(57) The invention belongs to the technical field of structural engineering, and particularly discloses a steel prestressed concrete composite beam and a pouring mold thereof. The pouring mold comprises fixing plates, fixing sleeves, stabilizing rods and pouring sleeves. The two fixing plates extend into a concrete base. The two fixing sleeves are symmetrically arranged on the inner side of the fixing plate, and meanwhile the two stabilizing rods are symmetrically and obliquely arranged between the fixing plate and the fixing sleeves. The pouring sleeve comprises an internally-arranged pouring sleeve, an upper pouring sleeve and a cross beam pouring sleeve; the internally-arranged pouring sleeve penetrates through the fixing sleeve, and the top of the internally-arranged pouring sleeve extends out of the fixing sleeve; the upper pouring sleeve is connected with the top of the inner pouring sleeve, and bearing plates are arranged on the two sides of the upper pouring sleeve. And the cross beam pouring sleeve sleeves the outer side of the upper pouring sleeve and is positioned on the upper side of the bearing plate. According to the pouring mold, the vertically-placed fixing plate is fixed through the pouring groove in the concrete base, meanwhile, the fixing sleeve and the fixing plate are connected through the stabilizing rod, and the stability and construction safety of the base can be effectively improved.
