The utility model discloses a civil wing root large-size wallboard butt joint structure test device. The test device comprises a test piece, a supporting part and two connecting assemblies. The test piece has an outer wing sidewall panel and a center wing sidewall panel. The two connecting assemblies are respectively clamped on an outer wing side wall plate and a central wing side wall plate of the test piece and are respectively connected to two chucks of a testing machine. The supporting component is supported on any connecting assembly so that the two connecting assemblies can be leveled. According to the test device, the supporting part is additionally arranged, the connecting assemblies on the two sides can be leveled, the influence of gaps and assembly errors on the test is reduced, and the loading centering performance of a large-size test piece is guaranteed. According to the invention, the problems of misalignment and uneven stress distribution in the test process of the large-size wallboard butt joi
