Mechanical Analysis Of Constraint Rope System In Hoisting Steel Reinforcement Cage

In recent years, with the large-span buildings and ultra-deep, ultra-highbuildings appeared, a growing number of large and even very large structure requireslifting. In order to lift this large-span buildings,the general practice is to be segmentedlifting and hanging pieces spliced directly in the field or pouring,so time-consumingand laborious, but also the integrity of the structure caused some impact. In order toguarantee the integrity of the structure two or even more lifting cranes was usedsimultaneously, which increases the difficulty of the operation, and this paper relatesto a stell cage structure is relatively complex. Compared with the hoisting of the largespan to members of reinforced cage integral stiffness is relatively small,research onhoisting this small Rigidity steel reinforcement cage have many shortcomings. But inreality the calculation of hanging large span component is disordered. Failed to reflectthe mechanical characteristics of the hoisting of constraint rope system,and there is abig difference in actual mechanical state. Therefore, such a large span of liftingcomponents are increasingly important.Based on the hoisting of the Diaphragm Wall of large steel reinforcement cageGreen Center towers, analysis the existence of its mechanics properties of thislarge-span structure and steel wire rope, pulley component constraint rope system.Bythe nature of the hanging itself and calculating the actual column to revise and perfectthe constraint rope system mechanics and optimizing the best position of hangingpoints.By calculating and analyzing the double-hoist four-point lifting to revisingcalculating method of the ideal position based on symmetry.This paper choose Several common constraint rope system to lift and analysissteel cage,Through comparative analysis of the reinforcement cage differentconstraint rope system, the advantages and disadvantages of several differentconstraint rope system has been worked out. It provides a valuable basis for us toselect the appropriate constraint rope system and make the force of the hanging andconstraint rope system more reasonable based on the nature of the hanging itself. Through getting the project center underground continuous wall largereinforcement cage’s equivalent stiffness,Comparative analysis the deformation ofstell cage lifting restrained rope system,getting the results of deformation in cagehoisting on the restrained rope system performance influence should not be neglect.
