Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of fabricated building, and relates to a sliding vibration isolation modular building. BACKGROUND

[0002] Modular building refers to a building form that a room unit is taken as a prefabricated component unit, and the prefabricated component unit is transported to a construction site for installation after being prefabricated in a factory. The prefabricated module can be a room unit that is complete in decoration and is provided with all pipe networks such as heating, sewerage and lighting. The modular building is the highest integrated form of industrialized fabricated building. The modular building has the advantages of short construction period, saving of manpower, construction safety, guaranteed quality and the like, and is in line with the concepts of building industrialization and low-carbon construction.

[0003] The seismic performance of the modular building structure depends on the mechanical performance of the module itself and the deformation coordination between the modules. Considering transportation and hoisting and the use requirements of the building, the component section of the module unit is relatively thin, and the module unit is provided with light partition walls, doors, windows and other non-structural components. Therefore, the deformation limit value requirement of the structure is relatively high. If sufficient seismic measures are taken at the module joint, the connection structure of the joint area will be very complex, which is not conducive to on-site assembly and is not economical.

[0004] The adoption of vibration isolation can reduce a large amount of seismic action transmitted to the upper structure, and reduce the stress requirement of the upper module unit and the connection between the module units. Designs similar to CN111827762A and CN206521843U have the similar design. However, there is no widely promoted modular building structure vibration isolation system at present. For example, the structure of the spring vibration isolator or damper arranged at the foundation is relatively complex; the damping of the sand cushion layer has a liquefaction risk; the cost of the rubber vibration isolation support is relatively high; and for the sliding vibration isolation, the setting of the limiter may cause the upper structure to suddenly bear a large force and increase the overturning risk.

[0005] It can be seen that suitable vibration isolation measures should be effective in any horizontal direction, and should not have adverse effects in other degrees of freedom. In addition, the vibration isolation structure should meet the deviation requirements generated during construction. Within the allowable range, the vibration isolation structure should remain effective. For the rapid construction method of modular building, the vibration isolation measures should have a simple structure, a low cost, be insensitive to construction errors, and can achieve the sliding vibration isolation design target under different fortification intensities. Then, there is no report on the vibration isolation device meeting the above requirements at present. The utility model is proposed based on this. UTILITY MODEL CONTENTS
