Fabricated house structure

The invention relates to the technical field of fabricated buildings, and provides a fabricated building structure which comprises a cushion layer, a foundation, a prefabricated wall and a roof. The roof comprises a top floor slab and a windproof device. The windproof device comprises a shielding assembly, the shielding assembly comprises a plurality of sliding rods and a plurality of shielding parts, one end of each sliding rod is arranged on the top floor in a sliding mode, and the other end of each sliding rod is arranged on the prefabricated wall in a sliding mode. The shielding parts are connected to the two adjacent sliding rods. The windproof device has a windproof state in which the multiple sliding rods drive the multiple shielding parts to move to enable every two adjacent shielding parts to form a wind unloading angle opposite to incoming wind so as to prevent wind and an exposure state in which the multiple sliding rods drive the multiple shielding parts to be folded.
