As shown in Figure 1, Figure 3 and Figure 5, in another embodiment of the present application, the multi-storey modular house includes a plurality of first boxes 2 arranged side by side, and a plurality of second boxes 3 arranged side by side , the multi-storey modular house also includes a first backing plate 5 and a second backing plate 6, the two corners of the top of the first box body 2 located at the outermost side of the multi-storey modular house are respectively provided with a first backing plate 5, and the first backing plate The plate 5 is specifically arranged between the first connection module 11 at the top of the first box body 2 and the connection block 123 at the bottom of the second box body 3, and the first backing plate 5 is provided with a third through hole for the connecting piece 13 to pass through. 7; Two second backing plates 6 are provided at the four corners where two adjacent first boxes 2 abut against each other, and the second backing plates 6 are placed across the tops of the two adjacent first box bodies 2, and the second backing plates 6 are specifically set Between the first connecting module 11 on the top of the first box body 2 and the connecting block 123 on the bottom of the second box body 3 , and the second backing plate 6 is provided with two third through holes 7 through which the connecting piece 13 passes.

In actual situations, if the first connection module 11 and the second connection module 12 of the upper and lower boxes directly contact the support, it is necessary to precisely control the surface accuracy of the first connection module 11 and the second connection module 12 to ensure that the upper and lower boxes The body is tilted and toppled, which will greatly increase the manufacturing cost. In the present embodiment, a first backing plate 5 and a second backing plate 6 are arranged on the top of each first box body 2, so as to isolate and support each second box body 3. During production, as long as the first backing plate is raised The surface accuracy of the first backing plate 5 and the second backing plate 6 is sufficient, thereby reducing manufacturing costs.

The above are only optional embodiments of the application, and are not intended to limit the application. For those skilled in the art, various modifications and changes may occur in this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of the claims of the present application.
