Supporting platform for elevator shaft protection and construction

The utility model relates to the technical field of elevator shaft construction, and particularly discloses a supporting platform for elevator shaft protection and construction, which comprises a platform plate, supporting beams respectively arranged on two sides below the platform plate, and a plurality of secondary beams fixedly connected between the supporting beams and the platform plate at equal intervals, the outer side ends of the supporting legs rotating to be horizontal extend to the outer sides of the supporting beams, balance weight structures are further arranged at the inner side ends of the supporting legs at the two ends of the same supporting beam, and check blocks used for limiting the outer side ends of the supporting legs from rotating upwards to exceed the horizontal position are further arranged on the secondary beams below the platform plate. The problems that when a traditional operation construction platform is built at the bottom during elevator shaft construction, the workload of a p
