Abstract

The invention discloses a production method of a steel panel concrete structure with an internal truss support system. The production method comprises the following steps: (1) machining vertical internal truss supports and horizontal internal truss supports; (2) connecting two steel panels through the vertical internal truss supports and the horizontal internal truss supports; (3) mounting studs and shear reinforcement to form a plurality of submodules; (4) splicing the submodules to form an integral module; (5) lifting the integral module to a proper position, and pouring concrete between the steel panels. The vertical internal truss supports and the horizontal internal truss supports are used for providing rigidity not only in the submodule producing stage, but also in the splicing and mounting stages of the steel panel concrete structure. Therefore, the construction deformation and stability of the large-scale module are controlled, and planer external shear capability of the steel panel concrete structure after concrete pouring is higher than that of the conventional planer external shear reinforcement.
