The bottom plate of the ceiling is combined and connected with the free end of the stairs, so that residents can climb to the top floor of the building through the stairs.

The combined building body has a through gap formed on its four sides, and the bathroom in the second module unit of the first combined module is adjacent to the through gap. With such a structure, when installing the pipeline in the building body, install the pipeline in the through gap. Then directly communicate with the pipeline opening of the preset value of the toilet of each floor resident and get final product. Since the pipes located in the external void of the building are vertical from bottom to top, the length of the pipes is reduced, the installation cost of the pipes is reduced, and future maintenance is also convenient. And because the external pipes are located in the gaps, the building as a whole looks more beautiful and tidy.

For the convenience of life, an elevator module can be set at one of the through gaps formed by the building body, and the elevator module communicates with the second combination module on each floor, so that residents can enter the first combination module through the second combination module.

This society all pursues individuality at present, therefore, also have a lot of individualized designs that satisfy the resident for the building body of the combination of the utility model design. When the same resident lives in the first combination module that is adjacent up and down, it is very inconvenient to enter the upper and lower floors through the stairs of the second combination module. Therefore, in the utility model, when prefabricating on the bottom plate of the first combination module on the upper floor, A detachable stairway cover can be provided. When the resident needs to connect the upper and lower floors indoors, an indoor staircase module can be added in the first combination module of the lower floor. At the stairway on the base plate of the combination module, at this moment, the stairway cover plate on the upper floor can be removed. When the resident does not need indoor stairs, the stairway cover plate on the base plate of the upper floor can be fixed with the base plate by a permanent fixture.

When the first combined modules adjacent to the same level need to be connected, a balcony module that can extend across the width of the gap can be added, and the balcony module extends to one end of the adjacent first combined module and the first combined module in a detachable manner It is fixedly connected, and a passage leading to the balcony is opened on the side wall of the first combined module to be connected. In order to shelter from wind and rain, a rain-shielding transparent roof can be installed above the balcony where the extension is located in the gap.

The building body combined by combining modules of the utility model can be built into a row building body. According to the above combination method, four first combination modules are combined at the four corners of the second combination module on each floor vertically stacked to form a combined building body unit, and each building body unit is pressed together to form a row building body . Such row building bodies can improve the building strength of each combined building body unit due to their mutual abutment. Of course, in order to further improve the strength of the row buildings, the building units that are against each other can be fastened together by fasteners to form a whole.

The building combination module designed by the utility model has high land use efficiency, good lighting effect of the combined building, and the building space is suitable for living. Since the size of each module meets the needs of transportation, it can be pre-assembled and then transported to the construction site, where it can be assembled and assembled quickly to form a new building. The building difference of the utility model and the current container-type combined house is that its land utilization rate and space utilization rate are high, its space division can be divided into living function areas according to user needs, and its appearance is beautiful, which can be compared with the permanent architectural style. Suitable for temporary or permanent residence. When a large number of demolished residents or disaster-stricken residents have nowhere to live, the composite building of the utility model can provide a large number of houses in a short time to meet the needs. It can be permanently inhabited when needed, and can be disassembled and moved for reuse when not needed.
