Design And Research Of High-altitude Steel Platform Steel Tube Scaffolding Support Structure

With the development of China's economic modernization, more and more large buildings which use the steel tube scaffolding supporting structure of high-level and large area are found in large and medium-sized cities. With the scale becoming larger and larger,the requirements of stiffness, strength, stability become higher and higher. In recent years,because the the steel tube scaffolding supporting structure of high-level and large area have the characteristics of complexity ,diversity , high-risk and Sudden accident, accidents which are caused by collapse of structure of high-level and large area are increasing . It brings us casualties and economic losses. So people began to search and research a new type of scaffolding structure toimprove the overall stability of scaffolding support structure. However, we still stay in the initial stage of the research, there is no relatively mature theoretical basis and experimental basis .Based on the large number of domestic and international reference literature ,we design and research high-altitude steel platform steel tube scaffolding support structure. This structures is to build the steel platform which is made up of many steel girders in the air, and then erect the scaffolding directly on the steel platform. It reduces the height of the scaffolding,improves the stability, insures the quality and safety of the structure construction . But now the most prominent issue has became the stability of the steel platform.This paper summarizes the background of the support system, the type of scaffolding and requirements of constitution, elaborate basic principles of the finite theory on the par, analyse of the scaffolding and steel platform stability combined with ANSYS. The research work has a theoretical significance and engineering value to the application of the high rise steel tube scaffolding support structure .
