Study On Stability And Mechanical Properties Of New Attached Aluminum Alloy Scaffold

As a new type of alloy lifting scaffold,the main function of the attached aluminum alloy scaffold is to provide a safe and convenient construction platform for high-rise and super high-rise buildings.Because of its light weight,stable structure,high construction efficiency,more recycling times and good corrosion resistance,it is gradually replacing the position of all-steel attached lifting scaffold in the construction process.At present,the main research on the attached aluminum alloy scaffold at home and abroad still stays on its supporting components and main connecting components.The research on its safety performance and intelligent management is also in its infancy.There are few studies on the overall mechanical properties of the attached aluminum alloy scaffold and the safety performance of the scaffold under various working conditions.In view of the above content,the main research contents of this thesis are as follows :(1)Firstly,the bearing capacity of the lifting parts,the scaffold,the wall support and the vertical rod under the aluminum alloy is calculated,and the finite element simulation analysis of the above components under the same working conditions is carried out,and the simulated bearing capacity and deformation of the single component are obtained.The mechanical properties of the aluminum alloy lower lifting parts and the attached wall support were tested,and the anti-falling test of the attached aluminum alloy scaffold was carried out.The deformation of the lower lifting parts and the attached wall support under different working conditions was obtained,and the reliability and safety of the anti-falling device were determined.By comparing the theoretical calculation results,experimental results and finite element simulation results,the correctness of the finite element modeling is determined.The results show that the finite element software can better simulate the deformation and stress of the attached aluminum alloy scaffold under various working conditions.(2)Using BIM software Revit and CAD software Solid Works instead of the finite element software ANSYS for three-dimensional modeling.Using Revit ’s powerful 3D modeling ability and excellent visualization effect to achieve the effect of rapid modeling;using the crack inspection and material change function of Solid Works,the component cracks that are easy to appear in the modeling are improved and the material update of the model is completed,which makes up for the defect that the inspection function of ANSYS is not perfect,and provides a new idea for the establishment of complex threedimensional model.(3)The results show that the wind load is the most important factor affecting the safety performance of the attached aluminum alloy scaffold.The finite element simulation of the bearing capacity and deformation of the attached aluminum alloy scaffold under different working conditions was carried out by ANSYS.The construction synchronization simulation of the formwork project,the unloading platform and the hanging basket project that can be synchronously constructed with the attached aluminum alloy scaffold is carried out.It is determined that the most critical part of the synchronous construction is the connecting member of the two,and the template project and the attached aluminum alloy scaffold are synchronized.The construction suitability is the best,the unloading platform and the hanging basket are less compatible with the synchronous construction of the attached aluminum alloy scaffold,and the synchronous construction is more difficult.
