Nowadays, people are more and more high to the aesthetic feeling of building, for making the building have aesthetic feeling and differentiation more, the designer often can design partial steel construction on the concrete roof to show the unique molding of building. Simultaneously, for making steel construction part more pleasing to the eye, avoid the steel and the different materials of outer curtain wall to demonstrate the sense of splitting in the vision and protect the steel not by erosion such as rainwater, the designer also can design the curtain on the steel construction.
In actual construction, a plurality of operation platforms can be used for constructing the outer curtain wall, such as scaffolds, construction hanging baskets and the like. For high-rise buildings, the construction period and the cost are comprehensively considered, and a construction hanging basket is often selected and used finally.
Each construction hanging basket comprises 2 hanging mechanisms, 1 hanging platform, a balance weight, a lifting machine, an electric box, an electric control system and other main parts. Wherein, the suspension platform is a suspension closed frame device which is provided with guardrails around and is used for bearing operating personnel and tools to carry out high-altitude operation; the suspension mechanism is a device which is erected above a building (structure) and suspends the platform through a steel wire rope; the counterweight generally adopts concrete blocks, and the counterweight of each construction hanging basket is generally more than 1000 kg.
