Constructing method for high-rise building elevator shaft through elevating type safety protection steel platform

Abstract

The invention discloses a constructing method for a high-rise building elevator shaft through an elevating type safety protection steel platform, comprising the steps of: firstly, manufacturing a steel platform matched with the size of an elevator shaft, then installing the steel platform inside the bottom layer of the elevator shaft, carrying out elevator shaft construction operation by constructors standing on the steel platform, elevating the steel platform layer by layer after the construction on the current operation layer is completed until the steel platform is elevated to the elevator shaft of the upper floor to facilitate the elevator shaft construction operation, sealing the lower elevator shaft after the steel platform is elevated, and repeating the steps until the elevator shaft construction on all the floors of the whole building is completed. The construction method is featured by safety, simplicity and convenience for operation, easiness for construction, obvious economic benefits and the like, has the greatest advantages of saving lease expense of raw materials and facilitating cost control, and is particularly suitable for high-rise buildings and multistoried buildings with longer construction periods.

Description

technical field [0001] The invention relates to a building construction method, in particular to a safety protection construction method for an elevator shaft of a high-rise building and an elevator shaft of a multi-storey building with a long construction period. Background technique [0002] In the process of high-rise building construction, the fall prevention of the elevator shaft of high-rise buildings is an important check point and control point for safety management in building construction. How to ensure the safety and economy of high-rise building elevator shaft construction is a very important technical problem. Generally, the construction in the elevator shaft of high-rise buildings is erected from bottom to top with steel pipe scaffolding. The construction personnel stand on the scaffolding to carry out the construction work of the elevator shaft, and use steel wire ropes to unload in the middle, usually once every 5 floors. The disadvantages of this method are...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: (1) Due to the mechanical bearing capacity of the steel pipe itself, when the height of the frame exceeds 50m, the stability of the frame is not firm, and there are certain safety hazards

(2) Generally, the construction period of high-rise buildings is long, and steel pipes are mostly leased. The steel pipe materials take a long time, and the rent of steel pipes is relatively large, which is not conducive to saving project costs.

(3) It is cumbersome and time-consuming to set up scaffolding, which virtually prolongs the construction period
