Articulation test device for end part of anti-seismic node test piece and installation method thereof

The invention discloses a hinge test device for an end part of an anti-seismic node test piece and an installation method of the hinge test device. The test device comprises an end part embedded part, a pin shaft, a pin shaft connecting piece, an iron wedge, a connecting beam, a reaction frame cross beam connecting piece and a gasket. The end embedded part and the node test piece are poured or welded into a whole, the hinge pin connecting piece and the end embedded part form a hinge device through the hinge pin, and then the hinge device is connected with the reaction frame through the connecting beam and the reaction frame cross beam connecting piece. Wherein the iron wedge can increase the compatibility when the end part of the test piece is not collinear with the test device in the mounting process; the horizontal and vertical linear displacement of the end part of the test piece can be restrained, but the rotation of the end part of the test piece is not limited, and the boundary condition of hinging the
