Deck framework for reinforcing PCTC ship cabin

The invention relates to the technical field of PCTC ships, in particular to a deck framework for reinforcing a PCTC ship cabin, which comprises deck main longitudinal girders and short cross beams, the deck main longitudinal girders are connected to the main cross beams, a plurality of groups of main cross beams are arranged at equal intervals, and a first deck auxiliary longitudinal girder and a second deck auxiliary longitudinal girder are connected through a triangular plate. The triangular plate can further transversely connect and reinforce the first deck auxiliary longitudinal girder and the second deck auxiliary longitudinal girder which are connected to the main cross beam by means of the characteristic that a triangle has stability. Meanwhile, the reinforcing assemblies which are encircled into a triangular shape are convenient for tightening the longitudinal connection relationship between two adjacent groups of first bearing plates and two adjacent groups of second bearing plates at the bottoms of
