the probability of relative displacement is low.
