Abstract


With the increasing development of urban construction , in order to meet the requirements of the building versatility and handsome in appearance , a variety of conventional concrete structures is increasing. Typically covers an area of special concrete structure , spatial span and dead weight are great, so that as the the templates support of scaffolding erection construction span height , and when the the upper concrete structure strength has not yet formed , the support frame while undertake the construction of the concrete structure of various loads , higher requirements for the design and construction of the support frame . In recent years, a lot of construction scaffolding collapse accident , causing significant economic losses and casualties . Scaffolding fastener connection , erection methods belong to the structural instability system . This has resulted in the design theory and specification with the actual construction divorced from greater access to design conditions , design and construction of touch . Plus aspects of construction management and the quality of the materials , the main reason for the high incidence of scaffolding accident . Therefore , the correct specification of the design of scaffolding support frame become a top priority to develop a new kind of ultra-high span . This paper first reviews the the scaffold technology development in China , scaffolding classification . Then compare the steel frame , bent , hinged system computing theory , determine the problem of the calculation of the length of the various connection conditions . The papers also study the contrast the scaffolding design norms at home and abroad , that the domestic scaffolding specification and detailed design of parts on the inadequacies of the load value . Finally, a detailed description of the geometry and structural features of a new type of scaffolding , and general-purpose finite element software ANSYS analysis of the bending stiffness and ultimate bearing capacity of the nodes . With the structure of an engineering analysis of the carrying capacity of the scaffolding , the by scaffolding bearing capacity analysis , analyzed the new scaffolding is safe and reliable , has a higher carrying capacity than the original fasteners scaffolding .
