Safety protection device for building construction elevator shaft

The utility model particularly relates to a safety protection device of a building construction elevator shaft. The safety protection device solves the problems that an existing safety protection table of the elevator shaft is large in construction difficulty and dismantling difficulty, the construction process is dangerous, and protection is not tight. A safety protection device of a building construction elevator shaft comprises a reinforcing mesh, a protection frame and a protection plate. The four edges of the reinforcing mesh are embedded in four shear walls or beams of an elevator shaft correspondingly, and the size of the protection frame is matched with the size of a well mouth of the elevator shaft. The size of the protection plate is smaller than that of the protection frame; the reinforcing mesh comprises a plurality of transverse reinforcing steel bars and a plurality of longitudinal reinforcing steel bars; the protective frame is composed of two main keels and a plurality of auxiliary keels.
