Assembly type stiff combination frame support structure

The invention discloses an assembly type stiff combination frame support structure. The assembly type stiff combination frame support structure comprises a cross beam and stand columns fixedly connected with the cross beam, wherein frame supports are fixed to the joints between the cross beam and the stand columns. The cross beam is prefabricated by combining reinforced concrete and section steel. The two ends of the cross beam are provided with cross beam H-shaped steel, wherein the cross beam H-shaped steel is fixedly connected with stand column H-shaped steel fixed to the stand columns. Stand column external claddings are arranged outside the stand columns. The assembly type stiff combination frame support structure is simple in structure and convenient to construct; prefabricating combination and cast-in-place are mutually combined, so that construction cost is reduced, construction progress is accelerated, and the stability of a architectural structure is also enhanced; particularly, by the adoption of the hollow steel frame support, the span length of the beam is increased greatly, and the weight of a building is reduced at the same time; rapid assembly between the prefabricated concrete beam and the stand columns is realized, wherein the H-shaped steel is embedded in the two ends of the beam; steady combination between the beam and a floor slab is realized through connecting reinforcements.
