Abstract
The invention discloses an elevator shaft standard operation platform and an implementation method. The operation platform comprises a supporting frame, supporting legs, hanging rings and a formwork. The supporting frame is formed by welding box iron girders and box iron secondary beams. The supporting legs are composed of the rotary supporting legs and the fixed supporting legs. The rotary supporting legs are mechanically connected with the girders through rotary shafts, when the operation platform is lifted, the rotary supporting legs can rotate freely by 90 degrees, and an operator just needs to place the rotary supporting legs into reserved holes during installation. One end of each fixed supporting leg is welded and fixed to the corresponding girder, the other end of each fixed supporting leg is connected with a reserved steel bar, and in the lifting process, the fixed supporting legs are cut off the reserved steel bars. The hanging rings are formed by bending steel bars and welded to the girders. The formwork is laid on the girders. According to the elevator shaft standard operation platform and the implementation method, standard manufacturing of the elevator shaft operation platform is achieved, overall installation is convenient and fast, the problems that the erection efficiency of a scaffold in an elevator liftway is low, the material turnover cycle is long can be effectively solved, the construction cost is reduced, and construction safety is guaranteed.
