Study on influence of insulation anchor on thermal performance of external insulation single-sided superimposed shear wall
In order to study the influence of insulation anchors on the thermal performance of external insulation single-sided superimposed shear walls,the finite element software ABAQUS was used to compare and analyze the thermal performance of external insulation single-sided superimposed shear walls without insulation anchors,with stainless steel insulation anchors,with FRP insulation anchors and with steel-fiber composite insulation anchors.The results show that the average heat transfer coefficients of walls with stainless steel insulation anchors,FRP insulation anchors and steel-fiber composite insulation anchors are 15.9%,0.4%and 8.6%higher than those of walls without insulation anchors,respectively.The average heat transfer coefficient and the proportion of thermal bridge influence area increase with the decrease of insulation anchor spacing and the increase of insulation anchor diameter,which leads to the decrease of insulation performance.For stainless steel insulation anchors with large heat transfer coefficient,FRP can reduce heat transfer and effectively reduce thermal bridge effect.
