Through the six groups of aerated concrete plate four-point loading node ultimate bearing capacity test carried out at the steel pipe anchor node,sleeve node and the new F-type node,the node strength,node stiffness and other performance indi-cators of the three kinds of nodes under different plate thickness were analyzed.The study shows that the mechanical properties of the new F-type node are good,the connection is reliable,and the node ultimate bearing capacity increase with the increase of plate thickness.The new F-type node can be better applied in the aerated concrete composite thermal insulation exterior wall pan-el system.
