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
  • The present invention belongs to the field of civil engineering technologies, and more particularly, to flexibly suspended modular building structure.
  • BACKGROUND
  • A module building is a prefabricated assembly-type three-dimensional box unit, one unit generally has 1 to 3 rooms, the module unit is usually manufactured by steel structure, the module manufacturing and equipment installation account for 90% of the total construction quantity, and are both finished on the assembly line of the factory, which has high mechanization and industrialization degrees, and reduces the pollutant discharge. The manufacturer integrates the external wall, decoration, furniture, equipment, etc. in the box unit (module) and delivers them to the site for lifting and assembling, which not only has convenient construction in structure part, but also omits the decoration and other work in a later stage.
  • Compared with other prefabricated assembly structures, the module building has the advantages on the following aspect mainly: due to high integration, the subsequent decoration, equipment and pipeline installation and other procedures are omitted, which further shortens the construction time and saves the human resources on site; each module forms a structure system itself; no matter the transportation and lifting, or the positioning does not need additional supporting or bracing parts, and relatively convenient piling in place can be used; moreover, the decoration and equipment installation conducted by the factory assembly-line further improve the indoor quality, which better complies with the market requirements on commercial houses.
  • On the basis of the advantages on the aspects above, the module building is applied to but is not limited to the following occasions: a project with an urgent construction period, such as school dormitories where the new student needs to move in on schedule; a project that is short of manpower, such as the construction with scale in remote regions; a project under challenging weather conditions, such as winter construction; and a project having special requirements on the decoration quality, such as starred hotel, etc.
  • Moreover, limited by the space requirement, connecting convenience requirement and self-weight, the members in the module have limited size, which cannot reach a very high level of horizontal bearing capacity. Therefore, in the practical engineering application at current, multi-story and high-rise module buildings need to be externally added with an anti-lateral structure which can be a concrete core tube or other forms to help the module buildings to bear lateral loads. The module delivers the horizontal load to the core tube through effective connection, and the module itself only bears the vertical load and little horizontal load. Therefore, in the high-rise module building case, the structure form of module + concrete core tube is generally used, an anti-horizontal seismic force system only has one defense line (the core tube), which is a relatively unreasonable structure form. overlarge horizontal load delivering from the module to the core tube usually causes great material consumption. On the other hand, in the high-rise module building case, the self-weight of the module is directly delivered downwardly, the module at the bottom bears overlarge vertical load, which increases the size of the internal members of the module, and further increases the self-weight of the structure, so as to affect the use function.

  • In order to provide exemplary embodiments, three installation methods of hanging section modules are described as follows:
    • First method: aligned piling in place:
      1. 1. For the installation in place of a bottom platform: the function of the platform is to bear temporary vertical loads of modules on the platform. If the bottom of the structure is provided with a piling module, then the bottom module is directly installed.
      2. 2. After the module or the platform on a lower story is installed, a temporary block is installed, and the function of the temporary block is to reserve a vertical space, so that the module is not contacted in a vertical direction in a system formed finally; and after the temporary block is installed and leveled, the module of this story is lifted in place.
      3. 3. After the module of each story is installed in place subsequently, the hanging rod member and the limiting buffer device are installed, then the damper between the core tube structure and the module is installed, and other pipelines are connected.
      4. 4. The temporary block is withdrawn from the top to bottom, and the bottom platform is removed finally.
    • Second method: dislocation piling in place, as shown in Fig. 7:
      1. 1. For the installation in place of a lifting platform 25: the platform has a lifting device, and can be steadily and entirely lifted, with a small stroke required. The distance between the lifting platform 25 and the hanging transfer story is slightly larger than the height of the overall hanging section by subtracting the sum of the vertical space between the modules. That is to say, according to the solution that the modules are tightly piled up in the vertical direction without the temporary block, a distance with the transfer story is reserved as the operation space.
      2. 2. After the module or the platform on the lower story is installed, the module of this story is lifted in place, and the hanging rod member is connected. The modules at two storys are tightly piled up in the vertical direction to form certain dislocation in the horizontal direction, and the distance of the dislocation is determined according to the standard that the hanging rod member can be accurately connected.
      3. 3. After the module at each story is installed in place subsequently, the hanging rod member at the top story is installed, and then the lifting device of the bottom platform is used, so that the platform can decline steadily, until the module at the hanging end is naturally suspended. Then the platform is withdrawn.
      4. 4. The limiting buffer device is installed, the damper between the core tube structure and the module is installed, and other pipelines are connected.
    • Third method: hanging in place, as shown in Fig. 8:
      1. 1. The corresponding position of the core tube structure shall be provided with a pre-buried member 26, so that the module is temporarily suspended outside the core tube. The position of the pre-buried member at the top story is determined according to the standard that the pre-buried member can be accurately connected to the hanging rod member with the transfer story, and the position of the pre-buried member is calculated from top to bottom in sequence according to the standard.
      2. 2. The module is lifted by using the transfer story, the module at the top story is firstly lifted and installed, and is connected to the pre-buried member, and then the hanging rod is installed to form temporary fixation.
      3. 3. Step "2" is repeated in sequence from top to bottom.
      4. 4. The temporary fixation between the hanging modules and the pre-buried members at the top two stories is released to form a mechanism, so that the hanging modules and the pre-buried members are in place automatically under the effect of gravity, i.e., swinging to the corresponding positions horizontally. The limiting buffer device and the damper of the module at the top story are installed after being in place.
      5. 5. The temporary fixation of the modules of one story is released gradually from top to bottom, and after the modules are in place, the limiting buffer device and the damper of the module of the story above this story are installed.
      6. 6. The limiting buffer device and the damper of the module at the bottom story are installed, and other pipelines are connected.
  • The contents above are only preferred embodiments of the invention. It shall be pointed out that those skilled in the art can make a plurality of improvements and polishing without departing from the principle of the invention, which shall also fall within the protection scope of the invention.
