Multi-curved-surface arch-body building connecting system and construction method thereof

The invention discloses a multi-curved-surface arch-body building connecting system and a construction method thereof, and relates to the field of building construction. The multi-curved-surface arch-body building connecting system comprises a first arch body, a second arch body and a connecting arch wall, wherein covering edges are arranged at arch door holes of the first arch body and the secondarch body; a first adapter is in fixed connection with the covering edges; a first connecting steel passage is in connection with the outer side of the first adapter; first clamps are in connection with the inner side and the outer side of the first connecting steel passage. Two ends of the connecting arch wall are provided with glass arch bodies, and the glass arch bodies are clamped in the first clamps, so that the connecting arch wall is respectively in connection with the first arch body and the second arch body. The first arch body, the second arch body and the glass arch body of the system have smooth transitio
