Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is used as a reference.

[0040] Embodiment 1:

[0041] Reference Figure 1-Figure 9 The embodiment of the utility model provides a concrete modular building suitable for the renovation of old communities, which is suitable for the original demolition and reconstruction of old communities. The modular building includes a plurality of concrete modules 1 divided into the same-floor space according to different indoor space functions, and a plurality of prefabricated components 2 divided into public areas according to functions; wherein the prefabricated components 2 include a shear wall 21, a first casting cavity 201 is formed in the shear wall 21, and a second casting cavity 202 is formed between adjacent concrete modules 1 corresponding to the shear position of the floor space, and / or between adjacent prefabricated components 2 and concrete modules 1; concrete can be cast in the first casting cavity 201 and the second casting cavity 202 to form a shear zone of the floor.

[0042] In this embodiment, by pouring concrete on-site in the preset first pouring cavity 201 and the second pouring cavity 202 to form the shear zone of the floor, the shear zone can be integrated with the corresponding concrete module 1 and / or prefabricated component 2, thereby improving the consistency of the shear zone with the prefabricated component 2 and the concrete module 1, thereby improving the overall strength of the modular building and improving the seismic resistance.

[0043] Specifically, steel cages are arranged in the first pouring cavity 201 and the second pouring cavity 202 and then concrete is poured.

[0044] By setting a plurality of concrete modules 1 of different types and freely combining the concrete modules 1 according to the building plan, the rapid construction of old residential projects can be achieved and the pressure of old residential renovation can be reduced.

[0045] The concrete module 1 and the prefabricated component 2 can be prefabricated in an industrial factory after the scheme design to achieve standardized and rapid production; the concrete module 1 can be divided according to the different functions of the building's interior space during the scheme design stage, and each module can meet the functional requirements of the building space, greatly improving the construction convenience and speed, and reducing the time cost of construction.

[0046] Specifically, the concrete module 1 includes a room module 11, a kitchen module 12 and a bathroom module 13; the prefabricated component 2 also includes a walkway slab 22, a staircase 23, an exterior wall 24, an elevator shaft 25 and a balcony 26, wherein the concrete module 1 presets interior decoration and pipelines, and the concrete module 1 integrates one, several or all of the structure, decoration, doors and windows, electromechanical pipelines, equipment accessories and furniture. The height of the concrete module 1 is consistent with the floor height of the floor space to improve the size consistency of the concrete module 1 and omit the later repair and adjustment steps.

[0047] After the modules are freely assembled, door and window openings can be set on the partition wall according to the traffic demand on the same floor, and stairs 23 can be set according to the traffic demand on the upper and lower floors.

[0048] The concrete module 1 is integrated with structure, decoration, doors and windows, electromechanical pipelines, equipment accessories and even furniture during production, and then transported to the construction site. It can be assembled through reliable connection methods and quickly built into a permanent building that meets earthquake resistance and fire protection requirements, thereby improving construction efficiency.

The top side wall of the bathroom module 13 with bathroom space includes a top drop plate 131, and the bottom side wall of the bathroom module 13 includes a bottom drop plate 132. The positions and shapes of the bottom drop plates 132 and the top drop plates 131 of the adjacent floor spaces are consistent. By lowering the top side walls and the bottom side walls of the bathroom, the indoor height of the bathroom can better meet the drainage requirements. The top drop plates 131 and the bottom drop plates 132 that match each other can also play a certain positioning role, thereby improving the assembly convenience of the concrete module 1 serving as a bathroom.

[0050] The modular building also includes a steel frame roof 5, which is connected to the top surface of the top modular building to form the roof part of the modular building. The steel frame roof 5 is also connected to the top building in the form of integral casting to ensure its connection strength.

[0051] The modular building further comprises connection areas 4 provided on the concrete modules 1 and the precast components 2, connection areas 4 between adjacent precast components 2, and / or connection areas 4 between adjacent precast components 2 and the concrete modules 1, which are connected to each other by poured concrete.

[0052] In this embodiment, the connection relationship between adjacent prefabricated components 2 and / or between adjacent prefabricated components 2 and concrete modules 1 is established through the connection area 4, thereby improving the integrity of adjacent components. Specifically, the connection area 4 is a gap structure, and after a steel cage is placed in the gap, concrete can be poured.

Preferably, the composite floor 3 is arranged one-to-one with the concrete module 1. During the construction process, the shear zone and the rib layer 6 are cast as an integrated structure, and the composite floor 3 is laid on the rib layer 6, so that all the shear zones can be integrated under the connection of the rib layer 6, thereby further improving the stability of the modular building and improving its seismic resistance.

[0057] The composite floor 3 where the reinforcement layer 6 is connected to the shear zone needs to give way to connect the shear zones of adjacent floors through the reinforcement layer 6, thereby further improving the seismic performance of the modular building.

[0058] The modular building pouring process is as follows:
