This utility model provides an external wall fixing node and an external wall fixing structure. The external wall fixing node is applied to an external wall structure and includes: a connecting structure forming a first cavity, used for fixing to a wall panel of the external wall structure; a connecting plate including a connecting body and a fixing support plate extending from the connecting body, the fixing support plate extending into the first cavity; and a
gasket having a slot, the
gasket being fitted onto the outside of the fixing support plate through the slot, and the
gasket being located within the first cavity. The gasket includes various types, with each type of gasket having the same size as the first cavity in a first direction, and the spacing between the slot and the edge of the gasket differing in the first direction. This external wall fixing node can meet the spacing requirements of wall panels and walls in different external wall structures and can also reduce the risk of
assembly interference.
