The invention discloses a halved double-folding thermal-insulation landing door device. The halved double-folding thermal-insulation landing door device comprises an upper ridge assembly, a lower ridge assembly, a first door plate assembly, a second door plate assembly, a third door plate assembly and a fourth door plate assembly. The first door plate assembly, the second door plate assembly, thethird door plate assembly and the fourth door plate assembly are all provided with heat insulation bodies which are made of heat insulation materials. The first door plate assembly comprises a first heat insulation part and a second heat insulation part, the second door plate assembly comprises a third heat insulation part, and the free end of the third heat insulation part extends towards one side of the first heat insulation part. When the first door plate assembly is in an unfolded state relative to the second door plate assembly, part of the first heat insulation part is hooked with and inserted into the third heat insulation part, and a continuously-bent first heat insulation seam is formed between the first heat insulation part and the third heat insulation part. The second heat insulation part is correspondingly matched with the edge of the third door plate assembly so as to form a second heat insulation seam which is continuously bent in a step shape.
