Construction method of self-stabilized internal and external sliding and moving type elevator shaft safety protection device

Abstract

The invention relates to a construction method of a self-stabilized internal and external sliding and moving type elevator shaft safety protection device. The construction method of the self-stabilized internal and external sliding and moving type elevator shaft safety protection device is characterized in that the self-stabilized internal and external sliding and moving type elevator shaft safetyprotection device comprises a cantilever frame, a sliding platform and a protection mechanism, wherein the cantilever frame comprises a main beam, a secondary beam, a limit beam, a vertical rod and atransverse beam, the vertical rod is provided with a leveling steel plate, the sliding platform comprises a main frame, a side frame, a main steel plate and a side steel plate, and the protection mechanism comprises a hanging net screw and a safety net; and the construction method comprises the steps that a cantilever beam is assembled and site-lifted, the leveling steel plate is adjusted, the sliding platform is mounted and slides into an elevator shaft, and the hanging net screw and the safety net are mounted. According to the construction method of the self-stabilized internal and externalsliding and moving type elevator shaft safety protection device, self-stabilized performance of the structure is high, operation in the shaft is less, construction safety is good, the turnover usingrate is high, dismounting is fast, and performance of energy conservation and environmental protection is good, the problems of complicated process, large on-site operational quantities, dangerous dismounting, low repeating utilization rate and slow construction progress of the conventional pre-embedded steel pipe protection technology are solved, and remarkable economic and social benefits are provided.

Description

technical field [0001] The invention relates to a construction method of a self-stabilizing internal and external sliding safety protection device in an elevator shaft, belongs to the field of construction engineering, and is suitable for safety protection in an elevator shaft. Background technique [0002] In recent years, with the rapid development of my country's urban and rural construction, the scale of the construction market has continued to expand, and high-rise and super high-rise buildings have become more and more common. During the construction of high-rise buildings, the protection of the entrance of the elevator shaft is the focus of safety protection on the construction site, and it is also a high-incidence area for safety accidents caused by falling from heights. The current routine practice at the construction site is: the elevator hole is buried with horizontal steel pipes, and the surface is covered with scaffolding or wooden formwork, as a hard level seal...
