Force Analysis And Applied Research To Disc Type Steel Pipe Scaffold

Scaffolding is a new scaffold with disc inserted, it is safe and easy to use, suitable for all kinds of occasions, and it is not easy to damage, and has the advantages of low profits, is now the ideal construction of a type of scaffolding. As building complex jump space, ultimate bearing capacity and deformation of the contradictions of the scaffolding is highlighted, but the scaffolding was developed not for long, there are still many problems to be studied.Used General limited Yuan analysis software SAP and ANSYS on test in the of scaffolding system established three dimensional Rod Department calculation model, consider material of play plastic and the structure of geometry nonlinear, for nonlinear limit hosted force analysis; and respectively introduced turned spring and axis to spring unit simulation beam node half rigid and support and node of connection stiffness, through change spring unit of stiffness on whole structure for parameter analysis, get and test results more anastomosis of numerical analysis model. Comparative study on the numerical analysis and experimental results showed that supports connection stiffness to the structure of the ultimate bearing capacity of lateral stiffness and significant, but the effect of semi-rigid joints on a modest, simple, can be articulated joints.Considering the results of experimental research and finite element analysis, to improvement the scaffold node form design, Solidworks modeling software as a platform for implementation artifacts assembled set of modeling and structure.Through this study, experimental study on inserting scaffold model, we obtain the structure can withstand the maximum vertical downward force, able to withstand the maximum force on the horizontal direction, compared with traditional scaffolding, which is a distinct advantage. On failure forms of the scaffold, see damaged scaffold upper portion of buckling behavior of scaffolding and has no significant deformation in the lower half. Analysis of spring scaffolding as the connection, get the stiffness of the joints and gusset. By changing the stiffness of the spring, scaffolding analysis we obtain the maximum lateral stiffness and other basic data. To strengthen the original scaffolding, scaffold difficult situations have been improved, and use test disk plugged into scaffolding the overall stability and installation properties, specific parameters of scaffold by using finite element analysis of accurate measurements, was given concrete effect analysis of stiffness and improved.
