At present, steel scaffolding is basically used in high-altitude construction in China. It is a substitute for traditional bamboo scaffolding before the liberation of China. It has been developed for more than 80 years.
Scaffolding made of steel pipe materials in China now includes fastener steel pipe scaffolding, bowl-buckle steel pipe scaffolding, socket steel pipe scaffolding, portal scaffolding, and various inner scaffolding, hanging scaffolding and other steel pipe scaffolding. Starting from its material and structure, it is gradually divided into the following roughly:
Divided by the material of the rod
1) Scaffolding of single-size steel pipe. It only uses steel pipes of one specification, such as fastener-type steel pipe scaffolding, and only uses electric welded steel pipes of Ф48×3.5.
2) Scaffolding combined with various specifications of steel pipes. It is composed of more than two steel pipes of different specifications, such as portal scaffolding.
3) Scaffolding mainly made of steel pipes. That is, the scaffolding composed mainly of steel pipes and supplemented by other steel rods, such as inner scaffolds equipped with channel steel top brackets or bases, and scaffolds connected to steel plates. , Construction pipe, usually used to make brackets on construction sites, is a product made from hot-rolled strip steel after processing. In modern construction sites, rack tubes have been widely used, and you can see them everywhere. In recent years, after the rapid development of urbanization, the demand for rack tubes has increased. At the same time, the country has also introduced some measures to encourage the development of the shelf tube industry. Among them, the focus is on the development of shelf pipes in construction engineering. The shelf tubes used in building construction require a variety of varieties and a wide range of options. Therefore, rack tube manufacturers have accelerated the pace of reorganization to reset the leading edge of rack tube companies in the market.
The operation and management of the enterprise has been transformed from the single-target development in the past to the scientific and unified management. The formation of commercial concrete pumping cast-in-place reinforced concrete structures has promoted the application of formwork supports with high space and large span. The organization of formwork supports and high-rise scaffolding has become more and more in the construction of projects. obvious. And because of its simple and reasonable structure, perfect design, convenient use, safe, fast, easy to transport, store, and simple to maintain. Therefore, three firsts were achieved in the development history of the shelf tube at that time:
The first "realizes no moving parts on the shelf tube;
The first one" realized the independent intellectual property rights to the overall new rack tube
Scaffolding bowl side. Until now, the product has been welcomed by users at home and abroad, and is favored by domestic road and bridge, municipal, housing construction and other units. According to the report of the Association of Management Pipeline, when the steel pipe crossbar is used, the buckle steel pipe scaffold is a "single steel pipe scaffolding", and when the section steel crossbar is used, it is a "steel-based scaffolding".
These worlds have begun to gradually use aluminum alloy scaffolding, and because the traditional steel pipe scaffolding is too bulky and the installation efficiency of workers is low, the construction cost has increased significantly. Instead of traditional steel tube scaffolding, aluminum alloy scaffolding has its own scientific design, rapid construction and disassembly, light weight, stability, and safety, which is greatly improved compared to traditional steel tube scaffolding. Therefore, a part of the scaffolding industry will be replaced by steel tube scaffolding by bamboo before liberation, and the current steel tube scaffolding will be replaced by aluminum alloy scaffolding, which is the historical trend of future development.
