A flexible suspended modular building structure

Abstract

The invention discloses a flexibly suspended modular building structure, which comprises a vertical core tube structure. A conversion story is arranged at the upper end of the core tube structure, multiple modules with certain spaces reserved therebetween are hung below the conversion layer, the modules adjacent in the vertical direction are connected through a set of hanging rod members, the upper end of each hanging rod member is pin-connected to a ceiling beam located in the upper module, the lower end of each hanging rod member is pin-connected to a ceiling beam located in the lower module, the hanging rod member arranged on the uppermost module is pin-connected to the transfer story, and dampers are connected between floors of all the modules and the core tube structure. By means of suspension shock absorption technology, the horizontal loads inputted by the modules to the core tube structure are remarkably reduced, and the material consumption of the core tube structure is saved. The module building allows inter-story drift of secondary structure, prevents non-structural elements from damage, and extends the limit value of inter-story drift between modules, thus improving the energy dissipation and shock absorption efficiency. By introducing a limiting buffer device, relative displacement between the modules is controlled, and collision is avoided.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, in particular to a flexible suspension modular building structure. Background technique [0002] The modular building is a prefabricated three-dimensional box unit. There are generally 1-3 rooms in a unit. The modular unit is generally made of steel structure. The module production and equipment installation account for 90% of the total construction work, and they are all on the factory assembly line. Complete, high degree of mechanization and industrialization, and reduce pollution emissions. The manufacturer integrates the exterior walls, decoration, furniture, equipment, etc. into this box unit (module), and transports it to the site for hoisting and splicing, which not only facilitates the construction of the structural part, but also eliminates the need for later decoration and other work. [0003] Compared with other prefabricated assembly structures, the advantages of modular bu...

Problems solved by technology

Therefore, in the case of high-rise modular buildings, the structural form of modules + concrete core tubes is generally adopted, and the anti-horizontal earthquake force system has only one defense line of the core tube, which is a relatively unreasonable structural form

The module transmits excessive horizontal load to the core tube, often resulting in a large amount of material

On the other hand, in the case of high-rise modular buildings, the self-weight of the modules is directly transmitted downwards, and the modules at the bottom bear excessive vertical loads, which increases the size of the internal components of the modules, which in turn increases the self-weight of the structure, affecting the use function
