Reusable pre-embedded formwork erecting and positioning angle brace

The utility model relates to the technical field of formwork erecting, in particular to a reusable positioning angle brace for erecting a pre-embedded formwork, and overcomes the defect that a positioning rib is used for positioning the formwork. A reusable embedded formwork erecting and positioning angle brace comprises a vertical formwork and a transverse formwork and further comprises a fixed bottom plate and an L-shaped limiting plate. The fixed bottom plate is arranged on the upper surface of the transverse template; two connecting pipes extend from the upper surface of the fixed bottom plate, and internal threads are arranged on the inner pipe walls of the two connecting pipes; an embedded screw rod is screwed in each connecting pipe; a concrete layer is poured on the transverse formwork, and the middle portion and the lower portion of the embedded screw are embedded in the concrete layer. Two mounting holes are formed in the plate surface of the transverse section of the L-shaped limiting plate; the tw
