Prefabricated building pre-embedded vertical row sleeve alignment equipment

The invention belongs to the technical field of building equipment, and particularly provides prefabricated building pre-embedded vertical row sleeve alignment equipment which comprises a longitudinal and transverse touch feedback device and a vertical positioning supporting leg, and the longitudinal and transverse touch feedback device is arranged at the upper end of the vertical positioning supporting leg. The equipment is convenient to turn over by utilizing a bidirectional telescopic structure, then stable connection with a poured floor of a fabricated building is realized in a double-layer temporary fixed connection manner, and the perpendicularity of the equipment is adjusted, so that an alignment calibration reference is provided for hoisting of a laminated slab, and the hoisting efficiency of the laminated slab is improved. The technical problem that an embedded sleeve in a narrow space at the corner of a wall is difficult to effectively fix is effectively solved, the laminated slab embedded sleeve is
