Study on the mechanical performance of structural thermal insulation integrated wall non-removal formwork
With the release of green building policies in various provinces,the structural insulation inte-grated wall is difficult to meet the energy-saving target with high requirements,and the insulation layer with a thickness of more than 200mm has become one of the main ways to meet the energy-saving level in the future.This paper takes the actual project as a case study,and simulates under wind load through ANSYS finite element software.A comparative study on the stress of 220mm thick non-removable formwork in the frame-shear structure of the structural insulation integrated wall shows that when the thickness of the non-removable formwork increases and its dead weight increases,its deformation also increases multiple times.In addition,stress concentration is prone to occur at the junction of different components and the Yin and Yang Angle in high-rise build-ings,which is the vulnerable part of the non-removable formwork.The existing connectors can not meet the requirements of the use of non-disassembling formwork for the ultra-thick structural in-sulation integrated wall,and need to be improved according to the mechanical characteristics.
