Concrete is poured into the steel formwork column, the steel formwork beam 1 and the shear wall 10. A steel formwork column includes an internal hollow internode column 2 and two internal hollow standard nodes 3, and the length of the standard node 3 is less than the length of the internode column 2. The upper and lower ends of the standard node 3 are fixedly arranged with end ring plates 4, and the end ring plates 4 are provided with pouring holes 41 for pouring concrete. The two standard nodes 3 are respectively fixedly arranged at the upper and lower ends of the internode column 2 through the end ring plates 4, and the internal spaces of the standard nodes 3 and the internode column 2 are connected, and the cross-sectional shapes of the internode column 2 and the standard nodes 3 are the same.

[0027] Reference Figure 1, there are 4 shear wall structures, including 1 cross-shaped shear wall structure, 1 T-shaped shear wall structure and two L-shaped shear wall structures. Each shear wall structure is connected by a steel membrane shell beam 1 to form a rectangular frame structure. A steel formwork shell beam 1 is fixedly connected between the standard sections 3 at the upper ends of two adjacent shear wall structures, and a steel formwork shell beam 1 is fixedly connected between the standard sections 3 at the lower ends of two adjacent shear wall structures. The cross-shaped shear wall structure includes a shear wall 10, a steel formwork shell column with a cross-shaped cross section, and a steel formwork shell column with a straight cross section. The steel formwork shell column with a cross-shaped cross section is welded and fixed to one side of the shear wall, and the steel formwork shell column with a straight cross section is welded and fixed to the other side of the shear wall. The T-shaped shear wall structure includes a shear wall 10, a steel formwork column with a T-shaped cross section, and a steel formwork column with a straight cross section. The steel formwork column with a T-shaped cross section is welded and fixed to one side of the shear wall, and the steel formwork column with a straight cross section is welded and fixed to the other side of the shear wall. The L-shaped shear wall structure includes a shear wall 10, a steel formwork column with an L-shaped cross section, and a steel formwork column with a straight cross section. The steel formwork column with an L-shaped cross section is welded and fixed to one side of the shear wall, and the steel formwork column with a straight cross section is welded and fixed to the other side of the shear wall.

[0028] Continue to refer to Figure 1 , the two ends of the steel formwork beam 1 are fixedly connected to the standard section 3 of the shear wall structure, and the two ends of the steel formwork beam 1 are respectively fixed at the middle position of the vertical direction of the corresponding side wall of the corresponding standard section 3. In this embodiment, the height of the preferred standard section 3 is 80 cm, and the height of the steel formwork beam 1 is 40 cm. After the steel formwork beam 1 is fixed on the corresponding side wall of the standard section 3, the distance from the upper surface of the steel formwork beam 1 to the upper surface of the standard section 3 is 20 cm, and the distance from the lower surface of the steel formwork beam 1 to the lower surface of the standard section 3 is 20 cm. Two stiffening plates 11 coplanar with the upper and lower surfaces of the steel formwork beam 1 are welded on the inner wall surface of the standard section 3, and a through hole for concrete circulation is formed between the side surface of the stiffening plate 11 away from the corresponding side wall and the opposite side wall of the corresponding side wall of the standard section 3.

[0030] The implementation principle of Example 1 of the present application is as follows: the steel formwork concrete composite structure system of the present application fixes and combines the shear wall 10 and the steel formwork column into a shear wall structure, increases the total load-bearing surface of the steel formwork column, and then connects the shear wall structures through the steel membrane shell beam to form a building frame, which greatly improves the structural strength and load-bearing capacity of the frame as a whole. Moreover, the steel formwork concrete composite structure system of the present application can prefabricate the internode column 2, the standard section 3, the shear wall 10, and the steel formwork beam 1 in the factory in advance, and then transport them to the construction site for assembly construction and pouring concrete, which can greatly improve the efficiency of building construction and save costs. Dividing the steel formwork column into two parts, the internode column 2 and the standard section 3, is more convenient for transportation, and is also easier to hoist during construction and assembly. Moreover, the steel formwork concrete composite structure system of the present application has a large total load-bearing surface of the shear wall structure, but a relatively small thickness, which can make the thickness of the shear wall structure the same as the thickness of the ordinary wall, so that the shear wall structure can be hidden after the ordinary wall is set, thereby enhancing the unity of the indoor wall and enhancing the appearance effect.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
