[0032] Here, the factory is prefabricated using functional modules:

[0033] The functional modules are prefabricated in the factory in a standardized and stereotyped rectangular shape. An inverted L-shaped high-strength steel hook is set on one side for attachment to the core tube, and a groove is set on the other side.

[0034] like Figure 2 As shown, the support device construction:

[0035] When the number of functional modules designed for hoisting is large, in order to enhance the overall safety of the building and improve its rigidity and stability, a support device can be symmetrically set. The support device consists of an ultra-deeply buried rectangular steel sleeve column, multiple bottom supports, and triangular steel trusses fixed on the ground on both sides of the steel column. During the hoisting of the functional module, the grooves reserved on the outside of each layer are clamped and fixed with the protrusions of the rectangular steel sleeve column, and the bottom supports are set under the functional modules of the corresponding elevation and tightened with the rectangular steel sleeve column. The entire hanging modular building construction is completed in sequence.

[0036] In one embodiment of the core tube hanging modular building of the present invention, the shapes of the hanging point and the hook are both L-shaped.

[0037] In one embodiment of the core tube hanging modular building of the present invention, the core tube is prefabricated in sections, each section has an axial length of 3-5 meters, and is divided into a bottom section, an intermediate section and a top section; the bottom section is provided with an anchor plate and a grouting connection sleeve hole is reserved for grouting and fixing with the core tube pedestal; the top section is reserved with a steel boom mounting base, and the steel boom mounting base is connected to the steel boom device 14; the side wall of the intermediate section has reserved steel bars at the bottom and reserved sleeve holes at the top, and the upper and lower adjacent sections of the core tube are connected by grouting with inserted bars.

[0038] Here, the core segments (including mounting points and auxiliary functions) are prefabricated in the factory:

[0039] The cross-section of the core tube can be rectangular or circular, and sufficient rigidity is ensured. Auxiliary building function modules such as elevator shafts and fire stairs are set on the inside of the core tube, and L-shaped mounting points are reserved on the outside of the core tube; the core tube is prefabricated in segments, each with an axial length of 3-5 meters, divided into bottom segments, middle segments and top segments. The bottom segment of the core tube is provided with anchor plates and reserved grouting connection holes for grouting and fixing with the core tube pedestal; the top segment of the core tube is reserved with a steel boom mounting base for connection with the steel boom device; the side walls of the middle segments of the remaining core tubes are reserved with steel bars at the bottom and holes at the top, and the upper and lower adjacent segments of the core tube are connected by rebar grouting.

[0040] Use function module construction:

[0041] like Figure 4 As shown, a steel boom device is installed on the top segment of the core tube, and the functional module is transported to the site and symmetrically hoisted to a predetermined height. The hook of the functional module and the reserved mounting point of the core tube are connected and fixed by high-strength bolts 10.

[0042] like Figure 1 As shown, in one embodiment of the core tube hanging modular building of the present invention, it also includes:

[0043] A core tube pedestal 11, wherein the core tube pedestal 11 is connected to the lower portion of the bottom segment of the core tube;

[0044] Bored cast-in-place piles 12 : The lower part of the core tube pedestal 11 is connected with bored cast-in-place piles 12 .

[0045] Here, the construction site foundation construction:

[0046] On-site measurement and positioning, bored cast-in-place piles are driven along the core tube section as the foundation of the entire core tube force structure. The bored cast-in-place piles are overcast by 1-2 meters according to the design elevation. The top steel bars of the bored cast-in-place piles are welded to the steel bars of the core tube pedestal and poured into the concrete of the core tube pedestal. The bored cast-in-place piles and the core tube pedestal form a force-bearing whole, forming the foundation of the core tube hanging modular building, which plays a role in reducing settlement, stabilizing the structure, and resisting lateral pulling caused by asymmetric module mounting and unbalanced force. The vertical steel bars reserved at the top of the pedestal are connected to the reserved sleeves at the bottom of the core tube segment for tube grouting.

[0047] like Figure 3 As shown, in one embodiment of the core tube hanging modular building of the present invention, a ground anchor plate 13 is further provided on the side wall of the bottom segment of the core tube, and the ground anchor plate is fixed to the hardened ground by ground anchor bolts.

The vertical steel bars reserved on the top of the core tube pedestal are aligned and inserted into the reserved connection sleeves of the bottom segments of the core tube. The bottom segments of the core tube and the core tube pedestal are fixed by grouting. The anchor bolts of the bottom segments are then fixed on the hardened site with anchor bolts. The remaining segments of the core tube are then hoisted and grouted in sequence. After the core tube is completed, its verticality is tested to meet the specific construction requirements, and the auxiliary functional modules of the building in the core tube are vertically integrated.

[0050] like Figure 5 As shown, repair and replace:

[0051] When a functional module needs to be replaced during long-term use, the module is first suspended with the top segment steel boom device, and then the hook of the functional module and the mounting point bolts of the core tube are removed, and then the functional module is lifted out of the entire building structure in the horizontal plane, and finally the new functional module is lifted into the designated position and fixedly connected to the core tube with bolts. If support devices are set on both sides, the functional modules can be removed and lifted from top to bottom in sequence, and the damaged functional modules can be replaced and then lifted and installed in sequence according to normal construction methods.
