Prefabricated wallboard and door opening lintel structure formed by same

The door opening lintel structure comprises wallboard bodies which can be spliced in sequence, U-shaped lifting hooks are embedded in the tops of the wallboard bodies, the door opening lintel structure further comprises a connecting piece, the connecting piece comprises a frame body and a limiting rod, the frame body is arranged on the U-shaped lifting hooks of the two adjacent wallboard bodies in a sleeved mode, and the limiting rod is arranged on the U-shaped lifting hooks of the two adjacent wallboard bodies in a sleeved mode. The limiting rod is detachably connected with the frame body, and the limiting rod penetrates into the U-shaped lifting hook. Two adjacent wallboard bodies can be quickly fixed by the aid of the connecting pieces, so that a plurality of wallboard bodies can be simultaneously lifted to mounting positions by a lifting device, construction efficiency is improved, and the wallboard bodies can be conveniently lifted to the mounting positions when cast-in-place beams are cast at the tops o
