Multi-layer pig house beam body structure

The utility model relates to the field of hog houses, in particular to a multi-layer hog house beam body structure which comprises a vertical bearing beam, a transverse bearing beam and a pedestrian path bearing beam. The at least four vertical bearing beams are vertically fixed to a foundation, one transverse bearing beam is fixed between every two adjacent vertical bearing beams, and the transverse bearing beams are perpendicular to the vertical bearing beams. The space defined by the vertical bearing beams and the transverse bearing beams corresponds to one breeding area. Each layer of pighouse is provided with a left column of breeding areas and a right column of breeding areas, pedestrian passageway bearing beams are arranged between the two columns of breeding areas, the pedestrianpassageway bearing beams are fixed to the vertical bearing beams, and the pedestrian passageway bearing beams are located below the transverse bearing beams. The pedestrian path bearing beams and thetransverse bearing beams ar
