Abstract


With the highly development of urban and rural economy,high form work support system has been more and more extensively applied to the cast-in-place concrete structure,and its consumption is the largest,its application is the widest in all form of formwork-supports at present in our country. But because some uncertain,unsafe factors exist in calculation of structural design and set up the frame in practice,caused the collapse of high-formwork-supports with couplers happened again and again,influenced the safety of construction and the use of building seriously. So,its stability capacity is a question which need urgently to solve.Firstly,the dissertation concluded the study fruit of scaffold and falsework both at home and aboard,which is very useful for the following study and reviewed the development process and the trend of scaffold in our country. In particularly,introduced the structure of the fasten-style tubular steel scaffolding. Then,enumerated the safety accidents of scaffolds in recent years and analyzed the reasons which cause these accidents,concluded the means to avoid the happening of these accidents. At last, introduced the main computation model a method of the falsework.From these analysis results,the author drew conclusions which are very useful to understand the mechanical capacity of the falsework system and guide the engineering practice.
