Formwork reinforcing support for fabricated precast beam construction

The utility model relates to the technical field of formwork reinforcing supports, and discloses a formwork reinforcing support for construction of an assembly type precast beam, which comprises a cross beam, a formwork reinforcing support body and a formwork reinforcing support body, and a sliding groove is formed in the middle of the front face of the cross beam; the adjusting mechanism is arranged in the sliding groove; the limiting mechanism is arranged in front of the cross beam; wherein the adjusting mechanism comprises a lead screw. By arranging the lead screw, the sliding block and the square block, the rotary knob is rotated by rotating the anti-skid sleeve, the rotating shaft can drive the first bevel gear to rotate, and due to the fact that the outer surface of the first bevel gear is in meshed connection with the outer surface of the second bevel gear, the second bevel gear can drive the lead screw to rotate through rotation of the first bevel gear; therefore, the two sliding blocks can drive the
