AUTOMATIC EMPLACEMENT CONSTRUCTION METHODS OF LARGE SINGLE-LAYER PLANE CABLE NET CURTAIN WALL BASED ON FORM-FINDING ANALYSIS

Counterweight construction method, which is commonly used in installation of a large single-layer planecable net curtain wall, has lots of disadvantages． It is intended to present a new method to overcome theseshortcomings． The elastic deformation in the construction process of the vertical cable is deeply analyzed． Based onthe improved form-finding method with nonlinear inverse iteration that was proposed in preliminary study, anautomatic emplacement construction method for single-layer plane cable net curtain wall is brought forward． Theproposed method combines the principles and the fundamental purposes of the counterweight method, as well as thefeasibility of the construction site． This construction simulation-based method without counterweight can achieve thesame effect as the counterweight method, so as to save a lot of construction costs and reduce security risks． Thepractice applications show that the self-horizontal and self-vertical construction method can completely replace thecounterweight construction method, which has strong feasibility and significant superiority in application because it isa more economic, safer and simpler method．
