technical field

The utility model relates to a modular building structure, in particular to a hanging modular building structure.

Background technique

Modular building is a new building structure system, which uses each room as a modular unit, each modular unit is prefabricated in the factory, and the internal space of the module can be arranged and decorated in the factory. Transported to the site, the central structure (such as the core tube) of the modular building is usually completed on site. The core tube can be a reinforced concrete structure poured on site, or a steel structure or a steel-concrete composite structure. And the unit modules and the core tube are assembled into a whole building through reliable connection. Building modular units are usually self-contained inside and require little on-site technicians, thus greatly reducing on-site working time. Compared with the construction methods of traditional buildings, modular buildings have the advantages of shortening the construction period, saving manpower and material resources, being green and environmentally friendly, and having excellent quality.

China's authorized utility model patent (ZL201420038867.1) discloses a building module and a medium-high-rise modular building with the building module, including: a frame; a roof board and a floor board respectively arranged on the top surface, the bottom surface and the side of the frame And the wall, the wall includes the outer wall, the inner wall and the insulation layer between the outer wall and the inner wall, and the door and window are arranged on the wall; the connecting part is used for connecting the building module The core tubes surrounding the middle and high-rise modular buildings are stacked to connect adjacent building modules, and to connect the building modules and the core tubes. The medium-high-rise modular building is mainly composed of a core tube and multiple building module units, and multiple building modules surround the core tube and are stacked into a multi-storey building structure. The core tube runs through the height of the entire building structure, and multiple building modules are combined with the core tube to form a floor structure of the building structure. The floor structure composed of building modules is superimposed layer by layer in the height direction of the core tube to form a high-rise building.

But above-mentioned modular building also exists following defective in construction process:

⑴The modular building adopts the method of stacking and assembling. The building modules need to be connected, and each building module is also connected to the core tube. The skeleton of the building module participates in the overall force of the building structure, that is, the skeleton of the building module is the skeleton of the building structure. component. The modular building is more suitable for low and multi-storey buildings (the number of building floors is less than 7 floors). When it is used in high-rise and super high-rise buildings (the number of building floors is greater than 10 floors), according to the stress characteristics of the building modules, it is assembled according to the superposition In this way, the force is transmitted layer by layer, and the skeleton section of the building module will show a situation where the bottom is large and the top is small, and the type of section needs to be increased, which makes the standardization of manufacturing and the convenience of installation greatly reduced.

(2) The building modules are connected both horizontally and vertically, resulting in many on-site installation nodes, cumbersome construction, prolonging the construction period, and large safety hazards, difficult to control precision, which is not conducive to the popularization and application of modular buildings.
