Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method of an adjustable elevator shaft operation platform. Background Art

[0002] At construction sites, accidents caused by falling objects and being hit in elevator shafts are frequent. The main reason is that the operating platforms in the elevator shafts are not unified, the frames are not standardized, and the protection is not in place. In particular, the elevator shaft frames on the working floor are crucial. There are two traditional ways to set up frames in elevator shafts. One is to use a floor-standing scaffolding, and the other is to use cantilevered I-beams to set up steel pipe operating scaffolding. Especially for the machine room-free layer, when the roof is a steel structure roof, the elevator shaft frame is set up at a high height, the construction is labor-intensive and material-intensive, and the safety is poor. The horizontal protection of the steel pipe scaffolding cannot be done very strictly, and there is still a risk of falling from a height and being hit by objects. The traditional elevator shaft steel pipe scaffolding operating platform can no longer meet the construction needs. Summary of the invention
