Construction and Application of Oveelong Outrigger

There are many overlong cantilever components in the roof of public building at the present.Supporting frame design and the selection of scheme is the common technical issues in the project constructions.Building A of Beijing Jing An apartment engineering is a total of 14 stories,the height of top story is 4.2m,there are structural overhanging board outside of shear wall in the top story,the length together is 11m,and the cantilever width is 3.8m.The cantilever scaffold consist of steel tube fastener was used in the project.Design and checking computation is the first during construction,and taking a series measures to ensure the construction quality and safety,and has achieved good results.
