ALC plate connecting structure

The utility model relates to the technical field of constructional engineering, in particular to an ALC (autoclaved lightweight concrete) plate connecting structure, which comprises a structural plate, the ALC plates are installed at the bottom of the structural plate, a connecting piece is arranged between each ALC plate and the structural plate, a connecting pipe is arranged at one end of each connecting piece, the connecting pipes are fixedly connected to the ALC plates, fasteners are fixedly connected between the connecting pieces and the structural plate, and the fasteners are fixedly connected to the ALC plates. A first mounting groove is formed in one end, close to one side face of the structural plate, of each ALC plate, a second mounting groove is formed in the other end, close to one side face of the structural plate, of each ALC plate, and when the two adjacent ALC plates are transversely attached, the first mounting grooves and the second mounting grooves are communicated and form connecting groov
