[0030] This invention proposes a modular steel building structure that addresses the technical problems of insufficient energy dissipation capacity and poor collaborative stress-bearing performance between existing modular steel building structures and their lateral resistance components. Two opposing integral shear walls are constructed on the two opposite gable walls of the main body of the modular steel building. The integral shear walls are subjected to continuous stress from top to bottom, effectively increasing the load transfer path in the modular steel building structure and efficiently transferring loads to the integral shear walls (energy-dissipating and vibration-damping structures), thus improving the overall energy dissipation capacity of the building structure. Simultaneously, the integral shear walls are embedded within the steel structural modules that make up the corresponding gable walls and are directly connected to the steel structural modules, improving the collaborative stress-bearing performance between the shear walls and the steel structural module units. This modular steel building has advantages such as simple structural composition, high overall seismic and wind resistance, and convenient construction.

[0031] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0032] Example 1:

[0033] Reference Figure 1 and Figure 2 This embodiment provides a modular steel building structure, including a first shear wall 1, a second shear wall 2, and a main building 3 composed of multiple stacked steel structure modules 31. The first shear wall 1 and the second shear wall 2 are arranged opposite each other on two gable walls of the main building 3. At the same time, the first shear wall 1 and the second shear wall 2 are both embedded in the steel structure modules 31 that make up the corresponding gable walls, that is, the first shear wall 1 and the second shear wall 2 are both installed on the steel structure modules 31.

[0034] Reference Figure 1The first shear wall 1 and the second shear wall 2 are identical structures, differing only in their location. These two shear walls are positioned opposite each other on the gable walls of the main building 3, facilitating their mutual cooperation in resisting torsion. The integral shear walls exhibit continuous vertical force distribution, effectively increasing the load transfer path in the modular steel building structure. This allows for efficient load transfer to the integral shear walls (energy-dissipating and vibration-damping structures), enhancing the overall energy dissipation capacity of the building structure. Simultaneously, the integral shear walls are embedded within the steel structural modules 31 that form the corresponding gable walls, directly connecting to them and improving the collaborative load-bearing performance between the shear walls and the steel structural modules 31. This modular steel building boasts advantages such as simple structural composition, high overall seismic and wind resistance, and convenient construction.

[0035] In addition to the connection between the shear wall in this application, the connection methods between other components of the steel structure modules 31 refer to the prior art and will not be described in detail here.

[0036] Reference Figure 1 and Figure 2 This embodiment provides a modular steel building structure. The first shear wall 1 and the second shear wall 2 have the same structure. The first shear wall 1 includes multiple first sub-walls 11 connected sequentially from top to bottom. Each first sub-wall 11 is embedded in one side wall of a steel structure module 31. By decomposing the first shear wall 1 into multiple first sub-walls 11 and then embedding each first sub-wall 11 in one side wall of a steel structure module 31, the coordinated load-bearing performance of the first shear wall 1 and the steel structure module 31 unit is improved, and it is also convenient to connect the first shear wall 1 as a whole with the building body 3. At the same time, the interconnection between each first sub-wall 1 ensures the overall vertical force transmission performance of the first shear wall 1. The second shear wall 2 is the same as the first shear wall 1, and will not be described in detail here. The following detailed description uses the first shear wall 1 as an example.

[0037] Reference Figure 2 This embodiment provides a modular steel building structure. The first sub-wall 11 includes a wall panel 111 and two wall columns 112. The wall panel 111 is positioned between the two vertical wall columns 112, which provide support and fixation for the wall panel 111. The upper end of the wall column 112 is vertically connected to the ceiling beam 311 of the steel structure module 31, and the lower end of the wall column 112 is vertically connected to the floor beam 312 of the steel structure module 31. The wall panel 111 is preferably a buckling-resistance steel plate shear wall, and the specific model is selected according to the prior art.

[0038] Reference Figure 2 and Figure 3This embodiment provides a modular steel building structure. The first shear wall 1 further includes a connector 12, a first connecting corner box 13, and a second connecting corner box 14. For one of the steel structure modules 31, the first connecting corner box 13 is positioned upwards on the ceiling beam 311 of the steel structure module 31, corresponding to the wall column 112. The second connecting corner box 14 is positioned downwards on the floor beam 312 of the steel structure module 31, corresponding to the wall column 112. The adjacent first connecting corner boxes 13 and second connecting corner boxes 14 are vertically connected. When two adjacent steel structure modules 31 are connected, the second connecting corner box 14 of the upper steel structure module 31 is adjacent to the first connecting corner box 13 of the lower steel structure module 31. The connector 12 passes through both adjacent first connecting corner boxes 13 and second connecting corner boxes 14 to connect them. In this way, the vertical connection between the first sub-walls 11 is achieved.

[0039] Reference Figure 3 and Figure 4 This embodiment provides a modular steel building structure. The connector 12 includes an upper insert 121, a lower insert 122, and a connecting plate 123. The upper insert 121 and the lower insert 122 are vertically arranged on both sides of the connecting plate 123, and the connection area between the upper insert 121 and the lower insert 122 and the connecting plate 123 is located in the middle of the connecting plate 123. When two adjacent steel structure modules 31 are connected, the upper insert 121 is inserted into the second connecting corner box 14 of the upper steel structure module 31, and the lower insert 122 is inserted into the first connecting corner box 13 of the lower steel structure module 31. The connecting plate 123 is located between the first connecting corner box 13 and the second connecting corner box 14.

[0040] The opening size and shape of the first connecting corner box 13 and the second connecting corner box 14 are adapted to be inserted into the corresponding lower plug-in 122 and upper plug-in 121.

[0041] Reference Figure 3 , Figure 4 and Figure 5This embodiment provides a modular steel building structure. The upper part of the second connecting corner box 14 is provided with a grouting hole and a grout outlet hole (not shown in the figure). The grouting hole is not higher than the grout outlet hole to ensure the grouting effect. The upper plug-in 121 and the lower plug-in 122 are both square steels that are open at both ends. When two adjacent steel structure modules 31 are connected, they can play a limiting role. The connecting plate 123 is provided with a through hole 1231, through which the upper plug-in 121 and the lower plug-in 122 are connected. During grouting, grout is injected through the grouting hole of the second connecting corner box 14. The grout is injected sequentially into the second connecting corner box 14, the upper plug-in 121, the through hole 1231 on the connecting plate 123, the lower plug-in 122 and the first connecting corner box 13. After the grout solidifies, the connection between the first connecting corner box 13 and the second connecting corner box 14 is completed.

[0042] Reference Figure 3 , Figure 4 and Figure 5 This embodiment provides a steel modular building structure. The connector 12 further includes at least two pull-out resistant portions 124. The two pull-out resistant portions 124 are vertically arranged one-to-one on the side walls of the upper plug-in 121 and the lower plug-in 122, and play a pull-out resistant role vertically between the first connecting corner box 13 and the second connecting corner (adjacent two first sub-walls 11). Multiple pull-out resistant portions 124 can be provided. The pull-out resistant portions 124 located on the side walls of the upper plug-in 121 and the lower plug-in 122 are centrally symmetrically distributed to achieve the best pull-out resistant effect.

[0043] Reference Figure 3 This embodiment provides a modular steel building structure in which the bending stiffness of the ceiling beam 311 section accounts for 80%-100% of the bending stiffness of the floor beam 312 section. This can increase the proportion of shear deformation of the shear wall in the structure, which is beneficial to improving the overall lateral resistance and energy dissipation capacity of the main building 3.

[0044] Reference Figure 3 This embodiment provides a modular steel building structure, in which the wall column 112 is an I-beam. The end faces of the two flanges of the I-beam are opposite to the end faces of the two opposite side walls of the first connecting corner bracket 13 box or the second connecting corner bracket box 14, that is, the two flanges of the I-beam are aligned with the side walls of two of the first connecting corner bracket 13 box or the second connecting corner bracket box 14, which is conducive to vertical force transmission between adjacent first sub-walls 11.

[0045] In addition, the wall column 112 can also be made of square steel. In this case, the end face of the wall column 112 is opposite to the end face of the side wall of the first connecting corner box 13 or the second connecting corner box 14 connected to it. That is, the side wall of the wall column 112 is aligned with the side wall of the first connecting corner box 13 or the second connecting corner box 14, which is conducive to vertical force transmission between the adjacent first sub-walls 11.
