As shown in Figs. 4 to 6, the assembled building structure further includes a plurality of profile steel beams 4 which are arranged at the upper end of the wall body structure 2 and are fixedly connected with the structure supporting steel pipes 3 in the prefabricated wall plates 1 so as to form a steel structure building together with the structure supporting steel pipes 3. To further improve the connecting stability between adjacent prefabricated wall plates 1, the profile steel beams 4 are bridged on the adjacent prefabricated wall plates 1 so as to connect the adjacent prefabricated wall plates 1 together. The profile steel beams are installed at the upper end of the wall body structure formed by assembling and connecting the prefabricated wall plates, and the profile steel beams are fixedly connected with the structure supporting steel pipes in the prefabricated wall plates to enable the profile steel beams and the structure supporting steel pipes to jointly form a steel structure framework used as a basic framework of an assembled house, significantly improving the bearing strength of the assembled house using the assembled building structure with combination of steel structure and concrete structure. Therefore, compared with a traditional assembled house, the assembled house adopting the assembled building structure with combination of steel structure and concrete structure may be built higher, and a modular building also may be applicable to the field of high-rise buildings. In addition, as the steel structure building jointly formed by the profile steel beams and the structure supporting pipes may effectively improve the overall bearing strength of the assembled house, the prefabricated wall plates of the assembled house adopting the assembled building structure with combination of steel structure and concrete structure may be made of a lighter material in comparison to the traditional assembled house.

The structure supporting steel pipes 3 are provided with up-down penetrating steel pipe vertical holes 32. The profile steel beams 4 are provided with steel beam vertical holes 43 communicated with the steel pipe vertical holes 32. The assembled building structure with combination of steel structure and concrete structure further includes a floor slab 5 mounted on the profile steel beams 4. Floor slab vertical holes 51 communicated with the steel beam vertical holes 43 are formed in the floor slab 5.
