Description

Technical Field

[0001] The utility model relates to a construction platform for reverse hoisting the roof bottom plate of a steel structure factory building, belonging to the field of steel structures. Background Technique

[0002] The existing construction methods for transporting materials at high altitude during steel structure construction generally include manual handling, which is applicable to the transportation of small materials. However, there are safety hazards in the process of manual handling during cross-construction up and down. Using a lift for hoisting will increase the construction measure cost, limit the construction area, and have low efficiency. Erecting a full hall scaffold will increase the construction measure cost, and the installation, disassembly, and approval process of the full hall scaffold is cumbersome and requires demonstration, etc.

[0003] In view of the current construction situation of difficult reverse hoisting and installation of the bottom plate in the steel structure roof enclosure system, a series of studies have been carried out on the reverse hoisting and installation technology of the bottom plate during the construction of steel structure roof panels. This application has developed an auxiliary lifting system that is convenient for movement and ensures safety and quality, which can well solve construction problems such as difficulty in centralized installation of a large amount of materials, slow up and down material transportation, inability to meet the scaffold erection and flexible translation due to uneven ground, and high risk coefficient for personnel working at high altitude.
