Description

Technical Field

[0001] The present invention relates to the field of construction engineering, and in particular to a core tube modular staggered stacking structural system. Background Art

[0002] The current modular structure is limited to a modular structural composition form, and has prominent shortcomings such as poor lateral resistance, large steel consumption, and poor economy. This makes the modular structure only suitable for low-rise and multi-story buildings, seriously restricting the development and application of the modular structure, and completely unable to give full play to the advantage of the high assembly rate of the modular structure.

[0003] As a structural system with excellent lateral resistance, the core tube structure is currently widely used in high-rise buildings. However, the core tube structure, primarily a frame-type structure, still has the following shortcomings during actual construction: The concrete structure within the frame-type core tube structure results in low core tube construction efficiency, resulting in a prolonged project cycle. Furthermore, the heavy weight of the prefabricated modules makes transportation and hoisting difficult, and module connection is inconvenient, failing to meet the requirements of high-rise buildings. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a core tube modular staggered stacking structure system.

[0005] A core tube modular staggered stacking structural system includes a core tube, a frame module, a horizontal connection assembly and a module connection assembly. A plurality of the frame modules are staggered and stacked through the module connection assembly to form a multi-layer and multi-column rectangular main structure; the rectangular main structure is arranged around the core tube and is connected to the core tube through the horizontal connection assembly.

[0006] Furthermore, the horizontal connection assembly includes at least two ear plates and a pin shaft, the core tube and the frame module are respectively connected with at least one ear plate, and the pin shaft locks the core tube and the frame module together after passing through all the ear plates.

[0007] Furthermore, at least one of the core tube, the frame module, and the module connection assembly is provided with the ear plate.

[0008] Furthermore, each group of the module connection components includes a C-shaped plug-in block and a C-shaped plug-in tube; when two groups of the module connection components are plugged in, a grouting space is formed in the C-shaped plug-in block of one module connection component and the C-shaped plug-in tube of the other module connection component; the ear plate of the horizontal connection component is connected to the C-shaped plug-in tube.

[0009] Furthermore, at least one of the core tube and the frame module is pre-embedded with steel bars, one end of the steel bars is connected to the core tube, and the other end thereof is connected to the frame module.

[0010] Furthermore, the core tube includes a plurality of rectangular parallelepiped frame bodies, and the eight end points of the frame bodies are provided with the module connection components. The plurality of frame bodies are staggered and stacked and connected through the module connection components to form the core tube.

[0011] Furthermore, the frame body includes a first column, a first beam and a diagonal brace, and every eight first beams and every four first columns are connected to the module connection assembly to form a single frame body; the two ends of the diagonal brace are respectively connected to two oppositely arranged first beams and are inclined relative to the vertical direction.

[0012] Furthermore, the core tube is formed as a whole by horizontally connecting multiple concrete core tubes. The concrete core tube includes shear walls and connecting beams. The shear walls are multiple pieces arranged vertically. The connecting beams are installed between adjacent shear walls. The shear walls and the connecting beams surround a hollow concrete core tube.

[0013] Furthermore, the frame module includes a second column, a second beam and a connecting beam, and every eight second beams and every four second columns are connected through the module connecting assembly to form a rectangular frame; one end of the four connecting beams is connected to the module connecting assembly, and the connecting beams extend horizontally outward from the second beam; the other end of each connecting beam is connected to the ear plate of the horizontal connecting assembly.

[0014] Furthermore, the frame module is a steel structure or a concrete structure.

[0015] The beneficial effects of the present invention are:

[0016] The structural system of the present invention can first construct the core tube, so that the core tube is arranged vertically, and multiple frame modules are arranged around the outer edge of the core tube. Any two adjacent frame modules are connected by module connection components, thereby staggering and stacking multiple frame modules to form a multi-layer, multi-column rectangular main structure. The frame modules are then connected to the core tube through horizontal connection components, and finally, concrete is poured to complete the construction of the entire structural system. In the present invention, the core tube and the frame modules are connected in a detachable relationship. While ensuring structural strength, it also simplifies the construction structure of the outer frame, reduces construction difficulty, and effectively improves the construction efficiency of the structural system.

[0032] Example 1

[0033] See also Figure 1 and Figure 2 As shown, the first embodiment of the present application relates to a modular staggered stacking core tube structure system. The modular staggered stacking core tube structure system includes a core tube 10, frame modules 20, horizontal connection assemblies 30, and module connection assemblies 40. Multiple frame modules 20 are staggered and connected via the module connection assemblies 40 to form a multi-layer, multi-column rectangular main structure. The rectangular main structure is arranged around the core tube 10 and connected to the core tube 10 via the horizontal connection assemblies 30.

[0034] like Figure 3 As shown, the core tube 10 includes a plurality of rectangular parallelepiped steel structure frames 13, each of which has a module connection assembly 40 at its eight end points. The plurality of frames 13 are staggered and stacked through the module connection assembly 40 to form the core tube 10. Figure 5 As shown, the frame body 13 includes a first column 14, a first beam 15, a diagonal brace 16, a first top plate 17 and a first bottom plate 18. Every eight first beams 15 and every four first columns 14 are connected by a first connecting assembly 20 to form a single frame body 13. The two ends of the diagonal brace 16 are respectively connected to the two oppositely arranged first beams 15, and are inclined relative to the vertical direction. One or more diagonal braces 16 can be provided between the upper and lower first beams 15, and two or more diagonal braces 16 can be inclined in the same direction, in opposite directions, or in a zigzag-shaped inclined distribution. The first top plate 17 is connected to the four first beams 15 at the upper end, and the first bottom plate 18 is connected to the four first beams 15 at the lower end.

[0035] By adding diagonal braces 16 between the upper and lower first beams 15, the frame 13 possesses a stiffness approaching that of a shear wall, yet its deadweight is much less than that of a shear wall and only slightly greater than that of a conventional frame structure. This significantly improves the stiffness of the core tube structure while reducing its deadweight, thereby minimizing seismic forces.

[0036] In order to strengthen the core tube's lateral resistance, Figure 4 and Figure 6 As shown, the core tube 10 is also pre-embedded with steel bars 40. One end of the steel bars 40 is horizontally overlapped on opposite sides of the frame body 13, and the other end extends to connect horizontally adjacent frame modules 20. Multiple steel bars 40 are evenly distributed along the first crossbeam 15 and are pre-embedded in the first top plate 17 and the first bottom plate 18.

[0037] like Figure 7 As shown, the frame module 20 is also a rectangular parallelepiped steel structure. Module connection assemblies 40 are provided at the eight endpoints of the frame module 20, connecting two adjacent frame modules 20 via the module connection assemblies 40. The frame module 20 includes second columns 21, second crossbeams 22, connecting beams 23, a second top plate 24, a second bottom plate 25, and a connecting plate 26. Every eight second crossbeams 22 and every four second columns 21 are connected to the module connection assemblies 40 to form a single frame. The second top plate 24 is connected to the four second crossbeams 22 at the upper end, and the second bottom plate 25 is connected to the four second crossbeams 22 at the lower end.

[0038] One end of the four connecting beams 23 is connected to the module connecting assembly 40, and the four connecting beams 23 extend horizontally outward from the four second cross beams 22. A lug 33 is provided at the other end of each connecting beam 23.

[0039] When the frame module 20 is connected to the core tube 10, the steel bars 50 of the core tube 10 are overlapped on the connecting plate 26 of the frame module 20, and the other end of the steel bars 50 is fixedly connected to the connecting plate 26 by post-cast concrete. Of course, the connecting plate 26 can also be pre-embedded with steel bars 50.

[0040] like Figure 6 As shown, the horizontal connection assembly 30 includes at least two lugs 33, at least one friction plate 32, and a pin 31. The core barrel 10 and the frame module 20 are each connected to at least one lug 33. The friction plates 32 and lugs 33 are stacked alternately, and the pin 31 passes through all the lugs 33 and friction plates 32 to lock the core barrel 10 and the frame module 20 together.

[0041] The modular connection assembly 40 includes a C-shaped plug-in block 41 and a C-shaped plug-in tube 42. The C-shaped plug-in block 41 can be inserted into the C-shaped plug-in tube 42 to form a grouting space. The bottoms of the C-shaped plug-in block 41 and the C-shaped plug-in tube 42 are connected to the first column 14 or the second column 21. One side wall of the C-shaped plug-in tube 42 is connected to the first crossbeam 15 or the second crossbeam 22, and the other side wall of the C-shaped plug-in tube 42 is connected to the ear plate 33 of the horizontal connection assembly 30. When two adjacent modular connection assemblies 40 are plugged in, a buffer gap is formed between the C-shaped plug-in tubes 42 of the two modular connection assemblies 40.

[0042] The outer wall of the C-shaped plug-in block 41 has a plurality of first bolts 43 extending horizontally outward, and the plurality of first bolts 43 are arranged in a plurality of vertical columns. The inner wall of the C-shaped plug-in tube 42 has a plurality of second bolts 44 extending horizontally inward, and the plurality of second bolts 44 are arranged in a plurality of vertical columns. After the C-shaped plug-in block 41 and the C-shaped plug-in tube 42 are plugged in, the vertical columns composed of the first bolts 43 and the vertical columns composed of the second bolts 44 are staggered with each other in the horizontal direction. The first bolts 43 and the second bolts 44 have the same structure. After the C-shaped plug-in block 41 and the C-shaped plug-in tube 42 are plugged in, a grouting space is formed, and slurry is injected into the grouting space. After the slurry solidifies, the two module connection components 40 are tightly connected. Since the grouting space is provided with the first bolts 43 and the second bolts 44, the reliability of the connection is improved.

[0043] Example 2

[0044] Please refer to Figure 8 As shown, the second embodiment of the present application provides a modular staggered stacking structure system of core tubes. The difference between this example and the first embodiment is that the core tube is no longer a modular structure, but a concrete structure.

[0045] A modular staggered core tube structure system includes a core tube 10, frame modules 20, horizontal connection assemblies 30, and module connection assemblies 40. The frame modules 20 are connected to the core tube 10 via the horizontal connection assemblies 30, and adjacent frame modules 20 are connected via the module connection assemblies 40. Multiple frame modules 20 are staggered and stacked to form a multi-layer rectangular main structure.

[0046] Combine Figure 9 As shown, the horizontal connection assembly 30 includes a pin 31, a friction plate 32, and ear plates 33 respectively provided on the core barrel 10 and the frame module 20. The friction plate 32 is clamped between two horizontally adjacent ear plates 33 and connected by the pin 31. A single frame module 20 is connected to the core barrel 10 via four sets of horizontal connection assemblies 30, and each set of horizontal connection assemblies 30 has at least one ear plate 33 on the core barrel 10 or the frame module 20. Preferably, one of the core barrel 10 or the frame module 20 has two ear plates 33.

[0047] like Figure 10 As shown, the core tube 10 includes shear walls 11 and connecting beams 12. The shear walls 11 are multiple vertically arranged, and connecting beams 12 are installed between adjacent shear walls 11. The shear walls 11 and connecting beams 12 surround and form a hollow core tube. Multiple sets of lug plates 33 are provided on opposite sides of the core tube 10. The multiple sets of lug plates 33 on one side of the core tube 10 are arranged from the top to the bottom of the shear wall 11. The multiple sets of lug plates 33 on both sides of the core tube 10 are symmetrically arranged. The multiple sets of lug plates 33 on the same side of the shear wall 11 are arranged in two rows. Multiple horizontally placed steel bars 50 are provided between the two symmetrical sets of lug plates 33. One end of the steel bar 50 is embedded in the shear wall 11, and the other end extends out to form a fixed connection with the horizontally adjacent frame module 20 by post-cast concrete.

[0048] Since the structures of the frame module 20 and the module connection assembly 40 are the same as those in the first embodiment, they will not be described in detail here.

[0051] A modular staggered core tube structure system includes a core tube 10, frame modules 20, a horizontal connection assembly 30, and a module connection assembly 40. The frame modules 20 are connected to the core tube 10 via the horizontal connection assembly 30, and adjacent frame modules 20 are connected via the module connection assembly 40. Multiple frame modules 20 are staggered and stacked to form a multi-layer rectangular main structure. Multiple frame modules 20 are arranged around multiple core tubes 10.

[0052] In this embodiment, the structures of the core tube 10, the horizontal connection assembly 30 and the module connection assembly 40 are the same as those in the second embodiment and are not described again here.

[0053] The frame module 20 includes second columns 21, second crossbeams 22, connecting beams 23, a second top plate 24, a second bottom plate 25, and a connecting plate 26. Every eight second crossbeams 22 and every four second columns 21 are connected by a module connecting assembly 40 to form a single frame. The second top plate 24 is connected to the four second crossbeams 22 at the top, and the second bottom plate 25 is connected to the four second crossbeams 22 at the bottom. One end of the four connecting beams 23 is connected to the module connecting assembly 40 and extends horizontally outward from the four crossbeams 22. The other end of each connecting beam 23 is provided with a lug 33 of the horizontal connecting assembly 30. Steel bars 50 are pre-embedded in the connecting plate 26. In this embodiment, the second columns 21, second crossbeams 22, second connecting beams 23, second top plate 24, second bottom plate 25, and connecting plate 26 are all concrete structures.
