An overall lifting method for unloading platform

Abstract

The invention discloses an integral lifting method for a discharging platform. The integral lifting method includes the steps: enabling the discharging platform to climb along an attached lifting scaffold under pulling of an auxiliary pull rope until the discharging platform is 50cm higher than a first floor plate, stopping climbing of the attached lifting scaffold and detaching a bracket from the discharging platform; continuing climbing of the discharging platform until the discharging platform is 50cm higher than a second floor plate, detachably and fixedly connecting the bracket with the discharging platform, disconnecting a stress rope and a safety rope from a third floor plate and fixing the stress rope and the safety rope to a fourth floor plate; enabling the discharging platform to descend along the attached lifting scaffold until the bracket is abutted to the second floor plate. By optimizing the lifting steps, the bracket contacts with a target floor to serve as a criterion of in-place lifting of the discharging platform, and the lifting efficiency of the discharging platform is greatly improved. In addition, safety of the discharging platform in the lifting process is further improved.

Description

technical field [0001] The invention relates to the technical field of construction of a discharge platform for construction engineering, in particular to an overall lifting method for a discharge platform. Background technique [0002] At present, the attached lifting scaffold is widely used as an external protective frame in the construction of construction projects. Most of the unloading platforms used in conjunction with the attached lifting scaffold are lifted and removed by tower cranes before the attached lifting scaffold climbs. Put it on the vacant site. After the attached lifting scaffold climbs into place, use the tower crane to lift the unloading platform to the installation position and fix it on the structure. This method takes a long time, occupies the site, and occupies the tower crane many times, affecting the construction of other processes. .

Problems solved by technology

[0002] At present, the attached lifting scaffold is widely used as an external protective frame in the construction of construction projects. Most of the unloading platforms used in conjunction with the attached lifting scaffold are lifted and removed by tower cranes before the attached lifting scaffold climbs. Put it on the vacant site. After the attached lifting scaffold climbs into place, use the tower crane to lift the unloading platform to the installation position and fix it on the structure. This method takes a long time, occupies the site, and occupies the tower crane many times, affecting the construction of other processes.

[0003] For this reason, an overall lifting method of the unloading platform has appeared in actual engineering construction. Specifically, the unloading platform is fixed on the attached lifting scaffold through a pull rope, and the unloading platform is quickly installed and disassembled before and after the attached lifting scaffold climbs. The unloading platform automatically follows the synchronous lifting of the attached lifting scaffold, but this method is to remove the cantilever beam connected to the unloading platform and the load-bearing rope connected to the main structure together before the unloading platform is lifted. When the platform is lifted with the attached lifting scaffold, it is often impossible to accurately lift it to the position corresponding to the target floor layer, and it needs to be adjusted several times before it can be in place
