Beschreibung
Zusammenfassung:	The invention discloses a large base cross groove connecting device. The large base cross groove connecting device comprises an upper flange structure, a lower flange structure and a connecting piece. The upper flange structure and the lower flange structure are connected in a butt joint mode through the connecting piece and are installed, and flanges in the upper flange structure and flanges in the lower flange structure are crossed in a paired cross-shaped mode, and the flanges are provided with arc-shaped or line-shaped long holes. According to the large base cross groove connecting device, the upper flange structure and the lower flange structure can be installed in a counterpoint mode very conveniently and fast, the installation difficulty caused by manufacture errors can be effectively avoided, and construction equipment or tools with a plurality of large bases can be installed under the outdoor complex working conditions through the large base cross groove connecting device.
