The present invention pertains to a framework connecting device of a prefabricated building structure. Each connection portion of frameworks (12), which are formed in the shape of a rectangular pipe so as to form columns, rafters or the like, is connected and fixed by front and rear connection pieces (14), (16) and a plurality of bolts (18) and nuts (20) which penetrate the same, wherein, during assembly, the frameworks (12) and the front and rear connection pieces (14), (16) are coupled by indented grooves (22) and protrusion portions (38), (40); base protrusions (30), (32) of the front and rear connection pieces (14), (16) are supported by the frameworks (12); and one or more support pipes (50) which are respectively connected and fixed by the bolts (19) and nuts (21) are provided between the front and rear connection pieces (14), (16). Therefore, the assembling work may be readily carried out in a short time while the strength of the connection portions may be reinforced. |
