Connection node structure of fair-faced concrete prefabrication exterior wall hanging plates

The invention discloses a connection node structure of fair-faced concrete prefabrication exterior wall hanging plates. The connection node structure comprises first connection angle iron, second connection angle iron and a support bolt; the first connection angle iron is fixed with an embedded base in a main body frame structure in a welding mode, the first connection angle iron and the second connection angle iron are each provided with a long-strip-shaped through hole, the support bolt is arranged on the first connection angle iron and used for supporting a lower bracket of the upper exterior wall hanging plates located above the support bolt, the first connection angle iron is fixedly connected with the second connection angle iron through a first connecting bolt, and the horizontal edge of the second connection angle iron is fixed with an embedded nut located in an upper bracket of the lower exterior wall hanging plate located below the second connection angle iron through a second connecting bolt. According to the connection node structure of the fair-faced concrete prefabrication exterior wall hanging plates, connection is convenient, and a certain displacement can be generated in the up and down direction and the left and right direction to prevent the exterior wall hanging plates from being damaged and disengaged when the connection node structure bears too large loads.
