Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, and in particular to a modular swing wall building structure. BACKGROUND

[0002] In recent years, with the rapid development of the building industry and the increasingly prominent problem of population aging in China, the traditional building method has exposed a series of problems such as obvious labor-intensive characteristics, long construction period, difficult to guarantee construction quality, and serious noise and pollution on the construction site. Therefore, the building industry gradually turns to the development direction of modular building.

[0003] The current modular concrete structure building mainly includes three forms of stacked frame structure, frame-module structure and shear wall-module structure.

[0004] The stacked frame structure is composed of module units, and the module units include two types of prefabricated lateral force resisting module units and prefabricated gravity module units. The lateral force resisting module units resist earthquake action; the gravity module units only bear their own gravity and do not participate in seismic resistance. Its advantages are high degree of modularization, short construction period and less environmental pollution. However, it has the problems of insufficient seismic performance, serious damage after earthquake and difficulty in repair, and is only suitable for areas with low seismic requirements.

[0005] The frame-module structure is composed of cast-in-place frame structure and prefabricated module structure. The frame structure resists earthquake action; the module structure is composed of prefabricated gravity module units and only bears gravity. The connection between the frame structure and the module structure and the connection between the module units of the module structure are all cast-in-place construction. This structure has good seismic performance, but has the disadvantages of long construction period (usually 1-2 years), high on-site pollution, serious damage after earthquake and difficulty in repair.

[0006] The shear wall-module structure includes cast-in-place shear wall structure and prefabricated module structure, wherein: the shear wall structure includes shear walls and coupling beams and other lateral force resisting members, and resists earthquake action; the module structure is composed of prefabricated gravity module units and only bears gravity. The connection between the shear wall structure and the module structure and the connection between the module units of the module structure are cast-in-place construction. Although this structure has good seismic performance, it also has the problems of long construction period, high pollution, serious damage after earthquake and difficulty in repair.

[0007] In summary, the above three structure forms have the disadvantages of extremely high precision requirements for on-site assembly of module units, easy assembly errors that cannot be connected, serious damage after earthquake and difficulty in repair, and module structure units that cannot be disassembled and replaced. SUMMARY

[0008] In view of the lack and deficiency of the existing modular concrete structure building, the application provides a novel building system of a module structure- rocking wall structure based on a sliding friction connecting node. Under the system, the modular rocking wall building structure can effectively improve construction efficiency and building quality, significantly reduce the precision requirement of the house module, and ensure slight damage of the building under a large earthquake, and the module can be replaced.

[0009] The technical scheme of the application is:

[0010] A novel building system of a module structure- rocking wall structure based on a sliding friction connecting node, comprising a rocking wall structure 2, a module structure 1 and a node system.

[0011] The rocking wall structure 2 is a lateral force resisting structure for resisting earthquake action.

[0012] The module structure 1 is a building functional structure, comprising a plurality of module units 11, and the module unit is a gravity module unit.

[0013] The node system comprises a sliding friction connecting node 31 and a horizontal force transmission member 32; the sliding friction connecting node 31 is used for connecting the module units 11 in the module structure 1 and connecting the module structure 1 and the rocking wall structure 2; and the horizontal force transmission member 32 is arranged between the module structure 1 and the rocking wall structure 2 and is used for transmitting horizontal force.

[0014] The application has the following beneficial effects:

[0015] (1) Since the sliding friction connecting node is adopted, the module units are allowed to slide, and the precision requirement of the house module is significantly reduced.

[0016] (2) Since the sliding friction connecting node is adopted, the module structure can be substantially undamaged under an earthquake, and the damper in the rocking wall structure is used for energy dissipation, so that the safety of the building under a large earthquake is ensured. In addition, since the rocking wall structure is adopted, the damage is concentrated in the damper, so that the building is easy to repair after the earthquake, and only the damper needs to be replaced after the earthquake.

[0017] (3) The module structure of the application is detachable, and if a module unit is damaged due to fire or other unexpected situations, the module unit can be individually detached and replaced, so that the risk of reducing the safety of the module structure due to fire or other unexpected situations is prevented.
