Aluminum alloy attached lifting operation safety protection platform for building construction (referred to as "aluminum alloy climbing frame") refers to the frame made of high-strength aluminum alloy materials set up at a certain height and attached to the building structure. The frame body can gradually climb or descend with the building structure depending on its own lifting equipment and device. It is a construction with safety protection, anti tilting, anti falling and synchronous lifting Operation platform.

    Aluminum alloy climbing frame body is composed of platform structure, lifting mechanism, power equipment, anti tilting device, anti falling device and lifting synchronous control system. The platform structure is composed of vertical main frame, horizontal supporting structure and platform frame.

    Compared with the traditional scaffold, aluminum alloy climbing frame has many advantages, such as saving materials, saving labor, strong independence, shortening the construction period, safe and reliable, fire and dust prevention and significant economic benefits. At the same time, compared with the steel climbing frame, it also has the advantages of lightweight material, higher construction efficiency, corrosion resistance, low maintenance cost, energy-saving and environmental protection, strong recyclability, small impact on the structure and strong safety.

    According to the statistics of relevant institutions, among the 150000 high-rise buildings constructed each year, less than 100000 of them need to use climbing equipment. According to the statistics of China formwork and scaffold Association, by the end of 2019, the stock of steel climbing frames in China's market is about 25000 (about 3600000 linear meters, 900000 machine positions), accounting for about 25% of the scaffold market scale.

    If half of the steel climbing frame in the current market is replaced by aluminum alloy climbing frame, it will bring 340000 tons of aluminum consumption (about 190kg aluminum per linear meter of aluminum alloy climbing frame). From the perspective of market scale alone, the future available amount will be more than 3.4 million tons, and the annual sales market scale of aluminum alloy climbing frame will reach 100 billion level. In terms of technology and environmental protection, aluminum alloy climbing frame will have a bright future if it can realize large-scale popularization and application of low-carbon emission reduction and green construction technology requirements.
