Bowl-buckle scaffold support?

At present, bowl scaffold is widely used as support in the bridge formwork support system in China, but heavy casualties caused by the collapse of bridge formwork support frame occur from time to time. The approach bridge of Kunming new airport just collapsed, killing 7 people and injuring 34 others. Bowl-buckle scaffold is used as the supporting system in the construction. It is precisely because of the constant occurrence of these accidents that some experts have written an article, classifying the bowl-button scaffold as a scaffold system that needs to be eliminated, and blaming these major accidents on the reliability of the bowl-button scaffold system. This is a wrong understanding.

Bowl-button scaffold was first developed by SGB Company in England in 1976. Once introduced, the system has been rapidly popularized in many countries in the world because of its irreplaceable advantages. After more than 30 years of practical application abroad, it has been proved to be a very mature and excellent product. Its mechanical design and process design make the system not only suitable for scaffolding field, but also suitable for heavy-duty support field. In terms of specific product specifications, vertical poles are designed with different wall thicknesses. For the specifications applied to the support, the design of increasing the wall thickness and the standard load of single limb safety is adopted. Bowl-button scaffolding still accounts for 50%-60% of the system scaffolding exported by our company to the United States, and a large part of it is relatively heavy, which is used for formwork support or scaffolding industrial application with relatively large load.

Bowl-buckle scaffold is one of the systems introduced earlier in China. According to reports, it was revised by the professional design institute of the Ministry of Railways on the basis of the original design of 1986 SGB company, and it has also been widely popularized and applied in China. However, judging from the domestic application effect, the performance is very poor. Many bridge formwork supports collapsed, causing heavy casualties. Bowl-button scaffolding was indeed used. Why is this? With this problem, the author has conducted many investigations on some bridge construction sites using bowl-shaped scaffolding, and found that compared with the original design of SGB, the bowl-shaped scaffolding currently used in China has been modified beyond recognition intentionally or unintentionally. Whether it is the manufacturing process of products, site erection and construction safety management, or the modification and wrong positioning of the original design in technical specifications, the safety of bowl-buckle scaffolding applied in Europe and America is very different. This bowl buckle rack is not the same bowl buckle rack. This is also one of the important reasons why domestic accidents occur frequently, and what is used abroad is safe and stable.

Since 20 10, Henggong Formwork Company will introduce bowl-shaped scaffolding exported to the United States in China, and combine the practical application of bridge formwork support in China to launch its own patented bowl-shaped support system. Harsco, the parent company of British SGB, will gradually promote its bowl-button scaffolding in China. I hope these actions will have a positive impact on the scaffolding and formwork support industry in China.
